introduction: infective endocarditis (ie) causes serious complications in patients. congenital heart disease (chd) is an important underlying condition in children. case presentation: a 6-year-old girl with ventricular septal defect (vsd) was presented. echocardiography revealed large vegetation in right ventricular outflow tract near the pulmonary valve. the patient showed clinical symptoms of...

Background. Patients with acute ischemic right ventricular dysfunction often develop hemodynamic compromise, yet most manifest spontaneous early clinical improvement and later recovery of global right ventricular performance. This study was designed to delineate the determinants of right ventricular performance following chronic right coronary artery occlusion. Methods and Results. Thrombotic r...

Doppler-derived myocardial performance index (MPI) , defined as the s um of isovolumetric contraction and relaxation durations divided by ejection time, is an easily measured and reproducible index that shows both systolic and diastolic myocardial function. The goal of this study was to define normal values of right ventricular MPI in neonates in the first 48 to 72 hours of life. Fifty-one...
