Mitral valve prolapse is one of the most common heart valve findings, affecting around two to three people in every hundred. The name sounds alarming, but for most people it causes no problems at all. Understanding when it matters, and when it does not, saves a great deal of unnecessary worry.
What is Mitral Valve Prolapse?
The mitral valve sits between the two chambers on the left side of the heart. It has two leaflets that close each time the heart contracts, stopping blood from flowing backwards. In mitral valve prolapse, one or both leaflets are slightly floppy and bulge back into the upper chamber as the valve closes.
Why Is It Usually Harmless?
In most people, the valve still closes well enough to keep blood moving in the right direction. There may be no leak, or only a trivial one, and the heart works normally. Many people are diagnosed by chance, when a doctor hears a click or murmur, or during an echocardiogram for something else.
When Does It Become Significant?
In a minority of people, the prolapse worsens over time, or one of the small cords supporting the valve stretches or breaks. The valve then leaks significantly, a condition called mitral regurgitation. Blood flows backwards with each beat, and the heart has to work harder to compensate. Over time, the heart can enlarge and weaken, and heart rhythm problems such as atrial fibrillation become more likely.
Symptoms To Watch For
Most people with mild prolapse have no symptoms. Some notice palpitations, which are usually harmless but worth mentioning. Symptoms that suggest a significant leak include breathlessness on exertion or when lying flat, tiredness, reduced exercise tolerance and swollen ankles. A sudden worsening of breathlessness can occur if a supporting cord breaks and needs urgent assessment.
How Is It Monitored?
An echocardiogram shows the structure of the valve, the size of any leak and how well the heart is coping. People with mild prolapse may need only occasional checks. Those with moderate or severe leaks are scanned more often, sometimes yearly.
When Is Treatment Needed?
Medicines can help control symptoms and problems such as high blood pressure or irregular heartbeats, but they cannot repair the damaged valve. Surgery may be needed if the leak is severe, causes symptoms or starts affecting the heart’s size or pumping function. Doctors may recommend surgery even if there are no symptoms. Treating the valve before permanent heart damage develops can improve long-term outcomes.
Repair Is Usually Preferred
For mitral valve prolapse, repairing the patient’s own valve is generally preferred over replacing it. Surgeons can reshape the leaflets, replace stretched or broken cords with artificial ones and tighten the ring around the valve. Repair preserves heart function well and usually avoids the need for lifelong blood thinners. In suitable patients, the operation can be performed through small incisions between the ribs rather than by opening the breastbone.
For patients at high surgical risk, catheter-based options to reduce the leak may be considered in specialised centres.
Prolapse and Heart Rhythm
Some people with mitral valve prolapse notice palpitations or skipped beats. Most of these are harmless extra beats, but a Holter monitor, which records the heart rhythm over 24 hours or longer, can confirm this. Rarely, prolapse is associated with more significant rhythm disturbances, which a cardiologist will assess.
Everyday Advice
Stay active, keep blood pressure controlled, limit caffeine if palpitations are bothersome and keep up good dental hygiene. Report new or worsening symptoms promptly rather than waiting for the next routine scan.
Choosing Where To Be Treated
Valve surgery outcomes depend heavily on the team. People researching the best multispeciality hospital in Dubai for valve care should ask whether mitral repair is routinely performed, and whether cardiology, cardiac surgery, imaging and rhythm specialists work together.
Where Is Mitral Valve Treatment Available in Dubai?
Aster Hospital Dubai, a group of five facilities in Mankhool, Al Qusais, Muhaisnah and Jebel Ali with more than 300 beds and over 35 specialities, provides heart valve disease treatment in Dubai including mitral valve repair, valve replacement with mechanical or biological valves and minimally invasive valve surgery. Patients are assessed with echocardiography, and rhythm specialists are available for associated problems such as atrial fibrillation.
For most people, mitral valve prolapse is a finding, not a disease. For the few who develop a significant leak, timely repair offers a good outlook.
