This study was designed to compare findings of ivus imaging and those of angiography of the pulmonary artery before and after the balloon angioplasty procedure. The valve of the pulmonary artery is made up of three thin leaflets, and its job is to control the flow of blood from the heart to the main pulmonary artery. The characteristic hemodynamic feature of pulmonary stenosis is an increased systolic pressure gradient between the pulmonary artery and the right ventricle 1,2.
