OBJECTIVES The purpose of this study was to describe the phenotypic characteristics of an inherited myxomatous valvular dystrophy mapped to Xq28. BACKGROUND Myxomatous valve dystrophies are a frequent cause of valvular diseases, the most common being idiopathic mitral valve prolapse. They form a group of heterogeneous diseases difficult to subclassify. The first mapping of the gene for a myxo...
OBJECTIVES Cardiovascular diseases, such as atherosclerosis and aneurysm, are closely associated with haemodynamic factors that are governed by luminal geometry. The present work aimed to study the effect of geometrical variation of aging aortas on haemodynamics. METHODS Six aged subjects with intricate geometrical features, such as bulging or twisted supra-aortic arteries, sharply curved arc...
BACKGROUND ACTA2 mutations are the major cause of familial thoracic aortic aneurysms and dissections. We sought to characterize these aortic diseases in a large case series of individuals with ACTA2 mutations. METHODS AND RESULTS Aortic disease, management, and outcome associated with the first aortic event (aortic dissection or aneurysm repair) were abstracted from the medical records of 277...
CT revealed also a right aortic arch, classified as an aortic anomaly of type III-A: A mirror image branching of the normal left aortic arch, according to Edward’s classification (Panel B). Type IIIB is the most frequent, followed by Type IIIA. The classification of aortic anomalies by Edward’s et al. is based on their theoretical concept of the development of the aortic arch. Right aortic arch...
Introduction: Patients with primary acute aortic dissection are at higher risk of complications, including increasing aortic aneurysm diameter, aortic rupture, aortic pseudo aneurysm, and recurrent aortic dissection. Case presentation We presented the case of a recurrent pseudo aneurysm and rupture of the aorta in the distal a...
Background Recently, the LDL/HDL-cholesterol ratio has become recognized as a stronger risk predictor of cardiovascular diseases than each lipid parameter. However, the association between LDL/HDL-cholesterol ratio and aortic atherosclerosis has not been elucidated yet. Using MRI, we investigated the associations between thoracic and abdominal aortic atherosclerosis and LDL/HDL-cholesterol rati...
An app in the area of Aortic Diseases (ascending aortic aneurysm) was developed. This article offers a brief introduction about the information received and transmitted in the app and the process through which it was developed as well as its contents.
Obstructive sleep apnea (OSA) is a causal pathogenetic factor of many cardiovascular diseases, however, its role in aortic diseases remains unknown. Therefore, this study was performed to explore the potential effects and pathophysiological mechanisms of chronic OSA on aortic remodeling in a canine model. After chronic OSA, the morphological changes of ascending aorta were characterized by thin...
PURPOSE To analyze aortic elastic properties (AEP) characteristics, dissection and elastic data of ascending aorta (AA) in the population with a high risk of aortic diseases. METHODS Forty five patients with artery diseases undergoing aortic digital subtraction angiography (DSA) were enrolled in this study. The maximal, minimal diameter and changes in diameter of ascending and descending aort...
