Background The strategy for mitral valve (MV) repair has recently focused on the restoration of the submitral apparatus. However, the relationship between geometric changes of the submitral apparatus and the…
Background Advances in fetal echocardiography have improved recognition of congenital heart disease (CHD). Imaging protocols have been developed that predict delivery room (DR) risk and anticipated postnatal level of care…
Background Structural right ventricular (RV) abnormalities are present in a substantial proportion of patients with hypertrophic cardiomyopathy (HCM), but the trigger for RV hypertrophy remains unclear. The aim of this…
Background Right ventricular (RV) failure is a key determinant of mortality in children with pulmonary arterial hypertension (PAH). RV stroke work (RVSW) can be estimated as the product of RV…
Background Anatomic features of obstructive hypertrophic cardiomyopathy are septal hypertrophy, elongated mitral leaflets, and anterior displacement of the papillary muscles. In addition to extended myectomy, the resect-plicate-release operation adds horizontal…
Background Impaired left atrial (LA) deformation is noted in patients with severe primary mitral regurgitation (MR), but its prognostic value is unknown. The aim of this study was to investigate…
Background The aim of the present study was to assess and compare the disease progression of aortic stenosis (AS) subtypes from nonsevere to severe disease on the basis of measures…
Background Echocardiographic calculation of effective orifice area (EOA) after transcatheter aortic valve replacement is integral to the assessment of transcatheter heart valve (THV) function. The aim of this study was…
Background Patients with severe aortic stenosis (AS) are known to have increased left ventricular apical rotation (ApRot) during systole, but its clinical relevance is unknown. The aim of this study was…
Accurate assessment of stenosis severity is crucial for the management of patients with aortic stenosis (AS), and transthoracic echocardiography (TTE) is the primary modality for this purpose. In recent guidelines,…
