Retrospective Case

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.

Pfo Closure

Background and Purpose: Recent several studies demonstrated that percutaneous patent foramen ovale (PFO) closure reduced the risk of stroke recurrence for patients with cryptogenic stroke (CS) and PFO. Our aim of this retrospective study is to survey the frequency of CS, which can be an indication of PFO closure. Methods: Subjects were consecutive stroke patients with symptomatic ischemic lesion detected by magnetic resonance imaging. Of them, CS were extracted according to exclusion of small-vessel collusion, large-artery atherosclerosis, cardioembolism, definite case of aortogenic embolism, and distinctive causeof ischemic stroke such as arterial dissection, hypercoagulable state and so on. After that, we selected patients in accordance with clinical guideline of PFO closure recommended by the Japanese Stroke Association (Figure). We analyzed the prevalence of CS with right-to-left shunt (RLS) as a good and recommended candidates for PFO closure. Results: Among 1,374 ischemic stroke patients from October 2012 to September 2019 , CS were 240 patients (83 females, mean age of 66 years, 17% of subjects). Of them, 100 patients (42%) had RLS (PFO; 65, atrial septal defect; 1, pulmonary arteriovenous fistula; 1, positive on transcranial Doppler (not performed in TEE) including 21 cases of definite of paradoxical embolism. In 65 patients of CS with PFO, 30 patients younger than 60 years (13% of CS) were good candidates for PFO closure. Moreover, 22 of 1,374 (1.6%) patients who were recommended candidates had one or more high risk factors of PFO, for example large shunt, atrial septal aneurysm, and the presence of shunt at rest (Figure). Conclusions: In our preliminary survey, 2% of acute ischemic stroke should be PFO closure candidates.

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.

Abstract Background Percutaneous closure of patent foramen ovale (PFO) is routinely performed using plain fluoroscopy in the catheter room. This method results in inevitable radiation damage, adverse effects of contrast agents on kidneys, and high cost. We performed PFO closure with a simplified and economical transesophageal echocardiography (TEE)-only guided approach in the operating room. This study aimed to investigate the feasibility, safety, and effectiveness of the percutaneous closure of PFO by only using TEE. Methods We reviewed the medical records of patients who underwent percutaneous PFO closure at our center from December 2013 to December 2017. A total of 132 patients with PFO and cryptogenic strokes underwent PFO closure by using cardi-O-fix PFO device under TEE guidance. The participants comprised 64 and 68 male and female patients, respectively. The mean age and body weight of the patients were 39.40 ± 13.22 years old (12–68 years old) and 65.42 ± 9.70 kg (40–95 kg), respectively. All patients only received aspirin (3–5 mg/kg body weight, oral administration) for 6 months. Contrast-enhanced transthoracic echocardiography (c-TTE) with Valsalva maneuver was performed during follow-up, and questionnaire surveys were obtained at 3, 6, and 12 months after the procedure. Results All (100%) patients were successfully closed. Follow-ups were conducted for 13 months to 48 months, with an average of 27 months. No severe complications were found during the follow-up period. Paroxysmal atrial fibrillation occurred in 4 patients within 3 months after the procedure. No recurrent stroke or death occurred in all patients during the follow-up period. Transient ischemic attack occurred in one patient 6 months after the procedure. Ten (7.6%) patients had a right-to-left shunt, as demonstrated by c-TTE at 12 months of follow-up. Among the 57 patients suffering from migraine, significant relief or resolution was reported by 42 (73.7%) patients. Conclusion TEE-only guided PFO closure was a safe, feasible, and effective method that did not require the use of X-rays and contrast agents.

Abstract Introduction The prevalence of patent foramen ovale (PFO) in the general population is high (25%). In patients with cryptogenic stroke (CS) and PFO, determining whether it is causally related to stroke or is an incidental finding is a controversial issue. The RoPE score was described in 2013 to predict the likelihood that the stroke was related to the PFO. The higher the score, the greater the risk of attributable causality, considering 6 as the cut-off point. This scale includes clinical variables, but does not consider the echocardiographic characteristics of PFO that were used as inclusion criteria in studies that have shown benefit with percutaneous closure, such as the complex anatomy of PFO (extensive passage of microbubbles across the PFO at rest and/or interatrial septum aneurysm). Purpose Our aim was to investigate the association of the RoPE score with recurrence of stroke in a series of patients with CS and percutaneously closed PFO in a period of time prior to the current recommendations, as well as to describe the presence of complex anatomy of PFO and its relationship with the value of that score. Methods A series of 172 consecutive patients with CS and percutaneous closure of PFO, included from January 2001 to November 2014 in a single center was analyzed, and the RoPE score was calculated retrospectively in each patient. The presence of complex anatomy of the PFO was estimated by echocardiography, and the rate of recurrence of stroke and the relationship of both variables with the value of the RoPE score was investigated. Results Of the 172 patients in the series, it was possible to calculate the RoPE score in 150 (87%) of them, which constitute the study sample. The mean age was 46 years (range 17-78), 60% were male, 21% were hypertense, 6% diabetic and 27% smokers. A history of previous stroke was present in 3% of patients and 11% had an imaging study with cortical infarction. RoPE score was ≥6 in 69% of the sample, and 66% of the patients presented complex anatomy of PFO, without significant differences between those with RoPE score ≥6 and <6 (65% versus 70%, p = 0.62). Acute complications (mortality, cardiac tamponade, stroke, device embolism) related to closure of the PFO were not observed. After 17.5 years of maximum follow-up (mean 9.6 ± 3.7 years, no patients lost, with a total of 1441 patients-years of observation), 6 patients presented a stroke. The recurrence rate of stroke was very low in both groups of patients, either with RoPE score ≥6 or <6 (0.4 versus 0.5 per 100 patients/year, p = 0.87). Conclusions In our center, before the current recommendations of PFO closure associated with CS, most of the patients had a RoPE score≥6. The majority of patients presented a complex anatomy of the PFO and the incidence of stroke recurrence was very low, independently of the value of the RoPE score.
