[Corrective surgery of double-outlet right ventricle and subaortic ventricular defect. Report of 12 cases surgically treated (author's transl)].

Experience with corrective surgery in 23 pts with double outlet right ventricle (DORV) and subaortic VSD is presented. The overall hospital mortality was 17%. Patients were divided into two groups: Group I includes seven cases without pulmonic stenosis and Group II sixteen cases with pulmonic stenosis. Six of Group II required a sistemic to pulmonary artery shunt earlier in life. Anatomic and clinical aspects in both groups are described as well as indication for surgery. The importance of angiocardiography for a precise diagnosis is emphasized. Problems related to management and complications are discussed; in particular how to avoid LVOTO in case of restrictive VSD and RVOTO in patients with pulmonic stenosis.
