Right ventricular non-compaction cardiomyopathy (RVNC) is a genetic heterogeneous cardiomyopathy. Despite the increasing number of RVNC cases, the classification and natural history of this disorder are not completely clear. Also, because the pathogenic non-compaction cannot be easily differentiated from normal trabeculations, it is usually hard to accurately measure the prevalence of RV ...

abstract background: right ventricular myocardial performance index (rvmpi) is a doppler–derived parameter of non-geometrical ventricular function that measures both systolic and diastolic functions of the right ventricle. the aim of this study is to compare prognostic value of rvmpi with global rv function in patients undergoing coronary artery bypass graft (cabg). methods: in a longitudinal s...

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...
