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 insufficiency during a cardiac cycle. Methods that have been used to assess the regurgitant fraction in mitral regurgitation include echocardiography, cardiac catheterization, fast CT scan, and cardiac MRI. The echocardiographic technique to measure the regurgitant fraction is to determine the forward flow through the mitral valve (from the left atrium to the left ventricle) during ventricular diastole, and comparing it with the flow out of the left ventricle through the aortic valve in ventricular systole. This method assumes that the aortic valve does not suffer from aortic insufficiency. Another way to quantify the degree of MR is to determine the area
