Successful selective ablation of fast atrioventricular node pathway by cryothermal energy application.
This paper reports the experience of successful cryoablation of fast atrioventricular nodal pathway in a patient with recurrent atrioventricular nodal reentrant tachycardia after previous unsuccessful attempts of slow pathway ablation. Slow formation of a permanent lesion by cryothermal energy application allowed precise modulation of atrioventricular nodal conduction until the endpoints of complete fast pathway ablation were met with long-term cure of the arrhythmia.
