Repair of complete atrioventricular septal defect between 2 and 3.5 kilograms: Defining the limits of safe repair

Middle to long-term outcomes of surgical repair for atrioventricular septal defect: a single-center study

“…Fong et al found decreased postoperative mortality over time and a better late survival in patients ≤3 months of age (12). Even for the complex CAVSD repair, complete repair performed on patients ≤3 months of age and weighing ≤3.5 kg was successful, with a 20-year survival rate of 92.0% and 83.8%, respectively, as reported by Buratto et al and Goutallier et al (3,13). On the basis of valvular morphology, individualized surgical strategies can be designed to improve the outcomes of AVSD patients.…”

“…The study was conducted in accordance with the Declaration of Helsinki (as revised in 2013). This retrospective study was approved by the Ethics Review Board of the Children's Hospital of Fudan University [No. (2022)132].…”

“…CPB temperature was controlled at an average of 32.44±1.92 ℃. After surgery, the median mechanical ventilation time was 27.5 (61.63) hours and the median of LOS in the intensive care unit (ICU) was 3.5 [2][3][4][5][6][7] [19-47.25] and 11.0 [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] hours; P<0.001}, and postoperative LOS in the ICU {6 [5][6][7][8][9][10][11] vs. 3 [2][3][4] and 2 [1-3] days; P<0.001} were significantly longer in the C-group compared to both the T-group and P-group. Furthermore, the incidence of complications was 28.4% (19/67) in the C-group, which was significantly higher than 7.7% (2/26) in the T-group and 8.8% (5/57) in the P-group (P=0.005).…”

“…In 1966, Rastelli classified three types of AVSD based on anatomical structure: complete (CAVSD), transitional (TAVSD), and partial (PAVSD) ( 1 ). Developed surgical techniques and peri-operative management have reduced AVSD-related mortality in children to about 10% over the past few decades ( 2 , 3 ).…”

A stitch in time: age impacts survival in repair of atrioventricular septal defects

“…In the majority of these patients there is significant LAVV regurgitation contributing to heart failure, and in these patients achieving a balanced circulation without exacerbating LAVV regurgitation is challenging. Furthermore, we have not observed an increase in the rate of LAVV reoperation with early repair, even in those under 3.5 kg (12). Our proposed algorithm for choosing between complete repair and pulmonary artery banding is demonstrated in Figure 1.…”
