“…It is possible that we underestimated the true prevalence of PFO. One study showed that TEE is less sensitive in detection of PFO than gentle attempts to cross the interatrial septum with the use of steerable catheter during the PVI procedure [17]. However, the prognostic importance of small PFO that does not manifest in TEE during Valsalva manouver might be different from importance of a more "manifest" PFO -as investigated in our population.…”

“…Similar mechanism can be operative in the pathogenesis of AF occurrence/recurrence as it is possible that influx of venous blood into the LA in patients with PFO delivers to LA biologically active substances that may predispose to AF initiation or progression of atrial myopathy. Indeed, in a recent work Daher et al found an increased prevalence of PFO reaching 57% in AF patients referred for PVI [17].…”

“…Daher et al, reported patent foramen ovale prevalence of 18.7% using TEE and 56.6% during the pulmonary vein isolation ablation procedure in AF patients. 11 As a structured congenital heart disease, patent foramen ovale is also linked to AF. Atrial arrhythmias increase with increasing age to up to 38% in 50-year-old patients.…”

Abstract. Background: Patent foramen ovale (PFO) is a major cause of cryptogenic stroke (CS). However, it is still possible that PFO comes with those other conditions during evaluation. This paper presents a series of CS cases highly suspected due to PFO origin with each of its special presentations. Case illustration/summary of a review article: We present three cases of CS with PFO as a possible contributing factor. Case 1 showed a patient with repeated ischemic strokes that was investigated to be cryptogenic in origin. Case 2 showed CS with PFO and occult atrial fibrillation. Case 3 showed CS at a young age caused by a PFO with protein C/S deficiency. Conclusion: The role of PFO as a culprit, risk factor, or a coincidental finding in CS is still debatable and is a controversial issue. Determining PFO as a cause of CS requires a thorough consideration of clinical and PFO anatomical/morphological factors.

“…At least two studies have documented that catheter probing performed during pulmonary vein isolation procedures has a 2-3-fold higher PFO detection yield than transesophageal echocardiography (TEE) [4][5][6]. We hypothesized in 2020 that AF may more common in patients with PFO [6].…”

“…Since a PFO is present in ~25% of the population [9], it is surprising that Kielbasa et al [1] found a PFO in only 12.7% of their patients, relying on TEE for diagnosis. Daher et al [5] reported that among AF patients referred for PVI, 57% had a PFO identified by catheter probing, but only 18.7% of patients had a PFO diagnosed by TEE. Small PFOs are less likely to be identified with echocardiography.…”
