case_images: Pre-procedural computed tomography angiography (CTA) revealed a mean aortic annulus diameter of 26.4 mm, an annulus area of 548 mm2 and perimeter of 85.2 mm, with a moderately calcified tricuspid aortic valve:Figure 1. Careful analysis of CTA reconstructions indicated adequate coronary ostia height and acceptable sinuses of Valsalva (SOV) and sinotubular junction (STJ) dimensions (Figure 1D-1DF).

case_images: On third attempt, position check immediately before release, showed what seemed to be a good position, however careful prosthesis-cuspid alignment was not guaranteed (Figure 2).
