Zusammenfassung:	The aim of this study was to evaluate the risk of coronary obstruction due to sinus sequestration in redo transcatheter aortic valve replacement (TAVR) using post-TAVR computed tomography (CT). Little information is available regarding the risk of coronary obstruction due to sinus sequestration in redo TAVR inside a previously implanted TAV. Post-TAVR CT of 66 patients who received an Evolut R or Evolut PRO and 345 patients who received a SAPIEN 3 were analyzed. Redo TAVR was considered at risk of coronary obstruction due to sinus sequestration if: 1) the prior TAV commissure level was above sinotubular junction (STJ); and 2) the distance between TAV and STJ was
