The percutaneous intervention involved (a) Transesophageal ultrasound showing PFO; (b) guiding the contrast catheter to the interatrial septum with a soft-tip guidewire under transesophageal ultrasound monitoring; (C) passing the guidewire through the PFO; (d) placing the guidewire into the left superior pulmonary vein; (e) exchanging the contrast catheter for the occluder delivery sheath; (f) withdrawal of the soft-tip guidewire; (g) passing the occluder along the delivery sheath to the left atrium, releasing the left atrial umbrella; (h) retracting the delivery sheath to release the right atrial umbrella; (i) Traction testing was used to confirm good fixation of the occluder; (j) Release PFO occluder. All key steps in the diagram are pointed out with green arrows. PFO, patent foramen ovale; RA, right atrium; LA, left atrium; LSPV, left superior pulmonary vein.
