Abstract Batteries are often packed together to meet voltage and capability needs. However, due to variations in raw materials, different ages of equipment, and manual operation, there is inconsistency between batteries, which leads to reduced available capacity, variability of resistance, and premature failure. Therefore, it is crucial to pack similar batteries together. The conventional approach to screening batteries is based on their capacity, voltage and internal resistance, which disregards how batteries perform during manufacturing. In the battery discharge process, real time discharge voltage curves (DVCs) are collected as a set of unlabeled time series, which reflect how the battery voltage changes.… More >

Abstract Extracting nonlinear governing equations from noisy data is a central challenge in the analysis of complicated nonlinear behaviors. Despite researchers follow the sparse identification nonlinear dynamics algorithm (SINDy) rule to restore nonlinear equations, there also exist obstacles. One is the excessive dependence on empirical parameters, which increases the difficulty of data pre-processing. Another one is the coexistence of multiple coefficient vectors, which causes the optimal solution to be drowned in multiple solutions. The third one is the composition of basic function, which is exclusively applicable to specific equations. In this article, a local sparse screening identification algorithm (LSSI) is proposed… More >

Abstract Background: In asymptomatic children, screening echocardiography has been used to attempt to diagnose rheumatic heart disease (RHD) at an early stage (latent RHD). World Heart Federation guidelines have standardized categorization of “definite,” “borderline,” or no RHD by echo findings. The progression of RHD diagnosed through echo screening is not known. In 2014, we screened 1450 schoolchildren in Malawi.
Objective: Our objective was to evaluate 2‐year RHD evolution among those diag‐ nosed through screening.
Methods: Two‐year follow‐up echocardiograms of those diagnosed with latent RHD were read by a primary, secondary, then third reader if there was disagreement. Progression or regression of… More >

Abstract In the 2017, “Cairo Accord on Rheumatic Heart Disease—From Molecules to The Global Community” experts from endemic areas enumerated an approach to reduce the population burden of rheumatic heart disease. The 10 key recommendations in‐ clude immediate logistical objectives as well as domains for further study. Echocardiographic population screening programs were relegated to research alone. Given the large body of supporting data, relegating echo screening to an investiga‐ tional modality is an opportunity lost. More >

Abstract Objective: The aim is to present current clinical practice of thoracic aorta screening in a tertiary referral center. We identified how often imaging techniques were used for screening and established the value of transthoracic echocardiography (TTE) in com‐ parison with computed tomography (CT) to detect aortic dilation. We also investigated which additional abnormalities of the heart, aorta or smaller arteries were discovered.
Design: All patients ≥15 years who visited our tertiary center in 2012‐2016 for first thoracic aortic screening were retrospectively included. Diameters of the sinus of Valsalva (SoV) and maximum ascending aorta (AA) were compared between TTE and CT.… More >

Abstract Objective: Children with congenital heart disease (CHD) and adults with acquired heart disease are at an increased risk of neurocognitive impairment. The objective of this study was to determine the prevalence of self‐reported neurocognitive impair‐ ment and its risk factors in the adult congenital heart disease (ACHD) population.
Design: The Wisconsin Adult Congenital Heart Disease Program recently began screening ACHD patients to identify those with significant self‐perceived neurocog‐ nitive impairments. Screening consists of using a validated neuro‐oncology screening instrument that has been modified for the ACHD population. Patients who answer this survey in a predetermined fashion consistent with significant self‐perceived… More >

Abstract Background: Accurate prenatal diagnosis of congenital heart disease (CHD) allows for appropriate delivery and postnatal management. Geographic constraints limit access to fetal cardiology subspecialists. In our approach, general pediatric cardiologists are first line in regional prenatal cardiac screening. We aim to demonstrate the utility of this approach in diagnosing CHD requiring cardiac interventions within 30 days of life.
Methods: This is a retrospective review of fetal echocardiograms performed at Seattle Children’s Hospital regional cardiology sites (SCH-RC) from December 2008 to December 2015. Referrals to Seattle Children’s Hospital Prenatal Program (SCH-PNP) were evaluated for referral timing, indication, diagnostic accuracy, and postnatal… 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 Objective: The objective of this study was to analyze if the addition of simple cardiac scan in cases with increased nuchal translucency (NT) and/or abnormal ductus venosus (DV) blood flow, and/or tricuspid regurgitation (TCR) can improve detection of congenital heart defects (CHD) in chromosomally normal fetuses without non‐ cardiac defects at 11‐13 + 6 gestational weeks in a population of singleton pregnancies.
Methods: During the 10 years period, all singleton pregnancies at 11‐13 + 6 weeks were routinely scanned for NT, DV blood flow and TCR assessment and, if a sin‐ gle of these parameters was abnormal, simple cardiac scan… More >

Abstract Objective: As adults with congenital heart disease (CHD) grow older, preoperative screening for coronary artery disease (CAD) may be indicated prior to CHD surgery. Data regarding the indications for preoperative CAD screening in this population are limited. Current practice is to follow guidelines for patients with valvular heart dis‐ ease; however, the risk for CAD in certain congenital heart diagnoses may be higher than the general population. This study aimed to assess the results of preoperative CAD screening in patients prior to CHD surgery.
Design: Retrospective study.
Setting: Single tertiary center.
Patients: Patients ≥35 years that had CHD surgery from… More >
