We thank Drs Rai, Cronin, Kluger, and LaSala for their interest in our study and for their thorough discussion of the possible mechanisms for prolonged systolic duration during therapeutic hypothermia….
We enjoyed reading the well-done and timely article by Espinoza et al . regarding the effect of therapeutic hypothermia on left ventricular function in an open-chest, anesthetized, and intubated porcine model….
Background Right ventricular (RV) function is a strong predictor of mortality in pulmonary hypertension (PH), but two-dimensional (2D) echocardiography–derived assessments of RV function that could aid in risk assessment and…
Background Ventricular-arterial stiffening is a part of the aging process that is amplified by various comorbidities. It affects normal cardiovascular reserve and limits exercise capacity. The aim of this study…
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…
