Right Ventricular Trabeculations on Echocardiography

A teenaged boy with no medical history developed intermittent palpitations, chest pain, and shortness of breath with normal findings on physical examination and normal laboratory test results (including cardiac troponins) and an electrocardiogram showing T-wave inversions in leads V1 through V3.

This video shows his echocardiogram, which revealed a severely dilated, dyskinetic right ventricle with trabeculations, diagnostic of arrhythmogenic right ventricular dysplasia/cardiomyopathy.
