Overview
In patients with MR who have risk factors for CAD (e.g., advanced age, hypercholesterolemia, or hypertension) or when there is a suspicion that MR is ischemic in origin (either because of known myocardial infarction or suspected ischemia), coronary angiography should be performed before surgery.
3.6.3.8. Indications for Cardiac Catheterization 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)
