Short Editorial Alsidawi Aortic regurgitation assessment by echo Arq Bras Cardiol. 2020; 115(2):261-262 Furthermore, utilizing other modalities to assess AR severity might be needed when echocardiographic and clinical data are inconclusive or contradictory. Cardiac Magnetic Resonance Imaging (MRI) has an important and promising role in assessing AR severity, especially with eccentric jets or peri-prosthetic valvular leaks. It helps assess the regurgitant fraction utilizing phase-contrast imaging and left and right ventricular size and function with good accuracy. 7 Cardiac Computed Tomography (CT) can also be helpful to identify peri-prosthetic leaks and guide surgical and percutaneous procedures. 8 Finally, a well-performed aortogram carried out in the catheterization laboratory can be very valuable, when other testing modalities are inconclusive. 1.
