A case of double-chambered right ventricle associated with an interventricular septal aneurysm in an elderly patient.
Double-chambered right ventricle is a congential malformation caused by an anomalous muscle band obstructing the right ventricular outflow tract. Most reported cases of this condition have been diagnosed in infants, or adolescents. We encountered a 61-year-old woman with a double-chambered right ventricle, associated with a large interventricular septal aneurysm, which is a rare complication. The right ventricular obstruction was corrected with surgery.
