We aimed to describe the clinical characteristics and outcomes of patients who underwent atherectomy at the time of percutaneous coronary intervention in centers with on-site surgical centers (SCs) versus nonsurgical centers (NSCs). Patients treated with coronary atherectomy between January 1, 2006, to December 31, 2019, from the British Cardiovascular Society Intervention (BCIS) registry were included. Primary outcomes were in-hospital all-cause mortality and major adverse cardiovascular and cerebrovascular events. A total of 20,833 patients were treated with coronary atherectomy, of which 7,983 (38%) were performed at NSC. The proportion of coronary atherectomies performed in NSC increased from 12.5% in 2006 to 42% in 2019. Compared with patients treated at SC, patients treated in NSC were older (mean age 75.1 ± SD years vs 74.2 ± SD, p <0.001), but had comparable prevalence of hypertension (NSC 73.9% vs SC 72.8%, p = 0.085), diabetes mellitus (NSC 32.2% vs SC 31.6%, p = 0.43) and renal disease (NSC 6.0% vs SC 6.0%, p = 0.99). Intracoronary imaging was used more often in NSC than SC (22.3% vs 19.4%, p <0.001). After adjustment, the odds of in-hospital mortality (odds ratios [OR] 0.76, 95% confidence intervals [CI] 0.50 to 1.16), major adverse cardiovascular and cerebrovascular events (OR 0.80, 95% CI 0.53 to 1.21), emergency coronary artery bypass graft (OR 0.49, 95% CI 0.15 to 1.57), major bleeding (OR 0.67, 95% CI 0.36 to 1.24) and coronary perforation (OR 1.07, 95% CI 0.97 to 1.43) in NSC were comparable with SC. In conclusion, coronary atherectomy in hospitals with off-site surgical cover has become more frequent, with no association with poorer outcomes, compared with hospitals with on-site surgical cover.
