[Gerbode defect or left ventricular to right atrial shunt. Case report and literature review].

Gerbode defect is a communication from the left ventricle to right atrium and it could be categorized in congenital or acquired. It is a rare condition that can represent as much as 0.08% of all septal defects. Those acquired defects can be associated to endocarditis and after valvular surgery. The objective is to report a case of Gerbode atria-ventricular septal defect in Instituto Nacional de Cardiología Ignacio Chavez. The present case is about a 36 years old male patient with a typical presentation of mitral regurgitation, the echocardiogram reports a perforation in the anterior mitral leaflet and a Gerbode ventricular septal defect, that represents the heterogeneity of the clinical presentation of this pathology, also we show the findings in imaging studies that contributed to diagnosis and its surgical resolution. Gerbode defect is an uncommon pathology, many times associated to other cardiovascular entity, difficulting diagnose. It requires image studies and a complete presurgical evaluation in order to achieve opportune diagnosis.
