[Differences in postoperative course by preoperative left ventricular volume after closure of ventricular septal defect during early infancy].
A total of 38 early infants with ventricular septal defect (VSD) were divided into 2 groups by preoperative LVEDV. The group A (n=14, LVEDV>250% N) showed significantly longer period of intubation, cathecholamine drip, and hospitalization compared with the group B (n=28, LVEDV<250% N). At dischage, both groups showed significant lowered right ventricular (RV) pressure, but LVSF in the group A was significantly lower than that in the group B. The patients with larger left ventricular (LV) volume preoperatively were thought to be potential high-risk groups in cardiac and pulmonary function and their postoperative course was prolonged and recovery of LV function was worse. In such patients, special care is mandatory to do postoperative management and to decide timing of operation.
