Coronary disease & ACSCohort study
Contemporary Trends and Outcomes of Intravascular Lithotripsy in Percutaneous Coronary Intervention
- Registry-based observational cohort study
- multicentre
- 48 Michigan hospitals
Authors' conclusion
Since its introduction in February 2021, coronary IVL use has steadily increased, exceeding atherectomy use in Michigan by February 2022. Contemporary use of IVL and atherectomy is generally associated with high rates of procedural success and low rates of complications.
Study context
- Population
- All Percutaneous Coronary Intervention (PCIs) at 48 Michigan hospitals, January 1, 2021 – June 30, 2022
- Participants
- 1,090 / 1,743 / 240
- Exposure
- Intravascular lithotripsy (IVL) vs atherectomy in PCI
- IVLn = 1,090
- Atherectomyn = 1,743reference
- Bothn = 240
- Outcome
- In-hospital MACE and procedural success
- Follow-up
- In-hospital
Main finding
As reported in the abstract
Use of IVL and atherectomy; in-hospital MACE and procedural success
Use of IVL and atherectomy; in-hospital MACE and procedural success
MACE IVL 4.3% · Atherectomy 5.4% · P = 0.23
Procedural success IVL 89.4% · Atherectomy 89.1% · P = 0.88
Observational data: associations, not effects.
Further findings
- IVL patients similar to pivotal IVL trial populations (subgroup)
- 15.6% · 169 of 1,090
IVL patients similar to pivotal IVL trial populations (subgroup)
- Outcomes similar to those reported in the pivotal IVL trials
