Limb ischemia is a dreaded complication of large-bore access during prolonged Impella support. We report a novel technique to modify 14F Impella sheath by creating two perfusion holes in the dorsal sheath surface to enable distal limb perfusion via dead space surrounding 9F Impella catheter in flow-occlusive iliofemoral arteries.
