Modification of Y-incision technique with Valsalva graft to enlarge subvalvular space
Abstract
The Y-incision aortic annular enlargement technique, introduced by Dr Bo Yang in 2021, has been shown to effectively enlarge small aortic annuli, allowing for implantation of larger prosthetic valves while preserving structural integrity.1 However, when implanting a larger prosthetic valve after annular enlargement, it is important to ensure that adequate space is provided below the valve. If the prosthetic valve is oversized for a restricted subvalvular space, it may not function optimally, potentially impairing hemodynamics and reducing the durability of the valve.
