[Midterm Outcomes of Root Replacement Using Homograft for Aortic Valve Infective Endocarditis].

From August 2003 to June 2013, 9 patients with aortic valve endocarditis underwent aortic root replacement using homografts which were harvested and preserved in our institute. The median patient age was 62 years (range 46~84) and 5 patients were men. Four cases were prosthetic valve infections. The in-hospital mortality was 0%. In 8 of 9 cases were evaluated on midterm outcomes. At a median of 52 months (range 19~156), overall survival was 100%, freedom from cardiovascular events was 87.5%. The peak aortic pressure gradient was 9.04 ± 4.2 mmHg. Aortic regurgitation was less than 2 of 4 in all cases.
