Abstract:
Objective:To discuss the surgical treatment and early-mid follow-up results of complete atrioventricular septal defect (CAVSD).
Methods:The clinic data of 235 cases of CAVSD underwent surgical treatment at Department of Cardiac Surgery, Guangdong General Hospital from June 2009 to June 2016 was analyzed retrospectively (104 male and 131 female patients). The patients were aged 18 days to 58 years (mid age 8.9 months) at surgery, and 2 cases of newborns (0.9%), 24 cases of 1 to 3 months (10.2%), 56 cases of 4 to 6 months (23.8%), 66 cases of 7 to 12 months (28.1%), 36 cases of 1 to 3 years (15.3%), 37 cases of 4 to 18 years (15.7%), and 14 cases above 18 years (6.0%). There were 129 cases of Rastelli type A (54.89%), 16 cases of type B (6.8%), 25 cases of type C (10.6%) and 65 cases of transitional type (27.7%). The patients were combined with 7 cases of unroofed coronary sinus syndrome, 5 cases of coarctation of aorta, 4 cases of tetralogy of Fallot, 3 cases of double outlet right ventricle, 1 case of transposition of the great arteries, 1 case of multiple ventricular septal defect, 1 case of pulmonary artery sling. The CAVSD correction operations were performed in 199 cases with modified single patch technique (84.7%), 26 cases with two patch technique (11.1%), 10 cases with conventional single patch technique (4.3%), and the corrective surgeries of other anomalies were performed in the meantime. Generalized Estimated Equation was used to statistical analysis of postoperative regurgitation level of mitral valve and tricuspid valve.
Results:Followed-up for 1 to 7 years, 18 cases (7.7%) died overall and 15 cases (6.4%) died within 30 days post-operation.The mortality of little infant (operation age ≤3 months) was much highest(26.9%). The mortality of different operation age had significant difference(P=0.007). There was no difference among the mortality with three techniques. Seven cases (3.0%) suffered from the re-operation for severe mitral regurgitation. A total of 217 patients survived more than 1 year after initial surgery, and there were 11 cases (5.1%) with severe mitral regurgitation and 7 cases (3.2%) with severe tricuspid valve regurgitation at 1 year post-operation.The degree of mitral regurgitation after operation decreased at 1 week to 6 months, and slightly higher after 1 year postoperatively.The ratios of severe mitral regurgitation in different operative age group was statistically significant difference(P=0.017), mainly from 3 months group and 1 to 3 years group.The degree of tricuspid regurgitation decreased significantly after operation, and decreased gradually in the follow-up period. The ratio of postoperative residual severe tricuspid regurgitation was the highest in surgical aged >18 years old, less in 3 years group, the lowest in 3 to 18 years group.
Conclusions:The mortality and the ratio of patients with serious mitral regurgitation were higher in infants less 3 months than elder patients. The infants need more frequently follow-up and medicine treatment after operation. The modified one patch technique is effective for all age groups.
