Abstract:
Thermal-based ablation for the treatment of arrhythmias is known to cause issues (e.g. heat loss due to blood perfusion, mechanical damage of the tissue from excessive heat, etc.) that hamper the success of the treatment. A novel technique termed "electroporation" is a process that leads to pore formation in cell membranes. These pores may cause cellular death without inducing negative thermal effects. We successfully developed a system, tools, and methodology to operate this new ablation technique. Preliminary in vivo acute animal studies (ovine) suggest distinct lesion morphology. High transmurality success rates also suggest the possibility of applying this new ablation modality to cardiac ablation. A long term study confirming lesion durability is necessary to warrant the successful adoption of this technique.
