A mass abutting the right mediastinal contour on chest X-ray (Panel A). Transthoracic echocardiography images of mass compressing the right atrium and ventricle (Panel B). An extracardiac mass was causing a significant stenosis with a peak/mean gradient pressure of 12.3/4.97 mmHg on tricuspid valve (Panel C). Selective coronary angiogram images of HSVGA in right oblique projection (Panel D). * HSVGA. HSVGA: huge saphenous vein graft aneurysm; RA: right atrium; RV: right ventricle; LA: left atrium; LV: left ventricle.

Eventually, there was a significant stenosis with a peak/mean gradient pressure of 12.3/4.97 mmHg on tricuspid valve (Fig. 1B-D). Coronary angiography showed an aneurysm of the saphenous vein graft (SVG) to the distal right coronary artery (Fig. 1D).
Chest computerized tomography images of HSVGA (Panels A and B). Extracted materials after surgery (Panels C and D). + tricuspid annulus; * thrombus. HSVGA: huge saphenous vein graft aneurysm; RA, right atrium; RV, right ventricle; LA, left atrium; LV, left ventricle.

Thorax CT examination revealed a 10.68 x 9.65 cm mass, felt to be a huge SVG aneurysm and compressing the right side of the heart (Fig. 2A and B). Fig. 2A, B, and D showed the mural thrombus of aneurysm.
