Filter by:PURPOSE: The aim of this study is to investigate the effect of trunk stabilizing exercises on sternal instability in patients with median sternotomy after heart valve surgery
The PROTEMBO C Trial is an international, multi-center, single arm, non-inferiority study of the safety and performance of using the ProtEmbo System for cerebral embolic protection in subjects with severe native aortic valve stenosis indicated for TAVR.
Hypotension with potentially serious consequences for organ perfusion is a common complication in extracorporeal procedures such as heart-lung-machine. The exact reasons for this are still insufficiently clarified. Probably periinterventional vasorelaxant released substances play a crucial role in these procedures. These substances could be due to contact of blood cells with the Membrane in the HLM arise. In this project the hypothesis will be checked, if EETs / DHETs are released by Erythrocytes during this extracorporeal procedure and thus act as potential candidate products for the result of hypotonic phases during usage of heart-lung-machine. We will determine differences in RBC fatty acids profiling in patients before and after heart-lung-machine intervention. RBC fatty acids profiling will be achieved by using targeted HPLC-MS mass spectrometry. It is believed that during HLM there is an increase in EETs / DHETs in the serum and in the erythrocytes. It is believed that shear forces play an important role in the release of erythrocyte EETs / DHETs.
This study investigates the association between level of suPAR and valvular heart disease in patients who have severe aortic stenosis or severe aortic regurgitation using commercially available suPARnostic standard enzyme-linked immunosorbent assay (ViroGates, Denmark)
Valvular heart diseases are significant problem in Polish population. Coexistence of coronary artery disease in patients with VHD increases the risk of death and affects further therapeutic strategy. The aim of the study is analysis the epidemiology and the long-term prognosis among patients with VHD.
The National Tunisian Registry of Valvulopathies is an observational, prospective and multicenter study aiming to assess the epidemiological, clinical and therapeutic profile of valve disease in tunisian departments of cardiology. Cardiologists from both sectors (public and private) are participating in the study, with 37 investigational centers. Data will be captured electronically by DACIMA Clinical Suite, according to FDA 21 CFR part 11 (Food and Drug Administration 21 Code of Federal Regulations part 11), HIPAA (Health Insurance Portability and Accountability Act) & ICH (International Conference on Harmonisation) requirements.
Recovery after surgery depends on psychological factors such as preoperative information, expectations and surgery-associated anxiety. Prior studies have shown that even short preoperative psychological interventions can improve postoperative outcomes in heart surgery patients. However, what content works best for which patient group and how long an intervention has to be is still largely unknown. The aims of this study are thus to examine if the developed preoperative psychological intervention (i) reduces preoperative anxiety, (ii) increases positive expectations, and (iii) improves the long-term outcome postoperative recovery. Therefore, a brief intervention has been developed. Heart valve patients who undergo a heart surgery will be randomized into two groups (Control vs. intervention group) after baseline assessment. Following this the intervention group will participate in the psychological intervention (30-40 minutes). To increase patients' positive expectations the intervention will focus on treatment outcome expectations and personal control expectations. Furthermore, patients in the intervention group will have two booster-telephone calls (four and eight weeks after the surgery) to check if their developed plans work out. The control group will receive the standard medical procedure. Both groups will fill out questionnaires again at the evening before the surgery, around one week after the surgery and three months after surgery.
Being easy, bedside, non-expensive, noninvasive and radiation free, there has been a growing interest in the implementation of lung ultrasound in critical care management in the last decade, cardiac surgery was not an exception in both adult and pediatric surgeries Many predictors for open heart surgery outcomes have been studied in past years including The Society of Thoracic Surgeons (STS) risk score and the EuroSCORE (ES), preoperative clinical condition, associated chronic diseases, type of surgery, age, duration of cardiopulmonary bypass and brain natriuretic peptide (BNP), cystatin-C A recent study described the use of a novel postoperative lung ultrasound score scanning for B lines which denote subpleural interstitial edema in various lung regions for predicting critical care length of stay in pediatric cardiac surgeries. The objective of the current study is to evaluate the role of the new lung ultrasound score in predicting the length of postoperative intensive care stay after adult open heart surgeries.
Pivotal trial to evaluate the safety and effectiveness of the Edwards EVOQUE tricuspid valve replacement system
The purpose of this study is to assess exercise patterns during home-based or center-based cardiac rehabilitation participation.
