Insights
Cardioneuroablation successfully treated high-degree atrioventricular block in a young athlete with sickle cell trait. This less invasive procedure normalized heart conduction, offering a promising alternative to long-term pacing.
Area of Science:
- Cardiology
- Electrophysiology
Background:
- High-degree atrioventricular block in young individuals presents significant challenges, often necessitating permanent pacing with associated long-term risks.
- Sickle cell trait, while generally benign, can occasionally be associated with cardiac complications.
Purpose of the Study:
- To evaluate the efficacy of cardioneuroablation in managing high-degree atrioventricular block in a young patient with sickle cell trait.
- To explore cardioneuroablation as a less invasive alternative to traditional pacing strategies.
Main Methods:
- A case study of a 15-year-old male athlete with symptomatic high-degree atrioventricular block and confirmed sickle cell trait.
- The patient underwent a novel cardioneuroablation procedure to address the atrioventricular conduction abnormality.
Main Results:
- Following cardioneuroablation, the patient experienced normalization of atrioventricular conduction.
- A nine-month follow-up revealed no recurrence of arrhythmias or adverse events.
- The procedure effectively resolved the high-degree atrioventricular block without the need for permanent pacing.
Conclusions:
- Cardioneuroablation represents a potentially effective and less invasive therapeutic option for young patients with high-degree atrioventricular block.
- This case highlights the feasibility of cardioneuroablation in a specific patient profile, including those with sickle cell trait.
- Further research and larger studies are warranted to establish the long-term safety and efficacy of cardioneuroablation in this population.
Abstract:
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.
