Historically, the availability of on\u2010site cardiothoracic surgery (CTS) has been considered an important safety requirement. However, contemporary advances in ablation techniques and peri\u2010procedural care have improved procedural safety, and real\u2010world data evaluating the impact of on\u2010site CTS availability in current practice remain limited.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n We analyzed the National Readmissions Database (NRD) from 2016 to 2021 to identify adults undergoing catheter ablation for AF. Hospitals were classified based on the presence of on\u2010site CTS, defined by the performance of coronary artery bypass graft surgery. Baseline characteristics were compared between groups. Multivariable logistic regression was used to assess the association between on\u2010site CTS availability and in\u2010hospital complications, mortality, discharge disposition, and 30\u2010day all\u2010cause readmissions, adjusting for demographic and clinical covariates.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Among 81\u2009471 patients undergoing AF ablation, 3.3% were treated at centers without on\u2010site CTS and 96.7% at centers with CTS. Patients treated at centers without CTS were older, more frequently female, and had a higher comorbidity burden, including greater thromboembolic risk. After multivariable adjustment, on\u2010site CTS availability was not independently associated with in\u2010hospital mortality, cardiac perforation, pericardiocentesis, need for open heart surgery, vascular, pulmonary, or neurological complications, discharge to home, or 30\u2010day readmissions.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n In this large, contemporary national cohort, the availability of on\u2010site cardiothoracic surgery was not independently associated with improved peri\u2010procedural or short\u2010term outcomes following AF ablation.<\/jats:p>\n
