Abstract

OBJECTIVE: The objective of the present study was to perform a systematic review and meta-analysis of studies reporting outcomes after first- and second-generation drug-eluting stent (DES) implantation in chronic total occlusions (CTOs). BACKGROUND: The effect of second- vs first-generation DESs on the outcomes after CTO percutaneous coronary intervention (PCI) has received limited study. METHODS: As of May 2013, thirty-one published studies reported outcomes after DES implantation in CTOs: thirteen uncontrolled studies (3161 patients), three randomized (220 patients) and ten non-randomized (2150 patients) comparative studies with bare-metal stents (BMSs), and two non-randomized (685 patients) and three randomized (489 patients) comparative studies between first- and second-generation DESs. Data from the five studies comparing first with second-generation DESs were pooled using random-effects meta-analysis models. RESULTS: The median and mean duration of follow-up were 12 and 14.4 months, respectively. Compared to first-generation DESs, second-generation DESs were associated with lower incidence of death (odds ratio [OR], 0.37; 95% confidence intervals [CI], 0.15-0.91), target vessel revascularization (OR, 0.59; 95% CI, 0.40-0.87), binary angiographic restenosis (OR, 0.68; 95% CI, 0.46-1.01) and reocclusion (OR, 0.35; 95% CI, 0.17-0.71), but similar incidence of myocardial infarction (OR, 0.45; 95% CI, 0.10-1.95) and stent thrombosis (OR, 0.34; 95% CI, 0.07-1.59). CONCLUSIONS: Compared to first-generation DESs, second-generation DESs are associated with improved angiographic and clinical outcomes in CTO PCI and are the preferred stents for these challenging lesions.
