Why the study?
Does transcatheter application of Nd:YAG laser energy produce controllable and reproducible myocardial lesions in normal and scarred ventricular myocardium in dogs?
Does transcatheter application of Nd:YAG laser energy produce controllable and reproducible myocardial lesions in normal and scarred ventricular myocardium in dogs?
Nd:YAG laser pulses produce homogeneous, reproducible coagulation necrosis lesions in both normal and scarred canine myocardium without complications, suggesting potential as an alternative energy source for ventricular arrhythmia ablation.
No takes yet. Share an insight, caveat, or question.
Optimal laser parameters create consistent lesions through scar in dogs; leaves open translation to human VT ablation.
Weber et al. (1998) studied this question.
