Catheter ablation for treatment of tachyarrhythmia

ABSTRACT

Catheter ablation is one of the major treatment options for patients with arrhythmia. It has been widely used since radiofrequency energy was adopted as a power source. Technical progress has resulted in better outcomes, better efficiency, and safer procedures. However, mechanisms of some forms of arrhythmia such as atrial fibrillation have not been fully elucidated in order to obtain a more favorable success rate. Therefore, progress in the basic research field to understand the mechanisms and substrates of arrhythmia as well as technical progress is essential for overcoming current obstacles in this therapeutic method.
