Electrode sizing may guide preclinical RF ablation modeling; leaves open translation to human lesion prediction and device selection.
Does electrode radius predict lesion radius during radiofrequency energy heating in a canine right ventricular model?
The study validates a thermodynamic model showing that RF-induced lesion radius is directly proportional to electrode radius when interface temperature is held constant.
Haines et al. (1990) studied this question.
