[Angiocardiographic study after complete correction of interventricular communications treated by banding of the pulmonary artery. 20 cases (author's transl)]. / Etude angiocardiographique après correction complète des communications interventriculaires traitées par cerclage de l'artère pulmonaire. A propose de 20 observations

An angiographic study after complete correction in twenty children who had previously undergone banding of the pulmonary artery revealed a certain number of complications. The considerable percentage of residual V.S.D, the persistance of notable narrowing in the region of the zone of banding, and infundibular hypertrophy are mainly due to surgical difficulties. Two cases of pulmonary valve incompetence were detected with the appearance of thickened valves, which were isolated or associated with a "domeshaped" valve appearance. Kowledge of these complications enables reduction as far as possible of the indications for banding of the pulmonary artery.
