What it is

Think of the mitral valve as a pair of swing doors between the heart's left collecting chamber and its main pump. Every beat, the doors open to let blood through, then swing shut in perfect alignment so nothing flows backwards. In mitral regurgitation the two door edges no longer meet — because the doors have stretched or a supporting cord has given way, or because a weakened, enlarged heart has pulled the frame apart. With every beat, part of the blood surges backwards into the collecting chamber and the lungs behind it — which is why the breathlessness, and why the heart works harder for less.

TEER — Transcatheter Edge-to-Edge Repair, best known by the name of its most widely used device, MitraClip — repairs the doors without opening the chest. A slim catheter travels up a leg vein to the heart. Guided continuously by 3D echo from a probe in the food pipe (TEE), a small clip grasps both door edges exactly where they fail to meet and pins them together. The one large leaking opening becomes two smaller, sealing ones — the leak falls at once, on the table, while the heart keeps beating.

The clip stays permanently and your own tissue grows over it within months. For patients too high-risk for open surgery — and for heart-failure patients whose leak persists despite the best medicines — this is often the difference between repeated hospital admissions and a life that opens back up.

The severity of the leak — and whether TEER can help — is graded on an echo, and if you're holding that report, Heart Simplified explains what each line actually means ↗.

Who it's for

Severe mitral regurgitation with breathlessness or fatigue
High or prohibitive surgical risk
Heart failure patients whose leak persists despite optimal medication
Selected patients with degenerative (structural) valve leaks

Signs you might need it

Breathlessness on exertion — and, as the leak worsens, when lying flat or waking you at night
Tiredness and a shrinking capacity for daily activity
Palpitations — the stretched upper chamber often slips into atrial fibrillation
Swollen ankles or legs as fluid backs up
Repeated hospital admissions for heart failure despite taking medicines properly
A murmur your doctor hears — sometimes the first clue, before any symptom

How we confirm you need it

Echocardiography (echo) — confirms the leak and grades how severe it is
Transoesophageal echo (TEE) — the decisive test: it shows the exact mechanism of the leak and whether the leaflets suit a clip
ECG and blood tests, including heart-failure markers (BNP/NT-proBNP)
Coronary angiography in selected patients, to complete the picture before any intervention
Heart Team review — interventional cardiologist, cardiac surgeon and heart-failure physician agree whether surgery, the clip, or medicines alone serves you best

How it happens, step by step

Imaging workup

A transoesophageal echo (TEE) maps the leak's exact mechanism and confirms the anatomy suits clip repair.

Venous access

Under general anaesthesia, the device travels up a leg vein to the heart, crossing to the left side through a small, controlled septal puncture.

Leaflet grasp

Guided continuously by 3D echo, the clip grasps both leaflets exactly at the leak and closes them — creating a double-orifice valve that seals the regurgitation.

Assessment & release

The leak is re-measured on the table; additional clips are placed if needed before the system is withdrawn.

The benefits

No chest incision, no heart-lung machine — access is through a leg vein under general anaesthesia
The leak is reduced immediately — the result is visible on the table before the device is ever released
Breathlessness eases and, in landmark trials of carefully selected heart-failure patients, clip repair on top of good medicines reduced hospital admissions and improved survival compared with medicines alone
A genuine option for patients declined for open surgery
Short hospital stay — typically two to three days — and a quick return to daily life

The risks

Access-site problems at the leg vein — bruising or bleeding, uncommonly needing treatment
A small risk of stroke, as with any procedure inside the left heart
Partial detachment of the clip from one leaflet, which can need a second clip or, rarely, surgery
A residual or recurrent leak in a minority of patients — follow-up echoes exist to catch this early
Making the valve too tight (mitral stenosis) — the reason the result is measured meticulously before the clip is released
Rarely, bleeding around the heart (pericardial effusion) from the septal crossing — monitored for closely during and after the procedure

Alternatives we'll discuss

Mitral valve surgery

Open-heart repair — and replacement where repair isn't possible — remains the benchmark for fit patients with degenerative leaks, offering the most complete and durable correction. The trade-off is the chest opening, the heart-lung machine, and a longer recovery. When surgery serves you better, the Heart Team says so plainly.

Heart failure medicines & device therapy

For leaks driven by a weakened, enlarged heart (functional MR), guideline medicines — and CRT where indicated — are always the first step; they can shrink the heart and reduce the leak. The clip is considered when a significant leak persists despite them, not instead of them.

Watchful monitoring

Moderate leaks without symptoms are often watched with scheduled echoes rather than treated. Watching is an active decision: the moment symptoms appear or the heart starts changing, the balance shifts towards repair.

Preparing for it

Complete the imaging — echo and the all-important TEE that maps your valve's anatomy
Blood tests, and a review of blood thinners with the team
An anaesthesia review — the procedure is done under general anaesthesia
Fast from midnight before the procedure as instructed
Plan for two to three nights in hospital and someone to accompany you home

Recovery

Usually 2–3 days in hospital
No sternal wound — activity resumes quickly
Breathlessness often improves within days to weeks
Continued heart failure medications and echo follow-up

Results & durability

The leak is reduced to mild or less in the great majority of suitably selected patients
Breathlessness and effort tolerance typically improve over days to weeks
In trial populations of heart-failure patients, fewer hospital admissions and better survival than medicines alone
The clip is permanent — covered by the heart's own tissue within months
Follow-up echoes at scheduled intervals keep the repair — and the rest of the valve — under watch

Cost & insurance

What affects the cost

The clip device is the largest single component — and some patients need two clips, which the team discusses beforehand as a possibility, not a surprise
General anaesthesia, the TEE guidance, hospital and room category make up the rest
TEER is covered by several private insurance policies; coverage varies widely by plan — we help you check yours before anything is scheduled
For a figure specific to your valve and cover, please book a consultation — generic prices online rarely match reality

Common questions

Is MitraClip the same as TEER?+

Essentially, yes. TEER (Transcatheter Edge-to-Edge Repair) is the medical name of the procedure; MitraClip is the most widely used clip system for doing it — so most patients know the whole procedure by that name. If your doctor has said 'MitraClip', this is the procedure they mean.

Is the MitraClip procedure painful?+

No. It is done under general anaesthesia, so you sleep through it. There is no chest incision — afterwards you have only a small puncture site at the top of the leg, and most patients are surprised how little it troubles them.

How long does the clip last? Will it need replacing?+

The clip is a permanent implant — it does not need replacing. Within months your own heart tissue grows over it, making it part of the valve. Follow-up echoes keep the repair under watch.

What if one clip isn't enough?+

Additional clips can be placed in the same sitting — the device is only released once the leak reduction is satisfactory on the table. Needing two clips is common and is not a complication.

TEER or open-heart surgery — which is better for me?+

It depends on why the valve leaks, your surgical risk, and your overall condition. For fit patients with a degenerative leak, surgical repair remains the benchmark. For patients at high surgical risk, or with heart-failure-related leaks despite good medicines, the clip offers meaningful benefit at far lower procedural risk. Every case goes through the Heart Team.

Am I too old or too weak for this procedure?+

TEER was designed precisely for patients considered too frail for open surgery — age by itself rarely rules it out. What matters is your valve's anatomy on the TEE and your overall condition, both of which the workup assesses honestly.

Will the clip cure my heart failure?+

It treats the leak, which is one important driver of heart failure — it is not a replacement for your heart failure medicines. In the right patients the combination reduces breathlessness and hospital admissions; your medicines almost always continue alongside.

How soon will I feel better, and when can I go home?+

Most patients go home in two to three days. Because the leak is reduced immediately, breathlessness often starts easing within days to weeks as the heart and lungs adjust.

Can the leak come back after the clip?+

In most patients the reduction holds. In a minority, a residual or recurrent leak needs a second procedure — sometimes another clip, occasionally surgery. This is exactly why follow-up echoes are scheduled rather than assumed unnecessary.

If the clip doesn't work, can surgery still be done?+

Usually yes — a clip does not automatically close the surgical door, though it can make later repair more complex. This trade-off is discussed openly in the Heart Team review before we ever recommend the clip.
