Coronary ostial eccentricity in severe aortic stenosis: Guidance for BASILICA transcatheter leaflet laceration

Eccentricity of coronary ostial positions in relation to the aortic valve cusp may influence the target laceration location in BASILICA. This report highlights the distribution of eccentric coronary ostia which showed that RCA ostia often have an eccentric origin towards the non-coronary cusp, especially in native aortic valves, while LCA ostia commonly originate in the center of the cusp. This finding may contribute to better performance of BASILICA procedures.
