Percutaneous coronary intervention of saphenous vein grafts: where do we stand? (2018)
Journal Article
Bulluck, H., Bagur, R., & Mamas, M. A. (2018). Percutaneous coronary intervention of saphenous vein grafts: where do we stand?. EuroIntervention, 14(2), 142-143. https://doi.org/10.4244/EIJV14I2A22

Saphenous vein grafts (SVG) are known to be more susceptible to accelerated atherosclerosis than native coronary arteries1. Accelerated atherosclerosis in SVG develops from resident foam cells, which then undergo apoptosis to form necrotic cores1. Th...
