Abstract
BACKGROUND: There are limited contemporary data on the impact of success vs. failure on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI).
METHODS: We conducted a systematic review and a meta-analysis of contemporary studies that compared the outcomes in patients who underwent successful vs. failed contemporary (2010 onwards) CTO PCI. We performed a sensitivity analysis limited to studies that started enrollment after the publication of the hybrid algorithm in 2012.
RESULTS: We included five studies with a total of 6,084 patients (successful CTO PCI n = 4,861, failed CTO PCI n = 1,223). During a median follow-up time of 12 months (range 6-60 months), successful CTO PCI was associated with a lower risk of major adverse cardiovascular events [OR: 0.61, 95% CI (0.41, 0.92), p = 0.02, I(2) = 63%] and all-cause death [OR: 0.57, 95% CI (0.33, 0.99), p = 0.05, I(2) = 60%]. Both groups had similar risk of myocardial infarction (MI) [OR 0.69, 95% CI (0.43, 1.10), p = 0.38, I(2) = 80%], target vessel revascularization (TVR) [OR: 0.56, 95% CI (0.25, 1.27), p = 0.17, I(2) = 80%], and stroke [OR: 0.52, 95% CI (0.14, 1.91), p = 0.33, I(2) = 0%].
CONCLUSION: In contemporary practice, successful CTO PCI was associated with a lower incidence of MACE driven by lower all-cause mortality compared with failed CTO PCI at a median follow-up of 1 year.
