Prognostic value of right ventricular myocardial performance index in patients undergoing coronary artery bypass surgery
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 ...
متن کاملPercentage of Left Ventricular Stroke Work Loss
The ratio of the mean systolic transaortic valvular gradient to the mean systolic left ventricular pressure times 100 yields a percentage that represents the portion of left ventricular pressure-volume work per stroke lost because of outflow-tract obstruction. The percentage of the left ventricular stroke work loss and the area of the aortic orifice have been estimated in 49 patients with aorti...
متن کاملquantification of aortic regurgitation severity by left ventricular to right ventricular stroke volume ratio
background: echocardiography is the most common test used for the evaluation of aortic regurgitation (ar). however, the role of echocardiography as an available and inexpensive method in the quantification of ar by the left ventricle to right ventricle stroke volume ratio (lv/rv sv ratio) has not been completely investigated. methods: between june 2005 and december 2007, 132 consecutive patient...
متن کاملDoppler echocardiographic index of global right ventricular function.
Ventricular Function To the Editor: In pulmonary disease, right ventricular dysfunction has an important bearing on prognosis.1 Incalzi et al2 recently demonstrated the prognostic implications of electrocardiographic signs of chronic cor pulmonale in patients with chronic obstructive pulmonary disease. Two electrocardiographic features in particular, an S1S2S3 pattern and a P-wave axis of .90°,...
متن کاملRight Ventricular Non-Compaction Cardiomyopathy in Children: Brief Review Literature
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 ...
