Given substantial advances in venovenous extracorporeal membrane oxygenation (ECMO) technology, long-term support is increasingly feasible. Although the benefits of short-term ECMO as a bridge to recovery in acute respiratory distress syndrome (ARDS) are well described, the utility and outcomes of long-term support remain unclear. ⋯ Previously, long-term ECMO support was thought to be associated with unfavorable outcomes. This study, however, may provide support for the efficacy of ECMO support even for 3 weeks or more as a bridge to recovery or transplantation.

The use of a right ventricle-to-pulmonary artery (RV-PA) conduit for stage 1 palliation of hypoplastic left heart syndrome is common. A prospective randomized multiinstitutional study revealed that approximately 40% of those receiving this shunt required intervention on the shunt or pulmonary arteries, or both. ⋯ We present a new technique to improve distal conduit stenosis and decrease anastomotic bleeding from this site. The technique involves dunking a segment of the shunt into the pulmonary arteries and suture placement in the shunt rings and not in the polytetrafluoroethylene (PTFE).

Treatment of infected pacing leads ranges from percutaneous extraction to surgical removal with the use of cardiopulmonary bypass (CPB). Vena caval inflow occlusion (VCIO) is an old technique that has been used with success in the pediatric population. We report on the use of inflow occlusion (IO) in removing infected pacing leads from the right side of the heart in patients in whom endovascular lead extraction failed. VCIO is a safe and simple technique in patients with infected leads who have contraindications for CPB.

Randomized Controlled Trial Multicenter Study
Intraoperative High-Dose Dexamethasone in Cardiac Surgery and the Risk of Rethoracotomy.
Cardiac surgery with the use of cardiopulmonary bypass is associated with a systemic inflammatory response. Intraoperative corticosteroids are administered to attenuate this inflammatory response. The recent Dexamethasone for Cardiac Surgery (DECS) trial could not demonstrate a beneficial effect of dexamethasone on major adverse events in cardiac surgical patients. Previous studies suggest that corticosteroids may affect postoperative coagulation and blood loss, and therefore could influence the risk of surgical reinterventions. We investigated the effects of prophylactic intraoperative dexamethasone treatment on the rate of rethoracotomy after cardiac surgery. ⋯ Intraoperative high-dose dexamethasone administration in cardiac surgery was associated with an increased rethoracotomy risk.
