Retrograde approach to coronary chronic total occlusion via an occluded saphenous bypass graft: a case report

Abstract

Retrograde coronary intervention of chronic total coronary occlusion remains challenging. We describe a successful retrograde intervention of chronically occluded right coronary artery ostium via an occluded vein graft. An occluded saphenous vein graft can be a useful means to access the distal coronary bed, enabling delivery of retrograde percutaneous coronary intervention (PCI) equipment.
