Recreation of the geometric configuration of the functional bicuspid aortic root. (A) Asymmetric Sievers type I R/L BAV with dilatation of basal ring to 34 mm, prolapse of the fused cusp (*), normal non-coronary cusp (#) and aneurysm of the aortic root which has been excised. Arrow indicates raphe between right and left coronary cusp; (B) valve sparing root replacement by remodeling technique (*) with an additional reduction of basal ring diameter to 25 mm, prolapse correction of both cusps (arrow) and recreation of the symmetric configuration of bicuspid valve. Cross marks indicate the bottom of right coronary ostium.
