BACKGROUND AND AIM OF THE STUDY: The aortic valve-sparing reimplantation operation (David) is increasingly used in @entity1 with @entity449 and intact cusps. David's procedure is also feasible in @entity1 with @entity4503 ( @entity4503 ), though few long-term data are available. METHODS: An analysis was conducted of the long-term echocardiographic data from @entity1 with @entity62158 who had undergone David's procedure at early and long-term follow up (FU) examinations. RESULTS: Between 1994 and 2010, a total of 30 @entity1 with @entity62158 underwent David's procedure at the authors'institution. There were no in-hospital or late deaths, and the mean long-term FU was 6.64    3.54 years (range: 3.2-20.1 years). The mean @entity337 ( @entity337 ) grade was increased from 0.26    0.37 at early FU to 0.70    0.80 at long-term FU (p = 0.013). Four @entity1 (13%) had to be reoperated after 10.00    4.74 years (range: 5.49-17.06 years) due to @entity472 (n = 1) and @entity337 (n = 3); the latter three @entity1 had a significant prolapse of both the fused and the non-coronary cusp of reconstruction. CONCLUSION: The mean @entity337 grade was increased significantly but was  <= I-II in 59% of @entity1 and  <= II in 93% of @entity1 after a mean FU of 6.6 years. @entity1 with prolapsing non-coronary leaflet at reconstruction seemed vulnerable to recurrent @entity337 . Among @entity1 , survival was excellent, and the reoperation rate and hemodynamics acceptable. Long-term follow up data are necessary to further refine the surgical techniques employed and to improve the results achieved.
