Filter by:Mitral regurgitation (MR) and tricuspid regurgitation (TR) are common causes of breathlessness, fluid retention and other heart failure symptoms, which lead to reduced quality of life and frequent hospitalisation. These conditions are particularly prevalent in older adults with many of these patients being at high risk for surgical intervention due to frailty and comorbidities, leaving them with few treatment alternatives. Transcatheter edge-to-edge repair (TEER) procedures have increasingly been used to improve the severity of both MR and TR, offering patients symptomatic relief and reductions in heart failure hospitalisation at low procedural risk. There is considerable geographic variation in protocols to assess these patients prior to the procedure and also in length of hospital stay. The standard of care in the UK, and particularly in Oxford, emphasises fewer investigations before the TEER procedure and shorter length of hospital stay. This prospective, observational cohort study will examine the safety and feasibility of this practice.
This observational study is to develop and validate the prediction model for functional mitral regurgitation regression in heart failure patients taking GDMT. The patients diagnosed ≥2+ functional mitral regurgitation by ultrasonic cardiogram are enrolled in this study and would be clinically followed by at least one year (clinical visit at 3 months, 6 months, and 12 months), and then by when the endpoints are reached.
To investigate to assess the severity of mitral regurgitation by multimodality imaging.
Study objectives: - To assess the impact of mitral valve surgery for mitral regurgitation on ventricular arrhythmic burden and surrogate markers of fibrosis in patients with arrhytmogenic mitral valve prolapse (MVP) from baseline to 6 months after surgery - To characterize the molecular landscape of arrhytmogenic MVP Study design: -Prospective explorative observational study Study population: -90 patients with arrhytmogenic MVP and without arrhytmogenic MVP (controls) eligible for mitral valve surgery for mitral regurgitation will be enrolled. All patients will be evaluated with cardiac magnetic resonance (CMR) imaging and continuous seven day arrhythmic monitoring before and at 6 months after mitral valve surgery
The aim of PLUTO-II is to use biventricular pressure-volume (PV) loop measurements to improve the understanding of direct changes in cardiac and hemodynamic physiology induced by transcatheter aortic valve implantation (TAVI) or tricuspid edge-to-edge repair (TEER). These procedures evoke immediate changes in cardiac mechanoenergetics, ventricular-vascular interaction as well as ventricular (in)dependency. Within the context of PLUTO-II, patients will undergo biventricular PV-loop measurements before and after TAVI or TEER. In future, the application of perprocedural PV loop monitoring may tailor the daily individual decision making process during structural interventions in the catheterization laboratory.
Quantification of residual mitral regurgitation (MR) after MitraClip may be challenging. Quantitative methods for severity assessment may be inaccurate and recent recommendations suggest an assessment of changes in both hemodynamic and echocardiographic parameters, but an established prospectively validated approach is still lacking.
To investigate the efficacy and safety of transcatheter mitral valve edge-to-edge repair (TEER) for severe degenerative mitral regurgitation (DMR) patients of low to intermediate surgery risk.
This study will assess hemodynamic changes induced after spinal anesthesia by evaluating vasopressor inotropic requirements and variations in echocardiographic parameters in patients having severe aortic stenosis or severe mitral regurgitation undergoing aortic or mitral valve replacement surgery.
To study echocardiography splay sign in mitral regurgitation and its association with mitral regurgitation severity and doppler band artifact ('seagull cry').
The goal of this observational study is to compare the safety and effectiveness of a modified drug therapy with traditional drug therapy in pediatric patients after mitral repair. The main questions it aims to answer are: - Can a modified drug therapy improve both left ventricular and mitral valve function in pediatric patients after mitral repair? - Can the adverse drug reactions caused by the modified drug therapy be non-inferior (clinically acceptable) to those of the traditional drug therapy? Participants will be assigned to either the Modified Drug Therapy Group (comprising angiotensin-converting enzyme inhibitor (ACE-I), beta-blockers, diuretics, potassium supplements, and spironolactone) or the Traditional Drug Therapy Group (diuretics and potassium supplements) based on personal preferences and clinical assessments by their attending physicians. They will undergo a 6-months course of medication. Additionally, echocardiography, electrocardiograms, complete blood counts, biochemical tests, and measurements of N-terminal pro-brain natriuretic peptide (NT-proBNP) were conducted before the initiation of medication therapy and at 1 month, 3 months, and 6 months after treatment commencement. Researchers will compare the Modified Drug Therapy Group and the Traditional Drug Therapy Group to see if the recurrence rate of moderate to severe mitral valve regurgitation, as assessed by echocardiography after 6 months of treatment, is lower in the former than in the latter.
