title: Anomalous right ventricular muscle bundle. Repair through the right atrium.
abstract: Anomalous muscle bundles within the right ventricle may cause obstruction to blood flow at the level of the outflow tract. This condition is usually associated with a ventricular septal defect. Although complete correction is usually approached through a right ventriculotomy, the anatomic configuration makes repair through a right atriotomy more suitable. The advantages of this approach are discussed and a case report is presented.
