Cardiac myxoma originating from the anterior mitral leaflet.

Cardiac myxoma arising from the anterior mitral leaflet is extremely rare. A 47-year-old Taiwanese male was found to have a 5 x 4 x 3 cm myxoma originating from the atrial side of the anterior mitral leaflet using transesophageal echocardiography. The tumor was successfully treated by surgical excision. The resected tumor was a well-defined encapsulated mass with a broad-base stalk arising from the anterior mitral leaflet. To detect the early recurrence, a semiannual follow-up examination using transesophageal echocardiography is needed.
