How do varying parameters such as atrial thickness, electrode insertion depth, and epicardial fat affect lesion characteristics during epicardial atrial radiofrequency ablation in a finite element model?
Computational modeling highlights the critical influence of atrial thickness and epicardial fat on achieving transmural lesions during epicardial radiofrequency ablation.
Berjano et al. (2004) studied Atrial fibrillation. Epicardial radiofrequency ablation was evaluated on Temperature distribution and lesion characteristics. Finite element modeling of epicardial radiofrequency ablation showed that convective cooling is negligible for atria >3 mm thick, and epicardial fat significantly decreases lesion dimensions.
