Rheumatic heart disease remains a major health problem in developing countries. It is the most important sequel of rheumatic fever and occurs in about 30% of patients with rheumatic fever.Rheumatic heart disease presents with different degrees of pancarditis and associated valve failure. Involvement of the mitral leaflets can cause mitral regurgitation (MR) or stenosis and eventually can lead to heart failure. Mitral repair or replacement is therefore recommended before left ve...
Multicentre, double-armed, randomized controlled trial designed to compare mitral valve leaflet resection versus leaflet preservation with regards to the development of functional mitral stenosis following surgical repair of mitral valve prolapse. Patients will be randomized (1:1) to receive: (1) mitral valve repair with a leaflet resection or (2) mitral valve repair with leaflet preservation (using polytetrafluoroethylene neochordae), followed by echocardiographic and clinical...
In this retrospective cohort study, out of 220 patients who had undergone successful PTMC between 2006 and 2018, the clinical course of 186 patients could be successfully followed. Peri-procedural clinical and echocardiographic data were collected for these patients. Cardiac-related death, undergoing a second PTMC or mitral valve replacement (MVR) were considered adverse cardiac events in follow-up for the purpose of this study. Patients with no history of these events were con...
Primary mitral regurgitation (MR) is the second most frequent valve disease requiring surgery and it is important to identify patients whose outcome could be improved with surgery by considering the risks and benefits. The current guidelines recommend surgery in patients with symptomatic severe mitral regurgitation or in asymptomatic patients who develop early signs of left ventricular (LV) dysfunction as a result of the MR. However, it remains difficult to determine op...
The purpose of this study is to establish the safety and feasibility of the Edwards SAPIEN 3 valve in subjects with mitral annular calcification (MAC) associated with mitral stenosis (MS) and/or mitral regurgitation who are at high-risk for mitral valve surgery or deemed inoperable due to the extent of calcification.
Aortic stenosis is a major cause of morbidity around the world. Progressive aortic stenosis leads to cardiac hypertrophy as a compensatory response. A maladaptive response may lead to heart failure at varying degrees of severity of aortic stenosis in individual patients. The predicting factors for the occurrence of a maladaptive response are not well defined. Therefore current medical therapy for aortic stenosis is considered insufficient and may actually cause harm. The only e...
- Chronic severe mitral regurgitation can lead to symptoms and left ventricular dysfunction. - The purpose of this study is to prospectively follow patients with non-ischaemic cardiomyopathy who are eligible for mitral valve repair surgery and primarily measure the quality of life through the Minnesota Living with Heart Failure Questionnaire & the Kansas City Cardiomyopathy Questionnaire.
The PREPARE-MVR (PRediction of Early PostoperAtive Right vEntricular failure in Mitral Valve Replacement/Repair patients) Study aims to evaluate those preoperative factors which can predict the early postoperative right ventricular failure or determine the functional shift seen in right ventricular function after mitral valve replacement/repair. The PREPARE-MVR study focuses mainly on echocardiographic (both conventional and advanced) parameters and includes right heart cathete...
To demonstrate that the Conveyor System can safely provide left ventricular access to deliver the SAPIEN 3 (Edwards Lifesciences, Irvine, California) transcatheter heart valve in patients who have been diagnosed with prior mitral valve replacement or repair (failing bioprosthetic mitral valve) who are candidates for mitral valve-in-valve procedure.
Our trial will be a randomized controlled trial and patients with moderate to severe mitral stenosis and atrial fibrillation will be included in the study. They will be divided into two groups differed by their anticoagulation therapy. Our intervention group will receive rivaroxaban and our control group will be treated by warfarin. All the patients will be observed closely in a period of one year. Through the follow up, embolic events and hemorrhagic complications will be reco...
The investigator hypothesize that High Spinal Anesthesia (HSA) by its effect on attenuation of stress response, decrease in pulmonary vascular resistance, myocardial protection and positive myocardial oxygen balance will cause improvement in right ventricular function. So far there is no study that has evaluated the effect of HSA anesthesia on the right ventricular function, hence the investigator planned this study to compare the effect of HSA on the right ventricular function...
To establish the correlation between echocardiographic parameters of the RV, measured with TEE and the right ventricular ejection fraction (thermodilution). To identify a time in the perioperative process when RV dysfunction occurs.
The aim of this study is to validate prospectively the predictive score of late results about a diverse population recruited in France and to evaluate the contribution in predicting the outcome of the PMC scanner to study the mitral calcium score and the location of the calcifications.
The purpose of this study is to assess the role of cardiac imaging combined with demographic, clinical, and biochemical parameters in predicting outcomes following percutaneous mitral valve intervention in order to facilitate more careful risk stratification, interventional planning and avoidance of high risk futile procedures.The principle objective of this study is to determine if transthoracic echocardiography (TTE) can predict changes in left ventricular (LV) size and funct...
The purpose of this pilot study is to evaluate the progression of ventricular dysfunction in patients with ventricular dysfunction within the permanent pacing population.
The aim of this study is i) to evaluate left ventricular global longitudinal strain and myocardial work in patients with heart failure and severe functional mitral regurgitation one year after MitraClip implantation and compare these variables with patients treated with optimal medical treatment and ii) to find echocardiographic predictors of clinical response and reverse left ventricular remodeling at one-year follow up.
The efficacy and safety of anticoagulation therapy using dabigatran in comparison with warfarin will be evaluated in patients with atrial fibrillation after mitral valve prosthetic replacement concomitant with Cox-Maze procedure.
Impairment of relaxation, the early phase of ventricular diastole is the first stage of heart diastolic dysfunction. Left ventricular diastolic function can be determined noninvasively by Echo- Doppler – derived mitral valve flow velocities. The addition of pulmonary venous flow pattern enables more accurate assessment of left ventricle diastolic function. The role of the right ventricle in haemodynamic function of the heart is now emphasized. The right ventricle diastolic f...
The purpose of this study is to study the effect of Ivabradine vs Atenolol on heart rate and effort tolerance in patients with mild to moderate mitral stenosis and normal sinus rhythm.
This preliminary study will compare the effectiveness of two-dimensional and three-dimensional echocardiographic measurements of wall thickness and left ventricular mass in patients with Aortic Stenosis
This study evaluates the addition of transcatheter mitral valve repair with the MitraClip device to medical treatment in patients with heart failure and moderate functional mitral regurgitation to determine the impact of left ventricular remodelling and patients' functional capacity.
The study compares the effectiveness of treatment with MitraClip to medical therapy in improving the reduction of cardiovascular morbidity and functional capacity at 12 months, in patients with moderate functional mitral regurgitation.
