Abstract Background: We report a multi‐institutional experience with intravascular stenting (IS) for treatment of coarctation the aorta. Methods and Results: Data was collected retrospectively by review medical records from 17 institutions. The data broken down to prior 2002 after further analysis. A total 565 procedures were performed median age 15 years (mean = 18.1 years). Successful reduction in post stent gradient (<20 mm Hg) or increase descending aorta (DAo) ratio >0.8 achieved...
We report a multiinstitutional study on intermediate-term outcome of intravascular stenting for treatment coarctation the aorta using integrated arch imaging (IAI) techniques.Medical records 578 patients from 17 institutions were reviewed. A total 588 procedures performed between May 1989 and Aug 2005. About 27% (160/588) followed up by further IAI their (MRI/CT/repeat cardiac catheterization) after initial stent procedures. Abnormal studies included: presence dissection or aneurysm...
The hybrid magnetic resonance (MR)/X-ray suite (XMR) is a recently introduced imaging solution that provides new possibilities for guidance of cardiovascular catheterization procedures. We have previously described and validated technique based on optical tracking to register MR X-ray images obtained from the sliding table XMR configuration. aim our recent work was extend by providing an improved calibration stage, real-time during procedures, further off-line analysis mapping cardiac...
Abstract Introduction: Since the 1980s, stent implantation has evolved as an important therapeutic strategy for coarctation of aorta. However, available data is frequently flawed by short follow‐up, lack adequate follow‐up imaging, and retrospective nature collection. Methods : Data was prospectively collected using a multicenter registry congenital cardiovascular interventional study consortium (CCISC). Between 2000 2009, 302 patients from 34 centers with median weight 58 kg underwent...
Paravalvular leak (PVL) occurs in 5% to 17% of patients following surgical valve replacement. Percutaneous device closure represents an alternative repeat surgery.All UK and Ireland centers undertaking percutaneous PVL submitted data the Registry. Data were analyzed for association with death major adverse cardiovascular events (MACE) at follow-up.Three hundred eight procedures attempted 259 20 (2004-2015). Patient age was 67±13 years; 28% female. The main indications heart failure (80%)...
Covered stent correction of sinus venosus ASDs (SVASD) is a relatively new technique. Challenges include anchoring sufficiently long in nonstenotic superior vena cava (SVC) and expanding the at wider SVC-RA junction without obstructing anomalous right upper pulmonary vein (RUPV). The 10-zig covered Cheatham-platinum (CCP) has advantage being available lengths 5-11 cm dilatable to 34 mm diameter.An international registry reviewed outcomes CCP stents 75 patients aged 11.4-75.9 years (median...
To determine the early results of balloon expandable stent implantation for aortic coarctation or recoarctation.Prospective observational study.Two paediatric cardiology tertiary referral centres.17 patients, median age 17 years (range 4.4 to 45) and weight 61 kg (17 92). Six had native 11 recoarctation; 14 upper limb systolic hypertension. Of those with recoarctation, eight at least one previous dilatation attempt two these patients also further surgical interventions.Balloon Palmaz iliac...
We sought to develop a scoring system that predicts the risk of serious adverse events (SAE's) for individual pediatric patients undergoing cardiac catheterization procedures.Systematic assessment SAE in can be challenging view wide variation procedure and patient complexity as well rapidly evolving technology.A 10 component was originally developed based on expert consensus review existing literature. Data from an international multi-institutional registry (CCISC) between 2008 2013 were...
Objective To compare patient-reported, health-related quality of life (QoL) for children with serious congenital heart defects (CHDs) and unaffected classmates to investigate the demographic clinical factors influencing QoL. Design Retrospective cohort study. Setting UK National Health Service. Patients UK-wide CHDs aged 10–14 years requiring cardiac intervention in first year one 17 paediatric surgical centres operating during 1992–1995. A comparison group similar age sex was recruited....
<b>Objectives:</b> To assess the extent of neointimal proliferation and safety efficacy stent redilatation in patients with stents implanted for aortic coarctation or branch pulmonary artery stenosis. <b>Design:</b> Retrospective observational study. <b>Setting:</b> Tertiary referral centre. <b>Patients interventions:</b> Of 60 Palmaz stents, 12 stenosis (with 21 stented sites) underwent recatheterisation redilatation. <b>Results:</b> Neointimal thickening > 1 mm was detected six at nine...
Objectives The primary aim of this multi‐institutional study was to describe our 18‐year experience ductal stenting (DS) in infants with a duct‐dependent pulmonary circulation. secondary sought identify subgroup patients who may benefit the most using evolving technique. Background No has examined extraordinary evolution promising therapy over last two decades. Methods Between 1991 and 2009, 65 neonates (39 male, 60%) underwent cardiac catheterization for DS 3 participating centres. Patients...
Abstract Background and Aims Transcatheter pulmonary valve implantation (TPVI) is indicated to treat right-ventricular outflow tract (RVOT) dysfunction related congenital heart disease (CHD). Outcomes of TPVI with the SAPIEN 3 that are insufficiently documented were investigated in EUROPULMS3 registry 3-TPVI. Methods Patient-related, procedural, follow-up outcome data retrospectively assessed this observational cohort from 35 centres 15 countries. Results Data for 840 consecutive patients...
Staged reconstructive surgery has radically altered the prognosis of hypoplastic left heart syndrome (HLHS). Antenatal diagnosis allows for appropriate counselling, and time to consider treatment options. We report outcome from a centre where most cases are antenatally diagnosed delivered on site.Information was collated 188 consecutive HLHS between 1995 2000, including timing diagnosis, pregnancy, age at each stage surgery. At Guy's Hospital, 174 were antenatally, whom 50 underwent Fourteen...
Fifteen infants with tetralogy of Fallot, who would otherwise have required a palliative operation, underwent balloon dilatation the right ventricular outflow tract. The mean period palliation was 8.5 months (range 0-26 months). procedure performed without serious complications on 88% occasions. This preliminary study suggests that may be useful in management Fallot.
The 'hybrid procedure', consisting of surgical banding the pulmonary arteries with intraoperative stenting arterial duct, was developed as primary palliation in hypoplastic left heart syndrome (HLHS), avoiding risks cardiopulmonary bypass. In many centres, it is reserved for low birth weight, premature or unstable neonates; however, its role such high risk cases HLHS has yet to be defined.The preoperative condition all patients who underwent either hybrid Norwood procedure between 2005-2011...
