Figure 4 Effect of Balloon Oversizing the Annulus in Bicuspid Aortic Valves

(A) Comparison of difference between balloon diameter and surgically measured annulus versus additional intraballoon pressure (AIBP) in mild (blue diamonds), moderate (red squares), and severely (yellow triangles) calcified bicuspid aortic valves. (B) Comparison of difference between balloon diameter and transesophageal echocardiogram (TEE)-measured annulus versus AIBP in mild, moderate, and severely calcified bicuspid aortic valves. *Leaflet avulsion.
