Second Study on Cardio-neuromodulation in Humans

Different approaches to cardio-neuroablation (CNA) to treat neurally mediated syncope, sinus node dysfunction, and functional atrioventricular block have been published. Investigators have developed a more limited and specific approach of CNA, called cardio-neuromodulation (CardNM). This treatment is based on a tailored vagolysis of the sinoatrial node through partial ablation of the anterior right ganglionated plexus (ARGP); it is also based on an innovative anatomic strategy. The feasibility of CardNM has already been tested in our center in a limited first study in humans (CardNMH1), with a favorable outcome for the patients involved. The results of CardNMH1 have been submitted for publication. The purpose of this second study of CardNM in humans (CardNMH2) is to collect more procedural and clinical data in well-defined patient groups.
