Biplane roentgen angiography of the left ventricle can provide estimates of total ventricular function such as ejection fraction, stroke volume and myocardial mass correct to within 15% under the angiographically ideal conditions present in this preparation. It is unlikely, however, that more than average estimates of myocardial function can be obtained using biplane projection images. Use of estimates obtained from any one region of the ventricular silhouette may not in fact be representative of any other region of the ventricle and may differ by as much as 100%.
