Echocardiographic guidance for neonatal right ventricular outflow tract stent implantation.

The use of combined fluoroscopic and echocardiographic imaging in congenital intervention is a well-established and developing concept. We report the case of a 1.2 kg, hemodynamically unstable neonate with tetralogy of Fallot, in whom we implanted a right ventricular outflow tract stent under primarily echocardiographic guidance. This represents the smallest reported patient in whom a right ventricular outflow tract stent has been placed and the latest application of integrated echocardiography and fluoroscopy in the catheterization laboratory.
