Mitroflow Heart Valve Failure | Device Alert

Sorin Mitroflow heart valves may prematurely deteriorate and become blocked, resulting in serious complications.  Device failure can lead to the need for early revision surgery, which comes with its own set of complications and risks. If you or a loved one has been affected, we can help – give us a call at 1.800.887.8029. We understand this may be a difficult time for you and your family, let us help you navigate the next steps.

What Is A Bioprosthetic Valve?

The Sorin Mitroflow is a bioprosthetic valve that is used to repair a damaged valve in patients with valvular heart disease. This type of heart valve is made from animal tissue and is often used in children born with congenital heart disease.  It allows surgeons to repair a heart valve in children and young adults until they are old enough to receive a more durable mechanical valve. Bioprosthetic valves are expected to be replaced after 8 years, but surgeons are noticing that the Mitroflow valve is failing much earlier – sometimes in less than two to three years after placement.

What is Aortic Valve Replacement?

According to the European Society of Cardiology, aortic valve replacement (AVR) is the most common heart valve operation performed today. Valve surgery is necessary when one of the four valves to the heart is not working, which can cause blockage in the blood flow. There are two types of replacement valves: mechanical and biological. Mechanical is composed of durable metals like pyrolitic carbon and titanium, while biological is made from animal tissue.

Heart Failure and Medical Studies

In a study recently published for the American Heart Association, physicians concluded that early structural valve deterioration (SVD) is frequent with the Mitroflow bioprosthesis model LX, especially for patients with smaller aortas. A revision surgery may be necessary in patients with severe SVD even if patients do not exhibit any symptoms, yet. Surgeons at Boston Children’s Hospital reportedly reached out to all patients who had the Sorin Mitroflow valve implanted and warned them to be tested for earlier than expected signs of failure.
