[Surgical treatment of the double outlet right ventricle with pulmonary stenosis. Apropos of 7 cases]

Abstract

The double outlet right ventricle is a rare malformation, and its surgical correction has been well defined. The authors present seven cases of double outflow of the right ventricle and stenosis of the pulmonary outflow. If the technical problems of those variants with a subaortic septal defect seem to have been overcome, those with a subpulmonary ventricular septal defect present a much more difficult problem. Of the seven cases presented, the authors report the death of one patient who had a right ventricle with a double outlet associated with pulmonary stenosis and a sub-pulmonary ventricular septal defect. The post-operative course of the other 6 patients, who had a subaortic ventricular septal defect, was simple. One patient suffered secondary dehiscence of the repaired septal defect, and was reoperated on. The maximum follow-up period has been 7 years.
