The Society of Thoracic Surgeons Congenital Heart Surgery Database (STS CHSD) is the largest congenital and pediatric cardiac surgical clinical data registry in the world. The most recent biannual feedback report to participants includes analysis of data submitted from 125 hospitals, representing nearly all centers performing pediatric and congenital heart operations in the United States and Canada. In addition to serving as a platform for reporting of outcomes and for quality improvement, the database continues to be a primary data source for clinical research and for innovations related to quality measurement. ⋯ Additional ongoing projects involve the development of new or refined metrics for quality measurement and reporting of outcomes and center level performance. To meet the needs of investigators, the STS Research Center and Workforce on Research Development has created multiple pathways through which investigators may propose and, ultimately, perform outcomes research projects based on STS CHSD data. This article reviews published outcomes research and quality improvement projects from the past year and describes ongoing research related to quality measurement.

Meta Analysis Comparative Study
A Systemic Review and Meta-Analysis of Sutureless Aortic Valve Replacement Versus Transcatheter Aortic Valve Implantation.
Sutureless aortic valve replacement (SU-AVR) and transcatheter aortic valve implantation (TAVI) are increasingly adopted methods to treat high-risk patients with severe aortic valve stenosis. We conducted a systematic review and meta-analysis to compare the clinical outcomes between these two recent methods to treat aortic valve disease. ⋯ Our meta-analysis of observational studies demonstrates that early mortality is lower after SU-AVR than after TAVI in selected patients. The rates of stroke and pacemaker implant are comparable between procedures; however, the incidence of paravalvular leak is higher after TAVI.

Meta Analysis
Rigid Plate Fixation Versus Wire Cerclage for Sternotomy After Cardiac Surgery: A Meta-Analysis.
Traditionally, wire cerclage has been used to reapproximate the sternum after sternotomy. Recent evidence suggests that rigid plate fixation for sternal closure may reduce the risk of sternal complications. ⋯ This meta-analysis, driven by the results of unmatched observational studies, suggests that rigid plate fixation may lead to reduced sternal complications in patients at high risk for such events, improved perioperative survival, and decreased hospital length of stay. More randomized controlled trials are required to confirm the potential benefits of rigid plate fixation for primary sternotomy closure.

Simulation-based training has been an important part of the solution to address the shortfalls in cardiac surgery training. This review was conducted to identify and systematically summarize existing evidence on outcomes and methodological quality of simulation-based skills training for cardiac surgery trainees. ⋯ Of 16 studies that met the criteria, only four (25%) randomized controlled trials were identified, and the remaining were observational studies. Seven observational studies (43.7%) were single-group pre-post tests. The mean number of trainees was 20.4 (SD, 14.1). Low-fidelity simulators were used in 13 studies (81.2%). Most of the studies (81.3%) were high quality based on a Medical Education Research Study Quality Instrument score of 12 or more. Evidence of assessment tool validation was absent among all studies. No study outcome measures were directed to skills transfer to the operating room or patient outcomes. Overall learning outcomes' effect sizes were consistently high (2.2; SD, 1.6), with junior residents benefitting most (effect size, 2.8; SD, 2.2) CONCLUSIONS: Simulation-based skill training is associated with improved learning outcomes for cardiac surgery trainees with large effect sizes, but more behavior-level outcomes are required to fully assess its value.

Despite more than a half century of "safe" cardiopulmonary bypass (CPB), the evidence base surrounding the conduct of anticoagulation therapy for CPB has not been organized into a succinct guideline. For this and other reasons, there is enormous practice variability relating to the use and dosing of heparin, monitoring heparin anticoagulation, reversal of anticoagulation, and the use of alternative anticoagulants. To address this and other gaps, The Society of Thoracic Surgeons, the Society of Cardiovascular Anesthesiologists, and the American Society of Extracorporeal Technology developed an Evidence Based Workgroup. ⋯ The quality of information for a given recommendation allowed assessment of the level of evidence as recommended by the American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines. Recommendations were written in the three following areas: (1) heparin dosing and monitoring for initiation and maintenance of CPB; (2) heparin contraindications and heparin alternatives; and (3) reversal of anticoagulation during cardiac operations. It is hoped that this guideline will serve as a resource and will stimulate investigators to conduct more research and to expand on the evidence base on the topic of anticoagulation therapy for CPB.
