Multidisciplinary Approach to Patent Foramen Ovale Closure for Cryptogenic Stroke: Brain-Heart Board Experience. Neurol Clin Pract 2024; 14:e200319. [PMID: 38826798 PMCID: PMC11141343 DOI: 10.1212/cpj.0000000000200319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 03/11/2024] [Indexed: 06/04/2024]
Abstract
Background and Objectives Patent foramen ovale (PFO) is present in approximately 25% of adult population. The prevalence of PFO is high in patients with cryptogenic stroke suggesting paradoxical embolism. PFO closure in carefully selected patients is an effective secondary preventive strategy in these patients. We report predictors of management recommendations by the multidisciplinary Board and their impact on outcomes. Methods Brain-Heart Board comprises vascular and interventional neurology and cardiology subspecialties (structural, electrophysiology, and cardiac imaging). Adult patients referred to the Board for consideration of PFO closure between October 2017 to March 2021 were included in this retrospective cohort analysis. Demographics, comorbid conditions, risk of paradoxical embolism (RoPE) score, event frequencies (transient ischemic attack [TIA] or stroke, intracranial hemorrhage [ICH], post-PFO closure cardiac arrhythmias), and modified Rankin Scale (mRS) at 1 year were compared between the groups (PFO closure vs medical management). Multivariable logistic regression was used to identify factors associated with management recommendation and chi-square tests to test differences in outcomes for patients according to management. Results Two hundred seventy patients (229 stroke; 41 TIA) were discussed by the Board for PFO closure. 119 (44.0%) patients were recommended for PFO closure of which 117 (98.3%) had evidence of ischemic infarct on imaging. In univariate analysis, age was similar (50 ± 11.9 vs 52 ± 12.8, p = 0.17), but RoPE score was higher in closure as compared with the medical management group (6 [IQR 5-7] vs 5 [IQR 4-7], p < 0.05). In multivariable analysis, TIA as the index event was an independent predictor of Board recommendation against PFO closure (OR 0.05, 95% CI 0.01-0.19, p < 0.05). Event frequency was low in both cohorts (5.9% vs 4.8%, p > 0.05) and comprised cardiac arrhythmias (6 cases of atrial fibrillation and 1 ICH in closure group; 1 TIA and 1 recurrent stroke in medical management group). Excellent functional outcome (mRS 0-1) was similar in both cohorts (66.3% vs 70.7%, p > 0.05) at 1 year. Discussion Multidisciplinary Brain-Heart Board provides a clinical practice model of collaborative care to ensure proper patient selection for PFO closure. TIA as the index event is associated with recommendation of medical management by the multidisciplinary Brain-Heart Board.

Abstract
Ischemic stroke patients with thrombophilia and patient foramen ovale (PFO) may have an increased risk of recurrent stroke and transient ischemic attack (TIA), and may benefit from PFO closure. However, screening for thrombophilia is not routinely performed and the impact of thrombophilia on prognosis after PFO closure is uncertain. We aim to compare the risk of recurrent stroke and TIA after PFO closure in patients with thrombophilia versus those without. We performed a systematic review and meta-analyses of the literature, with a comprehensive literature search performed on 12 January 2023. Studies comparing the outcomes of patients with and without thrombophilia after PFO closure were included. The primary outcome evaluated was a recurrence of acute cerebrovascular event (ACE), a composite of recurrent ischemic stroke and recurrent TIA. The secondary outcomes included recurrent ischemic stroke only or TIA only. A total of 8 cohort studies were included, with a total of 3514 patients. There was an increased risk of stroke/TIA in patients with thrombophilia compared to those without thrombophilia after PFO (OR: 1.42, 95% CI: 1.01-1.99, I2 = 50%). The association between risk of TIA only (OR: 1.36, 95% CI: 0.77-2.41, I2 = 0%) and stroke only (OR: 1.09, 95% CI: 0.54-2.21, I2 = 0%) with thrombophilia did not reach statistical significance. There is an increased risk of recurrent cerebral ischemia event in patients with thrombophilia compared to those without thrombophilia after PFO closure. Future large prospective studies are necessary to characterise the risk and benefits of PFO closure, as well as the appropriate medical treatment to reduce the risk of recurrent stroke and TIA in this high-risk population.

Abstract
BACKGROUND The advantages of patent foramen ovale (PFO) closure as protection from a recurrence of stroke remains controversial compared to drug therapy, especially in patients over 60 years. HYPOTHESIS The aim of the study is to compare recurrence of stroke in patients over 60 years old with PFO closure versus drug therapy alone. METHODS We included 342 patients over 60 years who suffered a crytopgenic stroke, and were also accepted for a PFO closure. 199 patients refused a PFO closure and were treated with medical therapy alone, whereas 143 patients underwent a PFO closure procedure. RESULTS The mean follow up time was 5.5 ± 1.5 years. All patients in Group B showed persistent shunt in the follow-up period (n = 199, 100%). In Group A, seven patients were diagnosed with residual shunt during echocardiography examination (5%). A new onset of atrial fibrillation occurred in seven patients in Group A (5%) and six patients in Group B (3%), p = .117. Recurrent stroke occurred in 3 patients in Group A (2%) and 11 patients in Group B (6%), p = .021. One patient died of unknown reason (1%) and two patients were lost due to neurological death (1%) in Group B, whereas no patients in Group A died during the follow-up period. CONCLUSION Our results show that strict exclusion of patients over 60 years from PFO closure should be reconsidered. As life expectancies are increasing, patients should be considered for same treatment as younger patients, since the outcomes are improved compared to patients treated with medical therapy alone.

Abstract
BACKGROUND Patent foramen ovale (PFO) is a known cause of ischemic stroke in young adults and combined oral contraceptives (COCs) are widely used by women of reproductive age. If young women with PFO are taking COCs, they may be subjected to a synergistic increase in the occurrence of stroke, though reports of ischemic stroke in this population are rare. We report a woman of reproductive age who was taking COC suffered repetitive ischemic strokes before a patent foramen ovale (PFO) was detected and closed, which may raise concerns in this field. CASE PRESENTATION A 31-year-old woman presented to the emergency department with sudden-onset right upper- and lower-limb weakness and dysarthria for 1 hour, whose only risk factor of stroke was oral contraceptive use. On admission, she was alert with left gaze deviation, dysarthria, and right-sided hemiplegia. Her symptoms improved after receiving the revascularization therapy. About 24 hours later, her left eye experienced sudden painless vision loss. Then the PFO with a substantial right-to-left shunt was detected and then she received a trans-catheter closure of the defect. Over 3 months of follow-up, there were no signs of stroke, but visual loss persisted. CONCLUSION This case of disabling stroke raises concerns regarding optimal management in primary and secondary prevention of stroke in young women on COCs with additional risk factors of stroke.

Abstract
Patent foramen ovale (PFO) is frequently identified in young patients with ischemic stroke. Randomized controlled trials provide robust evidence supporting PFO closure in selected patients with cryptogenic ischemic stroke; however, several questions remain unanswered. This report summarizes current knowledge on the epidemiology of PFO-associated stroke, the role of PFO as a cause of stroke, and anatomic high-risk features. We also comment on breakthrough developments in patient selection algorithms for PFO closure in relation to the PFO-associated stroke causal likelihood risk stratification system. We further highlight areas for future research in PFO-associated stroke including the efficacy and safety of PFO closure in the elderly population, incidence, and long-term consequences of atrial fibrillation post-PFO closure, generalizability of the results of clinical trials in the real world, and the need for assessing the effect of neurocardiology teams on adherence to international recommendations. Other important knowledge gaps such as sex, race/ethnicity, and regional disparities in access to diagnostic technologies, PFO closure devices, and clinical outcomes in the real world are also discussed as priority research topics.

Abstract
The association between cryptogenic stroke (CS) and patent foramen ovale (PFO) with or without atrial septal aneurysm (ASA) has been a debate for decades in terms of pathophysiologic processes and clinical courses. This issue has become more interesting and complex, because of the concerns associating the CS with so-called normal variant pathologies of interatrial septum, namely ASA and PFO. While there is an anatomical pathology in the interatrial septum, namely PFO and ASA, the embolic source of stroke is not clearly defined. Moreover, in patients with PFO and CS, the risk of recurrent stroke has also been associated with other PFOunrelated factors, such as hyperlipidemia, body mass index, diabetes mellitus, and hypertension, leading to the difficulty in understanding the pathophysiologic mechanism of CS in patients with PFO and/or ASA. Theoretically, the embolic source of cryptogenic stroke in which PFO and/or ASA has been involved can be categorized into three different anatomical locations, namely PFO tissue and/or ASA tissue itself, right or left atrial chambers, and venous vascular territory distal to the right atrium, i.e., inferior vena cava and lower extremity venous system. However, the possible role of paroxysmal atrial fibrillation associated with PFO and/or ASA as a source of cryptogenic stroke has never been mentioned clearly in the literature. This review aims to explain the association of cryptogenic stroke with PFO and/or ASA in a comprehensive manner, including anatomical, clinical, and mechanistic aspects. The potential role of paroxysmal atrial fibrillation and its contribution to clinical course have been also discussed in a hypothetical manner to elucidate the pathophysiology of CS and support further treatment modalities.

Abstract
The secondary prophylaxis of ischemic stroke provides an enormous therapeutic potential due to the high frequency of recurrent thrombembolic events and the exceptional importance of modifiable cardiovascular risk factors for the individual risk of stroke. In this respect, anti-thrombotic, interventional and surgical treatment options must be selected based on the respective etiology. Furthermore, meticulous optimization of risk factors is essential for effective long-term care. Close interdisciplinary and intersectoral collaboration is crucial, especially in the long-term treatment.

Abstract
INTRODUCTION Certain patent foramen ovale (PFO) characteristics, such as a large right-to-left shunt (RLS) or atrial septal aneurysm, identify patients who may receive the highest clinical benefit from percutaneous PFO closure. This study aimed to compare intracardiac echocardiography (ICE) with standard echocardiographic imaging in the evaluation of high-risk PFO characteristics and RLS severity in patients with PFO-associated stroke. METHODS We conducted a retrospective review of all patients aged ≥18 years who underwent percutaneous PFO closure for PFO-associated stroke and received all three ultrasound-based cardiac imaging modalities and had interpretable results (N = 51). We then compared RLS severity, high-risk PFO characteristics, and the proportion of patients with a higher likelihood of PFO-associated stroke by ICE versus transthoracic echocardiogram (TTE) and transesophageal echocardiogram (TEE). RESULTS The final cohort had a mean (±SE) age of 48.4 (±1.8) years and was predominantly female (58.8%). ICE was more likely to identify a large RLS versus TTE/TEE combined (66.7% vs. 45.1%; p = 0.03). The use of ICE resulted in significantly more patients being reclassified as having a higher likelihood of PFO-associated stroke (TTE vs. TEE vs. ICE: 10.4% vs. 14.6% vs. 25%; p = 0.03). A high-quality bubble study was found to be the single most important factor associated with identifying a larger RLS across all modalities (ρ [p]; TTE: 0.49 [<0.001], TEE: 0.60 [<0.001], ICE: 0.32 [0.02]). The presence of a hypermobile septum was associated with significantly greater RLS on ICE (ρ [p]: 0.3 [0.03]), especially with poor quality bubble studies (ρ [p]: 0.49 [0.02]). CONCLUSION In this observational study of patients with PFO-associated stroke, ICE detected a large RLS more frequently than TTE and TEE; and reclassified some patients as having a higher likelihood of PFO-associated stroke.

[PMID: 37830692 PMCID: PMC10572775 DOI: 10.3390/healthcare11192655] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 09/23/2023] [Accepted: 09/28/2023] [Indexed: 10/14/2023] Open
Abstract
Traditional diagnosis of patent foramen ovale (PFO) in the heart has involved the use of transcranial Doppler (TCD). However, TCD is essentially a blind test that cannot directly visualize the location of blood vessels. Since TCD relies on qualitative assessments by examiners, there is room for errors, such as misalignment of the ultrasound's angle of incidence with the actual blood vessels. This limitation affects the reproducibility and consistency of the examination. In this study, we presented an alternative approach for assessing right-to-left shunt (RLS) associated with PFO using contrast transcranial color-coded Doppler (C-TCCD) with bubble contrast. The patient under consideration had been diagnosed with an ischemic stroke through imaging, but the subsequent cardiac work-up failed to determine the cause. Employing C-TCCD for RLS screening revealed a confirmed RLS of Spencer's three grades. Subsequently, transesophageal echocardiography (TEE) was conducted to evaluate PFO risk factors, confirming an 8 mm PFO size, a 21 mm tunnel length, a hypermobile interatrial septum, and persistent RLS. The calculated high-risk PFO score was 4 points, categorizing it as a very high risk PFO. This case underscores the importance of C-TCCD screening in detecting RLS associated with PFO, especially in cryptogenic stroke patients, when identifying the underlying cause of ischemic stroke becomes challenging.

J Stroke 2023; 25:338-349. [PMID: 37813671 PMCID: PMC10574307 DOI: 10.5853/jos.2023.01599] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 08/18/2023] [Accepted: 08/21/2023] [Indexed: 10/11/2023] Open
Abstract
Patent foramen ovale (PFO) closure, along with medical therapy, has emerged as the therapeutic gold standard in younger (<60-year-old) patients with a PFO-related stroke for preventing recurrent events. However, PFO management guidelines lack definite recommendations for older (>60 years) patients with a PFO-related cerebrovascular event, a complex group of patients who were mostly excluded from PFO closure clinical trials. Nevertheless, several studies have shown a higher prevalence of PFO among older patients with cryptogenic stroke, and its presence has been associated with an increased risk of recurrent events. Furthermore, older patients exhibit a higher prevalence of high-risk PFO anatomical features, present inherent age-related risk factors that might increase the risk of paradoxical embolism through a PFO, and have a higher incidence of ischemic events after a PFO-related event. Additionally, observational studies have shown the safety and preliminary efficacy of PFO closure in older PFO-related stroke patients. Yet, higher rates of recurrent cerebrovascular events and new-onset atrial fibrillation were observed in some studies among older patients compared to their younger counterparts. After careful case-by-case evaluation, including the assessment of hidden potential cardioembolic sources of a cryptogenic stroke other than PFO, transcatheter PFO closure might be a safe and effective therapeutic option for preventing recurrent thromboembolic events in patients >60 years with a high-risk PFO-associated stroke. Ongoing trials will provide important insights into the role of PFO closure in the elderly population.

Abstract
Introduction The efficacy of patent foramen ovale (PFO) closure in the elderly population is unclear. We aimed to investigate the efficacy and safety of PFO closure in non-elderly and elderly patients. Methods Patients over 18 years of age with cryptogenic stroke (CS) or transient ischemic attack and PFO were prospectively enrolled and classified into two groups according to treatment: (1) closure of PFO (the PFOC group) and (2) medical treatment alone (the non-PFOC group). The primary outcome was a composite of recurrent cerebral ischemic events and all-cause mortality during the follow-up period. A modified Ranking Scale [mRS] at 180 days was recorded. The safety outcomes were procedure-related adverse events and periprocedural atrial fibrillation. The results between the PFOC and non-PFOC groups in non-elderly (<60 years) and elderly (≥60 years) patients were compared. Results We enrolled 173 patients, 78 (45%) of whom were elderly. During a mean follow-up of 2.5 years, the incidence of primary outcome was significantly lower in the PFOC group (6.2% vs. 17.1%, hazard ratio[HR] = 0.35, 95% CI 0.13-0.97, p = 0.043) in adjusted Cox regression analysis. Compared with the non-PFOC group, the PFOC group had a numerically lower risk of the primary outcome in both the elderly (HR 0.26, 95% CI 0.07-1.01, p = 0.051) and the non-elderly (HR 0.61, 95% CI 0.11-3.27, p = 0.574) groups. In addition, patients with PFO closure in the elderly group had a lower median mRS at 180 days (p = 0.002). The rate of safety outcome was similar between the non-elderly and elderly groups. Discussion PFO closure was associated with a reduced risk of the primary outcome in patients with PFO and CS in our total cohort, which included non-elderly and elderly patients. Compared to those without PFO closure, elderly patients with PFO closure had a better functional outcome at 180 days. PFO closure might be considered in selected elderly patients with PFO.

Abstract
INTRODUCTION Here, we described a patient with ischemic stroke due to embolism, through an isolated pulmonary arteriovenous fistula (PAVF). Our case could be a paradigm of embolic stroke of undetermined source (ESUS) with an uncommon cause, providing an etiologic investigation process in addition to diagnostic pitfalls and pearls, eventually raising neurologists' ability to treat ESUS. CASE REPORT A 37-year-old right-handed woman presented to our emergency department with sudden onset left upper limb and lower limb weakness. She denied a past medical history of hypertension, diabetes, heart diseases, and other cerebrovascular disease risk factors, and she is without a family history of stroke, previous trauma, toxic exposure, or drug use. On admission, her physical and neurological examinations were negative, except for left-sided hemiparesis. Her routine evaluations, serum autoantibody testing, and digital subtraction angiography were negative. Subsequent diffusion-weighted brain magnetic resonance imaging demonstrated acute infarction in the right frontoparietal lobe. To find the etiology of this case, more detailed examinations were performed. Finally, she was diagnosed with ESUS, which was caused by the PAVF. CONCLUSIONS This case raises the awareness of a potential important emboligenic mechanism, the existence of an isolated PAVF as a right-to-left shunt in patients with a stroke of unknown origin should not be overlooked, even if a PAVF is not suggested by the initial physical findings or chest x-ray.

Abstract
BACKGROUND Patients who had a cryptogenic stroke (CS) suspected to be causally related to a patent foramen ovale (PFO) are candidates for percutaneous PFO closure. In such patients, it is important to screen for atrial fibrillation (AF). Limited guidance is available regarding AF monitoring strategies in CS patients with PFO addressing optimal monitoring technology and duration. AIM To provide a narrative review of cardiac rhythm monitoring in CS patients considered for PFO closure, including current practices, stroke recurrences after CS, findings from monitoring studies in CS patients, and predictors for AF detection published in the literature. To propose a personalized strategy for cardiac monitoring in CS patients, accounting for aspects predicting AF detection. SUMMARY OF REVIEW AF detection in CS patients is predicted by age, left atrial enlargement, prolonged PR interval, frequent premature atrial contractions, interatrial conduction block, diabetes, prior brain infarctions, leukoaraiosis, elevated B-type natriuretic peptide (BNP)/N-terminal pro B-type natriuretic peptide (NT-proBNP) levels, and a family history of AF, as well as composed scores (e.g. CHA2DS2-VASc, atrial fibrillation in embolic stroke of undetermined source (AF-ESUS)). The causal role of the PFO may be accounted for by the risk of paradoxical embolism (RoPE) score and/or the PFO-Associated Stroke Causal Likelihood (PASCAL) classification. CONCLUSION A personalized approach to AF detection in CS patients is proposed, accounting for the likelihood of AF detection and aimed at obtaining sufficient confidence regarding the absence of AF in patients considered for PFO closure. In addition, the impact of high-risk PFO features on the monitoring strategy is discussed.

Abstract
IntroductionLong-term cardiac monitoring studies have unveiled low-burden, occult atrial fibrillation (AF) in some patients with otherwise cryptogenic stroke (CS), but occult AF is also found in some individuals without a stroke history and in patients with stroke of a known cause (KS). Clinical management would be aided by estimates of how often occult AF in a patient with CS is causal vs. incidental.MethodsThrough a systematic search, we identified all case–control and cohort studies applying identical long-term monitoring techniques to both patients with CS and KS. We performed a random-effects meta-analysis across these studies to determine the best estimate of the differential frequency of occult AF in CS and KS among all patients and across age subgroups. We then applied Bayes' theorem to determine the probability that occult AF is causal or incidental.ResultsThe systematic search identified three case–control and cohort studies enrolling 560 patients (315 CS, 245 KS). Methods of long-term monitoring were implantable loop recorder in 31.0%, extended external monitoring in 67.9%, and both in 1.2%. Crude cumulative rates of AF detection were CS 47/315 (14.9%) vs. KS 23/246 (9.3%). In the formal meta-analysis, the summary odds ratio for occult AF in CS vs. KS in all patients was 1.80 (95% CI, 1.05–3.07), p = 0.03. With the application of Bayes' theorem, the corresponding probabilities indicated that, when present, occult AF in patients with CS is causal in 38.2% (95% CI, 0–63.6%) of patients. Analyses stratified by age suggested that detected occult AF in patients with CS was causal in 62.3% (95 CI, 0–87.1%) of patients under the age of 65 years and 28.5% (95 CI, 0–63.7%) of patients aged 65 years and older but estimates had limited precision.ConclusionCurrent evidence is preliminary, but it indicates that in cryptogenic stroke when occult AF is found, it is causal in about 38.2% of patients. These findings suggest that anticoagulation therapy may be beneficial to prevent recurrent stroke in a substantial proportion of patients with CS found to have occult AF.

Abstract
INTRODUCTION In patients with cryptogenic stroke, one of the most frequently found abnormalities is patent foramen ovale (PFO). Percutaneous 'deviceless' systems based on surgical suture-mediated PFO closure have recently been introduced and show a favorable efficacy and safety profile with clear advantages. OBJECTIVES To present procedural details of the technique and baseline characteristics of patients who underwent the procedure in our center. METHODS A single-center prospective observational registry was established between February 2020 and February 2021, to assess the safety, efficacy and possible advantages of a novel percutaneous PFO closure system (NobleStitch® EL). Patient and PFO characteristics as well as technical features were collected for analysis. RESULTS Twenty-three patients were considered suitable for this technique after transesophageal echocardiography. Their mean age was 51 years and 69.5% were women. Most patients (91.3%) had a history of cryptogenic stroke. PFO closure with the NobleStitch® system was successfully performed in all patients. All procedures were performed under local anesthesia and fluoroscopic monitoring. The mean duration of the procedure was 52 min and median contrast dose used was 187 ml. Median radiation dose absorbed per patient was 61.5 Gy cm2. All patients were discharged asymptomatic 24 hours after the procedure with no peri- or postprocedural complications recorded. CONCLUSION Suture-mediated PFO closure represents a valid and safe alternative to traditional umbrella-like devices, and is feasible in the majority of PFO anatomies. Follow-up information, results of larger series and clinical trials may possibly validate this technique as the first choice for PFO closure.

Abstract
INTRODUCTION There is an extending use of percutaneous closure of patent foramen ovale (PFO) as therapy for PFO-associated cryptogenic strokes. The aim of our study was to investigate the clinical practice of percutaneous closure of PFO and to analyse the variables for decision-making on the selection of patients for this procedure. METHOD A prospective observational multicentric survey was conducted using all the cases of cryptogenic stroke/transient ischaemic attack associated with PFO recorded in the NORDICTUS hospital registry during the period 2018-2021. Clinical data, radiological patterns, echocardiogram data and factors related to PFO-associated stroke (thromboembolic disease and paradoxical embolism criteria) were recorded. The indication for closure was analysed according to age (≤/> 60 years) and the characteristics of the PFO. RESULTS In the group ≤ 60 years (n = 488), 143 patients (29.3%) underwent PFO closure. The most influential variables for this therapy were detection of a high-risk PFO (OR 4.11; IC 2.6-6.5, P < .001), criteria for paradoxical embolism (OR 2.61; IC 1.28-5.28; P = .008) and previous use of antithrombotics (OR 2.67; IC 1.38-5.18; P = .009). In the > 60 years group (n = 124), 24 patients had PFO closure (19%). The variables related to this option were history of pulmonary thromboembolism, predisposition to thromboembolic disease, paradoxical embolism criteria, and high-risk PFO. CONCLUSIONS The detection of a high-risk PFO (large shunt, shunt with associated aneurysm) is the main criterion for a percutaneous closure-based therapy. Other conditions to consider in the eligibility of patients are the history of thromboembolic disease, paradoxical embolism criteria or the previous use of antithrombotics.

Front Public Health 2022; 10:1016854. [PMID: 36407985 PMCID: PMC9669480 DOI: 10.3389/fpubh.2022.1016854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Accepted: 09/13/2022] [Indexed: 11/06/2022] Open
Abstract
Background In 2019, there were 28. 76 million patients with stroke in China, with ~25% of them suffering from cryptogenic stroke (CS). Patent foramen ovale (PFO) is related to CS, and PFO closure can reduce recurrent stroke. To date, no study has investigated the cost-effectiveness of PFO closure vs. medical therapy among such populations in China. Methods A Markov model with a cycle length of 3 months was established to compare the 30-year cost-effectiveness of PFO closure and medical therapy. The transition probability of recurrent stroke was derived from the RESPECT study, and the costs and utility were obtained from domestic data or studies conducted in China. The primary outcome of this study was the incremental cost-effectiveness ratio (ICER), which represents the incremental cost per quality-adjusted life year (QALY). PFO closure was considered cost-effective if the ICER obtained was lower than the willingness-to-pay (WTP) threshold of 37,654 USD/QALY; otherwise, PFO closure was regarded as not being cost-effective. One-way and probabilistic sensitivity analyses were performed to test the robustness of the results. Results After a simulation of a 30-year horizon, a cryptogenic stroke patient with PFO was expected to have QALY of 13.15 (15.26 LY) if he received PFO closure and a corresponding value of 11.74 QALY (15.14 LY) after medical therapy. The corresponding costs in both cohorts are US $8,131 and US $4,186, respectively. Thus, an ICER of 2783 USD/QALY and 31264 USD/LY was obtained, which is lower than the WTP threshold. One-way and probabilistic sensitivity analyses showed that the results were robust. Conclusion With respect to the WTP threshold of three times per capita GDP in China in 2021, PFO closure is a cost-effective method for Chinese cryptogenic stroke patients with PFO, as shown in the 30-year simulation.

Abstract
A 61-year-old man presented with transient dysarthria and left upper extremity numbness. Head MRI showed an acute infarct in the left temporal lobe and multiple old infarcts in the bilateral cortices. A transesophageal echocardiogram revealed a patent foramen ovale with a large shunt. No deep vein thrombosis was found. He suffered a recurrent cerebral infarction while taking antiplatelet therapy. An insertable cardiac monitor was implanted on the 41st day, and the antiplatelet treatment was changed to warfarin. The insertable cardiac monitor did not detect atrial fibrillation, even when the patient had a recurrent transient ischemic attack on the 57th day under warfarin therapy. The patient underwent percutaneous foramen ovale closure on the 63rd day. On postoperative days 18-25, an insertable cardiac monitor detected brief atrial fibrillation, and he took rivaroxaban for three months. Atrial fibrillation may occur secondary to percutaneous patent foramen ovale closure for cryptogenic stroke. The insertable cardiac monitor may help diagnose the pathogenesis of secondary atrial fibrillation and determine the optimal antithrombotic therapy.

Abstract
Although a pathophysiological impact remains difficult to prove in individual patient care, a patent foramen ovale (PFO) is currently considered of high relevance for secondary prophylaxis in selected patients with cryptogenic ischemic stroke. By quantification of histological clot composition, we aimed to enhance pathophysiological understanding of PFO attributable ischemic strokes. Retrospectively, we evaluated all cerebral clots retrieved by mechanical thrombectomy for acute ischemic stroke treatment between 2011 and 2021 at our comprehensive stroke care center. Inclusion criteria applied were cryptogenic stroke, age (≤60 years), and PFO status according to transesophageal echocardiography, resulting in a study population of 58 patients. Relative clot composition was calculated using orbit image analysis to define the ratio of main histologic components (fibrin/platelets (F/P), red blood cell count (RBC), leukocytes). Cryptogenic stroke patients with PFO (PFO+, n = 20) displayed a significantly higher percentage of RBC (0.57 ± 0.17; p = 0.002) and lower percentage of F/P (0.38 ± 0.15; p = 0.003) compared to patients without PFO (PFO–, n = 38) (RBC: 0.41 ± 0.21; F/P: 0.52 ± 0.20). In conclusion, histologic clot composition in cryptogenic stroke varies depending on the presence of a PFO. Our findings histologically support the concept that a PFO may be of pathophysiological relevance in cryptogenic ischemic stroke.

Abstract
Patent foramen ovale (PFO) describes a valve in the interatrial septum that permits shunting of blood or thrombotic material between the atria. PFOs are present in approximately 25% of the healthy population and are not associated with any pathology in the vast majority of cases. However, comparisons between patients with stroke and healthy controls suggest that PFOs may be causative of stroke in certain patients whose stroke is otherwise cryptogenic. Options for the diagnosis of PFO include transthoracic echocardiography, transesophageal echocardiography, and transcranial Doppler ultrasonography. PFOs associated with an interatrial septal aneurysm seem to be more strongly linked to risk of recurrent stroke. Therapeutic options for secondary stroke prevention in the setting of a PFO include antiplatelet therapy, anticoagulation, and percutaneous device closure. Recent randomized clinical trials suggest that percutaneous closure reduces the subsequent risk of stroke in appropriately selected patients, with a large relative benefit but small absolute benefit. Referral for percutaneous PFO closure should therefore be considered in certain patients after a multidisciplinary, patient centered discussion. Areas for future study include structural biomarkers to aid in determining the role of PFO closure in older people with possible PFO associated stroke, the role of direct oral anticoagulants, and very long term outcomes after device closure.

Abstract
OBJECTIVES Transcranial Doppler ultrasound (TCD) is noninvasive and highly sensitive and specific for the diagnosis of patent foramen ovale (PFO). We evaluated the diagnostic implications of the TCD with a saline agitation test as a routine work-up for ischemic stroke patients. METHODS A TCD bubble study was performed in all consecutive ischemic stroke patients as a routine work-up. We evaluated the prevalence of microembolic signals (MES) for each stroke etiology and the optimal number of MES for predicting the PFO-attributable stroke. RESULTS Subjects (N = 499) with acute ischemic stroke were enrolled. A significant fraction of patients had MES during both normal respiration (5.7-44.4%) and the Valsalva maneuver (19.5-55.6%) across all stroke etiology categories. The optimal MES threshold for the diagnosis of PFO-attributable stroke confirmed by transesophageal echocardiography was 46 MES during the Valsalva maneuver (96% sensitivity and 95% specificity). Applying ≥46 MES during the Valsalva maneuver as a threshold effectively increased the ability to differentially diagnose PFO-attributable stroke from other etiologies. The number of MES during the Valsalva maneuver was negatively correlated with increasing age (r = -.108; P = .016). CONCLUSIONS A significant fraction of patients had right to left shunt across all Trial of ORG 10172 in Acute Stroke Treatment etiologies. A threshold number of MES facilitated the differential diagnosis of PFO-attributable stroke from other etiologies, and the optimal threshold was 46 MES during the Valsalva maneuver.

Abstract
Intracardiac microbubbles may occur inadvertently during a cardiac procedure, which are typically reported in patients with central venous catheters or cardiac prosthetic valves. Here, we report a case wherein a microbubble filling in the bilateral atriums and ventricles was revealed during echocardiography despite the patient not having the aforementioned risks. An 87-year-old man with hypertension was admitted with a diagnosis of heart failure caused by a giant hiatal hernia. While awaiting hernia surgery, he started vomiting and suddenly went into a coma. A contrast-enhanced computed tomography (CT) scan of the abdomen showed a thickening of the gastric wall, intramural gas, and portal vein gas. Considering these findings, a giant esophageal hiatus hernia was suspected as the cause of the intracardiac microbubbles. In addition, an echocardiogram showed a patent foramen ovale, and the magnetic resonance imaging (MRI) of the head showed multiple cerebral infarctions bilaterally in the cerebral hemispheres. Therefore, a paradoxical air embolism was suspected to cause the coma in this patient. A giant esophageal hiatus hernia can cause portal vein gas triggered by an increased intragastric pressure (which causes vomiting). Then, the portal vein gas flows into the right heart via the sinusoids. Cerebral air embolism can also develop via a shunt, such as a patent foramen ovale, and trigger a foreign body reaction via inflammation and cause coma. When microbubbles are observed in the heart on an echocardiogram, it is necessary to seek the place of entry because it can be a lethal sign due to complications that could follow, such as a cerebral air embolism or pulmonary air embolism.

Abstract
BACKGROUND The best antithrombotic strategy for cryptogenic stroke with potential cardiac emboli is not known. The objective of this study was to conduct a meta-analysis to evaluate the efficacy and safety of oral anticoagulants (OACs) vs. antiplatelet therapies in these patients METHODS: Pubmed, EMBASE, CENTRAL and clinicaltrials.gov were searched from January 1980 to April 2021 to identify trials comparing OACs versus antiplatelet therapies in patients with cryptogenic stroke and potential cardiac emboli (patent foramen ovale, moderate-severe left atrial enlargement, heart failure with reduced ejection fraction). Relative risk (RR) with 95% confidence (CI) was used as a measure of the effect of OACs versus antiplatelet therapies on recurrent ischemic stroke and major bleeding. We computed a random-effect estimate based on the Mantel-Haenszel method for a given outcome. RESULTS We identified 6 studies derived from 5 trials with 2282 patients. Pooled results from 6 studies showed that compared with antiplatelet therapies, OACs were associated with a lower risk of recurrent ischemic stroke (RR 0.61, 95% CI 0.41 to 0.91, P=0.02). Only 3 studies of cryptogenic stroke with patent foramen ovale reported a major bleeding endpoint and pooled results from random-effects model showed that OACs compared with antiplatelet therapies were associated with a non-significantly increased risk of major bleeding (RR 1.61, 95% CI 0.76 to 3.40, P=0.21). CONCLUSIONS OACs compared with antiplatelet therapies were associated with a reduced recurrent ischemic stroke risk and OACs might be a viable non-procedural alternative in patients with cryptogenic stroke and potential cardiac emboli.

Abstract
The management of patients with stroke is often multidisciplinary, involving various specialties and healthcare professionals. Given the common shared risk factors for stroke and cardiovascular disease, input may also be required from the cardiovascular teams, as well as patient caregivers and next-of-kin. Ultimately, the patient is central to all this, requiring a coordinated and uniform approach to the priorities of post-stroke management, which can be consistently implemented by different multidisciplinary healthcare professionals, as part of the patient ‘journey’ or ‘patient pathway,’ supported by appropriate education and tele-medicine approaches. All these aspects would ultimately aid delivery of care and improve patient (and caregiver) engagement and empowerment. Given the need to address the multidisciplinary approach to holistic or integrated care of patients with heart disease and stroke, the European Society of Cardiology Council on Stroke convened a Task Force, with the remit to propose a consensus on Integrated care management for optimizing the management of stroke and associated heart disease. The present position paper summarizes the available evidence and proposes consensus statements that may help to define evidence gaps and simple practical approaches to assist in everyday clinical practice. A post-stroke ABC pathway is proposed, as a more holistic approach to integrated stroke care, would include three pillars of management:
A: Appropriate Antithrombotic therapy. B: Better functional and psychological status. C: Cardiovascular risk factors and Comorbidity optimization (including lifestyle changes).

Abstract
BACKGROUND Stroke is a problem worldwide because of its high mortality and disability rates. Almost 90% of strokes are ischemic, and more than half of the deaths are caused by an ischemic stroke. Most risk factors for stroke are manageable so that it can be avoided with proper prevention. Despite the success in determining the causes of stroke in recent years, selectively, the "culprit" causing stroke remains unsolved. In such cases, a diagnosis of undetermined etiology (cryptogenic stroke) or embolic stroke of undetermined source (ESUS) is generated, resulting the prevention of a recurrent cerebrovascular occurrence impossible. Atrial fibrillation (AF) can be a cause of stroke by causing blood clots in the chambers of the heart. PURPOSE The aim was to determine the optimal method of heart rate monitoring in patients with ischemic stroke, as methods and approaches for detecting AF are very diverse, but there is still no single opinion, which would be universal. PROCEDURES In our review, we consider epidemiology, risk factors for the stroke of undetermined etiology, as well as analytical methods for detecting heart rhythm disturbances in this category of patients. FINDINGS Atrial fibrillation (AF) is detected by thorough monitoring of heart rate of patients with cryptogenic stroke and ESUS can be diagnosed in up to 46% of patients. . CONCLUSION After AF detection, consideration should be given to prescribing anticoagulants, instead of antiplatelet agents, for the secondary prevention of stroke.

Abstract
Importance Patent foramen ovale (PFO)-associated strokes comprise approximately 10% of ischemic strokes in adults aged 18 to 60 years. While device closure decreases stroke recurrence risk overall, the best treatment for any individual is often unclear. Objective To evaluate heterogeneity of treatment effect of PFO closure on stroke recurrence based on previously developed scoring systems. Design, Setting, and Participants Investigators for the Systematic, Collaborative, PFO Closure Evaluation (SCOPE) Consortium pooled individual patient data from all 6 randomized clinical trials that compared PFO closure plus medical therapy vs medical therapy alone in patients with PFO-associated stroke, and included a total of 3740 participants. The trials were conducted worldwide from 2000 to 2017. Exposures PFO closure plus medical therapy vs medical therapy alone. Subgroup analyses used the Risk of Paradoxical Embolism (RoPE) Score (a 10-point scoring system in which higher scores reflect younger age and the absence of vascular risk factors) and the PFO-Associated Stroke Causal Likelihood (PASCAL) Classification System, which combines the RoPE Score with high-risk PFO features (either an atrial septal aneurysm or a large-sized shunt) to classify patients into 3 categories of causal relatedness: unlikely, possible, and probable. Main Outcomes and Measures Ischemic stroke. Results Over a median follow-up of 57 months (IQR, 24-64), 121 outcomes occurred in 3740 patients. The annualized incidence of stroke with medical therapy was 1.09% (95% CI, 0.88%-1.36%) and with device closure was 0.47% (95% CI, 0.35%-0.65%) (adjusted hazard ratio [HR], 0.41 [95% CI, 0.28-0.60]). The subgroup analyses showed statistically significant interaction effects. Patients with low vs high RoPE Score had HRs of 0.61 (95% CI, 0.37-1.00) and 0.21 (95% CI, 0.11-0.42), respectively (P for interaction = .02). Patients classified as unlikely, possible, and probable using the PASCAL Classification System had HRs of 1.14 (95% CI, 0.53-2.46), 0.38 (95% CI, 0.22-0.65), and 0.10 (95% CI, 0.03-0.35), respectively (P for interaction = .003). The 2-year absolute risk reduction was -0.7% (95% CI, -4.0% to 2.6%), 2.1% (95% CI, 0.6%-3.6%), and 2.1% (95% CI, 0.9%-3.4%) in the unlikely, possible, and probable PASCAL categories, respectively. Device-associated adverse events were generally higher among patients classified as unlikely; the absolute risk increases in atrial fibrillation beyond day 45 after randomization with a device were 4.41% (95% CI, 1.02% to 7.80%), 1.53% (95% CI, 0.33% to 2.72%), and 0.65% (95% CI, -0.41% to 1.71%) in the unlikely, possible, and probable PASCAL categories, respectively. Conclusions and Relevance Among patients aged 18 to 60 years with PFO-associated stroke, risk reduction for recurrent stroke with device closure varied across groups classified by their probabilities that the stroke was causally related to the PFO. Application of this classification system has the potential to guide individualized decision-making.

Abstract
Multiple randomized clinical trials have demonstrated the benefit of patent foramen ovale closure over medical therapy alone for patients who have had a stroke that has been attributed to the patent foramen ovale. Nevertheless, there are many areas of uncertainty and controversy related to patient selection, pathophysiology, diagnosis, and treatment. We summarize the available data on these challenging topics and attempt to provide some clarity and future directions for clinicians and investigators.

Patent Foramen Ovale Channel Morphometric Characteristics Associated with Cryptogenic Stroke: The MorPFO Score. J Am Soc Echocardiogr 2021; 34:1285-1293.e3.

Abstract
BACKGROUND It is still disputable whether the specific morphologic properties of patent foramen ovale (PFO) may contribute to the occurrence of stroke. The aim of this study was to evaluate the differences in the morphometric and functional features of the PFO channel in patients with cryptogenic stroke and those without stroke. METHODS PFO channel morphology in 106 consecutive patients with cryptogenic stroke and 93 control patients without stroke with diagnosed PFO (by transesophageal echocardiography) was analyzed using transesophageal echocardiography. A validation cohort was established that consisted of 31 patients with cryptogenic stroke and 30 without stroke. RESULTS Multivariable regression logistic analyses indicated PFO channel length change (odds ratio [OR], 2.50; 95% confidence interval [CI], 1.75-3.55; P < .001), PFO length/height ratio during the Valsalva maneuver (OR, 0.75; 95% CI, 0.60-0.95; P = .015), septum primum thickness (OR, 0.34; 95% CI, 0.14-0.80; P = .013), septum secundum height (OR, 0.91; 95% CI, 0.84-0.98; P = .013), the presence of an atrial septal aneurysm (OR, 3.38; 95% CI, 1.27-8.97; P = .014), and large shunt (OR, 2.49; 95% CI, 1.13-5.46; P = .022) as PFO-related stroke factors. The Morphologic Stroke Factors of PFO (MorPFO) score was developed, in which six factors were included: PFO channel length reduction (≥21%; 7 points), short septum secundum (<8.6 mm; 5 points), thin septum primum (<1.6 mm; 3 points), large right-to-left shunt (3 points), low PFO channel length/height ratio during the Valsalva maneuver (≤2.1; 2 points), and atrial septal aneurysm presence (1 point). Patients with scores of 0 to 7 points have low-risk PFO channels, those with scores of 8 to 11 points have intermediate-risk PFO channels, and those with scores of 12 to 21 points have high-risk PFO channels. External validation showed good MorPFO score performance (C index = 0.90). CONCLUSIONS Transesophageal echocardiography can be used to differentiate pathogenic from incidental PFO channels on the basis of their morphologic characteristics. The MorPFO score may help identify high-stroke-risk PFO channels.

Patent Foramen Ovale Attributable Cryptogenic Embolism With Thrombophilia Has Higher Risk for Recurrence and Responds to Closure. JACC Cardiovasc Interv 2021; 13:2745-2752. [PMID: 33303111 DOI: 10.1016/j.jcin.2020.09.059] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 07/22/2020] [Accepted: 09/15/2020] [Indexed: 01/22/2023]
Abstract
OBJECTIVES The aim of this study was to investigate the effect of management on the risk for recurrent events among patients with cryptogenic ischemic stroke or transient ischemic attack. BACKGROUND The combination of patent foramen ovale (PFO) and hypercoagulability may greatly increase the risk for paradoxical embolism. However, previous randomized controlled trials evaluating the efficacy of PFO closure excluded these potential high-risk patients. METHODS Patients diagnosed with PFO attributable cryptogenic embolism were prospectively, without randomization, recruited from January 2005 to March 2018. The relationship between thrombophilia and recurrent events was evaluated in overall patients. Multivariate Cox regression was conducted to assess the relative risk for recurrence in PFO closure and medical therapy groups. RESULTS A total of 591 patients with cryptogenic embolism with PFO were identified. The median duration of follow-up was 53 months, and thrombophilia significantly increased the risk for recurrent events (hazard ratio [HR]: 1.85; 95% confidence interval [CI]: 1.09 to 3.16; p = 0.024). PFO closure was superior to medical therapy in overall patients (HR: 0.16; 95% CI: 0.09 to 0.30; p < 0.001). Of the 134 patients (22.7%) with thrombophilia, there was a difference in the risk for recurrence events between the PFO closure (6 of 89) and medical therapy (15 of 45) groups (HR: 0.25; 95% CI: 0.08 to 0.74; p = 0.012). There was no potential heterogeneity in the further subgroup analysis. CONCLUSIONS Patients with cryptogenic stroke with PFO and hypercoagulable state had increased risk for recurrent stroke or transient ischemic attack. PFO closure provided a lower risk for recurrent events compared with medical therapy alone.

Abstract
The 2020 update of the Canadian Stroke Best Practice Recommendations (CSBPR) for the Secondary Prevention of Stroke includes current evidence-based recommendations and expert opinions intended for use by clinicians across a broad range of settings. They provide guidance for the prevention of ischemic stroke recurrence through the identification and management of modifiable vascular risk factors. Recommendations address triage, diagnostic testing, lifestyle behaviors, vaping, hypertension, hyperlipidemia, diabetes, atrial fibrillation, other cardiac conditions, antiplatelet and anticoagulant therapies, and carotid and vertebral artery disease. This update of the previous 2017 guideline contains several new or revised recommendations. Recommendations regarding triage and initial assessment of acute transient ischemic attack (TIA) and minor stroke have been simplified, and selected aspects of the etiological stroke workup are revised. Updated treatment recommendations based on new evidence have been made for dual antiplatelet therapy for TIA and minor stroke; anticoagulant therapy for atrial fibrillation; embolic strokes of undetermined source; low-density lipoprotein lowering; hypertriglyceridemia; diabetes treatment; and patent foramen ovale management. A new section has been added to provide practical guidance regarding temporary interruption of antithrombotic therapy for surgical procedures. Cancer-associated ischemic stroke is addressed. A section on virtual care delivery of secondary stroke prevention services in included to highlight a shifting paradigm of care delivery made more urgent by the global pandemic. In addition, where appropriate, sex differences as they pertain to treatments have been addressed. The CSBPR include supporting materials such as implementation resources to facilitate the adoption of evidence into practice and performance measures to enable monitoring of uptake and effectiveness of recommendations.

Abstract
Prevention of ischemic stroke relies on the use of antithrombotic medications comprising antiplatelet agents and anticoagulation. Stroke risk is particularly high in patients with cardiovascular disease. This review will focus on the role of antithrombotic therapies in the context of different types of cardiovascular disease. We will discuss oral antiplatelet medications and both IV and parental anticoagulants. Different kinds of cardiovascular disease contribute to stroke via distinct pathophysiological mechanisms, and the optimal treatment for each varies accordingly. We will explore the mechanism of stroke and evidence for antithrombotic therapy in the following conditions: atrial fibrillation, prosthetic heart values (mechanical and bioprosthetic), aortic arch atherosclerosis, congestive heart failure (CHF), endocarditis (infective and nonbacterial thrombotic endocarditis), patent foramen ovale (PFO), left ventricular assist devices (LVAD), and extracorporeal membrane oxygenation (ECMO). While robust data exist for antithrombotic use in conditions such as atrial fibrillation, optimal treatment in many situations remains under active investigation.

Abstract
Background Results of randomized controlled trials (RCT) do not provide definite guidance for secondary prevention after ischemic stroke (IS)/transient ischemic attack (TIA) attributed to patent foramen ovale (PFO). No recommendations can be made for patients > 60 years. We aimed to compare interventional and medical PFO-management in cryptogenic IS/TIA patients, including patients > 60 years. Methods Prospective case series including consecutive cryptogenic IS/TIA patients with PFO at Tuebingen university stroke unit, Germany. ‘PFO-closure’ was recommended in patients ≤70 years when featuring high-risk PFO (i.e., with atrial septal aneurysm, spontaneous, or high-grade right-to-left shunt during Valsalva). Primary (recurrent IS/intracranial hemorrhage) and secondary endpoints (e.g., disability) were assessed during ≥1-year follow-up; planned subgroup analyses of patients ≤60/> 60 years. Results Among 236 patients with median age of 58 (range 18–88) years, 38.6% were females and median presenting National Institutes of Health Stroke Scale score was 1 (IQR 0–4). Mean follow-up was 2.8 ± 1.3 years. No intracranial hemorrhage was observed. Recurrent IS rate after ‘PFO-closure’ was 2.9% (95%CI 0–6.8%) and 7% (4–16.4) in high-risk PFO patients ≤60 (n = 103) and > 60 years (n = 43), respectively, versus 4% (0–11.5) during ‘medical therapy alone’ MTA (n = 28). 42 low-risk PFO patients treated with MTA experienced no recurrent IS/TIA. Conclusions In our real-world study, IS recurrence rate in ‘PFO-closure’ high-risk PFO patients ≤60 years was comparable to that observed in recent RCT. High-risk PFO patients > 60 years who underwent PFO-closure had similar IS recurrence rates than those who received MTA. MTA seems the appropriate treatment for low-risk PFO.

Abstract
Patients with neurologic disease are at high risk of venous thromboembolism (VTE). The converse risk of neurological complications in concert or following peripheral VTE is rarely considered. The major neurologic complication following pulmonary embolism or peripheral VTE is intracranial hemorrhage that occurs following anticoagulation therapy for VTE. Ischemic stroke may occur concomitantly with VTE. VT occurrence may also be a marker for a future increased risk of stroke. Peripheral neuropathy may occur or neuropathic pain may occur as a result of thrombophlebitis following deep venous thrombosis. Other sequelae of VTE are somewhat theoretical including the discovery of central nervous system malignancies after incident VTE.

Abstract
Importance Recent epidemiologic and therapeutic advances have transformed understanding of the role of and therapeutic approach to patent foramen ovale (PFO) in ischemic stroke. Patent foramen ovale is likely responsible for approximately 5% of all ischemic strokes and 10% of those occurring in young and middle-aged adults. Observations Randomized clinical trials have demonstrated that, to prevent recurrent ischemic stroke in patients with PFO and an otherwise-cryptogenic index ischemic stroke, PFO closure is superior to antiplatelet medical therapy alone; these trials have provided some evidence that, among medical therapy options, anticoagulants may be more effective than antiplatelet agents. Conclusions and Relevance These new data indicate a need to update classification schemes of causative mechanisms in stroke, developed in an era in which an association between PFO and stroke was viewed as uncertain. We propose a revised general nomenclature and classification framework for PFO-associated stroke and detailed revisions for the 3 major stroke subtyping algorithms in wide use.

Abstract
Background: The risk of paradoxical embolism (RoPE) score calculates the probability that
patent foramen ovale (PFO) is causally related to stroke (PFO attributable
fraction, PFOAF), based on PFO prevalence in patients with cryptogenic
stroke (CS) compared with that in the general population. The latter has
been estimated at 25%; however, PFO prevalence in nonselected populations
varies widely. Methods: Since PFO prevalence in Greece remains unknown, we evaluated it and we
calculated PFOAF stratified by RoPE score in a cohort of patients with
CS ⩽55 years old. PFO was detected according to the international consensus
transcranial Doppler (TCD) criteria in 124 healthy subjects (H), in 102
patients with CS, and in 56 patients with stroke of known cause (nonCS).
Each subject underwent unilateral middle cerebral artery recording after
infusion of agitated saline, at rest, and after a controlled Valsalva
maneuver. We characterized PFO as large (>20 microbubbles or curtain),
moderate (11–20), and small (⩽10). Results: PFO was detected in 42.7% of H, 49% of CS, and 25% of nonCS
(p = 0.013). Large PFOs were numerically higher in CS
[28.4% (29/102)] compared with H [19.3% (24/124); p = 0.1]
and to nonCS [7.1% (4/56), p = 0.04]. The median RoPE score
in patients with CS and PFO was seven. Even patients with very high RoPE
score (9–10) had moderate PFOAF (57%). For any individual stratum up to RopE
score 8, PFOAF was <33%. Conclusions: PFO prevalence in the Greek population is much higher than the widely
accepted 25%. PFO may be the cause of stroke in one out of nine Greek
patients with CS. Among Greek CS patients who harbor a PFO, the latter is
causal in one out of five. The established RoPE score cutoff of ⩾7 for
having a probable PFO-associated stroke may overestimate the probability in
patients deriving from populations with high PFO prevalence.

Abstract
Few randomized controlled trials have evaluated the effectiveness of continuous positive airway pressure (CPAP) in reducing recurrent vascular events and mortality in poststroke obstructive sleep apnea (OSA). To date, results have been mixed, most studies were underpowered and definitive conclusions are not available. Using lessons learned from prior negative trials in stroke, we reappraise prior randomized controlled trials that examined the use of CPAP in treating poststroke OSA and propose the following considerations: (1) Intervention-based changes, such as ensuring that patients are using CPAP for at least 4 hours per night (eg, through use of improvements in CPAP technology that make it easier for patients to use), as well as considering alternative treatment strategies for poststroke OSA; (2) Population-based changes (ie, including stroke patients with severe and symptomatic OSA and CPAP noncompliers); and (3) Changes to timing of intervention and follow-up (ie, early initiation of CPAP therapy within the first 48 hours of stroke and long-term follow-up calculated in accordance with sample size to ensure adequate power). Given the burden of vascular morbidity and mortality in stroke patients with OSA, there is a strong need to learn from past negative trials and explore innovative stroke prevention strategies to improve stroke-free survival.

Abstract
Background and purpose Ischemic stroke is a widespread disease carrying high morbidity and mortality. Transesophageal echocardiography (TEE) is considered an important tool in the work-up of patients with acute ischemic stroke (AIS) and transient ischemic attack (TIA) patients; its utility is limited by a semi-invasive nature. The purpose of this study was to evaluate the probability of treatment change due to TEE findings (yield) in the work-up of AIS and TIA patients. Methods Retrospective data on patients with AIS or TIA who underwent TEE examination between 2000–2013 were collected from the institutional registry. Results The average age of 1284 patients who were included in the study was 57±10.4, 66% of patients were male. The most frequent TEE findings included aortic plaques in 54% and patent foramen ovale (PFO) in 15%. TEE findings led to treatment change in 135 (10.5%) patients; anticoagulant treatment was initiated in 110 of them (81%). Most common etiology for switch to anticoagulation was aortic plaques (71 patients); PFO was second most common reason (26 patients). Significant TEE findings (thrombus, endocarditis, tumor) were found in 1.9% of patients, they were more common in young patients (<55; 56% of the patients). Conclusions The beginning of anticoagulation treatment in patients with thick and complicated plaques was found frequently in our study. Significant TEE findings, were infrequent, constituted an absolute indication for treatment change and were more common in younger patients.

Abstract
BACKGROUND AND PURPOSE In patients with cryptogenic stroke and patent foramen ovale (PFO), the Risk of Paradoxical Embolism (RoPE) Score has been proposed as a method to estimate a patient-specific "PFO-attributable fraction"-the probability that a documented PFO is causally-related to the stroke, rather than an incidental finding. The objective of this research is to examine the relationship between this RoPE-estimated PFO-attributable fraction and the effect of closure in 3 randomized trials. METHODS We pooled data from the CLOSURE-I (Evaluation of the STARFlex Septal Closure System in Patients With a Stroke and/or Transient Ischemic Attack due to Presumed Paradoxical Embolism through a Patent Foramen Ovale), RESPECT (Randomized Evaluation of Recurrent Stroke Comparing PFO Closure to Established Current Standard of Care Treatment), and PC (Clinical Trial Comparing Percutaneous Closure of Patent Foramen Ovale [PFO] Using the Amplatzer PFO Occluder With Medical Treatment in Patients With Cryptogenic Embolism) trials. We examine the treatment effect of closure in high RoPE score (≥7) versus low RoPE score (<7) patients. We also estimated the relative risk reduction associated with PFO closure across each level of the RoPE score using Cox proportional hazard analysis. We estimated a patient-specific attributable fraction using a PC trial-compatible (9-point) RoPE equation (omitting the neuroradiology variable), as well as a 2-trial analysis using the original (10-point) RoPE equation. We examined the Pearson correlation between the estimated attributable fraction and the relative risk reduction across RoPE strata. RESULTS In the low RoPE score group (<7, n=912), the rate of recurrent strokes per 100 person-years was 1.37 in the device arm versus 1.68 in the medical arm (hazard ratio, 0.82 [0.42-1.59] P=0.56) compared with 0.30 versus 1.03 (hazard ratio, 0.31 [0.11-0.85] P=0.02) in the high RoPE score group (≥7, n=1221); treatment-by-RoPE score group interaction, P=0.12. The RoPE score estimated attributable fraction anticipated the relative risk reduction across all levels of the RoPE score, in both the 3-trial (r=0.95, P<0.001) and 2-trial (r=0.92, P<0.001) analyses. CONCLUSIONS The RoPE score estimated attributable fraction is highly correlated to the relative risk reduction of device versus medical therapy. This observation suggests the RoPE score identifies patients with cryptogenic stroke who are likely to have a PFO that is pathogenic rather than incidental.

Abstract
Patent foramen ovale (PFO) is a common cardiac anatomic variant that has been increasingly found in young (<60 years) cryptogenic stroke patients. Despite initial neutral randomized-controlled clinical trials (RCTs), there have been four recent RCTs providing consistent data in favor of the efficacy and safety of PFO closure compared to medical therapy for secondary stroke prevention. However, taking into consideration the high prevalence of PFO, the low risk of stroke recurrence under medical treatment and the uncommon yet severe adverse events of the intervention, patient selection is crucial for attaining meaningful clinical benefits. Thorough workup to exclude alternative causes of stroke and identification of high-risk PFOs through clinical, neuroimaging and echocardiographic criteria are essential. Cost effectiveness of the procedure cannot be proven for the time being, since there are no robust data on clinical outcome after PFO-associated stroke but only limited anecdotal data suggesting low risk for long-term disability.

Abstract
BACKGROUND Unlike previous randomized clinical trials (RCTs), recent trials and meta-analyses have shown that transcatheter closure of patent foramen ovale (PFO) reduces stroke recurrence risk in young and middle-aged adults with an otherwise unexplained PFO-associated ischaemic stroke. AIM To produce an expert consensus on the role of transcatheter PFO closure and antithrombotic drugs for secondary stroke prevention in patients with PFO-associated ischaemic stroke. METHODS Five neurologists and five cardiologists with extensive experience in the relevant field were nominated by the French Neurovascular Society and the French Society of Cardiology to make recommendations based on evidence from RCTs and meta-analyses. RESULTS The experts recommend that any decision concerning treatment of patients with PFO-associated ischaemic stroke should be taken after neurological and cardiological evaluation, bringing together the necessary neurovascular, echocardiography and interventional cardiology expertise. Transcatheter PFO closure is recommended in patients fulfilling all the following criteria: age 16-60 years; recent (≤6 months) ischaemic stroke; PFO associated with atrial septal aneurysm (>10mm) or with a right-to-left shunt>20 microbubbles or with a diameter≥2mm; PFO felt to be the most likely cause of stroke after thorough aetiological evaluation by a stroke specialist. Long-term oral anticoagulation may be considered in the event of contraindication to or patient refusal of PFO closure, in the absence of a high bleeding risk. After PFO closure, dual anti-platelet therapy with aspirin (75mg/day) and clopidogrel (75mg/day) is recommended for 3 months, followed by monotherapy with aspirin or clopidogrel for≥5 years. CONCLUSIONS Although a big step forward that will benefit many patients has been taken with recent trials, many questions remain unanswered. Pending results from further studies, decision-making regarding management of patients with PFO-associated ischaemic stroke should be based on a close coordination between neurologists/stroke specialists and cardiologists.
