There are limited data showing right ventricular preload increase due to high-flow arteriovenous fistulas (AVFs). This cross-sectional study investigated whether high AVF flow had an impact on right ventricular function in patients undergoing hemodialysis. Sixty-four patients aged between 18 and 85 years who were on routine hemodialysis with >2 hemodialysis sessions per week for at least 3 mont...

BACKGROUND Abnormalities in right ventricular function are known to occur in patients with pulmonary arterial hypertension. OBJECTIVE Test the hypothesis that chronic elevation in pulmonary artery systolic pressure delays mechanical activation of the right ventricle, termed dyssynchrony, and is associated with both symptoms and right ventricular dysfunction. METHODS Fifty-two patients (mean...

Right ventricular function before and during 10 days of mild pressure loading (10 mm Hg increase in mean pulmonary arterial pressure) was compared with right ventricular function in unloaded near-term fetal sheep. Pressure loading did not alter fetal arterial blood gases or vascular pressures. The right ventricular function curve (stroke volume versus mean right atrial pressure) was not signifi...

A 47 year-old female died after mitral valve replacement. Post-cardiopulmonary bypass right ventricle was not able to pump despite good left ventricular contractility. At microscopic examination, diffuse right ventricular fatty infiltration was found. We found no previous report of this pathology in patients with mitral stenosis

OBJECTIVE To investigate the fetal right ventricular diastolic function under the condition of umbilical cord around neck (UCAN), and analyze the changes of the right ventricular propagation velocity (Vp), then discuss the clinical value of the color M-mode echocardiography in the evaluation of fetal ventricular diastolic function quantitatively. PATIENTS AND METHODS All patients enrolled wer...
