IVUS Use and Long-Term PCI Outcomes in the United States: Insights from the Premier Database—Coverage of CRT 2024

Is there an association between the use of intravascular ultrasound (IVUS) during percutaneous coronary intervention (PCI) and long-term mortality in a large patient population? This study investigated the association between the use of IVUS during PCI and long-term mortality. The researchers examined data from a large healthcare database that included over 2.3 million patients who underwent PCI between 2004 and 2019.

What did the study show?  

The study investigated the association between the use of IVUS during PCI and long-term mortality. Researchers examined data from a large healthcare database that included over 2.3 million patients who underwent PCI between 2004 and 2019. The use of IVUS was relatively uncommon (only 7.65% of cases) but increased modestly over time. There were significant variations in how often IVUS was used between hospitals.

The study found that using IVUS during PCI was associated with a reduced risk of long-term mortality. This remained true even after adjusting for other factors that could influence mortality rates. The findings support previous randomized trials that showed benefits of IVUS use during PCI but extend those results to a broader patient population over a longer period.

Key takeaways

  • Intravascular ultrasound (IVUS) use during percutaneous coronary intervention (PCI) is associated with reduced long-term mortality in a large cohort of patients.
  • The use of IVUS during PCI is still relatively uncommon but has been increasing over time.
  • There is significant variation in how often IVUS is used between hospitals.
  • This study's findings support the results of previous, more controlled trials, suggesting that the benefits of IVUS during PCI may be generalizable to a wider range of patients in real-world practice.
