No results posted yet for this study

Summary

The purpose of this study is to evaluate the efficacy of additional ablation targeting complex fractionated atrial electrogram area within low voltage zone identified by high resolution mapping in patients with persistent atrial fibrillation.

Conditions

Interventions

PROCEDURE

pulmonary vein isolation

pulmonary vein isolation is conducted on the junction between the left atrium and pulmonary vein

PROCEDURE

Low-Voltage & CFAE guided ablation

In CFAE guided ablation,. Within low voltage zone, CFAE areas defined by shortest SCI and high ICL are identified.-Areas with the shortest SCI and high ICL within low voltage areas should be targeted first, followed by longer SCI regions (up to 120ms). Radiofrequency energy is delivered at target sites for 30-60 sec until the local electrogram is completely eliminated.
