title: [Dynamic cardiomyoplasty. Hemodynamic study of 3 patients].
abstract: Dynamic cardiomyoplasty is a surgical operation aimed at compensating for a loss of substance or a severe deficiency of the left ventricular myocardium by implanting around the heart the latissimus dorsi muscle the contraction of which, synchronous with that of the ventricles, acts on the heart in the manner of a massage or milking. The operation, which in its present form is recent, consists of applying Onto the heart, or wrapping that organ with, a skeletal muscle that keeps its neurovascular supply and its high insertion, and of installing the appropriate electrodes and a pacemaker. We report the haemodynamic data collected in 3 patients operated upon for severe cardiac failure 13, 8 and 9 months ago respectively and who are now in NYHA functional stages I and II. During 1/1 stimulation of the latissimus dorsi systolic pressures remain unchanged while diastolic pressures rise; cardiac output increases satisfactorily in two of the patients (cases No. 1 and 3) and is unmodified in the third one (case No. 2). We conclude that cardiomyoplasty seems to give favourable results but its future and indications remain to be determined.
