Asset Details

  • Description:
  • The mean lesion cross‐sectional area (mm2± SD) at each millimeter depth from the endocardium is shown for all lesions. Control (standard 4‐mm tip) ablation lesions reached maximal cross‐sectional area at 2‐mm depth from the endocardium and rapidly tapered. Irrigated‐tip ablation lesions had a significantly larger volume and larger cross‐sectional area from 1 to 7 mm depth to the endocardium (*P < 0.05). Low‐power infusion‐needle ablation lesions had a similar profile to 4‐mm‐tip lesions at shallow depths, but were significantly deeper than control lesions. High‐power infusion‐needle ablation lesions had significantly greater cross‐sectional area than 4‐mm‐tip control lesions at all depths beyond the endocardium (†P < 0.05) and were significantly deeper. High‐power infusion‐needle ablation lesions also had significantly greater cross‐sectional area than irrigated‐tip lesions at all depths beyond 4 mm from the endocardium (P < 0.05). The mean volume of high‐power infusion‐needle ablation lesions (area under the curve) was significantly larger than control lesions.
