Abstract

Ninety-nine cases of ventricular septal defect with septal aneurysm which were confirmed by angiocardiography and 2-D echocardiography during the period of 2 years from 1983 to 1984 at SNUH were studied and analyzed. The summary of the findings are as follows: 1) Septal aneurysm was found in 99(26.9%) of 368 cases of total VSD and in 38.2% among membranous VSD. 2) The youngest age when septal aneurysm was detected was 12 months. There is no increase in frequency by increasing age. Male to female sex ratio was T. 2 : 1 but its difference was not significant statistically. 3) In almost 90% of the patients with septal aneurysm, EKG and chest X-ray findings were normal or nearly normal. 4) Qp/Qs in cases with septal aneurysm was significantly smaller than those cases without septal aneurysm(P<0.01) and in 92.9% of the cases Qp/Qs was below 2.0. Right ventricular pressure was also within normal limits in most of the cases. 5) There was no significant difference in detection rate between angiocardiography and 2-D echocardiography. In conclusion, septal aneurysm was accompained with small VSD and the formation of aneurysm of the membranous septum appears to be one of the mechanisms of spontaneous closure of VSD beyond infnacy.
