[Interventricular communications with aortic insufficiency surgical considerations].

The authors report a series of 11 patients with ventricular septal defect associated with aortic incompetence who underwent surgery between 1963 and March 1976. Separate consideration is given to the operations performed before and after 1972. 5 patients were operated on during the first period, with only mediocre results. At this time, the technique of valvuloplasty did not appear to be the right one. During the second period, 6 patients were operated on. In five of them the technique of Plauth, Frater, Spencer and Trusler was used. All these patients have a satisfactory result. The last of the series had an abnormally low commissure, and the adjacent valves were protuberant, and thickened, so that a valvular replacement was carried out. The operation of choice for a ventricular septal defect associated with aortic incompetence is valvuloplasty with closure of the defect. The following criteria are necessary indications for this type of surgery: --the aortic incompetence must be secondary to the prolapse of a valve; --the aortic valve must have three cusps. An early operation makes the valvuloplasty easier, and avoids the problems of damage to the left ventricle from a persistant and progressive aortic incompetence.
