Abstract Background: Much has been written about the loss to follow-up in the transition between pediatric and adult Congenital Heart Disease (CHD) care centers. Much less is understood about the loss to follow-up (LTF) after a successful transition. This is critical too, as patients lost to specialised care are more likely to experience morbidity and premature mortality. Aims: To understand the prevalence and reasons for loss to follow-up (LTF) at a large Australian Adult Congenital Heart Disease (ACHD) centre. Methods: Patients with moderate or highly complex CHD and gaps in care of >3 years (defined as LTF)… More >

Abstract Aiming at the drift problem that the tracking control of the actual load relative to the target load during the electromagnetic excitation biaxial fatigue test of wind turbine blades is easy to drift, a biaxial fatigue testing machine for electromagnetic excitation is designed, and the following strategy of the actual load and the target load is studied. A Fast Transversal Recursive Least Squares algorithm based on fuzzy logic (Fuzzy FTRLS) is proposed to develop a fatigue loading following dynamic strategy, which adjusts the forgetting factor in the algorithm through fuzzy logic to overcome the contradiction More >

Abstract Background: Limited data are available regarding intermediate and long-term outcomes of transcatheter closure (TCC) of coronary cameral fistulas (CCFs) in the pediatric patients. Methods: All pediatric patients diagnosed with CCFs who were scheduled to undergo TCC between 2005 and 2019 were retrospectively enrolled in the study. Results: A total of 66 patients (median age: 3.93 years, median weight: 15 kg) underwent attempted TCC of CCFs. Immediate successful device implantation was achieved in 62 patients, and immediate complete occlusion was achieved in 44 patients (44/62%, 71.0%). The closure procedure was waived in 2 patients due to anatomical factors.… More >

Abstract Background: The Venus-P valve was the first self-expanding valve used world-wide for transcatheter pulmonary valve replacement (TPVR) in patients with severe pulmonary regurgitation (PR). We intended to report the extended follow-up results from the prospective trial (No. NCT02590679). Methods: A total of 38 patients with severe PR (mean age 24.2 ± 13.2) were included. Follow-up data were obtained after implanted at 1, 6, and 12 months and yearly after. The frame geometry was assessed on post-implant computer tomography (CT) scanning by calculating the non-circularity [circularity ratio (minimum diameter/maximum diameter) < 0.9] and under-expansion [expansion ratio (derived external valve… More > Graphic Abstract

Abstract Objective: This study was designed to determine the long-term safety and efficacy of using the Amplatzer Duct Occluder II (ADO II) for the closure of various ventricular septal defects (VSDs). Methods: From January 2011 to December 2019, selected VSD patients were treated through transcatheter intervention using ADO II occluders. The closure results and complications from 188 patients, involving 167 perimembranous ventricular septal defects (pmVSDs), 9 intracristal VSDs, 11 post surgery residual shunts and 1 post closure residual shunt with the mean outlet diameter3.1 ± 0.8 mm under angiography, were enrolled in this study. Results: The success rate… More >

Abstract Background: Thromboembolic events are a cause of significant morbidity and mortality in the Fontan population. We previously reported on coagulation profile changes in a cohort of patients with hypoplastic left heart syndrome (HLHS) from Stage I through Fontan completion. In this report, we examine their clinical status, anticoagulation and incidence of thromboembolic events up to 20 years post Fontan. Methods: A retrospective chart review was conducted for twenty (20) surviving patients, from 1998 through December 2020. Patients who underwent orthotopic heart transplantation (OTx) were followed until their transplant. Patients who were found in the original study… More >

Abstract Background: In recent decades, aortic stenting has become a promising alternative to surgery for both native aortic coarctation and re-stenosis in children and adults. However, comparative long-term outcomes have poorly been investigated. Methods: We included 212 patients with previous aortic repair (19 ± 8.7 years) divided into 3 groups: 139 with single-time surgical repair (CoA-S group); 18 with single-time percutaneous stenting (CoA-PS group); and 55 hybrid patients with multiple aortic procedures because of re-coarctation occurrence (CoA-H group). All patients underwent 24-hour ambulatory blood pressure monitoring and trans-thoracic echocardiography. Results: After a median follow-up of 17 years after… More >

Abstract Introduction: Due to the low prevalence and wide variation of severity of Ebstein’s Anomaly (EA), long-term follow-up data are scarce. The aim was to evaluate the long-term outcome of an adult population with EA. Methods: Retrospective analysis of EA adults followed in the past 42 years in a tertiary congenital heart disease outpatient clinic. Predictors of complications and mortality were assessed. Results: We studied 53 patients: 53% females, mean age 46 ± 19 years, 36% cyanotic, 55% diagnosed at adult age. Tricuspid regurgitation was moderate or severe in 33% and 46%, respectively, and during follow-up (mean… More >

Abstract Atherosclerotic plaque progression is generally considered to be closely associated with morphological and mechanical factors. Plaque morphological information on intravascular ultrasound (IVUS) and optical coherence tomography (OCT) images could complement each other and provide for more accurate plaque morphology. Fluid-structure interaction (FSI) models combining IVUS and OCT were constructed to obtain accurate plaque stress/strain and flow shear stress data for analysis. Accuracy and completeness of imaging and advanced modeling lead to accurate plaque progression predictions.
In vivo IVUS and OCT coronary plaque data at baseline and follow-up were acquired from left circumflex coronary and right coronary… More >

Abstract Objective: We describe the long-term follow-up of a child with recurrent hemoptysis due to severe pulmonary vein stenosis decompressing via collaterals to esophageal varices.
Design: Case report
Setting: Tertiary children’s hospital
Patient: Single child through ages 2- to 11-year old
Interventions: The child underwent cutting balloon angioplasty, bare metal stenting, and implantation of a PTFE-covered stent, all of which failed rapidly. Only after placement of a paclitaxel drug eluting stent did he have prolonged relief from hemoptysis and long-term patency of the treated vein. The stents were serially dilated to keep up with somatic growth of the child, eventually culminating More >
