Pulmonary Vein Isolation (PVI) Combined With Renal Denervation (RDN) in Atrial Fibrillation (AF) and Hypertension (HTN)

Evaluation of the Safety and Efficacy of Pulmonary Vein Isolation (PVI) Combined With Renal Denervation (RDN) in Patients With Atrial Fibrillation (AF) and Hypertension (HTN)

The close relationship between the increase of sympathetic tension, AF, and HTN cannot be ignored. In addition, the significant failure rate of PVI (20-50%) in the treatment of AF makes it very necessary to explore the effect of RDN on AF. Therefore, this study aims to compare the effects and safety of PVI alone and PVI combined with RDN with AF combined with HTN, which will open a new chapter for PVI combined with RDN in the treatment of AF.
