ObjectivesThis study sought to evaluate impact of new-onset and pre-existing atrial fibrillation (AF) on transcatheter aortic valve replacement (TAVR) long-term outcomes compared with patients without AF.BackgroundPre-existing and new-onset AF in patients undergoing TAVR are associated with poor outcomes.MethodsThe study identified 72,660 patients ≥65 years of age who underwent nonapical TAVR between 2014 and 2016 using Medicare inpatient claims. History of AF was defined by diagnoses on claims during the 3 years preceding the TAVR, and new-onset AF was defined as occurrence of AF during the TAVR admission or within 30 days after TAVR in a patient without prior history of AF. Outcomes included all-cause mortality, and readmission for bleeding, stroke, and heart failure (HF).ResultsOverall, 40.7% had pre-existing AF (n = 29,563) and 6.8% experienced new-onset AF (n = 2,948) after TAVR. Mean age was 81.3, 82.4, and 83.8 years in patients with no AF, pre-existing, and new-onset AF, respectively. Pre-existing AF patients had the highest burden of comorbidities. After follow-up of 73,732 person-years, mortality was higher with new-onset AF compared with pre-existing and no AF (29.7, 22.6, and 12.8 per 100 person-years, respectively; p < 0.001). After adjusting for patient characteristics and hospital TAVR volume, new-onset AF remained associated with higher mortality compared with no AF (adjusted hazard ratio: 2.068, 95% confidence interval [CI]: 1.92 to 2.20; p < 0.01) and pre-existing AF (adjusted hazard ratio: 1.35; 95% CI: 1.26 to 1.45; p < 0.01). In competing risk analysis, new-onset AF was associated with higher risk of bleeding (subdistribution hazard ratio [sHR]: 1.66; 95% CI: 1.48 to 1.86; p < 0.01), stroke (sHR: 1.92; 95% CI: 1.63 to 2.26; p < 0.01), and HF (sHR: 1.98; 95% CI: 1.81 to 2.16; p < 0.01) compared with pre-existing AF.ConclusionsIn patients undergoing TAVR, new-onset AF is associated with increased risk of mortality and bleeding, stroke, and HF hospitalizations compared with pre-existing AF or no AF. 相似文献

BackgroundLoss of autonomy associated with nursing home admission (NHA) is a concern for patients. Yet the incidence of NHA after transcatheter aortic valve replacement (TAVR) is unknown.ObjectivesThe aim of this study was to investigate the incidence and factors associated with NHA following TAVR compared with the general population.MethodsThrough Danish registries, patients alive at discharge after TAVR were identified from January 2014 to October 2021. Patients were matched 1:5 on sex, age, and calendar year to the general population. The 3-year cumulative incidence and 95% CI of NHA were estimated using the Aalen-Johansen estimator, accounting for the competing risk for death. Through multivariate cause-specific Cox regression models, factors associated with NHA were examined.ResultsIn total, 5,312 TAVR patients were matched to 26,560 control subjects with a median age of 81 years and 56.1% males. Comorbidity burden was higher for TAVR patients. The 3-year cumulative incidence of NHA was 6.3% (95% CI: 5.5%-7.1%) for TAVR patients compared with 5.8% (95% CI: 5.4%-6.1%) for the general population. For TAVR patients >85 years of age, the cumulative incidence of NHA was 11.6% (95% CI: 9.5%-13.8%), and the risk for death was 23.3% (95% CI: 20.4%-26.2%). Factors associated with NHA were increasing age, frailty, living alone, and atrial fibrillation.ConclusionsTAVR was not associated with an increased incidence of NHA compared with the general population. Despite the increased incidence of NHA for TAVR patients >85 years of age, approximately 2 in 3 patients were still alive and not admitted to nursing homes 3 years after TAVR. 相似文献

ObjectivesThe aim of this study was to compare the feasibility, safety, and clinical outcomes of transcatheter aortic valve replacement (TAVR) in bicuspid aortic valve (BAV) versus tricuspid aortic valve (TAV) stenosis.BackgroundAt present, limited observational data exist supporting TAVR in the context of bicuspid anatomy.MethodsPrimary endpoints were 1-year survival and device success. Secondary endpoints included moderate to severe paravalvular leak (PVL) and a composite endpoint of periprocedural complications; incidence rates of individual procedural endpoints were also explored individually.ResultsIn the main analysis, 17 studies and 181,433 patients undergoing TAVR were included, of whom 6,669 (0.27%) had BAV. A secondary analysis of 7,071 matched subjects with similar baseline characteristics was also performed. Device success and 1-year survival rates were similar between subjects with BAV and those with TAV (97% vs 94% [P = 0.55] and 91.3% vs 90.8% [P = 0.22], respectively). In patients with BAV, a trend toward a higher risk for periprocedural complications was observed in our main analysis (risk ratio [RR]: 1.12; 95% CI: 0.99-1.27; P = 0.07) but not in the matched population secondary analysis (RR: 1.00; 95% CI: 0.81-1.24; P = 0.99). The risk for moderate to severe PVL was higher in subjects with BAV (RR: 1.42; 95% CI: 1.29-1.58; P < 0.0001) as well as the incidence of cerebral ischemic events (2.4% vs 1.6%; P = 0.015) and of annular rupture (0.3% vs 0.02%; P = 0.014) in matched subjects.ConclusionsTAVR is a feasible option among selected patients with BAV anatomy, but the higher rates of moderate to severe PVL, annular rupture, and cerebral ischemic events observed in the BAV group warrant caution and further evidence. 相似文献

ObjectivesThe aim of this study was to investigate the impact of valvular and nonvalvular atrial fibrillation (AF) in patients undergoing transcatheter aortic valve replacement (TAVR).BackgroundAF has been associated with adverse clinical outcomes after TAVR. However, the differential impact of valvular as opposed to nonvalvular AF has not been investigated.MethodsIn a retrospective analysis of a prospective registry, valvular AF was defined as AF in the setting of concomitant mitral stenosis or the presence of a mitral valve prosthesis. The presence of mitral stenosis was determined by pre-procedural echocardiography. The primary endpoint was a composite of cardiovascular death or disabling stroke at 1 year after TAVR.ResultsAmong 1,472 patients undergoing TAVR between August 2007 and June 2018, AF was recorded in 465 patients (31.6%) and categorized as nonvalvular in 376 (25.5%) and valvular in 89 (6.0%). AF scores including HAS-BLED, CHADS2, and CHA2DS2-VASc were comparable between patients with nonvalvular and valvular AF. The primary endpoint occurred in 9.3% of patients with no AF, in 14.5% of patients with nonvalvular AF (hazard ratio: 1.57; 95% confidence interval: 1.12 to 2.20; p = 0.009), and in 24.2% of patients with valvular AF (hazard ratio: 2.75; 95% confidence interval: 1.71 to 4.41; p < 0.001). Valvular AF conferred an increased risk for cardiovascular death or disabling stroke compared with nonvalvular AF (hazard ratio: 1.77; 95% confidence interval: 1.07 to 2.94; p = 0.027).ConclusionsThe presence of valvular AF in patients undergoing TAVR increased the risk for cardiovascular death or disabling stroke compared with both no AF and nonvalvular AF.

ObjectivesThis study was performed to investigate long-term, clinically important outcomes in patients who underwent permanent pacemaker implantation after transcatheter aortic valve replacement (TAVR).BackgroundThe impact of permanent pacemaker implantation after TAVR is unknown, and prior studies have produced conflicting results.MethodsIn this nationwide, population-based cohort study, the study included all patients who underwent transfemoral TAVR in Sweden from 2008 to 2018 from the SWEDEHEART (Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies) register. Additional baseline characteristics and information about outcomes were obtained by individual crosslinking with other national health data registers. Unadjusted and multivariable-adjusted analyses were performed using Cox proportional hazards regression.ResultsOf 3,420 patients, 481 (14.1%) underwent permanent pacemaker implantation within 30 days after TAVR. The survival rate at 1, 5, and 10 years was 90.0%, 52.7%, and 10.9% in the pacemaker group and 92.7%, 53.8%, and 15.3% in the nonpacemaker group, respectively (HR: 1.03; 95% CI: 0.88-1.22; P = 0.692). The median follow-up was 2.7 years (interquartile range: 2.5, and maximum 11.8 years). There was no difference in the risk of cardiovascular death (HR: 0.91; 95% CI: 0.71-1.18; P = 0.611), heart failure (HR: 1.23; 95% CI: 0.92-1.63; P = 0.157), or endocarditis (HR: 0.90; 95% CI: 0.47-1.69; P = 0.734) between the groups.ConclusionsThe study found no difference in long-term survival between patients who did and did not undergo permanent pacemaker implantation after TAVR. As the use of TAVR expands to include younger and low-risk patients with a long life expectancy, it will become increasingly important to understand the impact of permanent pacemaker implantation after TAVR. 相似文献

BackgroundIt remains controversial whether prosthesis-patient mismatch (PPM) (in general considered moderate if indexed effective orifice area is 0.65-0.85 cm2/m2 and severe when <0.65 cm2/m2) affects the outcomes after transcatheter aortic valve replacement (TAVR).ObjectivesThe purpose of this study is to evaluate the time-varying effects and association of PPM with the risk of overall mortality.MethodsStudy-level meta-analysis of reconstructed time-to-event data from Kaplan-Meier curves of studies published by December 30, 2021.ResultsIn total, 23 studies met our eligibility criteria and included a total of 81,969 patients included in the Kaplan-Meier curves (19,612 with PPM and 62,357 without PPM). Patients with moderate/severe PPM had a significantly higher risk of mortality compared with those without PPM (HR: 1.09 [95% CI: 1.04-1.14]; P < 0.001). In the first 30 months after the procedure, mortality rates were significantly higher in the moderate/severe PPM group (HR: 1.1 [95% CI: 1.05-1.16]; P < 0.001). In contrast, the landmark analysis beyond 30 months yielded a reversal of the HR (0.83 [95% CI: 0.68-1.01]; P = 0.064), but without statistical significance. In the sensitivity analysis, although the authors observed that severe PPM showed higher risk of mortality in comparison with no PPM (HR: 1.25 [95% CI: 1.16-1.36]; P < 0.001), they did not observe a statistically significant difference for mortality between moderate PPM and no PPM (HR: 1.03 [95% CI: 0.96-1.10]; P = 0.398).ConclusionsSevere PPM, but not moderate PPM, was associated with higher risk of mortality following TAVR. These results provide support to implementation of preventive strategies to avoid severe PPM following TAVR. 相似文献

ObjectivesThe aim of this study was to investigate age-related outcomes of patients undergoing transcatheter aortic valve replacement (TAVR) as assessed in a nationwide, prospective, multicenter cohort study.BackgroundTAVR is the preferred treatment for elderly patients with severe aortic stenosis and is expanding into lower age groups.MethodsData from the SwissTAVI Registry were analyzed. Clinical outcomes were compared between patients 70 years of age or younger (n = 324), 70 to 79 years of age (n = 1,913), 80 to 89 years of age (n = 4,353), and older than 90 years of age (n = 507). Observed deaths were correlated with expected deaths in the general Swiss population using standardized mortality ratios.ResultsBetween February 2011 and June 2018, 7,097 patients (mean age 82.0 ± 6.4 years, 49.6% women) underwent TAVR at 15 hospitals in Switzerland. Procedural characteristics were similar; however, older patients more often had discharge to the referring hospital or a rehabilitation facility after TAVR. Using adjusted analyses, a linear trend for mortality (30-day adjusted hazard ratio [HRadj]: 1.45; 95% confidence interval [CI]: 1.18 to 1.77; 1-year HRadj: 1.12; 95% CI: 1.01 to 1.24), cerebrovascular accidents (30-day HRadj: 1.35; 95% CI: 1.09 to 1.66; 1-year HRadj: 1.21; 95% CI: 1.02 to 1.45), and pacemaker implantation (30-day HRadj: 1.23; 95% CI: 1.12 to 1.34; 1-year HRadj: 1.19; 95% CI: 1.09 to 1.30) was observed with increasing age. Furthermore, standardized mortality ratios were 12.63 (95% CI: 9.06 to 17.58), 4.09 (95% CI: 3.56 to 4.74), 1.63 (95% CI: 1.50 to 1.78), and 0.93 (95% CI: 0.76 to 1.14) for TAVR patients in relation to the Swiss population <70, 70 to 79, 80 to 89 and ≥90 years of age, respectively.ConclusionsIncreasing age is associated with a linear trend for mortality, stroke, and pacemaker implantation during early and longer-term follow-up after TAVR. Standardized mortality ratios were higher for TAVR patients younger than 90 years of age compared with expected rates of mortality in an age- and sex-matched Swiss population.

ObjectivesThe aim of this study was to assess the incidence and prognostic impact of early and late postoperative atrial fibrillation or flutter (POAF) in patients with severe aortic stenosis (AS) treated with transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR).BackgroundThere is an ongoing controversy regarding the incidence, recurrence rate, and prognostic impact of early (in-hospital) POAF and late (postdischarge) POAF in patients with AS undergoing TAVR or SAVR.MethodsIn the PARTNER (Placement of Aortic Transcatheter Valve) 3 trial, patients with severe AS at low surgical risk were randomized to TAVR or SAVR. Analyses were performed in the as-treated population excluding patients with preexistent atrial fibrillation or flutter.ResultsAmong 781 patients included in the analysis, early POAF occurred in 152 (19.5%) (18 of 415 [4.3%] and 134 of 366 [36.6%] following TAVR and SAVR, respectively). Following discharge, 58 new or recurrent late POAF events occurred within 1 year following the index procedure in 55 of 781 patients (7.0%). Early POAF was not an independent predictor of late POAF following discharge (odds ratio: 1.04; 95% CI: 0.52-2.08; P = 0.90). Following adjustment, early POAF was not an independent predictor of the composite outcome of death, stroke, or rehospitalization (hazard ratio: 1.10; 95% CI: 0.64-1.92; P = 0.72), whereas late POAF was associated with an increased adjusted risk for the composite outcome (hazard ratio: 8.90; 95% CI: 5.02-15.74; P < 0.0001), irrespective of treatment modality.ConclusionsIn the PARTNER 3 trial, early POAF was more frequent following SAVR compared with TAVR. Late POAF, but not early POAF, was significantly associated with worse outcomes at 2 years, irrespective of treatment modality. 相似文献

BackgroundThe efficacy and safety of aspirin for primary prevention of cardiovascular disease (CVD) remain debatable.ObjectivesThe purpose of this study was to examine the clinical outcomes with aspirin for primary prevention of CVD after the recent publication of large trials adding >45,000 individuals to the published data.MethodsRandomized controlled trials comparing clinical outcomes with aspirin versus control for primary prevention with follow-up duration of ≥1 year were included. Efficacy outcomes included all-cause death, cardiovascular (CV) death, myocardial infarction (MI), stroke, transient ischemic attack (TIA), and major adverse cardiovascular events. Safety outcomes included major bleeding, intracranial bleeding, fatal bleeding, and major gastrointestinal (GI) bleeding. Random effects DerSimonian-Laird risk ratios (RRs) for outcomes were calculated.ResultsA total of 15 randomized controlled trials including 165,502 participants (aspirin n = 83,529, control n = 81,973) were available for analysis. Compared with control, aspirin was associated with similar all-cause death (RR: 0.97; 95% confidence interval [CI]: 0.93 to 1.01), CV death (RR: 0.93; 95% CI: 0.86 to 1.00), and non-CV death (RR: 0.98; 95% CI: 0.92 to 1.05), but a lower risk of nonfatal MI (RR: 0.82; 95% CI: 0.72 to 0.94), TIA (RR: 0.79; 95% CI: 0.71 to 0.89), and ischemic stroke (RR: 0.87; 95% CI: 0.79 to 0.95). Aspirin was associated with a higher risk of major bleeding (RR: 1.5; 95% CI: 1.33 to 1.69), intracranial bleeding (RR: 1.32; 95% CI: 1.12 to 1.55), and major GI bleeding (RR: 1.52; 95% CI: 1.34 to 1.73), with similar rates of fatal bleeding (RR: 1.09; 95% CI: 0.78 to 1.55) compared with the control subjects. Total cancer and cancer-related deaths were similar in both groups within the follow-up period of the study.ConclusionsAspirin for primary prevention reduces nonfatal ischemic events but significantly increases nonfatal bleeding events. 相似文献

ObjectivesUsing French transcatheter aortic valve replacement (TAVR) registries linked with the nationwide administrative databases, the study compared the rates of long-term mortality, bleeding, and ischemic events after TAVR in patients requiring oral anticoagulation with direct oral anticoagulants (DOACs) or vitamin K antagonists (VKAs).BackgroundThe choice of optimal drug for anticoagulation after TAVR remains debated.MethodsData from the France-TAVI and FRANCE-2 registries were linked to the French national health single-payer claims database, from 2010 to 2017. Propensity score matching was used to reduce treatment-selection bias. Two primary endpoints were death from any cause (efficacy) and major bleeding (safety).ResultsA total of 24,581 patients who underwent TAVR were included and 8,962 (36.4%) were treated with OAC. Among anticoagulated patients, 2,180 (24.3%) were on DOACs. After propensity matching, at 3 years, mortality (hazard ratio [HR]: 1.37; 95% confidence interval [CI]: 1.12-1.67; P < 0.005) and major bleeding including hemorrhagic stroke (HR: 1.64; 95% CI: 1.17-2.29; P < 0.005) were lower in patients on DOACs compared with those on VKAs. The rates of ischemic stroke (HR: 1.32; 95% CI: 0.81-2.15; P = 0.27) and acute coronary syndrome (HR: 1.17; 95% CI: 0.68-1.99; P = 0.57) did not differ among groups.ConclusionsIn these large multicenter French TAVR registries with an exhaustive clinical follow-up, the long-term mortality and major bleeding were lower with DOACs than VKAs at discharge. The present study supports preferential use of DOACs rather than VKAs in patients requiring oral anticoagulation therapy after TAVR. 相似文献

Background:Presently, transcatheter aortic valve replacement (TAVR) as an effective and convenient intervention has been adopted extensively for patients with severe aortic disease. However, after surgical aortic valve replacement (SAVR) and TAVR, the incidence of new-onset atrial fibrillation (NOAF) is prevalently found. This meta-analysis was designed to comprehensively compare the incidence of NOAF at different times after TAVR and SAVR for patients with severe aortic disease.Methods:A systematic search of PubMed, Embase, Cochrane Library, and Web of Science up to October 1, 2020 was conducted for relevant studies that comparing TAVR and SAVR in the treatment of severe aortic disease. The primary outcomes were the incidence of NOAF with early, midterm and long term follow-up. The secondary outcomes included permanent pacemaker (PM) implantation, myocardial infarction (MI), cardiogenic shock, as well as mortality and other complications. Two reviewers assessed trial quality and extracted the data independently. All statistical analyses were performed using the standard statistical procedures provided in Review Manager 5.2.Results:A total of 16 studies including 13,310 patients were identified. The pooled results indicated that, compared with SAVR, TAVR experienced a significantly lower incidence of 30-day/in-hospital, 1-year, 2-year, and 5-year NOAF, with pooled risk ratios (RRs) of 0.31 (95% confidence interval [CI] 0.23–0.41; 5725 pts), 0.30 (95% CI 0.24–0.39; 6321 pts), 0.48 (95% CI 0.38–0.61; 3441 pts), and 0.45 (95% CI 0.37–0.55; 2268 pts) respectively. In addition, TAVR showed lower incidence of MI (RR 0.62; 95% CI 0.40–0.97) and cardiogenic shock (RR 0.34; 95% CI 0.19–0.59), but higher incidence of permanent PM (RR 3.16; 95% CI 1.61–6.21) and major vascular complications (RR 2.22; 95% CI 1.14–4.32) at 30-day/in-hospital. At 1- and 2-year after procedure, compared with SAVR, TAVR experienced a significantly higher incidence of neurological events, transient ischemic attacks (TIA), permanent PM, and major vascular complications, respectively. At 5-year after procedure, compared with SAVR, TAVR experienced a significantly higher incidence of TIA and re-intervention respectively. There was no difference in 30-day, 1-year, 2-year, and 5-year all-cause or cardiovascular mortality as well as stroke between TAVR and SAVR.Conclusions:Our analysis showed that TAVR was superior to SAVR in decreasing the both short and long term postprocedural NOAF. TAVR was equal to SAVR in early, midterm and long term mortality. In addition, TAVR showed lower incidence of 30-day/in-hospital MI and cardiogenic shock after procedure. However, pooled results showed that TAVR was inferior to SAVR in reducing permanent pacemaker implantation, neurological events, TIA, major vascular complications, and re-intervention. 相似文献

ObjectivesThis study sought to evaluate the incidence and outcomes of endocarditis after transcatheter aortic valve replacement (TAVR).BackgroundData about endocarditis after TAVR are limited.MethodsThe study investigated Medicare patients who underwent TAVR from 2012 to 2017 and identified patients admitted with endocarditis during follow-up using a validated algorithm. The main study outcome was all-cause mortality.ResultsOf 134,717 patients who underwent TAVR, 1868 patients developed endocarditis during follow-up (incidence 0.87%/year), with majority of infections (65.0%) occurring within 1 year. Incidence of endocarditis declined in recent years. The most common organisms were Staphylococcus (22.0%), Streptococcus (20.0%), and Enterococcus (15.5%). Important predictors for endocarditis were younger age at TAVR, male sex, prior endocarditis, end-stage renal disease, repeat TAVR procedures, liver and lung disease, and post-TAVR acute kidney injury. Thirty-day and 1-year mortality were 18.5% and 45.6%, respectively. After adjusting for comorbidities and procedural complications, endocarditis after TAVR was associated with 3-fold higher risk of mortality (44.9 vs. 16.2 deaths per 100 person-years; adjusted hazard ratio [aHR]: 2.94; 95% confidence interval [CI]: 2.77 to 3.12; p < 0.0001). End-stage renal disease (aHR: 2.12; 95% CI: 1.72 to 2.60), endocarditis complicated by cardiogenic shock (aHR: 2.50, 95% CI: 1.56 to 4.02), ischemic stroke (aHR: 1.56; 95% CI: 1.07 to 2.28), intracerebral hemorrhage (aHR: 1.67; 95% CI: 1.01 to 2.76), acute kidney injury (aHR: 1.44; 95% CI: 1.27 to 1.63), blood transfusion (aHR: 1.28; 95% CI: 1.09 to 1.50), staphylococcal (aHR: 1.71; 95% CI: 1.49 to 1.97), and fungal endocarditis (aHR: 1.72; 95% CI: 1.23 to 2.39) (p < 0.05 for all) portended higher mortality following endocarditis.ConclusionsThe incidence of endocarditis after TAVR is low and declining. However, it is associated with poor prognosis with one-half the patients dying within 1 year. 相似文献

ObjectivesThe authors aimed to investigate the rates, predictors, and prognostic impact of technical success in patients undergoing transcatheter aortic valve replacement (TAVR).BackgroundThe Valve Academic Research Consortium-3 (VARC-3) has introduced a composite endpoint to assess the immediate technical success of TAVR.MethodsIn the prospective Bern TAVR registry, patients were stratified according to VARC-3 technical success. Technical failure differentiated between vascular and cardiac complications.ResultsIn a total of 1,624 patients undergoing TAVR between March 2012 and December 2019, 1,435 (88.4%) patients had technical success. Among 189 patients with technical failure, 140 (8.6%) had vascular and 49 (3.0%) had cardiac technical failure. Female, larger device landing zone calcium volume, and the early term of the study period were associated with an increased risk for cardiac technical failure, whereas higher body mass index and the use of the Prostar (Abbott Vascular Inc) MANTA (Teleflex) (compared with the ProGlide [Abbott Vascular Inc]) were predictors of vascular technical failure. In multivariable analysis, technical failure conferred an increased risk for cardiovascular death or stroke (HR: 2.01; 95% CI: 1.37-2.95). The adverse effect remained when stratified to cardiac (HR: 2.62; 95% CI: 1.38-4.97) or vascular technical failure (HR: 1.95; 95% CI: 1.28-2.95) and limited to the periprocedural period (0-30 days: HR: 3.42 [95% CI: 2.05-5.69]; 30-360 days: HR: 1.36 [95% CI: 0.79-2.35]; P for interaction = 0.002).ConclusionsTechnical failure according to VARC-3 was observed in 1 of 10 patients undergoing TAVR and was associated with a 2-fold increased risk of the composite outcome at 1 year after TAVR.

ObjectivesThe aim of this study was to evaluate early results of valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) versus redo surgical aortic valve replacement (SAVR) for structural valve degeneration (SVD).BackgroundViV TAVR has been increasingly used for SVD, but it remains unknown whether it produces better or at least comparable results as redo SAVR.MethodsObservational studies comparing ViV TAVR and redo SAVR were identified in a systematic search of published research. Random-effects meta-analysis was performed, comparing clinical outcomes between the 2 groups.ResultsTwelve publications including a total of 16,207 patients (ViV TAVR, n = 8,048; redo SAVR, n = 8,159) were included from studies published from 2015 to 2020. In the pooled analysis, ViV TAVR was associated with lower rates of 30-day mortality overall (odds ratio [OR]: 0.52; 95% confidence interval [CI]: 0.39 to 0.68; p < 0.001) and for matched populations (OR: 0.419; 95% CI: 0.278 to 0.632; p = 0.003), major bleeding (OR 0.48; 95% CI: 0.28 to 0.80; p = 0.013), as well as with shorter hospital stay (OR: ?3.30; 95% CI: ?4.52 to ?2.08; p < 0.001). In contrast, ViV TAVR was associated with higher rates of severe patient-prosthesis mismatch (OR: 4.63; 95% CI: 3.05 to 7.03; p < 0.001). The search revealed an important lack of comparative studies with long-term results.ConclusionsViV TAVR is a valuable option in the treatment of patients with SVD because of its lower incidence of post-operative complications and better early survival compared with redo SAVR. However, ViV TAVR is associated with higher rates of myocardial infarction and severe patient-prosthesis mismatch. 相似文献

BackgroundPatients on long-term dialysis are at increased risk of bleeding. Although oral anticoagulants (OACs) are recommended for atrial fibrillation (AF) to reduce the risk of stroke, randomized trials have excluded these populations. As such, the net clinical benefit of OACs among patients on dialysis is unknown.ObjectivesThis study aimed to investigate the efficacy and safety of OACs in patients with AF on long-term dialysis.MethodsMEDLINE and EMBASE were searched through June 10, 2019, for studies that investigated the efficacy and safety of different OAC strategies in patients with AF on long-term dialysis. The efficacy outcomes were ischemic stroke and/or systemic thromboembolism, all-cause mortality, and the safety outcome was major bleeding.ResultsThis study identified 16 eligible observational studies (N = 71,877) regarding patients on long-term dialysis who had AF. Only 2 of 16 studies investigated direct OACs. Outcomes for dabigatran and rivaroxaban were limited to major bleeding events. Compared with no anticoagulants, apixaban and warfarin were not associated with a significant decrease in stroke and/or systemic thromboembolism (apixaban 5 mg, hazard ratio [HR]: 0.59; 95% confidence interval [CI]: 0.30 to 1.17; apixaban 2.5 mg, HR: 1.00; 95% CI: 0.52 to 1.93; warfarin, HR: 0.91; 95% CI: 0.72 to 1.16). Apixaban 5 mg was associated with a significantly lower risk of mortality (vs. warfarin, HR: 0.65; 95% CI: 0.45 to 0.93; vs. apixaban 2.5 mg, HR: 0.62; 95% CI: 0.42 to 0.90; vs. no anticoagulant, HR: 0.61; 95% CI: 0.41 to 0.90). Warfarin was associated with a significantly higher risk of major bleeding than apixaban 5 min/2.5 mg and no anticoagulant (vs. apixaban 5 mg, HR: 1.41; 95% CI: 1.07 to 1.88; vs. apixaban 2.5 mg, HR: 1.40; 95% CI: 1.07 to 1.82; vs. no anticoagulant, HR: 1.31; 95% CI: 1.15 to 1.50). Dabigatran and rivaroxaban were also associated with significantly higher risk of major bleeding than apixaban and no anticoagulant.ConclusionsThis meta-analysis showed that OACs were not associated with a reduced risk of thromboembolism in patients with AF on long-term dialysis. Warfarin, dabigatran, and rivaroxaban were associated with significantly higher bleeding risk compared with apixaban and no anticoagulant. The benefit-to-risk ratio of OACs in patients with AF on long-term dialysis warrants validation in randomized clinical trials. 相似文献

BackgroundLeft ventricular abnormalities in cardiac sarcoidosis (CS) are associated with adverse cardiovascular events, whereas the prognostic value of right ventricular (RV) involvement found on cardiac magnetic resonance is unclear.ObjectivesThis study aimed to systematically assess the prognostic value of right ventricular ejection fraction (RVEF) and RV late gadolinium enhancement (LGE) in known or suspected CS.MethodsThis study was prospectively registered in PROSPERO (CRD42022302579). PubMed, Embase, and Web of Science were searched to identify studies that evaluated the association between RVEF or RV LGE on clinical outcomes in CS. A composite endpoint of all-cause death, cardiovascular events, or sudden cardiac death (SCD) was used. A meta-analysis was performed to determine the pooled risk ratio (RR) for these adverse events. The calculated sensitivity, specificity, and area under the curve with 95% CIs were weighted and summarized.ResultsEight studies including a total of 899 patients with a mean follow-up duration of 3.2 ± 0.7 years were included. The pooled RR of RV systolic dysfunction was 3.1 (95% CI: 1.7-5.5; P < 0.01) for composite events and 3.0 (95% CI: 1.3-7.0; P < 0.01) for SCD events. In addition, CS patients with RV LGE had a significant risk for composite events (RR: 4.8 [95% CI: 2.4-9.6]; P < 0.01) and a higher risk for SCD (RR: 9.5 [95% CI: 4.4-20.5]; P < 0.01) than patients without RV LGE. Furthermore, the pooled area under the curve, sensitivity, and specificity of RV LGE for identifying patients with CS who were at highest SCD risk were 0.8 (95% CI: 0.8-0.9), 69% (95% CI: 50%-84%), and 90% (95% CI: 70%-97%), respectively.ConclusionsIn patients with known or suspected CS, RVEF and RV LGE were both associated with adverse events. Furthermore, RV LGE shows good discrimination in identifying CS patients at high risk of SCD. 相似文献

ObjectivesThe aim of this study was to compare, in a cohort of patients with complex coronary artery disease (CAD) and severe aortic stenosis (AS), the clinical outcomes associated with transfemoral transcatheter aortic valve replacement (TAVR) (plus percutaneous coronary intervention [PCI]) versus surgical aortic valve replacement (SAVR) (plus coronary artery bypass grafting [CABG]).BackgroundPatients with complex CAD were excluded from the main randomized trials comparing TAVR with SAVR, and no data exist comparing TAVR + PCI vs SAVR + CABG in such patients.MethodsA multicenter study was conducted including consecutive patients with severe AS and complex CAD (SYNTAX [Synergy Between PCI with Taxus and Cardiac Surgery] score >22 or unprotected left main disease). A 1:1 propensity-matched analysis was performed to account for unbalanced covariates. The rates of major adverse cardiac and cerebrovascular events (MACCE), including all-cause mortality, nonprocedural myocardial infarction, need for new coronary revascularization, and stroke, were evaluated.ResultsA total of 800 patients (598 undergoing SAVR + CABG and 202 undergoing transfemoral TAVR + PCI) were included, and after propensity matching, a total of 156 pairs of patients were generated. After a median follow-up period of 3 years (interquartile range: 1-6 years), there were no significant differences between groups for MACCE (HR for transfemoral TAVR vs SAVR: 1.33; 95% CI: 0.89-1.98), all-cause mortality (HR: 1.25; 95% CI: 0.81-1.94), myocardial infarction (HR: 1.16; 95% CI: 0.41-3.27), and stroke (HR: 0.42; 95% CI: 0.13-1.32), but there was a higher rate of new coronary revascularization in the TAVR + PCI group (HR: 5.38; 95% CI: 1.73-16.7).ConclusionsIn patients with severe AS and complex CAD, TAVR + PCI and SAVR + CABG were associated with similar rates of MACCE after a median follow-up period of 3 years, but TAVR + PCI recipients exhibited a higher risk for repeat coronary revascularization. Future trials are warranted. 相似文献

BackgroundInfective endocarditis may affect patients after transcatheter aortic valve replacement (TAVR).ObjectivesThe purpose of this study was to provide detailed information on incidence rates, types of microorganisms, and outcomes of infective endocarditis after TAVR.MethodsBetween February 2011 and July 2018, consecutive patients from the SwissTAVI Registry were eligible. Infective endocarditis was classified into early (peri-procedural [<100 days] and delayed-early [100 days to 1 year]) and late (>1 year) endocarditis. Clinical events were adjudicated according to the Valve Academic Research Consortium-2 endpoint definitions.ResultsDuring the observational period, 7,203 patients underwent TAVR at 15 hospitals in Switzerland. During follow-up of 14,832 patient-years, endocarditis occurred in 149 patients. The incidence for peri-procedural, delayed-early, and late endocarditis after TAVR was 2.59, 0.71, and 0.40 events per 100 person-years, respectively. Among patients with early endocarditis, Enterococcus species were the most frequently isolated microorganisms (30.1%). Among those with peri-procedural endocarditis, 47.9% of patients had a pathogen that was not susceptible to the peri-procedural antibiotic prophylaxis. Younger age (subhazard ratio [SHR]: 0.969; 95% confidence interval [CI]: 0.944 to 0.994), male sex (SHR: 1.989; 95% CI: 1.403 to 2.818), lack of pre-dilatation (SHR: 1.485; 95% CI: 1.065 to 2.069), and treatment in a catheterization laboratory as opposed to hybrid operating room (SHR: 1.648; 95% CI: 1.187 to 2.287) were independently associated with endocarditis. In a case-control matched analysis, patients with endocarditis were at increased risk of mortality (hazard ratio: 6.55; 95% CI: 4.44 to 9.67) and stroke (hazard ratio: 4.03; 95% CI: 1.54 to 10.52).ConclusionsInfective endocarditis after TAVR most frequently occurs during the early period, is commonly caused by Enterococcus species, and results in considerable risks of mortality and stroke.

ObjectivesThe aim of this study was to assess the impact of aortic valve replacement (AVR) on survival in patients with each subclass of low-gradient (LG) aortic stenosis (AS) and to compare outcomes following surgical AVR (SAVR) and transcatheter AVR (TAVR).BackgroundLG severe AS encompasses a wide variety of pathophysiology, including classical low-flow, LG (LF-LG), paradoxical LF-LG, and normal-flow, LG (NF-LG) AS, and uncertainty exists regarding the impact of AVR on each subclass of LG AS.MethodsPubMed and Embase were queried through October 2020 to identify studies comparing survival with different management strategies (SAVR, TAVR, and conservative) in patients with LG AS. Pairwise meta-analysis comparing AVR versus conservative management and network meta-analysis comparing SAVR versus TAVR versus conservative management were performed.ResultsThirty-two studies with a total of 6,515 patients and a median follow-up time of 24.2 months (interquartile range: 36.5 months) were included. AVR was associated with a significant decrease in all-cause mortality in classical LF-LG (hazard ratio [HR]: 0.42; 95% confidence interval [CI]: 0.36 to 0.48), paradoxical LF-LG (HR: 0.41; 95% CI: 0.29 to 0.57), and NF-LG (HR: 0.41; 95% CI: 0.27 to 0.62) AS compared with conservative management. SAVR and TAVR were each associated with a decrease in all-cause mortality in classical LF-LG (HR: 0.46 [95% CI: 0.38 to 0.55] and 0.49 [95% CI: 0.37 to 0.64], respectively), paradoxical LF-LG (HR: 0.42 [95% CI: 0.28 to 0.65] and 0.42 [95% CI: 0.25 to 0.72], respectively), and NF-LG (HR: 0.40 [95% CI: 0.21 to 0.77] and 0.46 [95% CI: 0.26 to 0.84], respectively) AS compared with conservative management. No significant difference was observed between SAVR and TAVR.ConclusionsIn all subclasses of LG AS, AVR was associated with a significant decrease in all-cause mortality regardless of surgical or transcatheter approach. 相似文献
