Key Words: Myxoma Superior vena cava Transoesophageal echocardiography
Transoesophageal echocardiography in a 30-year-old man with systemic venous hypertension showed a right atrial myxoma extending to superior vena cava (Fig. 1)
. Colour flow showed a trickle of venous return to superior vena cava. Injection of contrast in right arm vein showed obstruction of superior vena cava (Fig. 2) with collaterals.

Arising from the right atrial side of the septum, it extended to superior vena cava. After dissecting from the walls of the vena cava, it was excised and the defect closed by dacron patch. Histology confirmed myxoma. Myxoma presenting as superior vena caval obstruction is uncommon.
