Aorta-to-left ventricle tunnel associated with noncompaction left ventricle.

We present a case of aorta-to-left ventricle (LV) tunnel and noncompaction LV in a 26-year-old woman. She was referred to our echocardiography laboratory for evaluation of aortic regurgitation by echocardiographic examination, which led to the diagnosis of the congenital abnormality of aorta-to-LV tunnel and noncompaction LV.
