ABSTRACT
BACKGROUND:
Presently used pulmonary vein antrum location methods mainly performed by three-dimensional electroanatomy combined with X-ray image or CT image fusion.These methods conducted vein antrum location and ablation by anatomy instructions.It is still poorly understood whether the ablation hit the key part of atrial fibrillation.OBJECTIVE:
To explore the feasibility of catheter ablation guided by three-dimensional electroanatomic mapping system in conjunct with pulmonary vein antrum potential in patients with atrial fibrillation.DESIGN,TIME ANDSETTING:
The verification clinical study was performed at the Department of Cardiology of Jinan Fourth People's Hospital and Hebei People's Hospital from March 2007 to June 2009.PARTICIPANTS:
Fifty-one patients with drugs refractory,paroxysmal atrial fibrillation were included.METHODS:
All patients underwent circumferential pulmonary vein antrum ablation guided by three-dimensional electroanatomic mapping system (CARTO) in conjunct with pulmonary vein antrum potential with the endpoint of electrical isolation.Relevant parameters and ablation success rate were observed.MAIN OUTCOMEMEASURES:
Procedure-related parameters,such as procedure duration,fluoroscopy duration,cumulative success rate and complication were observed.RESULTS:
Pulmonary veins were isolated in all 51 patients.The mean procedure duration,fluoroscopy time and radiofrequency ablation duration are respectively (207±36.7) minutes,(38.2±14.3) minutes,(56.4±15.7) minutes.After (17.5±3.8)-months follow-up,forty (78.4%) patients did not have recurrence of atrial fibrillation,atrial flutter or atrial tachycardia.No severe procedure-related complication had happened.CONCLUSION:
Pulmonary vein antrum potential can be used as a landmark to define pulmonary vein antrum,that combined with CARTO system to guide pulmonary vein antrum ablation is effective,safety and feasible for catheter ablation of atrial fibrillation.
