Brief 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.

Outcome Measures
Primary Outcomes (1)
Effective arterial elastance (Ea)
Patients will undergo hemodynamic evaluation while receiving inhaled nitric oxide. After the measurements are made the nitric oxide will be discontinued. The primary outcome is the change in effective arterial elastance, a value obtained from ventricular pressure-volume assessment, before and while receiving nitric oxide.
Acute, approximately 10-15 minutes
Study Arms (1)
inhaled nitric oxide

- All consecutive patients with single ventricle hearts having passive pulmonary blood flow presenting to the cardiac catheterization laboratory for clinically indicated cardiac catheterization.
You may not qualify if:
- Patients with coarctation of the aorta or known bilateral femoral arterial obstruction
- Patients with known severe systemic venous/Fontan obstruction
- Patients already receiving sildenafil or other vasodilator therapy
