Cryoablation of AVNRT in children and adolescents: Early intervention leads to a better outcome

Research output: Contribution to journalArticlepeer-review


Cryoablation of AVNRT in Children and Adolescents Introduction Currently, transcatheter cryoablation is a well-established technique for the treatment of atrioventricular nodal reentry tachycardia (AVNRT) in children. In the past decade, many studies have focused on identifying factors that may affect acute and long-term outcome, but none has been shown to be strongly predictive of treatment success. The aim of our study was to determine whether patient age and cryoablation method correlate with acute and long-term success. Methods and Results We retrospectively reviewed 202 consecutive patients (98 male, mean age 11.5 years; range: 4-20 years) who underwent cryoablation for AVNRT at our institution from October 2002 to August 2012. Patients were divided into 2 groups according to age: group A
