Effects of Pulmonary Vasodilation Upon VA Coupling in Fontan Patients

Summary

The study involves documenting the effects of inhaled nitric oxide upon ventricular-arterial coupling in patients with congenital heart disease and passive pulmonary blood flow. Consenting patients undergoing a clinically-indicated cardiac catheterization will be given inhaled nitric oxide for 10 minutes while intraventricular pressure-volume analysis will be make via conduction catheters.
