Usefulness of Live/Real Time Three-Dimensional Transthoracic Echocardiography in Diagnosing Acquired Left Ventricular-Right Atrial Communication Misdiagnosed as Severe Pulmonary Hypertension by Two-Dimensional Transthoracic Echocardiography

We describe an adult patient with an acquired left ventricular-right atrial communication that was misdiagnosed as severe pulmonary hypertension (PH) by two-dimensional (2D) transthoracic echocardiography, but accurately detected on three-dimensional (3D) transthoracic echocardiography. Open heart surgery confirmed the defect. (ECHOCARDIOGRAPHY, Volume 26, February 2009).
