BACKGROUND: Unicuspid aortic valve is a rare anatomic variant, but patients may require intervention for severe valve dysfunction at a young age. We introduce a new reconstructive technique for diseased unicuspid valve by tricuspidization with glutaraldehyde-treated autologous pericardium.
METHODS: From April 2007 through January 2011, we performed 304 cases of aortic valve reconstruction using glutaraldehyde-treated autologous pericardium. During the same period, we encountered 9 patients with unicuspid aortic valve, including 8 male patients and 1 female patient. Mean age was 48.9±19.9 years (14-78 years). Two patients had aortic stenosis (AS), 1 had aortic regurgitation (AR), and 6 patients had both. Our original aortic valve reconstruction technique is characterized by the independent replacement of 3 leaflets with separate measurement of length between each commissure. In the case of a unicuspid aortic valve, we create a new commissure at a higher point along the raphe at the same level with the 1 normally existing commissure.
RESULTS: No early mortality or major morbidity was recorded. Postoperative echocardiography showed trivial or no AR, with the peak pressure gradients averaging 10.6±3.3 mm Hg. One-year follow-up echocardiography revealed that the peak pressure gradients averaged 8.6±3.7 mm Hg, with trivial or no AR. The mean follow-up period was 551.1±51.4 days. All 9 patients are in good condition. No reoperation or any additional intervention has been necessary.
CONCLUSIONS: Diseased unicuspid aortic valves were treated by our original aortic valve reconstruction technique with excellent early results. We continue to study the long-term results.
