Key result
Nd:YAG laser creates controlled subendocardial injuries in dogs with ~13% pulse-related arrhythmias but no sustained VT.
Why the study?
Does percutaneous Nd:YAG laser coagulation create controlled subendocardial injuries without major side effects in a canine model?
Does percutaneous Nd:YAG laser coagulation create controlled subendocardial injuries without major side effects in a canine model?
Percutaneous Nd:YAG laser coagulation can safely create controlled subendocardial lesions in a canine model, suggesting potential utility for ablation of arrhythmogenic tissue.
No takes yet. Share an insight, caveat, or question.
Supports controlled lesions without sustained VT in dogs; leaves open human translation for arrhythmia ablation.
Wéber et al. (1989) studied Normal canine ventricle (n=8). Percutaneous Nd:YAG Laser Coagulation was evaluated on Ventricular arrhythmias during laser pulses. Percutaneous Nd:YAG laser coagulation in dogs created controlled subendocardial injuries with ventricular arrhythmias during 12.5% of pulses, but no sustained ventricular tachycardia up to 4 months.
