During long- term follow-up, no abnormalities were found within the aortic root.

Background: Marfan's syndrome is characterized by progressive dilatation of the aortic root.

Significant echocardiographic abnormalities included aortic valve thickening, regurgitation and aortic root dilation.

Twelve patients had a concomitant aortic root aneurysm requiring surgical treatment.

Half the patients with pure aortic regurgitation showed aortic root dilatation.

However, little information is available on the relation between diabetes and aortic root diameter.

Results: Thirty-one percent of the patients had undergone previous procedures of the aortic root.

After elective aortic root replacement, a dilated distal aorta is more common than before.

Meticulous follow-up of the aortic root after repair, tetralogy of Fallot are thus recommended.

During daytime only Marfan patients with aortic root surgery showed increased pulse wave velocity.

Doppler values were evaluated for the Freestyle stentless porcine bioprostheses in the aortic root.

Isolated aortic root replacement could be performed at acceptable operative risk for this technically-challenging procedure.

Unexpectedly, β-galactosidase-positive areas in Mef2c-Cre mice extended from the aortic root throughout the ascending aorta.

Subsequently, we retracted the left coronary artery aside and pulled the posterior aortic root upwards.

Interventions involving only the aortic root, aortic valve, descending aorta, or thoracoabdominal aorta were excluded.

Conclusions: Our results confirm the hypothesis of a protective role of DM on aortic root dilatation.
