Left ventricle

From the subjective data collected through history taking and objective data gathered from the physical assessment of Mr Jones, the primary differential diagnosis was AR. The left ventricle in AR is typically dilated from secondary to severe volume overload, normally the left ventricle handles both the forward flow delivered from the left atria as well as the backflow of blood from the aorta. The abnormal backflow of blood leads to pathologic changes in the heart in order to compensate for the decreased successful cardiac output . Aortic regurgitation occurs from either damage to the aortic valve leaflets or dilation of the aortic annulus (Otto, 2014). Symptoms are generally radical and usually exacerbated by a racing heart palpitations,…

help resolve some of the malfunctions of the human heart. One of the most popular devices recently invented to support one of the functions of the heart is the Left Ventricle Assist Device. What is Left…

developed from birth though symptoms of the condition may not be present until adulthood. During the time of birth the closure of the ductus arteriosus (DA) should occur about 15 hours after birth though functional closure may be delayed for up to 3 months of life. Thus, an open DA is the functional indicator of congenital heart disease. The primitive heart tube undergoes adjustments in the first trimester to become the heart. The heart is made up of four chambers: the right atrium,…

of four chambers, the right atrium, right ventricle, left atrium and the left ventricle. The right atrium is the chamber which receives blood from the body that has been depleted from its oxygen and pumps it to the right ventricle. The right ventricle then pumps the blood from the right atrium over to the pulmonary artery which as the name would suggest means it goes to the lungs and the oxygen depleted blood is once again oxygenated. The left atrium of the heart then receives the blood that has…

Introduction Mitral valve regurgitation, also called mitral regurgitation, is a condition in which blood leaks from the mitral valve in the heart. The mitral valve is located between the upper left chamber of the heart (left atrium) and the lower left chamber of the heart (left ventricle). Normally, this valve opens when the atrium pumps blood into the ventricle, and it closes when the ventricle pumps blood out to the body. Mitral valve regurgitation happens when the mitral valve does not close…

Hypertrophic cardiomyopathy (HCM) is the most common form of feline cardiomyopathies. This disease affects the cardiovascular system. The heart has many important anatomical features. One of these being the ventricle of the heart. The ventricle of the heart is the main heart muscle that pumps blood. When HCM occurs the left ventricle within the heart thickens. When the thickening of the ventricle occurs there will be a decreased ventricular chamber volume, and abnormal ventricular relaxation.…

Single Ventricle Defects WHAT ARE SINGLE VENTRICLE DEFECTS? Single ventricle defects are heart problems that you were born with (congenital heart defects). Normally the heart has two pumping chambers. These are the right and left ventricles. The right ventricle pumps blood to the lungs to get oxygen. After blood returns from the lungs, the left ventricle pumps it out to the body. Single ventricle defects come in many forms. They can involve one or more valves in your heart and a ventricle…

Ghost Hearts Doris A. Taylor, inventor/creator of the ghost hearts constantly harvest organs from the newly dead by re-engineering them. Doris is the director of the regenerative Medicine Research for the center of Cell and Organ Biotechnology at the Texas Heart Institute. Dr. Taylor worked on methods of decellularization and in 2008 she perfected the method. Decellularization is taking all the cells out of the organ leaving it with the lipids, sugar, and proteins. Ghost heart or a ghost-like…

Mechanical Heart valves are designed to mimic natural heart valves as closely as possible. The valve is implanted in the heart of the patient where the damaged heart valve was removed. Artificial heart valves allows for correct blood flow through the heart by opening and closing with each heartbeat (St Jude Medical, n.d.). The Medtronic mechanical heart valve contains two leaflets (Medtronic, 2011). The pressure in the heart causes the leaflets to open and close, allowing blood flow in only…

great vessels is a heart condition that is present in infants at birth and often known as a congenital heart defect or the more common term is the transposition of the great arteries(TGA). TGA is when the two main arteries, the pulmonary artery and the aorta, are switched in position, or "transposed". As a normal heart, deoxygenated blood returning to the heart from the body is pumped from the right side of the heart through the pulmonary artery to the lungs and to the left side of the heart…
