pulmonary valve replacement
Surgical procedure replacing a diseased pulmonary valve with a prosthetic valve or conduit.
Full Definition
Pulmonary valve replacement (PVR) is a cardiac surgical procedure involving removal of a diseased or absent pulmonary valve and implantation of a valve substitute. The procedure is commonly indicated in patients with congenital heart disease, particularly tetralogy of Fallot, or acquired pulmonary valve disease. Replacement options include homografts, xenografts, or valved conduits, with selection based on patient anatomy, age, and expected durability requirements.
