Calcified left atrial myxoma with floppy mitral valve

SUMMARY A heavily calcified left atrial myxoma in a man aged 53 was diagnosed from the plain chest x-ray film and confirmed by echocardiography. There was also moderate mitral regurgitation caused by a floppy mitral valve. Before a systemic embolus is considered to have arisen from a floppy mitral valve, echocardiography must be performed. Myxomata of the left atrium usually present with the features of mitral valve obstruction, systemic emboli, or constitutional symptoms (Goodwin, 1963). Mitral regurgitation is a rare presenting feature (Penny et al., 1967). We report the case of a patient who presented with cerebral embolism and the signs of mitral regurgitation, in whom a calcified left atrial myxoma was found by x-ray film and echocardiography.
