Key result
Surgical excision of a tricuspid papillary muscle blood cyst completely resolves symptoms while preserving valve function.
Why the study?
Cardiac blood cysts rarely persist into adulthood and involvement of the tricuspid subvalvular apparatus is particularly rare.

Supports valve-sparing excision for rare tricuspid blood cysts; leaves open need for prospective outcome data.
Lee et al. (2026) conducted a case report in Cardiac blood cyst (n=1). Surgical excision was evaluated on Resolution of symptoms and preservation of valve function. Surgical excision of a rare cardiac blood cyst arising from the tricuspid papillary muscle resulted in complete resolution of symptoms and preserved valve function at 4 months.
