Aortic valve stenosis

What conditions contribute to turbulent blood flow or heart murmurs. Turbulent blood flow occurs as blood moves through narrowed or leaking valves producing a swooshing sound over the precordium and a high heart rate combine with narrowing, causing the heart to handle a larger amount of blood flow than normal; the basis is increased blood velocity, structural valve malfunction, or atypical chambers. Some pathological causes of heart murmurs are anemia, high blood pressure, overactive thyroid,…

hand is a tube composed of metal that can remain within the body to keep a blood vessel open. Interventional cardiology is said to be first discovered by Andreas Gruentzig in 1977 when he widened part of an abnormally narrowed, a condition called stenosis, left anterior descending artery through the use of a balloon catheter.3 Previously any treatment of the heart required open heart surgery which put the patient in high risk…

increased blood velocity, structural valve defects, valve malfunctions, and abnormal chamber openings (Weber & Kelley, 2014). The heart has four chambers two atria, which are the upper chambers of the heart and two ventricles, which are the lower chambers of the heart. They are then further divided into left and right. Between the upper and lower chambers there are valves to prevent backflow of blood. Between the right atrium and right ventricle tricuspid valve and between…

When a thrill is prominent and widespread, application of the entire palm of the hand is helpful in sensing the direction of radiation. An aortic stenotic thrill radiates upward and to the right, and a pulmonary stenotic thrill radiates upward and to the left. If a thrill is localized, relatively firm application of a fingertip usually suffices for detection.” (Perloff). The distal metacarpals…

is made because the blood passing through the heart’s valves and chambers make a sound. Sometimes, the valve doesn’t open entirely, and the blood goes back to the chamber it just left. When that happens, it makes a swishing noise, making it easy to find. Generally, heart murmurs are not exactly dangerous, unless it is abnormal. Abnormal heart murmur is caused, in children, by congenital heart disease. Adults may get it as well by heart valve problems. People do not naturally…

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…

Hypertrophic cardiomyopathy (HCM) is the second most common form of heart muscle disease and is the number one cause of sudden cardiac death in young athletes. It affects approximately one in 500 adults in the United States. HCM is a genetically determined heart muscle disease caused by more than 1400 mutations in 11 or more genes encoding proteins of the cardiac sarcomere (Maron & Maron, 2013). HCM is characterized by left ventricular hypertrophy (LVH) of various morphologies with a wide…

Physiology Murmurs are the product of intense blood flow across inflexible, calcified valves; faulty valves that permit reverse blood flow (regurgitation); faulty (deviant openings) in the septum, aorta, or pulmonary artery; or abnormally high velocity of blood flow through a normal structure. Supposedly blood generally flows soundlessly through the heart; yet, these conditions can generate tumultuous blood flow resulting in auscultation of swooshing or gusty sound over the precordium (Weber &…

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…

Pulse pressures that exceed 40 mm Hg, like in the case of Gerhardt, is a risk factor for cardiovascular diseases such as mitral valve regurgitation or valvular pulmonic stenosis.2,3 The presence of the soft mid-systolic murmur near the upper left sternal border was also suggestive of valvular pulmonic stenosis.3 However, Gerhardt’s prolonged PR interval of 0.62 seconds, bradycardia and systolic murmur could also be due to an increased vagal tone commonly seen in…
