Neovasc Reducer - Treatment of Refractory Angina and Tiara System
Neovasc is focused on creating better outcomes for difficult-to-treat cardiology patients through the development of two novel products: Reducer™* for treatment of refractory angina and the Tiara™ System* for treatment of mitral valve regurgitation. Millions of patients worldwide with coronary artery disease who are not candidates for revascularization suffer from refractory angina despite receiving optimal medical therapy.
Product Details
Before Neovasc’s Reducer,* there were limited real options for treating refractory angina. Reducer is a small, balloon-expandable, hourglass-shaped device that establishes a narrowing in the coronary sinus. The resulting increase in back pressure redistributes blood into the ischemic myocardium.
Reducer is CE-marked in Europe and has been implanted in over 2,000 patients. It is currently under clinical investigation in the US.
Novel Mitral Valve Replacement System
Neovasc is developing the Tiara™ System* for the treatment of severe mitral valve regurgitation (MR), a condition that affects approximately four million patients in the U.S. alone. Currently, conventional surgical treatments are only appropriate for about 20% of these patients, leaving the majority of patients untreated.
The Tiara device is delivered through the apex of the heart to replace the mitral valve while preserving the integrity of the surrounding structures of the heart. Tiara has been designed specifically to address the myriad of challenges inherent to the treatment of MR, as well as meeting the need for transcatheter replacement of the mitral valve. Tiara implantation is achieved through a transapical approach and does not typically require any hemodynamic support
What Is Refractory Angina?
Angina is a type of chest pain, usually a symptom of coronary artery disease (CAD). CAD happens when plaque build-up occurs in the arteries supplying oxygen-rich blood to the heart, forcing the heart to work harder. This is what produces the painful angina, which may feel like pressure or squeezing in the chest, or pain in the shoulders, arms, neck, jaw or back.
Of all patients experiencing angina, it is estimated that about 10%¹ suffer symptoms that are severe, long lasting, and cannot be controlled by traditional medical therapies. This severely debilitating condition is known as refractory angina.
Prior to the Reducer System there were few, if any, real options for treating chronic refractory angina.
The Reducer* is a small, hourglass shaped device implanted in the coronary sinus, a collection of veins joined together to form a large vessel that collects blood from the heart muscle. The device creates back pressure within the coronary sinus that increases the flow of oxygen-rich blood to areas of the heart that previously did not have normal blood flow.
The Reducer Device is approved for use in many countries and has been successfully implanted in thousands of patients internationally. The long-term results of Reducer therapy continue to be studied. As with any medical procedure, there are risks associated with the use of the Neovasc Reducer. For a complete list of potential risks and benefits, ask your doctor.
Doctors place the device using a minimally invasive procedure, usually performed under local anesthesia. Most patients are discharged within 24 hours. Relief varies by patient and depends on a number of factors, but some patients report relief from angina symptoms as early as six weeks after the procedure, with most patients reporting improvement within three months.
