The mitral valve controls blood flow between the upper left heart chamber (atrium) and the lower left heart chamber (ventricle). The most common conditions that result in a mitral valve that fails to function properly are:
Mitral valve regurgitation, a leaky mitral valve, which can cause irregular heart rhythms or heart failure.
Mitral valve stenosis, a narrowed mitral valve, which can cause pressure buildup in the left atrium.
What is TMVR?
Heart valve disease is a serious health condition that affects millions worldwide. Among the valves, the mitral valve plays a critical role in maintaining proper blood flow from the left atrium to the left ventricle.
Transcatheter Mitral Valve Replacement (TMVR) is a minimally invasive procedure designed to replace a damaged or diseased mitral valve in the heart. Unlike traditional open-heart surgery, TMVR uses catheters inserted through small incisions, typically in the groin, to deliver and implant a new valve.
Who Can Benefit from TMVR?
TMVR is particularly beneficial for patients deemed too high-risk for conventional surgery due to age, illness, or other complicating factors.This includes individuals with mitral valve regurgitation (leaking) or mitral valve stenosis (narrowing) who experience symptoms such as shortness of breath, fatigue, or heart palpitations.
What is a Mitral Valve-in-Valve procedure?
Valve-in-valve implantation is a cutting-edge procedure performed using a catheter-based technique, similar to TAVR and TMVR. Instead of removing an already implanted failed surgical bioprosthetic valve, a new valve is inserted within the existing one through a catheter. We place a new valve to treat a failing ring (small, mesh band that reinforces the mitral valve) from a prior surgery or to replace a failing prosthetic replacement valve.
This procedure significantly reduces recovery time and the risks associated with open-heart surgery, making it a preferred option for high-risk patients, particularly the elderly or those with multiple health issues.
What are the advantages of TMVR?
Minimally Invasive
Faster Recovery
Less pain
Suitable for high risk patients
Frequently Asked Questions
What is Transcatheter Mitral Valve Replacement?
TMVR is a catheter-based procedure that replaces a diseased mitral valve without the need for open-heart surgery.
Why is TMVR performed?
It is performed to treat severe mitral valve disease in patients who are not suitable candidates for surgical valve replacement.
When is TMVR recommended?
TMVR is recommended when mitral valve disease is severe, symptoms persist despite medical treatment, and surgical risk is considered high.
Is TMVR a safe procedure?
When performed in specialized centers with experienced teams, TMVR is considered a safe and effective minimally invasive treatment option.
