The aim of the present study was to evaluate the current outcome and reoperation rate after applying a one-stage correction strategy for interrupted aortic arch (IAA) with ventricular septal defect (VSD) and also for aortic coarctation and hypoplastic aortic arch (CoA-HyAA) with VSD beginning September 1999. ⋯ One-stage complete correction is feasible in newborns with aortic arch obstruction with VSD. Complex cardiac anatomy presents no additional risk for the procedure. The early one-stage correction yields excellent surgical results and good functional outcome.

For lobectomy patients at considerable risk of developing a postoperative bronchopleural fistula, the bronchial stump reinforcement with an intercostal muscle flap is sometimes performed. This procedure usually requires a standard thoracotomy, even if video-assisted thoracoscopic surgery (VATS) is better for the patient. ⋯ No postoperative complications were observed. This procedure is applicable to patients who are candidates for VATS lobectomy.

Despite significant improvement in survival after stage 1 Norwood, interim mortality before the second-stage operation remains significant. On the basis of reports of improved circulatory stability associated with the use of a right ventricle to pulmonary artery conduit, the difference between two physiologically different sources of pulmonary blood flow on interim mortality was investigated. ⋯ The use of a right ventricle to pulmonary artery shunt decreases the incidence of interim mortality among hospital survivors after stage 1 Norwood for hypoplastic left heart syndrome. Aortic atresia, the use of a modified Blalock-Taussig shunt, and perioperative dysrhythmias are independently associated with a higher mortality before superior cavopulmonary connection.

Case Reports
Severe argatroban-induced coagulopathy in a patient with a history of heparin-induced thrombocytopenia.
Heparin-induced thrombocytopenia is a serious complication of heparin therapy, and it remains a therapeutic challenge in the subset of patients requiring cardiopulmonary bypass. Alternative anticoagulation strategies include lepirudin, danaparoid, bivalirudin, and argatroban, or a combination of unfractionated heparin with a platelet antagonist. ⋯ We present a patient with a history of heparin-induced thrombocytopenia with thrombosis who underwent a redo aortic valve replacement. Although the level of anticoagulation achieved with argatroban was initially adequate, its persistence after the completion of cardiopulmonary bypass proved to be life threatening.
