    Transseptal thrombus across a patent foramen ovale (TSFO) is a rare but critical finding associated with paradoxical embolism.

  • 2

    An 81-year-old woman presented with acute dyspnea and was diagnosed with TSFO using contrast-enhanced cardiac CT.

  • 3

    Initial transthoracic echocardiography did not reveal any intracardiac thrombus, highlighting TSFO's transient nature.

  • 4

    Anticoagulation therapy was chosen as the optimal management strategy, leading to significant symptom improvement.

  • 5

    Follow-ups indicated sustained clinical stability and no recurrence of thromboembolic symptoms over two years.
