Aortic valve

heart. These include defective heart valves, hypertrophic cardiomyopathy (enlarged heart muscle), holes or abnormal openings in the walls of the heart (septal defects), aortic aneurysm, or other congenital heart disease. This causes blood flow into the heart to be really slow and does not allow the affected person to live a long healthy life. Treatment of heart murmurs If a septal defect is causing the heart murmurs, corrective surgery may be required. If heart valve disease is causing the…

The Human Heart: A General Description The heart is the main organ of the cardiovascular system in the human body. Its primary function is to pump oxygen- and nutrient-rich blood throughout the 60,000 miles of blood vessels that make up this system ("Heart, 2015"). About the size of a clenched fist, the heart is located in the middle of the chest, between the lungs and nestled behind the ribcage. It lies a little to the left of the sternum. The shape of the heart is reminiscent of an upside…

her brother Jack Bicuspid lived, she was very eager to knock on his door because she loved her brother very much. She went forward and knocked on the door and her brother Jack opened the door(valve opens) saw her and gave her a BIG hug and asked her how she was, he invited her in and then shuts the door(valve closes). She walks around his home because she had never been in his home before so he shows her around(left ventricle) she loved it but after the tour she told him she was in a hurry to…

view is completed the left ventricle (LV), mitral valve and the mitral valve apparatus, the left atria (LA), left ventricular outflow, and the aortic valve (AV) are visualized (Fridman, Finkielstein, 2013). A TTE provides valuable information for determining the size and shape of the heart, the strength of pump, location of tissue damage, and determine if there any change in the pattern of blood flow. It is able to visualize all of the heart valves determine thickening, and calcific changes…

goes through the tricuspid valve and into the right ventricle. The tricuspid valve then closes when the ventricles is full then the right ventricle contracts, sending the blood to the pulmonary artery. From the pulmonary artery the blood goes to the lung and get oxygenated. The oxygenated blood, then flows into the left atrium through the pulmonary vein. Then the mitral valve opens up and the blood goes into the left ventricle. When the left ventricle is full the mitral valve closes and the…

Prosthetic Heart Valves for Pediatric Patients Madeline Setear, Biomedical Engineering, University of Rhode Island BME 181 First Presentation, March 6th, 2017 Abstract— Heart valve failure makes up a significant portion of Cardiovascular diseases. Heart valves fail when they are damaged and deteriorating or when they have congenital deformities. Heart valve replacement methods have improved greatly in the past decade. Currently, Mechanical and Biological Heart valve prosthesis exist but both…

Ever since I was a little girl, I always dreamed of helping others, and one of the jobs that would allow me to do this would be being a pediatric cardiovascular surgeon. Along with it being my dream job since I was eight, people who can fill this jobs role will be in high demand by the time I graduate if America stays on it’s fast food heavy diet. Caught in the growing concern in the medical center over this decline of the American diet, I learned of all the bad effects fats in our…

The Mechanics of the Heart An electrocardiogram, or EKG/ ECG, is a non-invasive test that measures the electrical activity of the heart and its electrical patterns. An electrical signal is sent through the heart to produce contractions that move the blood. This is what an EKG measures. In total that test may take from five to ten minutes and are ordered by a doctor to examine the heart more close. An EKG is done while the patient is lying down completely still (in order to reduce artifact or…

first trimester to become the heart. The heart is made up of four chambers: the right atrium, the left atrium, the right ventricle, and the left ventricle. There are two atrioventricular valves: the tricuspid valve in the right side and the mitral valve in the left side. There are also the pulmonary and aortic valves that originate from the right and the left ventricles. The heart is located in the mediastinum. During embryonic development, oxygenated blood from the placenta flows into the right…

Atrioventricular valves, or AV valves, are located between the atria and ventricles. Between the right atrium and right ventricle, the tricuspid valves exist; and the mitral valve separates the left atrium and left ventricle. Chordae Tendineae, which are attached to the AV valves and anchored to the papillary muscles, allow one-way flow by preventing eversion of the valves. Semilunar valves separate the ventricles from the arterial system. The aortic valve separates the left ventricle…
