  • The valves of the heart prevent the backflow of blood between the heart's chambers. (scopeheal.com)
  • There are four valves in the heart: the aortic valve, the mitral valve, the tricuspid valve, and the pulmonary valve. (scopeheal.com)
  • The aortic valve is usually surgically replaced by stopping the heart. (scopeheal.com)
  • A surgical technique that avoids opening the heart can be used to treat valve diseases that present a narrowing. (scopeheal.com)
  • Sometimes, medication is not enough to treat heart failure (cardiac insufficiency) effectively. (herzkinder.at)
  • Open-heart surgery is not required. (herzkinder.at)
  • The most serious complication of ARF is development of rheumatic heart disease, which most commonly manifests as mitral valve stenosis. (lecturio.com)
  • The aortic valve is between the left verticle (also called the lower chamber of heart pumping) and the aorta, the most extensive artery in the body. (expertchikitsa.com)
  • Valves control on way blood flow from the heart. (expertchikitsa.com)
  • Both echocardiography and computed tomography scanning demonstrated migration of the aortic valve into the left ventricle, causing severe aortic and mitral (secondary) insufficiency. (qxmd.com)
  • Infection of the valve can occur, which is dangerous and difficult to treat. (wikipedia.org)
  • An infection in the lining of the heart's walls and valves (the endocardium). (wikidoc.org)
  • Of the children, 20 underwent repair, whilst we replaced the valve in 31 patients. (istanbul.edu.tr)
  • Results: There were neither early nor late deaths in those who underwent mitral valvar repair. (istanbul.edu.tr)
  • We present cases of chronic Q fever that were not diagnosed until after the patients underwent cardiac valve surgery. (cdc.gov)
  • It happens most often in elderly patients and commonly affects the mitral valve. (wikidoc.org)
  • When symptomatology is experienced by the patient, an appearance of the symptoms most commonly reported depend on whether or not tricuspid valve insufficiency is directly related to left ventricular dysfunction . (symptoma.com)
  • To date, one of the most commonly used prosthetic ring is the commercially available Carpentier-Edwards Physio II mitral ring (CE ring), which comes in 9 different sizes (size 28-40) [ 3 ]. (biomedcentral.com)
  • Minimally invasive mitral valve surgery is much more technically demanding and may involve higher risk. (wikipedia.org)
  • But some cardiac surgeons argue that unless performed by the most experienced cardiac centers, minimally invasive surgery can involve a longer time on a bypass machine, a lower repair rate, and higher (although still low) risk of stroke. (wikipedia.org)
  • Few of them have underlying rheumatic valve disease. (scirp.org)
  • Surgery for mitral valvar disease in childhood: should we choose reconstruction or repair? (istanbul.edu.tr)
  • Surgery for mitral valvar disease in chi. (istanbul.edu.tr)
  • To increase understanding of the role of Q fever in valvular cardiac disease, we present 3 cases of chronic Q fever and valvular cardiac disease requiring surgery in patients from the Netherlands. (cdc.gov)
  • According to recent estimates, more than 79,000 patients are diagnosed with aortic and mitral valve disease in U.S. hospitals each year. (justia.com)
  • Symptoms depend on the patient and the type and severity of valve disease. (wikidoc.org)
  • In other cases, valve disease may take its toll over many years. (wikidoc.org)
  • Before doctors started giving their patients antibiotics, rheumatic fever was the single biggest cause of valve disease. (wikidoc.org)
  • The biennial meeting brings the world's leading experts together to examine all aspects of mitral valve disease, associated conditions, and treatment. (mountsinai.org)
  • Tricuspid valve insufficiency may be asymptomatic in patients with moderate, or even severe, stage of the disease. (symptoma.com)
  • It is often the case that the disease is silent and that the patient is not necessarily aware of the signs of valve disease. (scopeheal.com)
  • Oral microorganisms may also enter the deeper tissue after trauma or surgery, which contributes to the disease process, particularly when they cause BE. (medscape.com)
