Coronary orifice rotation for symmetric bicuspidization of a paediatric unicuspid aortic valve.

Bicuspidization is a valid option for unicuspid aortic valve repair, in which creating symmetrical commissural orientation is essential for improved outcomes. However, the right coronary orifice often interferes with symmetrical attachment of the neocommissure. In a paediatric patient without aortic root dilation, we rotated the right coronary orifice clockwise by cutting out a triangular piece of the non-coronary sinus wall and augmenting it between the left and right coronary sinuses. A neocommissure with patching was sewn to the left side of the right coronary orifice, and the symmetrical bicuspidized configuration was adjusted in a standardized fashion according to the cusp effective height measurement.
