Key result
Retrograde SVG CTO recanalization with FFR successfully determines ischemia in the occluded territory.
Why the study?
Retrograde approach for recanalization of chronic total occlusion in saphenous vein grafts is an alternative when antegrade approach is not feasible or fails, but its application with fractional flow reserve assessment is not well illustrated.
Case Report
Demonstrates the utility of a retrograde approach combined with fractional flow reserve for recanalizing chronic total occlusions in saphenous vein grafts.
Supports feasibility of retrograde SVG CTO recanalization with FFR; hypothesis-generating and should not yet change practice.
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.

Singla et al. (2011) conducted a case report in Chronic total occlusion of a saphenous vein graft. Retrograde CTO recanalization with fractional flow reserve was evaluated. Retrograde recanalization of a chronic total occlusion in a saphenous vein graft with fractional flow reserve utilization successfully determined ischemia in the occluded territory.
