Reimplantation for annular stabilization in bicuspid aortic valve repair.

Abstract

To review the outcomes of bicuspid aortic valve repair with the reimplantation technique. From 2006 to 2018, 46 patients with bicuspid aortic valve underwent the reimplantation procedure for aortic valve repair. Those patients were included in this study. The mean age was 45 ± 15years and 44 were male. Preoperative echocardiography showed a mean ventriculoaortic junction diameter of 28 ± 3mm. The mean diameter at the sinus of Valsalva was 41 ± 9mm. The minimum cusp height was 19 ± 3mm. Regarding cusp repair technique, central plication was used in 45 patients, free margin reinforcement in 10 patients, and patch repair in 4 patients. Follow-up was performed by annual echocardiography. There were no hospital deaths. All patients were found with either no/trivial or mild AR on postoperative transesophageal echocardiography. The postoperative ventriculoaortic junction diameter was 23 ± 2mm and 83 ± 17% preoperatively. Freedom from moderate AR was 85 ± 6% at 5years, and freedom from reoperation was 93 ± 4% at 5years. Reimplantation for bicuspid aortic valve repair showed acceptable mid-term outcomes.
