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… More >

Abstract Objective: Outcomes after surgical repair of complete atrioventricular septal defect (cAVSD) have improved. With advancing age, the risk of development of dysrhythmias may increase. The aims of this study were to (1) examine development of sinus node dysfunction (SND), atrial and ventricular tachyarrhythmias, and (2) study progression of atrioventricular conduction abnormalities in young adult patients with repaired cAVSD.
Study design: In this retrospective multicenter study, 74 patients (68% female) with a cAVSD repaired in childhood were included. Patients’ medical files were evaluated for occurrence of SND, atrioventricular conduction block (AVB), atrial and ventricular tachyarrhythmias.
Results: Median age at… More >

Abstract Cardiovascular diseases are the leading cause of human deaths worldwide. Traditional diagnostic tools of cardiovascular diseases are either based on 2D static medical images, or invasive, bringing troubles to both patients and doctors. Our team is committed to the development of image-based non-invasive diagnostic system for cardiovascular diseases. We have made progress mainly in the following areas: 1) 4D flow technology for heart and large blood vessels. According to MRI 4D Flow data, three-dimensional velocity fields within blood vessels were constructed. Divergence-fee smoothing (DFS) was proposed to eliminate the high frequency noise in the hemodynamic… More >

Abstract Medical imaging and image-based modeling have made considerable progress in recent years in cardiovascular research, such as identifying atherosclerotic plaque morphological and mechanical risk factors which may be used in developing improved patient screening strategies, and performing virtual heart surgery seeking optimal surgical procedures for best post-surgical outcome. We will report recent progress in using multi-modality image-based models to predict vulnerable plaque progression and vulnerability change. In particular, we will report our recent results using IVUS+OCT data to obtain more accurate stress/strain calculations. Inflammation and cap erosion will affect cap material properties. If OCT image… More >

Abstract Cardiovascular disease remains as the leading cause of death worldwide, and the technologies developed by different groups need to be communicated and shared with all related research communities for a boarder implementation. Challenges in imaging technology, mathematical modelling, material description, mechanical representation, disease progression, prediction methods, and final transition to clinical applications are calling for collaborative effort of the entire research community to act together and bring research effort closer to actual clinical applications. Researchers from different disciplines need to reach out to share their expertise, as well as to listen to other people to More >

Abstract A new paradigm of VANET has emerged in recent years: Internet of Vehicles (IoV). These networks are formed on the roads and streets between travellers who have relationships, interactions and common social interests. Users of these networks exchange information of common interest, for example, traffic jams and dangers on the way. They can also exchange files such as multimedia files. IoV is considered as part of the Internet of Things (IoT) where objects are vehicles, which can create a multitude of services dedicated to the intelligent transportation system. The interest is to permit to all… More >

Abstract The communication reliability and system capacity are two of the key performance indicators for Internet of Vehicles (IoV). Existing studies have proposed a variety of technologies to improve reliability and other performance, such as channel selection and power allocation in Vehicle-to-Infrastructure (V2I). However, these researches are mostly applied in a single roadside unit (RSU) scenario without considering inter-cell interference (ICI) of multi-RSUs. In this paper, considering the distribution characteristics of multi-RSUs deployment and corresponding ICI, we propose a reliable uplink transmission scheme to maximize the total capacity and decrease the interference of multi-RSUs (mRSU-DI) in More >

Abstract Background: Congenital heart defects affect nearly 1% of all children born per year in the United States, and complete atrioventricular canal (CAVC) accounts for 2%‐9%. While several patch materials have been used for septal defect closure during CAVC repair, clear superiority of one material over another has yet to be established.
Methods: A retrospective review of clinical outcomes following CAVC repair at Morgan Stanley Children’s Hospital/Columbia University was performed on opera‐ tions conducted from March 2010 to September 2017. Univariate and Kaplan‐Meir survival analyses were utilized to evaluate primary outcomes of interest following CAVC repair in the… More >

Abstract Introduction: Hyperuricemia has been associated with cardiovascular risk factors but it remains controversial if uric acid is an independent predictor of cardiac mortality.
Methods: A total of 503 CHD patients (457 nonhypoxemic and 46 hypoxemic) and 772 control patients fulfilled inclusion criteria. Demographic, clinical, and analytical data [serum uric acid and 24h urine uric acid levels, N‐terminal pro‐B‐type natriuretic peptide (NT‐pro‐BNP), and C‐reactive‐protein (CRP) concentrations] were studied. Survivals curves to determine cardiac death and arterial thrombosis in CHD patients were also examined.
Results: Noncyanotic and cyanotic CHD patients had significant higher serum uric acid concentration (5.2 ± 1.5 vs 4.9 ± 1.3mg/dL,… More >

Abstract Objective: Individuals with congenital heart disease (CHD) may be at higher risk of acquired cardiovascular disease than the general population due to their underlying physiology and/or surgical sequelae. We sought to assess the prevalence of cardiovascular disease risk factors in youth and adults with CHD.
Methods: We assessed cardiovascular health as per the Cardiovascular Health in Ambulatory Care Research Team (CANHEART) health index in patients with CHD aged 15+ years who attended cardiology outpatient clinics. Participants self-reported smoking behavior, fruit and vegetable consumption, physical activity, and whether they had diabetes and hypertension. Individual health indices were categorized… More >
