Filter by:In this pilot study investigators propose to explore the effects of a locally delivered inhaled pulmonary vasodilator (inhaled treprostinil) on exercise performance, pulmonary blood flow, venous pressure response and vascular function in stable Fontan patients. Investigators will also assess the effects of resting and acute rises in exercise induced systemic venous pressure on liver stiffness and will also assess whether treprostinil will attenuate the acute stiffness increase that investigators expect to see. This will be a prospective, randomized, double-blinded placebo controlled, crossover trial. Following recruitment and informed consent, each participant will undergo three study visits, including baseline testing (visit 1), followed by two sets of exercise and vascular function tests (visit 2 and visit 3) at CCHMC. Twenty-six patients will be enrolled in this study.
The investigators objective is to assess the effectiveness of an opioid sparing multimodal approach for enhancing the recovery in Cardiac Surgical patients. This model would use a combination of intravenous (Dexmedetomidine, Ketamine, Lidocaine) and Spinal (Morphine) drugs.
Cardiogoniometry is a technique to process and evaluate vectorcardiography from regular ECG acquisitions. Vectorcardiography has a long tradition in cardiology for providing comprehensive information on myocardial function and integrity. In recent years, computer assisted analysis has allowed automated interpretation of vectorcardiography with promising results in comparison to standard ECG for identifying patients with coronary heart disease. This study aims to investigate the utility of cardiogoniometry for noninvasively identifying patients who are at risk from coronary heart disease.
The Cardioband Transcatheter System (Cardioband) is indicated for the treatment of secondary (functional) mitral regurgitation (FMR). The Cardioband is a transcatheter system, deployed on the beating heart through a transseptal approach. The Cardioband is deployed along the posterior annulus of the mitral valve (MV) and is adjusted under trans-esophageal guidance on the beating heart. A CE mark study with 30 subjects has been completed and documented reduction of severity of mitral regurgitation (MR) and improvement in 6- minute walk test in subjects with moderate to severe MR. Study objectives are to test the efficacy of the Cardioband in improving MR and heart failure symptoms in patients with symptomatic (New York Heart Association (NYHA) Class III-IVa), severe MR in the post-marketing setting, And to evaluate the safety of the Cardioband system in the post-marketing setting.
The purpose of this study is to to examine the effects of atorvastatin, a type of statin, on changes to the heart among women undergoing breast cancer treatment. Atorvastatin may reduce or eliminate the harmful effects of chemotherapy treatment to the heart tissue of breast cancer patients.
The purpose of this study is to compare different combinations of anesthetic drugs (cause loss of sensation) in terms of effectiveness, adverse effects, pain relief, and patient comfort for cardiac electrophysiology procedures. In addition, the investigators are studying the different anesthetic combinations to determine the best approach in terms of identification and treatment of arrhythmias.
Patients with congenital heart disease have long been discouraged from participating in physical exercise which has led to impaired exercise capacity in this population. Since low physical and cardiorespiratory fitness has been shown to be a predictor for hospitalization and mortality in grown-up patients with congenital heart disease (GUCH), aerobic endurance training has been recommended recently to improve exercise capacity. The aim of this study is to compare two types of training, namely high-intensity interval training (HIIT) and moderate-intensity continuous exercise (MICE), with regard to improving exercise capacity without adverse effects on heart structure, function and rhythm in the setting of a 12-week outpatient cardiac rehabilitation (CR) program in GUCH with a remaining pathology involving the right and/or left ventricles. Primary endpoint will be change in exercise capacity (maximal oxygen consumption) over the 12-week CR. Secondary endpoints will be changes of the right or left ventricles as well as vascular function. Patients with GUCH and reduced function of the right ventricle will be recruited and informed about the study within the first two weeks of CR. At the end of week 3 of the CR with supervised MICE, randomization to 9 weeks of twice weekly either HIIT or MICE takes place. MICE training is performed at an intensity of 70-85% of maximum heart rate (HRmax) for 38 min. HIIT consists of four 4 min bouts of high-intensity exercise (90-95% of HRmax), interspersed by 3 min low-intensity intervals (50-60% of HRmax). All patients complete one additional endurance activity per week in their own time with a duration of 30-60 min at moderate intensity monitored by their smart phone. Change in peak oxygen uptake as well as maximal exercise capacity at the end of an incremental cardiopulmonary exercise test will be assessed between week 3 and 12. Vascular function will be assessed at the same time. Volumes and function of the right and left ventricles will be measured by cardiac magnetic resonance imaging (CMR) upon inclusion into the study and at completion of the intervention. Furthermore, laboratory markers for heart failure as well as occurrence of irregular fast heart beats will be assessed.
Medical progress and modification of lifestyles have prolonged life expectancy, despite the development of chronic diseases. The support and care are often provided by a network of informal caregivers composed of family, friends, and neighbors. They became essential to help maintening the elderly persons to live at home. It has been demonstrated that the importance and the diversity of informal tasks may jeopardize their own physical, mental and social well-being. The aim of the Informal Carers of Elderly Cohort is to define, through a longitudinal study of their life course, the profiles of caregivers of patients with a diagnosis of one of the following diseases: cancer (breast, prostate, colon-rectum), neuro-degenerative diseases (Parkinson's disease, Alzheimer's and similar diseases), neuro-vascular diseases (Cerebrovascular Accident (CVA)), Age-related Macular Degeneration(AMD) and heart disease (heart failure), aged ≥ 60 years old and living in Burgundy or Franche-Comte. By following the different phases of the caregiving relationship from the announcement of the diagnosis, it will be possible to assess the quality of life of caregivers and evaluate the implementation of a pragmatic social action to help informal caregivers through a randomized intervention trial nested in the cohort. Thanks to an analytical and longitudinal definition of the profiles of informal caregivers, this study could gather precise information on their life courses and their health trajectory by identifying the consequences associated with the concept of their role of aid in care. In addition, the randomized intervention trial will explore the efficacy, in terms of quality of life, and efficiency of a social action to support the caregivers. These data will allow to identify strategies that could be used to improve the existing sources of aid and to propose new approaches to help caregivers. This study will provide the opportunity to identify the most relevant means of support and to give an impulse for new healthcare policies.
Cyanotic congenital cardiac patients require higher hemoglobin concentrations (red blood cell levels) for optimal oxygen delivery to the body. Prophylactic erythropoietin (EPO) and iron can prevent and/or decrease the amount of blood transfusions needed in this population. We seek to investigate if EPO and iron make a clinically significant difference in the number of transfusions given to these patients and the morbidity associated with it.
The aim is to create a database including recordings of ECG data recorded in an MRI acquisition
