Abstract
- From January to December 1984, 191 patients with associated ventricular septal defect(VSD) were studied in the cardiac cathetherization laboratory. Among theses 191 cases, 58 cases(30.4%) of subpulmonic VSD were identified by angiocardiography. Among the 59 cases of subpulmonic VSD, 12 cases(20.6%) were complicated with aortic infficiency(AI). The relative frequency of subpulmonic VSD increased with the increase of age and the frequency of complication of AI with the subpulmonic VSD also increased with the increase of age. The amount of left to right shunt in the patients with subpulmonic VSD and AI was small and Qp/Qs ratio was less than 2.0 in all of the 12 cases. Among the 12 patients 4 cases had a pressure gradient greater than 20 mmHg across the infundibular region of the right ventricle.
