Background: The antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by a combination of arterial and/or venous thrombosis and recurrent fetal loss, and can be an independent risk factor for a first-ever ischemic stroke especially in young female patients. Patent foramen ovale (PFO) has been established as a cause of cryptogenic stroke. Atrial septal aneurysm (ASA) is associated with PFO. Until recently, the precise pathophysiology of APS as causing ischemic stroke has been essentially unknown. In the present study, we investigated the relationship between APS and potential embolic sources including PFO and ASA using transesophageal echocardiography (TEE). Methods: This study was a retrospective case series design. From July 2006 to June 2008, 120 patients with ischemic stroke who admitted to Juntendo University Hospital underwent TEE. In this study period, consecutive ischemic stoke patients diagnosed as APS based on the modified Sapporo criteria were enrolled and classified into APS group. Controls were selected among age- and gender-matched stroke patients without APS who also underwent TEE. We assessed clinical characteristics and presence of embolic sources including PFO and atrial septal aneurysm (ASA) between APS and Control groups. Results: Nine of ischemic stroke patients with APS and 41 controls were included. Primary APS was present in one patient (11.1%) of the APS group, and APS with SLE were found in eight patients (88.9%). There is no significant difference in age, risk factors for ischemic stroke, and MRI findings between two groups. The prevalence of PFO and ASA were significantly higher in APS group compared to Control group (89% vs 41%, P=0.027; 67% vs 20%, P=0.015, respectively). C reactive protein was relatively higher in APS group. Multiple logistic regression analysis showed that PFO (OR: 13.71; 95% CI: 1.01 to 185.62; P=0.049) and ASA (OR: 8.06; 95% CI: 1.17 to 55.59; P=0.034) were independently associated with the APS group. Conclusion: Atrial septal abnormalities including PFO and ASA are strongly associated with APS group, and could be potential embolic sources in ischemic stroke patients with APS.

SummaryPatent foramen ovale (PFO) is a potential cause of cryptogenic stroke, given the possibility of paradoxical embolism from venous to systemic circulation. D-dimer level is used to screen venous thrombosis. We investigated the risk of embolism and mortality according to the presence of PFO and D-dimer levels in cryptogenic stroke patients. A total of 570 first-ever cryptogenic stroke patients who underwent transesophageal echocardiography were included in this study. D-dimer was assessed using latex agglutination assay during admission. The association of long-term outcomes with the presence of PFO and D-dimer levels was investigated. PFO was detected in 241 patients (42.3 %). During a mean 34.0 ± 22.8 months of follow-up, all-cause death occurred in 58 (10.2 %) patients, ischaemic stroke in 33 (5.8 %), and pulmonary thromboembolism in 6 (1.1 %). Multivariate Cox regression analysis showed that a D-dimer level of > 1,000 ng/ml was an independent predictor for recurrent ischaemic stroke in patients with PFO (hazard ratio 5.341, 95 % confidence interval 1.648–17.309, p=0.005), but not in those without PFO. However, in patients without PFO, a D-dimer level of > 1,000 ng/ml was independently related with all-cause mortality. The risk of pulmonary thromboembolism tended to be high in patients with high D-dimer levels, regardless of PFO. Elevated D-dimer levels in cryptogenic stroke were predictive of the long-term outcome, which differed according to the presence of PFO. The coexistence of PFO and a high D-dimer level increased the risk of recurrent ischaemic stroke. The D-dimer test in cryptogenic stroke patients may be useful for predicting outcomes and deciding treatment strategy.

The aim of this study was to investigate the prevalence of patent foramen ovale (PFO) in a consecutive unselected cohort of migraine patients (with and without aura) and compare it with a group of ischaemic young and elderly stroke patients. One hundred and forty-one migraine patients were compared with 330 stroke patients (130 young patients; 200 elderly patients) selected from our hospital stroke data bank. PFO was assessed with transcranial Doppler sonography with i.v. injection of agitated saline. The prevalence of PFO was 51.7± in migraine with aura (MA) patients, 33.7± in migraine without aura (MoA) patients, 33.8± in young stroke patients and 20.5± in elderly stroke patients ( P < 0.001). The prevalence of PFO in cryptogenic stroke in young and elderly stroke patients was, respectively, 41.1± and 25± ( P = 0.04). The difference between MA and MoA patients was significant (odds ratio = 2.1). The prevalence of PFO in MA patients is higher than in MoA patients and in young cryptogenic stroke patients.

Abstract Background Research indicates that abnormal embolism caused by patent foramen ovale (PFO) may play an important role in cryptogenic stroke (CS). However, most researches has focused on young patients, and whether abnormal embolism caused by PFO also plays an important role in elderly CS is uncertain. The purpose of this study is to analyze the clinical characteristics of elderly patients with PFO, and to explore the correlation between elderly PFO and ischemic stroke.Methods 62 elderly patients diagnosed with ischemic stroke admitted to Qilu Hospital of Shandong University from April 2014 to April 2019 were selected as the Test Group. 62 non-stroke patients in our hospital's physical examination center and outpatient clinic were selected as the Control Group. Collect clinical data of patients for retrospective analysis.Results The incidence of PFO in the Test Group was significantly higher than that in the Control Group, the difference was statistically significant (p < 0.05). The proportion of large and medium shunt patients in the Test Group was significantly higher than that in the Control Group (p < 0.05). The proportion of patients with migraine in the PFO (+) group in the Test Group was significantly higher than the stroke patients in the PFO (-) group (p < 0.05).Conclusions The shunt volume of the PFO is related to ischemic stroke and may be a risk factor for ischemic stroke.

Background: Numerous studies in adults have reported a robust association between patent foramen ovale (PFO) and cryptogenic arterial ischemic stroke (AIS), particularly in younger adults. The association between PFO and stroke in children has not been well characterized and the clinical significance of identifying a PFO in a child with first or recurrent cryptogenic stroke is currently unknown. Methods: We performed a retrospective case control analysis of a 10-year prospectively enrolled cohort of children with acute AIS who underwent transthoracic echocardiogram (TTE) as part of their diagnostic evaluation. We compared PFO prevalence in children with cryptogenic stroke to those with known stroke etiologies and to non-stroke controls. We also assessed stroke recurrence risk in children with vs without PFO and assessed PFO features that may confer higher stroke risk. Results: Of 119 children with first-ever AIS, 59 had TTE available for central review, of which 17 were cryptogenic and 42 had a known cause. PFO prevalence was higher in the cryptogenic stroke group (X, 24%) compared to both the known stroke etiology group (Y, 6%, p = 0.05) and non-stroke controls (Z, 8%, p = 0.05). However, 2 year recurrence free survival rates in stroke patients with PFO did not differ from those without PFO (HR 1.58, 95% CI 0.18-13.62, p = 0.68). PFOs in children with AIS vs controls had numerically more right-to-left shunt at rest (7 vs 0) and atrial septal aneurysm (4 vs 0) but the study was underpowered to look at these factors. Conclusions: In our prospectively enrolled cohort of children with AIS, we found the prevalence of PFO to be higher in children with cryptogenic stroke compared to healthy controls and non-cryptogenic stroke patients. The implication of PFO for risk of recurrence and optimal secondary preventative treatment remains uncertain and require further study.

AbstractBackgroundTreatment of patent foramen ovale in young patients with stroke is not supported by robust scientific evidence. In clinical practice, a pragmatic approach is needed to guide such therapeutic decisions. This study aims at standardising the diagnostic pathway for stroke patients younger than 55 years of age with a patent foramen ovale; elaborating a therapeutic algorithm; discussing every case in regular interdisciplinary counselling meeting; and setting up a follow-up schedule to assess clinical outcomes.MethodsThis is a cohort study on the effect of a standardised treatment of stroke patients with a patent foramen ovale. The primary endpoints include occurrence of recurrent ischaemic events, major bleeding, and device-related complications. The secondary endpoints include drug- or procedure-related side effects, persistence of right-to-left shunt, and persistent cardiac arrhythmia of new onset.ResultsA total of 103 patients have been enrolled. In all, 51 patients underwent percutaneous atrial septal repair; of these, one had minor post-procedural bleeding. At 12 months, 25% of this group of patients showed a latent I grade shunt, one patient a latent II degree shunt, and none had a persistent shunt. The remaining 52 patients were addressed to medical therapy; one of them experienced stroke recurrences while on medical therapy.ConclusionsThis model of implementation of available evidence to clinical practice via a group-based, multi-disciplinary counselling provides a shared and coherent decision pathway and yielded a very low rate of recurrent events and therapy-related complications. This approach could be replicated in specific protocols for other complex or neglected clinical problems.
