Abstract:
Objective To evaluate the feasibility of catheter ablation for atrial fibrillation (AF) guided by 3 dimensional (3D) mapping combined with pulmonary vein (PV) circumferential mapping Methods 14 consecutive patients (M/F=10/4, age 52 4?12 8 y o, left atrium diameter 46 7?5 4 mm) with drug refractory paroxysmal ( n =10), permanent ( n =3) and persistent ( n =1) AF were included in this study Left atrial modification guided by 3D mapping system were performed first,and then, all PVs were isolated by circumferential mapping guided segmental ablation The endpoint of ablation included: (1) all left artial ablation lines finished; (2) all PVs were isolated and (3) non inducibility of AF was observed Results (1) Ten (71 4%) patients with paroxysmal AF reached the endpoint of the ablation completely (2) Total procedure and fluoroscopy time periods were 292?49 min and 54?9 min, respectively (3) After a mean follow up of 5 2?5 7(1-23)weeks, 7 (50%) patients with paroxysmal AF were free of AF and 3 (21 4%) patients with paroxysmal AF had significant improvement (4) No complications occurred during the procedure and the follow up period Conclusion Catheter ablation for AF guided by 3D mapping combined with PV circumferential mapping is feasible, safe and effective for patients with paroxysmal AF and left atrial enlargement
