Neurally Mediated Syncope Clinical Trial
Official title:
Efficacy of Transcatheter Ablation of Ganglionic Plexuses (Cardioneuroablation) in Right Atrium in Patients With Asystolic Neuromediated Syncope
Multicenter Italian interventional "proof of efficacy" clinical trial that aims to evaluate the incidence of asystolic pauses and heart rate in patients with CNS who performed severe CNA identified through asystolic pauses identification by implantable loop recorder. The study is independent, "investigator-initiated," sponsored by a nonprofit scientific association called the Italian Multidisciplinary Group for the Study of Syncope (GIMSI).
The so called "Cardioneuroablation (CNA)" focused on the endocardial ablation of atrial ganglionated plexi has proven to be efficacy in patients affected by neuro-mediated cardioinhibitory syncope (NCS). No center currently has sufficient case series to establish long-term efficacy and safety results, for which a multicenter interventional study is therefore needed. The aim of the study will be to evaluate the efficacy and safety of CNA focused in NCS patients. The ablation procedure, consists of radiofrequency delivering at right atrial anatomic sites where the underlying presence of GP clusters is regarded as highly probable: 1) the inferior-posterior area (first ablation site): inferior right GP placed between inferior vena cava, coronary sinus ostium and near the atrio-ventricular groove, 2) the superior-posterior area (second ablation site): superior right atrial GP, adjacent to the junction of the superior vena cava and the posterior surface of RA. ;
