Key result
A described surgical technique allows for abscess cavity repair, annulus reconstruction, and new mitral prosthesis implantation in patients with severe myocardial calcification to decrease reoperation risk.

May inform technique selection in complex mitral reoperations with calcification; case-level evidence leaves durability and generalizability open.
Abscess resection and prosthesis reimplantation is the only effective treatment for mitral prosthesis endocarditis with extensive annular abscess, but it has high morbidity and mortality when associated with severe mitral annular calcification in the atrial and ventricular walls. We describe a technique that allows repair of the abscess cavity, reconstruction of the annulus, and implantation of a new mitral prosthesis when there is severe adjacent myocardial calcification, so decreasing the reoperation risk.

Carrascal et al. (2012) conducted a case report in Mitral prosthesis endocarditis with extensive annular abscess and severe mitral annular calcification. Abscess cavity repair, annulus reconstruction, and new mitral prosthesis implantation technique was evaluated. A described surgical technique allows for abscess cavity repair, annulus reconstruction, and new mitral prosthesis implantation in patients with severe myocardial calcification to decrease reoperation risk.
