Safety and Feasibility of Cardiac Electrophysiology Procedures In Ambulatory Surgery Centers.

BACKGROUND

Despite their improved safety, majority of cardiac electrophysiology procedures, including catheter ablation (CA), are presently performed in hospital outpatient departments (HODs).

OBJECTIVE

This large, multicenter study investigated the safety and outcomes associated with various cardiac electrophysiology procedures performed at 6 ambulatory surgery centers (ASCs), primarily during the COVID-19 pandemic under the CMS Hospitals Without Walls program.

METHODS

We retrospectively analyzed the outcomes from consecutive electrophysiology procedures performed in ASCs with same-day discharge, including transesophageal echocardiography (TEE), cardioversion, cardiac implantable electronic device (CIED) implantation, electrophysiology studies (EPS), and CA for atrial fibrillation (AF), atrial flutter (AFL)/supraventricular tachycardia (SVT), ventricular premature complexes (VPCs), and AV node.

RESULTS

Altogether, 4,037 procedures were performed, including 779 TEE/cardioversions (19.3%), 1,453 CIED implants (36.0%), 26 EPS (0.6%), and 1,779 CAs (44.1%) for AF (75.4%), AFL/SVT (18.8%), VPC (4.7%), and AV node (1.1%). Overall, 80.2% of CAs were for left-sided atrial arrhythmias (AF/atypical AFL) requiring transseptal catheterization. Left-sided VPC ablations (42.2%) were performed using a transseptal/retrograde approach. Adverse event rates were low, but comparable between CIED and CA (0.76% vs. 0.73%; P=0.93), as were the incidences of urgent/unplanned post-procedure hospitalization (0.48% vs. 0.45%; P=0.89), respectively. Moreover, the adverse event rates in ASCs versus HODs did not differ for CIED (0.76% vs. 0.65%; P=0.71) or CA (0.73% vs. 0.80%; P=0.79).

CONCLUSION

The results from this large, multicenter study suggest that ASCs represent a safe and effective setting to conduct a variety of cardiac electrophysiology procedures including CA. These findings bear important implications for healthcare delivery and policy.
