• Life expectancy < 4 years.

Egyéb

• mRS > 3.
• PFO associated with an atrial septal defect (ASD) requiring closure (significant shunt with impact on the right cavities, elevation of pulmonary pressures or QP/QS>2)
• Patient unable to understand the informed consent form. Patient under tutorship, curatorship, or legal protection.

• Man or woman aged 60 to 80 years.
• Recent (≤ 6 months) ischemic stroke confirmed by cerebral imaging regardless of symptom duration.

• Presence of a PFO with at least 1 of the 2 following characteristics:
  • PFO with large shunt (> 20 microbubbles) appearing in the left atrium during at least one of the 3 cardiac cycles after complete opacification of the right atrium, detected either spontaneously or during provocative manoeuvers, on contrast transthoracic (TTE) or transoesophageal (TOE) echocardiography. The diagnosis of PFO by contrast TEE must be confirmed by contrast TOE showing a right-to-left passage of the contrast material across the PFO.
