Adjusted rates of in\u2010hospital major adverse cardiac\/cerebrovascular events (MACCE) were not significantly different with RASER. However, there were higher odds of arterial complications (OR 3.23, 95% CI: 1.58\u20136.61), slow flow (OR 3.50, 95% CI: 1.29\u20139.55), and shock induction (OR 9.66, 95% CI: 3.44\u201327.06).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>RASER atherectomy use in complex PCI is associated with higher risk baseline and procedural characteristics.
