Abstract Background Von Willebrand factor (VWF) elevation correlates with the left atrial blood stasis in nonvalvular atrial fibrillation (NVAF). However, the long-term impact of elevated VWF in patients with NVAF is not well established. Methods To assess the impact of VWF and a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS13) in conjunction with echocardiographic measures of left atrium blood stasis on clinical outcomes, 414 NVAF prospectively recruite...

Ebstein anomaly has a breadth of presentations, including "typical" and "atypical," and can be confused with congenital tricuspid dysplasia. We summarize how to differentiate within this spectrum of disease. Both typical and atypical Ebstein have an underlying failure of delamination, but atypical Ebstein does not have ≥8mm/m2 apical septal leaflet displacement. In congenital tricuspid dysplasia, delamination is normal, while the leaflets and subvalvar apparatus are abnormal. To summarize, the s...

The COVID-19, due to SARS-CoV-2, has uncovered many real-world issues when it comes to healthcare management and has led to a widespread mortality. Observations thus far from the reports of COVID-19 have indicated that certain risk groups for example, those with pre-existing cardiovascular (CV) disease, hypertension, diabetes, chronic kidney disease and tobacco use are prone to disease development and specifically development of severe disease and possible fatality. It is increasingly evident th...

Abstract Objectives The purpose of this retrospective cohort study was to compare remodeling of left ventricular (LV) structure and function after transcatheter stent therapy with remodeling of LV structure and function after surgical therapy for COA. Background Transcatheter stent therapy is as effective as surgery in producing acute hemodynamic improvement in patients with coarctation of aorta (COA). However, LV remodeling after transcatheter COA intervention has not been systematically invest...

5o year old female patient with a medical history of hypertension presented to the clinic with chest pain, palpitations, and dyspnea on exertion of 2 years duration. Extensive workup in search of the culprit etiology of her chest pain revealed a challenging combination of an anomalous left anterior descending artery with myocardial bridging and endothelial dysfunction. She was treated medically with long acting nitrates, L-arginine and calcium channel blockers, and remains asymptomatic after 12 ...

Background Patients with Eisenmenger syndrome are known to have a high incidence of sudden cardiac death (SCD), yet the underlying causes are not well understood. We sought to define the predictors of SCD in this population. Methods and Results A retrospective analysis of all patients with Eisenmenger syndrome from 2 large tertiary referral centers was performed. ECGs, prolonged ambulatory recordings, echocardiograms, and clinical histories were reviewed; and the cause of death was identified. A...

Abstract Background Left heart filling pressures, as measured by pulmonary artery wedge pressure (PAWP), is associated with heart failure related mortality. Because of the prognostic importance of PAWP, several echocardiographic indices have been proposed for noninvasive assessment of PAWP. However, these indices have not been validated in the congenital heart disease population. The purpose of this study was to determine the correlation between echocardiographic indices of PAWP, and the effect ...

Abstract Cardiac magnetic resonance imaging derived right ventricular (RV) volumes are often necessary for optimal timing of pulmonary valve replacement in patients with tetralogy of Fallot (TOF). This practice is based on previous studies that reported preoperative RV volumetric thresholds that predicted postoperative RV remodeling. As a result, pulmonary valve replacements are being performed even in asymptomatic patients based on RV volumetric thresholds that predict complete postoperative RV...
