Background Differences in systemic venous flow dynamics and energy losses exist in various Fontan-type procedures, which may affect atrial and ventricular filling. The aim of this study was to test…
Background Response to cardiac resynchronization therapy is variable. The aim of this study was to test the hypothesis that left ventricular (LV) lead position in proximity to myocardial scar is…
Background Previous studies have reported abnormal left ventricular (LV) contraction in patients with mitral stenosis (MS). The aim of this study was to explore the serial changes in LV mechanics…
Background The optimal timing of mitral valve repair (MVr) in patients with chronic severe degenerative mitral regurgitation (MR) remains controversial and is broadly based on either measurable loss of systolic…
Background Diagnostic errors are unwanted clinical events that place patients at risk for injury. The authors have previously reported that a majority of congenital echocardiography errors have clinical impacts and,…
Background Increased left ventricular (LV) dimensions are an indication for surgery in patients with asymptomatic mitral regurgitation, but M-mode or two-dimensional measurements have known limitations. The aim of this study…
At an early morning hour at the start of a busy work day, a dozen individuals position themselves at conference room tables in front of a projector and screen. After…
Background The submitral apparatus maintains annular-papillary continuity and myocardial geometry. In mitral valve prolapse (MVP), elongated chords and redundant leaflets can interact at the region of myocardial attachment, leading to…
Background Initial experience with the new St. Jude Trifecta pericardial aortic stented bioprosthesis shows an excellent resting hemodynamic profile. Little is known about changes in the hemodynamic profile of the…
Background Patient-prosthesis mismatch (PPM) has been reported with a wide range of bioprosthetic valves after aortic valve replacement (AVR) and has been associated with multiple adverse outcomes. The aim of…
