TCT 2013: Electrode irrigation alters RF ablation treatment zone geometry and preserves medial and adventitial tissue while maintaining injury to renal nerves

Keating J, Markham M, Stanley J, Tzafriri AR, Wong G, Spognardi AM, Fuimaono K, Grunewald D, O’Fallon P, Edelman ER. ‘Electrode irrigation alters RF ablation treatment zone geometry and preserves medial and adventitial tissue while maintaining injury to renal nerves.’

Podium presentation at: Transcatheter Cardiovascular Therapeutics (TCT); 2013 Oct 28-Nov 1; Washington, DC.

Summary: We quantitatively compared lesion geometry and artery and nerve injury with and without irrigation during RF ablation to enable optimization of catheter design and understanding of temperature gradients.
