Ventricular performance after angiocardiography.

Assessment of cardiac performance with quantitative radionuclide angiocardiography: sequential left ventricular ejection fraction, normalized left ventricular ejection rate, and regional wall motion.

Imaging Guidelines for Nuclear Cardiology Procedures: Equilibrium Radionuclide Angiocardiography (ERNA)

Planar equilibrium radionuclide angiocardiography (ERNA) is used to determine global and regional measures of ventricular function (primarily left ventricular [LV] function) at rest and/or during exercise stress or pharmacologic intervention. These measures of ventricular function may include evaluations of ventricular wall motion, ejection fraction (EF), and other parameters of systolic and di...

Left Ventricular Diastolic Performance

We used first-pass radionuclide angiocardiography to assess filling fraction during the first third of diastole, peak filling rate and peak filling rate during the first third of diastole as indexes of left ventricular diastolic performance at rest and after upright bicycle exercise in 32 normal patients and 68 patients with coronary artery disease. The mean filling fraction was unchanged from ...

Right and left ventricular performance in ambulatory young adults with cystic fibrosis.

Although cystic fibrosis is noted primarily for pronounced abnormalities in pulmonary function, a substantial number of patients die as a result of cardiac complications. Nevertheless, little is known about cardiac performance in this disease. The cardiac pathophysiological consequences of cystic fibrosis were investigated non-invasively by measuring right and left ventricular performance using...

Left 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...
