[Ventricular septal defect: Prognosis of spontaneous closure (author's transl)]

In a series of 150 cases of isolated ventricular septal defect (VSD), the authors have found 25 cases (16%) of spontaneous closure over an average period of observation of 20 months. The closure was observed in 32% of the cases before 6 months and in 60% before 12 months, with a range between 1 month and 8 years. The number of out patient with was 7 per case on average. A large group of parameters was taken into account in every case; from some of them, indicators of prognosis of closure were obtained, among them: early appearance of the murmur, descending shape, muscular character of the VSD, absence of symptoms and diastolic rumble, presence of ejection clic and normality in ECG and XRay.
