Figure 1From: Truncus arteriosus with aortic arch interruption: cardiovascular magnetic resonance findings in the unrepaired adultA three-dimensional volume-rendered magnetic resonance angiogram; anterolateral (A) and posterior (B) views demonstrate anatomy consistent with Type II truncus arteriosus and interruption of the aortic arch (Type B). TA: truncus arteriosus; Ao Asc: ascending aorta; Ao Desc: descending aorta; RPA: right pulmonary artery; LPA: left pulmonary artery; LCA: left common carotid artery; LS: left subclavian artery; PDA: patent ductus arteriosus; IA: innominate arteryBack to article page
