Abstract :
Radiofrequency catheter ablation can cure cases of atrial fibrillation. Multielectrode ablation catheters that can create long and contiguous lesions may benefit the physician by both increasing the predictability of lesion profiles and by reducing procedure time. This study presents an analysis of thermal profiles in tissue under a steerable 8F catheter capable of creating contiguous lesions. The catheter carried three 3-mm electrodes spaced 3.4 mm apart
