Key Points Post TAVR PVL closure with low profile vascular plugs is feasible, even for the relatively longer frame of the CoreValve device. Device closure for PVL may be successful even after post‐dilatation and valve‐in‐valve have failed. The low profile of the AVP4, which can pass through 4‐5F diagnostic catheters, makes this approach practical.
