Background Coronary and microvascular blood flow reserve have been established as important predictors of prognosis in patients with cardiovascular disease. The aim of this study was to assess the value…
Background Syndrome X in women is thought to be caused by coronary microvascular dysfunction, the exact site of which is unknown. The aim of this study was to characterize the…
Background The aim of this study was to assess systolic left atrial (LA) reservoir function in patients with mitral stenosis (MS) using two-dimensional (2D) strain (ϵ) and strain rate imaging…
All meanings, we know, depend on the key of interpretation. —George Elliott In this issue of JASE , Lima et al. report that reduced myocardial blood flow (MBF) velocity reserve and…
Background Recent reports indicate that the transapical approach for transcatheter aortic valve replacement may be associated with elevated cardiac enzymes, poor recovery of left ventricular function, and poor outcomes. The…
Background The aim of this study was to estimate geometric errors made by the two-dimensional (2D) transthoracic echocardiographic (TTE) pulsed-wave Doppler flow (PWDF) method in calculating regurgitant volume (RVol) and…
Background Aortic valve replacement is the recommended therapy for patients with severe aortic stenosis who have symptoms or decreased left ventricular (LV) function. Transcatheter aortic valve implantation (TAVI) is a…
Background Developing countries face the dual burden of high rates of cardiovascular disease and barriers in accessing diagnostic and referral programs. The aim of this study was to test the…
Background One of the main challenges for imaging laboratories is demonstrating the quality of their studies. The aim of this study was to determine if echocardiographic training and experience are…
The value of echocardiography for diagnosis, therapy, risk stratification, clinical investigation, and basic research is well established. However, as we enter a period of increased scrutiny on resource utilization, the…
