Background The aim of this study was to investigate the effects of transcatheter aortic valve implantation (TAVI) on left ventricular (LV) hypertrophy and diastolic function in patients with severe aortic…
Background The systemic right ventricle in palliated hypoplastic left heart syndrome (HLHS) has relatively reduced longitudinal compared with circumferential deformation, a pattern of contraction more akin to the normal left…
Background Left ventricular noncompaction (LVNC) is characterized by a two-layered myocardium consisting of a noncompacted inner and a compacted outer layer. The ratio of the thicknesses of these two layers…
Background Ligation of a patent ductus arteriosus (PDA) in preterm infants causes profound hemodynamic changes that can result in low cardiac output syndrome and hypotension. The effect of PDA ligation…
Background Tricuspid annular peak systolic velocity (S′), as an echocardiographic index to assess right ventricular (RV) systolic function, has not been investigated thoroughly in children and young adults with repaired…
Background The effect of the atrial septal defect (ASD) shape on ASD size measurements remains unclear. We assessed the relationships between the stretched balloon diameter (SBD) and the diameters measured…
In 2012, the ASE Education and Research Foundation provided funding for two $1,000 travel grants for attendance at the ASE Scientific Sessions for each of its four councils. This year,…
The American Society of Echocardiography is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians. ASE recognizes courses as supplements to formal training…
Background Mechanisms of mitral valve regurgitation after atrioventricular septal defect repair are unclear. Methods To gain further insight into mitral valve regurgitation, real-time three-dimensional echocardiography was performed in 53 patients…
Background Functional analysis of the right ventricle cannot be reliably evaluated by conventional echocardiography, because of its complex geometry and load dependence of ejection phase indices. The Tei index, dP/dt,…
