Why the study?
Does catheter ablation with a Nd-YAG laser hot tip catheter increase lesion size in an isolated perfused pig heart model?
Does catheter ablation with a Nd-YAG laser hot tip catheter increase lesion size in an isolated perfused pig heart model?
Nd-YAG laser hot tip catheter ablation is feasible in vitro but high temperatures cause tissue desiccation that limits lesion size and increases perforation risk.
No takes yet. Share an insight, caveat, or question.
High temperatures risk perforation while limiting lesion size via desiccation; hypothesis-generating for laser parameter optimization before in vivo testing.
David E. Haines (1992) studied this question.
