Mitral Valve Repair
To speak with a mitral valve disease specialist, call 410-328-5842.
When performed correctly, patients who have undergone mitral valve repair see significant improvement. It is the only heart operation in which your life expectancy afterward is identical to someone with no heart disease.
Receiving care at a top valve program with skilled and experienced physicians directly impacts your likelihood of keeping your own valve and achieving a successful outcome. At the University of Maryland’s Heart Valve Program, you can expect:
In the past, surgeons simply replaced problematic mitral valves. While many centers still do this for a significant portion of cases, we have taken a different approach that allows the bulk of our patients to keep their valves.
Some examples of our surgical repair include:
- Sewing in a new ring of plastic, cloth or tissue to support the valve’s circular frame (the annulus)
- Trimming off the diseased portion of a valve flap (leaflet) and closing up the defect
- Reconstructing leaflets, then using sutures to support the valve
- Replacing a leaflet using tissue surrounding the heart (the pericardium)
When performed by top surgeons like ours, mitral valve repair is very successful. Approximately 90 percent of repaired valves are still working 20 years later, with just 10 percent of patients needing a second operation during that time.
Mitral valve repair also offers a number of clear benefits over replacement:
- Higher survival rates
- No long-term use of blood thinners (required if you get a mechanical replacement valve)
- Safer — lower risk of mortality, infection and stroke
Our mitral valve expertise extends to repairs of complex cases. These can include:
- Patients who previously underwent surgery for another heart-related problem like a blocked artery and subsequently need a mitral valve repair
- A repaired valve developing a new leak due to a cause like infection
- Valves that were not properly repaired at another center
These cases require skilled surgeons because the valve is often surrounded by scar tissue that naturally develops as the body heals from previous operations. Follow-up operations are also challenging when patients are elderly, in poor health for other reasons or have poor heart function.
We lead the way in minimally invasive mitral valve repair. We performed Maryland’s first catheter-based repair, and we also completed the mid-Atlantic’s first surgical repair using a minimally invasive approach.
We offer two types of minimally invasive mitral valve repair, for separate reasons:
- Patients who cannot undergo an operation: We offer catheter-based repair for patients with leaky valves (regurgitation), as an approved treatment or through a clinical trial. That means we do not have to open the chest or use a heart-lung machine. (Learn more about transcatheter mitral valve repair.) We can also open some narrowed mitral valves with a catheter and a balloon. (Learn more about valvuloplasty.)
- Patients who prefer a smaller incision: Some of our patients who are eligible for surgery prefer smaller incisions, made on the side of the chest. While the standard approach is very successful, we try to honor this request when possible. But sometimes we cannot, since we need to prioritize your health and valve function. This type of minimally invasive surgery still requires a heart-lung machine, which temporarily takes over for the heart and lungs.
