Filter by:Heart disease symptoms are a frequent reason of consultation in general medical practice. Only a few general practitioners are equipped with a 12 lead Electrocardiography (ECG) whereas this test is extremely useful for diagnosis orientation in cases of cardiac diseases.Cardiosecur allows the realization of a 15 or 22 leads ECG with only 4 electrodes connected to a smartphone or a tablet with an automatic interpretation function. The goal of the study is to evaluate the diagnostic value of Cardiosecur device regarding cardiac symptoms in family practice.
Transesophageal echocardiography (TEE) has become a standard monitoring tool during cardiac surgery. It allows continuous accurate assessment of heart structures and function without interfering with the surgery and the anesthetics. The imaging of cardiac structures is used to direct optimal surgical intervention and assess surgical results. Cardiac output (CO) is the result of stroke volume (SV) multiplied by the heart rate. Measurement of cardiac output (CO) is used to quantify the performance of the left ventricle. It is commonly achieved using a pulmonary artery catheter (PAC) (also known ad Swann-Ganz catheter). A known amount of saline solution is injected in the proximal part of the catheter and the variation of blood temperature detected at the tip. Cardiac output is measured based on the duration and degree of temperature change. This method remains an accepted gold standard. TEE allows measurement of cardiac output using a number of different 2D and 3D imaging modalities. Although current guidelines identify the Method of the Disks(MOD) as the gold standard other technique could potentially be more precise. In this study, the investigators want to assess the accuracy of four different TEE methods to measure cardiac output compared with Thermodilution as a standard of care.
The purpose of this pilot study is to obtain both near valve and downstream flow characteristics, using 3D transthoracic echocardiography and 4D flow MRI respectively, in an existing patient population at Northwestern Memorial Hospital, to determine the hinge washout characteristics and downstream flow patterns of the On-X valve and compared to competing designs.
Background: Researchers do not know much about the causes of congenital heart disease (CHD). They do know that many factors play a role. Some factors are environmental. Some are genetic. But few specific factors have been identified. And researchers do not know how many involve genes. They want to study data that has already been collected from people with CHD and their families. Objectives: To identify genetic variations related to CHD. To study molecules related to vascular disease in order to learn new ways to treat it. Eligibility: People who already participated in the Pediatric Cardiac Genomics Consortium (PCGC) study Design: Researchers will study data that was already collected in the PCGC. There will be no active participants. Researchers will get access to the data through the coordinating center. They will not download data to local storage devices. The data will have no personally identifying information....
Rheumatic heart disease (RHD) affects at least 32.9 million people, mostly children living in low-resource settings. Long-term intramuscular benzathine penicillin G (BPG) prophylaxis is proven to prevent progression of chronic valve changes in patients with established rheumatic heart disease (RHD) and to allow regression of valve changes in patients with a history of acute rheumatic fever (ARF) with mild RHD. However, in low-resource settings ARF is an elusive diagnosis, and most patients (85%) are diagnosed only when RHD is severe and irreversible, medications ineffective, and surgical intervention is expensive and/or unavailable. Identification of latent RHD might be an opportunity to substantially reduce RHD morbidity and mortality. However, detection of latent RHD is only important if outcomes are improved. The appropriate management of children with latent RHD is unknown and no formal recommendations exist. While some clinicians prescribe penicillin prophylaxis for children with latent RHD, clinical equipoise exists regarding the best practice. To fill this gap, the investigators propose a randomized controlled trial in children with latent RHD to evaluate the efficacy of BPG prophylaxis compared to no prophylaxis. Our primary outcome measure is progression of valvular changes on echocardiogram at 2 years. A sample size of 916 children is needed to detect a 50% reduction of progression (expected range 7.5-12.5% progression in BPG-arm vs. 15%-25% progression in control-arm) with 90% power. AIM 1: To compare the proportion of children (aged 5-17 years) with latent RHD receiving BPG prophylaxis who progress to worse valvular disease at 2-years compared to children not receiving BPG prophylaxis. Hypothesis 1: Prophylaxis with BPG will result in fewer children with latent RHD showing progression of echocardiographic valve changes at 2 years compared to children with latent RHD not receiving BPG prophylaxis. (The investigators expect at least a 50% relative reduction in progression in the BPG arm: range 15%-25% control arm vs. 7.5-12.5% BPG-arm.) AIM 2: To compare the proportion of children (aged 5-17 years) with latent RHD receiving BPG prophylaxis who regress to improved valvular disease at 2-years compared to children not receiving BPG prophylaxis. Hypothesis 2: Prophylaxis with BPG will result in more children with latent RHD showing regression of echocardiographic valve changes by 2 years compared to children with latent RHD not receiving BPG prophylaxis. (The investigators expect at least a 50% relative increase in regression in the BPG arm: range 10-20% control arm vs. 20-40% BPG arm.) This study is highly significant because it will establish if BPG prophylaxis improves outcomes for children with latent RHD. Feasibility will be ensured through the experience, resources, community support, and accessible patient population of our investigational team. The results of our study will have high impact, immediately informing international policy on the standard of care for children diagnosed with latent RHD and shaping, over 2-3 years, practical and scalable programs that could substantially decrease the global burden of RHD.
The objective of this study is to compare the relative capability of Stethee® (new wireless digital stethoscope) and 3M™ Littmann® Classic III™ (conventional stethoscope) in the identification of manikin-simulated heart sounds by medical doctors. A randomised, non-blinded, two-period crossover, non-inferiority design will be used to compare the acoustic performance of the two stethoscopes. We aim to determine if Stethee® is as effective as 3M™ Littmann® Classic III™ for auscultation of simulated heart sounds, and whether Stethee® could be recommended for use in clinical practice based on a non-inferior comparison with 3M™ Littmann® Classic III™.
Researchers will compare the effects of lidocaine versus air, as a way to fill the breathing tube cuff which is gently inflated to hold in place the trachea (airway) during surgery. Air is the traditional method used to inflate the breathing tube cuff. Researchers wish to find if lidocaine works better than air to facilitate tolerance to the breathing tube (decreased coughing, sore throat, hoarseness). They also want to learn more about its effectiveness for this particular surgical intervention.
The Transition Navigator Trial (TNT) is a pragmatic randomized controlled trial evaluating the effectiveness of usual care plus a patient navigator service versus usual care plus newsletters and other educational materials, to improve transition outcomes among adolescents aged 16-21 who have chronic health conditions requiring transfer to adult specialty care. The study will provide urgently needed data to guide health care providers and policy makers regarding the provision of coordinated transition care. These results have the potential to: 1. Change care delivery 2. Improve health outcomes 3. Improve the experiences of young adult transition to adult care
This study is comparing the use of Kcentra vs. standard transfusion in patients undergoing heart transplantation surgery. Half of the patients will receive Kcentra, while the other half will receive fresh frozen plasma.
The study aim is to assess polyethylene glycol (PEG) coated collagen patch (Hemopatch) on the quality of drainage after surgery, the length of hospital stay, the number of reoperations due to haemorrhage and treatment cost. The study will be conducted in 200 patients undergoing Coronary Artery Bypass Grafting (CABG) with the use of extracorporeal circulation and Internal mammary Artery (IMA) harvesting. Traditional method of haemostasis will be applied in 100 patients and Hemopatch will be additionally used in 100 subjects to prevent haemorrhage after IMA harvesting and sternum closure.
