Despite remarkable advances in transcatheter pulmonary valve replacement, most patients with congenital heart disease who develop postoperative right ventricular outflow tract (RVOT) dysfunction (pulmonary insufficiency and/or obstruction) are ineligible for treatment with the current approaches and technologies due to anatomic complexities that make it technically impossible to implant a valve in the orthotopic (usual) pulmonary position via a transcatheter approach. Therefore open-heart surgery is required to restore pulmonary valve competence. Our group is investigating several novel minimally invasive approaches to pulmonary valve replacement. The ultimate goal is to expand the choices that are available to clinicians charged with treating these complex patients.
