We have previously shown that early primary repair of tetralogy of Fallot can be performed without increased morbidity or resource utilization. The technical performance score (TPS) is a self-assessment tool used to identify patients at risk of poor postoperative outcomes. We hypothesized that adequate technical repair can be obtained regardless of the patient's preoperative age or size. ⋯ Technical adequacy of tetralogy of Fallot repair is affected by anatomic subsets (discontinuous branch pulmonary arteries) and not by the patient's age or size. Worse TPS is associated with higher postoperative morbidity and hospital charges. Younger age and size should not be a deterrent for early primary repair.

The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II was developed to reflect a more current dataset and evidence-based improvements in cardiac surgery. In the United States, The Society of Thoracic Surgeons (STS) risk score is more accepted owing to relatively high predictive value despite less user friendliness and inapplicability to some cardiac surgeries. We compared the precision of EuroSCORE II with EuroSCORE I and the STS risk score for operative mortality. ⋯ EuroSCORE II had better predictive discrimination for operative mortality than EuroSCORE I, which greatly overestimated this risk. EuroSCORE II fared well compared with the STS risk score. The inclusive nature of EuroSCORE II for numerous procedures provides more flexibility than the STS score for complex procedures. EuroSCORE II should be considered for calculating risk score for complex cardiac surgical patients.

Multicenter Study Observational Study
Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement for Severe Aortic Stenosis in Patients With Chronic Kidney Disease Stages 3b to 5.
There are scarce data on outcomes after transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) in patients with renal failure. ⋯ CKD stages 3b to 5 increases the risk of mortality after TAVI and SAVR. In this subset of patients, SAVR was associated with somewhat better early and late survival. The risk of acute kidney injury was higher after SAVR. These findings suggest that CKD stages 3b to 5 does not contraindicate SAVR. Strategies to prevent severe acute kidney injury should be implemented with either SAVR or TAVI.

Effects of Blood Transfusion on Cause-Specific Late Mortality After Coronary Artery Bypass Grafting-Less Is More.
Red blood cell transfusion after coronary artery bypass graft surgery has been associated with increased late all-cause death. Yet, whether this association is, first, independent of the packed red blood cells and perioperative morbidity association, and second, of a cardiac versus noncardiac etiology remains unknown. ⋯ Perioperative red blood cells transfusion is associated with significant adverse late death effects among both complicated patients and noncomplicated patients, principally seen between 0 and 5 years postoperatively, and is driven by both increased cardiovascular and noncardiovascular mortality. Further studies are needed to elucidate the mechanisms behind these findings, including their potential dose dependence.

Failure to Rescue Rates After Coronary Artery Bypass Grafting: An Analysis From The Society of Thoracic Surgeons Adult Cardiac Surgery Database.
Failure to rescue (FTR) is increasingly recognized as an important quality indicator in surgery. The Society of Thoracic Surgeons National Database was used to develop FTR metrics and a predictive FTR model for coronary artery bypass grafting (CABG). ⋯ CABG mortality rates vary directly with FTR, but complication rates have little relation to death. FTR rates derived from The Society of Thoracic Surgeons data can serve as national benchmarks. Predicted FTR rates may facilitate patient counseling, and FTR O/E ratios have promise as valuable quality metrics.
