Key result
Complete surgical excision with mitral valve replacement successfully resolves complex dual-attachment left atrial myxoma.
Why the study?
Left atrial myxomas with complex dual attachment to both the interatrial septum and mitral valve apparatus are rare and pose diagnostic and therapeutic challenges.
Case Report (n=1)
This case report highlights a rare presentation of a cardiac myxoma with dual attachment to the interatrial septum and mitral valve, emphasizing the need for comprehensive imaging and surgical intervention including valve replacement.
Supports feasibility of excision plus valve replacement in rare dual-attachment myxomas; leaves open generalizability and long-term outcomes.
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.

Das et al. (2026) conducted a case report in Cardiac myxoma with complex attachment (n=1). Mitral valve replacement and tumor excision was evaluated on Surgical outcome and symptom resolution. Complete surgical excision and mitral valve replacement successfully treated a rare pedunculated left atrial myxoma with complex dual attachment to the interatrial septum and anterior mitral leaflet.
