[The Gerbode defect - a left ventricle to right atrium communication].

We present a rare case of left ventricular to right atrial communication - a Gerbode type defect discovered in an adult man with systolic murmur at the left sternal border in physical exam. We report this case because this congenital defect is very rare, more often this pathology was reported after trauma, endocarditis or aortic valve replacement.
