No publication linked
No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
The study will test the hypothesis that a single dose of sildenafil can increase the exercise capacity of pediatric patients with a Fontan Circulation.
