Right ventricular adaptation to pressure overload
Current Opinion in Critical Care, 2010Pressure overload of the right ventricle results in right ventricular failure and death. Identifying right ventricular dysfunction at less severe stages, which would allow for more effective intervention, has been limited largely due to complex three-dimensional geometry, complex left ventricular/septum interactions, and lack of accepted approaches to ...

Right ventricular pressure and coronary flow
American Journal of Physiology-Legacy Content, 1962A method is described which permitted separate, simultaneous measurement of blood flow in the left and right coronary arteries while the performance of the left or right ventricles was altered. As long as neither ventricle was overdistended and when arterial oxygen tension and pH were constant, blood flow in the right or the left coronary tree was a ...

Ejection pressure and the diastolic left ventricular pressure-volume relation
American Journal of Physiology-Heart and Circulatory Physiology, 1977The influence of ejection pressure (EP) on the left ventricular end-diastolic pressure-volume (P-V) relation was examined in 24 paced, isolated canine hearts. A pressure servo system was used to control EP and monitor ventricular volume. For any given contractile state EP was varied: a) by 10- to 20-mmHg increments and the steady-state P-V response ...

Diastolic Blood Pressure and Left Ventricular Filling
American Journal of Hypertension, 1988Many factors appear to influence diastolic left ventricular (LV) filling, including age, hypertension, and myocardial and coronary disease. Doppler-echocardiography was used to asses the influences of blood pressure (BP) on LV filling in 43 normotensive volunteers aged 12 +/- 0.98 years with heart rates less than or equal to 90 beats/min.

Left Ventricular Filling Pressures in Cardiac Patients†
Journal of the American Geriatrics Society, 1975ABSTRACT Pulmonary artery end‐diastolic pressure (PADP), pulmonary artery wedge pressure (PAWP), and pre‐“a” wave left ventricular diastolic pressure (LVDP) were correlated with post‐“a” wave left ventricular end‐diastolic pressure (LVEDP) in 51 patients with coronary disease and in 43 cardiac patients with non‐coronary disease ...

Left ventricular dimensions and function during right ventricular pressure overload
American Journal of Physiology-Heart and Circulatory Physiology, 1982The effects of right ventricular (RV) pressure overload on left ventricular (LV) function is controversial. Therefore, we examined LV dimensions and shortening after acute and chronic pulmonary artery (PA) constriction in six conscious dogs, preinstrumented with LV and RV catheters, an LV micromanometer, a PA inflatable cuff occluder, and ultrasonic ...

Echocardiographic assessment of left ventricular diastolic pressure
Current Opinion in Critical Care, 2019Purpose of review Knowledge of the left ventricular pressures throughout the cardiac cycle is of considerable assistance in managing a haemodynamically unstable patient. Invasive pressure measurement is the only accurate way to analyze ventricular diastolic pressures but this is not feasible outside the catheterization ...
