ABSTRACT
@#Objective To evaluate the short and mid-term outcomes of valve repair in patients with insufficient bicuspid aortic valves (BAV). Methods The clinical data of 27 consecutive patients with insufficient BAV undergoing valve repair in Shanghai Chest Hospital from September 2016 to January 2020 were retrospectively reviewed. There were 24 males and 3 females with a mean age of 38.5±14.6 years (range: 20-68 years). BAV of all patients was type 1 in Seviers' classification. There were 23 patients with left-right fusion and 4 patients with right-noncoronary fusion. There was aortic regurgitation in the patients measured by the echocardiogram, including moderate regurgitation in 3 patients, moderate-severe in 18 patients, and severe in 6 patients. The diameter of aortic annular base was 27.9±3.4 mm, and the largest diameter of aortic sinus was 39.9±7.6 mm. Left ventricular end diastolic diameter was 62.7±6.5 mm, and the volume was 197.9±53.6 mL. Results All 27 patients completed the follow-up, and the mean time was 24.2±12.5 months (range: 12-51 months). No patient died or required aortic valve-related reoperation during the follow-up. The cardiac function of the patients significantly improved postoperatively (P<0.05). By echocardiography, 11 patients had no aortic regurgitation, 13 had mild aortic regurgitation, and 3 had moderate aortic regurgitation, and no patient had severe aortic regurgitation. Postoperative left ventricular end diastolic diameter and volume decreased, compared to preoperative ones (P<0.05). Conclusion In patients with insufficient BAV, valve repair is safe and effective, and has excellent short and mid-term outcomes.
