Aortic aneurysm

Vasovagal Syncope, Adult Syncope, which is commonly known as fainting or passing out, is a temporary loss of consciousness. It occurs when the blood flow to the brain is reduced. Vasovagal syncope, which is also called neurocardiogenic syncope, is a fainting spell that happens when blood flow to the brain is reduced because of a sudden drop in heart rate and blood pressure. Vasovagal syncope is usually harmless. However, you can get injured if you fall during a fainting spell. CAUSES This…

Walt Whitman’s poem, “When I Heard the Learn’d Astronomer,” which is written based on prior experience, presents two different views based around focusing on how people understand certain material. These perspectives are exhibited through a class lecture on astronomy. Whitman wrote this poem based on prior experience. The poem begins with the speaker sitting through an astronomy lecture taught by an astronomer. The lesson focuses on scientific facts and mathematical figures. The information is…

Prosthetic aortic valve endocarditis without evidence of vegetation Introduction The modified Duke criteria for the diagnosis of infective endocarditis (IE) include three major and five minor criteria. One of the major criteria is evidence of structural findings on echocardiography such as an oscillating intracardiac mass, abscess or partial dehiscence of a prosthetic valve (1-2). Less common echocardiographic findings of IE include pseudoaneurysm, fistula, or valve perforation. The American…

average, two out of every one thousand people have this medical condition (“Aortic Valve Stenosis”). What is this potentially deadly disorder and who does it affect? This disorder is called Aortic Valve Stenosis and it can affect anyone. Aortic Valve Stenosis, also known as AVS, happens when the aortic valve narrows. The narrowing keeps the valve from operating properly by not allowing the valve to fully open. With the aortic valve not working correctly, it causes extra stress on the valve.…

these drugs are currently involved in an enormous class action lawsuit as a result of their debilitating side effects. Plaintiffs in the multidistrict litigation claim to have suffered from serious conditions such as peripheral neuropathy, aortic aneurysms, and aortic dissection as a result of taking these medications. Some of these side effects even result in permanent injury. Although the FDA required that peripheral neuropathy be cited as a side effect on the warning labels…

Examination of Ventricular Septal Defects and Arterial Aneurysms According to Maternal Child Nursing Care, 5th Edition, Chapter 47 – Cardiovascular Dysfunction, congenital heart defects occur in about 5 to 8 of every 1000 live births, and 2 to 3 of those affected will be symptomatic within the first year of life (Hockenberry, 2014). When looking at the different pathophysiologies of congenital heart defects, the most common form of defect is the ventricular septal defect or VSD and there are…

In the aortic wall, stress is defined as force (F) per unit cross-sectional area, it mainly includes tension, which is stress that acts to dilate the aorta, and shear stress, which is stress that acts parallel to a surface. Strain is defined as deformation per unit of the original length, a relative change in shape or size, which is the ratio of the change caused by the stress to the original state of the aortic wall. And thus, the stiffer the aorta is, the…

Endovascular aortic repair (EVAR) is a less invasive treatment operation for patients with abdominal aortic aneurysms (AAAs). (1) The procedure involves the placement of an expandable stent graft within the aorta to treat aortic disease without operating directly on the aorta. Comparing EVAR with an open surgical procedure, it has been seen that in the first of these procedures, postoperative inflammatory response is attenuated. This accompanied with a technological improvement in stent graft…

Congenital aortico-left ventricular tunnel (ALVT) is rare and similar to ruptured sinus of Valsalva aneurysm. There are limited reports describing these rare entities and their associated surgical treatment. Between July 2004 and April 2016, three patients of different ages were diagnosed with aortico-left ventricular tunnel: two in infancy and one in adulthood. Diagnosis was challenging in all three patients. Surgical treatment with patch closure was successful in all three patients. Regardless…

within an abdominal aortic aneurysm (AAA) attenuates oxygen diffusion to the AAA wall, possibly causing localized hypoxia and contributing to wall weakening. The purpose of this work was to investigate this possibility. Methods: In one arm of this study, patients with AAA were placed in one of two groups: (1) those with an ILT of 4- mm or greater thickness on the anterior surface or (2) those with little (< 4 mm) or no ILT at this site. During surgical resection but before aortic…
