ABSTRACT
Objective:
To summarize our initial experience on three-dimensional electroanatomic mapping with Carto-Merge, so as to provide evidence for guiding catheter ablation of atrial fibrillation (AF).Methods:
Fifteen patients with paroxysmal/persistent AF (13 paroxysmal and 2 persistent), who were to receive catheter ablation, were analyzed by CARTO-MERGE, which combines computed tomography (CT) angiography, picture merging, guiding ablation, etc.Results:
There were 103±13 mapping points before ablation, with 66±15 in the left ablation circle and 58±20 in the right. The distance between points and surface was (1.8 ± 0.2) mm in the merged images. Operation time was (305 ± 45) min and the X-ray exposure time was (52 ± 18) min. Isolation of pulmonary veins potential was achieved in all patients and there was no complication during the operation.Conclusion:
Three-dimensional CT images is very close to the the real anatomy of left atrium and pulmonary veins. Carto-merge technique can overcome some shortcomings of Carto electroanatomic mapping pictures, which can improve the successful rate of operation and reduce complication.
