Right ventricular Hemodynamic Alteration after Pulmonary Valve Replacement in Children with Congenital Heart Disease
Introduction: In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...

Background: We assessed different systolic cardiac indices to describe left and right ventricular dysfunction in cirrhotic patients before liver transplantation. Methods: In this case-control study, eighty-one consecutive individuals with the confirmed hepatic cirrhosis and candidate for liver transplantation in the Imam Khomeini Hospital between March 2008 and March 2010 were selected. T...
متن کاملThe relationship of afterload to ejection performance in chronic mitral regurgitation.
Simultaneous left ventricular micromanometry and biplane cineangiography were performed in nine control subjects (group 1), 14 patients with chronic mitral regurgitation and an ejection fraction of 57% or greater (group 2), and 13 patients with mitral regurgitation and an ejection fraction of less than 57% (group 3). End-diastolic volume index was increased in both groups with mitral regurgitat...
متن کاملHemodynamic predictors of outcome in patients undergoing valve replacement.
The afterload-corrected end-systolic volume index (ratio of end-systolic stress to end-systolic volume index [ESS/ESVI]) was previously useful in predicting outcome in patients with mitral regurgitation undergoing valve replacement. Therefore we tested ESS/ESVI together with standard hemodynamic variables as possible predictors of outcome in 39 patients with various valvular lesions who underwe...
متن کاملEvaluation of left ventricular ejection fraction as a measure of pump performance in patients with chronic mitral regurgitation.
Left ventricular (LV) ejection fraction may not adequately detect a reduction in LV systolic performance resulting from chronic mitral regurgitation (MR), due to ventricular unloading into the low-impedance left atrium. To determine whether LV ejection fraction sufficiently gauges myocardial function in MR, nine patients were studied using micromanometer-measured LV pressures and biplane cineve...
