[Case report: 3D CT angiography in a patient with patent ductus arteriosus associated with Eisenmenger's syndrome].

Presentation of patent ductus arteriosus with Eisenmenger's syndrome can mimic primary pulmonary hypertension. The sensitivity of transthoracic echocardiography for the diagnosis of patent ductus arteriosus with Eisenmenger's syndrome has been estimated as low as 12%. Transesophageal echocardiography is superior to transthoracic echocardiography for the diagnosis of patent ductus arteriosus but has some severe complications. 3D CT angiography can be used to distinguish patent ductus arteriosus with Eisenmenger's syndrome from primary pulmonary hypertension.
