Management Recommendation for 25-Year-Old Woman with PFO and RoPE Score of 9
This patient does NOT require PFO closure at this time because she has not had a cryptogenic stroke or TIA—she is asymptomatic with an incidentally discovered PFO. 1
Key Clinical Context
Your patient has:
- Incidentally discovered PFO (no stroke history mentioned)
- High RoPE score of 9 (indicating high probability that a PFO would be causally related to stroke if one occurred)
- Normal cardiac function (EF 61%, normal chamber sizes)
- Mildly dilated aortic root (3.2 cm, indexed 2.0 cm/m²—borderline but not severely abnormal for a young woman)
The Critical Distinction: Primary vs Secondary Prevention
All guideline evidence and randomized trial data support PFO closure only for SECONDARY prevention (after cryptogenic stroke), not primary prevention in asymptomatic patients. 1, 2
The 2018 BMJ guideline explicitly states recommendations apply to "patients under 60 years old with patent foramen ovale (PFO) who have had a cryptogenic ischaemic stroke, when extensive workup for other aetiologies of stroke is negative." 1 The Netherlands Society of Cardiology similarly recommends closure "should be considered in patients with transient ischaemic attack or cryptogenic stroke and a RoPE score >8." 1
Screening for PFO for primary prevention is not recommended. 3
What the RoPE Score of 9 Actually Means
While your patient's RoPE score of 9 is high, this score was developed to estimate the probability that a PFO is causally related to a stroke that has already occurred—not to predict future stroke risk in asymptomatic individuals. 2, 4
Research shows that patients with RoPE scores of 9-10 have a 77% prevalence of PFO when they present with cryptogenic stroke, and these patients derive the greatest benefit from closure (90% relative risk reduction). 2, 4 However, this applies only to the post-stroke population.
Current Management Plan
Immediate Actions:
- No intervention required for the PFO itself
- No antiplatelet or anticoagulation therapy needed (she has no indication)
- Counsel the patient that PFO is common (present in 25% of the general population) and most people with PFO never have complications 1, 2
Monitoring Considerations:
- Aortic root surveillance: The mildly dilated aortic root (indexed 2.0 cm/m²) warrants periodic echocardiographic follow-up every 2-3 years to monitor for progression, though this is borderline and may represent normal variation
- No routine PFO follow-up imaging is needed in asymptomatic patients
Patient Education Points:
- The PFO itself requires no treatment unless she develops a cryptogenic stroke
- She should seek immediate medical attention for any stroke-like symptoms (sudden weakness, vision changes, speech difficulty)
- Standard stroke prevention measures apply: maintain healthy blood pressure, avoid smoking, regular exercise
- If she develops migraine with aura or experiences decompression sickness (if she's a diver), re-evaluation may be warranted
Special Circumstances That Would Change Management
Reconsider evaluation if she develops:
- Cryptogenic stroke or TIA → Full workup and likely PFO closure 1
- Platypnea-orthodeoxia syndrome (dyspnea/hypoxemia when upright that improves supine)—the aortic root dilation could theoretically contribute to this rare condition 5
- Plans for high-risk activities (deep-sea diving, high-altitude climbing)
Common Pitfalls to Avoid
- Do not close asymptomatic PFOs based solely on high RoPE scores or anatomical features—this exposes patients to procedural risks (atrial fibrillation, device embolization, aortic injury) without proven benefit 1, 2, 6
- Do not start antiplatelet or anticoagulation therapy in asymptomatic PFO patients—there is no indication 1
- Do not confuse the presence of high-risk anatomical features (which you'd assess with TEE if she had a stroke) with an indication for prophylactic closure
