Coronary angiography showing a tapering distal LMS lesion, with critical proximal LAD disease. There is also a severe ostial D1 lesion, severe proximal intermediate disease, and diffuse diabetic disease throughout.

CA (Figure 1, Supplementary Video 2) confirmed a tapering distal left main lesion, with critical proximal LAD disease and further severe ostial D1 lesion and diffuse diabetic disease throughout, and severe proximal intermediate disease. TTE). The LAD was predilated using a 2.5-mm balloon with subsequent stent deployment with a 3.5 x 21 mm Ultimaster  sirolimus-eluting stent (Terumo Interventional Systems) to the distal left main/LAD (Supplementary Figure 1, Supplementary Video 3).
(A) The densely packed, horizontally aligned, narrow cells seen in Lotus valves can result in difficulty with intubating the coronary ostia; (B,C) the large cells and low density mesh of Sapien valves enable coronary cannulation; (D) the large cell area of Portico and its annular positioning facilitates easy coronary engagement although tall frame height can be challenging; (E) the shorter stent design and larger cells of the upper section of the Allegra stent frame might allow for easier coronary access; (F) Acurate Neo valves display both favorable (short stent component) and unfavorable (tall commissural post) features; (G) the relatively tall frame of Evolut R can prove a challenge in coronary angiography, although the presence of a black marker in principle facilitates optimal placement to simplify future coronary access.
