PURPOSE: There is not enough data about the aortic valve sparing and restoration with autologous pericardial leaflet extension among the acquired heart disease patients population. The purpose of this study is to evaluate the efficacy of this technique.
METHODS: Forty-three patients (n=43)with acquired valve disease underwent aortic valve repair with autologous pericardial leaflet extension from January 1997 through February 2006. The mean age was 56.7±19.78 (range, 7.8 to 84.6 years). 7% were less than 18 years old at the time of operation. The diagnosis included Aortic Regurgitation, mild (27 patients), moderate (1 patient) and severe (6 patients). Aortic Stenosis, mild (4 patients), Regurgitation and stenosis (5 patients), rheumatic fever (3 patients) and endocarditis (2 patients).
RESULTS: 30 days mortality (early deaths) was 0/43 and 3/43 (6.9%) late deaths at mean follow up of 33.11±28 (range, 0 to 93.1 months). 1/43 patients (2.3%) required reoperation (replacement). The interval between first and the second operation was 7.1 months. The remaining patients are well with a mean aortic regurgitation grade by echocardiogram of 0.7±0.66 (scale, 0 to 4) and aortic stenosis of 0.3±0.1 (scale, 0 to 4).
CONCLUSION: Aortic valve repair with pericardial leaflet extension is a reproducible and safe procedure providing a competent aortic valve in the acquired disease population. Prospective studies between aortic valve repair versus replacement are required in order to define more clearly the efficiency and the late outcome.
CLINICAL IMPLICATIONS: Aortic valve repair with pericardial leaflet extension is a reproducible and effective alternative in acquired valve disease, providing a competent aortic valve.
