A semi-quantitative programme for evaluating radio-ventriculograms by a "first passage" technique (author's transl)

Abstract

Evaluation depends mostly on the demonstration of regional function (muscle movement, regional contraction volume, trend scintigram). A special technique permits the demonstration of insufficiency of the A-V valves and its approximate measurement. Comparison with single plane angiography showed good or excellent agreement concerning the ejection fraction (r = 0.86 for patients in sinus rhythm, 0.92 for patients without valvular disease). Inter observer error is very small (r = 0.99). These studies can be evaluated separately for the right and left ventricles (in an RAO 30 degrees projection).
