Cardioneuroablation: Three different approaches

Abstract

Cardioneuroablation (CNA) is an emerging therapy for patients with vasovagal syncope with predominant cardioinhibitory responses. The procedure targets the neuromyocardial connections localized in specific regions of the right and left atrium as well as the adjacent ganglionated plexi (GP) providing parasympathetic innervation to the sinus and atrioventricular nodes. The target regions for CNA can be determined with various techniques, which result in heterogenous procedural approaches and endpoints in different centers specialized in this procedure. In this review we summarize the rationale and details of the procedural approach for three different techniques for CNA, namely: CNA controlled by extra-cardiac vagal stimulation, CNA guided by analysis of fractionated electrograms, and an anatomical approach to CNA.
