An 81-year-old male following TAVR with a 31-mm Medtronic CoreValve*. Coronal oblique MPR of an enhanced MDCT before TAVR (a) and coronal oblique thick MPR of a non-enhanced MDCT following TAVR (b). Key anatomic landmarks: Native aortic valve annulus plane (solid black arrow), left main coronary artery emanating from the left coronary sinus of Valsalva (dotted black arrow), sinotubular junction (dotted white arrow), ascending aorta approximately 4 cm above the native aortic valve annulus plane (solid white arrow); Medtronic CoreValve (double-headed arrows) and mitral valve annular calcifications (*). Note normal positioning of the Medtronic CoreValve with the upper portion at ascending aorta (double-headed white solid arrow), mid portion at the sinuses of Valsalva (double-headed dotted white arrow) and lower portion, “inflow” aspect at or just below the native aortic valve annulus plane (double-headed solid black arrow)
