MitraClip / TEER for Leaky Mitral Valve: Minimally Invasive Treatment for Mitral Regurgitation in India
Breathlessness is not always because of lung disease. Tiredness is not always due to age. Swelling in the legs, difficulty lying flat, repeated hospital visits for heart failure, or unexplained fatigue can sometimes point to a leaky mitral valve, medically known as mitral regurgitation.
In mitral regurgitation, the mitral valve does not close properly, allowing blood to leak backward inside the heart. Mild leakage may not cause symptoms, but as the leak becomes severe, patients may develop breathlessness, fatigue, palpitations, swelling of the legs, or worsening heart failure symptoms.
For many years, severe mitral valve leakage was mainly treated with open heart surgery. Today, selected patients may be suitable for a less invasive treatment called MitraClip or TEER — Transcatheter Edge-to-Edge Repair.
This treatment is especially important for elderly patients, high-risk patients, patients with weak heart function, or those who may not be ideal candidates for conventional open heart surgery.
What Is a Leaky Mitral Valve?
The mitral valve is one of the main valves of the heart. It sits between the left upper chamber and the left lower pumping chamber. Its job is to allow blood to move forward in one direction.
When the mitral valve does not close tightly, blood leaks backward. This condition is called mitral regurgitation.
There are two broad types:
1. Primary or Degenerative Mitral Regurgitation
This happens when the valve itself is damaged. Common causes include mitral valve prolapse, torn valve chords, age-related valve degeneration, or structural valve disease.
2. Secondary or Functional Mitral Regurgitation
Here, the valve may be structurally normal, but the heart chamber becomes enlarged or weak. Because of this, the valve leaflets cannot meet properly. This is commonly seen in patients with heart failure or poor pumping function.
Both types need careful evaluation because the treatment plan is different for every patient.
Symptoms of Mitral Regurgitation Patients Should Not Ignore
Many patients in India ignore valve disease symptoms because they assume they are due to ageing, asthma, obesity, weakness, or lack of fitness.
Common symptoms include:
- Breathlessness while walking or climbing stairs
- Breathlessness while lying flat
- Waking up at night due to breathing difficulty
- Fatigue or reduced stamina
- Palpitations or irregular heartbeat
- Swelling in the feet or ankles
- Repeated hospital admissions for heart failure
- Chest discomfort or heaviness
- Unexplained weakness in elderly patients
If these symptoms are present, an echocardiogram can help identify whether a leaking mitral valve is contributing to the problem.
Why Severe Mitral Regurgitation Should Not Be Delayed
A severely leaking mitral valve makes the heart work harder. Over time, this can lead to enlargement of the heart chambers, worsening heart failure, rhythm problems such as atrial fibrillation, pulmonary hypertension, and repeated fluid accumulation in the lungs.
The challenge is that patients often come late, after symptoms become severe. In valve disease, timing matters. The goal is to treat the right patient at the right stage before the heart becomes too weak or permanently damaged.
What Is MitraClip / TEER?
MitraClip is a device used in a minimally invasive procedure called TEER — Transcatheter Edge-to-Edge Repair.
In simple terms, the doctor reaches the mitral valve through a catheter, usually from a vein in the leg, and places a small clip on the leaking part of the valve. This helps the valve leaflets come closer together, reducing the backward leak.
The procedure is called “edge-to-edge repair” because the clip joins a portion of the valve edges together so that the valve closes better.
TEER is performed using advanced imaging guidance such as echocardiography and X-ray imaging. Standard procedural steps include vascular access, transseptal puncture, clip implantation, and closure of the access site.
Is MitraClip an Alternative to Open Heart Surgery?
MitraClip / TEER is not a replacement for surgery in every patient.
Open heart mitral valve repair remains the preferred option for many patients, especially younger patients, low-risk surgical patients, or those with valve anatomy better suited for surgery. However, TEER can be a valuable option for selected patients who are at high surgical risk or have severe symptoms despite medical treatment.
International heart valve guidelines support mitral TEER in selected patients with severe symptomatic mitral regurgitation, especially when surgical risk is high and valve anatomy is suitable.
This is why patient selection is extremely important.
Who May Be Suitable for MitraClip / TEER?
A patient may be considered for MitraClip / TEER if they have:
- Severe mitral regurgitation
- Breathlessness or heart failure symptoms
- High risk for open heart surgery
- Advanced age or frailty
- Poor heart pumping function
- Previous bypass surgery or previous heart surgery
- Kidney disease, lung disease, or other medical conditions increasing surgical risk
- Secondary mitral regurgitation due to heart failure, despite optimal medicines
- Valve anatomy suitable for clip placement
Suitability is confirmed only after detailed assessment by a structural heart specialist and heart team.
Who May Not Be Suitable for MitraClip?
MitraClip may not be suitable if:
- The mitral valve anatomy is not suitable
- The valve is too calcified or damaged
- The leak is located in an area where a clip cannot be placed effectively
- The valve opening may become too narrow after clipping
- There is active infection
- Surgery is clearly the better and safer long-term option
- The patient’s symptoms are not mainly due to mitral regurgitation
This is why a detailed echocardiography assessment is essential before deciding treatment.
Tests Needed Before MitraClip / TEER
Before planning TEER, patients usually require:
Echocardiogram
This is the first and most important test to confirm the presence and severity of mitral regurgitation.
Transesophageal Echocardiography — TEE
TEE gives a closer and clearer view of the mitral valve. It helps the doctor understand whether the valve is suitable for clip placement. Echocardiographic imaging is critical for assessing candidacy and guiding safe implantation during TEER.
ECG and Rhythm Evaluation
This helps identify rhythm problems such as atrial fibrillation.
Blood Tests
These assess kidney function, blood counts, clotting profile, and general fitness for the procedure.
Coronary Evaluation
Some patients may need coronary angiography or other tests to check for artery blockages.
Heart Team Discussion
The final decision is usually made after reviewing symptoms, valve anatomy, heart function, surgical risk, and patient goals.
How Is the MitraClip Procedure Done?
The procedure is usually performed in a cath lab or hybrid operating room.
Step 1: Anaesthesia and Monitoring
The patient is given anaesthesia or deep sedation depending on the case. Heart rhythm, blood pressure, oxygen levels, and imaging are closely monitored.
Step 2: Catheter Entry from the Leg
A catheter is inserted through a vein in the groin. There is no need to cut open the chest.
Step 3: Reaching the Mitral Valve
The catheter is guided to the heart. The doctor crosses from the right side of the heart to the left atrium through a controlled puncture in the atrial septum.
Step 4: Clip Placement
The MitraClip device is positioned over the leaking part of the mitral valve. The valve leaflets are grasped, and the clip is placed to reduce the leak.
Step 5: Leak Assessment
The doctor checks the valve immediately using echo imaging. If required, more than one clip may be placed.
Step 6: Catheter Removal
Once the result is satisfactory, the catheter is removed and the leg access site is closed.
Benefits of MitraClip / TEER
For suitable patients, MitraClip / TEER may offer important advantages:
- No open chest surgery
- No large surgical incision
- Usually no need for heart-lung machine
- Shorter recovery compared with open heart surgery
- Reduced mitral valve leakage
- Improvement in breathlessness and heart failure symptoms in selected patients
- Helpful option for elderly or high-risk patients
- Can reduce repeated heart failure admissions in selected cases
MitraClip is a minimally invasive treatment option for selected patients with primary or secondary mitral regurgitation.
Risks and Limitations of MitraClip
Like any heart procedure, MitraClip / TEER has risks. These may include:
- Bleeding from the leg access site
- Vascular complications
- Residual mitral regurgitation
- Need for more than one clip
- Mitral valve narrowing
- Infection
- Stroke, though uncommon
- Device-related complications
- Need for surgery in rare cases
- Recurrence of leakage over time
The goal is not just to perform the procedure, but to choose the right patient where the benefit is likely to be meaningful.
MitraClip vs Open Heart Surgery
| Factor | MitraClip / TEER | Open Heart Mitral Valve Surgery |
|---|---|---|
| Approach | Catheter through leg vein | Chest incision |
| Heart-lung machine | Usually not required | Usually required |
| Recovery | Faster in many patients | Longer recovery |
| Best suited for | Selected high-risk patients | Many low-risk or anatomically suitable patients |
| Valve result | Reduces leakage | Can repair or replace valve more completely in suitable cases |
| Patient selection | Very important | Also important |
Both treatments are valuable. The right choice depends on age, valve anatomy, heart function, symptoms, and surgical risk.
Why Patient Selection Is the Most Important Step
MitraClip is not just a device-based procedure. It is a decision-making process.
A successful result depends on:
- Correct diagnosis
- Correct grading of mitral regurgitation
- Understanding whether symptoms are truly due to valve leakage
- Checking valve anatomy in detail
- Evaluating heart function
- Assessing surgical risk
- Planning the procedure with advanced imaging
- Setting realistic expectations
In some patients, medicines may be enough. In others, surgery may be better. In selected high-risk patients, MitraClip / TEER may offer a powerful minimally invasive option.
Mitral Regurgitation and Heart Failure
Many patients with heart failure also have mitral regurgitation. When the heart becomes enlarged or weak, the mitral valve may leak more. This leakage further increases the burden on the heart, creating a cycle of worsening breathlessness, fluid retention, and hospital admissions.
For such patients, treatment usually begins with guideline-directed heart failure medicines. If severe leakage continues despite optimal treatment, TEER may be considered in selected patients after detailed evaluation.

Final Message for Patients
A leaky mitral valve is not always harmless. In many patients, it can silently worsen heart function and quality of life.
The good news is that treatment options have advanced. Selected patients with severe mitral regurgitation may now be treated with MitraClip / TEER, a minimally invasive valve repair procedure performed without open heart surgery.
However, the most important step is not the procedure itself — it is choosing the right treatment for the right patient at the right time.
If you or your family member has been diagnosed with severe mitral regurgitation, breathlessness, or heart failure symptoms, consult an experienced structural heart specialist to understand whether MitraClip / TEER is suitable.
