Normal myocardial function in severe right ventricular volume overload hypertrophy.
Severe left ventricular volume overloading causes myocardial and cellular contractile dysfunction. Whether this is also true for severe right ventricular volume overloading was unknown. We therefore created severe tricuspid regurgitation percutaneously in seven dogs and then observed them for 3.5-4.0 yr. All five surviving operated dogs had severe tricuspid regurgitation and right heart failure...
متن کاملVectorcardiographic differentiation between right ventricular hypertrophy and posterobasal myocardial infarction.
Vectorcardiograms were recorded by the Frank lead system in 203 cases of right ventricular hypertrophy (RVH) and 85 cases of posterobasal myocardial infarction (PBMI). Of the RVH cases, 33 were confirmed by autopsy and 135 by cardiac catheterization or surgery. Of the cases of PBMI, 12 were confirmed by autopsy and 48 had definite clinical episodes associated with enzymatic or serial electrocar...
متن کاملRight ventricular hypertrophy.
The electrocardiograms of 22 cases showing isolated right ventricular hypertrophy at autopsy were examined for changes suggestive of right ventricular hypertrophy. Only 5 of 22 cases fulfilled at least one of the criteria of Sokolow and Lyon and only three could be diagnosed as having right ventricular hypertrophy by the criteria of Myers, Klein and Stofer. Factors contributing to the developme...
متن کاملPolycythemia and Right Ventricular Hypertrophy.
• The chronic hypoxia of high altitude produces an elevated pulmonary arterial pressure" resulting in right ventricular hypertrophy.' Cournand has proposed that the pulmonary hypertension and subsequent right ventricular hypertrophy found in patients with chronic pulmonary disease are associated with polycythemia, hypervolemia, and increased cardiac output secondary to the hypoxemia present in ...
متن کاملPrognostic 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 ...
