Prolonged periods of cardiopulmonary bypass (CPB) cause high levels of plasma free haemoglobin(Hb) and are associated with increased morbidity. We hypothesized that repletion of nitric oxide (NO) during and after the surgical procedure on CPB may protect against endothelium dysfunction and organ failure caused by plasma-Hb induced NO scavenging.
Our main hypothesis on the present study is that new parameters such as risk-taking behavior, patients motivation, health related quality of life, new biomarkers and more precise echocardiography measures in addition to traditional parameters will improve pre-operative risk assessment in patients with AS and better guide patients and doctors in decision whether to operate or not.
To monitor the long-term performance of the CE Marked NeoChord Artificial Chordae Delivery System
The primary objective of this study is to evaluate sternal bone healing following a full median sternotomy versus standard of care for sternal closure with wire cerclage. Additional outcomes on post-operative pain and analgesic usage, patient function and quality of life, and complications will also be collected. A health economics study will also be conducted, in which cost and billing data will be collected from sites participating in this clinical study.
The study aim is: 1. To examine aortic tissue by light microscopy 2. To examine aortic tissue by electron microscopy 3. To study changes in the epigenome and transcriptome of the X chromosome specific to aortic tissue. 4. To examine aortic tissue using biochemistry including proteomics. 5. To establish the karyotype of fibroblasts with standard chromosome examination on 10 meta-phases as well as by fluorescent in situ hybridization (FISH) with probes covering the X and Y chromosome. Using the latter 200 meta-phases will be examined. 30 controls who did not die from aortic dissection or dilation will be recruited from The Department of Forensic Medicine at Aarhus University Hospital. The investigators will subject samples of aortic tissue from women undergoing prophylactic aortic surgery due to either Marfan syndrome or bicuspid aortic valve to the same panel of examinations (except karyotyping). Lastly the investigators will compare the results from the three groups (Turner syndrome, Marfan syndrome and Bicuspid aortic valve).
The purpose of this registry is to gather information on patients with bicuspid aortic valve disease.
The recent developments of research on iPS (induced pluripotent stem) cells lead to the establishment of mature cell lines such as cardiomyocytes or valvular interstitial cells with genetic and cellular characteristics of the donors. These cells represent a biological material more readily available to identify the pathophysiological mechanisms involved in the diseases of BrS or ERS patients, which will lead to the identification of genetic markers.
The purpose of this study is to compare early mitral valve repair versus a watchful waiting strategy in asymptomatic patients with severe organic mitral valve regurgitation and preserved left ventricular function.
We aim to investigate the efficacy of N-acetylcysteine (NAC) to attenuate acute renal dysfunction in patients with rheumatic valvular heart disease undergoing single valve replacement.
