Background Recently concluded multicenter studies have shown that none of an array of echocardiographic indicators of ventricular dyssynchrony have enough sensitivity and specificity for predicting response to cardiac resynchronization therapy…
Background The aim of this study was to find the best model to obtain valid and normally distributed Z scores for coronary artery (CA) diameters in a large, heterogeneous population…
Background The reported incidence of atrial fibrillation (AF) occurring during dobutamine stress echocardiography (DSE) ranges from 0.5% to 4%. The aim of this study was to characterize the incidence, risk…
Hypertrophic cardiomyopathy (HCM) is clinically defined by the presence of unexplained left ventricular (LV) hypertrophy in the absence of abnormal loading conditions. Although HCM was once considered a rare disorder…
Background The ideal provocative maneuver in patients with hypertrophic cardiomyopathy (HCM) is a subject of ongoing investigation. Standing is a fundamental activity of daily life. This study examined acquisition of…
Background Echocardiography is the imaging modality of choice for the evaluation of coronary artery (CA) abnormalities in Kawasaki disease. Small series have established high specificity and sensitivity for detecting abnormalities,…
Background Analysis of myocardial deformation from data stored in Digital Imaging and Communications in Medicine format using vendor-independent software may be useful for clinical and research purposes but has not…
Aortic stenosis is becoming an increasing health care problem as the population ages. Surgical aortic valve replacement remains the gold standard but is associated with high mortality and morbidity rates…
Objective The tricuspid annular plane systolic excursion (TAPSE) as an echocardiographic index to assess right ventricular (RV) systolic function has not been investigated thoroughly in pediatric patients and adolescents with…
Background Surgical aortic valve replacement (SAVR) is the definitive proven therapy for patients with severe aortic stenosis who have symptoms or decreased left ventricular (LV) function. The development of transcatheter…
