    Summary
    In 42 consecutive patients undergoing biplane left ventricular cine-angiography, left ventricular volumes were first determined ultrasonically using a phased array transducer. To this end, two orthogonal apical long axis views were recorded one illustrating all four chambers, the other being the ‘RA O equivalent' view. Left ventricular volumes wer estimated by applying the area-length method to both two-dimensional echocardiograms and cine-angiograms, consistently including in the former the left ventricular outflow tract of the ‘RAO equivalent' view. The echocardiographic approach employed was shown to yield good predictions of the angiographic results. For the end-diastolic volume the correlation is characterized by r=0.98 and SEE 21 ml or 9.7% of the angiographic mean and for the end-systolic volume by r=0.97 and SEE 17 ml or 18.1% of the mean. The correlation for the ejection fraction showed an r value of 0.87 and a SEE of 5.4%. Equally good correlations were obtained in the subgroup with wall motion disorders for which the r values of the end-diastolic and end-systolic volumes were both 0.98 and that of the ejection fraction was 0.89
