Filter by:During percutaneous cardiovascular intervention, temporary cardiac stimulation may be required. Usually this stimulation is generated via a temporary pacing catheter. In order to reduce the complexity of the procedure, a new stimulation strategy has been developed: the "Direct Wire Pacing technique".In this approach, the cardiac stimulation is provided via the guidewire connected to an external pacemaker. Previous study demonstrated the superiority of the new technique compared to the former. However this technique is likely to generate electrical pain, risk of bleeding for the patient and risk of blood exposure accident for the operators. This is why the medical device ELECTRODUCER SLEEVE has been developed. This device integrates a pacing function to the introducer and the guidewire used. The "Direct Wire Pacing technique" is simplified, secured and more reproducible.
Clinical ultrasound has become essential in emergency medicine. The guidelines are to use of echocardiography in specific contexts: dyspnea, hypotension or chest pain. The evaluation of left ventricle ejection fraction (LVEF) is one of the basic objectives of echocardiography. The reference assessment in emergency medicine is visual assessment. It suffers from poor inter-observer reproducibility. Pocket ultrasound scanners seem to meet the constraints of point-of-care ultrasound. A new tool is available on a pocket ultrasound device: the automatic evaluation of LVEF. Its interest could be to have a better inter-observer reproducibility than visual evaluation.
The aim of this study is to evaluate the rate and anatomy of the aortic wall and leaflet calcification of the FS prosthesis implanted as full root in patients younger than 60 years compared to a stented bioprostheses (Perimount Magna Ease, PM). A 3D CT scan will be used to assess the calcification score and to determine the relationship between calcification and aortic valve leaflet.
Prospective registry for multifactorial risk factor assessment, enrolling consecutive ischemic stroke/transient ischemic attack patients with structural, inflammatory, or arrhythmogenic cardiac disease, who are admitted to our University Hospital.
The objective of this study is to retrospectively gather information on patients who underwent a CIED procedure with either a CanGaroo Envelope, TYRX Envelope, or no envelope.
To assess the rates of ischemic and hemorrhagic complications of long-term antithrombotic therapy in patients with chronic coronary syndromes
This study is being conducted to provide access to and collect test data for an established nuclear medicine diagnostic imaging test called Positron Emission Tomography (PET), using a specific radioactive drug called Ammonia N-13 (Ammonia), referred to simply as an Ammonia PET scan, which is used to visualize the blood flow through the blood vessels and into the heart muscle in order to identify areas of restricted blood flow within the heart. The scanner used in this study may be a stand-alone PET scanner or a PET/CT scanner, which combines the PET scanner and a Computed Tomography (CT) scanner into a single device. Unless otherwise stated in this consent form, the term PET will be used to refer to both stand-alone PET and PET/CT scanners. While physicians have used the Ammonia PET test for many years to visualize (image) the blood flow into the heart muscle (perfusion), it is now possible to also measure the flow of blood into the heart muscle. Research studies have demonstrated clinical value in reviewing the measured blood flow values in addition to reviewing the perfusion images of blood flow into the heart muscle. Therefore, this study will establish a database of a large number of Ammonia PET measured blood flow values to serve as a future reference.
From December 6, 2019 to March 23, 2020, the research group of Qingkun Fan found a novel protein(temporarily named protein F) in heparin anticoagulant plasma of three patients with heart disease. One patient was diagnosed with multiple myeloma.However, protein F cannot be detected by serum protein electrophoresis. Preliminary studies have shown that this novel protein F have an obvious absorption peak at about 600nm. Placed at 2-8 degrees for 7 days, protein F will be isolated from heparin plasma. To the naked eye, protein F appear to be transparent jelly between the red blood cells and the plasma. The specific protein F, how it is produced, how it causes disease are still unknown. This study will explore how to detect protein F and how it is produced.
The ongoing Coronavirus (Covid-19) pandemic has recently generated the first epidemiological data on populations at risk. Currently, the risk factors, recognized for severe forms of Covid-19 infection, are elderly patients (> 70 years), obese patients, patients with chronic renal or respiratory diseases, cardiovascular history (stroke or coronary artery disease), high blood pressure, diabetes, and cancer. The population of congenital heart disease (CHD) might also be at risk, however, no data is available in this group of patients. CHD is the leading cause of birth defects, and as a result of recent medical advances, currently the number of adults with CHD exceeds the number of children, with an increasing prevalence of complex CHD. Approximately 200,000 children and 250,000 adults are living with a CHD in France today. The French Society of Cardiology, coordinator of this study, issued recommendations on March 14, 2020 for the French CHD population on the basis of expert opinions based essentially on the data published in the general population. Nevertheless, there is a need to provide scientific data on the impact of Covid-19 in the pediatric and adult CHD population. This study aims to assess the morbidity, the mortality and the risk factors associated with Covid-19 in patients with CHD in France
The intervention will involve a system that comprises a wrist-worn activity tracker and a smartphone app that acts as a medium to link to the healthcare website
