Abstract

PURPOSE: We report the results of a policy of primary surgical closure of large ventricular septal defects(VSDs) applied over the past 3 years to all symptomatic infants regardless of patient weight, location or number of VSDs. To analyze the early postoperative mortality and other surgical complications in young infants, comparison of preoperative and outcome variables were made between infants weighing 6 kg or less and those weighing mort than 6 kg at the time of operation.
METHODS
Forty-eight infants met criteria for inclusion in the study, and were divided into two groups based on body weight: group 1 infants weighed 6 kg or less(n=24), and group 2 infants weighed more then 6 kg(n=24). Both groups had similar variation in ventricular septal defect location and the ratio of the flow. resistance.
RESULTS
The major associated cardiac defects were more in group 1. The overall mortality rate of this study was 4%(2/48): Two early deaths occurred in only group 1(8%). Both infants had a doubly committed subarterial defect and mild degree of coarctation of aorta (one was a preductal type). One received a coatctation-repari. There was o only one patch dehiscence(in group 1). No surviving patients required a second ventricular septal defect opetation, and the majority no longer received anticongestive therapies.
CONCLUSIONS
These results indicate that primary surgical closure of large ventricular septal defects can be performed in small infants with no difference in mortality or serious complication rates compared with larger infants. Protracted medical efforts to achieve larger size before primary repair and palliative pulmonary artery banding are not necessary.
