Filter by:The purpose of this study is to compare cardiac output results obtained using the thermodilution push technique with the Pulmonary Arterial Catheter (PAC) to the predicted cardiac output results obtained from the non-invasive FloWave™ 1000 device.
The purpose of this study is to further evaluate the long-term safety and effectiveness of the Biocor and Biocor Supra Valves.
Mitral regurgitation (MR) is common in the elderly and its prevalence is increasing with the aging of the population. Organic MR, due to primary valvular lesions, initiates a cascade of complications determined by its degree. MR of severe degree is associated with excess mortality and high cardiac morbidity (heart failure, atrial fibrillation). It also causes left ventricular remodeling which induces left ventricular dysfunction, which in turn leads to poor clinical outcome. Surgery can eliminate MR, but carries immediate and long-term risks, especially in the elderly. Therefore, chronically decreasing the degree of MR is a major goal of medical therapy but such an effect is yet unproved because of conflicting results of small and mostly non-randomized series. Our recent preliminary studies suggest that a sustained decrease of degree of MR and improvement of left ventricular remodeling can be achieved with powerful reduction of afterload, obtained in particular with angiotensin-II receptor blockade. Therefore, the present proposal seeks to address gaps of knowledge regarding vasoactive treatment of MR through the verification of the following hypothesis: Hypothesis: Vasoactive therapy using angiotensin-II receptor blocker (Candesartan Cilexetil) weighed against placebo produces a sustained reduction of the consequences of organic MR. The specific aims are that the treatment a) decreases the degree of MR (decreases the regurgitant volume, primary end-point) and b) improves left ventricular remodeling (decreases the end-diastolic volume index, secondary end-point), as compared to placebo.
Improvement in heart failure with moderate to severe mitral regurgitation using a percutaneously delivered implanted device
Reduction in mitral regurgitation due to safe placement of a PTMA device in the coronary sinus.
Improvement of heart failure with moderate to severe mitral regurgitation using a percutaneously delivered implanted device.
The purpose of this study is to collect data on the effectiveness and clinical outcomes of the MEMO 3D Annuloplasty ring as used for mitral valve repair.
Evaluation of the technical feasibility and safety of the Mitral Adjustable Annuloplasty Ring.
Mitral valve repair for ischemic mitral regurgitation is performed primarily by annuloplasty. There is some degree of late failure, which may be due in part to the type of ring employed. We want to compare late results with mitral valve annuloplasty using flexible vs rigid annuloplasty rings.
The purpose of this study is to evaluate the effect of a single dose of etomidate for patients undergoing cardiac surgery with the use of cardiopulmonary bypass (CPB) on post-CPB adrenocortical responsiveness, on requirements of hemodynamic support, and on use of intensive care resources.
