Background —Although defects on intracoronary myocardial contrast echocardiography (MCE) indicate loss of viability after reperfusion, opacified segments may also exhibit persistent dyssynergy. Therefore, we related the intensity and texture of opa

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

Background. Dynamic changes of myocardial blood flow have been observed after reperfusion of an occluded coronary artery. MCE performed by intracoronary contrast injection can provide an estimate of microvascular flow. We hypothesized that MCE perfor

Distension of one side of the heart involves both the strium and the ventricle, and such atrioventricular enlargement encoroaches more on pericardial volume than would ventricular distension alone. The influence of distension of the entire right side

In fifteen prospective patients with aortic stenosis undergoing transseptal cardiac catheterization, dye-dilution and count-based estimates of pulmonary blood volume (PBV) were performed. Three radionuclide methods were evaluated. Two were based on e

To evaluate the relationship between mean pulmonary transit time and peak-to-peak transit time by digital intravenous angiography six dogs were assessed during either isoproterenol or phenylephrine infusion. Acutely anesthetized dogs were instrumente

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
