Comparison of single and biplane ventriculography for determination of left ventricular volume and ejection fraction.

This study was done to compare single and biplane left ventriculography in quantitating left ventricular (LV) volumes and ejection fraction. LV volumes and ejection fraction were measured from a 30 degrees right anterior oblique single plane ventriculogram and a 30 degrees right anterior oblique 60 degrees left anterior oblique biplane ventriculogram in 152 men (aged 59 +/- 9 [mean +/- standard deviation] years), of whom 102 had hypokinesia, akinesia, or dyskinesia. There was excellent agreement between the results of single and biplane ventriculography with respect to LV end-diastolic volume (r = 0.
