Patients 1, 3, and 4 were listed for transplant with plans for staged valvuloplasty less than 48 hours prior to OLT (Figure 1).
Transthoracic echocardiography before and after valvuloplasty shows a calcified, stenotic aortic valve with AVA of 0.8 cm2 by planimetry and continuity equation (VTI). Postvalvuloplasty there is demonstrated improvement in aortic valve gradients as well as AVA.

Each underwent successful BAV with invasive and echo documentation of improvements in valvular gradients and AVA. (Figure 2) Each patient then underwent OLT within 38 hours of valvuloplasty.
