A rapidly growing tricuspid valve myxoma can mimic a thrombus after tricuspid annuloplasty, requiring surgical excision for definitive diagnosis.

May represent myxoma mimicking thrombus post-annuloplasty; extends differential for rapidly growing masses but remains hypothesis-generating.
A 55-year-old man with massive pulmonary thromboembolism underwent thrombolysis, pulmonary artery embolectomy and tricuspid annuloplasty. Nine months later, a mobile echogenic intra-cardiac mass was found in the tricuspid valve. Because the patient had undergone annuloplasty, thrombosis was suspected as the most likely diagnosis and thrombolytic therapy was instituted. However, the size of the cardiac mass did not change and after surgical excision the mass was found to be a myxoma. Cardiac valvular tumors are uncommon and when they occur they are usually slow growing fibroelastomas. In this case, the rapid growing cardiac myxoma on the tricuspid valve was found after the occurrence of pulmonary thromboembolism. To our knowledge, this is first reported case of tricuspid valve myxoma in Korea.

Park et al. (2011) conducted a case report in Tricuspid Valvular Myxoma (n=1). Surgical excision was evaluated on Histopathological diagnosis of the excised mass. Surgical excision of a rapidly growing intracardiac mass on the tricuspid valve, which was unresponsive to thrombolysis, revealed it to be a rare tricuspid valvular myxoma.
