Mitral regurgitation is a valvular disease characterized by a heart where the systemic cardiac output is determined by the relative resistances presented by pulmonary and systemic circulations during ventricular systole. Because of regurgitation through the mitral valve, the left atrial and pulmonary vascular pressures are increased above normal. This causes pulmonary congestion or oedema in more severe degrees of mitral regurgitation.
