The mitral valve is another one of the major heart valves. It regulates blood flow between the left atrium and left ventricle. Certain conditions can cause this valve to leak so that when the heart pumps blood goes backward from the left ventricle into the left atrium. This is known as mitral regurgitation. This often causes symptoms of shortness of breath and heart failure. Until recently the only option for repair of this abnormality has been open-heart surgery in which the surgeon repairs were replaces the valve. A new technique has been developed for patients who have this condition and are not good candidates for open-heart surgery involved using a catheter that is inserted through a small incision in the leg to place a small clip which functions as a staple to attach the edges of the leaking valve together. This can decrease the amount of mitral regurgitation and improve the symptoms of shortness of breath. The physicians of the Hartford Cardiac Laboratory were the first to use this device in Connecticut.
