[Results of 2-stage correction of ventricular septal defect with severe pulmonary hypertension]

From 1963 to 1985, 232 operations were carried out for constriction of the pulmonary artery in ventricular septal defect (VSD) with high pulmonary hypertension with 6% mortality. 74 patients were examined after a palliative operation. According to the results of catheterization of the heart cavities, the effect of the first stage of surgical correction of the defect was good in 55, satisfactory in 8, and poor in 11 patients. Radical operation for closure of VSD and debanding of the pulmonary artery were performed in 52 patients with 19.2% hospital mortality. During follow-up of the late-term results of two-stage correction of the defect catheterization of the heart cavities with angiocardiography was conducted in 13 patients, pressure in the pulmonary artery in 12 of them was normal (26.4 +/- 1.8%). Prevention of hemorrhage during freeing of the heart from adhesions as well as sparing techniques of VSD closure may reduce mortality in repeated surgical intervention essentially.
