Transient atrioventricular block shortly after uneventful cryoablation of atrioventricular nodal re-entrant tachycardias: report of two cases

Show Summary Details

Preview

We report two patients with atrioventricular (AV) nodal re-entrant tachycardias who developed transient AV block immediately after uneventful cryoablation of the slow pathway was completed. No tachycardia recurrences were observed after an asymptomatic follow-up of 12 months and 10 months, respectively. This is the first report of this unexpected, transient phenomenon. The exact mechanism(s) remain(s) unclear.
