Abstract: Objective To investigate the prognosis of residual shunt after surgical repair in infants. Methods We selected 407consecutive infant patients (255 males and 152 females) with venticular septal defects(VSD) between January 2008 and June 2008 in Shanghai Children’s Medical Center, Shanghai Jiaotong University. Of the patients, 273 were less than 1 year
old, 88 were 12 yearsold, and 46 were 23 years old. All of whom underwent surgical repair of the ventricular septal defect with autologous pericardial defect treated by glutarald
ehyde. Results Of the 407 patients, 29 had residual ventricular septal defects, there was no significant difference among age groups in the rate of residual shunts （χ2=0.054，P=0.973）.Twentynine patients were followedup,and in the followup period of 1.5 months to 2 years postsurgery, 26 patients had spontaneous closure, while the other 3 patients did not heal. None of the patients needed reoperation. There was no significant difference among
age groups or type of ventricular septal defect in the rate of residual shunts (χ2=1.035，P=0.596). Conclusions Postsurgical residual ventricular septal defects smaller than 0.4 cm will close spontaneously in most infants.
