Cardioneuroablation: Fragmented Atrial Potentials, Intracardiac Echocardiography and Computed Tomography

Sponsor: Centre of Postgraduate Medical Education

Summary

Cardioneuroablation (CNA) is a new method for the treatment of asystolic reflex syncope, however, optimal methods for identification of presumed sites of ganglionated plexi (GP), which are the target for CNA and are located in the epicardial fat, have not yet been established. This study will compare the accuracy of three methods used for identification of these areas: intracardiac recordings of fractionated atrial electrograms, intracardiac echocardiography and computed tomography. The study group will consist of 100 patients undergoing CNA in our institution. The procedure will be performed in a standard manner with the use of extracardiac vagal stimulation as the intraprocedural end-point. Correlation between the three methods used for localisation of optimal sites for CNA as well as their predictive value for achieving effective CNA will be computed.
