Blood Cyst of Subvalvular Apparatus of the Mitral Valve in an Adult

ABSTRACT

Blood cysts of the heart are rare benign tumors, usually involving the cardiac valves. They are found mainly in the first month of life and in children; and are rarely seen in adults. Here, we report a case of a blood cyst on the subvalvular apparatus of the mitral valve, which was incidentally discovered during chest computed tomography in a 47-year-old man. To the best of our knowledge, this is the first reported case of blood cyst of the heart in an adult in Korea.
