Mitral valve

The human body is composed of eleven major systems that all work together to hold a stable internal environment: homeostasis. Each system consists of different organs that all play important roles in maintaining homeostasis. The circulatory, respiratory and renal systems greatly affect each other in the keeping of the internal environment. Homeostasis is defined as the tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to…

10 to 30 minutes. For healthy patients, this is an unimportant factor, however bacteremia poses a risk in patients with prosthetic cardiac valves, previous bacterial endocarditis, surgically constructed systemic-pulmonary shunts, most congenital cardiac malformations, rheumatic and other acquired valvular dysfunction, hypertrophic cardiomyopathy, mitral valve prolapse with valvular regurgitation, synthetic vascular grafts and prosthetic joints [ortho2]. The prevalence of bacteremia is observed…

On June 23, 1858 a well established Medical Practitioner named Antoine Prosper Marfan and his wife Adelaïde Thuries bought a new life into the world. Antoine Prosper and Adelaide’s son was named Antoine Bernard-Jean Marfan. Bernard’s father, Antoine Prosper had refused to accept his son’s choice in pursuing a career in the medical field. Prosper later gave up on arguing with his son and Bernard went off to study at a medical school in Toulouse, France. Two years went by and Bernard decided to go…

“Welcome To –“read a sign that was found standing in front of a pathway leading into a lively town. Of course the sign advertised the name of the town but the old man didn’t seem to care to read it. He was a wanderer, he wandered endlessly with no destination because he didn’t have one; he didn’t have anything. He was old and had gray hair. His face was withered and his eyes were cold; almost mechanical. All of life’s hardships had taken its toll on him and it showed, for every wrinkle, there…

Que: 1 Describes the components and conduction pathway of the cardiac conduction system of the heart.relate the cardiac condution system to the corresponding sequence of heart chamber contractions. The cardiac conduction system refers to a group of specialized muscle cells of the heart’s wall (Assadi, 2013). The cells are meant to send signals to the cardiac muscles thus contraction. The major components of the cardiac conduction system are the Atrioventricular node, sinuatrial node, the bundle…

system, principally cardiac disease, vascular diseases of the brain and kidney, and peripheral arterial disease. The causes of cardiovascular disease are diverse but atherosclerosis and/or hypertension are the most common. In addition, with aging come a number of physiological and morphological changes that alter cardiovascular function and lead to increased risk of cardiovascular disease, even in healthy asymptomatic individuals. Heart attacks and strokes are usually acute events and are mainly…

Background Progeria is an extremely rare form of dwarfism, affecting a mere 200-250 children worldwide at a time (Gordon, 2013).Classically known as Hutchinson-Gilford progeria syndrome, HGPS is a disease that causes the body to "prematurely age". Manifestations of this disease affects the skin, musculoskeletal system, and vasculature. The term progeria is derived from the Greek word geras, meaning "old age" (Shah, 2015). Dr. Jonathan Hutchinson first described this syndrome in 1886, and…

reported, the correlation amongst the genotype-phenotype hasn’t yet been made. “Affected individuals get diagnosed during birth or thereafter, with unique features like ‘crumpled’ external ears, loose skin, congestive heart failure from mitral and tricuspid valves back flowing in the…

Final impression found mildly dilated left ventricle with normal wall thickness and normal systolic function with an estimated ejection fraction is fifty to fifty-five percent. Thickened mitral valve with mild to moderate aortic stenosis and mild regurgitation is also present with an aortic valve area of 2.0 cm2 and a mean gradient of 11mmHg. Lastly mild left atrial and right atrium enlargement. The patient also had a White Blood Cell Local Study NM which is an imaging test that uses a…

Patient comes into the Emergency Room with a chief complaint of swelling and extreme pain in the left leg. After awaiting triage, the patient is finally seen by the physician. Temperature 96.8˚F, Heart Rate 129 beats per minute, Blood Pressure 102/60, Respiratory Rate 23, SPO2 100% on room air. Upon examination of his left leg, it is undeniably blue in color with significant swelling as compared to the right. Superficial veins are noticeably distended and the leg is cool to the touch. A Duplex…
