Background: The double outlet right ventricle is uncommon and usually makes patients have haemodynamic and structural complications. Having a hyperdynamic state, such as pregnancy, with volume overload is very risky for a patient with complex CHD (CCHD). The diagnosis in early stages can prevent cardiac complications. The multi-disciplinary assessment of the disease lets patients make choices in treatment and reproductive life. Objective: Present a case of a successful pregnancy in a patient with a rare CCHD. Participant: A pregnant 19-year-old patient with a double outlet right ventricle without haemodynamic or structural complications and no fetal abnormalities.
