A Rare Cause of Right Heart Failure in An Adult: Congenital Gerbode Defect.

Gerbode defect is a rare defect describing a left ventricle to right atrium shunt with symptoms dependent on the size and degree of the shunt. It is either a congenital defect detected in infancy, or an acquired case reported in older age. Diagnosis by means of echocardiography and cardiac magnetic resonance imaging is of paramount importance before surgical correction is contemplated to achieve a good prognosis.
