Postoperative bleeding is common after cardiac surgery. Major bleeding (MB) is a determinant of red blood cell (RBC) transfusion, especially in patients with preoperative anemia. Preoperative anemia and RBC transfusions are recognized risk factors for operative mortality. The present study investigates the role of MB as an independent determinant of operative mortality in cardiac surgery. ⋯ Major bleeding is per se a risk factor for operative mortality. However, its deleterious effects are strongly enhanced by RBC transfusions and, to a lesser extent, preoperative anemia. Major bleeding is a partially modifiable risk factor, and adequate preemptive and treatment strategies should be applied to limit this event.

Incidence of thrombosis in neonates undergoing cardiac surgery is as high as 20%, and single ventricle physiology (SVP) may present an even higher risk. We hypothesize that SVP is a risk factor for thrombosis in neonates undergoing cardiac surgery, and hypercoagulability biomarkers are predictive of postoperative thrombosis. ⋯ Single ventricle physiology patients are at higher risk for thrombosis compared with other neonates after cardiac surgery. Hypercoagulable panel testing may help risk stratify patients and guide patient specific anticoagulation management in the postoperative period.

We evaluated the current results and the predictors of in-hospital complications for a pericardiectomy procedure for constrictive pericarditis in Japan. ⋯ Pericardiectomy is associated with high morbidity and mortality rates. Careful consideration should be given to these risk factors in the process of patient selection and perioperative management.

In the middle of October 2011, the Hygiene Department of Caen University Hospital suspected an outbreak of surgical site infections (SSI) after open-heart operations with an unusually high proportion of microorganisms belonging to the Enterobacteriaceae family. The attack rate was 3.8%, significantly different (p = 0.035) from the attack rate of 1.2% in 2010 over the equivalent period. A case-control study was conducted to search specifically for risk factors for Enterobacteriaceae infections after median sternotomy in cardiac patients. ⋯ Although vancomycin is known to be effective for preventing infection with methicillin-sensitive organisms, our results suggest that it was associated with a risk for the development of SSI with gram-negative organisms after median sternotomy. This study led to a multidisciplinary meeting that defined new guidelines for prophylactic antibiotic therapy before open-heart operations.

We have shown previously that technical performance score (TPS) is strongly associated with early mortality and major postoperative adverse events in a diverse group of patients. We now report evaluation of the validity of TPS in predicting late outcomes in the same group of patients. ⋯ The TPS has a strong association with late outcomes across a wide range of age and disease complexity and may serve as a tool to identify patients who are at a higher risk for late reintervention or mortality.
