Effects of acute hemodynamic alterations on pulmonic valve motion. Experimental and clinical echocardiographic studies.
The purpose of this study was to assess the effects of acute alterations of the pulmonary circulation on the pulmonic valve echocardiogram. We measured the pulmonic valve opening velocity (PVOV) and right-sided systolic time intervals (right ventricular preejection period-to-right ventricular ejection time ratio [RPEP/RVET] in 22 open-chest dogs subjected to acute hemodynamic alterations produc...
متن کاملHemodynamic Effects of Valvulotomy in Pulmonic Stenosis By PAUL
Seven patients with mild to moderate pulmonic stenosis with intact ventricular septum were subjected to cardiac catheterization before and from 4 to 18 months after pulmonary valvulotomy. Despite uniform clinical improvement, remarkably slight changes were observed, following surgery, in right ventricular pressure, pulmonary artery pressure, pulmonary artery flow, and pulmonary valve area, when...

متن کاملBicuspid Pulmonic Valve and Pulmonary Artery Aneurysm
Bicuspid pulmonary valves and pulmonary artery aneurysms are two rare entities, reported in association, and usually attributed to hemodynamic alterations caused by the bicuspid pulmonary valve. We present magnetic resonance images of a patient with a bicuspid pulmonary valve and pulmonary artery aneurysm, and propose an alternative mechanism for this association, based on recent embryologic st...
