Right Ventricular Myxoma Mimicking Heart Failure

A 41-year-old woman presented with chest pain and dyspnea progressively worsening over a year. Examination revealed an ejection systolic murmur, and imaging identified the right ventricular mass, suspected to be a myxoma.

Transthoracic echocardiography revealed a right ventricular echogenic mass with severe tricuspid regurgitation, confirmed using computed tomography and magnetic resonance imaging. The patient underwent surgical excision of the mass with tricuspid valve replacement. Histopathologic examination confirmed a myxoma. Postoperatively, the patient required pacemaker implantation but showed considerable symptomatic improvement with no recurrence on follow-up.

Myxomas are the most common primary cardiac tumors in adults. Multimodal imaging is crucial for diagnosis and treatment planning. Complete surgical resection can achieve optimal outcomes.
