Mitral valve stenosis Y descent seen on the wedge tracings. If a trans-septal puncture is made during right heart catheterization, however, the pressure gradient can accurately quantify the severity of mitral stenosis. Chest X-ray may also assist in diagnosis, showing left atrial enlargement. Electrocardiography may show "P mitrale", that is, broad, notched P waves in several or many leads with a prominent late negative component to the P wave in lead V, and may also be seen in mitral regurgitation, and, potentially, any cause of overload of the left atrium. Thus, "P-sinistrocardiale" may be a more appropriate term. Treatment is not necessary in
Mitral valve replacement there will be a smaller scar in this location. Mitral valve replacement Mitral valve replacement is a cardiac surgical procedure in which a patient’s diseased mitral valve is replaced by either a mechanical or bioprosthetic valve. Mitral valve replacement is performed when the valve becomes too tight (mitral valve stenosis) for blood to flow into the left ventricle, or too loose (mitral valve regurgitation) in which case blood can leak back into the left atrium and thereby back into the lung. Mitral valve disease can occur from infection, calcification, inherited collagen disease, or other causes. Since a mitral valve replacement
