- Abstract: Objective To summarize the reoperation experience for complete atrioventricular septal defect (CAVSD) with severe left atrioventricular valve regurgitation (LAVVR) by standardized mitral repair-oriented strategy. Methods From 2016 to 2019, 11 CAVSD patients underwent reoperation for severe LAVVR by standardized mitral repair-oriented strategy at Fuwai Hospital, including 5 males and 6 females with a median age of 56 (22-152) months. The pathological characteristics of severe LAVVR, key points of repair technique and mid-term follow-up results were analyzed. Results The interval time between the initial surgery and this surgery was 48 (8-149) months. The aortic cross-clamp time was 54.6±21.5 min and the cardiopulmonary bypass time was 107.4±38.1 min, ventilator assistance time was 16.4±16.3 h. All patients recovered smoothly with no early or late death. The patients were followed up for 29.0±12.8 months, and the echocardiograph showed trivial to little mitral regurgitation in 5 patients, little regurgitation in 5 patients and moderate regurgitation in 1 patient. The classification (NYHA) of cardiac function was class Ⅰ in all patients. Conclusion Standardized mitral repair-oriented strategy is safe and effective in the treatment of severe LAVVR after CAVSD surgery, and the mid-term results are satisfied.
