Lymphatic Disorder Management in Pediatric Patients With Congenital Heart Disease in European Pediatric Cardiology Centers: Current Status, Disparities, and Future Considerations.

Background: Lymphatic disorders such as protein-losing enteropathy, plastic bronchitis, and chylothorax are important complications of the Fontan circulation and ultimately result in an increased risk of early death. Several European centers are now performing lymphatic procedures. The aim of this study is to map the extent of these lymphatic disorders and treatments provided across European pediatric cardiology centers.

Organisation of paediatric echocardiography laboratories and governance of echocardiography services and training in Europe: current status, disparities, and potential solutions. A survey from the Association for European Paediatric and Congenital Cardiology (AEPC) imaging working group.

Background: There is limited data on the organisation of paediatric echocardiography laboratories in Europe.

Methods: A structured and approved questionnaire was circulated across all 95 Association for European Paediatric and Congenital Cardiology affiliated centres. The aims were to evaluate: (1) facilities in paediatric echocardiography laboratories across Europe, (2) accredited laboratories, (3) medical/paramedical staff employed, (4) time for echocardiographic studies and reporting, and (5) training, teaching, quality improvement, and research programs.

Phononic Crystal Made of Silicon Ridges on a Membrane for Liquid Sensing.

We propose the design of a phononic crystal to sense the acoustic properties of a liquid that is constituted by an array of silicon ridges on a membrane. In contrast to other concepts, the ridges are immersed in the liquid. The introduction of a suitable cavity in the periodic array gives rise to a confined defect mode with high localization in the cavity region and strong solid-liquid interaction, which make it sensitive to the acoustic properties of the liquid.

Emerging topics in nanophononics and elastic, acoustic, and mechanical metamaterials: an overview.

This broad review summarizes recent advances and "hot" research topics in nanophononics and elastic, acoustic, and mechanical metamaterials based on results presented by the authors at the EUROMECH 610 Colloquium held on April 25-27, 2022 in Benicássim, Spain. The key goal of the colloquium was to highlight important developments in these areas, particularly new results that emerged during the last two years. This work thus presents a "snapshot" of the state-of-the-art of different nanophononics- and metamaterial-related topics rather than a historical view on these subjects, in contrast to a conventional review article.

Enhanced Echocardiography Imaging in Reoperation for Complex Congenital Heart Disease in a Child.

• Evaluation of the mechanism of MR is essential for appropriate repair. • 2D and 3D TEE are the gold standard for presurgical MV repair in children. • Enhanced echo imaging improves benefits in complex congenital heart disease.

Physics of surface vibrational resonances: pillared phononic crystals, metamaterials, and metasurfaces.

The introduction of engineered resonance phenomena on surfaces has opened a new frontier in surface science and technology. Pillared phononic crystals, metamaterials, and metasurfaces are an emerging class of artificial structured media, featuring surfaces that consist of pillars-or branching substructures-standing on a plate or a substrate. A pillared phononic crystal exhibits Bragg band gaps, while a pillared metamaterial may feature both Bragg band gaps and local resonance hybridization band gaps.

Imaging the adult with simple shunt lesions: position paper from the EACVI and the ESC WG on ACHD. Endorsed by AEPC (Association for European Paediatric and Congenital Cardiology).

In 2018, the position paper 'Imaging the adult with congenital heart disease: a multimodality imaging approach' was published. The paper highlights, in the first part, the different imaging modalities applied in adult congenital heart disease patients. In the second part, these modalities are discussed more detailed for moderate to complex anatomical defects.

Cone reconstruction for Ebstein anomaly: Late biventricular function and possible remodeling.

Objectives: To evaluate late-term tricuspid valve competence and biventricular function following cone reconstruction for Ebstein anomaly, and to explore biventricular remodeling.

Methods: Consecutive adult and pediatric patients who underwent cone reconstruction from 2009 to 2019 were reviewed for inclusion in this retrospective cardiac magnetic resonance imaging study. Tricuspid valve competence was assessed with tricuspid regurgitation fraction.

Elastic stubbed metamaterial plate with torsional resonances.

We report on a new mechanism involving the torsional resonance of stubs to achieve the negative effective shear modulus of an elastic metamaterial plate. Combined with a mechanism to create a negative mass density, we develop a general method to set up and enlarge a shear-horizontal-polarized double-negative branch in the elastic metamaterial plate with stubs on both sides. We explore the capabilities of this structure for polarization filtering, mode conversion and abnormal refraction.

The utility of aortic valve leaflet reconstruction techniques in children and young adults.

Objectives: The treatment of aortic valve disease in children and adolescents requires an individualized approach to provide a long-term solution with optimal hemodynamic profile. The role of aortic leaflet reconstruction techniques is evolving.

Methods: We retrospectively reviewed the charts of 58 patients who underwent aortic valve tricuspidalization either by an Ozaki procedure (neo-tricuspidalization) or single leaflet reconstruction between 2015 and 2019.

Predictors of intention translation in flexible sigmoidoscopy screening for colorectal cancer.

Objective: This prospective study aimed to identify predictors of intention and subsequent attendance of flexible sigmoidoscopy screening using constructs derived from the Health Belief Model (HBM).

Method: A total of 4,330 people aged 54 years and registered at 1 of 83 participating English general practices were sent a preinvitation questionnaire to assess sociodemographics, HBM variables including perceived benefits, barriers, seriousness, health motivation, and external cues to action as well a range of other constructs and personal characteristics known to relate to cancer screening.

Results: Of the 1,578 respondents (36.

A simple measure of the extent of Ebstein valve rotation with cardiovascular magnetic resonance gives a practical guide to feasibility of surgical cone reconstruction.

Background: Once surgical management is indicated, variation of Ebstein valve morphology affects surgical strategy. This study explored practical, easily measureable, cardiovascular magnetic resonance (CMR)-derived attributes that may contribute to the complexity and risk of cone reconstruction.

Methods: A retrospective assessment was performed of Ebstein anomaly patients older than 12 years age, with pre-operative CMR, undergoing cone surgical reconstruction by one surgeon.

Barriers to bowel scope (flexible sigmoidoscopy) screening: a comparison of non-responders, active decliners and non-attenders.

Background: Participation in bowel scope screening (BSS) is low (43%), limiting its potential to reduce colorectal cancer (CRC) incidence and mortality. This study aimed to quantify the prevalence of barriers to BSS and examine the extent to which these barriers differed according to non-participant profiles: non-responders to the BSS invitation, active decliners of the invitation, and non-attenders of confirmed appointments.

Methods: Individuals invited for BSS between March 2013 and December 2015, across 28 General Practices in England, were sent a questionnaire.

Imaging the adult with congenital heart disease: a multimodality imaging approach-position paper from the EACVI.

Advances in the diagnosis and management of congenital heart disease have led to a marked improvement in the survival of adult with congenital heart disease (ACHD) patients. However, ACHD patients are a heterogeneous population, with a large spectrum of anatomic substrates even within specific lesions. In addition, the nature of previous surgery and other intervention is highly variable rendering each patient unique and residual anatomic and haemodynamic abnormalities are very common.

Infective Endocarditis Associated With Varicella Zoster Virus Following Aortic Valve Repair.

We describe the management and clinical course of two children with congenital bicuspid aortic valve. Neo-tricuspidization was performed in one case using CardioCel leaflets and two cusps were formed from CardioCel and grafted alongside one native leaflet in the other. Both patients developed bacterial endocarditis associated with varicella zoster virus infection and required a second surgical procedure.

Symptomatic partial and transitional atrioventricular septal defect repaired in infancy.

Objectives: Infants with symptomatic partial and transitional atrioventricular septal defect undergoing early surgical repair are thought to be at greater risk. However, the outcome and risk profile of this cohort of patients are poorly defined. The aim of this study was to investigate the outcome of symptomatic infants undergoing early repair and to identify risk factors which may predict mortality and reoperation.

Ultra-low and ultra-broad-band nonlinear acoustic metamaterials.

Linear acoustic metamaterials (LAMs) are widely used to manipulate sound; however, it is challenging to obtain bandgaps with a generalized width (ratio of the bandgap width to its start frequency) >1 through linear mechanisms. Here we adopt both theoretical and experimental approaches to describe the nonlinear chaotic mechanism in both one-dimensional (1D) and two-dimensional (2D) nonlinear acoustic metamaterials (NAMs). This mechanism enables NAMs to reduce wave transmissions by as much as 20-40 dB in an ultra-low and ultra-broad band that consists of bandgaps and chaotic bands.

Contemporary cardiac surgery for adults with congenital heart disease.

Objective: Advances in early management of congenital heart disease (CHD) have led to an exponential growth in adults with CHD (ACHD). Many of these patients require cardiac surgery. This study sought to examine outcome and its predictors for ACHD cardiac surgery.

Using a hypothetical scenario to assess public preferences for colorectal surveillance following screening-detected, intermediate-risk adenomas: annual home-based stool test vs. triennial colonoscopy.

Background: To assess public preferences for colorectal cancer (CRC) surveillance tests for intermediate-risk adenomas, using a hypothetical scenario.

Methods: Adults aged 45-54 years without CRC were identified from three General Practices in England (two in Cumbria, one in London). A postal survey was carried out during a separate study on preferences for different first-line CRC screening modalities (non- or full-laxative computed tomographic colonography, flexible sigmoidoscopy, or colonoscopy).
