Giant Left Atrial Myxoma Found with Congestive Heart Failure；Report of a Case

はじめに　左房粘液腫は比較的まれな疾患であるが，巨大になると僧帽弁へ陥頓してショック状態に陥ったり，僧帽弁狭窄や閉鎖不全を合併して心不全を起こしたりすることが報告されている1）．われわれは，巨大左房粘液腫により高度の僧帽弁狭窄兼閉鎖不全を伴って心不全を呈した症例に対し，摘出術を施行して良好な結果を得たので報告する．

We report a case of giant left atrial myxoma in a 52-year-old woman who developed congestive heart failure. By echocardiography, not only the myxoma but moderate degree of mitral and tricuspid regurgitation was also found. The tumor was extensively attached to the left atrial endocardium, and was excised completely together with the endocardium. No valve surgery was added. Postoperative echocardiography showed no myxoma and no mitral valve regurgitation. She was discharged in good condition on postoperative day 14.
