Percutaneous Stent Placed in Main Pulmonary Artery for Pulmonary
Percutaneous expansile stents can be used to achieve patency of stenotic lumens. In this case the ribs of a stent are visible in the proximal pulmonary artery which had been congenitally
stenotic.
Color doppler in short axis view of the RVOT and proximal pulmonary artery shows adequate flow through the
stent.
2D short axis view of the RVOT and proximal pulmonary artery shows the ribbed pattern of the frame of the
stent.
