  • Without the pulmonary valve, oxygenated blood flows from the lungs through other openings that traditionally close during development or shortly after birth. (childrens.com)
  • The circulation to and from the lungs is known as the 'Pulmonary circulation' and that around the body is the systemic circulation. (markedbyteachers.com)
  • In the pulmonary circulation, the pulmonary artery carrying deoxygenated blood leaves the right ventricle to go to the lungs and enters the left atrium. (markedbyteachers.com)

  • 1. Either surgical or percutaneous therapy can be useful in symptomatic patients with discrete RV pulmonary artery conduit obstructive lesions with greater than 50% diameter narrowing or when a bioprosthetic pulmonary valve has a peak gradient by Doppler greater than 50 mm Hg or a mean gradient greater than 30 mm Hg. (wikidoc.org)
  • 2. Either surgical or percutaneous therapy can be useful in asymptomatic patients when a pulmonary bioprosthetic valve has a peak Doppler gradient greater than 50 mm Hg. (wikidoc.org)
  • In two of our surgical patients, a protruding anterior tricuspid valve leaflet was identified and excised and both patients survived. (unipd.it)
  • A surgical procedure known as a valvuloplasty can stretch the pulmonary valve's walls to improve blood flow. (healthline.com)

  • With the increasing availability of cardiopulmonary bypass, surgical expertise, and intensive care facilities, valve repair and replacement are widely performed to relieve symptoms and improve prognosis of valvular heart disease, despite the associated morbidity and mortality. (medscape.com)
Catheter-based1
  • The minimally invasive procedure, which involves the implantation of the first-ever catheter-based pulmonary valve replacement, is currently performed by interventional cardiologists at Morgan Stanley Children's Hospital of NewYork-Presbyterian and Columbia University Medical Center-the only New York City site and one of only three sites nationally that is offering the procedure as part of an ongoing clinical research trial.

  • RESULTS: Percutaneous branch PA valve implantation was attempted in 34 patients (18 bilateral and 16 unilateral). (duke.edu)
  • Until percutaneous valve technology for large RVOTs is refined and more widely available, branch PA valve implantation remains an option for select patients. (duke.edu)
