Patients with repaired pulmonary stenosis (PS) or tetralogy of Fallot (TOF) both develop pulmonary regurgitation (PR) leading to right ventricular (RV) dilatation and dysfunction. We aimed to characterize differential effects…
Although transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR) are validated in quantitation of mitral regurgitation (MR), discrepancies may occur. This study assesses the agreement between TTE and CMR in…
Endothelin (ET) is involved in the etiopathogenesis of peripheral arterial disease (PAD). We hypothesized that ET antagonism might improve the endothelial function, inflammatory status, and symptoms in PAD. This pilot…
Diffuse myocardial fibrosis is involved in the pathology of nonischemic cardiomyopathy (NIC). Recently, the application of native (noncontrast) myocardial T 1 measurement has been proposed as a method for characterizing…
The relation between the etiology of cardiomyopathy and the function of the right ventricle (RV) has not been well described in the current era of 3-dimensional cardiac imaging. New advances…
Percutaneous mitral valve repair (PMVR) using the MitraClip System is feasible and entails clinical improvement even in patients with high surgical risk and severe functional mitral regurgitation (MR). The aim…
We sought to study the prognostic utility of serum brain natriuretic peptide (BNP) in patients with significant primary mitral regurgitation (MR) and preserved left ventricular (LV) ejection fraction (EF). Consecutive…
Transcatheter aortic valve replacement (TAVR) is a viable option in the treatment of severe aortic stenosis in patients at high risk for surgery. We sought to further investigate outcomes in…
Atrial fibrillation (AF) is common and increases stroke risk and mortality. Many knowledge gaps remain with respect to practice patterns and outcomes. Electronic medical records (EMRs) may serve as powerful…
Takotsubo cardiomyopathy (TC) often occurs after emotional or physical stress. Norepinephrine levels are unusually high in the acute phase, suggesting a hyperadrenergic mechanism. Comparatively little is known about parasympathetic function…
