Percutaneous pulmonary valve implantation in left pulmonary artery branch in a patient with a functional single lung.

Percutaneous pulmonary valve technology has had a great impact on patients with congenital and acquired heart disease. In some patients, implantation of a percutaneous pulmonary valve may not be possible due to the morphology of the existing right ventricular outflow tract. In this report, we describe implantation of a Melody transcatheter pulmonary valve in the left pulmonary artery in a patient with acquired right pulmonary artery occlusion and a large right ventricular outflow tract.
