Transatrial repair of double-chambered right ventricle

Seventeen consecutive patients with double-chambered right ventricles underwent intracardiac repair from February, 1985 through March, 1989. Nine patients had an associated ventricular septal defect. A transatrial approach to the repair was utilized in all patients. Early postoperative right ventricular-to-left ventricular pressure ratio was a mean of 0.29, range 0.21 to 0.37. There were no hospital or late deaths. We conclude that transatrial repair of a double-chambered right ventricle can be accomplished routinely with satisfactory results.
