Brain & Heart Balloon valvuloplasty for aortic stenosis

Figure 8. Pressure tracings from the left ventricle and aorta were recorded simultaneously (A) before balloon aortic valvuloplasty (BAV), indicating a
significant aortic valve pressure gradient. Following BAV (B), the aortic valve pressure gradient was abolished. The fall in diastolic pressure in the aorta
following BAV is probably due to the development of aortic insufficiency. Reproduced from Agu and Rao. 12

the pressure gradients are lower (p < 0.001) than those before BAV.
