BACKGROUND Many cardiovascular diseases, such as aortic dissection, frequently occur on the aortic arch and fluid-structure interactions play an important role in the cardiovascular system. Mechanical stress is crucial in the functioning of the cardiovascular system; therefore, stress analysis is a useful tool for understanding vascular pathophysiology. The present study is concerned with the s...

t rue saccular aneurysm is exceptional in coarctation of aorta in children. a 6-year-old girl with headache and systemic arterial hypertension referred to our center for cardiovascular evaluation. physical examination revealed high blood pressure and weak lower extremity pulses. two-dimensional and doppler echocardiography and angiography demonstrated a saccular aneurysm of the descending aorta...

Aims: To examine how left atrioventricular plane displacement (AVPD), a widely used measure of left ventricular (LV) function, is related to presence and degree of aortic stenosis. Methods and results: Cardiac dimensions, LV filling, left AVPD, LV ejection fraction (LVEF), and valve function were assessed by echocardiography/Doppler in 182 patients with various cardiac diseases (mean (SD) age 6...

Crocus sativus L. (saffron) is a widely used food additive for its color and taste. The hypotensive effects of saffron have been shown in previous studies. The aim of this study was to evaluate the mechanism of vasodilatory effects induced by saffron on isolated rat aorta.To study the vasodilatory effects of saffron aqueous extract (0.5, 1 and 2 mg/mL), isolated rat thoracic aorta rings were co...

  Introduction: Aortic valve sclerosisis considered as a manifestation of coronary atherosclerosis. Recent studies demonstrated an association between aortic valve sclerosis and obstructive coronary artery disease. The purpose of this study was to evaluatethe correlation betweenaortic valve sclerosis andobstructive coronary artery disease and the extent of coronary artery disease in patients ho...

PURPOSE Conventional surgical therapy of aortic arch aneurysms consists of aortic arch replacement requiring cardiopulmonary bypass and deep hypothermic circulatory arrest. This method is associated with significant morbidity and mortality, mainly due to neurologic complications and the sequelae of deep hypothermic circulatory arrest. Thus, it makes sense to work on developing less invasive sur...

background: the evaluation of prosthetic valves is very difficult with two-dimensional transthoracic echocardiography alone. doppler and color flow imaging as well as transesophageal echocardiography are more reliable to detect prosthetic valve dysfunction. however, doppler study sometimes tends to be misleading due to the load-depending characteristics of peak and mean pressure gradients. the ...

Traditionally, cardiac and vascular surgeons have been treating diseases of the aorta as individual specialists. Neither nor ever considered a whole, which can be diseased throughout its length at same time requiring more thoughtful different approach. Aortic dissection aneurysmal disease may well benefit from multidisciplinary In context this review, we discuss examples joint operating between...

Aortic diseases are highly evolutive pathological entities that may often have an acute clinical presentation. The estimated 5-year risk of rupture of a thoracic aortic aneurysm with a diameter between 4 and 5.9 cm is 16%, but it rises to 31% for aneurysms of > or = 6 cm. Endovascular treatment is an emerging alternative option to surgery with low invasiveness, which allows to treat even high s...
