Abstract:
Objective To evaluate the safety and feasibility of reconstruction technique of atrial septum puncture trajectory with the help of three - dimensional mapping system in performing radiofrequency catheter ablation for atrial fibrillation. Methods Sixty- eight consecutive patients with atrial fibrillation received two times of atrial septum puncture under fluoroscopic guidance to perform radiofrequency catheter ablation. Carto 3, a three - dimensional mapping system, was employed to construct the real time left atrium and pulmonary vein anatomy by using a rapid anatomical mapping (FAM) model. Then, FAM model was used to construct the trajectory, along which the ablation catheter passed from left atrium through the long sheath to the right atrium and finally into the inferior vena cava. The safety and the feasibility of this catheter trajectory, which could allow the catheter repeatedly enter the left atrium, were evaluated. Results By using 3D-reconstruction technique of atrial septum puncture trajectory, the ablation catheter could repeatedly enter the left atrium at right anterior oblique position as well as at left anterior oblique position under zero X-ray fluoroscopy. The average time spent for the procedure was (12. 18±2. 28) seconds. No any complication occurred. Conclusion The reconstruction technique of atrial septum puncture trajectory with the help of three-dimensional mapping system is simple and feasible, the ablation catheter can repeatedly enter the left atrium, the X-ray exposure time spent for catheter ablation of atrial fibrillation can be greatly reduced.
