Cardiac computed tomographic angiography (CTA) using multidetector computed tomographic scanners has proven to be a reliable technique to image the coronary vessels. CTA also provides excellent visualization of the mitral and aortic valves, and yields useful information regarding valve anatomy and function. Accordingly, an assessment of the valves should be performed whenever possible during CTA interpretation. In this paper, we highlight the imaging features of common functional and structural left-sided valvular disorders that can be seen on CTA examinations.
