Key result
Use of a new transverse ovoidal composite graft for aortic root replacement resulted in 0% incidence of pseudoaneurysms at the coronary anastomosis site over a mean follow-up of 41 months.
Why the study?
Does a new transverse ovoidal composite graft prevent surgical complications and pseudoaneurysms in patients undergoing ascending aorta and aortic valve replacement?

Does a new transverse ovoidal composite graft prevent surgical complications and pseudoaneurysms in patients undergoing ascending aorta and aortic valve replacement?
A novel transverse ovoidal composite graft for aortic root replacement appears safe and effectively prevents coronary anastomosis complications such as pseudoaneurysms over long-term follow-up.
This cohort experience with a novel aortovalvular prosthesis leaves open its role in aortic root replacement; prospective trials needed before adoption.
The problems encountered in coronary artery reattachment when the ascending aorta and aortic valve are replaced with a composite graft induced Gallucci and one of the authors to develop a new aortovalvular prosthesis in clinical practice. The unique transverse ovoidal shape of this graft is intended to conform to the natural aortic root and facilitate the coronary anastomoses and minimize bleeding. We present our 6-year experience with 56 patients operated upon with this prosthesis. In all patients we were able to connect the coronary arteries directly to the graft without complications including hemorrhage or distortion of the coronary ostia. The survivors were evaluated with chest X ray, two-dimensional echocardiography, and conventional or digital subtraction angiography to detect the presence of pseudoaneurysms at the site of the coronary anastomosis, reported by others that have used the composite graft technique. The notable absence of this complication in our patients at a mean follow-up of 41 months (range 3-71) documents that this ovoidal composite graft is a reliable tool in the treatment of aortic root pathology.

Rocco et al. (1992) conducted an observational in Aortic root pathology (n=56). New transverse ovoidal composite graft was evaluated on Pseudoaneurysms at the site of the coronary anastomosis. Use of a new transverse ovoidal composite graft for aortic root replacement resulted in 0% incidence of pseudoaneurysms at the coronary anastomosis site over a mean follow-up of 41 months.
