2. Fig 1
Preoperative electrocardiogram demonstrates atrial tachycardia with varying degrees of atrioventricular conduction. The atrial rate is 150 beats per minute.

3. Fig 2
Multiplane transesophageal echocardiogram at 92 degrees shows a large echogenic mass (white arrows) attached at the superior portion of the right atrium with partial obstruction of the superior vena cava. (LA = left atrium; RA = right atrium; SVC = superior vena cava.)

4. Fig 3
Surgical view demonstrates thickened pericardium and the yellowish-brown mass at the right atrium (white arrows). (Ao = aorta; IVC = inferior vena cava.)

5. Fig 4
Light microscopic findings show ill-defined granuloma with central caseation necrosis and infiltrations of epithelioid cells and lymphocytes consistent with tuberculosis. (Hematoxylin-eosin stain; ×100 before 49% reduction.)

6. Fig 5
Multiplane transesophageal echocardiogram after 5 months of antituberculosis medication reveals complete disappearance of the mass and normal diameter of the superior vena cava. (LA = left atrium; RA = right atrium; SVC = superior vena cava.)
