Research output: Contribution to journalConference articlepeer-review


The biophysics of saline irrigated ablation was examined. For this purpose, irrigated and non-irrigated ablation was performed in vitro utilizing a whole blood superfused apparatus. Electrode, electromvocardial interface, and intramvocardial temperatures were assessed, as were ablation circuit impedance, total delivered energy, lesion and electrode morphology. It was found that saline irrigated ablation is associated with greater ablation energy deposition and larger lesion dimensions than non-irrigated modes.
