Arrhythmogenic biventricular cardiomyopathy: emerging findings on cardiac CT performed in the emergency department to evaluate chest pain.

We present multimodality imaging findings demonstrating arrhythmogenic biventricular cardiomyopathy initially observed on cardiac CT in a patient who presented to the emergency department with nonanginal chest pain. As the volume of patients referred for coronary CT angiography increases, structural pathology may emerge in previously unencountered diagnostic sequences. The high spatial resolution and volumetric coverage afforded by multidetector CT imaging remind us that cardiac pathology encompasses far more than atherosclerosis.
