Intervention
Electrophysiology study and modification of the slow pathway using cryoablation

Johnson et al. (2014) conducted a case report in Atypical atrioventricular nodal reentry tachycardia and polyvalvular dysplasia (n=1). Cryoablation modification of the slow pathway was evaluated on Successful modification of the slow pathway. Cryoablation successfully modified the slow pathway in a 10-year-old boy with polyvalvular dysplasia and atypical atrioventricular nodal reentrant tachycardia.
