Reversible subacute effusive-constrictive pericarditis after correction of double-chambered right ventricle: a case report.

A 15-year-old girl developed subacute constrictive pericarditis following successful surgical repair of double-chambered right ventricle. Two weeks after surgery, the patient had massive pericardial effusion, which acutely progressed to constrictive pericarditis with the symptoms of cardiac tamponade. Further surgery was necessary to resect the parietal pericardium. No blood transfusion was required for this patient, who was a Jehovah's Witness. She was doing well 9 months after the second operation, with residual pericardium of normal thickness.
