Baseline covariates associated with ELCA use were age, BMI, number of lesions, CTO or restenosis attempted and history of prior MI, CABG or PCI. Procedural co\u2010variates associated with ELCA were the use of glycoprotein inhibitors, intravascular imaging, rotational atherectomy, cutting balloons, microcatheters and intra\u2010aortic balloon pumps. Adjusted rates of in\u2010hospital major adverse cardiac\/cerebrovascular events (MACCE) or its individual components (death, peri\u2010procedural MI, stroke and major bleed) were not significantly altered by the use of ELCA. However, there were higher odds of dissection (OR 1.52, 95% CI 1.17\u20131.98), perforation (OR 2.18, 95% CI 1.44\u20133.30), slow flow (OR: 1.67, 95% CI 1.18\u20132.36), reintervention (OR: 2.12, 95% CI 1.14\u20133.93) and arterial complications (OR: 1.63, 95% CI 1.21\u20132.21).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>ELCA use during complex PCI is associated with higher risk baseline and procedural characteristics.
