Coronary Cannulation Following Transcatheter Aortic Valve Replacement (TAVR) Using Self-Expanding Devices With Commissural Alignment: The RE-ACCESS 2 Study
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.
Study context
- Population
- Consecutive TAVR patients receiving self-expanding transcatheter heart valves (THVs) implanted using commissural alignment, single centre, September 2021–December 2022
- Participants
- 127 patients
- Exposure
- Evolut vs ACURATE self-expanding THVs implanted with commissural alignment
- Outcome
- Unsuccessful coronary cannulation after TAVR
Methodological detailssingle-centre, investigator-driven, consecutive patients
- Single-centre
- Investigator-driven
- Consecutive patients
Main finding
As reported in the abstract
P = 0.26
- Overall unsuccessful coronary cannulation
- 7 (5.5%)
Observational data: associations, not effects.
Secondary outcomes
Failure of left coronary artery cannulation
P = 1.00
Failure of right coronary artery cannulation
P = 0.16

|---|---|---|---|
| Coronary overlap | 5.6 (1.2–25.8) | P = 0.03 | |

- Predictors of unfeasible selective coronary re-engagement on post-TAVR CT angiography: inability to selectively cannulate the right coronary artery; not in ACURATE recipients (P = 0.39)
