Clinical controversy: methodology and indications of cardioneuroablation for reflex syncope

Abstract

Observational studies and a recent randomized controlled trial have provided some evidence that cardioneuroablation (CNA) may prevent syncope recurrence in patients affected by cardioinhibitory reflex syncope during the first 2 years following the procedure. Nevertheless, many issues concerning clinical indications, methodology, and long-term results remain unresolved. These issues constitute the background of this manuscript in which pioneers in CNA and experts in syncope debated critical aspects aimed at finding agreement or, if not possible, that highlighting the controversies could be addressed in future studies.
