A Case of Myxoma Originating from the Anterior Leaflet of the Mitral Valve / 日本心臓血管外科学会雑誌

ABSTRACT

We reported a rare case of myxoma originating from the anterior leaflet of the mitral valve. A 65-year-old woman was admitted with sympotomes of easily fatigability and palpitation. On auscultation, a grade II/IV systolic murmur was audible at the apex. Echocardiography demonstrated a dense mass arising from the anterior mitral leaflet. The tumor (16×13×10mm in size) was resected from the anterior leaflet of the mitral valve. There was no definite evidence of a tumor stalk on the mitral valve nor valve regurgitation after the operation. Microscopically, polyhedral cells were recognized, indicating myxoma. The postoperative course was uneventful and no recurrence has been noticed during the past 6 years.
