[Quantification of ventricular volume. Comparative study of 2 angiographic methods].

The left ventricular volumes and the ejection fraction were measured in 78 patients who had different cardiopathies, in more than 50% the diagnosis of ischaemic heart disease of coronary origin was made. Every cineangiocardiogram was carefully observed to find those who had normal and abnormal ventricular contraction. The ventricular volumes were calculated by the Green method and afterwards the results were compared with the values obtained by the Sandler and Dodge method. A very good correlation was found between the two methods and we got the conclusion that although it is preferable to calculate ventricular volumes and the ejection fraction with biplane method or with Saudler and Dodge's monoplane, the results of the present work permit the use of Green's method in calculating ventricular volumes and obtaining confident results, independently of the ventricular contraction type with the exception of those who have large ventricular aneurisms.
