Video: Mitral valve regurgitation
The mitral valve is located between the upper left heart chamber (left atrium) and the lower left heart chamber (left ventricle). A healthy mitral valve keeps your blood moving in the right direction. A leaky valve doesn't close the way it should, allowing some blood to flow backward into the left atrium. If left untreated, a leaky valve could lead to heart failure.
