Abstract:
Objective To investigate the durability of the cryopreserved valved homograft conduit (VHC) used in reconstruction the right ventricular outflow tract (RVOT) and its risk factors. Methods 119 cases undergoing VHC reconstruction the RVOT in our hospital between November 1989 and July 2003. 65 cases were followed-up, including the clinical examination, electroeardiography, chest radiography, echooardiography, or cardiac MRI for detection of development of homograft calcifications, obstruction and conduit valve regurgitation, and we used the morden statistics method to analyze the factors for the VHCs' durability. Results Among 65 cases, the median survival time for the VHCs was 10.9 years. The longest survival lasted for 12.8 years.The homografts failure was 15.4% . Conclusion The younger age(≤4y), smaller weighl(≤10 kg),aortic homograft are the risk factors for the VHC' durability(P
