Active clinical trials for "Heart Valve Diseases"

The aim of this randomized controlled trial to investigate the effects of Real-time 3D transesophageal echocardiography (RT3D-TEE)-guided mitral valve repair on surgical failure and 1-year reoccurrence of mitral valve regurgitation in patients with degenerative mitral value disease.

Acute gastrointestinal injury (AGI) is related to poor outcomes in patients after heart valve replacement. The purpose of this study is to evaluate the effect of the probiotic mixture supplementation (PMS) in patients after heart valve replacement by preventing acute gastrointestinal injury (AGI).

Valvular heart disease (VHD) is a growing and important public health problem due to the increasing prevalence of degenerative VHD, accompanied by prolonged life expectancy in developed countries. It is associated with high morbidity and mortality.Heart valve surgery is one of the proven treatments of VHD, which corrects hemodynamic abnormalities that could contribute to decrease mortality and improvement in quality of life, despite the improvement in the hemodynamic parameters, the cardiorespiratory fitness level remained low after heart valve surgery. Cardiac surgeries can cause a series of clinical and functional complication. Postoperative pulmonary complications are the most common, in turn, contribute directly to increase morbidity and mortality and longer hospital stays.Mucociliary clearance is affected after open-heart surgery by the effects of general anaesthesia, intubation and analgesia. Expiratory flow rate is directly related to lung volume and therefore when lung volumes are decreased, coughing will be less effective. Chest physical therapy plays an important role in the prevention and management of postoperative pulmonary complications. It includes deep breathing exercises, mobilization, postural drainage, percussion and vibration or shaking which were developed to improve bronchial drainage. Airway clearance techniques are commonly used for clearing secretions, improving gas exchange, oxygenation, and work of breathing. Acapella® is an airway clearance device that combines the resistive features of a positive expiratory pressure device with oscillations which diminishes the mucus adhesiveness and decrease the collapsibility of airways. In the present study, the aim is to compare the effect of acapella and incentive spirometer on cardiopulmonary fitness in patients undergoing heart valve surgery. Those patients may gain a more benefit from acapella application and incentive spirometer so, prevent post-operative pulmonary complication, reduce hospitalization and hospital costs, and improve quality of life. Therefore, early mobilization and chest physiotherapy including acapella and incentive will be started on 1st day after discharge from cardiac care unit (CCU) .

The objective of this prospective, randomized, blinded clinical trial is to assess the safety and efficacy of the Carillon Mitral Contour System in treating heart failure with functional regurgitation (FMR).

A prospective multicenter study enrolling high surgical risk patients with severe mitral annular calcification (MAC) and symptomatic mitral valve disease. There are 2 arms in this study: Transseptal Valve-in-MAC (ViMAC) and a control arm of patients treated with medical treatment only which will include patients who can't be treated due to the presence of anatomical exclusion criteria or other exclusion criteria.

Valvular heart diseases are among the most common cardiac pathologies in adult patients in Germany. Currently, the process of care before, during and after heart valve surgery does not follow a standardized and interdisciplinary optimal approach. An approach already established in other surgical disciplines is the Enhanced Recovery After Surgery (ERAS) protocol, which aims at optimizing the recovery process of patients. Within the INCREASE study, a care process inspired by the ERAS protocol will be established at the University Heart and Vascular Center (UHZ) of the University Medical Center Hamburg-Eppendorf (UKE) and the University Medical Center Augsburg (UKA). Executing the study at two facilities in different regions in Germany will help to demonstrate transferability of the process of care. The effectiveness of this process compared to the current treatment approach will be investigated in a randomized controlled trial. A total of 186 patients will be allocated by chance either to the intervention group (ERAS protocol) or the control group (treatment as usual). Patients in the intervention group will receive an optimized interdisciplinary care protocol including medical, nursing, physiotherapeutical and psychotherapeutical interventions. Measurements of effectiveness are the number of hospitalized days (due to cardiac causes) within one year and the physical condition of the patient as measured by the 6-minute walk test (6MWT) on the day of discharge.

The aim of this trial is to evaluate the safety and cost effectiveness of omission of percutaneous coronary intervention of significant coronary artery disease in patients scheduled to undergo transcatheter aortic valve implantation.

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.

The investigators are interested in determining the best surgical technique to correct functional mitral regurgitation, as there is currently not one technique that is established to work better than the other. The technique used in current clinical practice is undersizing mitral annuloplasty (UMA), in which a prosthetic ring is implanted onto the mitral valve to correct the leakage. Though widely adopted, durability of the repair is less, as 58% of the patients present with recurrent FMR within 2 years. There are no specific algorithms to predict who might have UMA failure, but research indicates that some geometric indices might be strong predictors. The investigators are interested in testing the hypothesis that, elevated lateral inter-papillary muscle separation (IPMS) is a predictor of post-UMA recurrence of FMR at 12 months. In the first part of this study, the study team will measure lateral IPMS before surgery, and relate to post-surgery FMR severity at discharge/30 days, 6 months and 12 months. A relatively newer technique is papillary muscle approximation (PMA), in which a suture draws together the two muscles that connect the mitral valve to the heart muscle prior to performing UMA. This reduces the lateral inter-papillary muscle separation (IPMS) and is expected to improve the durability of UMA. In the second part of this study, the investigators will perform PMA and UMA together and determine if FMR severity is reduced at discharge/30 days, 6 months and 12 months.
