Destructive Aorto-Mitral Endocarditis: Two Valves for One Annulus.

Surgery for endocarditis of the aorto-mitral continuity can be a challenge in case of extensive tissue destruction. We report two cases of a modified monobloc reconstruction of the aortic and mitral valves and of the aorto-mitral fibrous body. Two valve bioprostheses were sutured to each other and implanted as a composite graft. A pericardial patch sutured to the valves was employed to reconstruct both the noncoronary sinus and the left atrial roof. This technical adjustment allows adaptation to variable anatomical conditions in these particularly difficult cases.
