Objectives:
To review the outcomes of bicuspid aortic valve repair with the reimplantation technique.
Patients And Methods:
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 ± 15 years and 44 were male. Preoperative echocardiography showed a mean ventriculoaortic junction diameter of 28 ± 3 mm. The mean diameter at the sinus of Valsalva was 41 ± 9 mm. The minimum cusp height was 19 ± 3 mm. 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.
Results:
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 ± 2 mm and 83 ± 17% preoperatively. Freedom from moderate AR was 85 ± 6% at 5 years, and freedom from reoperation was 93 ± 4% at 5 years.
Conclusions:
Reimplantation for bicuspid aortic valve repair showed acceptable mid-term outcomes.
