• leaflets
  • At surgery patent oval foramen was found and pulmonary valve was stenotic with malformation of four valve leaflets and a mass in left thoracic cavity was confirmed to be pulmonary sequestration through pathologic examination. (minervamedica.it)
  • The pulmonary valve is made up of three thin leaflets arranged in a circle, much like a three-piece pie. (knowyourdisease.com)
  • In valvular pulmonary stenosis, one or more of the leaflets may be defective or too thick, or the leaflets may not separate from each other properly. (knowyourdisease.com)
  • Stenosis can also result in insufficiency if thickening of the annulus or leaflets results in inappropriate leaf closure. (wikipedia.org)
  • Stenosis of the aortic valve is characterized by a thickening of the valvular annulus or leaflets that limits the ability of blood to be ejected from the left ventricle into the aorta. (wikipedia.org)
  • This defect is characterized by the presence of only two valve leaflets and affects up to 1% of the population, making it one of the most common cardiac abnormalities. (wikipedia.org)
  • Processes that lead to aortic insufficiency usually involve dilation of the valve annulus, thus displacing the valve leaflets, which are anchored in the annulus. (wikipedia.org)
  • diagnosis
  • It provides diagnosis and treatment of congenital heart diseases, acquired valvular heart diseases, rare structural heart diseases, including interventional treatment of heart valve diseases. (bookinghealth.com)
  • In the diagnosis of pulmonary insufficiency both echocardiograms and EKG is used to ascertain if the individual has this condition, as well as, the use of a chest x-ray to expose enlargement of the right atrium or ventricle. (wikipedia.org)
  • occur
  • Irrespective of disease process, alterations to the valve occur that produce one or a combination of these conditions. (wikipedia.org)
  • neonates
  • Effects of Balloon Valvuloplasty on Coronary Blood Flow in Neonates With Critical Pulmonary Valve Stenosis Assessed With Transthoracic Doppler Echocardiography. (lu.se)
  • CONCLUSIONS: RV end-diastolic pressure and RV systolic pressure determined coronary flow in neonates with critical pulmonary valve stenosis. (lu.se)
  • author = {Aburawi, Elhadi and Berg, Ansgar and Pesonen, Erkki}, issn = {1097-6795}, language = {eng}, pages = {165--169}, publisher = {Elsevier}, series = {Journal of the American Society of Echocardiography}, title = {Effects of Balloon Valvuloplasty on Coronary Blood Flow in Neonates With Critical Pulmonary Valve Stenosis Assessed With Transthoracic Doppler Echocardiography. (lu.se)
  • Percutaneous balloon dilatation gave effective relief of critical pulmonary stenosis in most neonates but complications and restenosis requiring surgery were common. (bmj.com)
  • arteries
  • The defects can involve the walls of the heart, the valves of the heart, and the arteries and veins near the heart. (icdlist.com)
  • blood flow
  • Normally, these valves open to let blood flow through or out of your heart, and then shut to keep it from flowing backward. (icdlist.com)
  • If this happens, the valve doesn't open correctly, restricting blood flow. (knowyourdisease.com)
  • Proper positioning and function of the valves is critical for chamber formation and proper blood flow. (wikipedia.org)
  • Anatomically, the valves are part of the dense connective tissue of the heart known as the cardiac skeleton and are responsible for the regulation of blood flow through the heart and great vessels. (wikipedia.org)
  • systemic
  • Extralobar pulmonary sequestration is a type of congenital pulmonary developmental malformation defined as an isolated cystic solid mass with unbroken and separate pleural investment and a systemic arterial supply, and no communication with the normal bronchial tree. (minervamedica.it)
  • They also experience complications with systemic and pulmonary blood vessels, significant morbidity, and sometimes death. (wikipedia.org)
  • diseases
  • One of the main focuses of the d epartment is the treatment of heart valve diseases. (bookinghealth.com)
  • The main objectives of pulmonologists are to diagnose and treat lung and pleural diseases, obstructive diseases (asthma, chronic obstructive bronchitis), inflammatory and autoimmune interstitial lung diseases (pulmonary fibrosis of various etiologies) and lung cancer. (bookinghealth.com)
  • Aortic and mitral valve disease are termed left heart diseases. (wikipedia.org)
  • mitral valve
  • Mitral valve prolapse - when one of the valves, the mitral valve, has "floppy" flaps and doesn't close tightly. (icdlist.com)
  • In these cases the left ventricle of the heart becomes enlarged and causes displacement of the attached papillary muscles, which control the mitral valve. (wikipedia.org)
  • abnormal
  • Murmurs may also be the result of various problems, such as narrowing or leaking of valves, or the presence of abnormal passages through which blood flows in or near the heart. (wikipedia.org)
  • tract
  • These impairments, in addition to congestion in the pulmonary tract, allows deoxygenated blood to mix with oxygenated blood, contributing to cyanosis and possible respiratory distress. (wikipedia.org)
