Cardiac myxomas are the most common benign primary cardiac tumors, typically arising from the interatrial septum. Rarely, they may demonstrate complex attachment involving both the interatrial septum (IAS) and mitral valve apparatus. We report a 60-year-old female presenting with exertional dyspnea. Echocardiography revealed severe mitral regurgitation, pulmonary hypertension, and a pedunculated mass (~1.3 × 1.5 cm) attached to the base of the IAS and anterior mitral leaflet (AML). The patient underwent successful mitral valve replacement with complete tumor excision.Histopathological examination confirmed cardiac myxoma. Postoperative imaging showed a well-functioning prosthetic valve with no residual mass. This case highlights a rare presentation of myxoma with dual attachment and its surgical implications.
