Résumé
Aortic homografts have been used in young patients requiring aortic valve replacement. Currently, these grafts 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 to 2019 were included. Outcomes of interest included all-cause mortality and aortic valve reoperation, studied over a median follow-up duration of 19 years. In all, 252 patients with a mean age of 49 years were included. Infective endocarditis was the primary indication for surgery in 95 patients (38%). The endocarditis group, compared with the no-endocarditis group, had a higher prevalence of New York Heart Association class III-IV (56% vs 26%), chronic kidney disease (22% vs 1%), prior cardiac surgery (40% vs 10%), and emergency status (7% vs 0%; all P < .001). Operative mortality was higher among endocarditis patients (16% vs 0.6%, P < .001), which persisted after risk adjustment. Among patients who survived to discharge, however, there was no difference in long-term survival between the endocarditis group and no-endocarditis group. Overall survival and freedom from reoperation were 88.3% and 80% at 15 years and 87.2% and 78% at 25 years, respectively. Indications for reoperation included structural valve deterioration (83%), endocarditis (12%), and mitral valve disease (5%). Reoperative mortality occurred in 2 patients (4.9%). Aortic homografts are associated with good long-term survival and admissible freedom from reoperation. Operative mortality is high among patients with endocarditis; however, for those who survive to discharge, long-term survival and durability are the same as for patients without endocarditis.

BACKGROUND
BACKGROUND
Aortic homografts have been used in young patients requiring aortic valve replacement. Currently, these grafts 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.
METHODS
METHODS
All adult patients undergoing aortic homograft implantation at a single institution from 1992 to 2019 were included. Outcomes of interest included all-cause mortality and aortic valve reoperation, studied over a median follow-up duration of 19 years.
RESULTS
RESULTS
In all, 252 patients with a mean age of 49 years were included. Infective endocarditis was the primary indication for surgery in 95 patients (38%). The endocarditis group, compared with the no-endocarditis group, had a higher prevalence of New York Heart Association class III-IV (56% vs 26%), chronic kidney disease (22% vs 1%), prior cardiac surgery (40% vs 10%), and emergency status (7% vs 0%; all P < .001). Operative mortality was higher among endocarditis patients (16% vs 0.6%, P < .001), which persisted after risk adjustment. Among patients who survived to discharge, however, there was no difference in long-term survival between the endocarditis group and no-endocarditis group. Overall survival and freedom from reoperation were 88.3% and 80% at 15 years and 87.2% and 78% at 25 years, respectively. Indications for reoperation included structural valve deterioration (83%), endocarditis (12%), and mitral valve disease (5%). Reoperative mortality occurred in 2 patients (4.9%).
CONCLUSIONS
CONCLUSIONS
Aortic homografts are associated with good long-term survival and admissible freedom from reoperation. Operative mortality is high among patients with endocarditis; however, for those who survive to discharge, long-term survival and durability are the same as for patients without endocarditis.
