Objective:To explore the validity and safety of radiofrequeney catheter ablation of complex cardiac arrhythmias guided by a three-dimensional mapping system. Methods.. A cohort of 98 consecutive inpatients were registered from February 2006 to September 2008, of which 68 cases were male and 30 cases were female, with an average age of (50.2 ± 19. 7) years ranging from 9 to 88 years of age. These patients suffered from various arrhythmias including paroxysmal atrial fibrillation (50 cases), persistent or permanent atrial fibrillation (6 cases), atrial flutter (9 cases), atrial tachy-cardia (9 cases), ventricular tachycardia or frequent episode ventricular premature beat (24 cases). A total of 72 cases underwent radiofrequency catheter ablation of arrhythmias guided by an En-Site3000/NavX or Array mapping system, and 26 cases guided by a CARTO mapping system. Re-suits:Successful ablation of arrhythmias was performed for the first operation on 84 eases(85.71%),including 50 cases with atrial fibrillation,7 cases with atrial flutter, 7 cases with atrial tachycardia, and 20 cases with ventricular tachyeardia or premature ventricular beat. Success was made for the second operation on 7 patients, with a total success rate of 92.86%, including 3 cases with atrial fi-brillation, 1 case with recurred atrial flutter, 1 case with recurrent atrial tachycardia, and 2 caseswith ventricular tachycardia or premature ventricular beat. Complications occurred after operation in 6 cases, including cardiac tamponade in 4 cases, embolization in the remote left anterior descending coronary artery in 1 case, and pulmonary embolism in 1 case. Conclusion: Three-dimensional map-ping system can more clearly reveal the mechanisms of arrhythmias, and more efficiently guide the radiofrequency catheter ablation of complex arrhythmias, which contributes to improving the success rate of ablation and increasing the safety of catheter surgery.
