background: diabetes mellitus is capable of impairing the myocardial function. several studies have documented the influential impact of diabetes mellitus on the left ventricular function. the right ventricular function plays a significant role in the overall myocardial contractility; hence, this study was undertaken to evaluate the effect of diabetes mellitus type ii on the right ventricular f...

The Bernheim syndrome has been a topic of discussion for over a century. It has been reported to be caused by severe rightward movement of the ventricular septum resulting in compression of the right ventricular cavity leading to right-sided heart failure without pulmonary congestion. Hemodynamic findings have been described in a few patients with the so-called Bernheim syndrome. We describe a ...

For characterization of left ventricular function using changes in heart rate, we performed right atrial pacing in 16 patients during right and left heart catheterizations. Hemodynamic data was obtained before pacing (B), during pacing (D), and immediately after (A) the sudden interruption of pacing, for assessment of the consequences of rapid changes in stroke volume. In 10 patients with norma...

Clinical and hemodynamic manifestations of overt right ventricular infarction differ markedly from those that involve injury confined exclusively to the left ventricle. However, the frequency of covert right ventricular infarction and its influence on overall enzymatically estimated infarct size, hemodynamics and prognosis have not been characterized. Accordingly, 249 patients with transmural a...

The exercise hemodynamic values in two groups of patients with repaired tetrad of Fallot (eight patients with some residual pulmonary insufficiency and seven patients without insufficiency) were compared with values in seven patients with trivial pulmonary stenosis who had not been operated on. The patients with tetrad of Fallot underwent surgery after age 8 years and all had a good hemodynamic...

We have identified pericardial effusion by echocardiography in 174 patients. Seventeen had cardiac tamponade which was not always clinically obvious. Right ventricular narrowing or compression, occurring in the minor axis at end diastole and end expiration, to 7 +/- 2 mm or less, was strongly associated with tamponade in patients with effusion. Right ventricular compression and signs of tampona...

Twenty-five patients with septic shock underwent simultaneous radionuclide ventriculography and right heart catheterization to clarify the role of the right ventricle in this syndrome. A depressed right ventricular ejection fraction (less than 38%) was present in 13 patients and was found in patients with elevated cardiac output (4 of 6 patients) and with normal or low cardiac output (9 of 19 p...

Severe hypotension while standing became a problem in a patient after discharge from the hospital following right ventricular myocardial infarction. Hemodynamic studies showed that right ventricular systolic function did not maintain adequate left ventricular preload and that the patient did not compensate for cardiac dysfunction by increasing blood volume. Volume expansion by mineralocorticoid...

BACKGROUND Acute right ventricular overload is associated with high morbidity and mortality clinical situations such as: extensive lung resection, pulmonary thromboembolism, lung transplantation and high altitude pulmonary edema. Some points of its pathophysiology remain unclear. OBJECTIVE To assess the hemodynamic effects of experimental acute right ventricular overload in pigs. METHODS Ri...
