Abstract
After replacement of a bicuspid aortic valve with a Freestyle stentless xenograft, right coronary leaflet dysfunction and an elevated pressure gradient developed. Attempts to match the right and left ostia of the prosthesis, which were located at an angle of less than 120 degrees, to the native right and left ostia, which were located at 180 degrees, may have resulted in the leaflet distension. This is a suggestive finding about its implantation technique.
