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.

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.

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.

Review Case Reports
Extracorporeal venovenous membrane oxygenation in the treatment of respiratory insufficiency following cardiac surgery.
Following cardiac surgery, patients can develop acute respiratory failure. We present the case of a 66-year-old male successfully treated with extracorporeal venovenous membrane oxygenation (vvECMO) for acute respiratory failure postsurgery and review the literature on vvECMO in this specific setting.

Multiple blood products are often required during and after ventricular assist device (VAD) implants. Generally, transfusion therapy is empirically guided by conventional laboratory tests. In this study, we aimed to compare a thromboelastography (TEG)-based algorithm with a laboratory coagulation test-based algorithm with respect to blood product utilization in patients undergoing VAD implant. ⋯ Our results show that the strict use of a TEG-guided algorithm significantly reduces the consumption of blood products in patients undergoing VAD implant
