Abstract

During the period of 18 months from December 1984 to May 1986, 41 cases(25.0%) of subpulmonic ventricular septal defect(VSD) were diagnosed among 164 cases of isolated VSD in the cardiac catheterization labortory. The incidence of aortic regurgitation associated subpulmonic VSD(19.5%) was much higher than that of the other types of VSD(2.4%). None of patients less than 1 year old developed aortic regurgitation, the incidence of which has increased with the age after that. That amount of left to right shunt through the VSD was smaller in the patients with aortic cusp prolapse than those without aortic cusp prolapse, and the severity of aortic regurgitation was correlated with that of aortic cusp prolapse. 10 out of 41 patients revealed more than 20mmHg pressure gradient through right ventricle outflow tract and 9 of these patient were as sociated with aortic cusp prolapse.
