* PVI (pulmonary isolation) * Catheter ablation of cavo-tricuspid isthmus line for treatment of atrial fibrillation Catheter is inserted into inferior venacava (IVC) and right atrium (RA) via femoral vein. And the procedure is to block bidirectionally between inferior venacava (IVC) and the annulus of tricuspid valve (TV) by using electrical energy of catheter tip.
