Chimney Stenting vs BASILICA for Prevention of Acute Coronary Obstruction During Transcatheter Aortic Valve Replacement

JACC Cardiovasc IntervPublished

  • Multicentre observational registry
  • consecutive patients

Authors' conclusion

Chimney stenting and BASILICA effectively prevent TAVR-induced acute CO. Both techniques seem to have comparable acceptable periprocedural and 1-year outcomes.

Study context

Population
Transcatheter aortic valve replacement (TAVR) patients at high risk of coronary obstruction
Participants

Exposure
Chimney stenting vs BASILICA

  • BASILICAn = 97
Outcome
MACE:
  • Death
  • MI
