Ventricular performance after angiocardiography.
Ventricular performance was assessed before and after angiocardiography in 22 patients with normal left ventricle, mitral stenosis, aortic stenosis, and myocardial disease. The increased circulating blood volume known to occur after angiocardiography is a determinant of the increased ventricular pre-load. The after-load is unchanged. Patients with normal left ventricle and some patients with va...
متن کاملLeft ventricular performance after myocardial infarction assessed by radioisotope angiocardiography.
Radioisotope angiocardiography was performed by peripheral venous or pulmonary arterial injection of 99mTc pertechnetate in 64 patients with acute myocardial infarction. End-diastolic volume determined with this technic averaged 101 + 7 (+ SEM) ml/m2 and was elevated (>90 ml/m2) in 47 patients. Initial ejection fraction (EF) averaged 0.38 + 0.03 and was reduced (<0.52) in 58 patients. The exten...
متن کاملLeft Ventricular Performance Assessed by Radionuclide Angiocardiography and Echocardiography
In 61 patients (77 studies) who had a transmural myocardial infarction, we compared the left ventricular ejection fraction by echocardiography with the ejection fraction determined by a computerized radioisotope technique that makes no assumptions regarding left ventricular geometry. In 31 studies of 26 patients with normal left ventricular wall motion by videotracking and normal left heart siz...
متن کاملLeft ventricular angiocardiography in atrioventricular defects.
The variation in the pathological anatomy of atrioventricular defects influences presentation, prognosis, and the results of surgical treatment. In particular the structure and function of the mitral valve have an important bearing on the success of surgical correction of the deformed valve. The purpose of this paper is to indicate the value of left ventricular angiocardiography in assessing th...
متن کاملLeft ventricular performance assessed by radionuclide angiocardiography and echocardiography in patients with previous myocardial infarction.
In 61 patients (77 studies) who had a transmural myocardial infarction, we compared the left ventricular ejection fraction by echocardiography with the ejection fraction determined by a computerized radioisotope technique that makes no assumptions regarding left ventricular geometry. In 31 studies of 26 patients with normal left ventricular wall motion by videotracking and normal left heart siz...
