The developing of cuantitative angiographic procedures for evaluating the left ventricular efficiency have displaced most of the simple hemodynamic methods. The calculation of the left ventricular volume by usual ventriculography yields, as a rule, magnified values. The purpose of this paper is to determine the equation of the regression line means of which the real left ventricular volume can be calculated. A series of 12 normal hearts obtained from accidentaly deceased adult individuals (this necropsy material was afforded by the Forensic Medicine Department of México City). Previously measured amounts of a contrast substance were injected into the left ventricular cavity. The heart was filmed in a position equivalent to the chest RAO. The volume of the left ventricle was calculated using monoplane Sandler and Dodge cineventriculographic method. The results were submitted to statistic analysis. Confrontation of calculated and real values rendered a significative "r" (0.7374) and a non-significant "p" (0.001) the regression equation obteined was: y=36.97 + (0.39 x) in which: y=real left ventricular volume. x=calculated left ventricular volume.
