"Where is the Heart?" When Cardiac Magnetic Resonance Imaging Helps if Echocardiography is Inconclusive.

ABSTRACT

Cardiovascular magnetic resonance (CMR) is the gold standard technique to comprehensively assess cardiac structure and function. A 64-year-old male, planned for surgical coronary revascularization, underwent transthoracic and transesophageal echocardiography for a mitral regurgitation, with an eccentric jet of unclear mechanism; these examinations were inconclusive because of the lack of adequate visualization of the cardiac structures. A CMR was then performed to quantify mitral regurgitation and, additionally, it documented a giant hiatus hernia with gastric sliding into the thorax. In this case, CMR helped to better define the severity of a valvular disease and provided ancillary information from the extracardiac findings.
