Abstract: Objective To explore the diagnostic value of transthoracic echocardiography (TTE) for anomalous origin of right pulmonary artery (AORPA).Methods Echocardiographic data of 26 patients with AORPA proved by surgical operation were analyzed retrospectively.Results TTE showed that the pulmonary trunk and the left pulmonary artery were displayed normally,and the right pulmonary artery originated from the ascending aorta.AORPA in all 26 patients were diagnosed,and the coincidence rate was 100％.Among 26 patients,9 associated with Berry's syndrome,1 combined with coarctation of aorta,22 combined with patent ductus arteriosus,23 combined with atrial septal defect or patent foramen ovale,25 were found with severe pulmonary artery hypertension,and the diagnostic accuracy rate of TTE was 100％ (26/26),100％ (26/26),96.15％ (25/26),92.31％ (24/26) and 100％ (26/26),respectively.Conclusion TTE can early and accurately diagnose AORPA,also has high accuracy in diagnosis of other concomitant malformations.Multi-section scan can reduce misdiagnosis.TTE can be taken as the preferred inspection method for diagnosing AORPA.
