Background. A new durable technique for aortic valve repair was developed for the treatment of aortic regurgitation. The aim of this study was to assess the efficacy and surgical results of this method.
Methods. From December 1997 to March 2004, 97 patients (34 women and 62 men with a mean age of 54 ± 16 years) with various causes of aortic regurgitation were treated by a novel technique of aortic valve repair. Isolated aortic regurgitation was seen in 26 patients, aortic dissection in 42, annuloaortic ectasia (AAE) in 16, and ascending aortic aneurysm in 12 patients. Mean follow-up was 9.3 ± 9.3 months.
Results. There were 3 deaths (3%), all occurring in aortic dissection. Early postoperative echocardiography showed no or trivial aortic regurgitation in 83 patients (86%), various degrees of improvement in 93 (97%), and no improvement in 3 patients (1 rheumatic aortic regurgitation, and 2 aortic dissection). Later follow-up echocardiography of 35 patients at a mean time of 8.0 months, showed absence of progression in aortic regurgitation in 31 patients (89%). The mean grade of aortic regurgitation was significantly decreased in the entire series from 2.6 ± 1.4 to 0.9 ± 0.9 ( p<0.05). The actuarial 5 year survival rate was 95.8 % and the actuarial rate of freedom from aortic re-operation was 97.9 %.
Conclusions. This new technique has clearly been shown to be safe and effective through this study. Although long-term results are unavailable, the findings nevertheless suggest the broad employment of this novel technique in the repair of aortic regurgitation to be feasible.
