AbstractThe patent foramen ovale is almost a normal anatomical hole between the atria with ~30% incidence in the general population. It has been suggested that the patent foramen ovale is the cause of some neurological events, which is explained by paradoxical embolism. Transcatheter closure of the patent foramen ovale is a common procedure in adult patients with cerebral ischaemic events, but there are limited data investigating the results in children. Between January, 2005 and February, 2014, 17 patients’ patent foramen ovales were closed by the transcatheter approach in our department. The indications for closure were transient ischaemic attack in 10 patients, stroke in four patients, and migraine in three patients. The mean age and mean weight at the time of the procedure were 11.1±3.7 years and 42.1±15.4 kg, respectively. We asked our patients whether their previous ailments continued. All patients responded to the study survey. In 15 patients, ailments did not continue after patent foramen ovale closure and they significantly decreased in two of them. We suggest that under the right conditions device closure of the patent foramen ovale is a safe solution for these cryptogenic ischaemic events and migraine.

: Cryptogenic stroke and its relation to the Patent Foramen Ovale (PFO) is a long-debated topic. Recent clinical trials have unequivocally established the relationship between cryptogenic strokes and paradoxical embolism across the PFO. This slit-like communication exists in everyone before birth, but most often closes shortly after birth. PFO may persist as a narrow channel of communication between the right and left atria in approximately 25-27% of adults. : In this review, we examine the clinical relevance of the PFO with analysis of the latest trials evaluating catheter-based closure of PFO’s for cryptogenic stroke. We also review the current evidence examining the use of antiplatelet medications versus anticoagulants for stroke prevention in those patients with PFO who do not qualify for closure per current guidelines.

Introduction: Patent foramen ovale (PFO) is more commonly found in patients with cryptogenic stroke and paradoxical embolism is commonly assumed to be the primary mechanism. Our objective was to determine the frequency of hypercoagulability in cryptogenic stroke patients and PFO. Methods: Consecutive patients with embolic stroke of undetermined source (ESUS) seen at the Emory Clinic from January 1, 2017 to June 30, 2019 who underwent echocardiogram with bubble study and markers of coagulation and hemostatic activation (MOCHA) testing (serum d-dimer, prothrombin fragment 1.2, thrombin-antithrombin complex, fibrin monomer) were included; abnormal MOCHA was defined as ≥ 2 elevated markers. Venous thromboembolism, malignancy, other defined hypercoagulable state, and the composite outcome were assessed at routine follow-up and compared across groups based on PFO status. Results: Of 172 patients (mean age 63 ± 16 years, 60% female), 40 (23%) had a PFO. Compared to the PFO- group, the PFO+ group was younger (p=<0.001), less likely to have hypertension (p<0.001) and diabetes (p=0.011), and had a higher ROPE score (p=0.007) (Table 1). There was no difference in the frequency of abnormal MOCHA between groups and the composite outcome was less frequent in PFO+ versus PFO- patients (p=0.017). In the subgroup of patients <60 years old, there was no difference in the frequency of abnormal MOCHA and the composite outcome. Conclusion: Hypercoagulability as measured by MOCHA was not associated with the presence of PFO in ESUS patients. Based on our results, ESUS patients should undergo a detailed evaluation for alternative causes of stroke other than paradoxical embolism.
