High-degree atrioventricular block in young patients often requires pacing, posing long-term risks. We present a 15-year-old athlete with sickle cell trait and high-degree atrioventricular block managed with cardioneuroablation. Post-cardioneuroablation, atrioventricular conduction normalised, and a nine-month follow-up showed no arrhythmias. This case underscores cardioneuroablation as a promising, less invasive alternative to pacing for young patients, requiring further research.
