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,…
Background Left ventricular outflow tract (LVOT) geometry is variable and often elliptical, which can affect aortic valve area calculation in patients with aortic stenosis (AS). Specific differences in LVOT geometry…
Meryl S. Cohen, MD, FASE, FACC, FAHA For over two decades, the Pediatric and Congenital Heart Disease Council of the American Society of Echocardiography has had a long history of…
Patrick D. Coon, RCCS, RDCS, FASE • Congenital heart disease (CHD) affects about 1% of live births, or about 40,000 babies, each year in the United States of America. •…
Background In patients with hypertrophic cardiomyopathy (HCM), akinetic apical aneurysms are associated with ventricular tachycardia, heart failure, apical thrombus, and mortality. The cause of apical aneurysms remains unresolved, and there…
