The authors compare 5 methods of evaluating left ventricular volume and the ejection fraction by monoplanar angiocardiography in the 30 degrees right oblique incidence: the method of Green (1 and 2), Snow and Dodge, and by trapezoidal integration which was used as a reference. The have calculated the regression ordinates and the correlation coefficients for various systolic and diastolic volumes as well as for various ejection fractions. For these latter, Dodge's quadratic equation can also be used. Provided there is no gross distorsion of ventricular contolr, there is fairly good correlation, but there is a marked discrepancy for large volumes or small ejection fractions (less than 0.40). When more elaborate methods are not available, it seems reasonable to use a single method to calculate these parameters, but it is essential to have recourse to other techniques when there are gross changes in the left ventricle.
