Update on Cardiac Catheterization in Patients With Prior Coronary Artery Bypass Graft Surgery.

ABSTRACT

Patients who undergo coronary bypass graft surgery often require subsequent cardiac catheterization and repeat coronary revascularization. Saphenous vein graft lesions have high rates for distal embolization that can be reduced with use of embolic protection devices. They also have high restenosis rates, which are similar with drug-eluting and bare-metal stents. Percutaneous coronary interventions of native coronary arteries is generally preferred over saphenous vein graft interventions, but can often be complex, requiring expertise and specialized equipment. Prolonged dual-antiplatelet therapy and close monitoring can help optimize subsequent clinical outcomes.
