Topic: Mitral Valve Prolapse
Question: What are the treatments for Mitral Valve Prolapse ?
Answer: Most people who have mitral valve prolapse (MVP) dont need treatment because they dont have symptoms and complications.
                
Even people who do have symptoms may not need treatment. The presence of symptoms doesnt always mean that the backflow of blood through the valve is significant.
                
People who have MVP and troublesome mitral valve backflow may be treated with medicines, surgery, or both.
                
The goals of treating MVP include:
                
Correcting the underlying mitral valve problem, if necessary
                
Preventinginfective endocarditis,arrhythmias, and other complications
                
Relieving symptoms
                
Medicines
                
Medicines called beta blockers may be used to treatpalpitationsand chest discomfort in people who have little or no mitral valve backflow.
                
If you have significant backflow and symptoms, your doctor may prescribe:
                
Blood-thinning medicines to reduce the risk of blood clots forming if you haveatrial fibrillation.
                
Digoxin to strengthen your heartbeat.
                
Diuretics (fluidpills) to remove excess sodium and fluid in your body and lungs.
                
Medicines such as flecainide and procainamide to regulate your heart rhythms.
                
Vasodilators to widen your blood vessels and reduce your hearts workload. Examples of vasodilators are isosorbide dinitrate and hydralazine.
                
Take all medicines regularly, as your doctor prescribes. Dont change the amount of your medicine or skip a dose unless your doctor tells you to.
                
Surgery
                
Surgery is done only if the mitral valve is very abnormal and blood is flowing back into the atrium. The main goal of surgery is to improve symptoms and reduce the risk ofheart failure.
                
The timing of the surgery is important. If its done too early and your leaking valve is working fairly well, you may be put at needless risk from surgery. If its done too late, you may have heart damage that can't be fixed.
                
Surgical Approaches
                
Traditionally, heart surgeons repair or replace a mitral valve by making an incision (cut) in the breastbone and exposing the heart.
                
A small but growing number of surgeons are using another approach that involves one or more small cuts through the side of the chest wall. This results in less cutting, reduced blood loss, and a shorter hospital stay. However, not all hospitals offer this method.
                
Valve Repair and Valve Replacement
                
In mitral valve surgery, the valve is repaired or replaced. Valve repair is preferred when possible. Repair is less likely than replacement to weaken the heart. Repair also lowers the risk of infection and decreases the need for lifelong use of blood-thinning medicines.
                
If repair isnt an option, the valve can be replaced. Mechanical and biological valves are used as replacement valves.
                
Mechanical valves are man-made and can last a lifetime. People who have mechanical valves must take blood-thinning medicines for the rest of their lives.
                
Biological valves are taken from cows or pigs or made from human tissue. Many people who have biological valves dont need to take blood-thinning medicines for the rest of their lives. The major drawback of biological valves is that they weaken over time and often last only about 10 years.
                
After surgery, youll likely stay in the hospitals intensive care unit for 2 to 3 days. Overall, most people who have mitral valve surgery spend about 1 to 2 weeks in the hospital. Complete recovery takes a few weeks to several months, depending on your health before surgery.
                
If youve had valve repair or replacement, you may need antibiotics before dental work and surgery. These procedures can allow bacteria to enter your bloodstream. Antibiotics can help prevent infective endocarditis, a serious heart valve infection. Discuss with your doctor whether you need to take antibiotics before such procedures.
                
Transcatheter Valve Therapy
                
Interventional cardiologists may be able to repair leaky mitral valves by implanting a device using a catheter (tube) inserted through a large blood vessel. This approach is less invasive and can prevent a person from havingopen-heart surgery. At present, the device is only approved for people with severe mitral regurgitation who cannot undergo surgery.
