Isolated tricuspid valve repair after metastatic tumor resection.

Abstract

Isolated tricuspid valve repairs are performed in adults most commonly as a result of infective endocarditis, traumatic injury, rheumatic involvement, and ischemia. The use of neochordae made from polytetrafluoroethylene, being widespread in mitral valve operations, is gaining ground in tricuspid valve repair. We report a very rare case that describes isolated tricuspid valve repair using neochordae after resection of a right ventricular tumor involving the tricuspid valve. The tumor isolated was metastatic teratoma in a patient with growing teratoma syndrome. We further describe our technique of tricuspid neochord implantation and the rationale behind the repair.
