  1. Mitral Valve Repair Surgery (Commissurotomy) for Mitral Valve Stenosis

    Commissurotomy is an open-heart surgery that repairs a mitral valve that is narrowed from mitral valve stenosis. It is also called open commissurotomy.During this surgery, a person is put on a heart-lung bypass machine. The surgeon removes calcium deposits and other scar tissue from the valve leaflets. The surgeon may cut parts of the valve structure. This surgery opens the valve. It is used for people who have severe narrowing of the valve and aren't good candidates for balloon valvotomy.

  2. Heart Problems: Living With an ICD

    An implantable cardioverter-defibrillator (ICD) helps protect you against dangerous heart rhythms. It's important to know how this device works and how to keep it working right. Learning a few important facts about ICDs can help you get the best results from your device.You may have a device that combines an ICD with a pacemaker, which keeps your heart from beating too slowly. For more information on pacemakers, see Heart Problems: Living With a Pacemaker.Key pointsAvoid strong magnetic and electrical fields. These can keep your device from working right. Most office equipment and home appliances are safe to use. Learn which things you should use with caution and which you should stay away from.Know what to do when you get a shock from your ICD. Be sure that any doctor, dentist, or other health professional you see knows that you have an ICD. Always carry a card in your wallet that tells what kind of device you have. Wear medical alert jewelry that says you have an ICD. Have your

  3. Congenital Heart Defects - What Happens

    Congenital heart defects happen when the heart does not form normally as the unborn baby (fetus) grows in the womb. Heart defects may cause problems with blood flow through the heart after a baby is born.

  4. Ventricular Tachycardia - Topic Overview

    If you have supraventricular tachycardia (SVT), go to the topic Supraventricular Tachycardia.What is ventricular tachycardia?Ventricular tachycardia is a fast heart rhythm that starts in the lower part of the heart (ventricles). If left untreated, some forms of ventricular tachycardia may worsen and lead to ventricular fibrillation, which can be life - threatening. What causes ventricular ...

  5. Mitral Valve Disease: Heart Rhythm Problems - Topic Overview

    A complication of mitral valve stenosis or mitral valve regurgitation (MR) is an irregular heartbeat (arrhythmia).This irregular heartbeat is created by a disruption in a web of nerves covering the surface of the heart. These nerves send electrical signals that cause your heart to contract and pump blood out of the heart. This web of nerves is controlled by a collection of cells on the right atrium called the sinoatrial node. As it fires, so do the rest of the nerves, causing all of the muscle cells in your heart to contract, producing one forceful pump.As mitral valve stenosis or MR stretches out your heart, it too can disrupt this web of nerves. Communication pathways may weaken because the sinoatrial node is no longer working correctly. Without clear signals from this node, the nerves begin to fire randomly, creating a chaotic network of electrical signals. When this happens, the heart is no longer able to pump with one motion, and instead it starts beating irregularly

  6. Mitral Valve Prolapse - Medications

    People with mitral valve prolapse (MVP) usually do not need medications, especially if they do not have mitral valve regurgitation. Medications cannot correct bulging (prolapse) of the mitral valve or prevent many of the complications that can develop. However, medication is sometimes used to control symptoms or prevent infection.Medication choicesMedications may help relieve certain symptoms ...

  7. Cardiac Arrest - Topic Overview

    In cardiac arrest, the heart suddenly stops beating. This causes blood to stop pumping to the body. If the heartbeat is not restarted within minutes, the person will die. This problem is also called sudden cardiac arrest.Cardiac arrest is different from a heart attack, which happens when part of the heart muscle dies because blood flow to it has been blocked.What causes it?Cardiac arrest is usually caused by a problem with the heart's electrical system. In most cases, the heart's rhythm is too fast and irregular. This problem is called ventricular fibrillation (say ven-TRICK-yuh-ler fib-ruh-LAY-shun). The lower chambers of the heart (ventricles) quiver very fast and can't pump blood.But cardiac arrest often happens to people who didn't know they had a heart problem. Some other health problems can increase the chance of a deadly heart rhythm. They include:Heart disease (coronary artery disease).A heart attack.Heart failure.Hypertrophic cardiomyopathy (say hy-per-TROH-fik
