Mitral regurgitation

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…

The mitral valve (MV) plays a crucial role in cardiac function, controlling blood flow between the left atrium and left ventricle. The components of the valve include an anterior leaflet, a posterior leaflet, tendinous chords, papillary muscles, and a saddle shaped annulus at the atrioventricular junction.[1] Deviation in the morphology of any of these components of the valve may result in comprised mechanical integrity of the valve and abnormal leaflet closure.[1] With studies suggesting that…

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 &…

particularly dangerous form of heart disease is mitral regurgitation (MR) which affects 200,000 people every year in the US alone. The Mitral valve is a key site of failure due to its location between the left atrium and left ventricle, it prevents the backflow of oxygenated blood into the atrium during ventricular systole and constantly experiences high pressures. MR is the backflow of blood into the atrium and pulmonary veins due to the partial or complete mitral valve failure. This failure is…

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…

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…

They are both comprised of cardiac muscles which contract involuntarily to pump blood. Each side of the heart contains valves which prevent the regurgitation of blood. The left and right side of the heart have a mutual muscular segment by which they are separated and is known as the atrioventricular septum. Differences between Left and Right Side of the Heart? • Left side of the heart operates 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 also took blood samples, and decided to start antibiotic therapy. Four of the blood samples had gram-negative cocci growth within a day, so they switched the treatment to ceftriaxone and…

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,…

Clinical Context and Experience On 9/20 and 9/30 I completed my third and forth shift on 7 West at Sharp Memorial Hospital. Although these were not my first shift on the unit they were my first shift with my regular preceptor Elle. The first two shifts I was working with Laura who was my temporary preceptor, while Elle was on vacation. The first night was calm because of low census and the second night it was a bit busier throughout the night. On our first shift together we were the resources…
