Autoimmune Basis for Postural Tachycardia Syndrome

Postural tachycardia syndrome (POTS) is a debilitating disorder resulting from cardiovascular autonomic dysfunction, has many causes and is very difficult to treat effectively. The investigators have identified the presence of autoantibodies (immune proteins) directed against some receptors of the autonomic nervous system that can cause patient's symptoms on standing. The ...

Safety and Performance of the Trialign Percutaneous Tricuspid Valve Annuloplasty System (PTVAS)

A prospective, single-arm, multi-center study, enrolling symptomatic patients with chronic functional tricuspid regurgitation. The study will include up to 60 subjects from up to 15 sites in Europe and the United States. Follow-up evaluations will be conducted through 5 years post implantation.

Stroke-free Survival Comparison Between Early Surgery and Conventional Therapy in Left Infective Endocarditis

Infective endocarditis (IE) is a relatively rare disease and has a high in-hospital mortality (15-30%) and morbidity due to complications like embolic events, especially in the central nervous system, and heart failure. International guidelines give indications on the optimal timing for surgery, and they strongly recommend early surgery for patients ...

Phase N/A

MitraClip and Hemodynamic Effects of Relevant Iatrogenic Atrial Septum Defect Closure

Transcatheter mitral valve repair with the MitraClip system is a therapeutic alternative to surgery in selected high-risk patients. Clip placement requires interatrial transseptal puncture and meticulous manipulation of the steerable sheath. There is evidence that the persistence of a relevant iASD after MitraClip is associated with worse clinical outcomes and ...

Phase N/A

Effect of Dexmedetomidine on Postoperative Renal Function in Infective Endocarditis Patients Undergoing Open Heart Surgery

Acute kidney injury is major complication after open heart surgery. The cause of acute kidney injury following open heart surgery is related to activation of sympathetic nervous system, decrease of renal blood flow, ischemia-reperfusion injury and systemic inflammatory response. Infective endocarditis patients undergoing open heart surgery have systemic inflammatory response ...

Phase N/A

A Trial of Genotype-based Warfarin Initiation in Patients With Mechanical Prosthetic Heart Valve

Until very recently, warfarin is still the best drug of choice for long-term anticoagulation for patients with mechanical prosthetic heart valve. However, the complication of warfarin account for 75 percent of the whole complication after the mechanical prosthetic heart valve replacement. Interindividual variation in warfarin dose is mediated by multiple ...

Clinical Metagenomics of Infective Endocarditis

Background and Rationale Infective endocarditis (IE) is an infection of cardiac valves. IE mainly involves bacteria, more rarely fungi. IE is an uncommon diseases with an estimated incidence of 1-12 cases per 100,000 inhabitants per year. The diagnostic of IE relies on the collection of biological samples (blood cultures and ...

Phase N/A

Impact of Clinical Care Pathway on Prognosis and Therapeutic Medical Care of Infective Endocarditis

Infective endocarditis (IE) is defined as a bacterial infection of the endocardium (inner surface of the heart), which may include one or more heart valves. Epidemiologic pattern has changed during the last 20 years whereas the incidence was unchanged. However, the mortality increase despite recent diagnosis and therapeutic advances. Only ...

Phase N/A

On-X Heart Valve - 17mm Aortic and 23mm Mitral

The purpose of the study is to assess the safety and efficacy of the 17mm On-X Aortic Prosthetic Heart Valve and the 23mm On-X Mitral Prosthetic Heart Valve when used to replace diseased aortic or mitral valves in human subjects. The On-X 17mm aortic and 23mm mitral valves will be ...

Registry to Gather Long-time Results After Surgical Aortic Valve Replacement With a "Rapid Deployment Aortic Valve Prothesis (Edwards Intuity) Combined With Bypss Surgery (CABG)

Aortic replacement combined with coronary bypass surgery has an impact on the risk profile for the direct postoperative course and also on the long-time survival perspective. The advantage of rapid deployment aortic valve prostheses, like the Edward Intuity Elite Valve that is used in this registry, is the greater ease ...
