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

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4.

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5.

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.

Device embolization is a rare complication of transcatheter structural heart interventions. Although the majority of device embolizations can be treated in a semielective manner, some are life threatening and require prompt intervention. Awareness of this potential complication, and knowledge of retrieval tools and techniques are essential to the structural interventionalist. This paper offers a succinct review of the incidence, and outcomes of device embolization during common structural heart interventions. It also provides an overview of the essential component of the “percutaneous retrieval toolbox” and suggests a systematic algorithmic approach for the management of device embolization. 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11.

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12.

Objectives
This study aimed to assess the long-term risk of death and atherosclerotic cardiovascular disease (ASCVD) outcomes, including stroke, in a real-world cohort that underwent coronary artery calcium (CAC) scoring.Background
Large-scale, long-term studies assessing the independent relationship of CAC for prediction of ASCVD events, to include stroke, in young, low-risk patients are uncommon outside of the clinical trial setting.Methods
A total of 23,637 consecutive subjects without ASCVD who underwent CAC scoring from 1997 to 2009 were studied. Subjects were assessed for myocardial infarction (MI), stroke, major adverse cardiovascular events (MACE) (e.g., MI, stroke, or cardiovascular death), and all-cause mortality. Outcomes were extracted from the Military Data Repository and the National Death Index and assessed using Cox proportional hazards models, controlling for baseline risk factors, atrial fibrillation, and competing mortality.Results
Patients (mean age 50.0 ± 8.5 years) were followed over a median of 11.4 years. The relative adjusted subhazard ratio (aSHR) for CAC 1 to 100, 101 to 400, and >400 was 2.2, 3.8, and 5.9 for MI; 1.2, 1.4, and 1.9 for stroke; 1.4, 2.0, and 2.8 for MACE; and 1.2, 1.5 and 2.1 for death (p < 0.0001). The addition of CAC score to risk factors significantly improved the prognostic accuracy for all outcomes by the likelihood ratio test. Area under the curve increased from 0.658 to 0.738 for MI, 0.703 to 0.704 for stroke, 0.685 to 0.705 for MACE, and 0.759 to 0.767 for mortality. Among subjects without traditional risk factors (n = 6,208; mean age 43.8 ± 4.4 years), the presence of any CAC (>0; n = 848) was associated with an increased risk of MACE (aSHR: 1.67; 95% confidence interval: 1.16 to 2.39).Conclusions
CAC scoring significantly improved long-term prognostic accuracy for MACE events and mortality, irrespective of age and risk factors. These results support CAC screening for improving individual ASCVD risk assessment and prevention in low-risk, young adults. 相似文献13.

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17.

Objectives
The purpose of this prospective study was to evaluate the acute success and complication rates of combined transradial and transpedal access for femoral artery intervention.Background
Improved equipment and techniques have resulted in transition from transfemoral to transradial access for intervention of superficial femoral artery.Methods
Between 2014 and 2016, clinical and angiographic data from 145 consecutive patients with symptomatic superficial femoral stenosis, treated via primary radial access using the 6-F SheathLess Eaucath PV guiding catheter were evaluated in a pilot study. Secondary access was achieved through the pedal or popliteal artery. The primary endpoints were major adverse events, target lesion revascularization, and rates of major and minor access-site complications. Secondary endpoints included angiographic outcome, procedural factors, crossover rate to femoral access site, and duration of hospitalization.Results
Technical success was achieved in 138 patients (95.2%). Combined radial and pedal access was obtained in 22 patients (15.1%). The crossover rate to a femoral access site was 2%. Stent implantation was necessary in 23.4% of patients. Chronic total occlusion recanalization was performed in 63 patients, with a 90.4% technical success rate. The mean contrast consumption, radiation dose, and procedure time were 112.9 ml (101.8 to 123.9 ml), 21.84 Gy/cm2 (9.95 to 33.72 Gy/cm2), and 34.9 min (31.02 to 38.77 min), respectively. The cumulative rate of access-site complications was 4.8% (0% major, 4.8% minor). The cumulative incidence rates of major adverse events at 3 and 12 months follow-up was 8.3% and 19.2%. The cumulative incidence rates of death at 3- and 12-month follow-up were 2.8% and 5.6%.Conclusions
Femoral artery intervention can be safely and effectively performed using radial and pedal access with acceptable morbidity and a high technical success rate. 相似文献18.

Background
Atherosclerotic plaque characteristics may affect downstream myocardial perfusion, as well as coronary lesion severity.Objectives
This study sought to evaluate the association between quantitative plaque burden and plaque morphology obtained using coronary computed tomography angiography (CTA) and quantitative myocardial perfusion obtained using [15O]H2O positron emission tomography (PET), as well as fractional flow reserve (FFR) derived invasively.Methods
Two hundred eight patients (63% men; age 58 ± 8.7 years) with suspected coronary artery disease were prospectively included. All patients underwent 256-slice coronary CTA, [15O]H2O PET, and invasive FFR measurements. Coronary CTA-derived plaque burden and morphology were assessed using commercially available software and compared with PET perfusion and FFR.Results
Atherosclerotic plaques were present in 179 patients (86%) and 415 of 610 (68%) evaluable coronary arteries. On a per-vessel basis, traditional coronary plaque burden indexes, such as plaque length and volume, minimal lumen area, and stenosis percentage, were significantly associated with impaired hyperemic myocardial blood flow (MBF) and FFR. In addition, morphological features, such as partially calcified plaques, positive remodeling (PR), and low attenuation plaque, displayed a negative impact on hyperemic MBF and FFR. Multivariable analysis revealed that the morphological feature of PR was independently related to impaired hyperemic MBF as well as an unfavorable FFR (p = 0.004 and p = 0.007, respectively), next to stenosis percentage (p = 0.001 and p < 0.001, respectively) and noncalcified plaque volume (p < 0.001 and p = 0.010, respectively).Conclusions
PR and noncalcified plaque volume are associated with detrimental downstream hyperemic myocardial perfusion and FFR, independent of lesion severity. 相似文献20.

Tricuspid valve abnormalities in congenital heart disease comprise a wide spectrum, with the most common being Ebstein anomaly and tricuspid valve dysplasia. Tricuspid valve dysfunction may also be secondary to other types of congenital heart disease, including functional tricuspid regurgitation seen in right heart volume overload conditions, such as atrial septal defect and repaired tetralogy of Fallot with severe pulmonary valve regurgitation. Congenitally corrected transposition and Mustard and Senning procedures maintain the right ventricle as the systemic ventricle, and the tricuspid valve is subject to unique hemodynamic stress not typically seen in normal circulation. Surgical treatment of tricuspid valve disease remains the mainstay of therapy; primary catheter-based interventions are uncommon. However, once a tricuspid valve has been replaced with a bioprosthesis, the patient may be a candidate for tricuspid valve-in-valve catheter-based replacement. 相似文献
