Interaction Between Self-Expanding Transcatheter Heart Valves and Coronary Ostia: An Angiographically Based Analysis of the Evolut R/Pro Valve System.

CONCLUSIONS: The Evolut R/Pro neo-valve was positioned below the LCA ostium in the vast majority of cases (85%), but an implantation depth ≤6mm was associated with a higher rate of neo-valve positioning at or above the coronary ostia level. Considering the current tendency of very high (aortic) valve implants to avoid conduction disturbances, future studies should determine the impact of high Evolut R/Pro positioning on coronary access issues post TAVR.
