PCI center volume was categorized based on annual number of interventions: low (&lt;\u2009200), intermediate (200\u2013499), and high (\u2265\u2009500). Operator experience was assessed by years of practice (low [&lt;\u20095] and high [\u2265\u20095]) and the number of PCI cases performed annually (low [&lt;\u200975] and high [\u2265\u200975]). The evaluated PCI outcomes were: PCI failure; procedural complications; PCI\u2010related in\u2010hospital mortality; 1 year post\u2010intervention all\u2010cause mortality.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 19,701 patients who underwent PCI were included in the analysis, of whom 17,432 had follow\u2010up data available after 1 year. Of these, 58.1% presented with either ST\u2010elevation or non\u2010ST elevation myocardial infarction\/unstable angina, while 41.9% had stable CAD. Nearly half of the patients had triple\u2010vessel or left\u2010main disease, and 8.7% presented with cardiogenic shock. The percent with PCI failure, procedural complications, PCI\u2010related in\u2010hospital death, and 1\u2010year all\u2010cause mortality were 4.9%, 5.1%, 2.7%, and 11.8%, respectively. Despite patients in higher\u2010risk profiles being treated at high\u2010volume PCI centers and by experienced operators, there were no significant differences in PCI failure, PCI\u2010related in\u2010hospital mortality nor 1\u2010year all\u2010cause mortality compared to those treated at low or intermediate volume PCI centers. However, high\u2010volume PCI centers had procedural complications more frequently (4.7%) than did intermediate (3.9%) and low\u2010volume (2.5%) centers (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). After adjusting for confounding factors, no significant associations were found between PCI center volume and PCI outcome. Similarly, no significant relationship was found between operator experience and procedural complications, nor 1\u2010year all\u2010cause mortality. Nevertheless, operators with more years of practice were associated with lower PCI\u2010related in\u2010hospital mortality (odds ratio [95% CI] of 0.75 (0.57, 0.98); <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.038). Additionally, operators conducting a higher number of PCIs annually tended to have less PCI failures (odds ratio [95% CI] of 0.76 (0.57, 1.01); <jats:italic>p<\/jats:italic>\u2009=\u20090.062).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A center's PCI volume did not significantly impact PCI outcome.
