Summary
A patent foramen ovale (PFO) can cause paradoxical embolism, leading to stroke and other circulatory issues. Percutaneous PFO closure is effective for treating paradoxical embolism and preventing recurrent neurological events.
Area of Science:
- Cardiology
- Neurology
- Vascular Surgery
Background:
- A 38-year-old male presented with angina and dyspnea, 3 months post-ischemic stroke.
- Initial investigations for stroke etiology were inconclusive.
Observation:
- Patient developed left popliteal artery occlusion, treated surgically.
- Subsequent right arm dysesthesia and left carotid artery thrombus were identified.
- Deep vein thrombosis and pulmonary embolism were diagnosed.
Findings:
- Transesophageal echocardiography revealed a patent foramen ovale (PFO) with a significant shunt.
- Percutaneous closure of the PFO with an occluder device was performed successfully.
- No complications or residual shunt were noted post-procedure.
Implications:
- Paradoxical embolism due to PFO is a critical diagnosis in cryptogenic stroke and systemic emboli.
- Interventional PFO closure is the preferred treatment for confirmed paradoxical embolism.
- Successful PFO closure resolved neurological symptoms and prevented recurrence.
