(A) Relationship between the balloon/annulus ratio and degree of aortic insufficiency (AI) at late follow-up. Note that there is no correlation with an r value of 0.36. (B) Relationship between the degree of aortic insufficiency (AI) immediately following balloon aortic valvuloplasty with AI at late follow-up. Note that there is a significant correlation with an r value of 0.71.
