Abstract

We reviewed a policy of primary surgical closure of large ventricular septal defects in small infants. Sixty-three infants met criteria for inclusion in the study, and were divided into two groups based on age: group 1 infants aged less than 5 months(n = 31), and group 2 infants aged 5 months or more(n = 32). Both groups had similar variation in ventricular septal defect location(paramembranous versus muscular), and showed no significant difference in left to right shunt and in ratio of systemic and pulmonary vascualr resistance. Three early deaths(9.7%) occurred in group 1, but no death(0%) in group 2. The causes of death were preoperative cardiac arrest and cerebral injury followed by postoperative respiratory insufficiency in two patients, and preoperative tracheomalacia followed by laryngeal edema and respiratory arrest in one. Two patients in group 1 showed postoperative low cardiac output syndrome(6.5% in group 1 versus 0% in group 2). There was no late death during the follow-up period in both groups. No surviving patients had postoperative patch leakage, or required a second operation. These results indicate that primary surgical closure of large ventricular septal defects, if logical perioperative care is accompanied, can be safely performed in small infants aged less than 5 months with low postoperative mortality or morbidity rates.
