NCT02019407

Brief Summary

Prospective Randomized Study on Clinical Effectiveness of Carvo-Tricuspid Isthmus (CTI) Block in Patients with Paroxysmal Atrial Fibrillation (PAF) will be performed. Study will be composed with two arms including 4 pulmonary vein isolation and pulmonary vein isolation with CTI block. After that all patients will be followed up by HRS(Heart Rhythm Society) 2010 expert consensus guideline.

Outcome Measures

Primary Outcomes (1)

  • Recurrence of Atrial fibrillation (AF free survival)

    clinical recurrence of AF after catheter ablation

    3 month after catheter ablation

Study Arms (2)

CTI group

EXPERIMENTAL

CTI(Cavo-Tricuspid Isthmus)

Procedure: PVI, CTI block

Non CTI group

PLACEBO COMPARATOR

Non CTI (Cavo-Tricuspid Isthmus)

Procedure: PVI

Interventions

* 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.

Also known as: radiofrequency catheter ablation (RFCA), Catheter ablation of cavo-tricuspid isthmus line for treatment of atrial flutter
CTI group
PVIPROCEDURE

PVI (pulmonary isolation)

Non CTI group
