In vivo tissue temperatures during 90W/4se c-very high power-short-duration (vHPSD) ablation versus ablation index-guided 50W-HPSD ablation: A porcine study.

Actual tissue temperatures reached with 90W/4sec-vHPSD ablation appear similar to those with AI-guided 50W-HPSD ablation, with the distance between the catheter tip and target tissue being shorter for the former. Although both ablation settings may create transmural lesions in thin atrial tissues, any resulting esophageal thermal lesions appear shallower with 90W/4sec-vHPSD ablation.
