The provider implants a pulmonary valve percutaneously, through an incision through the skin and into the heart, as an alternative to an open procedure for pulmonary valve replacement. The provider typically performs this procedure on patients who have previously had pulmonary valve repair for congenital heart disease when the repaired valve no longer functions properly. He may place a stent at the valve site to keep it open before performing the replacement.
