Why the study?
Patients with vagally mediated functional atrioventricular block can be severely symptomatic and refractory to conventional therapies, prompting the need to evaluate cardioneuroablation as a potential management strategy.
Does cardioneuroablation improve symptoms in patients with vagally mediated functional atrioventricular block?

This review discusses the potential of cardioneuroablation as a treatment strategy for patients with symptomatic, refractory vagally mediated functional atrioventricular block.
Cardioneuroablation may offer an option for refractory vagally mediated AV block; leaves open need for randomized confirmation.
An increase in parasympathetic tone may be the main cause of some transient or permanent atrioventricular block cases. Some of these patients, defined as vagally mediated functional atrioventricular block, may be severely symptomatic and refractory to conventional therapies and may necessitate cardiac pacing. Cardioneuroablation is a relatively new strategy for management of patients with excessive vagal activation based on radiofrequency catheter ablation of main ganglionated plexi around the heart. Present review was dedicated to discuss potential usage of cardioneuroablation in patients with vagally mediated functional atrioventricular block.
