Zusammenfassung:Whether saphenous vein grafts (SVGs) should be occluded after successful chronic total occlusion (CTO) percutaneous coronary intervention (PCI) of the corresponding native vessel remains controversial. We analyzed the clinical and angiographic characteristics and procedural outcomes of 51 patients who underwent SVG occlusion following successful CTO-PCI of the corresponding native vessel between 2015 and 2022 at 14 centers. Mean patient age was 71 ± 8 years and 80% were men. The most common CTO target vessel was the right coronary artery (41%), followed by the left circumflex (37%). Retrograde crossing through the SVG was the successful crossing strategy in 40 cases (78%). SVG occlusion was achieved with coils (1.9 ± 1.0) in 35 of 51 patients (69%) and vascular plugs in the other 16 cases (31%). All procedures were technically successful and the SVG was occluded completely (TIMI 0 flow) in 38 of the cases (75%), with the remaining cases having TIMI 1 flow. Follow-up was available for 37 patients (73%); during a mean follow-up of 312 days from CTO-PCI, the incidence of target-lesion failure due to restenosis was 5.4% (n = 2) with no other major events reported. Following native vessel CTO-PCI, SVG occlusion is often performed and is associated with favorable mid-term outcomes.
