Abstract Generative adversarial network (GAN) is one of the most promising methods for unsupervised learning in recent years. GAN works via adversarial training concept and has shown excellent performance in the fields image synthesis, image super-resolution, video generation, image translation, etc. Compared with classical algorithms, quantum algorithms have their unique advantages in dealing with complex tasks, quantum machine learning (QML) is one of the most promising quantum algorithms with the rapid development of quantum technology. Specifically, Quantum generative adversarial network (QGAN) has shown the potential exponential quantum speedups in terms of performance. Meanwhile, QGAN also exhibits some problems, such as barren… More >

Abstract MEMS accelerometers are widely used in various fields due to their small size and low cost, and have good application prospects. However, the low accuracy limits its range of applications. To ensure data accuracy and safety we need to calibrate MEMS accelerometers. Many authors have improved accelerometer accuracy by calculating calibration parameters, and a large number of published calibration methods have been confusing. In this context, this paper introduces these techniques and methods, analyzes and summarizes the main error models and calibration procedures, and provides useful suggestions. Finally, the content of the accelerometer calibration method needs to be overcome. More >

Abstract Background: Splenic dysfunction is common in heterotaxy syndrome, and increases the risk of bacteremia and bacteremia related mortality. Despite the risks associated with bacteremia in this setting, best practice guidelines for management of infectious concerns are lacking. We conducted a survey of pediatric cardiologists to characterize practice regarding the diagnosis of splenic dysfunction, approach to antibiotic prophylaxis, and management of possible bacterial infection.
Methods: A 22-item web-based survey was distributed via email to pediatric cardiologists in North America.
Results: We received 230 responses from 63 centers, for a response rate of 22%. The majority (83%) always obtain abdominal ultrasound to… More >

Abstract Background: The treatment of children with cardiac disease is one of the most prevalent and costly pediatric inpatient conditions. The design of inpatient medical services for children admitted to and discharged from noncritical cardiology care units, however, is undefined. North American Pediatric Cardiology Programs were surveyed to define noncritical cardiac care unit models in current practice.
Method: An online survey that explored institutional and functional domains for noncritical cardiac care unit was crafted. All questions were multi-choice with comment boxes for further explanation. The survey was distributed by email four times over a 5-month period.
Results: Most programs (n =… More >

Abstract Objectives: Siblings of children with chronic medical conditions endorse a lower quality of life compared to age-matched peers. Caregiver and sibling-self report of adjustment are often discordant. Congenital heart disease significantly affects family life. To date, there have been no studies addressing the functioning of siblings of children with hypoplastic left heart syndrome, one of the most severe forms of congenital heart disease. The goal of this study was to assess the impact of hypoplastic left heart syndrome on sibling’s quality of life as well as the caregiver’s perception of this effect.
Study Design: Cross-sectional study using a web-based survey… More >

Abstract Objective: Although pediatrician-reported relevance of Canadian cardiology-specific objectives has been studied, similar data are not available for the 2016 American Board of Pediatrics (ABP) cardiology-specific objectives. This study asked Kentucky trainees, pediatricians, and pediatric cardiologists to identify “most important” content within these objectives.
Design, Methods, Outcome Measures: This cross-sectional study used an original, online survey instrument based on the 2016 ABP cardiology-specific objectives. We collected quantitative data (numerical indications of importance) and qualitative data (open-ended replies regarding missing content and difficulty in teaching and learning). Respondents indicated the top two choices of most important items within eight content areas. Descriptive… More >

Abstract Introduction: Surveillance and management guidelines for Fontan patients are lacking due to the paucity of evidence in the literature of screening efficacy on outcome measures.
Methods: The Fontan Working Group within the New England Congenital Cardiology Association designed an electronic survey to assess surveillance practices for pa‐ tients with Fontan procedures among New England congenital cardiologists and to explore variability in screening low‐risk vs high‐risk Fontan patients across regional programs.
Results: Fifty‐six cardiologists representing 12 regional programs responded to the survey, comprising ~40% of the total New England congenital cardiac physicians. The majority of desired testing and consultation was available… More >

Abstract Background: Physician burnout has many undesirable consequences, including nega‐ tive impact on patient care delivery and physician career satisfaction. Electronic health records (EHRs) may exacerbate burnout by increasing physician workload.
Objective: To determine burnout in adult congenital heart disease (ACHD) specialists by assessing stress associated with EHRs.
Design: Electronic survey study of ACHD providers.
Setting: Canada and United States.
Participants: Three hundred eighty‐three ACHD specialists listed on the Adult Congenital Heart Association directory between February and April 2017.
Outcome Measures: Burnout was measured using the Maslach Burnout Inventory (MBI) to understand factors contributing to work life and EHR satisfaction. Chi‐… More >

Abstract Background: The Pediatric Acute Care Cardiology Collaborative (PAC3) was estab‐ lished in 2014 to improve the quality, value, and experience of hospital‐based cardiac acute care outside of the intensive care unit. An initial PAC3 project was a compre‐ hensive survey to understand unit structure, practices, and resource utilization across the collaborative. This report aims to describe the previously unknown degree of practice variation across member institutions.
Methods: A 126‐stem question survey was developed with a total of 412 possible response fields across nine domains including demographics, staffing, available re‐ sources and therapies, and standard care practices. Five supplemental questions ad‐… More >

Abstract Background: Patent ductus arteriosus (PDA) is highly prevalent in extremely low birth weight (ELBW), preterm infants. There are diverse management approaches for the PDA in ELBW infants. The objectives of this research were to identify current PDA management practices among cardiologists and neonatologists in the United States, describe any significant differences in management, and describe areas where practices align.
Methods: A survey of 10 questions based on the management of PDA in ELBW infants was conducted among 100 prominent neonatologists from 74 centers and 103 prominent cardiologists from 75 centers. Among the cardiologists, approximately 50% were interventionists who perform transcatheter… More >
