PFO Closure – Frequently Asked Questions
What is a PFO and does everyone with a PFO need treatment?
A patent foramen ovale (PFO) is common and often harmless. Most people with a PFO never need treatment. PFO closure is considered only when the PFO is thought to be clinically relevant. Determining this often requires individualized review of imaging and clinical history.
When is PFO closure usually considered?
PFO closure is most commonly considered after an embolic stroke or transient ischemic attack when no other clear cause has been identified. Whether this applies in an individual case often becomes clear only after structured reassessment.
Can PFO closure be considered even if there are other possible stroke causes?
Yes. The presence of additional stroke mechanisms does not automatically exclude PFO closure. In borderline situations, careful case-by-case evaluation is essential to determine whether paradoxical embolism remains the most plausible explanation.
Is age a strict limitation for PFO closure?
No. Age alone should not be the deciding factor. In practice, many patients are declined based on age without full individualized assessment. A second opinion can help clarify whether age is truly relevant in a given case.
What if I was told elsewhere that PFO closure is not indicated?
This is a common reason patients contact us. Decisions based purely on checklists may overlook individual anatomical or clinical factors. A structured second opinion may help clarify available options.
What if my PFO closure elsewhere was unsuccessful or left a residual shunt?
Residual shunts require careful reassessment. The appropriate next step depends on the initial technique, anatomy, symptoms, and patient-specific factors. These situations often benefit from expert review.
Are there alternatives to metal-containing PFO devices?
Yes. Depending on anatomy and clinical context, suture-based or bioresorbable closure concepts may be considered. Whether these options are suitable can only be determined after individual evaluation.
Do I need lifelong medication after PFO closure?
No. Antiplatelet medication is usually prescribed for a limited period. The optimal regimen depends on individual medical history and other conditions and should be discussed in the context of the overall treatment strategy.
Can I undergo MRI after PFO closure?
Yes. Modern PFO closure techniques are MRI compatible. The details depend on the closure method and device used and can be clarified during consultation.
When can I return to normal activities and travel?
Most patients can resume normal daily activities within one day. Travel is often possible as early as the next day. Individual recommendations depend on the procedure and clinical context.
Can I dive after PFO closure?
If a PFO was considered relevant for diving-related risk, diving should be avoided until evaluation and, if chosen, successful closure have been completed and confirmed. After follow-up, diving is often possible again with individualized recommendations.
Is PFO closure a safe procedure?
In experienced centers, PFO closure is considered a low-risk procedure. Whether the expected benefit outweighs the risks depends on the individual situation and should be discussed personally.
Still unsure whether this applies to you?
If you have questions about PFO closure, were declined elsewhere, or are uncertain whether your situation fits standard criteria, you may request an individual consultation.
