Percutaneous closure of the patent foramen ovale (PFO) can be accomplished within 15 minutes using only fl uoroscopy for guidance. Local anesthesia and femoral vein puncture in the groin with a 9 French catheter can achieve about a 90% complete closure rate when the Amplatzer® PFO Occluder is used. Complications are extremely rare and physical restrictions are unnecessary starting a couple of hours after the intervention. Aspirin and clopidogrel (Plavix) are typically prescribed for a few months after the procedure, and the therapy concludes with transesophageal echocardiography at follow-up approximately 6 months later.
