Overview
Left and right heart catheterization as well as angiography may be useful in the assessment of the patient prior to aortic valve replacement surgery.
Cardiac Catheterization
Left heart catheterization is performed to simultaneously assess left ventricular and aortic pressures.
ACC/AHA Guidelines- Indications for Cardiac Catheterization (DO NOT EDIT) [1]

Class I1. Coronary angiography is recommended before AVR in patients with AS at risk for CAD. (Level of Evidence: B) 2. Cardiac catheterization for hemodynamic measurements is recommended for assessment of severity of AS in symptomatic patients when noninvasive tests are inconclusive or when there is a discrepancy between noninvasive tests and clinical findings regarding severity of AS. (Level of Evidence: C) 3. Coronary angiography is recommended before AVR in patients with AS for whom a pulmonary autograft (Ross procedure) is contemplated and if the origin of the coronary arteries was not identified by noninvasive technique. (Level of Evidence: C) Class III1. Cardiac catheterization for hemodynamic measurements is not recommended for the assessment of severity of AS before AVR when noninvasive tests are adequate and concordant with clinical findings. (Level of Evidence: C) 2. Cardiac catheterization for hemodynamic measurements is not recommended for the assessment of LV function and severity of AS in asymptomatic patients. (Level of Evidence: C) |
