Insights
The Impella device shows safety and efficacy in high-risk PCI procedures. However, cardiogenic shock patients treated with Impella experienced higher mortality than seen in other registries, warranting further study.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Impella is a percutaneous mechanical circulatory support device.
- Used for treating cardiogenic shock (CS) and high-risk percutaneous coronary interventions (HR-PCIs).
- IMPELLA-PL is a national retrospective registry in Poland (2014-2021).
Purpose of the Study:
- Evaluate the real-world efficacy and safety of Impella.
- Compare IMPELLA-PL data with other international registries.
- Analyze outcomes for CS and HR-PCI patients.
Main Methods:
- Retrospective analysis of 308 patients from the IMPELLA-PL registry.
- Primary endpoints: in-hospital mortality and 12-month mortality/MACCE.
- Data collected from 20 Polish interventional cardiology centers.
Main Results:
- In-hospital mortality: 76.4% for CS vs. 8.3% for HR-PCI.
- 12-month mortality: 80.0% for CS vs. 18.2% for HR-PCI.
- Complication rates varied, with higher bleeding in CS patients.
Conclusions:
- Impella demonstrates safety and effectiveness in HR-PCIs.
- CS patients had higher risk profiles and mortality compared to other registries.
- Further investigation is needed to understand Impella's benefits in CS.
Background:
Impella is a percutaneous mechanical circulatory support device for treatment of cardiogenic shock (CS) and high-risk percutaneous coronary interventions (HR-PCIs). IMPELLA-PL is a national retrospective registry of Impella-treated CS and HR-PCI patients in 20 Polish interventional cardiological centers, conducted from January 2014 until December 2021.
Aims:
We aimed to determine the efficacy and safety of Impella using real-world data from IMPELLA-PL and compare these with other registries.
Methods:
IMPELLA-PL data were analyzed to determine primary endpoints: in-hospital mortality and rates of mortality and major adverse cardiovascular and cerebrovascular events (MACCE) at 12 months post-discharge.
Results:
Of 308 patients, 18% had CS and 82% underwent HR-PCI. In-hospital mortality rates were 76.4% and 8.3% in the CS and HR-PCI groups, respectively. The 12-month mortality rates were 80.0% and 18.2%, and post-discharge MACCE rates were 9.1% and 22.5%, respectively. Any access site bleeding occurred in 30.9% of CS patients and 14.6% of HR-PCI patients, limb ischemia in 12.7% and 2.4%, and hemolysis in 10.9% and 1.6%, respectively.
Conclusions:
Impella is safe and effective during HR-PCIs, in accordance with previous registry analyses. The risk profile and mortality in CS patients were higher than in other registries, and the potential benefits of Impella in CS require investigation.
