Severe truncal valve stenosis: diagnosis and management

Severe truncal valve stenosis, due to dysplastic valve, may be found in a small number of patients with truncus arteriosus. Its presence complicates the surgical management of this anomaly due to lack of optimal therapeutic options and associated ventricular dysfunction. We report a case of truncal root replacement using a homograft for the management of such condition, and review the literature related to its management and outcome.
