Valve‐in‐valve transcatheter aortic valve replacement (VIV TAVR) has emerged as a preferable option for high surgical risk patients requiring redo aortic valve replacement. However, VIV TAVR may restrict flow, especially in small native aortic valves. To remedy this, bioprosthetic valve fracture has been utilized to increase the effective orifice area and improve hemodynamics. We present three cases in which bioprosthetic valve fracture was used to increase hemodynamic flow in VIV TAVR procedures.
