It is unknown if transcatheter aortic valve implantation (TAVI) is a safe alternative to surgical aortic valve replacement (SAVR) in patients <65 years old. Data from the National Inpatient Sample database were utilized. Patients from 2011 to 2015, ages 18 to 64 years old (inclusive) who underwent TAVI and SAVR were included. Patients who underwent SAVR and who also received a concomitant nonaortic valve surgery were excluded. A propensity score analysis was used. A total of 18,970 (528 TAVI and 18,442 SAVR) patients were identified...

Normal pediatric values of three-dimensional (3D) left ventricular (LV) volumes and strain are not well established; moreover, no reports exist of the stress-strain relation and the heart rate-corrected velocity of circumferential fiber shortening (VCFc) based upon 3D imaging in children. Three-dimensional LV datasets were obtained in pediatric patients (≤18 years of age) with structurally normal hearts. Ventricular volumes and strain components (longitudinal, GLS; circumferential, GCS; and 3D strain, 3DS) were analyzed using a commercial 3D speckle-tracking analysis package...

Contrast is a recommended but frequently unused tool in transthoracic echocardiography to improve detection of left ventricular thrombus in patients with ejection fraction (EF) ≤35%. The clinical and economic outcomes of a possible solution (i.e., universal contrast use) remain uncertain. To estimate clinical benefit, cost, and cost-effectiveness of a diagnostic strategy of universal use of contrast (vs no contrast) during echocardiography in patients with reduced EF, we created a decision analytic model using echocardiography sensitivity and specificity for left ventricular thrombus detection from a meta-analysis, as well as survival and cost estimates from published literature...

Percutaneous paravalvular leak (PVL) closure has emerged as a feasible alternative to redo valve surgery. However, comparative data on percutaneous and surgical treatment of PVL are scarce. We performed a systematic review and a meta-analysis of studies on percutaneous and surgical treatments of PVL. Of the 2,267 studies screened, 22 eligible studies were analyzed. Primary end points were technical success, 30-day mortality, stroke, and length of stay. Secondary end points were 1-year mortality, readmission for heart failure, reoperation, and symptomatic improvement at follow-up...

Changes in QRS duration and pattern are regarded to reflect severe ischemia in acute coronary syndromes (ACS), and ventricular conduction blocks (VCBs) are recognized high-risk markers in both ACS and acute heart failure. Our aim was to evaluate the prevalence, temporal evolution, association with clinical and angiographic parameters, and impact on mortality of VCBs in ACS-related cardiogenic shock (CS). Data of 199 patients with ACS-related CS from a prospective multinational cohort were evaluated with electrocardiogram data from baseline and day 3...

Little data are available on the accuracy of phase-contrast magnetic resonance imaging (PC-MRI) velocity mapping in the vicinity of intravascular metal stents other than nitinol stents. Therefore, we sought to determine this accuracy using in vitro experiments. An in vitro flow phantom was used with 3 stent types: (1) 316L stainless steel, (2) nitinol self-expanding, and (3) platinum-iridium. Steady and pulsatile flow was delivered with a magnetic resonance imaging-compatible pump (CardioFlow 5000, Shelley Medical, London, Ontario, Canada)...

Transcatheter valve-in-valve implantation (ViV-TAVI) has evolved as an alternative to redo surgical valve replacement (redo-SAVR) for high-risk patients with aortic bioprosthetic valve (BPV) dysfunction. The differences in procedural success and outcomes in a large number of patients who underwent ViV-TAVI compared with redo-SAVR for aortic BPV dysfunction are not known. We conducted a meta-analysis of the previously reported studies to determine outcomes after ViV-TAVI and redo-SAVR. PubMed, MEDLINE, and Google Scholar databases were searched for studies that reported comparative outcomes of patients who underwent either ViV-TAVI or redo-SAVR...

Penile erection is a hemodynamic process consisting of 2 synchronized components in which the first (active) requires proper vascular endothelium functioning, whereas the second one (passive) is based on a veno-occlusive mechanism. Antihypertensive treatment reduces the passive component, often leading to the development of erectile dysfunction (ED), but lifestyle modifications can improve the sexual functioning. The study aimed to evaluate the association between blood pressure (BP) reduction caused by cardiovascular training and the intensity of ED in men with coronary heart disease...

The diagnosis of acute coronary syndrome (ACS) encompasses ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation ACS (non-STEMI and unstable angina). In recent years, there have been improvements in the rates of death, cardiogenic shock, and recurrent myocardial infarction in patients with ACS, primarily due to the introduction of new pharmacological and interventional therapies, as well as the introduction of and adherence to new treatment guidelines. However, ACS still represents a considerable public health burden...

The prevalence of congenital and acquired heart disease in patients with the Turner syndrome (TS) is based on historic cohorts who underwent imaging before the advent of modern day echocardiography. Recent small studies suggest a higher prevalence of cardiac defects. We reviewed clinical and echocardiographic data on 564 girls and women with TS to assess the prevalence of cardiac defects. Echocardiographic review on a subset of this population was performed to assess for diagnostic limitations of echocardiography in assessing for congenital and acquired defects in this patient cohort...

Cardiac and respiratory function may be impaired in sarcoglycanopathies, a subgroup of muscular dystrophies due to sarcoglycan proteins (α, β, γ, and δ) genes mutations. Management of patients with restrictive respiratory failure mainly relies on home mechanical ventilation (HMV). Little is known about the cardiac effects of prolonged mechanical ventilation in patients with muscular dystrophy and restrictive respiratory insufficiency. We aimed to assess the effects of HMV on cardiac function in sarcoglycanopathies...

Anatomical SYNTAX score (SS1) and SYNTAX score II (SS2) are often utilized to determine the optimal revascularization strategy. Although US veterans have unique characteristics that may affect outcomes after revascularization, the prognostic values of SS1 and SS2 in veterans have not yet been validated. We performed a retrospective analysis of consecutive veteran patients who underwent percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for left main and/or 3-vessel disease from 2009 to 2014...

Conflicting data exist regarding the associations of early repolarization (ER) with electrocardiogram (ECG) and clinical outcomes in blacks. We examined the association of ER defined by J point elevation (JPE) and all-cause mortality, and heart failure (HF) hospitalization in blacks in the Jackson Heart Study (JHS) cohort. We included JHS participants with ECGs from the baseline visit coding JPE and excluded participants with paced rhythms or QRS duration ≥120 ms. We compared the cumulative incidence of 10-year all-cause mortality and 8-year HF hospitalization by presence of JPE ≥0...

It is unclear how age affects rates and causes of unplanned early readmissions after percutaneous coronary intervention (PCI). We analyzed patients in the Nationwide Readmission Database in the United States from 2010 to 2014 and examined the impact of age on readmissions after PCI. The primary outcomes were age-specific 30-day rates and causes of unplanned readmissions. A total of 2,294,345 procedures were analyzed with a 9.6% unplanned readmission rate within 30 days. Unplanned readmissions were 8.1%, 8.1%, 9...
