Brain infarction with a predilection for cerebellum in a patient with double-outlet left ventricle and vascular malformations.

Double-outlet left ventricle (DOLV) is a rare congenital heart disease characterized by the origin of the great arteries arising predominantly or completely from the left ventricle. In this report, we describe a case with brain infarction with a predilection for cerebellum in a patient with DOLV and vascular malformations. The cerebellar predilection of ischemic lesions appeared to have been caused by hemodynamic effects related to the specific anatomy of the brachiocephalic trunk. This is further supported by our observation that the mean flow velocity was significantly higher in the vertebral arteries than in the common carotid arteries.
