View clinical trials related to Mitral Valve Insufficiency.
Filter by:an international multicentre registry designed to answer 3 clinical questions: 1. Describing the characteristics and outcomes of current patients undergoing aortic + mitral transcatheter heart valve procedures. 2. Better understanding of the predictors for MR regression following isolated TAVI and consequently estimating the fraction of patients who will be suitable for TMVR/r post TAVI 3. Examining the clinical outcomes of patients with significant MR post TAVI who subsequently underwent TMVR/r compared to those left for medical management.
to evaluate the safety and performance of the HighLife 28mm transcatheter, trans-septal Mitral Valve in patients with moderate-severe or severe mitral regurgitation who are at high risk for surgical treatment.
Study to evaluate the feasibility, safety and performance of the HighLife trans-septal Transcatheter Mitral Valve in patients with moderate-severe and severe mitral regurgitation who are at high risk for surgical treatment.
Comparison patients with CABG alone vs. CABG+mitral surgery with non-massive ischaemic mitral regurgitation (IMR) depending on stress echo data.
To evaluate whether patients after successful transfemoral transcatheter aortic valve implantation (TAVI), who have concomitant, moderate to severe mitral regurgitation (MR) benefit from an additional treatment of this valve disease as well.
The study evaluates the long-term results of patients affected by bileaflet prolapse in Barlow's Disease, treated with edge-to-edge technique between 1997 and 2011.
Prospective, single-arm, multicenter study to evaluate the safety and performance of the AltaValve for the treatment of moderate to severe or severe mitral valve regurgitation in subjects who are considered high risk for mortality and morbidity from conventional open-heart surgery.
Transcatheter mitral valve repair in the form of MitraClip® is a safe and effective alternative to surgical mitral valve repair/replacement in patients with high operative morbidity and mortality risk. Successful MitraClip application depends on intraprocedural quantification of mitral regurgitation and left atrial pressure (LAP) monitoring. The pleth variability index (PVI) is a noninvasive, dynamic index based on analysis of the respiratory variations in the plethysmographic waveform recorded transcutaneously by the pulse oximeter. Studies demonstrate that PVI is accurate in predicting fluid responsiveness in mechanically ventilated adult patients. In this study, we wish to measure PVI during TMVR and correlate with invasive indices such as left atrial pressure (LAP) and stroke volume variation. Our study hopes to provide a real-time non-invasive alternative to invasive indices to better guide fluid management and improve hemodynamics.
To assess the safety and performance of the Cephea Transseptal Mitral Valve System for the treatment of symptomatic moderate to severe degenerative or functional mitral regurgitation, in patients who are poor candidates for surgery.
Secondary mitral insufficiency is a common complication of heart failure, aggravating symptoms and prognosis, and may be responsible for worsening dyspnea, pulmonary edema, and excess mortality. It is essentially a ventricular rather than a valvular disease, whose origin may be ischemic or not. It is induced by a geometrical and contractile modification of the left ventricle which causes an imbalance between the tensile and the closing forces of the mitral valve thus causing a defect of coaptation and the increase of the surface between the mitral leaves and the ring in systole (tenting). Dynamic mitral insufficiency is defined by changes in the degree of severity of regurgitation as a function of hemodynamic conditions. During exercise, the course of mitral insufficiency is variable and is not predicted by the degree of regurgitation at rest. The worsening of the leak is also well correlated with the onset of dyspnea on exertion in patients with left Ventricular Ejection Fraction heart failure (LVEF reduced). Nevertheless, there is little data available in the literature on the factors predisposing to the development of stress-related mitral insufficiency, as well as its clinical and echocardiographic impact in the cardiac insufficiency patient, particularly in the case of preserved LVEF (6.7%). The identification of echocardiographic data at rest to predict and anticipate the behavior of mitral insufficiency in the effort (aggravation or stability / disappearance), would allow a simplified evaluation and a better management in this population of patients for which the evaluation in echography of effort can be technically complex and limited (difficulty of quantification of the mitral leak, time of effort sometimes too short ...).
