background vascular ring is less than 1% of congenital heart disease. double aortic arch (daa) is the most common form of it.  its detecting is important because of the effects of pressure on the esophagus and trachea. case report in this study, three children suffering from double aortic arch with symptoms of dysphagia and recurrent aspiration, which in two cases had led to cardiac arrest, wer...

soon after successful results of balloon valvuloplasty in treatment of congenital pulmonary stenosis, use of this technique for relief of congenital aortic stenosis (as) was attempted in different parts of the world. with the purpose of assessment the value of valvuloplasty in comparison with surgical valvotomy in relief of congenital as, we retrospectively studied 115 patients with valvar as, ...

background: blood viscosity and aortic sclerosis (as) are strong predictors of cardiovascular events. the effects of blood viscosity on as have not been studied adequately. we aimed to investigate the potential connection between whole blood viscosity (wbv) and as. methods:   as was detected by transthoracic echocardiography. the estimation of wbv was carried out at both high shear rate (hsr) (...

a simple emergency risk prediction tool should be developed for clinicians to quickly identify the prognosis of patients with acute aortic dissection.we enrolled 280 patients with acute aortic dissection admitted to emergency department between may 2010 and february 2013. multivariate logistic regression analysis was performed to identify independent predictors of in-hospital death.the in-hospi...

conclusions considering the unique construct of the powerlink stents, this is thought to represent aneurysmal degeneration of the outer fabric material from the metal struts and may potentially pressurize the excluded sac with risk for rupture. case presentation a 65-year-old woman who had endovascular aortic repair (evar) of an abdominal aortic aneurysm with endologix powerlink system develope...

A seven-year-old girl with clinical diagnosis of aortic insufficiency underwent echocardiographic and hemodynamic evaluation and referred for surgery with the same diagnosis. However, at surgery, aorto-Ieft ventricular tunnel was found and repaired successfully. Review of echocardiogram and catheterization data revealed interesting findings to differentiate this rare entity from congenital...

Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...

the present investigation was undertaken to evaluate the effect of antihypertensive drugs on aortic atherogenesis in hypercholesterolemic rabbits. in enalapril and nifedipine treated rabbits aortic atherosclerotic plaque involvement was significantly decreased (p<0. oland p

introduction although a few patients will survive after penetrating cardiac injuries, some of them may have unnoticeable intracardiac injuries. the combination of aorto-right ventricular fistula with aortic valve injury is rare. case presentation a 19 year-old man referred with an aorto-right ventricular fistula accompanied with aortic regurgitation and delayed tamponade following a stab in the...
