| Abstract: | Three patients with patent ductus arteriosus and moderate aortic stenosis had a marked reduction in aortic valve gradient
following transcatheter ductal occlusion. The hemodynamic effects of an aortopulmonary shunt on the severity of left ventricular
outflow obstruction and the implications on intervention are discussed. |
