Abstract

During the period of 9.5 years from September, 1985 to March, 1995, 32 cases with spontaneous closure in simple ventricular septal defect(VSD) were observed and evaluated at Yeungnam University Hospital, and those were confirmed by 2D-echocardiogram. The results were as follows: 1. Among these 32 cases, there were 23 cases(71.9%) of perimembranous VSD, 8 cases(25.0%) of muscular VSD and 1 case(3.1%) of subarterial VSD. Septal aneurysms appears to be main mechanism of spontaneous closure of VSD because of the presence of septal aneurysm in all cases with spontaneous closure of a perimembranous VSD. 2. The size of the defect was variable in diameter, but 27 cases(81.2%) were less than 5 mm. 3. The mean age was 12.1 months at spontaneous closure with the range from 1 month old to 72 months. 4. The mean weight was 9.0 kg at spontaneous closure. 5. Among these 32 cases, 3 cases had the clinical evidence of cardimegaly or congestive hert failure during infancy. 6. Male to female sex ratio was 1.5:1.
