 * Associate Editor-In-Chief: Mohammed A. Sbeih, M.D. [mailto:msbeih@perfuse.org]

Overview
In patients with mitral regurgitation who have risk factors for Coronary artery disease, such as advanced age, hypercholesterolemia, and hypertension, or when there is a suspicion that mitral regurgitation is ischemic in origin, coronary angiography should be performed before surgery.

Class I
1. Left ventriculography and hemodynamic measurements are indicated when noninvasive tests are inconclusive regarding severity of MR, LV function, or the need for surgery. (Level of Evidence: C)

2. Hemodynamic measurements are indicated when pulmonary artery pressure is out of proportion to the severity of MR as assessed by noninvasive testing. (Level of Evidence: C)

3. Left ventriculography and hemodynamic measurements are indicated when there is a discrepancy between clinical and noninvasive findings regarding severity of MR. (Level of Evidence: C)

4. Coronary angiography is indicated before MV repair or MV replacement in patients at risk for CAD. (Level of Evidence: C)

Class III
1. Left ventriculography and hemodynamic measurements are not indicated in patients with MR in whom valve surgery is not contemplated. (Level of Evidence: C)}}
