Abstract
Background Patients with congenital heart disease are at risk of motor, cognitive, speech, and feeding difficulties after cardiac surgery. Rehabilitation therapy could improve functional outcomes in this population if applied in the acute postcardiac surgical in‐hospital stay. However, information on the types of acute postcardiac surgery therapy needs in children is scarce. Our goal was to describe rehabilitation therapy following congenital heart surgery and pre/intraoperative factors associated with need for therapy. Methods and Results This is a retrospective cohort study of patients <18 years undergoing heart surgery at our center from January 1, 2013 to January 31, 2015. Demographic, and pre‐, intra‐, and postoperative clinical and rehabilitation therapy (physical, occupational, speech, feeding therapy, and neurodevelopment intervention) data were collected. Need for rehabilitation therapy in the acute postoperative period, particularly following palliative repair, was the outcome variable in a multivariable logistic regression model to identify independent pre‐ and intraoperative factors associated with therapy. A total of 586 out of 1415 (41%) subjects received rehabilitation therapy postsurgery. Certain subgroups had increased rehabilitation therapy use such as neonates (80%). On multivariable analysis, palliative repair, prematurity, genetic syndrome, presurgical hospital stay of more than 1 day, and prolonged cardiopulmonary bypass time were independently associated with rehabilitation therapy. Conclusions Nearly half of patients who underwent post–congenital heart surgery received rehabilitation therapy. Frequency of use and types of therapy vary according to patient characteristics; however, certain pre‐ and intraoperative factors are associated with need for rehabilitation therapy, and may aid decision‐making for appropriate resource allocation.

Abstract
BACKGROUND Synthetic graft materials are commonly used for shunts and cardiovascular reconstruction in neonates, but are prone to thrombosis and scarring. The umbilical vein is a potential source of autologous, endothelialized tissue for neonatal shunts and tissue reconstruction, but requires preservation before implantation. METHODS Umbilical cords were collected in UW solution with antibiotics at 4°C until dissection. Umbilical vein segments were tested for burst pressure before and after 2 weeks of preservation. Umbilical veins segments were preserved under static or flow conditions at 4°C in UW solution with 5% human plasma lysate for 7 days. Veins were evaluated with histopathology, scanning electron microscopy, and platelet adhesion testing. RESULTS Umbilical veins have no difference in burst pressure at harvest (n = 16) compared with 2 weeks of preservation (n = 11; 431 ± 229 versus 438 ± 244 mm Hg). After 1 week, static and flow-preserved veins showed viability of the vessel segments with endothelium staining positive for CD31, von Willebrand factor, and endothelial nitric oxide synthase. Scanning electron microscopy demonstrated preservation of normal endothelial morphology and flow alignment in the flow-preserved samples compared with cobblestone endothelial appearance and some endothelial cell loss in the static samples. Static samples had significantly more platelet adhesion than flow-preserved samples did. CONCLUSIONS Umbilical veins have adequate burst strength to function at neonatal systemic pressures. Preservation under flow conditions demonstrated normal endothelial and overall vascular morphology with less platelet adhesion compared with static samples. Preserved autologous umbilical veins are potential source for endothelialized shunts or cardiovascular repair tissue for neonates.

Abstract
OBJECTIVES This paper provides detailed instructions for constructing low-cost bioprosthetic semilunar valves for animal research and clinical training. This work fills an important gap between existing simulator training valves and clinical valves by providing fully functioning designs that can be employed in ex vivo and in vivo experiments and can also be modified to model valvular disease. METHODS Valves are constructed in 4 steps consisting of creating a metal frame, covering it with fabric and attaching a suture ring and leaflets. Computer-aided design files are provided for making the frame from wire or by metal 3D printing. The covering fabric and suturing ring are made from materials readily available in a surgical lab, while the leaflets are made from pericardium. The entire fabrication process is described in figures and in a video. To demonstrate disease modelling, design modifications are described for producing paravalvular leaks, and these valves were evaluated in porcine ex vivo (n = 3) and in vivo (n = 6) experiments. RESULTS Porcine ex vivo and acute in vivo experiments demonstrate that the valves can replicate the performance of clinical valves for research and training purposes. Surgical implantation is similar, and echocardiograms are comparable to clinical valves. Furthermore, valve leaflet function was satisfactory during acute in vivo tests with little central regurgitation, while the paravalvular leak modifications consistently produced leaks in the desired locations. CONCLUSIONS The detailed design procedure presented here, which includes a tutorial video and computer-aided design files, should be of substantial benefit to researchers developing valve disease models and to clinicians developing realistic valve training systems.

Abstract
BACKGROUND Resource utilization in congenital heart surgery is typically assessed using administrative data sets. Recent analyses have called into question the accuracy of coding of cases in administrative data; however, it is unclear whether miscoding impacts assessment of associated resource use. METHODS We merged data coded within both an administrative data set and clinical registry on children undergoing heart surgery (2004-2010) at 33 hospitals. The impact of differences in coding of operations between data sets on reporting of postoperative length of stay (PLOS) and total hospital costs associated with these operations was assessed. RESULTS For each of the eight operations of varying complexity evaluated (total n = 57,797), there were differences in coding between data sets, which translated into differences in the reporting of associated resource utilization for the cases coded in either data set. There were statistically significant differences in PLOS and cost for seven of the eight operations, although most PLOS differences were relatively small with the exception of the Norwood operation and truncus repair (differences of two days, P < .001). For cost, there was a >5% difference for three of the eight operations and >10% difference for truncus repair (US$10,570; P < .01). Grouping of operations into categories of similar risk appeared to mitigate many of these differences. CONCLUSION Differences in coding of cases in administrative versus clinical registry data can translate into differences in assessment of associated PLOS and cost for certain operations. This may be minimized through evaluating larger groups of operations when using administrative data or using clinical registry data to accurately identify operations of interest.

Abstract
PURPOSE There remains a paucity of direct visualization techniques for beating-heart intracardiac procedures. To address this need, we evaluated a novel cardioscope in the context of aortic paravalvular leaks (PVLs) localization and closure. DESCRIPTION A porcine aortic PVL model was created using a custom-made bioprosthetic valve, and PVL presence was verified by epicardial echocardiography. Transapical delivery of occlusion devices guided solely by cardioscopy was attempted 13 times in a total of three pigs. Device retrieval after release was attempted six times. Echocardiography, morphologic evaluation, and delivery time were used to assess results. EVALUATION Cardioscopic imaging enabled localization of PVLs via visualization of regurgitant jet flow in a paravalvular channel at the base of the prosthetic aortic valve. Occluders were successfully placed in 11 of 13 attempts (84.6%), taking on average 3:03 ± 1:34 min. Devices were cardioscopically removed successfully in three of six attempts (50%), taking 3:41 ± 1:46 min. No damage to the ventricle or annulus was observed at necropsy. CONCLUSIONS Cardioscopy can facilitate intracardiac interventions by providing direct visualization of anatomic structures inside the blood-filled, beating-heart model.

Abstract
Strategies to value physician work continue to evolve. The Society of Thoracic Surgeons and The Society of Thoracic Surgeons National Database have an increasingly important role in this evolution. An understanding of the Current Procedural Terminology (CPT) system (American Medical Association [AMA], Chicago, IL) and the Relative Value Scale Update Committee (RUC) is necessary to comprehend how physician work is valued. In 1965, with the dawn of increasingly complex medical care, immense innovation, and the rollout of Medicare, the need for a common language describing medical services and procedures was recognized as being of critical importance. In 1966, the AMA, in cooperation with multiple major medical specialty societies, developed the CPT system, which is a coding system for the description of medical procedures and medical services. The RUC was created by the AMA in response to the passage of the Omnibus Budget Reconciliation Act of 1989, legislation of the United States of America Federal government that mandated that the Centers for Medicare & Medicaid Services adopt a relative value methodology for Medicare physician payment. The role of the RUC is to develop relative value recommendations for the Centers for Medicare & Medicaid Services. These recommendations include relative value recommendations for new procedures or services and also updates to relative value recommendations for previously valued procedures or services. These recommendations pertain to all physician work delivered to Medicare beneficiaries and propose relative values for all physician services, including updates to those based on the original resource-based relative value scale developed by Hsaio and colleagues. In so doing, widely differing work and services provided can be reviewed and comparisons of their relative value (to each other) can be established. The resource-based relative value scale assigns value to physician services using relative value units (RVUs), which consist of three components: work RVU, practice expense RVU, and malpractice RVU, also known as professional liability insurance RVU. The Centers for Medicare & Medicaid Services retains the final decision-making authority on the RVUs associated with each procedure or service. The purpose of this article is to discuss the role that the CPT codes and the RUC play in the valuation of physician work and to provide an example of how the methodology for valuation of physician work continues to evolve.

Abstract
Significant progress has been made for tissue imaging of proteins using matrix-assisted laser desorption ionization imaging mass spectrometry (MALDI IMS). These advancements now facilitate mapping of a wide range of proteins, peptides, and post-translational modifications in a wide variety of tissues; however, the use of MALDI IMS to detect proteins from cardiac tissue is limited. This review discusses the most recent advances in protein imaging and demonstrates application to cardiac tissue, including the heart valve. Protein imaging by MALDI IMS allows multiplexed histological mapping of proteins and protein components that are inaccessible by antibodies and should be considered an important tool for basic and clinical cardiovascular research. This article is part of a Special Issue entitled: MALDI Imaging, edited by Dr. Corinna Henkel and Prof. Peter Hoffmann.

Abstract
Mechanical conditioning of engineered tissue constructs is widely recognized as one of the most relevant methods to enhance tissue accretion and microstructure, leading to improved mechanical behaviors. The understanding of the underlying mechanisms remains rather limited, restricting the development of in silico models of these phenomena, and the translation of engineered tissues into clinical application. In the present study, we examined the role of large strip-biaxial strains (up to 50%) on ECM synthesis by vascular smooth muscle cells (VSMCs) micro-integrated into electrospun polyester urethane urea (PEUU) constructs over the course of 3 weeks. Experimental results indicated that VSMC biosynthetic behavior was quite sensitive to tissue strain maximum level, and that collagen was the primary ECM component synthesized. Moreover, we found that while a 30% peak strain level achieved maximum ECM synthesis rate, further increases in strain level lead to a reduction in ECM biosynthesis. Subsequent mechanical analysis of the formed collagen fiber network was performed by removing the scaffold mechanical responses using a strain-energy based approach, showing that the denovo collagen also demonstrated mechanical behaviors substantially better than previously obtained with small strain training and comparable to mature collagenous tissues. We conclude that the application of large deformations can play a critical role not only in the quantity of ECM synthesis (i.e. the rate of mass production), but also on the modulation of the stiffness of the newly formed ECM constituents. The improved understanding of the process of growth and development of ECM in these mechano-sensitive cell-scaffold systems will lead to more rational design and manufacturing of engineered tissues operating under highly demanding mechanical environments.

Abstract
The social services, especially today, are intent on providing ghetto dwellers with adequate care. But this mission cannot be accomplished unless service workers are willing to enter ghetto areas and to incur risks to their physical safety. This paper describes some of the sociopsychological and structural influences which induced and later enabled a group of social workers to expose themselves to physical harm. On a more general level, it bears on the following question: how do organizations ensure that undesirable positions are filled?

Abstract
BACKGROUND Performance assessment in congenital heart surgery is challenging due to the wide heterogeneity of disease. We describe current case mix across centers, evaluate methodology inclusive of all cardiac operations versus the more homogeneous subset of Society of Thoracic Surgeons benchmark operations, and describe implications regarding performance assessment. METHODS Centers (n = 119) participating in the Society of Thoracic Surgeons Congenital Heart Surgery Database (2010 through 2014) were included. Index operation type and frequency across centers were described. Center performance (risk-adjusted operative mortality) was evaluated and classified when including the benchmark versus all eligible operations. RESULTS Overall, 207 types of operations were performed during the study period (112,140 total cases). Few operations were performed across all centers; only 25% were performed at least once by 75% or more of centers. There was 7.9-fold variation across centers in the proportion of total cases comprising high-complexity cases (STAT 5). In contrast, the benchmark operations made up 36% of cases, and all but 2 were performed by at least 90% of centers. When evaluating performance based on benchmark versus all operations, 15% of centers changed performance classification; 85% remained unchanged. Benchmark versus all operation methodology was associated with lower power, with 35% versus 78% of centers meeting sample size thresholds. CONCLUSIONS There is wide variation in congenital heart surgery case mix across centers. Metrics based on benchmark versus all operations are associated with strengths (less heterogeneity) and weaknesses (lower power), and lead to differing performance classification for some centers. These findings have implications for ongoing efforts to optimize performance assessment, including choice of target population and appropriate interpretation of reported metrics.

Abstract
The Society of Thoracic Surgeons Congenital Heart Surgery Database is the largest congenital and pediatric cardiac surgical clinical data registry in the world. It is the platform for all activities of The Society of Thoracic Surgeons related to the analysis of outcomes and the improvement of quality in this subspecialty. This article summarizes current aggregate national outcomes in congenital and pediatric cardiac surgery and reviews related activities in the areas of quality measurement, performance improvement, and transparency. The reported data about aggregate national outcomes are exemplified by an analysis of 10 benchmark operations performed from January 2011 to December 2014 and documenting overall discharge mortality (interquartile range among programs with more than 9 cases): off-bypass coarctation, 1.0% (0.0% to 0.9%); ventricular septal defect repair, 0.7% (0.0% to 1.1%); tetralogy of Fallot repair, 1.0% (0.0% to 1.7%); complete atrioventricular canal repair, 3.2% (0.0% to 6.5%); arterial switch operation, 2.7% (0.0% to 5.6%); arterial switch operation plus ventricular septal defect, 5.3% (0.0% to 6.7%); Glenn/hemiFontan, 2.1% (0.0% to 3.8%); Fontan operation, 1.4% (0.0% to 2.4%); truncus arteriosus repair, 9.6% (0.0 % to 11.8%); and Norwood procedure, 15.6% (10.0% to 21.4%).
