Abstract Objective: Three scores have been proposed to stratify the risk of mortality for each cardiac surgical procedure: The RACHS‐1, the Aristotle Basic Complexity (ABC), and the STS‐EACTS complexity scoring model. The aim was to compare the ability to predict mortality and morbidity of the three scores applied to a specific population.
Design: Retrospective, descriptive study.
Setting: Pediatric and neonatal intensive care units in a referral hospital.
Patients: Children under 18 years admitted to the intensive care unit after surgery.
Interventions: None.
Outcome measures: Demographic, clinical, and surgical data were assessed. Morbidity was considered as prolonged length of stay (LOS >… More >

Abstract Background: Tube feedings are often needed to achieve the growth and nutrition goals associated with decreased morbidity and mortality in patients with single ventricle anat‐ omy. Variability in feeding method through the interstage period has been previously described, however, comparable information following stage 2 palliation is lacking.
Objectives: To identify types of feeding methods following stage 2 palliation and their influence on length of stay.
Design: Secondary analysis of the National Pediatric Cardiology Quality Improvement Collaborative registry was performed on 932 patients. Demographic data, medical characteristics, postoperative complications, type of feeding method, and length of stay for stage 2 palliation… 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 Objective: The bicuspid aortic valve (BAV) is the most common congenital heart dis‐ ease. The process of aortic dilatation is not completely clear in patients with the BAV. Apelin is a peptide found at high levels in vascular endothelial cells which has a role in vascular regulation and cardiovascular function. The aim of this study was to de‐ termine the relationship between serum apelin levels and ascending aortic dilatation in adult patients with BAV.
Design: This cross‐sectional study included 62 patients with isolated BAV and to an age, gender, and body mass index‐matched control group of 58 healthy volunteers with… More >

Abstract Aim: The Fontan circulation is highly dependent on ventilation, improving pulmonary blood flow and cardiac output. A reduced ventilatory function is reported in these patients. The extent of this impairment and its relation to exercise capacity and qual‐ ity of life is unknown and objective of this study.
Methods: This multicenter retrospective/cross‐sectional study included 232 patients (140 females, age 25.6 ± 10.8 years) after Fontan palliation (19.8% atrioventricular connection; 20.3% atriopulmonary connection; 59.9% total cavopulmonary connec‐ tion). Resting spirometry, cardiopulmonary exercise tests, and quality‐of‐life assess‐ ment (SF‐36 questionnaire) were performed between 2003 and 2015.
Results: Overall, mean forced expiratory volume… More >

Abstract Background: In this study, we compared our experience about early and midterm follow‐up outcomes for right anterolateral minithoracotomy (RAMT) vs full sternot‐ omy (FS) in surgical aortic valve replacement (AVR) among adolescents with bicuspid aortic valve (BAV).
Methods: Patients were retrospectively enrolled from January 2008 to December 2017. Inclusion criteria were patients with BAV who had to undergo to AVR. They were divided in two groups: RAMT and FS. The choice of RAMT was based on indi‐ vidual surgeon’s preferences or when expressly requested by patient that was in‐ formed of nonconventional approach.
Results: We enrolled 61 patients, 23 in… More >

Abstract Objective: When imaging the lower airway by MRI, the traditional technique turbo spin echo (TSE) results in high quality 2D images, however planning and acquisition times are lengthy. An alternative, delayed volume interpolated breath-holds examination (VIBE), is a 3D gradient echo technique that produces high spatial resolution imaging of the airway in one breath-hold. The objective of this study is to retrospectively evaluate the accuracy of lower airway measurements obtained by delayed VIBE when compared to TSE.
Design: Patients with congenital heart disease who underwent a cardiac MRI (CMR) that included a delayed VIBE sequence from 5/2008 to 9/2013 were… More >

Abstract Objectives. There is a paucity of data about mixed aortic valve disease (MAVD) in patients with bicuspid/unicuspid aortic valve (BAV). This study sought to describe the outcomes of patients with moderate/severe MAVD.
Methods. We queried our database for patients with BAV and moderate/severe MAVD seen between 1994 and 2013. We excluded patients with baseline New York Heart Association (NYHA) III/IV symptoms, left ventricular ejection fraction <50%, aortic dimension >50 mm, and significant disease of other valves. The purpose of the study was to determine the freedom from NYHA III/IV symptoms and aortic valve replacement (AVR).
Results. We identified 138 patients… More >

Abstract The human respiratory system consists of the upper and the lower respiratory tracts. Anatomically, the lower respiratory tract consists of the trachea, bronchi, bronchioles (terminal bronchioles and respiratory bronchioles), alveolar duct, alveolar duct sacs, and alveoli. Alveoli are composed of two epithelial cell types, cuboidal alveolar type 2 (AT2) cells that secrete surfactant to prevent alveolar collapse and function as stem cells to regenerate alveolar type 1 (AT1) cells during damage repair, and squamous AT1 cells that cover most of the surface area of the alveoli and mediate gas exchange. Previous studies mainly focused on AT2 cells; this review summarizes… More >

Abstract Motion artifacts of in vivo imaging, due to rapid respiration rate and respiration displacements of the mice while free-breathing, is a major challenge in micro computed tomography(micro-CT). The respiratory gating is often served for either projective images acquisition or per projection qualification, so as to eliminate the artifacts brought by in vivo motion. In this paper, we propose a novel respiratory gating method, which firstly divides one rotation cycle into a number of segments, and extracts the respiratory signal from the projective image series of current segment by the value of the epipolar consistency conditions (ECC), then in terms of… More >
