Acute kidney injury (AKI) is predictive of increased long-term mortality after cardiac surgery. Patients often undergo surgery after cardiac catheterization during the same admission for reasons of instability and threatening anatomy as well as nonurgent reasons such as patient convenience. We hypothesized that patients undergoing cardiac catheterization and cardiac surgery during the same admission are more likely to develop AKI after cardiac surgery than patients for whom surgery is performed on a later admission. ⋯ When cardiac catheterization and cardiac surgery occur during the same hospitalization, there is an increased risk for postoperative AKI. After cardiac catheterization, discharge and readmission for nonurgent surgery should be considered as such an approach might reduce the risk of AKI.

Extracorporeal membrane oxygenation (ECMO) is an effective technique to provide emergency mechanical circulatory or respiratory assistance in critically ill patients. A Mobile Remote Cardiac Assist unit was created to implant ECMO in patients from outside our institution and bring them back in our intensive care unit for follow-up when stabilized. This study was undertaken to evaluate the feasibility and the preliminary results of this procedure. ⋯ The Mobile Cardiac Assist unit allowed emergency implantation of ECMO support in remote institutions without any logistic or technical problems.

Left main coronary artery (LMCA) stenosis (≥50%) has historically been recognized as a risk factor among patients undergoing coronary artery bypass grafting. ⋯ Off-pump coronary artery bypass grafting is feasible and safe in patients with critical LMCA stenosis and LMCA disease is not recognized as a risk factor after off-pump coronary artery bypass grafting in either the short or the long term.

The effectiveness and safety of aprotinin in cardiac surgery has been questioned. The study aim was to compare both the blood-sparing effect and side effects of aprotinin and tranexamic acid in patients undergoing pulmonary endarterectomy. ⋯ In our experience of patients undergoing pulmonary endarterectomy, the tranexamic acid group had a higher median blood loss and more seizures. The trend to increased seizure frequency in the tranexamic acid group may be a direct consequence of this treatment, consistent with other recently published reports.
