ObjectivesThe aim of this study was to compare outcomes after transcatheter aortic valve replacement (TAVR) in patients with pure aortic stenosis (AS) (i.e., no or trivial associated aortic regurgitation [AR]) with those in patients with AS and mild or more severe AR (i.e., mixed aortic valve disease [MAVD]).BackgroundTAVR is indicated in treating patients with severe AS. Limited data exist regarding the outcomes of TAVR in patients with MAVD.MethodsA total of 1,133 patients who underwent TAVR between January 2014 and December 2017 were included. The primary outcome was all-cause mortality. The comparison was adjusted to account for post-TAVR AR development in both groups. The secondary outcomes included composite endpoints of early safety and clinical efficacy as specified in the Valve Academic Research Consortium-2 criteria. Variables were compared using Mann-Whitney, chi-square, and Fisher exact tests, while Kaplan-Meier analyses were used to compare survival.ResultsA total of 688 patients (61%) had MAVD (median age 83 years , 43% women). Among these, 17% developed mild, 2% moderate, and <1% severe post-TAVR AR. Overall, patients with MAVD had better survival compared with patients with pure AS (p = 0.03). Among patients who developed post-TAVR AR, those in the MAVD group had better survival (p = 0.04). In contrast, in patients who did not develop post-TAVR AR, pre-TAVR AR did not improve survival (p = 0.11).ConclusionsPatients with MAVD who underwent TAVR had better survival compared with patients with pure AS. This is explained by the better survival of patients with MAVD who developed post-TAVR AR, likely due to left ventricular adaptation to AR. 相似文献

Objectives
This study sought to evaluate the trends in isolated surgical aortic valve replacement (SAVR) procedures across hospitals with different transcatheter aortic valve replacement (TAVR) volumes among Medicare beneficiaries.Background
The volume of TAVR has increased in the United States since its approval, now exceeding that of isolated SAVR.Methods
Hospitalizations of adults (≥18 years of age) with International Classification of Diseases-9th Revision-Clinical Modification procedure codes for SAVR (35.21 or 35.22) or TAVR (35.05 or 35.06) who were included in the Medicare Provider Analysis and Review database between January 1, 2011, and December 31, 2014, were included. Trends in isolated SAVR patient characteristics, procedural volumes, and outcomes by quartile (Q) of hospital-level TAVR use were assessed over the study period.Results
A total of 37,705 isolated SAVR procedures were analyzed for the study. The annual volume of isolated SAVR procedures decreased in hospitals performing the largest number of TAVR procedures (Q3: 1,557 in 2011 to 1,391 in 2014; and Q4: 2,607 in 2011 to 1,791 in 2014). Thirty-day and 1-year mortality after SAVR also declined over the study period in hospitals with the largest TAVR volume (annual change rate in mortality for Q3: ?16.4%; p < 0.001; Q4: ?20.8%; p < 0.001).Conclusions
The advent of TAVR was associated with a reduction in isolated SAVR volumes, a decrease in comorbidities among patients undergoing SAVR, and corresponding reductions in observed short- and long-term SAVR mortality among hospitals performing the greatest number of TAVRs. 相似文献4.

Objectives
The aims of this study were to report on the use of local anesthesia or conscious sedation (LACS) and general anesthesia in transcatheter aortic valve replacement and to analyze the impact on outcome.Background
Transcatheter aortic valve replacement can be performed in LACS or general anesthesia. Potential benefits of LACS, such as faster procedures and shorter hospital stays, need to be balanced with safety.Methods
A total of 16,543 patients from the German Aortic Valve Registry from 2011 to 2014 were analyzed, and propensity-matched analyses were performed to correct for potential selection bias.Results
LACS was used in 49% of patients (8,121 of 16,543). In hospital, LACS was associated with lower rates of low-output syndrome, respiratory failure, delirium, cardiopulmonary resuscitation, and death. There was no difference in paravalvular leakage (II+) between LACS and general anesthesia in the entire population (5% vs. 4.8%; p = 0.76) or in the matched population (3.9% vs. 4.9%, p = 0.13). The risk for prolonged intensive care unit stay (≥3 days) was significantly reduced with LACS (odds ratio: 0.82; 95% confidence interval [CI]: 0.73 to 0.92; p = 0.001). Thirty-day mortality was lower with LACS in the entire population (3.5% vs. 4.9%; hazard ratio [HR]: 0.72; 95% CI: 0.60 to 0.86; p < 0.001) and in the matched population (2.8% vs. 4.6%; HR: 0.6; 95% CI: 0.45 to 0.8; p < 0.001). However, no differences in 1-year mortality between both groups in the entire population (16.5% vs. 16.9%; HR: 0.93; 95% CI: 0.85 to 1.02; p = 0.140) and in the propensity-matched population (14.1% vs. 15.5%; HR: 0.90; 95% CI: 0.78 to 1.03; p = 0.130) were observed.Conclusions
Use of LACS in transcatheter aortic valve replacement is safe, with fewer post-procedural complications and lower early mortality, suggesting its broad application. 相似文献5.

ObjectivesThe purpose of the study was to investigate the impact of oral anticoagulation (OAC) type on clinical outcomes 1 year after transcatheter aortic valve replacement (TAVR).BackgroundNon–vitamin K oral anticoagulants (NOACs) are superior to vitamin K antagonists (VKAs) in nonvalvular atrial fibrillation (AF), while their comparative performance among patients in need of OAC undergoing TAVR is underinvestigated.MethodsThe study enrolled 962 consecutive patients who underwent TAVR in 4 tertiary European centers and were discharged on either NOACs (n = 326) or VKAs (n = 636). By using propensity scores for inverse probability of treatment weighting (IPTW), the comparison of treatment groups was adjusted to correct for potential confounding.ResultsMean age and Society of Thoracic Surgeons score of the population were 81.3 ± 6.3 years and 4.5% (interquartile range: 3.0% to 7.3%); 52.5% were women and a balloon-expandable valve was used in 62.7% of cases. The primary outcome of interest, combined incidence of all-cause mortality, myocardial infarction, and any cerebrovascular event at 1-year after TAVR, was 21.2% with NOACs versus 15.0% with VKAs (hazard ratio [HR]: 1.44; 95% confidence interval [CI]: 1.00 to 2.07; p = 0.050, IPTW-adjusted). The 1-year incidence of any Bleeding Academic Research Consortium bleeds and all-cause mortality were comparable between the NOAC and VKA groups, 33.9% versus 34.1% (HR: 0.97; 95% CI: 0.74 to 1.26; p = 0.838, IPTW-adjusted) and 16.5% versus 12.2% (HR: 1.36; 95% CI: 0.90 to 2.06; p = 0.136, IPTW-adjusted), respectively.ConclusionsChronic use of both NOACs and VKAs among patients in need of OAC after TAVR are comparable regarding 1-year bleeding risk. The higher ischemic event rate observed with NOACs needs to be evaluated in large randomized trials. 相似文献

Prosthesis-patient mismatch (PPM) occurs when the effective orifice area (EOA) of the prosthetic valve is too small in relation to a patient’s body size, thus resulting in high residual postoperative pressure gradients across the prosthesis. Severe PPM occurs in 2% to 20% of patients undergoing surgical aortic valve replacement (AVR) and is associated with 1.5- to 2.0-fold increase in the risk of mortality and heart failure rehospitalization. The purpose of this article is to present an overview of the role of multimodality imaging in the assessment, prediction, prevention, and management of PPM following AVR. The risk of PPM can be anticipated at the time of AVR by calculating the predicted indexed from the normal reference value of EOA of the selected prosthesis and patient’s body surface area. The strategies to prevent PPM at the time of surgical AVR include: 1) implanting a newer generation of prosthetic valve with better hemodynamic; 2) enlarging the aortic root or annulus to accommodate a larger prosthetic valve; or 3) performing TAVR rather than surgical AVR. The identification and quantitation of PPM as well as its distinction versus prosthetic valve stenosis is primarily based on transthoracic echocardiography, but important information may be obtained from other imaging modalities such as transesophageal echocardiography and multidetector computed tomography. PPM is characterized by high transprosthetic velocity and gradients, normal EOA, small indexed EOA, and normal leaflet morphology and mobility. Transesophageal echocardiography and multidetector computed tomography are particularly helpful to assess prosthetic valve leaflet morphology and mobility, which is a cornerstone of the differential diagnosis between PPM and pathologic valve obstruction. Severe symptomatic PPM following AVR with a bioprosthetic valve may be treated by redo surgery or the transcatheter valve-in-valve procedure with fracturing of the surgical valve stent. 相似文献

Background
The burden oral anticoagulation is a limitation of mechanical valve prostheses.Objectives
The aim of this study was to test whether patients could be safely managed with dual-antiplatelet therapy (DAPT) (aspirin 325 mg and clopidogrel 75 mg) or lower warfarin after On-X mechanical aortic valve replacement (mAVR).Methods
PROACT (Prospective Randomized On-X Anticoagulation Trial) (n = 576) is a multicenter (41 sites) noninferiority trial. From June 2006 through February 2014, 201 patients ≥18 years of age without thromboembolic risk factors undergoing mAVR were randomized to receive DAPT (n = 99) or standard warfarin plus aspirin (n = 102) 3 months after mAVR (low-risk arm). From June 2006 through October 2009, 375 patients with 1 or more thromboembolic risk factors were also randomized to lower intensity warfarin plus aspirin (international normalized ratio 1.5 to 2.0; n = 185) or standard warfarin plus aspirin (international normalized ratio 2.0 to 3.0; n = 190) 3 months after mAVR (high-risk arm).Results
The low-risk arm was terminated for excess cerebral thromboembolic events (3.12% per patient-year vs. 0.29% per patient-year, p = 0.02) in the DAPT group at up to 8.8-year follow-up (631.6 patient-years), with no differences in bleeding or all-cause mortality. High-risk arm patients experienced significantly lower major (1.59% per patient-year vs. 3.94% per patient-year, p = 0.002) and minor (1.27% per patient-year vs. 3.49% per patient-year, p = 0.002) bleeding up to 8.7-year follow-up (2,035.2 patient-years), with no differences in thromboembolism (0.42% per patient-year vs. 0.09% per patient-year, p = 0.20) and all-cause mortality.Conclusions
DAPT was associated with higher rates of thromboembolism and valve thrombosis compared with control in the low-risk arm. International normalized ratios were safely maintained at 1.5 to 2.0 in high-risk patients, without differences in mortality or thromboembolic complications.

Background
There is little information concerning infective endocarditis (IE) in patients with bicuspid aortic valve (BAV) or mitral valve prolapse (MVP). Currently, IE antibiotic prophylaxis (IEAP) is not recommended for these conditions.Objectives
This study sought to describe the clinical and microbiological features of IE in patients with BAV and MVP and compare them with those of IE patients with and without IEAP indication, to determine the potential benefit of IEAP in these conditions.Methods
This analysis involved 3,208 consecutive IE patients prospectively included in the GAMES (Grupo de Apoyo al Manejo de la Endocarditis infecciosa en España) registry at 31 Spanish hospitals. Patients were classified as high-risk IE with IEAP indication (high-risk group; n = 1,226), low- and moderate-risk IE without IEAP indication (low/moderate-risk group; n = 1,839), and IE with BAV (n = 54) or MVP (n = 89).Results
BAV and MVP patients had a higher incidence of viridans group streptococci IE than did high-risk group and low/moderate-risk group patients (35.2% and 39.3% vs. 12.1% and 15.0%, respectively; all p < 0.01). A similar pattern was seen for IE from suspected odontologic origin (14.8% and 18.0% vs. 5.8% and 6.0%; all p < 0.01). BAV and MVP patients had more intracardiac complications than did low/moderate-risk group (50% and 47.2% vs. 30.6%, both p < 0.01) patients and were similar to high-risk group patients.Conclusions
IE in patients with BAV and MVP have higher rates of viridans group streptococci IE and IE from suspected odontologic origin than in other IE patients, with a clinical profile similar to that of high-risk IE patients. Our findings suggest that BAV and MVP should be classified as high-risk IE conditions and the case for IEAP should be reconsidered. 相似文献10.

The management of patients with valvular heart disease is increasingly reliant on multimodal cardiac imaging. In patients with severe aortic stenosis considered for transcatheter aortic valve replacement, careful pre-procedural planning with multimodal imaging is necessary to avoid and prevent complications during the procedure. During or immediately after the procedure, rapid echocardiographic assessment is important to assess the new valve’s function and manage major complications. Echocardiography, cardiac computed tomography, and cardiac magnetic resonance imaging all share important roles in the post-procedural evaluation of abnormal transcatheter valve function. This review discusses the use of multimodal imaging for predicting, detecting, and managing complications after TAVR. 相似文献

Objectives
This study sought to evaluate whether a multimarker approach might identify patients with higher mortality and hospitalization rates after aortic valve replacement (AVR) for aortic stenosis (AS).Background
The society valve guidelines include accepted triggers for AVR in patients with severe asymptomatic AS, but circulating biomarkers do not have a clear role.Method
From a prospective registry of patients undergoing cardiac surgery between 2000 and 2012, 665 treated with surgical AVR (441 isolated) were evaluated. Seven biomarkers were measured on blood samples obtained before AVR. Biomarker levels were adjusted to account for the influence of age, sex, body mass index, and renal function; the median was used to determine an elevated value. Endpoints included all-cause mortality and all-cause and cardiovascular hospitalizations. Mean follow-up was 10.7 years and 299 (45%) died.Results
Patients with 0 to 1, 2 to 3, 4 to 6, and 7 biomarkers elevated had 5-year mortality of 10%, 12%, 24%, and 33%, respectively, and 10-year mortality of 24%, 35%, 58%, and 71%, respectively (log-rank p < 0.001). The association between an increasing number of elevated biomarkers and increased all-cause mortality was observed among those with minimal symptoms (New York Heart Association functional class I or II) and those with a low N-terminal pro–B-type natriuretic peptide (p < 0.01 for both). Compared with those with 0 to 1 biomarkers elevated, patients with 4 to 6 or 7 biomarkers elevated had an increased hazard of mortality after adjustment for clinical risk scores (p < 0.01) and a 2- to 3-fold higher rate of all-cause and cardiovascular rehospitalization after AVR. Similar findings were obtained when evaluating cardiovascular mortality. Among patients with no or minimal symptoms, 42% had ≥4 biomarkers elevated.Conclusions
Among patients with severe AS treated with surgical AVR, an increasing number of elevated biomarkers of cardiovascular stress was associated with higher all-cause and cardiovascular mortality and a higher rate of repeat hospitalization. A multimarker approach may be useful in the surveillance of asymptomatic patients with severe AS to optimize surgical timing. 相似文献14.

ObjectivesThe aim of this study was to compare the rate and trend of vascular complications when placing a second arterial sheath in the contralateral femoral artery during transcatheter aortic valve replacement (TAVR) unilaterally versus bilaterally.BackgroundVascular complications occur in approximately 5% to 8% of TAVR procedures. Many operators place a second arterial sheath in the contralateral femoral artery to perform aortic root angiography. The authors surmised that placing the second sheath ipsilateral and distal to the delivery sheath would be an easier option with similar safety.MethodsThe Cleveland Clinic Aortic Valve Center TAVR database was accessed, and data for patients undergoing transfemoral TAVR (TF-TAVR) from January 2014 to December 2017 were analyzed retrospectively. The primary outcome was the rate of peripheral vascular complications.ResultsA total of 1,208 patients who underwent TF-TAVR were included in this study. One thousand seven patients (83.36%) underwent bilateral femoral access, and 201 patients (16.64%) underwent TF-TAVR using a unilateral femoral approach. Over the study duration, use of the unilateral access approach trended upward significantly, reaching 43.7% of total cases in 2017. A gradual decline in access site–related vascular complications was observed, from 13.7% in 2014 to 7.4% in 2017. After propensity-score matching, peripheral vascular complications were similar between bilateral access and unilateral access (10.8% vs. 8.6%) (p = 0.543).ConclusionsThere was a significant decline in vascular complications from 2014 to 2017. Unilateral-access TF-TAVR provided similar safety compared with bilateral-access TF-TAVR and is a more accessible approach for managing access site–related complications and possibly achieving better patient satisfaction. 相似文献

ObjectivesThe aim of this study was to assess the association of baseline left ventricular diastolic dysfunction (LVDD) with health status outcomes of patients undergoing transcatheter aortic valve replacement (TAVR).BackgroundAlthough LVDD in patients with aortic stenosis is associated with higher mortality after TAVR, it is unknown if it is also associated with health status recovery.MethodsIn a cohort of 304 patients with interpretable echocardiograms, undergoing TAVR, LVDD was categorized at baseline as absent (grade 0), mild (grade 1), moderate (grade 2), or severe (grade 3). Disease-specific health status was assessed using the 12-item Kansas City Cardiomyopathy Questionnaire overall summary score (KCCQ-OS) at baseline and at 1-month and 12-month follow-up. Association of baseline LVDD with health status at baseline and follow-up after TAVR was assessed using a linear trend test, and association with health status recovery (change in KCCQ-OS) was examined using a linear mixed model adjusting for baseline KCCQ-OS.ResultsTwenty-four (7.9%), 54 (17.8%), 186 (61.2%), and 40 (13.2%) patients had LVDD grades of 0, 1, 2, and 3, respectively. Baseline KCCQ-OS was 61.3 ± 22.7, 51.0 ± 26.1, 44.7 ± 25.7, and 44.4 ± 21.9 (p = 0.004) in patients with LVDD grades of 0, 1,2 and 3. At 1 and 12 months after TAVR, LVDD was not associated with KCCQ-OS. Recovery in KCCQ-OS after TAVR was substantial and similar in patients across all severities of LVDD.ConclusionsAlthough LVDD is associated with health status prior to TAVR, patients across all severities of LVDD have similar recovery in health status after TAVR. 相似文献

Objectives
The aim of this study was to compare self-expanding and balloon-expandable transcatheter heart valves (THVs) in large versus small aortic valve annuli.Background
The degree of THV oversizing varies according to annular size, and this can modify the hemodynamic performance of self-expanding and balloon-expandable THVs.Methods
Patients undergoing transcatheter aortic valve replacement in the randomized CHOICE (Comparison of Transcatheter Heart Valves in High Risk Patients With Severe Aortic Stenosis: Medtronic CoreValve vs Edwards SAPIEN XT) trial (CoreValve [CV], n = 120; SAPIEN XT [SXT], n = 121) and the nonrandomized CHOICE-Extend registry (Evolut R [ER], n = 100; SAPIEN 3 [S3], n = 334) were compared for THV performance by echocardiography (in all patients) and by cardiac magnetic resonance imaging (MRI) regurgitant fraction (RF) (in a subgroup of patients). Patients were stratified according to aortic valve annular mean diameter into those with large (>23 mm) or small (≤23 mm) annuli.Results
THV percentage oversizing was 19.1 ± 6.4% with the CV, 11.4 ± 7.0% with the SXT, 18.8 ± 4.8% with the ER, and 3.7 ± 5.5% with the S3. Transvalvular mean pressure gradient was lower with the CV and ER than with the SXT and S3 in both the large and small annulus groups. In the randomized CHOICE trial, moderate to severe prosthetic valve regurgitation (PVR) was more with the CV than the SXT in large annuli (15.1% vs. 0.0%; p = 0.002; MRI RF: 10.5 ± 10.2% vs. 4.4 ± 4.5%; p = 0.036) but not in small annuli (0.0% vs. 5.7%; p = 0.50; MRI RF: 4.0 ± 4.1% vs. 4.0 ± 3.4%; p = 0.98). In the CHOICE-Extend registry, moderate to severe PVR occurred in 2 patients, and any PVR was not significantly different between the ER and the S3 in large (41.7% vs. 32.5%; p = 0.24) or small (47.1% vs. 43.8%; p = 0.84) annuli. MRI RF was not different in large annuli (5.0 ± 3.8% vs. 5.0 ± 6.1%; p = 0.99) but was significantly lower with the ER than the S3 in small annuli (2.9 ± 2.3% vs. 4.8 ± 3.7%; p = 0.023). On multivariate analysis, transcatheter aortic valve replacement with the ER in small annuli was associated with a lower rate of prosthesis-patient mismatch than with the S3, with no increased risk for PVR.Conclusions
Older-generation balloon-expandable THVs were associated with less PVR than self-expanding THVs in patients with large but not small annuli. The next-generation self-expanding THV has improved sealing in patients with large annuli and may have potential advantages in patients with small annuli. 相似文献19.

Background
It is unclear whether the Ross procedure offers superior survival compared with mechanical aortic valve replacement (AVR).Objectives
This study evaluated experience and compared long-term survival between the Ross procedure and mechanical AVR.Methods
Between 1992 and 2016, a total of 392 Ross procedures were performed. These were compared with 1,928 isolated mechanical AVRs performed during the same time period as identified using the University of Melbourne and Australia and New Zealand Society of Cardiac and Thoracic Surgeons’ Cardiac Surgery Databases. Only patients between 18 and 65 years of age were included. Propensity-score matching was performed for risk adjustment.Results
Ross procedure patients were younger, and had fewer cardiovascular risk factors. The Ross procedure was associated with longer cardiopulmonary bypass and aortic cross-clamp times. Thirty-day mortality was similar (Ross, 0.3%; mechanical, 0.8%; p = 0.5). Ross procedure patients experienced superior unadjusted long-term survival at 20 years (Ross, 95%; mechanical, 68%; p < 0.001). Multivariable analysis showed the Ross procedure to be associated with a reduced risk of late mortality (hazard ratio: 0.34; 95% confidence internal: 0.17 to 0.67; p < 0.001). Among 275 propensity-score matched pairs, Ross procedure patients had superior survival at 20 years (Ross, 94%; mechanical, 84%; p = 0.018).Conclusions
In this Australian, propensity-score matched study, the Ross procedure was associated with better long-term survival compared with mechanical AVR. In younger patients, with a long life expectancy, the Ross procedure should be considered in centers with sufficient expertise. 相似文献20.
