Does intraoperative Neodymium:YAG laser photocoagulation successfully ablate drug-resistant ventricular tachycardia?
Intraoperative Nd:YAG laser photocoagulation is an effective technique for ablating drug-resistant ventricular tachycardia, particularly in patients with prior myocardial infarction.
Svenson et al. (1987) conducted an observational in drug-resistant ventricular tachycardia (n=17). Neodymium:YAG laser photocoagulation was evaluated on successful ablation of ventricular tachycardia morphologies. Intraoperative Neodymium:YAG laser photocoagulation successfully abated 52 of 55 ventricular tachycardia morphologies, achieving a 100% surgical cure rate in long-term survivors with prior MI.
