• tract
  • In right atrial isomerism, the pulmonary blood oxygen tract is damaged due to right-left shunting of blood. (wikipedia.org)
  • 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)
  • Aortic valve replacement using conventional cryopreserved homografts is currently performed only in about 3% of all patients, mostly to treat acute aortic valve endocarditis.1 Severe calcification of conventional homografts frequently occurs and is the main reason for its restrictive use, however, current guidelines confirm homografts as a valid alternative for young patients requiring anatomical reconstruction of the outflow tract.

  • Each cusp forms pocket like dilatation called pulmonary sinus at initial portion of pulmonary trunk Interior of right side of heart. (wikipedia.org)
  • A drawback of this method is that it can frequently result in a "two-valve" diseased heart, as almost all autografts are impaired by progressive dilatation in the long term, and the pulmonary valve prosthesis, often a conventional cryopreserved homograft, is subject to the same rate of degeneration as all biological valves.

  • The mitral valve gets its name from the resemblance to a bishop's mitre (a type of hat). (wikipedia.org)
  • During diastole, a normally-functioning mitral valve opens as a result of increased pressure from the left atrium as it fills with blood (preloading). (wikipedia.org)
  • As atrial pressure increases above that of the left ventricle, the mitral valve opens. (wikipedia.org)
  • This amount of blood is known as the end diastolic volume (EDV), and the mitral valve closes at the end of atrial contraction to prevent a reversal of blood flow. (wikipedia.org)

  • treatment of pulmonary
  • The treatment of pulmonary atresia consists of: an IV medication called prostaglandin E1, which is used for treatment of pulmonary atresia, as it stops the ductus arteriosus from closing, allowing mixing of the pulmonary and systemic circulations, but prostaglandin E1 can be dangerous as it can cause apnea. (wikipedia.org)
  • tetralogy
  • Play media The diagnosis of pulmonary valve stenosis can be achieved via echocardiogram, as well as a variety of other means among them are: ultrasound, in which images of the heart chambers in utero where the tricuspid valve has thickening (or due to Fallot's tetralogy, Noonan's syndrome, and other congenital defects) and in infancy auscultation of the heart can reveal identification of a murmur. (wikipedia.org)
  • The most common cyanotic heart defects include transposition of the great vessels, tetralogy of Fallot, persistent truncus arteriosus, tricuspid atresia and total anomalous pulmonary venous return. (wikipedia.org)
  • A number of cardiovascular defects may lead to Blue baby syndrome, including the following: Persistent (or patent) truncus arteriosus Transposition of the great vessels Tricuspid atresia Tetralogy of Fallot Anomalous pulmonary venous connection The most common cause of blue baby syndrome,[citation needed] and the one which was the subject of the classic "blue baby operation" developed at Johns Hopkins in the 1940s, is tetralogy of Fallot. (wikipedia.org)
  • atrial
  • Premature opening of the pulmonary valve (opening independent of atrial or ventricular systole) was originally described in a case of sinus of Valsalva rupture into the right atrium. (ahajournals.org)
  • Warfarin is an anticoagulan twhich is commonly used if your heart rate /pulse is irregular due to atrial fibrillation or if you have artificail heart valves placed in your heart.It prevents the risk of blood clots/ emboli which tend to form under the above two conditions and these emboli can lodge in the brain and cause a stroke . (healthtap.com)
  • arterial
  • Pulmonary arterial compliance was greater than normal in all groups, and the compliance in group 1B was more than two times that in the other groups. (ahajournals.org)
  • venous
  • The systemic venous return goes directly to the lungs, by-passing the heart.Very young children with elevated pulmonary vascular resistance may not able to undergo the Fontan procedure. (wikipedia.org)
  • lungs
  • From here it is pumped into the pulmonary circulation, through the lungs where it receives oxygen and gives off carbon dioxide. (wikipedia.org)
  • The valve is completely closed thereby obstructing the outflow of blood from the heart to the lungs. (wikipedia.org)
  • pulmonary atresia is not threatening to a developing fetus however, because the mother's placenta provides the needed oxygen since the baby's lungs are not yet functional. (wikipedia.org)
  • Once the baby is born its lungs must now provide the oxygen needed for survival, but with pulmonary atresia there is no opening on the pulmonary valve for blood to get to the lungs and become oxygenated. (wikipedia.org)
  • Circulation
  • Inhalation leads to an increase in intrathoracic negative pressure, which increases the capacity of pulmonary circulation, thereby prolonging ejection time. (wikipedia.org)
  • In this three-stage procedure, the right atrium is disconnected from the pulmonary circulation. (wikipedia.org)
  • severe
  • In one (7%) patient severe hypoxia and hypotension developed when the valve was crossed with a guide wire and balloon catheter. (bmj.com)
  • These blood thinners hold an inherent risk for severe bleeding episodes, which affects both professional and leisure activities and the majority of patients opt for mechanical valves for this reason. (wikipedia.org)
  • diagnosis
  • Potential risk factors that can cause this congenital heart defect are those the pregnant mother may come in contact with, such as: Certain medications Diet Smoking In regards to the diagnosis of pulmonary atresia the body requires oxygenated blood for survival. (wikipedia.org)

  • stent
  • The Melody valve is a bovine jugular vein valve sutured within a platinum iridium stent. (oncologynurseadvisor.com)
