Cardiovascular Disease

There are many different forms of cardiovascular (heart) disease.  The most common cause of cardiovascular disease is narrowing or blockage of the coronary arteries, the blood vessels that supply blood to the heart itself.  This is called coronary artery disease and happens slowly over time.  Other kinds of heart problems may happen to the valves in the heart, or the heart may not pump well and cause heart failure.  Some people are born with cardiovascular disease.

Transcatheter Aortic Valve Replacement to UNload the Left ventricle in patients with ADvanced heart failure: a randomized trial  (TAVR UNLOAD)

The TAVR UNLOAD trial is an international, multi-center, randomized, open-label, clinical trial comparing the safety and efficacy of Transcatheter Aortic Valve Replacement (TAVR) with the SAPIEN 3 Valve and optimized heart failure therapy ( OHFT ) versus OHFT in heart failure (HF) patients, with moderate aortic stenosis ( AS). OHFT is defined as guideline-directed medical therapy. It can be medication only or a combination of medical therapy and approved HF devices.

Clinical efficacy of TAVR is assessed after 1 year of follow-up in all 600 patients. All patients are followed for 2 years to evaluate the value of the study device in to treat patients with Heart Failure (HF) who have moderate aortic stenosis (AS). The Edwards SAPIEN 3 Valve has already been approved by the FDA for use in patients who require an aortic valve replacement due to severe aortic stenosis

Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (The COAPT)

This is a study to evaluate the safety and effectiveness of the MitraClip System for the treatment of moderate-to-severe or severe functional mitral regurgitation (FMR) in symptomatic heart failure subjects who are treated per standard of care and who have been determined by the site’s local heart team as not appropriate for mitral valve surgery. Eligible subjects will be randomized in a 1:1 ratio to the MitraClip device (Device group) or to no MitraClip device (Control group). Approximately 610 subjects will be randomized with approximately 305 subjects targeted to receive the study device.
