    Congenital Heart Disease, Vol.16, No.3, pp. 245-254, 2021, DOI:10.32604/CHD.2021.014881

    Abstract Background: Never had literatures characterized the relationship between the property of major aortopulmonary collateral arteries (MAPCAs) and outcomes of selective unifocalization of pulmonary atresia with ventricular septal defects and MAPCAs. Methods: This is a case-series study. Thirteen patients were included. Angiography-based assessment was conducted to determine whether collateral arteries should be unifocalized or treated with intraoperative ligature. Specimens were collected and stained by HE and ET+VG. Results: Twelve patients underwent one-stage unifocalization at a median age of 37 months (range: 6–228 months) and a median weight of 14.0 kg (range: 5.0–49.0 kg), which produced a favorable right ventricle to aortic… More >

    Congenital Heart Disease, Vol.16, No.3, pp. 255-267, 2021, DOI:10.32604/CHD.2021.014628

    Abstract Background: Pediatric cardiology patients often experience decreased quality of life (QoL) and higher rates of mental illness, particularly with severe disease, but the relationship between them and comparisons across diagnostic groups are limited. This mixed-methods cross-sectional study assessed the association between QoL anxiety and behavior problems among children with structural heart disease, arrhythmia, or other cardiac diagnoses. Methods: Children (6–14 years, n = 76, 50% female) and their parents completed measures of QoL (PedsQL), behavior (BASC-2, subset of 19 children) and anxiety (MASC-2, children 8+ years). Pearson correlations/regression models examined associations between QoL, behavior and anxiety, controlling for age, sex,… More >

    R. Allen Ligon1,*, Larry A. Latson1, Mark M. Ruzmetov2, Kak-Chen Chan1, Todd Roth1, Immanuel I. Turner2, Frank G. Scholl2, Steve Bibevski2

    Congenital Heart Disease, Vol.16, No.3, pp. 285-297, 2021, DOI:10.32604/CHD.2021.014373

    Abstract Background: Pulmonary valve replacement (PVR) can be accomplished via surgical, transcatheter, or hybrid approaches. There are inherent advantages to transcatheter PVR and hybrid PVR without cardiopulmonary bypass. We review the methods and results of a standardized institutional approach to PVR. Methods: Retrospective review of all PVR cases between February 2017 and February 2020. Hybrid PVR entailed off-pump RVOT plication with percutaneous transcatheter PVR. Results: Primary transcatheter PVR was attempted in 37, hybrid PVR was performed in 11, and on-pump surgical PVR was performed in 9. Median age at PVR was 27 years (6–65). Primary transcatheter PVR was successful in 35/37… More >

    Abdul-Wahid A. Saif1, Mohammad Ataur-Rahman1, Sami Elferik1, Muhammad F. Mysorewala1, Mujahed Al-Dhaifallah1,*, Fouad Yacef2

    Intelligent Automation & Soft Computing, Vol.27, No.3, pp. 817-834, 2021, DOI:10.32604/iasc.2021.015932

    Abstract In this paper, the formation control problem of a group of unmanned air vehicle (UAV) quadrotors is solved using the Takagi–Sugeno (T–S) multi-model approach to linearize the nonlinear model of UAVs. The nonlinear model sof the quadrotor is linearized first around a set of operating points using Taylor series to get a set of local models. Our approach’s novelty is in considering the difference between the nonlinear model and the linearized ones as disturbance. Then, these linear models are interpolated using the fuzzy T–S approach to approximate the entire nonlinear model. Comparison of the nonlinear and the T–S model shows… More >
