Clinical Utility of Transcatheter PFO Exploration in Cryptogenic Stroke Patients With Negative TEE but High Suspicion of PFO‐Related Etiology

TEE, though the gold standard for PFO diagnosis, carries a non‑negligible false‑negative rate. In CS patients with negative TEE but high suspicion of PFO-related etiology, TPFOE demonstrated potential as an adjunctive technique to increase PFO detection. Further studies are warranted to better define its diagnostic value for PFO in this patient population.
