Aortic homografts have been used in young patients requiring aortic valve replacement(AVR). Currently, they are generally reserved for aortic valve endocarditis with or without root abscess, however, longitudinal data are lacking. Our aim was to assess the long-term safety and durability of homograft implantation. All adult patients undergoing aortic homograft implantation at a single institution from 1992-2019 were included. Outcomes of interest included all-cause mortality and AV reoperation, studied over a median follow-up duration of 19 years. A total of 252 patients were included, with a mean age of 49 years. Infective endocarditis was the primary indication for surgery in 95(38%) patients. The endocarditis group had a higher prevalence of NYHA III-IV(56% vs. 26%), chronic kidney disease(CKD)(22% vs. 1%), prior cardiac surgery(40% vs. 10%), and emergency status(7% vs. 0%) compared to those without endocarditis(all p<.001). Operative mortality was higher among endocarditis patients(16% vs. 0.6%, ke those without endocarditis.Aortic root abscess is one of the most catastrophic complications of aortic valve endocarditis. Complete debridement is recommended regardless of the kind of infected lesion. A 37-year-old man with extensive aortic root abscess due to prosthetic aortic valve endocarditis was surgically treated. The main lesion was the aorto-mitral continuity extending to the commissure between the left and right coronary cusps. After debridement, the aortic annulus underneath the left coronary artery was reconstructed using a handmade aorto-mitral monobloc valve without aortic annuloplasty. This valve is required for the extensive root abscess of the left and non-coronary sinus to achieve complete debridement.
