Figure 2: (a) Cracking the valve ring of the surgically implanted bioprosthesis using a high pressure balloon. At 20 atmospheres, a small residual waist can be seen on the balloon. (b) at 22 atmospheres inflation pressure, the waist on the balloon disappears, accompanied by cracking of the valve at the 6 0'clock and 12 0'clock positions of the ring
