Filter by:The primary aims of this study are to 1. Develop an automated method of quantitation of RV remodeling in terms of regional RV surface curvature and area strain and assess the feasibility, repeatability and accuracy in normal subjects and patients with repaired TOF, patients with PS The secondary study aims of this study are to 1. Compare the differences of RV remodeling in repaired TOF patients, PS patients with sex and age-matched controls 2, Assess the relationship of our proposed parameters to global RV function and exercise capacity in repaired TOF patients and PS patient
A Prospective Multi-center Randomized Trial Assessing the Efficacy and Safety of Active Transfer of Plaque vs. Provisional T Stenting for the Treatment of Non-Left-Main Coronary Bifurcation Lesions.
The aims of the present project are to study possible differences in inflammatory gene expression and protein secretion in various compartments of adipose tissue being exposed during open cardiac surgery in patients with coronary heart disease undergoing coronary artery bypass surgery.
To collect information about treatment for severe aortic stenosis (AS), which affects the aortic valve in the heart. Aortic stenosis is a narrowing of the aortic valve opening, which decreases blood flow from the heart and causes symptoms such as chest pain, fainting and shortness of breath. The preferred treatment for severe aortic stenosis is aortic valve replacement surgery.
Human adipose tissue is now recognized as an acceptable, highly abundant source of adipose-derived regenerative cells (ADRCs). ADRCs are a heterogeneous or mixed population of cells found in adipose tissue including adult stem cells, leukocytes, connective tissue and vessel-associated cells. Autologous adult regenerative cells are thought to promote healing of scarred or injured tissue. While the investigators are learning more about the exact mechanisms every day, it is believed that this heterogeneous population of cells influences the local environment via cell-to-cell signaling, immune modulation, and differentiation into other cell types. The use of ADRCs in the treatment of many different medical conditions (including cardiovascular disease, soft tissue defects, wound healing, and many more) is being evaluated in numerous clinical and preclinical studies around the world. While there is a considerable amount of information regarding the cellular composition of ADRCs isolated from healthy donors, basically there is no much data regarding the ADRC composition from cardiac patients. In this study, adipose tissue or cells from chronic heart ischemia patients, that would otherwise be thrown away in waste, will be provided to researchers who will study these cells with the objective to characterize ADRCs derived from patients with a heart disease and to compare if a heart disease state does impact ADRC cell composition.
The aims of the present study are to measure dynamic changes over time in the plasma level of SDF-1α in patients with confirmed diagnoses of AMI, AF and CHF and in so doing: 1. Monitor the plasma level of SDF-1α at the diagnosis, during and after the long term treatment of AMI, AF and CHF. The SDF-1α level of patients is expected to decrease during treatment of the aforementioned conditions. 2. Correlate the plasma level of SDF-1α in relation to clinical, biochemical characteristics of Acute Myocardial Infarction(AMI), Atrial Fibrillation(AF) and Congestive Heart Failure (CHF). In so doing, the investigators expect that SDF-1α will correlate with the severity of heart disease. 3. Study the dynamic of SDF-1α pertaining to its property as prognostic indicator for the long term follow up risk of readmission and mortality of patients diagnosed with AMI, AF or CHF.
The study is a prospective, non-randomised, open label clinical study to assess the safety of the Bioabsorbable Pulmonary Valved (PV) conduit (PV-001) in subjects > 2 years and < 22 years of age, undergoing Right Ventricular Outflow Tract (RVOT) reconstruction. It is a first in man feasibility study which will include 10-12 patients in up to 6 sites in Europe. The primary objective of the study is to assess the survival rate of subjects at 6 months following implantation of the Bioabsorbable Pulmonary Valved Conduit (PV-001). Secondary objectives: 1. The survival rate of subjects at 12 months following implantation of the Bioabsorbable Pulmonary Valved Conduit (PV-001) 2. The percentage of conduit failure at 6 months and 12 months, where conduit failure includes the need for reintervention or reoperation. 3. The pressure gradient across the pulmonary valve will have an acceptable level at 12 months follow up. 4. The pulmonary regurgitation measured will not exceed a moderate grading at 12 months follow up. 5. To evaluate the usability of the Bioabsorbable Pulmonary Valved Conduit (PV-001) during the surgical procedure, using exploratory parameters Long term safety will be assessed up to 60 months post implantation.
The aim of the Danish Organization for Randomized Trials with Clinical Outcome (SORT OUT) is to compare the safety and efficacy of the polymer-free Biolimus-eluting BIOFREEDOM stent with a biodegradable-polymer Sirolimus-eluting ORSIRO stent in a population-based setting, using registry detection of clinically driven events
This study was designed to evaluate the correlation between pre-operative FFR and the functionality of arterial bypass grafts six months after coronary artery bypass grafting. Patients with multi-vessel coronary artery disease will undergo both a coronary angiogram and FFR during their diagnostic workup. All patients will be referred for surgical revascularization (CABG) with planned use of arterial grafts. Six months after surgery, patients will undergo an angiogram to assess the functionality of the bypass graft and anastomosis.
The overall goal of this project is to determine the role of anesthetic management in children undergoing cardiac surgery utilizing CPB in the setting of fast tracking and early extubation. An ideal anesthetic technique would ensure abolishing or diminishing stress response as would be evident by the stress markers levels and the level of two cerebral injury biomarkers (S 100 B and NSE). This should translate to better immediate postoperative outcome and hopefully improve both the short and the long term neurodevelopmental outcome in these children. The project is prospective, randomized and blinded study. The first and second aim of the study should be conducted over 2 year period. Our long term aim will be concluded when these children reach the school age.
