Aortic valve replacement with sutureless Perceval S valve: A case report of aortic root homograft failure in the setting of Streptococcus constellatus endocarditis

Abstract

Background: Surgery for failed homograft aortic root replacement with extensive calcification in the setting of endocarditis alone is very challenging.

Case summary: We report the case of redo aortic valve replacement and mitral valve replacement, in a 39 years old presenting with a rare Streptococcus constellatus endocarditis of a previously implanted homograft root and native mitral valve, where conventional valve replacement proved nonfeasible. S. constellatus had caused severe tissue destruction and the extensive calcification in the homograft prevented conventional valve replacement with sutures. In this case, a sutureless valve provided a useful alternative surgical strategy.

Discussion: We consider heavily calcified failed homografts to be a good indication for sutureless (rapid deployment) valves.
