Truncus arteriosus with aortic arch interruption: cardiovascular magnetic resonance findings in the unrepaired adult

David Verhaert et al. J Cardiovasc Magn Reson. .

Abstract

Truncus arteriosus (TA) is a rare congenital condition defined as a single arterial vessel arising from the heart that gives origin to the systemic, pulmonary and coronary circulations. We discuss the unique case of a 28 year-old female patient with unrepaired TA and interruption of the aortic arch who underwent cardiovascular magnetic resonance (CMR).
