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.

Seminal Postoperative Complications and Mode of Death After Pediatric Cardiac Surgical Procedures.
Understanding the seminal complications leading to death after pediatric cardiac surgical procedures may provide opportunities to reduce mortality. This study analyzed all deaths at two pediatric cardiac surgical programs and developed a method to identify the seminal complications and modes of death. ⋯ Seminal complications occurred early postoperatively, and systemic circulatory failure was the most common mode of death. Our classification system is likely scalable for subsequent multicenter analysis to understand cause-specific mortality variation across hospitals and to drive quality improvement.

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.

The purpose of this analysis was to revise the model for perioperative risk for esophagectomy for cancer utilizing The Society of Thoracic Surgeons General Thoracic Surgery Database to provide enhanced risk stratification and quality improvement measures for contributing centers. ⋯ Thoracic surgeons participating in The Society of Thoracic Surgeons General Thoracic Surgery Database perform esophagectomy with low morbidity and mortality. McKeown esophagectomy is an independent predictor of combined postoperative morbidity or mortality. Revised predictors for perioperative outcome were identified to facilitate quality improvement processes and hospital comparisons.

Minimally Invasive Mitral Valve Surgery Provides Excellent Outcomes Without Increased Cost: A Multi-Institutional Analysis.
Minimally invasive mitral valve surgery (mini-MVR) has grown in popularity. Although single centers have reported excellent outcomes, data on real-world outcomes and costs of mini-MVR are limited. Moreover, mini-MVR has been criticized as adding additional cost without clear benefit. We hypothesized that mini-MVR provides superior outcomes with incremental increased costs in a multi-institutional cohort. ⋯ Compared with conventional sternotomy, mini-MVR in the "real world" demonstrated no differences in rates of major morbidity, but it was associated with shorter length of stay and fewer transfusions. Contrary to our hypothesis, mini-MVR can be performed with similar total hospital costs as conventional sternotomy. In summary, minimally invasive mitral surgical procedure in select patients can provide superior outcomes without increased cost.
