Surgical therapy analysis of common congenital heart disease in 1 004 infants

Objective To analyze the surgery effect of infant common congenital heart diseases. Methods The clinical data of 1 004 infants with common congenital heart disease were retrospectively analyzed, with male in 508 cases, female in 496 cases, age from 0.7 to 12.0 (7.4 ± 3.6) months, and body weight from 2.4 to 11.5 (6.8±2.2) kg. Among them , there were the ventricular septal defect (VSD) in 680 cases, atrioventricular septal defect (ASD) in 92 cases, patent ductus arteriosus (PDA) in 70 cases, pulmonary valve stenosis (PS) in 12 cases, VSD + ASD in 83 cases, VSD + PDA in 27 cases, VSD + moderate to severe mitral insufficiency (MI) in 12 cases, VSD + ASD + MI in 3 cases, VSD + PS in 5 cases, VSD + ASD + PS in 2 cases, VSD + double chamber right ventricle (DCRV) in 3 cases, and ASD + PS in 7 cases, ASD + PDA in 8 cases. Results The extracorporeal circulation time was 21-72 (40.2 ± 28.6) min, and aortic occlusion time was 4-37 (20.7±15.5) min. The in hospital mortality was 0.8% (8/1 004). Postoperative complications included low cardiac output syndrome in 18 cases, bacterial endocarditis in 2 cases, pneumonia in 27 cases, pulmonary atelectasis in 6 cases, pneumothorax in 2 cases, laryngeal edema in 11 cases, incision fat liquefaction in 12 cases, sternal dehiscence in 3 cases, and third-degree atrioventricular block in 1 case. Eight hundred and forty-five infants (84.2%, 845/1 004) were followed up for 6-12 months.The echocardiogram found 9 cases with residual VSD shunt, 5 cases with mild MI and 1 case with moderate. Conclusions In primary hospital, Seizing the opportunity of surgery, attention on protection of myocardium and other important of organ function during operation, and postoperative intensive care and fine processing can achieve satisfactory clinical results in infant common congenital heart diseases surgery.
