Two-dimensional echocardiography (2-D) is a useful technique for noninvasive evaluation cardiac structure, function, and hemodynamics; however, multiple factors may limit the technical adequacy of the 2-D examination. In this article, we present the case of a ventricular septal defect to right atrial shunt, which was misinterpreted as severe tricuspid regurgitation secondary to severe pulmonary hypertension, despite the absence of right ventricular enlargement or hypertrophy. A transesophageal echocardiography (TEE) examination was performed to explain the discrepancy between the 2-D and Doppler findings, the results of which are discussed, along with a review of the literature.
