Liner Ablation Using Contact-force in Atrial Fibrillation — LIBCAAF  

Persistent Atrial Fibrillation Clinical Trial

Official title:
Left Atrial Liner Block Using Contact-force Catheter in Ablation for Atrial Fibrillation

Clinical Trial Summary

Linear ablation is frequently used in the procedure for persistent atrial fibrillation. However, it has a limitation because of technical difficulty. Incomplete block is common and an important cause of atrial tachycardia.

The association between contact force values and successful linear block has not been revealed yet. We aim to the effectiveness and safety of linear ablation by using CF sensing catheter.

Clinical Trial Description

Catheter ablation is currently accepted as a treatment option for symptomatic atrial fibrillation. Linear ablation is frequently used in the procedure for persistent atrial fibrillation. Multiple studies have shown benefit of linear ablation. However, it has a limitation because of technical difficulty. Incomplete block is common and an important cause of atrial tachycardia.

Contact-force (CF) monitoring during procedure has recently been available. This technology appears to significantly decrease procedure time and short term reconnection incidence in pulmonary vein (PV) isolation. It also helped to resolve the cause of PV reconnection. Some reports demonstrated that the association between reconnection and lower CF value.

Linear ablation has more variation to interrupt block and reconnection was more often than PV isolation. The association between CF values and successful linear block has not been revealed yet. In addition, the investigators aim to the effectiveness and safety of linear ablation by using CF sensing catheter. ;
