Filter by:The main purpose of this study is to define the complex genetic and pathogenic basis of thoracic aortic aneurysm (TAA) and other forms of aortopathy and/or aortic valve disease by identifying novel disease-causing genes and by identifying important genetic modifiers for aortic and aortic valve disease severity.
Prospective, controlled, multicenter clinical investigation with four trial cohorts: Randomized, Non-repairable, Severe Mitral Annular Calcification (MAC) and Severe Mitral Annular Calcification Continued Access Protocol (MAC CAP). Subjects in the Randomized cohort will be randomized in a 1:1 ratio to the trial device or to the MitraClip system. Subjects in the Non-repairable, Severe MAC, and Severe MAC CAP cohorts will receive the trial device. The objective of the Clinical Trial to Evaluate the Safety and Effectiveness of Using the Tendyne Transcatheter Mitral Valve System for the Treatment of Symptomatic Mitral Regurgitation (SUMMIT) is to evaluate the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System for the treatment of patients with symptomatic, moderate-to-severe or severe mitral regurgitation or for patients with symptomatic mitral valve disease due to severe mitral annular calcification. This randomized controlled trial will provide the opportunity to evaluate the safety and clinical benefits of the Tendyne Transcatheter Mitral Valve System compared to the MitraClip System in patients with symptomatic, moderate-to-severe or severe mitral regurgitation, within approved MitraClip indications. In addition, the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System will be evaluated in patients with severe mitral annular calcification who are at prohibitive risk for mitral valve surgery. Patients who are not suitable for mitral valve surgery for reasons other than severe mitral annular calcification and are also not suitable for transcatheter repair with MitraClip, will be enrolled in the Non-repairable cohort. Subjects will be seen at screening, pre- and post-procedure, discharge, 30 days, 3 months, 6 months, and annually through 5 years.
To explore predictors of major cardio-vascular events after cardiac surgery and trans-catheter valve implantation with a specific interest in studying mechanisms linking pre-operative leukocyte, fat and myocardial phenotypes with post-intervention outcomes.
It is unclear to what extent systemic fluid overload has an impact on T1-mapping results by cardiovascular mangetic resonance imaging. In this study, patients will undergo body composition monitoring assessing systemic fluid overload and T1-mapping using MOLLI by cardiovacular magnetic resonance imaging in order to investigate a possible association with each other.
By bioelectrical impedance spectroscopy (BIS) association of fluid status in patients with valvular heart disease and cardiovascular outcome will be assessed.
The purpose of this study is to assess the safety and performance of the Trialign System for the treatment of symptomatic chronic functional tricuspid regurgitation (FTR) in patients with a minimum of moderate tricuspid regurgitation. The procedure will be performed with the PTVAS device using a non-surgical percutaneous approach to tricuspid valve repair in patients who have FTR with a minimum of moderate tricuspid regurgitation.
To explore the effect of intraoperative sodium creatine phosphate on myocardial protection in patients undergoing valve surgery
Current European Society of Cardiology Guidelines recommend concomitant atrial fibrillation (AF) ablation for all symptomatic patients undergoing other cardiac surgeries, but the safety and potential benefits of concomitant atrial fibrillation (AF) ablation at the time of double valve replacement remains unexamined. A retrospective review of patients with AF who underwent double valve replacement with or without concomitant surgical ablation in our institute starting from April 2006.
The objective of this prospective, randomized, blinded clinical trial is to assess the safety and efficacy of the Carillon Mitral Contour System in treating heart failure with functional regurgitation (FMR).
Patients undergoing Open Cardiac Surgery will be randomized into two groups. Group I will be ventilated with 40% Fio2 during induction, surgery and in Postoperative care unit. Group II will be ventilated with 100% Fio2 during induction and with 60-70% ( determined according to the arterial blood gas sample results) during surgery and in Postoperative care unit. Hemodynamic parameters ( systolic arterial pressure, diastolic arterial pressure, heart rate ), Arterial blood gas samples ( PaO2, PaCO2, pH, Oxygen saturation, Lactate), and pre and post cardiopulmonary bypass Superoxide dismutase and malonyl aldehyde levels.
