Preliminary experience with high-density electroanatomical mapping for ablation of atrial fibrillation - Comparison of mini-basket and novel open irrigated magnetic ablation catheter in consecutive patients

The high-density mapping system can successfully be used with both mini-basket catheters and ablation catheters employed for electro-anatomic reconstruction of the left atrium. While mapping is faster and point density higher with the mini-basket, procedure and fluoroscopy times are longer. The clinical significance of those findings needs to be investigated in future and larger studies.
