Does ultra high-density 3-D mapping using a 64-electrode mini-basket catheter enable feasible substrate characterization and guide catheter ablation in patients with scar-related ventricular tachycardia?
Ultra high-density 3-D mapping using a 64-electrode mini-basket catheter is feasible for substrate characterization and guiding ablation in patients with scar-related VT, yielding a 90% freedom from VT recurrence at 4 months.
Nührich et al. (2017) conducted an observational in Scar-related ventricular tachycardia (n=22). Ultra high-density 3-D mapping and catheter ablation using a 64-electrode mini-basket catheter was evaluated on Freedom from VT recurrence. Ultra high-density 3-D mapping and catheter ablation in patients with scar-related ventricular tachycardia was feasible, with 90% of patients remaining free from VT recurrence at 4 months.
