Filter by:To evaluate the efficacy and safety of the transcatheter tricuspid valve ring system produced by Shanghai Huihe Medical Technology Co., Ltd. in the treatment of patients with severe or above tricuspid regurgitation who cannot be evaluated by clinicians for surgery.
The Mistral is an investigational device intended for percutaneous trans-catheter repair in high risk for surgery individuals suffering from functional Tricuspid Regurgitation (TR). The device system is to be used only in accordance with the approved Investigational Plan on subjects who have signed an informed consent form. Device use is limited to the approved study investigators.
A prospective, open, non-randomized, multicenter, clinical trial to evaluate the safety and effectiveness of the Edwards EWJ-202 transcatheter tricuspid valve replacement system in the treatment of patients with at least severe tricuspid regurgitation despite medical therapy. Subjects will be followed at discharge, 30 days, 6 months and annually through 5 years.
1050 patients with persistent/permanent atrial fibrillation (AF) will be studied using conventional and advanced (three-dimensional and deformation imaging) echocardiography. Patients with moderate/severe isolated secondary tricuspid regurgitation (STR) will undergo blood tests to assess their proteomic profile and cardiac CT to measure the tricuspid annulus geometry. The project will aim to 1. assess the prevalence of moderate/severe isolated STR in patients with AF; 2. identify the mechanisms associated with the development of moderate-severe STR in patients with AF; 3. identify the proteomic profile associated with significant growth of tricuspid valve leaflets as a mechanism to protect patients with AF from the development of moderate/severe STR; 4. evaluate the effects of the restoration of sinus rhythm on the severity of STR and the remodeling of the right heart cardiac structures (i.e. right ventricle, right atrium, and tricuspid valve apparatus).
The aims of this study are: 1. to explore a novel 2D-Cardiovascular magnetic resonance (CMR) indirect method for tricuspid regurgitation (TR) quantification (ATRIAL method) relying on right atrium variables, and assess its agreement with the traditional indirect method (involving right ventricle variables) and the direct method (based on through-plane phase contrast (PC) sequences on the tricuspid valve); 2. to assess the agreement of TR volume (RVol) and regurgitant fraction quantification from 2D-CMR methods with transthoracic echocardiography and 4DF-CMR methods; 3. to assess the diagnostic performance of 2D-CMR in classifying TR, in terms of RVol and regurgitant fraction, with respect to echocardiographic transthoracic echocardiography grades.
Prospective, multicenter, observational study to enroll consecutive patients with functional tricuspid regurgitation (FTR) with the primary aim to: - Use patients' outcomes as a reference to try to define the threshold values for the different grades of FTR severity; and secondary aims to: - Use 3D echocardiography to assess the relationships among the geometry (size and shape) of the right ventricle, right atrium, tricuspid annulus, and tricuspid leaflets according to the underlying cardiac condition (i.e., atrial fibrillation, pulmonary hypertension, right ventricular cardiomyopathy, congenital heart diseases, etc.) - Assess the accuracy, and incremental diagnostic and prognostic value of a new software package to measure tricuspid annulus and valve geometry - Develop new parameters of FTR severity that take into account the lower momentum of the tricuspid regurgitant jet (compared with the mitral regurgitation jet), the complex anatomy of the regurgitant orifice, and both the intra-beat and respiratory variation of the regurgitant volume - Test the hypothesis that there is no actual grading but a continuum of increased risk of adverse outcome with the increase of FTR severity, and we need robust quantitative metrics (for example, the regurgitant fraction - currently not included in guidelines - which takes into account the right ventricular volume and function) more than grading schemes to assess the severity of the diseases and the effect of treatments - Test the hypothesis that the relationship between FTR severity and the outcome may be different according to the underlying cardiac condition (i.e., atrial fibrillation, pulmonary hypertension, right ventricular cardiomyopathy, congenital heart diseases, post-cardiac surgery, etc.) as this will affect the timing for interventions
The goal of this pivotal study is to demonstrate the safety and performance of the Cor TRICUSPID ECM (extracellular matrix) Valve (or Cor PEDIATRIC Tricuspid ECM Valve) for the surgical management of tricuspid valve disease and dysfunction in adult and pediatric patients. The main question(s) it aims to answer are: - whether the device may be implanted successfully and safely, and - whether the device effectively treats tricuspid valve disease and dysfunction through 12 months Participants will undergo: - preoperative evaluation - tricuspid valve replacement with the Cor TRICUSPID ECM Valve - postoperative evaluation, including at hospital discharge, 30 days, 6 months, and 12 months, and then annually thereafter through 5 years
The aim of our study is to investigate the molecular mechanisms underlying remodeling of the tricuspid valve apparatus in patients with ITF and isolated AF, in comparison with patients with ITF from right ventricular remodeling, patients with atriogenic MI and left ventricular remodeling. To achieve these aims, markers obtained from cardiovascular imaging methods, such as 3D echocardiogram, and biomarkers isolated from the peripheral blood of the study participants will be considered.
Tricuspid regurgitation (TR) was identified as an independent prognostic factor associated with excess mortality and morbidity, independent of left ventricular (LV) function and pulmonary hypertension. Isolated tricuspid surgery has been performed for a long time in a few selected cases, however in recent years several studies have underlined how the poor outcomes described for isolated tricuspid valve surgery seem to be related to the baseline characteristics of the patients and to late referral for surgical treatment rather than the intervention itself. To facilitate patient screening, a new clinical and functional TR staging system has recently been proposed. This classification, which evaluates the progression of morphological variations of the tricuspid valve and right ventricle (RV) in association with the onset of symptoms, identifies several parameters and factors that can be useful for a better stratification of surgical risk. Rather than simply assessing the degree of TR, this new staging mechanism also focuses on symptoms, RV remodeling and function, medical therapy, and right heart failure hospitalizations. Investigators previously focused on the short-term (mainly hospital) outcomes of patients undergoing isolated surgery for severe TR, who were classified at baseline according to this clinical and functional staging system. Results showed that a more comprehensive classification reflects the population and hospital outcomes of surgically treated patients with isolated TR. The purpose of this study is to ultimately evaluate long-term outcomes of this patients population and estimate the impact of baseline staging on long-term outcomes.
The purpose of this study to identify the efficacy of sodium glucose cotransporter 2 inhibitors add-on treatment on right ventricular remodeling and the amount of severe tricuspid regurgitation (TR) in patients with isolated severe TR.
