Abstract
There have been significant advances in percutaneous interventions for congenital heart disease over the last 30years. In this first article we will focus on ventricular outflow obstructions. Among left ventricular outflow tract obstructions, stent repair of coarctation of aorta and supravalvular aortic stenosis offer percutaneous solutions. Balloon valvuloplasty for aortic valve stenosis and balloon tearing of a thin discrete subaortic stenosis are also alternatives to surgery. Among right ventricular outflow tract obstructions, balloon valvuloplasty for pulmonary stenosis is currently the gold standard for treatment. For homograft degeneration after surgery of the outflow tract, pulmonary valve implantation (Melody) may avoid further surgical interventions. Stent implantation for pulmonary branch stenosis is the treatment of choice for this congenital disease or post-surgical pathology.
