Clinics in diagnostic imaging (160). Levocardia with abdominal situs inversus

Levocardia (left-sided cardiac apex) with abdominal situs inversus is extremely rare. This is also known as isolated levocardia and is almost always associated with severe forms of congenital heart defects with poor prognosis. We report isolated levocardia in a 13-year-old symptomatic male patient. The purpose of this paper is to outline the imaging features of isolated levocardia and to highlight the role of cardiovascular magnetic resonance imaging (CMR) in the diagnosis and management of such cases. Other forms of cardiac malposition, including dextrocardia, mesocardia and criss-cross heart, with chest radiograph and CMR correlation, are also discussed.
