Retrospective analysis of 1 96 cases of children under 12 months of age with ventricular septal defect underwent radical surgery. Confirmed by color echocardiography membrane peritoneal laxity in 1 64 cases, 31 cases of intracranial crest and dry room, myenteric ventricular septal defect in 3 cases. The average defect diameter was 9.4 ± 2.2 mm, suggesting that 103 patients had moderate-severe pulmonary hypertension. 9 cases of right heart catheterization, systolic blood pressure 5. 8 ~ 11.6kPa, diastolic blood pressure 2.1 ~ 6.7k Pa. One hundred and fifty-seven cases with moderate hypothermia were treated with deep hypothermia and low-flow cardiopulmonary bypass in one stage. Three patients died in the whole group, with a mortality rate of 1.53%, including 2 cases of low cardiac output syndrome, Infection in 1 case. Tip: Infant ventricular septal defect accurate grasp of surgical indications and timing of surgery
