Key result
Radiofrequency ablation requires heating myocardial tissue to ~55°C while staying below 80°C to prevent complications.
Why the study?
The effects of convective cooling on lesion formation during radiofrequency ablation and optimal temperature thresholds to avoid complications are not fully characterized.
Radiofrequency (RF) ablation uses alternating electrical current to generate heat at the catheter-tissue interface. The goal is the produce irreversible myocardial tissue injury by raising the tissue temperature above the lethal threshold, variably estimated at approximately 53.6±3.20°C to 60.6 (IQR 59.7-62.4) °C(1,2). Ideally, the tissue temperature should not exceed boiling point and the tissue surface temperature should be kept less than 80°C to avoid complications such as steam pop and coagulum or char formation, respectively.

Pierre Cheng Qian (2023) conducted a review in Radiofrequency ablation. Radiofrequency ablation was evaluated. Radiofrequency ablation requires raising myocardial tissue temperature above a lethal threshold (approximately 54-61°C) while keeping surface temperature below 80°C to avoid complications.
