Application of Transesophageal Echocardiography in Amplatzer Atrial Septal Defect Occluder for Percutaneous Closure of Large Patent Foramen Ovale

<div>Implantation of the ASD device under TEE guidance. (a) The left height of the PFO after VM was 3 mm. (b) TEE displaying the 8 mm PFO-SD when the delivery sheath passed the PFO. (c) TEE displaying the proper shape and position of the 14 mm ASD device. ASD: atrial septal defect; SD: stretch diameter; PFO: patent foramen ovale; TEE: transesophageal echocardiography; VM: Valsalva maneuver.</div>
