The present study reports the development and characterization of a murine model of right ventricular dysfunction following graded constriction in the pulmonary artery via microsurgical approaches. To analyze in vivo ventricular function, a technique

To clarify whether impaired left ventricular relaxation elicited by increased afterload is attributable to regional dyssynchrony, we analyzed in dogs simultaneous left ventricular contrast ventriculography and pressure before and during angiotensin I

The influence of the pericardium on right and left ventricular filling was studied using two-dimensional and Doppler echocardiography in 14 open-chest dogs. Doppler echo parameters of filling included early (E) and late (A) velocities and their ratio

Left ventricular regional wall motion was analyzed from angiographic ventriculograms in 51 subjects, 18 of these served as controls, 10 were hypertensive with coronary artery disease, and 23 had a history of hypertension without coronary artery disea

Computer-assisted analysis of percent change in the square root of area in each of 12 consecutive 30-degree, pie-shaped ventricular segments was obtained in 48 normal subjects who underwent cardiac catheterization and left ventriculography. The infor

The purpose of this study was to evaluate a number of equilibrium radionulide methods for analyzing right ventricular size and function, in an attempt to determine if any of a variety of approaches could accurately characterize right ventricular hemo

To evaluate the utility of single and biplane right ventricular (RV) contrast angiograms, we evaluated 25 canine RV casts and 31 cineangiograms performed in patients during standard contrast ventriculograms. Both standard single and biplane formulae

T HE object of this review can conveniently be divided into three major areas: (1) normal physiology, i.e., the role played by the pericardium in cardiac function in the subject without disease of the heart or pericardium; (2) the contribution of the

Verapamil was administered intravenously to 30 open-chest dogs and the electrophysiologic and hemodynamic effects of the drug were correlated with the corresponding plasma concentrations. At concentrations below 152 ng/ml, verapamil prolonged the A-H
