Does systematic cryomapping and cryoablation effectively treat typical slow-fast AVNRT?
Cryomapping and cryoablation provide high acute and long-term success rates for treating typical slow-fast AVNRT with reasonable procedure times.
Jensen-Urstad et al. (2006) conducted an observational in Atrioventricular nodal reentry tachycardias (AVNRT) (n=75). Cryomapping and cryoablation was evaluated on Acute success rate. Cryoablation for typical slow-fast AVNRT achieved an acute success rate of 99% and a total success rate of 93% over a mean follow-up of 338 days.
