ABSTRACT
PURPOSE:
The aim of this study was to evaluate the long-term results of aortic valve replacement (AVR) with mechanical (M) and bioprosthetic (B) valves as recommended by the Japanese guidelines.METHODS:
From April 1995 to March 2014, 366 adult patients underwent AVR. Of these, 127 (35%) patients received M and 239 patients (65%) received B valves. A retrospective analysis of the entire and the selected 124 patients aged 60 to 70 years was carried out.RESULTS:
In patients aged 60 to 70 years, the 15-year survival and freedom from reoperation were 88% ± 7% and 100% for the M group and 34% ± 25% (p <0.001) and 73% ± 14% (p = 0.059) for the B group, respectively. Among propensity score matching of the subgroup, there was no significant difference in survival and freedom from reoperation. The rate of thromboembolism was higher in the M (M 0.58% vs B 0.35% patient per year, p <0.001) and the rate of hemorrhage was higher in the M group (M 0.34% vs B 0.12% patient per year, p <0.001).CONCLUSION:
The current strategy of aortic valve choice based on the Japanese guidelines has provided excellent long-term results so far.
