Postoperative Weight-Gain in Early Infants with Symptomatic Large Ventricular Septal Defect

PURPOSE: To investigate the postoperative patterns of weight-gain in early infants with ventricular septal defects (VSDs), we analyze 48 patients who received primary surgical closure of the symptomatic VSDs during 6 months of age in the period of 1993 through 1995. METHODS: Forty-sixt infants met criteria for inclusion in the study. The mean follow up period was 14 months (3 to 36 months). Weight percentile was extrapolarated from data of the Korean boys and girls measured in 1985. The data was compared by one-group paired student t-test. RESULTS: The overall mortality rate of this study was 4% (2/48). No surviving patients required a second ventricular septal defect operation, and the majority no longer received anticongestive therapies. The mean percentile of the preoperative weight was 3.53. In postoperative follow up period, they grew steadily. But, the mean weight percentile was only 5.46 in age under 6 months. Mean 12 percentile was achieved in age of 6 to 8 months, hence 25.4 percentile in 9 to 12 months, 33.5 percentile over 12 months, 64.8 percentile over 24 months of age. The weighing pattern of the patients with smaller defect was similar in 24 patients (52%) with large VSD, which size were same or larger than diameter of the aortic root. CONCLUSIONS: This study indicated that the patients under 6 months who have undergone primary surgical closure of the symptomatic large ventricular septal defects could gain the weight normally in postoperative period. Although the weight-gain was not sufficient when the age was under 12 months, It became normal pattern of weighing in age over 12 months.

Early Postoperative Results of the Large Ventricular Septal Defect in Infants Younger Than 1 Year of Age

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.
