Filter by:With this project the investigators aim to investigate whether premature ventricular complexes (PVC) have a prognostic significance in persons without structural heart disease. Further the investigators look at the possible connection between PVC-morphology and clinical outcome and investigate whether advanced cardiac imaging-methods may identify subtle signs of heart disease in PVC-patients with normal findings at echocardiography.
Acute normovolemic hemodilution (ANH) has long been employed for reducing allogenic blood transfusion for cardiac surgery, and hydroxyethyl starch has been used as an intravenous replacement fluid during ANH procedure. However, possible impact of ANH employing HES on blood viscosity and oxygen delivery have not been well investigated in patients undergoing off-pump coronary artery bypass (OPCAB) surgery . Anesthesia is induced and maintained by using propofol-remifentanil-rocuronium in OPCAB surgery (n=21). ANH is performed by using 5 ml/kg of blood salvage and administering 5 ml/kg of balanced HES 130/0.42 (Tetraspan™) for 15 min during vascular graft harvesting. For the present study, three arterial blood samples (3 ml each) are taken before (Sample 1) and after ANH (sample 2 and 3) and they are stored in 3 tubes. Sample 3 (in tube) undergoes further 30% in-vitro dilution by adding 1-1.5 ml HES. By using a scanning capillary tube viscometer (Hemovister™), Blood viscosity at low shear rate (5/sec) of the three samples are determined. By using a formula with blood viscosity and hematocrit, tissue O2 delivery index (TODI, = hematocrit/viscosity at 5/sec) is calculated.
The investigators are interested in determining the best surgical technique to correct functional mitral regurgitation, as there is currently not one technique that is established to work better than the other. The technique used in current clinical practice is undersizing mitral annuloplasty (UMA), in which a prosthetic ring is implanted onto the mitral valve to correct the leakage. Though widely adopted, durability of the repair is less, as 58% of the patients present with recurrent FMR within 2 years. There are no specific algorithms to predict who might have UMA failure, but research indicates that some geometric indices might be strong predictors. The investigators are interested in testing the hypothesis that, elevated lateral inter-papillary muscle separation (IPMS) is a predictor of post-UMA recurrence of FMR at 12 months. In the first part of this study, the study team will measure lateral IPMS before surgery, and relate to post-surgery FMR severity at discharge/30 days, 6 months and 12 months. A relatively newer technique is papillary muscle approximation (PMA), in which a suture draws together the two muscles that connect the mitral valve to the heart muscle prior to performing UMA. This reduces the lateral inter-papillary muscle separation (IPMS) and is expected to improve the durability of UMA. In the second part of this study, the investigators will perform PMA and UMA together and determine if FMR severity is reduced at discharge/30 days, 6 months and 12 months.
To observe the effect of sevoflurane on the concentration of S100β and regional cerebral oxygen saturation in infants with congenital heart disease undergoing cardiac surgery.
Ventricular septal defects (VSD) are the most common cardiac congenital heart defect (about 1/3 of patients with congenital heart disease). VSD management is related to hemodynamics and anatomical localization and the occurrence of complications. Small perimembranous VSD without pulmonary hypertension and without significant left to right shunting are tolerated, whereas large VSD with pulmonary hypertension require early surgical management in the first months of life. The management uncertainties concern the medium-sized perimembranous VSD causing a significant left-right shunt but without pulmonary hypertension, which are of variable treatment (surgical correction, percutaneous treatment, medical or abstention). There are no recommendations or consensus on the preferred indication of a therapeutic attitude. The Pediatric and Congenital Cardiology Subsidiary, within the French Society of Cardiology, set up an observatory of perimembranous VSD with significant shunting, without pulmonary hypertension the objectives of this study are: - To study the incidence of cardiovascular events in perimembranous VSD and search for predictive anatomical markers of events. - To study the evolution of echocardiographic and functional data of patients having percutaneous or surgical closure compared to patient managed medically. This observatory will provide a better understanding of the therapeutic algorithm in the management of VSD with pulmonary overload without pulmonary hypertension.
The closed-loop stimulation (CLS) algorithm is a novel sensor-based technology that relies on the change in myocardial systolic impedance for modulation of the heart rate during physical and emotional stress.3 The pacing algorithm has been shown to be highly effective for a wide range of clinical scenarios. Despite the fact that congenital heart disease (CHD) patients are likely to derive significant benefit in terms of functional ability and aerobic capacity using this novel technology, the CLS system has not been adequately studied in this population. As many CHD patients also undergo epicardial placement of pacing systems at the time of concomitant cardiac surgery, CLS has been less often utilized in this population given almost no data in the setting of surgical electrode placement. The present study intends to examine the benefits of the CLS algorithm in the CHD population, employing the use of epicardial pacemaker systems in the study protocol.
Children with congenital heart disease are at risk for neurodevelopmental disorders, these disorders impacting their quality of life and their integration into society. The aim of this study is to detect neurodevelopmental disorders in children (aged from 6 to 66 months) with congenital heart disease in Nord-Pas-De-Calais (France) and to evaluate the frequency and risk factors of these neurodevelopmental disorders for a better follow-up. This study will help implementing a specific program for the evaluation and management of neurodevelopmental disorders in children suffering from congenital heart disease in Nord-Pas-De-Calais and more globally, in the region Hauts-De-France.
Mood disorders, anxiety disorders, and trauma-related stress (MD\AD\TRS) are common among men, particularly those suffering from heart disease (HD). MD\AD\TRS are significantly related to exacerbation of HD symptoms that often lead to death. Unfortunately, men are significantly less likely than women to seek and receive appropriate treatment for their mental health issues including MD\AD\TRS. Furthermore, there is little literature about the use of the stepped care model in the Canadian setting. The overarching goal of this interventional program is therefore to prevent, early detect and treat MD\AD\TRS in men living with HD. This Participatory Action Research aims to implement a stepped-care model for MD\AD\TRS in men in New Brunswick, Ontario, and quebec. The second phase of the project proposes a quantitative study that will consist of testing the effectiveness and acceptability (by the men and the involved health professionals) of the stepped-care model. It will offer to post ACS-males a mental health related component presently not available in the typical services of the NB health system. Data will be collected at baseline (0 month) and at four follow-up (each 3-months) sessions to manage the progress of each participant throughout their 12-month journey in the study. Typical sociodemographic data will be collected, along with a questionnaire on Masculinity Norms, Couples Satisfaction (when applicable), and four mental health assessment tools.
Sexual health is an important marker of individual quality of life and well-being of patients. Sexual dysfunction (SD) is common in patients with heart disease. Screening and management are recommended. Cardiac rehabilitation (CR) seems to be a privileged moment to address this problem, but the management is often insufficient. The main objective of the study was to evaluate the prevalence of SD in patients in CR in the Champagne-Ardenne region. Secondary objectives were to describe SD most frequently encountered, to identify risk factors of SD, to compare the feelings of patients about their sex life, before and after an acute cardiac event and to collect an estimate of the need for care by a dedicated sexology workshop. The investigators conducted an observational multicenter prospective study for descriptive and analytical purposes after approval by the Institutional review board. An anonymous questionnaire was distributed from June 1 to September 1, 2017 in patients participating in a cardiac rehabilitation program in the various centers in the region.
