Key result
Transcatheter PFO closure case reveals unintentional extraction of entrapped Eustachian valve tissue via delivery cable.
Why the study?
Persistent redundant Eustachian valve can interfere with Amplatzer PFO occluder placement, posing anatomical and technical challenges.
Case Report (n=1)
A prominent Eustachian valve can interfere with transcatheter PFO closure, potentially leading to tissue entrapment and unintentional extraction.

Prominent Eustachian valve may complicate PFO closure via tissue entrapment; case report leaves open need for preprocedural imaging strategies.
A 28-year-old man with patent foramen ovale and a prominent Eustachian valve with a history of transient ischemic attack underwent transcatheter closure using Amplatzer patent foramen ovale occluder. During deployment, some of the prominent valve tissue was entrapped on the delivery cable and a piece of the valve was extracted unintentionally. Anatomico-clinical and technical implications are discussed.

Onorato et al. (2002) conducted a case report in Patent foramen ovale and prominent Eustachian valve with history of transient ischemic attack (n=1). Transcatheter closure using Amplatzer patent foramen ovale occluder was evaluated. Transcatheter closure using an Amplatzer patent foramen ovale occluder in a 28-year-old man resulted in unintentional extraction of prominent Eustachian valve tissue entrapped on the delivery cable.
