Long-term follow-up after cryoablation for adolescent atrioventricular nodal reentrant tachycardia: recurrence is not predictable

Abstract

Although cryoablation for the treatment for AVNRT in paediatric and adolescent patients is safe and associated with a high acute success rate, AVNRT recurrence occurs in 22% of patients during long-term follow-up without identifiable predictors for recurrence. A second cryoablation procedure leads to a success rate of 100% during long-term follow-up.
