“…Ellis et al 17 demonstrated that the disease in saphenous vein grafts has a rapidly progressive character, resulting, in large part, from the evolution of the disease in untreated segments, and that the occurrence of TVR following the intervention in saphenous grafts after the first year may occur more commonly in untreated locations, rather than in the target lesion. Restenosis and progression of atherosclerotic disease are the causes of long-term failure of PCI-Saph, 17,18 which could explain the unfavorable evolution in both groups and the higher incidence of TVR in the Ostium group.…”

Background: Little is known about the late clinical outcomes of patients undergoing saphenous vein graft percutaneous coronary intervention (SVG-PCI), and there are controversies regarding the role of lesion location (aorto-ostial or graft body). Methods: Single-center registry including patients undergoing SVG-PCI between 2006 and 2011. Aorto-ostial lesion was defined as a lesion within the first 8 mm of the graft; graft body lesion was defined as a lesion located in the remaining portions of the graft. Interventions approaching only the distal anastomosis or the native coronary bed were excluded. We evaluated the rates of major adverse cardiac events (MACE), death, myocardial infarction (MI), and target vessel revascularization (TVR) between the groups. Results: One hundred and ninety-five patients were evaluated, 69 in the Aorto-Ostial Group and 126 in the Graft Body Group. Mean age was 69.6 ± 10.2 years, 41% were diabetic, 65.1% had acute coronary syndromes and most of them were treated with bare metal stents (82.5%). There was no statistical difference between groups for most of the characteristics evaluated. In the late follow-up, the TVR rate (50.8% vs. 22%; P = 0.03) was greater in the Aorto-Ostial Group. The MACE rate (67.7% vs. 63.3%; P = 0.33), death (31.7% vs. 35.6%; P = 0.95) and MI (55% vs. 42%; P = 0.64) were similar between the two groups. Conclusions: This population included a high-risk subgroup,
