Aortic valve replacement with Y-incision/rectangular patch aortic annular enlargement

A small aortic root and annulus would need extensive aortic annular enlargement during valve replacement in adult patients to avoid patient-prosthesis mismatch. This report describes a technique that enlarges the aortic annulus by 4–5 valve sizes as well as a modification of the aortotomy with the roof technique to make the aortotomy closure easier and more hemostatic while enlarging the sinotubular junction and proximal ascending aorta effectively for future transcatheter valve-in-valve replacement.
