Right Atrial Myxoma Presenting as Recurrent Ventricular Tachycardia: A Rare Clinical Presentation.

BACKGROUND

Myxomas are the most frequent primary cardiac tumors, with right atrial origin relatively uncommon. Clinical presentation varies with tumor size, mobility, and location.

CASE SUMMARY: A 34-year-old male patient presented with recurring ventricular tachycardia. Echocardiography demonstrated a large stalked right atrial mass causing right-sided chamber dilatation and severe tricuspid regurgitation. Computed tomography confirmed a calcified right atrial mass. Surgical excision of the lesion along with tricuspid valve annuloplasty was subsequently performed. Histopathology confirmed atrial myxoma with calcification and osseous metaplasia. Postoperative course was uneventful with no arrhythmic complications.

DISCUSSION: Right atrial myxomas may present unusually with ventricular arrhythmias. Calcification and osseous metaplasia are uncommon findings in cardiac myxomas. Early surgical resection remains the definitive treatment and confers excellent outcomes.

TAKE-HOME MESSAGES: Right atrial myxoma can rarely present with recurrent ventricular tachycardia alongside structural and mechanical complications. Multimodality imaging-guided surgical excision is curative and prevents life-threatening complications.
