Cardiac blood cysts are rare benign lesions typically observed in neonates and infants; persistence into adulthood is uncommon. Involvement of the tricuspid subvalvular apparatus is particularly rare. We report the case of a 47-year-old woman with a cardiac blood cyst arising from the tricuspid subvalvular apparatus.
