Table 1: Summary of findings. Of 183 patients, 90 received RF ablation with LET monitoring and 93 received RF ablation with esophageal cooling. In the pre-adoption cohort the average age was 69.6 years (SD ± 10.34), 45.6% (41 patients) reported chest pain, 66.7% (60 patients) had persistent AF, 68.9% (62 patients) received roof lines, and 66.7% (60 patients) received floor lines. In the post-adoption cohort the average age was 68.3 years (SD ± 10.28), 0% (0 patients) reported chest pain (p<0.0001), 75.2% (70 patients) had persistent AF (p=0.250), 84.5% (79 patients) received roof lines (p=0.013), and 80.6% (75 patients) received floor lines (p=0.043).
3.4 Outcomes
In the pre-adoption cohort, 41 of the 90 patients (45.6%) reported post-ablation chest pain requiring extension of treatment to 6 weeks(Figure 3) and in the post-adoption cohort, none of the 93 patients reported post-ablation chest pain (p<0.0001).
