Abstract
A 25-year-old woman who had undergone the Blalock-Taussig shunt operation for double-outlet right ventricle (DORV) in her childhood was admitted to our hospital with mild cyanosis and dyspnea on exertion. To evaluate the precise complex anatomy of this abnormality, we carried out multidetector computed tomography (MDCT) angiography. MDCT clearly revealed both an occluded Blalock-Taussig shunt and a complex cardiac anatomy, including DORV, a doubly committed ventriculoseptal defect, pulmonary stenosis, persistent left superior vena cava, minor aortic arch anomalies, and total anomalous hepatic venous drainage. To our knowledge, our report is the first description of such a complex cardiac anatomy to be revealed with MDCT.
