Filter by:Heart murmurs are commonly discovered in young children during clinical encounters in general practice. Heart murmurs might signal a structural cardiac disease that need to be treated, such as atrial septal defect. Thus, children with heart murmurs are routinely referred to comprehensive cardiac examination at a paediatric hospital department featuring echocardiography ('gold standard'). However, the great majority of such murmurs are innocent or physiological; ie., they do not represent a cardiac disorder. The prevalence of such innocent murmurs during routine random auscultation is estimated at 30 %. It would be advantageous if patients with a heart disease to a greater extent could be identified at the general practitioners' office: - Healthy children would not be exposed to comprehensive cardiac examination - The burden on the family would subside. - Scarce medical resources in highly specialized departments would be better allocated, to the benefit of patients with real heart disease. The primary aim of this study is to establish the predictive value of cardiac markers in children with heart murmurs. Secondary aims are a) To do a pilot study of pediatric cardiac ultrasound examination in general practice; b) To establish age-adjusted reference range for cardiac markers in children, and c) To explore aspects of cardiovascular physiology in children. The investigators will include a total of 500 children aged 4 weeks to 10 years who is consecutively referred to the Dept. of Paediatrics, Akershus University Hospital, for assessment of heart murmurs. All participants will be subjected to clinical examination, symptom assessment, pulse oximetry, blood sampling (for troponin T, proBNP and other biomarkers), ECG recording, and echocardiography. A randomized subgroup of children will also undergo echocardiography performed by a general practitioner who has not received formal training in pediatric cardiology. The value of possible predictors will be assessed through the construction of Receiver Operating Characteristics (ROC) curves, and calculation of negative predictive value.
This study will demonstrate the safety and effectiveness of the Edwards Lifesciences SAPIEN 3/SAPIEN 3 Ultra RESILIA Transcatheter Heart Valve (THV) Systems in subjects with a dysfunctional right ventricular outflow tract (RVOT) conduit or previously implanted valve in the pulmonic position with a clinical indication for intervention.
The study is a nested case-control study and the purpose is to describe the status of key nutrients(eg.folic acid and vitamins) supplementation among pregnant women in Shanghai, to find out the association between the level of serum key nutrients during peri-conceptional period and the incidence of congenital heart defects (CHD) in newborn, and to provide better preconception care.
This study will evaluate the use of x-ray fused with MR images as an imaging tool to help guide catheter tools during diagnostic and therapeutic cardiac catheterization procedures.
Pulse oximetry screening of newborn infants increases early detection of critical congenital heart disease and minimises the risk of circulatory collapse before surgery. This study provides an update on the implementation of pulse oximetry screening in Turkey
A study about accuracy of pulse oximeter with hypoxemic measurements (Blue sensor, Masimo, Irvine, CA, USA) in children with cyanotic congenital heart disease
Osteopathic care impact on postoperative pain assessed by osteopathic session, evaluated by EVENDOL scale surgery on children with congenital heart disease
The purpose of this study is to retrospectively review our preliminary experience during a surgical trip to Tuxtla, Mexico, using suggamadex to reverse neuromuscular blockade following CPB and cardiac surgery for repair of CHD in infants and children.
To answer the research question: "Would image-based modelling result in different clinical decisions as compared to clinical practice guidelines?", we will conduct a randomized controlled experiment in which we will compare the hypothetical decisions made by interventional cardiologists who are presented with imaging parameters currently recommended by clinical practice guidelines vs. hypothetical decisions made by interventional cardiologists receiving an expanded list of parameters, including simulation modelling.
Patients with hypoplastic left heart syndrome and other single right ventricle lesions who have undergone the Fontan procedure have a high risk of neurodevelopmental disorders that affect quality of life and adulthood employment. This study will leverage the ongoing National Heart, Lung, and Blood Institute (NHLBI)-funded Single Ventricle Reconstruction Study by using innovative graph measures of brain connectivity to elucidate how alterations of the "connectome" in children with critical congenital heart disease are associated with developmental disabilities and their associated clinical risk factors. Improved understanding of these interrelationships may facilitate development of targeted interventions to improve outcome in the soaring population of adult Fontan survivors.
