Reconstruction of the aortic root in patients with aortic root aneurysm and small aortic annulus is an intricate surgical procedure. Here, we describe our technique performed in 2 patients, that involved aortic root enlargement with grafting in conjunction with annular implantation of the composite graft with a prosthetic mechanical valve, which allowed us to avoid incompatibility. This novel method offers an alternative combined surgical approach for patients with small aortic annulus and aortic root aneurysm that preserves the structure of the valved conduit at the level of the aortic annulus.
