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...

Introduction: Atherosclerosis has been shown to be a systemic disease frequently involving multiple vascular beds . Atherosclerotic diseases occurring in carotid arteries and thoracic aorta have been demonstrated to be associated with transient ischemic attack (TIA) and stroke . Recently, Mani et al [5] reported that both carotid artery and thoracic aorta showed greater plaque burden in patient...

Aortic dissection occurs when the layers of the aorta separate as a result of extra luminal cavity of blood through an intimal tear. Dissection limited to the abdominal aorta is rare. Unfortunately, the appropriate management of dissecting aneurysm of abdominal aorta is not documented yet. A 43 years old man was admitted to Al-zahra hospital in Isfahan with sudden onset of periumbilical abdomin...

Bicuspid aortic valve is traditionally considered an innocuous congenital anomaly. Due to a better and widespread availability of non-invasive imaging techniques, it has come to the fore that 30% of these cases develop complications, viz., valve abnormality (aortic regurgitation and stenosis), and aneurysm of aortic root and ascending aorta. Sinus of Valsalva aneurysm is an uncommon complicatio...

The endothelial permeability of aorta (EPA) is influenced by atherosclerosis.  Whether the physiological difference in EPA is a sex-dependent phenomenon remains to be determined.  The objective of this study was to determine the EPA difference between male and female rabbits.  An experimental model was designed to obtain 4 groups of animals.  The ovariectomized rabbits were fed with normal (gro...

Objective(s):The aim of this study was to investigate the effects of nutritional saffron (Crocus sativus L.) stigma hydroalcoholic extract on blood pressure (BP) and histology of the aorta in normotensive and hypertensive rats. Materials and Methods:   Saffron (200 mg/kg/day) was given orally for 5 weeks to normotensive and hypertensive rats. Hypertension was induced by NG-nitro-L-arginine meth...

Background: Scimitar syndrome (SS) or congenital pulmonary venolobar syndrome is a rare anomaly, most commonly including partial pulmonary venous drainage into the inferior vena cava, right lung hypoplasia, dextroposition of the heart, and anomalous systemic arterial supply from aorta or one of its branches to the right lung. Case report: A 10-day-old female infant was referred to our hospital...

Thrombotic events are very unusual in neonatal period. This congenital anomaly may be caused by certain risk factors such as polycythemia, perinatal asphyxia, septicemia, maternal diabetes, dehydration, and low cardiac output, or it may occur upon catheterization of central lines. A 20-day-old neonate was referred to our ward with primary signs of hypertrophic cardiomyopathy (HCMP). Echocardiog...

This study focuses on the biaxial mechanical properties of planar aorta tissue at strain rates likely to be experienced during automotive crashes. It also examines the structural response of the whole aorta to longitudinal tension. Twenty-six tissue-level tests were conducted using twelve thoracic aortas harvested from human cadavers. Cruciate samples were excised from the ascending, peri-isthm...
