Congenitally corrected transposition of the great arteries: MDCT angiography findings and interpretation of complex coronary anatomy.

A 56-year-old male patient was admitted to our hospital because of dyspne and chest pain. A chest radiograph showed mild cardiomegaly. Echocardiography revealed unusual chamber in the heart. The chamber beneath the left atrium was morphologically right ventricle. To evaluate the precise complex anatomy of this abnormality, multidetector computed tomography (MDCT) angiography was performed. MDCT clearly revealed complex intracardiac and vascular anatomy, including typical imaging findings of a patient with congenitally corrected transposition of the great arteries (CCTGA). We described both imaging findings of MDCT angiography and interpretation of complex vascular anatomy in a patient with CCTGA.
