Aortic valve

Aortic Aneurysm 4.) Symptoms: Source: @healthline. "Aortic Aneurysm." Healthline. N.p., 26 Jan. 2016. Web. 14 Oct. 2016. In the early stages, aortic aneurysm may have no symptoms. As they grow larger, they may cause abdominal, chest, or back pain. Most go undiagnosed until they’re discovered during a routine doctor’s visit. A ruptured aneurysm, in contrast, is a medical emergency with serious symptoms. These can include sudden and intense pain in your abdomen, dizziness, clamminess, falling…

not at fault. Mitral valve prolapse is a condition that the cause is still unknown. Scientists believe it may be hereditary and people can be born with it, but never experience any symptoms. Even though mitral valve prolapse is not usually life-threatening, however some people may require treatment and a complete change of lifestyle. Mitral valve prolapse, or MVP, is defined as a valvular heart disorder. Where one or both mitral…

The mitral valve is the valve that regulates flow from the left atrium of the heart into the left ventricle. This valve is subject to a few different diseases and pathologies that affect its form and function. One of those diseases is mitral valve stenosis which is when the mitral opening between the left atrium and the left ventricle narrows and restricts the blood flow through it. The etiology, pathology and symptoms of mitral valve stenosis are well known and well documented which allows…

Different Effect of Mitral Valve Prolapse History of the Disease One of the most common cardiac abnormalities in the United States is Mitral Valve Prolapse, also known as MVP, which affects about 2-6% of Americans. It is a disorder of the bicuspid valve, which causes backflow of blood from the left ventricle back into the left atrium (Sims & Miracle, 2007). MVP can also be identified as click-murmur syndrome, floppy mitral valve, and Barlow syndrome (Kornusky & Cabrera, 2014). In past studies,…

Visual Prosthesis: Selling a Dream to Visually Impaired (A literature review of advancements in the field of Visual Prosthesis) Abstract Visual prosthesis is by far the best bet to restore vision in a patient suffering with visual loss. This paper provides a literature review of the various technological advancements made over time and how these advancements have proved noteworthy in fields of visual prosthesis. To develop a basic understanding about the visual prosthesis, the anatomy and…

Researching for life’s improvements is the goal for every engineer, this explains the countless hours engineers spend inside an office or a laboratory. Although people think of engineers as only creators of lifeless technology, many of biomedical engineers specialized in technology for the living. Meeting between medicine and engineering, biomedical engineers find solutions for medicine and, in some cases, people’s disabilities. These disabilities appear from accidents in the workplace to war…

A stenotic valve is a valve that has been narrowed due to excessive calcium. This can cause chest pain, chest tightness, heart palpitations, fatigue and shortness of breath.4 There are generally two types of valvuloplasty: Aortic valvuloplasty, and mitral valvuloplasty.4 These two procedures differ based on the type of valve that is being widened. For example, aortic valvuloplasty treats the narrowing of the aortic valve, or in other words the valve that is located between the left…

approach has beenevolving and is changing the face of medicine. Transcatheter Valve Replacement (TVR), is apercutaneous technique that uses fluoroscopic guidance to replace a diseased or dysfunctionalvalve without ever having to go under the knife. To be able to intervene percutaneously is the“most exciting advancement in the treatment of valve disease” (Kenny & Hijazi, 2013, p795).The pulmonary valve and aortic valve are two valves that can be treated or replaced in thecatheterization lab…

known history of bicuspid aortic valve disease. On his arrival to the hospital, his temperature was 38.5 degrees celsius, heart rate was 98 bpm, and his blood pressure fell in the normal range at 100/80 mmHg. The man’s breathing sounded normal and a systolic murmur was found. Transesophageal echocardiography showed the man’s bicuspid valve with small vegetation that was attached to the ventricular leaflet. There was also a grade 2 aortic regurgitation and an 8mm aortic ring abscess. They…

contraction, which is the stage where ventricles begin contracting, the aortic and semilunar valves close which prevents a change in volume. The fourth stage, ventricular ejection, is the moment where the ventricles are emptying themselves through contractions. The final stage is called the isovolumic relaxation time, during this stage pressure decreases, no blood enters the ventricles, the ventricles then begin relaxing and the semilunar valves close due to pressure of blood found in the aorta.…
