SVG (saphenous vein graft) to obtuse marginal (OM) branch

svg-om

Coronary angiogram in a post coronary artery bypass (CABG) person. Sternal wires indicate that post CABG status. Catheter tip can be seen engaged in the ostium of the saphenous vein graft (SVG) in the ascending aorta. Part of the catheter in the descending aorto is also visible as it is a trans femoral coronary angiogram. SVG graft is nicely visualized through its whole length up to its anastamosis on to the obtuse marginal (OM) branch of left circuflex coronary artery. Faint retrograde filling into the proximal part of OM is visible as well as good filling into the distal branches.
