Congenital right ventricular outflow tract obstruction

Definition

A congenital cardiovascular condition in which the flow through the right ventricular outflow tract (proximal to the valve[s] guarding the outflow from the right ventricle) is blocked or impeded. Additional information: this code should not be used for obstruction immediately under the arterial valve(s) because specific codes exist for these entities, such as congenital subpulmonary and subaortic stenosis.
