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.

The purpose of this study was to assess the efficacy and midterm results of endovascular treatment of acute, complicated type B aortic dissection. ⋯ Endovascular stent-graft placement in acute, complicated type B aortic dissection proves to be a promising alternative therapeutic treatment modality in this relatively difficult patient cohort. Refinements, especially in stent design and application, may further improve the prognosis of patients in this life-threatening situation.

Surgical treatment of an amniotic fluid embolism with cardiopulmonary collapse.
Amniotic fluid embolism is a rare but devastating condition associated with a very high rate of morbidity and mortality. The treatment has traditionally been aggressive supportive care. ⋯ The embolism was seen on transesophageal echocardiogram during an emergency Cesarean section as a free-floating interatrial clot through a patent foramen ovale. She was subsequently and successfully treated with immediate cardiopulmonary bypass, thromboembolectomy, and closure of the patent foramen ovale.

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.

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.
