| Abstract |
|
We studied, with echocardiography as a main tool, the natural processes of 211 patients with uncomplicated ventricular septal defect(VSD)(incidence, 5.33 per 1,000 live births); 146(69.2%) had a perimembranous VSD and 32 (15.2%) had a subarterial, 25(11.8%) had a muscular type of VSD. Cumulative rate of spontaneous closure was 26.1%. In the closure processes, about three-fourth of perimembranous VSd showed a partial closure or tunnel formation by changes of septal leaflet of the tricuspid valve, remaining one-fourth showed a "functional" complete closure. Four of 58 nenonates had a partially closed-perimembranous VSD. Rates of infundibular stenosis and Eisenmenger sysndrome were 6.6% and 1.4% respectively. Aortic prolapse with insufficiency was detected in 6 patients who were over 6 years of age. Surgical closure was required in 27.5% of all studied patients and in 12% of infants(14 of 117). No natural deaths were observed during the study-periods of recent 3 years. But, 3 of 58(5.2%) were dead postoperatively (two were early, one late). Doppler color flow mapping is a valuable aid in the diagnosis of VSD and may be one reason for the observed increase in the incidence of VSDs. |
