Cardiology AdvisorOlder Patients Benefit From Patent Foramen Ovale Closure After Ischemic Stroke

This retrospective Medicare claims analysis demonstrates significant efficacy of transcatheter PFO closure in patients over 60 years, extending evidence beyond current guideline recommendations. The study utilized propensity score matching to balance cohorts and evaluated 3-year outcomes in 5,508 matched patients, addressing a critical evidence gap for older stroke survivors.

⚕️ Key Clinical Considerations ⚕️

• Significant stroke reduction: 38% relative risk reduction for recurrent ischemic stroke (HR 0.62, 95% CI 0.44-0.88, P=.007) maintained at 3 years post-intervention.
• Mortality benefit observed: All-cause mortality reduced by 42% (HR 0.58, 95% CI 0.46-0.74, P<.001) suggesting broader cardiovascular protective effects.
• Early safety profile: 30-day complications include venous thromboembolism (1.49% increase), atrial fibrillation (0.77% increase), and major bleeding requiring transfusion (<0.97% increase).
• Frailty consideration: High-risk frail patients showed no significant benefit (HR 1.04, 95% CI 0.60-1.82), indicating need for careful patient selection.
• Real-world applicability: Medicare claims data reflects actual clinical practice patterns but relies on single diagnostic codes for PFO/ASD identification.

🎯 Clinical Practice Impact 🎯

• Patient Communication: Counsel older stroke patients that PFO closure extends beyond traditional age recommendations with demonstrated long-term benefits, while emphasizing importance of individualized risk-benefit assessment based on frailty status and overall health trajectory.
• Practice Integration: Consider expanding PFO closure evaluation protocols to include patients over 60 years, incorporating frailty assessments and multidisciplinary stroke team consultation to optimize patient selection and timing of intervention.
• Risk Management: Implement enhanced 30-day monitoring protocols for venous thromboembolism, cardiac arrhythmias, and bleeding complications, with clear patient education regarding early warning signs and prompt medical attention.
• Action Items: Develop institutional protocols for older adult PFO closure candidates, establish collaboration pathways between neurology and interventional cardiology, and create patient decision aids addressing age-specific considerations and expected outcomes.
