[Radiofrequency ablation of heart arrhythmias. Results in the first 150 patients treated at the Arrhythmia center in Oslo].
The authors review the first 150 patients with cardiac arrhythmias who were treated with radio-frequency ablation at a Norwegian arrhythmia centre. The clinical success rate (either electrophysiological cure or a dramatic reduction in the severity and frequency of the attacks) was 97%. 11 patients were treated for two or more arrhythmias. In 27 patients two, occasionally three, sessions were required to obtain a satisfactory clinical result. Repeat ablation is scheduled for three cases where the treatment was unsuccessful. Among 190 ablations, 13 complications occurred, none of which resulted in permanent sequelae. The time spent on each procedure, and particularly the long time spent on fluoroscopy during the earlier procedures, demonstrates the existence of a learning curve for ablation. This lends support to the authorities' restriction of treatment of arrhythmias by ablation to only two laboratories in a population of four million.
