Double-chambered right ventricle (DCRV) is an uncommon congenital heart condition characterized by a progressive obstruction in the right ventricular outflow tract. This obstruction is caused by anomalous muscles or fibrous tissues that divide the right ventricle into two cavities: a proximal high-pressure chamber (anatomically lower) and a distal low-pressure chamber (anatomically higher). We present a case of a middle-aged man with a medical history of recurrent symptomatic dyspnea. Upon presentation, there were no signs of congestive cardiac failure. The diagnosis was confirmed using transthoracic two-dimensional (2-D) echocardiography and Transesophageal echocardiography (TEE) for more precise characterization. The primary objective of this case report is to highlight the rarity of this congenital heart disease, particularly in adults.
