Medium or severe mitral regurgitation became more common as echocardiographic grade increased. MR grades 3 and 4 were collectively defined as apparent mitral regurgitation. Mitral regurgitation was graded using the ratio of regurgitant jet area to left atrial area. Early structural dilation can produce mitral regurgitation through papillary muscle displacement and annular dilation.
