title: Retrograde fractional flow reserve and recanalization of a chronic total occlusion of a saphenous venous graft.
abstract: Chronic total occlusion (CTO) of the coronary artery represents a difficult group of lesions for percutaneous interventions. Conventionally, antegrade approach has been used to open these lesions, but recent literature provides evidence for the utility of retrograde approach in cases where initial antegrade approach is either not feasible or fails to recanalize the target vessel. This report illustrates retrograde CTO recanalization of saphenous vein graft (SVG) with fractional flow reserve utilization to determine ischemia in the territory of occluded SVG.
