Physiological consequences of percutaneous pulmonary valve implantation: the different behaviour of volume- and pressure-overloaded ventricles.
AIMS To investigate the early clinical and physiological consequences of relieving chronic right ventricular (RV) volume overload with percutaneous pulmonary valve implantation (PPVI). METHODS AND RESULTS We selected 17 patients (age 21.2 +/- 8.7 years), from a total of 125 who underwent PPVI, because they had important pulmonary regurgitation (PR) [regurgitant fraction > 25% on magnetic reso...
متن کاملPressure overloaded right ventricles: importance of trabeculae in evaluation of RV function by CMR
Background Cardiac magnetic resonance imaging (CMR) is the preferred method to evaluate right ventricular (RV) volumes and ejection fraction. In CMR-volumetry, trabeculae and papillary muscles can be either inor excluded from the blood volume and both methods are used throughout literature. This study aimed to determine the impact of trabeculae and papillary muscles on right ventricular (RV) vo...
متن کاملEffects of Chronic Right Ventricular Volume and Pressure Loading
The effects of chronic right ventricular (RV) distension on left ventricular (LV) funiction were assessed in dogs 3 weeks after pressure and volume loading of the RV lhad been produced by the emplacement of a constricting band around the pulmonary artery and the creation of tricuspid insufficiency. This resulted in ascites, RV hypertrophy and dilatation, an increase in RV end-diastolic pressure...
متن کاملEffect of right ventricular pressure on the end-diastolic left ventricular pressure-volume relationship before and after chronic right ventricular pressure overload in dogs without pericardia.
We studied the effect of chronic right ventricular pressure overload on diastolic ventricular interdependence in dogs without pericardia, instrumented to measure left ventricular pressure, right ventricular pressure, and 3 left ventricular dimensions. We studied 12 dogs before (control) and nine dogs after 6 weeks of pulmonary artery constriction producing systolic right ventricular pressure gr...
