WebApr 9, 2024 · Left atrial ligation (LAL) of the chick embryonic heart is a model of the hypoplastic left heart syndrome (HLHS) where a purely mechanical intervention without genetic or pharmacological manipulation is employed to initiate cardiac malformation. It is thus a key model for understanding the biomechanical origins of HLHS. However, its … WebSep 10, 2016 · Once fully developed, RV hypertrophy is associated with a sustained increase in right atrial pressure, impaired LV filling, and decreased exercise tolerance. Treatment focuses on pharmacologic therapies to selectively reduce pulmonary vasomotor tone and diuretics to minimize excessive RV dilation.
WebAbstract. BACKGROUND: A characteristic of both clinical and experimental atrial fibrillation (AF) is atrial electric remodeling associated with profound reduction of L-type Ca (2+) current and shortening of the action potential duration. The possibility that microRNAs (miRNAs) may be involved in this process has not been tested. Web1 INTRODUCTION. Estimating right atrial pressure (RAP) is clinically important for diagnosing right-sided congestive heart failure (R-CHF), managing various hemodynamic conditions, and estimating pulmonary artery pressure. 1-3 Ultrasonographic measures of the caudal vena cava and the presence of hepatic venous distension are common surrogates …
WebRest and exercise hemodynamics in a subset of the patient group demonstrated that the exercise pressure gradient between the left (PCWP) and right atrium (central venous pressure [CVP]) reduced from 20 mm Hg to 13 mm Hg, and there was no increase in pulmonary pressures or pulmonary vascular resistance (PVR). WebThe left atrial reduction plasty was completed on the right side by excising all redundant tissue between the right-sided pulmonary veins and the interatrial septum, extending down below the inferior vena cava. Cross-clamp and cardiopulmonary bypass times were 153 and 189 minutes, respectively.
