이오네스큐 대동맥판막의 내구성 = Durability of the aortic Ionescu-Shiley xenograft valve

다국어 초록 (Multilingual Abstract)

endocarditis, 1.475% /pt-yr, overall valve failure, 3.319% /pt-yr; and primary tissue failure, 1.475% /pt-yr. The actuarial probability of survival was 94.3$\pm$3.6% and the probability of freedom from thromboembolism 90.6$\pm$4.6% at 11 years after surgery respectively. And, the probability of freedom from primary tissue failure was 60.4$\pm$16.9% also at 11 years The evidence of possible premature and accelerated failure of the pericardial valve in the aortic position among the young population was not clear on the age-related analysis of the structural failure, and no suggestion could be made to indicate age limit when the use of the pericardial valve would better be avoided.
