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
The aim of this study was to identify independent correlates of very late scaffold thrombosis (VLST) from an analysis of consecutively treated patients from 15 multicenter studies.Background
Recent analyses suggest an increased risk for VLST with the Absorb Bioresorbable Vascular Scaffold compared with drug-eluting stents, but insights as to correlates of risk are limited.Methods
A total of 55 patients were identified with scaffold thrombosis. They were matched 2:1 with control subjects selected randomly from patients without thrombosis from the same study. Quantitative coronary angiography was available for 96.4% of patients. Multiple logistic and Cox regression analysis were used to identify significant independent outcome correlates from 6 pre-specified characteristics.Results
Patients had scaffold thrombosis at a median of 20 months (interquartile range: 17 to 27 months). Control subjects were followed for 36 months (interquartile range: 24 to 38 months). For the combined groups, reference vessel diameter (RVD) was 2.84 ± 0.50 mm, scaffold length was 26 ± 16 mm, and post-dilatation was performed in 56%. Univariate correlates of thrombosis were smaller nominal scaffold/RVD ratio (linear p = 0.001; ratio <1.18:1; odds ratio: 7.5; p = 0.002) and larger RVD (linear p = 0.001; >2.72 mm; odds ratio: 3.4; p = 0.001). Post-dilatation at ≥16 atm, post-dilatation balloon/scaffold ratio, final percentage stenosis, and dual antiplatelet therapy were not correlated with VLST. Only scaffold/RVD ratio remained a significant independent correlate of VLST (p = 0.001), as smaller ratio was correlated with RVD (p < 0.001). Post hoc analysis of 8 other potential covariates revealed no other correlates of outcome.Conclusions
In the present analysis, the largest to date of its type, relative scaffold undersizing was the strongest determinant of VLST. Given current understanding of “scaffold dismantling,” this finding likely has ramifications for all bioresorbable scaffolds. 相似文献3.

Objectives
This study sought to perform a prospective head-to-head comparison of the predictive value of clinical risk factors and a variety of cardiac imaging modalities including coronary artery calcium score (CACS), coronary computed tomography angiography (CTA), single-photon emission computed tomography (SPECT), and invasive coronary angiography (ICA) on major adverse cardiac events (MACE) and all-cause mortality in kidney transplantation candidates.Background
Current guidelines recommend screening for coronary artery disease in kidney transplantation candidates. Furthermore, noninvasive stress imaging is recommended in current guidelines, despite its low diagnostic accuracy and uncertain prognostic value.Methods
The study prospectively evaluated 154 patients referred for kidney transplantation. All patients underwent CACS, coronary CTA, SPECT, and ICA testing. The clinical endpoints were extracted from patients’ interviews, patients’ records, and registries.Results
The mean follow-up time was 3.7 years. In total, 27 (17.5%) patients experienced MACE, and 31 (20.1%) patients died during follow-up. In a time-to-event analysis, both risk factors and CACS significantly predicted death, but only CACS predicted MACE. Combining risk factors with CACS identified a very-low-risk cohort with a MACE event rate of 2.1%, and a 1.0% mortality rate per year. Of the diagnostic modalities, coronary CTA and ICA significantly predicted MACE, but only coronary CTA predicted death. In contrast, SPECT predicted neither MACE nor death.Conclusions
Compared with traditional risk factors and other cardiac imaging modalities, CACS and coronary CTA seem superior for risk stratification in kidney transplant candidates. Applying a combination of risk factors and CACS and subsequently coronary CTA seems to be the most appropriate strategy.

Background
The clinical outcomes of noncompaction cardiomyopathy (NCCM) range from asymptomatic to heart failure, arrhythmias, and sudden cardiac death. Genetics play an important role in NCCM.Objectives
This study investigated the correlations among genetics, clinical features, and outcomes in adults and children diagnosed with NCCM.Methods
A retrospective multicenter study from 4 cardiogenetic centers in the Netherlands classified 327 unrelated NCCM patients into 3 categories: 1) genetic, with a mutation in 32% (81 adults; 23 children) of patients; 2) probably genetic, familial cardiomyopathy without a mutation in 16% (45 adults; 8 children) of patients; or 3) sporadic, no family history, without mutation in 52% (149 adults; 21 children) of patients. Clinical features and major adverse cardiac events (MACE) during follow-up were compared across the children and adults.Results
MYH7, MYBPC3, and TTN mutations were the most common mutations (71%) found in genetic NCCM. The risk of having reduced left ventricular (LV) systolic dysfunction was higher for genetic patients compared with the probably genetic and sporadic cases (p = 0.024), with the highest risk in patients with multiple mutations and TTN mutations. Mutations were more frequent in children (p = 0.04) and were associated with MACE (p = 0.025). Adults were more likely to have sporadic NCCM. High risk for cardiac events in children and adults was related to LV systolic dysfunction in mutation carriers, but not in sporadic cases. Patients with MYH7 mutations had low risk for MACE (p = 0.03).Conclusions
NCCM is a heterogeneous condition, and genetic stratification has a role in clinical care. Distinguishing genetic from nongenetic NCCM complements prediction of outcome and may lead to management and follow-up tailored to genetic status. 相似文献6.

Background
Individuals with coronary heart disease (CHD) are recommended to be physically active and to maintain a healthy weight. There is a lack of data on how long-term changes in body mass index (BMI) and physical activity (PA) relate to mortality in this population.Objectives
This study sought to determine the associations among changes in BMI, PA, and mortality in individuals with CHD.Methods
The authors studied 3,307 individuals (1,038 women) with CHD from the HUNT (Nord-Trøndelag Health Study) with examinations in 1985, 1996, and 2007, followed until the end of 2014. They calculated the hazard ratio (HR) for all-cause and cardiovascular disease (CVD) mortality according to changes in BMI and PA, and estimated using Cox proportional hazards regression models adjusted for age, smoking, blood pressure, diabetes, alcohol, and self-reported health.Results
There were 1,493 deaths during 30 years of follow-up (55% from CVD, median 15.7 years). Weight loss, classified as change in BMI <–0.10 kg/m2/year, associated with increased all-cause mortality (adjusted HR: 1.30; 95% confidence interval [CI]: 1.12 to 1.50). Weight gain, classified as change in BMI ≥0.10 kg/m2/year, was not associated with increased mortality (adjusted HR: 0.97; 95% CI: 0.87 to 1.09). Weight loss only associated with increased risk in those who were normal weight at baseline (adjusted HR: 1.38; 95% CI: 1.11 to 1.72). There was a lower risk for all-cause mortality in participants who maintained low PA (adjusted HR: 0.81; 95% CI: 0.67 to 0.97) or high PA (adjusted HR: 0.64; 95% CI: 0.50 to 0.83), compared with participants who were inactive over time. CVD mortality associations were similar as for all-cause mortality.Conclusions
The study observed no mortality risk reductions associated with weight loss in individuals with CHD, and reduced mortality risk associated with weight gain in individuals who were normal weight at baseline. Sustained PA, however, was associated with substantial risk reduction. 相似文献7.

Background
Blood lipids are established risk factors for myocardial infarction (MI), but uncertainty persists about the relevance of lipids, lipoprotein particles, and circulating metabolites for MI and stroke subtypes.Objectives
This study sought to investigate the associations of plasma metabolic markers with risks of incident MI, ischemic stroke (IS), and intracerebral hemorrhage (ICH).Methods
In a nested case-control study (912 MI, 1,146 IS, and 1,138 ICH cases, and 1,466 common control subjects) 30 to 79 years of age in China Kadoorie Biobank, nuclear magnetic resonance spectroscopy measured 225 metabolic markers in baseline plasma samples. Logistic regression was used to estimate adjusted odds ratios (ORs) for a 1-SD higher metabolic marker.Results
Very low-, intermediate-, and low-density lipoprotein particles were positively associated with MI and IS. High-density lipoprotein (HDL) particles were inversely associated with MI apart from small HDL. In contrast, no lipoprotein particles were associated with ICH. Cholesterol in large HDL was inversely associated with MI and IS (OR: 0.79 and 0.88, respectively), whereas cholesterol in small HDL was not (OR: 0.99 and 1.06, respectively). Triglycerides within all lipoproteins, including most HDL particles, were positively associated with MI, with a similar pattern for IS. Glycoprotein acetyls, ketone bodies, glucose, and docosahexaenoic acid were associated with all 3 diseases. The 225 metabolic markers showed concordant associations between MI and IS, but not with ICH.Conclusions
Lipoproteins and lipids showed similar associations with MI and IS, but not with ICH. Within HDL particles, cholesterol concentrations were inversely associated, whereas triglyceride concentrations were positively associated with MI. Glycoprotein acetyls and several non–lipid-related metabolites associated with all 3 diseases. 相似文献9.

Background
Proenkephalin A (PENK) and its receptors are widely distributed. Enkephalins are cardiodepressive and difficult to measure directly. PENK is a stable surrogate analyte of labile enkephalins that is correlated inversely with renal function. Cardiorenal syndrome is common in acute heart failure (HF) and portends poor prognosis.Objectives
This study assessed the prognostic value of PENK in acute HF, by identifying levels that may be useful in clinical decisions, and evaluated its utility for predicting cardiorenal syndrome.Methods
This multicenter study measured PENK in 1,908 patients with acute HF (1,186 male; mean age 75.66 ± 11.74 years). The primary endpoint was 1-year all-cause mortality; secondary endpoints were in-hospital mortality, all-cause mortality or HF rehospitalization within 1 year, and in-hospital worsening renal function, defined as a rise in plasma creatinine ≥26.5 μmol/l or 50% higher than the admission value within 5 days of presentation.Results
During 1-year follow-up, 518 patients died. Measures of renal function were the major determinants of PENK levels. PENK independently predicted worsening renal function (odds ratio: 1.58; 95% confidence interval [CI]: 1.24 to 2.00; p < 0.0005) with a model receiver-operating characteristic area of 0.69. PENK was associated with the degree of worsening renal function. Multivariable Cox regression models showed that PENK level was an independent predictor of 1-year mortality (p < 0.0005) and 1-year death and/or HF (hazard ratio: 1.27; 95% CI: 1.10 to 1.45; p = 0.001). PENK levels independently predicted outcomes at 3 or 6 months and were independent predictors of in-hospital mortality, predominantly down-classifying risk in survivors when added to clinical scores; levels <133.3 pmol/l and >211.3 pmol/l detected low-risk and high-risk patients, respectively.Conclusions
PENK levels reflect cardiorenal status in acute HF and are prognostic for worsening renal function and in-hospital mortality as well as mortality during follow-up. 相似文献10.

Objectives
The aims of this registry were to determine the incidence, predictors, and prognostic value of periprocedural acute kidney injury (AKI) after left atrial appendage closure (LAAC).Background
No data exist on the occurrence of AKI after LAAC.Methods
A total of 355 patients undergoing LAAC were included in the study. AKI was defined as an absolute or a relative increase in serum creatinine of >0.3 mg/dl or ≥50%, respectively, after the procedure or the need for hemodialysis during index hospitalization.Results
The incidence of AKI was 9%, and patients with worse baseline renal function were at higher risk for developing AKI (odds ratio: 1.32; 95% confidence interval [CI]: 1.09 to 1.61; p = 0.004 for each 10 ml/min decrease in glomerular filtration rate). In-hospital bleeding events occurred more frequently in the AKI group (5.3% vs. 15.6%; p = 0.037). After a median follow-up period of 18 months, patients in the AKI group had higher mortality (hazard ratio [HR]: 2.59; 95% CI: 1.36 to 4.92; p = 0.004), more embolic events (HR: 6.14; 95% CI: 2.23 to 16.92; p = 0.001) and major bleeding events (HR: 2.36; 95% CI: 0.89 to 6.24; p = 0.083). The occurrence of AKI was an independent predictor of midterm mortality (HR: 2.00; 95% CI: 1.02 to 3.91; p = 0.044).Conclusions
The occurrence of AKI was relatively frequent following LAAC, and patients with lower renal glomerular filtration rates were at high risk for developing this complication. AKI identified a group of patients with worse midterm outcomes, highlighting the importance of further preventive strategies in this population. 相似文献11.

Objectives
The authors sought to determine the clinical characteristics and in-hospital survival of women presenting with acute myocardial infarction (AMI) and spontaneous coronary artery dissection (SCAD).Background
The clinical presentation and in-hospital survival of women with AMI and SCAD remains unclear.Methods
The National Inpatient Sample (2009 to 2014) was queried for all women with a primary diagnosis of AMI and concomitant SCAD. Iatrogenic coronary dissection was excluded. The main outcome was in-hospital mortality. Propensity score matching and multivariable logistic regression analyses were performed.Results
Among 752,352 eligible women with AMI, 7,347 had a SCAD diagnosis. Women with SCAD were younger (61.7 vs. 67.1 years of age) with less comorbidity. SCAD was associated with higher incidence of in-hospital mortality (6.8% vs. 3.4%). In SCAD patients, a decrease in in-hospital mortality was evident with time (11.4% in 2009 vs. 5.0% in 2014) and concurred with less percutaneous coronary intervention (PCI) (82.5% vs. 69.1%). Propensity score yielded 7,332 SCAD and 14,352 patients without SCAD. The odds ratio (OR) of in-hospital mortality remained higher with SCAD after propensity matching (OR: 1.87, 95% confidence interval [CI]: 1.65 to 2.11) and on multivariable regression analyses (OR: 2.41, 95% CI: 2.07 to 2.80). PCI was associated with higher mortality in SCAD patients presenting with non–ST-segment elevation myocardial infarction (OR: 2.01; 95% CI: 1.00 to 4.47), but not with STEMI (OR: 0.62; 95% CI: 0.41 to 0.96).Conclusions
Women presenting with AMI and SCAD appear to be at higher risk of in-hospital mortality. Lower rates of PCI were associated with improved survival, with evidence of worse outcomes when PCI was performed for SCAD in the setting of non with ST-segment elevation myocardial infarction. 相似文献12.

Background
In the American College of Cardiology/American Heart Association guidelines, patients are considered to have true-severe stenosis when the mean gradient (MG) is ≥40 mm Hg with an aortic valve area (AVA) ≤1 cm2 during dobutamine stress echocardiography (DSE). However, these criteria have not been previously validated.Objectives
The aim of this study was to assess the value of these criteria to predict the presence of true-severe AS and the occurrence of death in patients with low-flow, low-gradient aortic stenosis (LF-LG AS).Methods
One hundred eighty-six patients with low left ventricular ejection fraction (LVEF) LF-LG AS were prospectively recruited and underwent DSE, with measurement of the MG, AVA, and the projected AVA (AVAProj), which is an estimate of the AVA at a standardized normal flow rate. Severity of AS was independently corroborated by macroscopic evaluation of the valve at the time of valve replacement in 54 patients, by measurement of the aortic valve calcium by computed tomography in 25 patients, and by both methods in 8 patients. According to these assessments, 50 of 87 (57%) patients in the study cohort had true-severe stenosis.Results
Peak stress MG ≥40 mm Hg, peak stress AVA ≤1 cm2, and the combination of peak stress MG ≥40 mm Hg and peak stress AVA ≤1 cm2 correctly classified AS severity in 48%, 60%, and 47% of patients, respectively, whereas AVAProj ≤1 cm2 was better than all the previous markers (p < 0.007), with 70% correct classification. Among the subset of 88 patients managed conservatively (47% of the cohort), 52 died during a follow-up of 2.8 ± 2.5 years. After adjustment for age, sex, functional capacity, chronic kidney failure, and peak stress LVEF, peak stress MG and AVA were not predictors of mortality in this subset. In contrast, AVAProj ≤1 cm2 was a strong predictor of mortality under medical management (hazard ratio: 3.65; p = 0.0003).Conclusions
In patients with low LVEF LF-LG AS, the DSE criteria of a peak stress MG ≥40 mm Hg, or the composite of a peak stress MG ≥40 mm Hg and a peak stress AVA ≤1 cm2 proposed in the guidelines to identify true-severe AS and recommend valve replacement, have limited value to predict actual stenosis severity and outcomes. In contrast, AVAProj better distinguishes true-severe AS from pseudo-severe AS and is strongly associated with mortality in patients under conservative management.

Lemierre's syndrome is a rare and severe sepsis that can rapidly lead to a life-threatening condition in the absence of early management. This syndrome described at the beginning of the 20th century combines oropharyngeal infection complicated with septic thrombosis of the internal jugular vein and septic emboli predominantly pulmonary. Fusobacterium necrophorum, anaerobic germ, Gram negative bacillus is the main germ in this “necrobacillosis”. The diagnosis is should be confirmed precociously with cervicothoracic CT-scan, reference exam, and bacteriological examinations (especially in atypical forms). Its management consists of an emergency antibiotic treatment, combining a third-generation cephalosporin or a betalactam with metronidazole, anticoagulant therapy to be reserved for high-risk situations related to thrombosis. Surgical treatment may be required. 相似文献

Objectives
The aim of this study was to evaluate temporal trends in characteristics and outcomes among patients referred for invasive coronary procedures within a national health care system for veterans.Background
Coronary angiography and percutaneous coronary intervention remain instrumental diagnostic and therapeutic interventions for coronary artery disease.Methods
All coronary angiographic studies and interventions performed in U.S. Department of Veterans Affairs cardiac catheterization laboratories for fiscal years 2009 through 2015 were identified. The demographic characteristics and management of these patients were stratified by time. Clinical outcomes including readmission (30-day) and mortality were assessed across years.Results
From 2009 to 2015, 194,476 coronary angiographic examinations and 85,024 interventions were performed at Veterans Affairs facilities. The median numbers of angiographic studies (p = 0.81) and interventions (p = 0.22) remained constant over time. Patients undergoing these procedures were progressively older, with more comorbidities, as the proportion classified as having high Framingham risk significantly increased among those undergoing angiography (from 20% to 25%; p < 0.001) and intervention (from 24% to 32%; p < 0.001). Similarly, the median National Cardiovascular Data Registry CathPCI risk score increased for diagnostic (from 14 to 15; p = 0.005) and interventional (from 14 to 18; p = 0.002) procedures. Post-procedural medical management was unchanged over time, although there was increasing adoption of transradial access for diagnostic (from 6% to 36%; p < 0.001) and interventional (from 5% to 32%; p < 0.001) procedures. Complications and clinical outcomes also remained constant, with a trend toward a reduction in the adjusted hazard ratio for percutaneous coronary intervention mortality (hazard ratio: 0.983; 95% confidence interval: 0.967 to 1.000).Conclusions
Veterans undergoing invasive coronary procedures have had increasing medical complexity over time, without attendant increases in mortality among those receiving interventions. As the Department of Veterans Affairs moves toward a mix of integrated and community-based care, it will be important to account for these demographic shifts so that quality can be maintained. 相似文献16.

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
