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…

Every year, thousands people get heart valve replacements. There are multiple options for replacement valves that can be generalized as either mechanical or biological. One of the mechanical options from the 1970s and 1980s was the Bjork-Shiley valve, which became infamous because of the controversy surrounding its stress fracture failures. These failures resulted the death of about 400 people, causing the valve to be taken off the market. The decisions made leading to this issue must be…

Analysis of Materials and Biocompatibility of the Carpentier Edwards Magna Ease Aortic Heart Valve Chelsea Gibbs University of Utah Statement of Purpose: This report will look at the biomaterials used in the Carpentier-Edwards Perimount Magna Ease Aortic Heart Valve (CEPME) (Edwards Lifesciences LLC, Irvine, CA) and some of the biocompatibility issues found with this device. The CEPME bioprosthesis is designed to replace a diseased aortic heart valve that is no longer functioning properly and…

pulmonic, aortic stenosis, and hypertrophic cardiomyopathy. Physiologic murmur is a temporary increase of blood flow located at the left sternal boarder and the apex. Pulmonic stenosis murmur happens from impeded blood flow across the pulmonic valve. Aortic stenosis murmur ensue when stenosis of the aortic valve obstructs blood flow due to a congenital abnormality, or rheumatic fever. Pan-systolic murmurs are pathological in nature. Mitral regurgitation happens when the mitral valve do not…

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…

For example when a para sternal long axis 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…

Assessing Heart and Neck Vessels Physiology Blood usually flows through the heart silently, but when there is a swooshing or blowing sound heard upon auscultation it is referred to as turbulent blood flow (Weber & Kelley, 2014). This occurs in a variety of conditions such as 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…

Heart murmurs are constantly diagnosed in people, but what do heart murmurs do? Does it harm the host? It all depends on the type. From there, we dig deeper. According to http://www.madsci.org/posts/archives/1999-08/933633819.Me.r.html, Heart murmur is the sound that 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,…

Coronary Artery Disease Levi Gatherwright Morehead State University Coronary Artery Disease Coronary Artery Disease, CAD for short, is caused by a buildup of plaque in the coronary arteries that supply the heart with oxygenated blood. The plaque (Atheroma) is a waxy like substance that consists of calcium, lipid compounds, and blood clotting compounds such as macrophages and fibrin. The buildup takes many years to accumulate; the plaque eventually swells the arterial wall restricting blood…

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…
