PCI Outcomes in Patients with Prior TAVR: Key Findings from a 2025 Study
PCI Outcomes in Patients with Prior TAVR: Key Findings from a 2025 Study
1. Study Objective:
To evaluate the success and risks of PCI in patients with a history of transcatheter aortic valve replacement (TAVR), using data from the ACC’s CathPCI Registry (2011–2017).
2. Population Studied:
• Over 52,000 Medicare fee-for-service patients who underwent TAVR.
• Among them, 5.1% had PCI within 5 years.
• Compared with >5,000 propensity-matched patients who underwent PCI without prior TAVR.
3. PCI Success Rates:
• PCI success:
• 91.6% in post-TAVR patients
• 92.4% in non-TAVR patients
• No statistically significant difference.
4. Procedural Differences:
• Fluoroscopy time:
• 21.9 minutes (post-TAVR) vs. 17.7 minutes (non-TAVR)
• Post-procedure stroke rate:
• 0.8% (post-TAVR) vs. 0.4%
• Bleeding rate:
• 5.1% (post-TAVR) vs. 2.9%
5. Long-Term Outcomes (3-Year Follow-Up):
• Higher rate of repeat PCI in the TAVR group
• Similar rates of AMI between groups
• Stroke and death were more frequent in post-TAVR patients
6. Technical Challenges in Post-TAVR PCI:
• Difficult coronary engagement
• Limited catheter support, especially with self-expanding valves
7. Possible Explanations for Adverse Outcomes:
• Increased procedural complexity
• Less frequent use of antiplatelets/anticoagulants
• Possible intrinsic bleeding risks in aortic stenosis patients
8. Limitations of the Study:
• All patients were Medicare beneficiaries (limits generalizability)
• Type of TAVR valve not specified
