In post-coronary artery bypass graft (CABG) patients undergoing drug-eluting stent implantation of either the saphenous vein graft (SVG) versus the native coronary artery supplying the same myocardial perfusion territory, which option confers better clinical outcomes when both lesions are technically feasible?From 2005 to 2008 at a single medical center, a total of 178 post-CABG patients (with 241 lesions) underwent PCI due to progressive SVG disease. Of them, 23 patients (with 29 lesions) had amenable disease for PCI in both the SVG and native coronary artery matching the same myocardial perfusion territory; chronic total occlusions were excluded. All patients included in the study were treated with drug-eluting stents. Sixteen patients (19 lesions) underwent PCI of the SVG, and 9 patients (10 lesions) underwent PCI in the native vessels.Primary endpoints were in-hospital and 3-year rates of death, myocardial infarction (MI), target lesion revascularization (TLR), and target vessel revascularization (TVR). There were 2 in-hospital MIs in the SVG-treated group and 0 for the native vessel-treated group. The 3-year clinical follow-up showed 3 MIs, 2 TLRs, 4 TVRs, and 6 deaths in the SVG-treated group; only 1 MI occurred in the native-vessel treated group (P=.02). More PCIs of the SVG were performed than in the native coronary artery (19 vs 10 lesions).This small study suggests improved clinical outcomes with PCI of the native vessel, but a tendency of operators to choose PCI of the SVG instead. Large, prospective, multicenter, randomized clinical trials with long-term follow-up can validate the advantage of selecting PCI of the native vessel over the SVG when both options are available.

We compared safety and efficacy outcomes of 3 limus-based drug-eluting stents in the ‘all-comers’ PROENCY (PROmus/ENdeavor/CYpher) registry.Limited data are available on head-to-head comparisons of the everolimus-eluting stent (EES) with the zotarolimus-eluting stent (ZES) or the sirolimus- eluting stent (SES) in the treatment of patients with coronary artery disease.PROENCY was a prospective, open-label, multicenter, observational study including consecutive patients undergoing planned treatment with EES, ZES, or SES. Seventeen centers were designated to place an EES or SES, 14 other centers were designated to place EES or ZES. The primary endpoint was the composite of cardiac death, myocardial infarction, and target vessel revascularization (TVR) at 12 months. Unadjusted and propensity-adjusted outcomes were compared between groups.A total of 1921 patients were enrolled in the study from February to December 2008, of which 1704 patients received only study stents and were analyzed. At 12 months, the unadjusted major adverse event rate was significantly lower in the EES group versus the ZES group (3.1% vs 8.7%; P=.001) and the SES group (5.2% vs 9.6%; P=.01). This was mainly driven by lower TVR rates [2.6% with EES vs 8.2% with ZES [P<.001] and 4.1% with EES vs 7.0% with SES [P=.05]. Stent thrombosis rates were low and comparable. Adjusted analyses confirmed the unadjusted results.There were no differences in safety outcomes of EES, ZES, and SES at 12 months in PROENCY. However, differences in efficacy were observed between the 3 "limus"-based stents in a real-world patient population. HubMed – drug

In-stent restenosis (ISR), especially focal ISR, after percutaneous coronary intervention (PCI) remains one of the major clinical problems in the drug-eluting stent (DES) era. Several reports have revealed that excimer laser coronary angioplasty (ELCA) is useful for ISR; however, detailed findings after ELCA are unknown. Therefore, we investigated the condition of the neointima after ELCA for ISR with optical coherence tomography (OCT) and compared the OCT findings and clinical outcome between ELCA and cutting-balloon angioplasty (CBA).Twenty-one consecutive patients with focal ISR who underwent ELCA or CBA were enrolled. All patients underwent 12- to 15-month follow-up coronary angiography. OCT was performed immediately after successful PCI to evaluate the neointimal condition in the ISR lesion. We compared the following OCT parameters between ELCA and CBA groups: maximal thickness of remaining in-stent neointima (MTN), number of tears, minimum lumen dimension (MLD), and minimum lumen area (MLA). We also evaluated clinical outcomes, including target vessel revascularization, acute myocardial infarction, death, and stent thrombosis.MLA in the ELCA group (n = 10) was significantly larger than in the CBA group, and number of tears in the ELCA group was significantly lower than in the CBA group. A trend was shown toward lower TLR with ELCA versus CBA (10.0% vs 45.5%).OCT immediately after ELCA for ISR lesions revealed larger lumen area and smaller number of tears compared with CBA, which may support favorable effects of ELCA for focal ISR.
