If the coronary ostium faced the sealed parts of the THV or the tilted-up native leaflet (NL), this was defined as THV- or NL-related challenging coronary access, respectively. If coaxial engagement was not allowed due to interference from the unwrapped frame, THV-related complex coronary access was defined.<h4>Results</h4>The incEuroIntervention : journal of EuroPCR in collaboration with the Working Group on Interventional Cardiology of the European Society of Cardiology203-212https://www.ebi.ac.uk/biostudies/studies/S-EPMC9912966biostudies-literatureCoronary access after transcatheter aortic valve replacement in bicuspid versus tricuspid aortic stenosis.PMC9912966Peng YZhu ZChen MFeng YChen FWei XLi QXiong TZhao ZJia KLi XLi YHe SOu YWang XWei JfalseCoronary access after transcatheter aortic valve replacement in bicuspid versus tricuspid aortic stenosis.<h4>Background</h4>It is unknown whether there are differences in coronary access after transcatheter aortic valve replacement (TAVR) between bicuspid and tricuspid anatomy.<h4>Aims</h4>Our aim was to investigate coronary access after TAVR using a self-expanding transcatheter heart valve (THV) in bicuspid versus tricuspid aortic valves (BAV vs TAV), based on CT simulation.<h4>Methods</h4>A total of 86 type 0 BAV, 70 type 1 BAV, and 132 TAV patients were included.
