In rare cases, a tumor (myxoma) growing on the valve surface or in the left atrium of the heart can cause a blockage of the mitral valve that is similar to mitral valve stenosis. Myxomas are tumors of connective tissue. They can occur almost anywhere in the body and can become quite large. When they occur, they can either block the valve opening or restrict the movement of the valve and prevent it from opening completely.
