Double ductus arteriosus and anomalous origin of the right pulmonary artery from the right-sided duct.

Double ductus arteriosus with anomalous origin of the right pulmonary artery is a rare congenital heart disease. Echocardiography is the first-choice method to diagnose pulmonary arteries and presence of the arterial ductus. Computed tomography (CT) angiography confirms the final diagnosis of the anomalous origin of the pulmonary artery. We report a case diagnosed using 40-slice CT angiography where this case demonstrated presence of both ducts and an anomalous origin of right pulmonary artery from the right-sided ductus arteriosus. <Learning objective: Anomalous origin of the right pulmonary artery usually presents in early infancy with heart failure and rapid development of pulmonary hypertension. An association of two patent arterial ducts and an anomalous origin of the right pulmonary artery from the right-patent arterial duct is a rare finding. Computed tomography angiography is the best diagnostic modality to establish the correct diagnosis, which is crucial for further decision-making and optimal patient management.>.
