We describe endoscopic-assisted minimally invasive resection of a blood cyst originating from the papillary muscle that caused severe mitral regurgitation and necessitated mitral valve replacement in an active adult woman, as well as a review of the relevant literature. An endoscopic view increases the visibility of the surgical target and facilitates a precise observation of the tumour and dissection at the appropriate layer. The On-X mechanical valve was chosen for mitral valve repair to minimize thromboembolic risk. This patient additionally benefited from endoscopic-assisted right minithoracotomy in terms of both cosmetic and functional aspects.
