Mitral valve replacement gradually to regain strength. Patients who have physically demanding jobs will have to wait a little longer than those who don’t. Patients are also restricted from driving a car for six weeks after the surgery. Once a person has a mitral valve procedure, they are required to have prophylactic antibiotics as a preventative measure against infection whenever they have dental work done. Some scarring occurs after surgery. For median sternotomy (access through the sternum, or breastbone), the patient will have a vertical scar on the anterior chest above the sternum. If the heart is accessed from under the left breast
Mitral valve about 20% to the volume in the left ventricle prior to ventricular systole, and is known as the "atrial kick". The mitral annulus changes in shape and size during the cardiac cycle. It is smaller at the end of atrial systole due to the contraction of the left atrium around it, like a sphincter. This reduction in annulus size at the end of atrial systole may be important for the proper coapting of the leaflets of the mitral valve when the left ventricle contracts and pumps blood. Leaking valves can be corrected by mitral valve annuloplasty, a common surgical procedure
