Review
Key result
A strategy of local abnormal ventricular activity (LAVA) mapping and elimination is feasible in about 70% of patients with scar-related VT and is associated with better outcomes than LAVA persistence.

May not yet alter scar-related VT ablation practice; leaves open need for randomized confirmation of LAVA elimination benefit.
Does substrate mapping and ablation aiming at local abnormal ventricular activity (LAVA) elimination improve outcomes in patients with scar-related ventricular tachycardia?
Complete elimination of local abnormal ventricular activity (LAVA) during VT ablation is feasible and associated with improved outcomes compared to LAVA persistence.
Sacher et al. (2014) conducted a review in Scar-related ventricular tachycardia. Local abnormal ventricular activity (LAVA) mapping and elimination vs. LAVA persistence was evaluated on Clinical outcome. A strategy of local abnormal ventricular activity (LAVA) mapping and elimination is feasible in about 70% of patients with scar-related VT and is associated with better outcomes than LAVA persistence.
