title: Aortic valve-sparing operations: dealing with the coronary artery that is too close to the aortic annulus.
abstract: During aortic root surgery, one of the coronary ostia is sometimes found to lie too close to one of the commissures to allow its safe detachment as a button while still preserving the native aortic valve. In the past, this has prevented aortic valve-sparing root replacement in cases of aortic root aneurysm. We describe a technique pertaining to the reimplantation method of aortic valve-sparing root replacement to deal with such a displaced coronary artery.
