Closure of a patent foramen ovale did not prevent recurrent strokes, but detecting atrial fibrillation led to successful anticoagulant therapy and symptom resolution.
Prolonged monitoring for atrial fibrillation is crucial in patients with cryptogenic stroke, even after PFO closure, as its detection significantly alters therapeutic strategy and prevents recurrence.

Cryptogenic stroke is an ischemic stroke of unknown cause after a comprehensive diagnostic workup and accounts for a significant percentage of all strokes. This paper presents the case of a 37-year-old female patient with recurrent ischemic strokes, in whom a patent foramen ovale (PFO) was diagnosed and subsequently closed via catheter-based intervention. Despite this therapeutic procedure, further recurrences occurred. During electrophysiological evaluation and ablation of paroxysmal supraventricular tachycardia, paroxysms of atrial fibrillation were detected, leading to the initiation of anticoagulant therapy. During follow-up, the patient remained free of symptomatic recurrences. This case highlights the importance of prolonged monitoring for the detection of atrial fibrillation in patients with cryptogenic strokes, which can significantly influence therapeutic strategies and recurrence prevention.
