Right ventricular suction: an important determinant of cardiac performance.
It has long been stated that researchers can be divided into lumpers and splitters. With respect to cardiac physiology, there is a simple appeal in lumping all of the inter-related factors together and assessing global measures of cardiac performance. On the other hand, splitting the cardiac cycle into its individual mechanical properties provides an opportunity to identify specific determinant...
متن کاملThe effects of oral hydralazine on right ventricular end-diastolic pressure in patients with right ventricular failure.
Hydralazine reduces pulmonary vascular resistance in patients with primary and secondary pulmonary hypertension, but the effects on right ventricular function of a change in resistance without a reduction in pulmonary arterial pressure are not known. We evaluated the hemodynamic effects of hydralazine, 50 mg, administered orally every 6 hours for 48 hours in 14 patients with right ventricular f...
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...
متن کاملRight ventricular end-diastolic volume monitoring after cardiac surgery.
INTRODUCTION In the postoperative management of cardiac surgery patients, pulmonary capillary wedge pressure (PCWP) and central venous pressure (CVP) are the most commonly used parameters of preload. However, these pressure parameters are easily affected by ventricular compliance, positive end-expiratory pressure and other factors. The aim of this study was to evaluate whether right ventricular...
متن کاملRight ventricular dysfunction persists following brief right ventricular pressure overload.
OBJECTIVE Acute pulmonary hypertension may cause right ventricular (RV) contractile failure. While it has been assumed that restoration of normal loading conditions after acute pulmonary hypertension is sufficient for complete recovery of RV function, this has not been rigorously examined. The purpose of this study was to test the hypothesis that acute RV pressure overload produces RV contracti...
