The PAINESD score predicts the risk of periprocedural acute hemodynamic decompensation (AHD) and postprocedural mortality in patients undergoing catheter ablation (CA) of scar-related ventricular tachycardia (VT). The role of prophylactic placement of percutaneous left ventricular assist devices (pLVADs) in high-risk patients is unknown. ⋯ Prophylactic pLVAD placement in high-risk patients undergoing CA of scar-related VT is associated with a reduced risk of AHD and death/transplant during follow-up without affecting VT-free survival.
