Criss-cross heart (CCH) is an extremely rare complex congenital heart malformation. It accounts for less than 0.1% of congenital heart diseases. Here, we describe a unique case of CCH with double-outlet right ventricle, huge subpulmonary ventricular septal defect, bicuspid pulmonary valve, and right-hand aortic arch. The anatomic features were observed with echocardiography, and the diagnosis was confirmed at surgery. Many variations of CCH have been described. The present case expands the spectrum of this entity and may provide new insight into this complex anatomy.
Keywords: aortic arch; bicuspid pulmonary valve; congenital cardiac defects; criss-cross heart; echocardiography.
