Two cases of left atrial myxoma originating from mitral annulus

: We experienced two cases of left atrial myxoma originating from mitral annulus. Mitral valve replacement and mitral valvulo-annuloplasty were performed in each case, because of the presence of mitral leaflet defect due to removal of the myxoma. Two dimensional echocardiography was a useful method to confirm the location and decide the surgical approach.
