Key result
A 13-year-old female developed incessant junctional ectopic tachycardia following radiofrequency catheter ablation for AVNRT, which resolved within 30 days without long-term antiarrhythmic drugs.
Why the study?
Post-ablation junctional ectopic tachycardia is a very rarely reported complication following catheter ablation in the region of Koch's triangle.
Case Report (n=1)
JET is a rare but possible complication of AVNRT ablation in children that may be refractory to medical therapy but can resolve spontaneously over time.
Refractory post-ablation JET may resolve spontaneously in children; leaves open optimal acute management strategies.
Junctional ectopic tachycardia (JET) occurs postoperatively or after catheter ablation in the region of Koch's triangle. The post-ablation incidence of JET reported in the medical literature is very low. We report the case of a 13-year-old female patient who underwent catheter ablation of the slow pathway for atrioventricular node reentrant tachycardia and subsequently developed JET. An accelerated automatic ectopic focus was found in the atrioventricular junction area due to radiofrequency applications. Treatment with metoprolol, ivabradine, propafenone, and amiodarone was ineffective in stopping the arrhythmia. However, JET resolved within 30 days without other antiarrhythmic drugs.

Cismaru et al. (2023) conducted a case report in Atrioventricular node reentrant tachycardia (AVNRT) (n=1). Radiofrequency catheter ablation was evaluated on Development of junctional ectopic tachycardia (JET). A 13-year-old female developed incessant junctional ectopic tachycardia following radiofrequency catheter ablation for AVNRT, which resolved within 30 days without long-term antiarrhythmic drugs.
