Case in brief
A 55-year-old man with no significant medical history presented after a cryptogenic ischemic stroke, considered likely related to a patent foramen ovale (PFO). Transesophageal echocardiography showed a complex interatrial septum with a long-tunnel PFO and an incomplete crescent-shaped left atrial membrane consistent with cor triatriatum sinister. Despite these anatomical challenges, a 30 mm GORE Cardioform Septal Occluder was successfully implanted to close the PFO.
What made this case unusual
The combination of a long-tunnel PFO and incomplete cor triatriatum sinister created anatomical challenges for closure; the report describes successful percutaneous closure in this setting.
Diagnostic / clinical pearl
Transesophageal echocardiography can define complex septal and left atrial anatomy relevant to planning PFO closure when congenital anomalies are present.
Why it matters
The case demonstrates the reported feasibility of percutaneous PFO closure despite incomplete cor triatriatum sinister, while underscoring the need to account for the anatomy.
