  • Prospective cohort study
  • single-centre
  • investigator-driven
  • consecutive patients

Authors' conclusion

Unsuccessful coronary cannulation after TAVR using self-expanding THVs implanted using CA techniques was reported in 5.5% of cases, with the majority involving the Evolut THV. Commissural misalignment affected coronary cannulation after TAVR mostly in Evolut recipients.

Exposure
