Extensive aortic prosthesis dilatation [PDF]

European Journal of Cardio-Thoracic Surgery, 2012
Figure 1: A CT scan 2 years (A) and 14 years (B) after the initial aortic repair. It shows the enlarged prosthesis diameter of 42 mm (black dotted arrows), which has remained stable over time. Compared with the original dimension, the cross-sectional area of the prosthesis increased by 96%, and the prosthesis wall tension by 40%.

Donor aortic root dilation [PDF]

Canadian Journal of Cardiology, 2009
A patient underwent heart transplantation for dilated cardiomyopathy 17 years previously. The donor was a 14-year-old girl with no known cardiovascular disease. In 2005, on routine imaging, the patient was found to have an ascending aortic aneurysm. The condition progressed over the next three years, leading to moderate aortic insufficiency and severe ...

Pravastatin Reduces Marfan Aortic Dilation [PDF]

Circulation, 2011
Background— The sequelae of aortic root dilation are the lethal consequences of Marfan syndrome. The root dilation is attributable to an imbalance between deposition of matrix elements and metalloproteinases in the aortic medial layer as a result of excessive transforming growth factor-beta signaling.

Dilated aortic root is related to a global aortic dilating diathesis [PDF]

Journal of Vascular Surgery, 2010
The purpose of this study was to analyze the association between the dilatation of the aortic root and the diameters of the rest of the aorta and to identify some related factors that could be used to identify patients at higher risk of presenting with an aortic aneurysm.In 71 consecutive patients with a dilated aortic root identified by transthoracic ...

Late follow-up of neo-aortic dimensions and coronary arteries in adult patients after the arterial switch operation

International Journal of Cardiology Congenital Heart Disease, 2023
Background: After the arterial switch operation (ASO) for transposition of the great arteries (TGA), neo-aortic dilatation and coronary arterial anomalies, especially an interarterial course and acute coronary artery take-off angle, are commonly found ...

Abnormal Flow Dynamics Result in Low Wall Shear Stress and High Oscillatory Shear Index in Abdominal Aortic Dilatation: Initial in vivo Assessment with 4D-flow MRI

Magnetic Resonance in Medical Sciences, 2020
Purpose: To characterize the non-laminar flow dynamics and resultant decreased wall shear stress (WSS) and high oscillatory shear index (OSI) of the infrarenal abdominal aortic dilatation, cardiac phase-resolved 3D phase-contrast MRI (4D-flow MRI) was ...

Prevalence and prognostic factors for aortic dilatation in giant cell arteritis - a longitudinal study.

Seminars in Arthritis & Rheumatism, 2020
OBJECTIVES Predictive data for the development of aortic dilatation (AD) in giant-cell arteritis (GCA) are controversial. The aim was to investigate by computed tomography (CT) the prevalence of AD in a consecutive cohort of GCA patients and controls ...

Prevalence and progression of aortic dilatation in adult patients with Turner syndrome: a cohort study.

European Journal of Endocrinology, 2020
Objective Turner syndrome (TS) is a rare disorder affecting 1/2500 female newborn. Aortic dilatation (AD) and aortic dissection represent a major concern in TS.
