Aim. Repair of the bicuspid aortic valve is not generally considered the treatment of choice. Our success with this procedure leads us to report our immediate and mid-term results.
Methods. From August 1993 to December 2000, 19 patients with aortic regurgitation due to congenital aortic valve underwent aortic valve repair (17 men and 2 women with a mean age of 42±17 years; range, 16 to 70 years). The mean preoperative aortic regurgitation grade was 3.1±0.8 on a scale of 1 to 4. Mean preoperative New York Heart Association functional class was 1.9±0.8. Fourteen patients had pure aortic regurgitation, 2 also had infectious endocarditis, 1 had angina pectoris, and 2 had an ascending aortic aneurysm.
Results. There was 1 hospital death (5.2%), and 1 patient required re-operation due to recurrent infectious endocarditis. Mean aortic regurgitation grade at discharge was 1.1±0.9, and functional class was 1.1±0.2. All patients were followed for a mean duration of 40±23 months (range, 0.5 to 84 months). There was 1 late death, and two patients required aortic valve replacement. The 5-year survival rate was 90±7%. The 1- and 5-year re-operation-free rates were 87±12% and 76±23%.
Conclusion. Bicuspid aortic valve repair is a safe procedure with good early postoperative results. However midterm results are not satisfactory. Re-operation is a promising alternative and progress aortic regurgitation were complications. Bicuspid aortic valve repair to valve replacement that requires additional study to individualize treatment.
