A case of biatrial mass mimicking myxoma with rheumatic mitral stenosis with regurgitation of moderate severity

Abstract

Atrial masses are uncommon and mainly consist of tumours, thrombus and vegetation.1 Cardiac myxoma is the most common type of benign cardiac tumour and accounts for 30–50% of all primary tumours of the heart.2 Most of them occur in the left atrium, but the occurrence of biatrial mass/myxoma or concomitant left atrial mass with rheumatic valvular disease is uncommon. We describe a case of biatrial mass mimicking myxoma with rheumatic mitral stenosis. A 40-year-old woman presented with exertional dyspnoea and palpitation was diagnosed to have biatrial mass with rheumatic mitral stenosis and underwent a successful biatrial mass excision and valve replacement.
