Selective Cardioneuroablation for Symptomatic Sinus Bradycardia After Bariatric Surgery: A Report on two Cases

Functional bradycardia, characterized by a heart rate below the normal range due to dysregulation of the autonomic nervous system (ANS), poses a clinical challenge with limited treatment options. Symptomatic sinus bradycardia is an uncommon but potentially significant complication following bariatric surgery. Cardioneuroablation (CNA) has emerged as a novel therapeutic intervention targeting the cardiac ANS to modulate heart rate. This case series describes two patients, with the aim of providing a simplified but successful approach with targeted partial CNA for sinus bradycardia complicating bariatric surgery.
