Relationship Between Ablation Lesion Size Estimated by Ablation Index and Different Ablation Settings—an Ex Vivo Porcine Heart Study
This study aimed to verify the reliability of ablation index (AI) for ablation lesion estimating with different settings for radiofrequency (RF) parameters: power, impedance, contact angles, irrigation rate, temperature of irrigation saline, and irrigation solution. RF ablations ( N = 66) were perf...
