Background: The autonomic nervous system (ANS) plays a significant role in atrial fibrillation (AF). Catheter ablation (CA) is a well-established treatment method for AF and significantly affects the ANS, including baroreceptor (BR) function. However, little is known about the changes in BR function caused by radiofrequency (RF) or cryoballoon energy (CB) and its impact on future AF recurrences.

Cardioneuroablation has emerged as a potential alternative to cardiac pacing in selected cases with vasovagal reflex syncope, extrinsic vagally induced sinus bradycardia-arrest or atrioventricular block. The technique was first introduced decades ago, and its use has risen over the past decade. However, as with any intervention, proper patient selection and technique are a prerequisite for a safe and effective use of cardioneuroablation therapy.

In an experimental study of two-branched beams bent transversely about the major stiffness axis, the elastic critical load from the lateral-torsional buckling condition was determined. The tests were conducted on simply supported two-branch beam models with a built-up section consisting of two cold-formed channel members (2C) bolted back-to-back. The bolts were located at the mid-height of the built-up cross-section.

Article Synopsis
  • A study was conducted to evaluate the success and outcomes of electroanatomical-guided cardioneuroablation (EACNA) in treating patients with vagally induced atrioventricular blocks (VAVBs).
  • The results showed a high acute procedural success rate of 96.2%, but 14% of patients experienced recurrence of AVB or new syncopal episodes during a follow-up period of approximately 300 days.
  • The findings suggest that EACNA is a promising option for patients with VAVB, but further research is needed to explore its effects on daytime symptom burden.
