In mitral regurgitation, the mitral valve does not close properly, and, therefore, leaks. Compare the differences in the circumference of the mitral valve and the size of its opening in mitral regurgitation with that in a normal heart. As a result of the leak backward from the left ventricle, the left atrium, pulmonary artery and right ventricle are enlarged. The left ventricle also is enlarged (it receives the leaked volume as well as the normal forward flow), but the left ventricular free wall and inter-ventricular septum remain normal in thickness.
