Congenital Left Ventricular-Right Atrial Communication Gerbode-Type Defect.

Adult congenital heart diseases present a unique challenge in assessing right-sided cardiac chambers, where pressures can be mistakenly calculated using standard echocardiographic formulae. A challenging case is presented of a combined inlet ventricular septal defect and ventriculo-atrial Gerbode defect. The diagnosis of such adult congenital heart diseases requires an in-depth understanding of cardiac pathophysiology and hemodynamics. Video 1: Transthoracic echocardiography.
