Simplified technique for pericardial patch of the right ventricular outflow tract

Pericardial patching to enlarge the right ventricular outflow tract is often required in congenital cardiac surgery in lesions such as tetralogy of Fallot, pulmonary atresia, pulmonary stenosis, and pulmonary artery repair following removal of a palliative pulmonary artery band. A method of simplifying the attachment of the pericardial patch onto the right ventricular outflow tract is described.
