MitraClip

Your mitral valve sits between the two left chambers of your heart, opening to let blood flow forward and closing to prevent it from leaking backward. When this valve becomes leaky—a condition called mitral regurgitation—blood flows backward with each heartbeat instead of moving forward to your body. This makes your heart work harder and causes shortness of breath, fatigue, and eventually heart failure. Traditional treatment required open-heart surgery to repair or replace the valve. But MitraClip offers a less invasive option.

Overview

MitraClip is a way to fix a leaky heart valve without major surgery. Instead of opening your chest, a doctor threads a thin tube through a vein in your groin up to your heart and delivers a small clip that reduces the leak.

Your mitral valve opens and closes with each heartbeat. When it leaks, blood flows backward instead of forward. Your heart must pump extra blood to make up for this, which exhausts it over time.

The clip holds the valve leaflets together in the middle, like pinning a curtain that won’t close properly. This doesn’t make the valve perfect, but it reduces severe leaking to mild leaking. Most people feel much better within weeks—they breathe easier and have more energy.

You’re asleep during the 2-3 hour procedure. You typically go home after 2-4 days and return to normal activities within 2-3 weeks, much faster than the months needed after open-heart surgery.

Who Needs This

Not everyone with a leaky valve needs MitraClip. You’re a candidate if specific conditions apply.

• You must have severe leaking causing symptoms like shortness of breath, extreme fatigue, or swelling. If your leak is severe but you feel fine, the procedure isn’t right—your valve might need fixing eventually, but not yet.
• You must be too risky for traditional surgery or the surgical team decides MitraClip is better for you. High risk means being elderly, having multiple health problems, previous chest surgeries, severe lung disease, or being too frail for major surgery.
• Your valve anatomy must be suitable. Not all leaky valves can be fixed with a clip. The procedure works best when the leak comes from the central part of the valve. Heavily damaged or calcified valves might not work with MitraClip.
• A team of heart doctors and surgeons reviews your case together. You get detailed ultrasound images of your valve. The team looks at these images, your symptoms, surgical risk, and overall health to decide if MitraClip is right for you.
• Two groups benefit most: elderly patients with damaged valves who can’t handle surgery, and heart failure patients whose enlarged hearts have stretched the valve open, causing leaks.

Preparing for the Procedure

Getting ready involves several steps to ensure everything goes safely.

• You’ll have thorough heart ultrasounds to map your valve from every angle. This shows whether the clip can work and helps plan the procedure. Sometimes you need heart catheterization beforehand to check your coronary arteries.
• Blood tests check your kidney function and blood counts. Your doctor reviews all medications—you’ll get specific instructions about what to take or stop. Usually, blood thinners continue since you need some for the procedure.
• Don’t eat or drink anything after midnight before your procedure. You’ll be under general anesthesia, so an empty stomach is important.
• Arrange for someone to drive you home and stay with you for at least 24 hours after.
• Plan to stay in the hospital 2-4 days. You need monitoring to make sure the clip works well.
• If you need dental work, get it done beforehand. After you have the clip, you’ll need antibiotics before any dental procedures.
• The night before, shower with antibacterial soap if provided. Don’t use lotions or deodorants the morning of the procedure.

What Happens During the Procedure

You’ll be completely asleep, so you won’t feel or remember anything. Here’s what happens while you’re under anesthesia.

• You’re in a special operating room with advanced imaging equipment. The anesthesiologist puts you to sleep and places a breathing tube.
• A thin probe with an ultrasound goes down your throat. This stays there the whole time, providing live images of your valve that guide every step.
• The doctor makes a small puncture in the vein in your groin and threads a large catheter up through your blood vessels to your heart. The catheter goes from the right side of your heart to the left side by puncturing through the wall separating them.
• Once in the left upper chamber, the catheter carrying the MitraClip moves above your mitral valve. The clip opens—it has two arms with grippers that spread apart.
• Using ultrasound guidance, the doctor positions the clip so it straddles both valve leaflets. The clip advances through the valve, grabs both leaflets, and pulls them together.
• The doctor checks with ultrasound to confirm the leaflets are properly grasped and the leak is smaller. If it looks good, the clip releases from the catheter and stays permanently on your valve. If one clip isn’t enough, a second or even third clip can be placed.
• The whole procedure takes 2-3 hours. Then all tubes are removed and you’re taken to recovery.

After the Procedure

• You wake up gradually in the intensive care unit. Your throat might be sore from the breathing tube and ultrasound probe, but this passes quickly.
• You’ll have some discomfort at the groin puncture site, but it’s manageable with pain medication. You must lie relatively flat for several hours to prevent bleeding.
• The next day, you get another heart ultrasound to confirm the clip is working. Some leaking usually remains—the goal is reducing severe leaking to moderate or mild, not eliminating it completely.
• Most people stay 2-4 days in the hospital. Physical therapy helps you start walking safely the day after the procedure.
• You’ll take blood thinners for 3-6 months while tissue grows over the clip. After that, just aspirin is usually enough. Your doctor gives you specific instructions about all medications.

Recovery at Home

Recovery is much faster than open-heart surgery, but you still need to take it easy initially.

• The first week, do light activity only. Walk around your house and gradually increase distance. Avoid heavy lifting or strenuous exercise. Expect to feel tired—this improves over the first few weeks.
• Keep the groin puncture site clean and dry. Watch for excessive swelling, persistent bleeding, redness, or warmth that might signal infection.
• Take all medications exactly as prescribed. Blood thinners are crucial while tissue grows over the clip.
• Most people notice big improvements within 2-4 weeks. Breathing becomes easier, energy returns, and activities that were too hard become manageable again.
• You can usually drive after about a week and return to work within 2-3 weeks—much faster than the 6-8 weeks needed after traditional surgery.
• Follow-up appointments happen regularly. You’ll have heart ultrasounds at 1 month, 6 months, and then yearly to monitor how the clip is working.

What to Expect

Understanding realistic outcomes helps you know if the procedure succeeded.

• About 85-90% of people have significantly reduced leaking right after the procedure. Severe leaking becomes moderate or mild in most cases.
• The real measure is how you feel. About 80-85% of people report feeling much better within weeks to months. Shortness of breath decreases, energy improves, and quality of life gets much better. Things that were impossible become doable again.
• This improvement usually lasts. Studies following people for 3-5 years show most keep feeling better, though some develop recurrent leaking as clips loosen or the valve continues changing.
• MitraClip doesn’t work for everyone. About 10-15% don’t get enough leak reduction. These patients might need additional clips, traditional surgery, or continued medication management.
• Heart function often improves after MitraClip, especially in people whose hearts were weakened from working against a severe leak for years. Once the heart no longer pumps extra blood backward, it can recover.

Possible Problems

MitraClip is safer than open-heart surgery, but risks exist.

• Bleeding at the groin puncture site is most common, usually minor but occasionally needing treatment.
• The valve can be damaged during the procedure. Leaflets can tear or the clip can detach. This rarely requires emergency surgery to fix or replace the valve.
• Stroke happens in about 1-2% of procedures if blood clots or air bubbles travel to the brain during the procedure.
• The clip might not reduce leaking enough to help. This occurs in about 10-15% of cases.
• Sometimes the clip comes loose and travels through blood vessels. It must be retrieved with catheters or surgery.
• By clipping leaflets together, you make the valve opening smaller. If clips are too aggressive, the opening might become too narrow and block forward blood flow.
• About 2-3% of people die within 30 days of the procedure, though risk depends on how sick you were before. This is still much lower than traditional surgery risk.

Key Points

• MitraClip repairs a leaky mitral valve without open-heart surgery. A catheter threaded through your groin vein delivers a clip to your heart that holds valve leaflets together, reducing backward blood flow.
• You’re a candidate if you have severe mitral regurgitation causing symptoms and are too high-risk for traditional surgery or your heart team determines MitraClip is your best option.
• The procedure takes 2-3 hours under general anesthesia. A catheter goes through your groin vein to your heart, where a small clip is placed on the valve to reduce leaking.
• Recovery is much faster than surgery. Most people go home after 2-4 days and return to normal activities within 2-3 weeks instead of months.
• About 85-90% of people have significantly reduced leaking after the procedure. Most feel dramatically better within weeks—easier breathing, more energy, and better quality of life.
• You need blood thinners for 3-6 months while tissue grows over the clip. After that, just aspirin is usually enough.
• Complications are uncommon but can include bleeding, stroke, valve damage requiring emergency surgery, or inadequate leak reduction.
• The improvement usually lasts for years, though some people develop recurrent leaking over time and might need additional treatment.
• Work closely with your cardiologist to determine if MitraClip is right for you. For appropriate patients, it offers symptom relief and improved quality of life with much faster recovery than traditional surgery.
