The aim of this study is to evaluate acute kidney injury (AKI) after total aortic arch repair (TAR) with moderate hypothermic circulatory arrest (MHCA) and selective antegrade cerebral perfusion (SACP). ⋯ Postoperative AKI stratified by RIFLE criteria was significantly associated with short- and mid-term outcomes in TAR with MHCA and SACP.

To compare cardiopulmonary exercise capacity of patients undergoing primary total cavopulmonary connection (TCPC) with those undergoing TCPC after a prior bidirectional Glenn (BDG). ⋯ There were no differences in the exercise parameters of patients undergoing a staged versus a primary TCPC, fenestrated versus nonfenestrated TCPC, and age at surgery less than or more than 7 years. Exercise parameters were better in the extracardiac conduit group versus lateral tunnel TCPC groups. Patients who had a TCPC after prior interruption of APBF had better exercise parameters.

Extracorporeal membrane oxygenation can be done through several cannulation sites. Axillary artery cannulation is commonly performed through a Dacron graft sutured in an end-to-side fashion to the axillary artery. Direct cannulation of the axillary artery appears a reliable technique with low rate of complications. We report our experience in 16 patients using the direct cannulation technique.

Observational Study
Influence of circulating levels of fibrinogen and perioperative coagulation parameters on predicting postoperative blood loss in cardiac surgery: a prospective observational study.
Fibrinogen, the major clotting protein in blood plasma, plays key roles in blood coagulation and thrombosis. In this prospective cohort study, we measured patient's fibrinogen levels and common coagulation parameters before and after cardiopulmonary bypass (CPB) and examined their relationships with postoperative blood loss. ⋯ Postoperative fibrinogen, the larger percent decrease in fibrinogen, and postoperative platelet levels are markers of bleeding and blood transfusion requirements after CPB than preoperative standard screening tests. Postoperative fibrinogen had the best predictive value of all tests of postoperative blood loss.

Pulmonary artery slings are rare congenital anomalies seen only on the left side. The presence of right pulmonary artery (RPA) sling is extremely rare. We report a case of a RPA sling with a single lung associated with tracheal stenosis and its management.
