Device Embolization After Transcatheter Patent Foramen Ovale Closure: The Importance of Tunnel Width Assessment.

ABSTRACT:

Background

Patent foramen ovale (PFO) is associated with cryptogenic stroke. Guidelines recommend PFO closure over medical therapy in patients aged 18 to 60.

Case summary

A 40-year-old woman underwent PFO closure at an outside institution, which was complicated by device embolization. Using three-dimensional (3D) transesophageal echocardiography (TEE) to assess PFO tunnel width revealed a larger PFO and guided closure with a 35-mm occlusion device instead of a 25-mm device.

Why beyond the guidelines

Manufacturer guidelines recommend PFO occlusion device sizing based on tunnel length, which resulted in inappropriate sizing. This report presents the use of PFO tunnel width for device sizing.

Discussion

This case report highlights the importance of 3D TEE assessme
