Between 1975 and 1981, 171 patients(pts) had ventricular septal defect, as isolated one or one part of various multiple congenital malformations, at catheterization. Ninety of these pts(52.5%) had isolated VSD, and 45(26%) had tetralogy of Fallot. Other associated anomalies include ASD, PDA, AI, MI, TGA, DOLV, COA, PS, sinus valsalva rupture, tricuspid atresia, pulm. atresia, single atrium and bilat. SVC. Fifty-two VSD patients were operated upon with conventional extracorporeal circulation. In these operated cases, Kirklin's type II VSD were most common(24/52, 46%); followed by type I(12/52), type III(11/52), type IV(1/52), multiple VSD(2/52) and LV-RA shunt(1/52). The hospital mortality was 7.7%(4/52). Transient complete heart block occurred in 3 pts. Of the survivors, 44% had RBBB(21/48) and 7 of them had associated left anterior hemiblock(LAH). In all 7 pts with immediate post-operative LAH, left axis deviation become normalized within 5 months after operation(post-op. 1 day-5Mo.). We also analized pre-operative ECG, chest PA and hemodynamic data of VSD, which showed us the close correlation between ventricular hypertrophy patterns in ECG and hemo dynamic datas(LVH with Qp/Qs, and RVH with peak systolic pressure of pulmonary artery or Pp/Ps), and then correlation with post-operative results.
