    Abstract:
    OBJECTIVE: To evaluate the long-term clinical outcomes of patients undergoing percutaneous coronary intervention for saphenous vein graft (SVG) disease. Specifically, we compared clinical endpoints of patients who received sirolimus-eluting stents (SES) versus bare-metal stents (BMS) for SVG disease. BACKGROUND: A recent small randomized-controlled trial (RCT) reported increased mortality with the use of SES in SVG disease. METHODS: We retrospectively identified patients who underwent SES placement for a SVG lesion(s) at our institutions over a 4-year period. The procedural and medical records were reviewed to identify predetermined clinical outcomes. RESULTS: 318 patients who underwent SES placement for a SVG lesion were identified. 7 patients were lost to follow-up. 141/311 patients (45%) received SES, while 170/311 (55%) received BMS. At a mean follow-up of 34 months, there was a reduction in target lesion revascularization (TLR) (7% vs. 14%, P = 0.07) without an increased risk of mortality (6% vs. 12%, P = 0.06) in patients who received SES compared to patients who received BMS. When compared to the recent RCT's SES patients at long-term follow-up, our SES patients had significantly less mortality; rates of myocardial infarction, TLR, target vessel revascularization, and major adverse cardiac events; and were more likely to be taking dual antiplatelet and statin medications. CONCLUSION: Our results support that SES used in SVG lesions result in a reduction in TLR without an increased risk of mortality, and therefore may be an equally safe and feasible technique for revascularization with excellent long-term clinical outcomes. These patients may benefit from prolonged dual antiplatelet and statin medication regimens.
