[The efficacy of the angiographical method in the evaluation of left ventricular muscle mass in the dog (author's transl)].

In nine closed chest mongrel dogs 42 left ventricular cineangiographies for determination of left ventricular muscle mass were carried out. Buetterich's method was verified and a different procedure of calculation of myocardial wall thickens was proposed. By this method a better correlation line between calculated and weighed left muscle mass and a lower standard error of estimate is obtained.
