[Ventricular septal defect in the first year of life (author's transl)].

: Thirty cases of CIV in the first year of life are presented. Association with prematurity and other malformations anticipate cardiac failure. Left ventricular hypertrophy is more frequent in conal defects. Repolarization disturbances were found in 73% of the cases in left precordial derivation with significative relief after surgical repair (banding). Conduction disturbances after surgical closure of ventricular septal defect was found in 15% of the cases. Surgical treatment during the first year was needed in 86% of patients. Only one case had good evolution without surgery. After four months of life total correction of septal defect as prefered. In patients with previous pulmonary artery banding, correction must be made one or two years later.
