Abstract
Patent foramen ovale (PFO) is frequently identified in young patients with cryptogenic ischaemic stroke. Potential stroke mechanisms include paradoxical embolism from a venous clot which traverses the PFO, in situ clot formation within the PFO, and atrial arrhythmias due to electrical signalling disruption. The purpose of this guideline is to provide recommendations for diagnosing, treating, and long-term managing patients with ischaemic stroke and PFO. Conversely, Transient Ischaemic Attack (TIA) was not considered an index event in this context because only one RCT involved TIA patients. However, this subgroup analysis showed no significant differences between TIA and stroke outcomes. The working group identified questions and outcomes, graded evidence, and developed recommendations following the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach and the European Stroke Organisation (ESO) standard operating procedure for guideline development. This document underwent peer-review by independent experts and members of the ESO Guideline Board and Executive Committee. The working group acknowledges the current evidentiary gap in delineating an unequivocal diagnostic algorithm for the detection of PFO. Although transoesophageal echocardiography is conventionally held as the most accurate diagnostic tool for PFO identification, its status as the 'gold standard' remains unsubstantiated by rigorously validated evidence. We found high-quality evidence to recommend PFO closure plus antiplatelet therapy in selected patients aged 18-60 years in whom no other evident cause of stroke is found but a PFO (i.e. PFO-associated stroke). The PASCAL classification system can be used to select such candidates for PFO closure. Patients with both a large right-to-left shunt and an atrial septal aneurysm benefit most from PFO closure. There is insufficient evidence to make an evidence-based recommendation on PFO closure in patients older than 60 and younger than 18 years. We found low quality evidence to suggest against PFO closure in patients with unlikely PFO-related stroke according to the PASCAL classification, except in specific scenarios (Expert Consensus). We suggest against long-term anticoagulation in patients with PFO-associated stroke unless anticoagulation is indicated for other medical reasons. Regarding the long-term AF monitoring after PFO closure, the working group concluded that there remains significant uncertainty regarding the risks and benefits associated with the use of long-term cardiac monitoring, such as implantable loop recorders. This document provides additional guidance, in the form of evidence-based recommendations or expert consensus statements, on diagnostic methods for PFO detection, and medical management after PFO closure.

Clin Cardiol 2024; 47:e24251. [PMID: 38445759 PMCID: PMC10915992 DOI: 10.1002/clc.24251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Revised: 02/15/2024] [Accepted: 02/21/2024] [Indexed: 03/07/2024] Open
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 Scarce data exist on sex differences in patients with cryptogenic cerebrovascular events undergoing patent foramen ovale (PFO) closure. This study aimed to determine the sex differences in clinical profile, procedural characteristics, and long-term outcomes of patients with cryptogenic cerebrovascular events undergoing PFO closure. Methods and Results A retrospective cohort was used, including 1076 consecutive patients undergoing PFO closure because of a cryptogenic cerebrovascular event. Patients were divided into 2 groups: 469 (43.6%) women and 607 (56.4%) men. The median follow-up was 3 years (interquartile range, 2-8 years). Women were younger (46±13 versus 50±12 years; P<0.01) and had a higher risk of paradoxical embolism score (6.9±1.7 versus 6.6±1.6; P<0.01). Procedural characteristics and postprocedural antithrombotic therapy were similar. At follow-up, there were no differences in atrial fibrillation (women versus men: 0.47 versus 0.97 per 100 patient-years; incidence rate ratio [IRR], 0.55 [95% CI, 0.27-1.11]; P=0.095; adjusted P=0.901), stroke (0.17 versus 0.07 per 100 patient-years; IRR, 2.58 [95% CI, 0.47-14.1]; P=0.274; adjusted P=0.201), or transient ischemic attack (0.43 versus 0.18 per 100 patient-years; IRR, 2.58 [95% CI, 0.88-7.54]; P=0.084; adjusted P=0.121); nevertheless, women exhibited a higher incidence of combined ischemic cerebrovascular events (0.61 versus 0.26 per 100 patient-years; IRR, 2.58 [95% CI, 1.04-6.39]; P=0.041; adjusted P=0.028) and bleeding events (1.04 versus 0.45 per 100 patient-years; IRR, 2.82 [95% CI, 1.41-5.65]; P=0.003; adjusted P=0.004). Conclusions Compared with men, women with cryptogenic cerebrovascular events undergoing PFO closure were younger and had a higher risk of paradoxical embolism score. After a median follow-up of 3 years, there were no differences in stroke events, but women exhibited a higher rate of combined (stroke and transient ischemic attack) cerebrovascular events and bleeding complications. Additional studies are warranted to clarify sex-related outcomes after PFO closure further.

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
The incidence of stroke in young individuals has been showing an increasing trend. In such cases, atypical mechanisms of stroke should be considered. Here, we report a case of a 37-year-old healthy female who presented with complaints of right-sided ataxia and clumsiness that started after an amusement park ride where she was swung rapidly. Imaging revealed an infarct in the right cerebellar hemisphere. This case report highlights certain mechanisms that can cause a stroke in this situation, with special emphasis on recognition, timely medical management, public awareness of such risk factors, and the prevention of complications.

Abstract
In 2014, Hart et al. introduced the concept of "embolic stroke of undetermined source" (ESUS) to the clinical-research stroke community. The hypothesis underlying the development of the ESUS construct was that this potentially heterogenous group of stroke mechanisms were largely thromboembolic, and would thus benefit from anticoagulation over antiplatelet for secondary prevention. Since then, 2 large clinical trials have shown that, to date, there is not a clear uniform antithrombotic strategy for secondary prevention after ESUS as it was originally broadly defined. However, this work has yielded valuable information about the patient phenotypes that experience ESUS strokes, as well as hypothesis-generating substudies that have given rise to the next generation of secondary prevention trials aimed at more personalized approaches for different suspected mechanisms of embolic stroke. In parallel with the evolution of ESUS, several studies aimed at screening for atrial fibrillation in the secondary stroke prevention population have generated additional questions about the mechanistic relevance of atrial fibrillation detected after stroke, and how this should inform poststroke workup, and secondary prevention strategies. Herein, we provide a synthesis of the current understanding surrounding the patient phenotypes that experience ESUS strokes, and previous, ongoing, and anticipated clinical trials that will guide earlier and later secondary prevention strategies and poststroke cardiac investigations.

Abstract
Closure of a patent foramen ovale (PFO) in patients after cryptogenic/cardioembolic stroke is recommended by current guidelines for patients who are 16-60 years of age with a high-risk PFO (class of recommendation A, level of evidence I). The use of double-disk occlusion devices followed by antiplatelet therapy is recommended. The procedure of interventional PFO closure compared with other interventions in cardiology is rather easy to learn. However, it should be performed carefully to avoid postinterventional complications. The number needed to treat (NNT) to avoid one stroke in 5 years in the RESPECT trial was 42, in the CLOSE trial even lower with 20. In the REDUCE trial, the NNT was 28 at 2 years. This can be reduced by longer follow-up, e.g., at 10 years the NNT is 18. While other conditions such as migraine are currently under investigation with respect to the impact of PFO closure, sufficiently powered trials are lacking so that closure in diseases other than stroke should always be individualized.

Abstract
A 34-year-old man with a medical history of injection drug use presented with 2 weeks of weakness, nausea, vomiting and septic shock secondary to infective endocarditis of a native tricuspid valve. On admission, CT chest demonstrated multiple cavitary lesions as well as numerous small infarcts seen on MRI brain concerning for systemic septic emboli. Subsequent transthoracic echo with bubble study revealed a large patent foramen ovale (PFO). The patient later received surgical debulking of his tricuspid valve vegetation with AngioVac. Subsequently, PFO closure was performed with a NobleStitch device. The case presented here demonstrates the importance of having a high index of suspicion with right-sided endocarditis and the development of other systemic signs and symptoms. It also underscores the necessity of a multidisciplinary team of cardiologists, surgeons, infectious disease specialists and intensivists in the treatment of these complicated patients.

Abstract
PURPOSE OF REVIEW Recent data have changed the landscape of patent foramen ovale (PFO) closure for secondary stroke prevention. This review synthesizes the data and provides a framework for optimal management of stroke patients with PFO. RECENT FINDINGS The cumulative evidence indicates that PFO closure reduces the risk of recurrent stroke in carefully selected young cryptogenic stroke patients, with an annualized risk reduction of ∼0.6%. The benefit of PFO closure is particularly evident in patients with embolic appearing strokes, large right-to-left shunt, or an associated atrial septal aneurysm. There may be little or no benefit in patients with small deep infarcts, a small PFO, or an indication for long-term anticoagulation. Closure is accompanied by a small risk of major procedural complication and atrial fibrillation. SUMMARY The annual risk of stroke from PFO is low relative to other stroke mechanisms, but the life-time cumulative risk in young patients who have experienced a prior stroke may be substantial, in which case the absolute benefit of closure is likely impactful. PFO is highly prevalent in the general population, present in about one in four adults, and should not be considered to be the cause of the stroke until a thorough workup has excluded alternative mechanisms.

Abstract
Cardiovascular disease remains a major contributor to morbidity and mortality in the US and elsewhere, and stroke is a leading cause of disability worldwide. Despite recent success in diminishing stroke incidence in the general US population, in parallel there is now a concerning propensity for strokes to happen at younger ages. Specifically, the incidence of stroke for US adults 20-44 years of age increased from 17 per 100,000 US adults in 1993 to 28 per 100,000 in 2015. Occurrence of strokes in young adults is particularly problematic as these patients are often affected by physical disability, depression, cognitive impairment and loss of productivity, all of which have vast personal, social and economic implications. These concerning trends among young adults are likely due to increasing trends in the prevalence of modifiable risk factors amongst this population including hypertension, hyperlipidemia, obesity and diabetes, highlighting the importance of early detection and aggressive prevention strategies in the general population at early ages. In parallel and compounding to the issue, troublesome trends are evident regarding increasing rates of substance abuse among young adults. Higher rates of strokes have been noted particularly among young African Americans, indicating the need for tailored prevention and social efforts targeting this and other vulnerable groups, including the primordial prevention of risk factors in the first place, reducing stroke rates in the presence of prevalent risk factors such as hypertension, and improving outcomes through enhanced healthcare access. In this narrative review we aim to emphasize the importance of stroke in young adults as a growing public health issue and increase awareness among clinicians and the public health sector. For this purpose, we summarize the available data on stroke in young adults and discuss the underlying epidemiology, etiology, risk factors, prognosis and opportunities for timely prevention of stroke specifically at young ages. Furthermore, this review highlights the gaps in knowledge and proposes future directions moving forward.

Abstract
Patent foramen ovale (PFO) is a common abnormality affecting between 20% and 34% of the adult population. For most people, it is a benign finding; however, in some people, the PFO can open widely to enable paradoxical embolus to transit from the venous to arterial circulation, which is associated with stroke and systemic embolisation. Percutaneous closure of the PFO in patients with cryptogenic stroke has been undertaken for a number of years, and a number of purpose-specific septal occluders have been marketed. Recent randomised control trials have demonstrated that closure of PFO in patients with cryptogenic stroke is associated with reduced rates of recurrent stroke. After a brief overview of the anatomy of a PFO, this article considers the evidence for PFO closure in cryptogenic stroke. The article also addresses other potential indications for closure, including systemic arterial embolisation, decompression sickness, platypnoea-orthodeoxia syndrome and migraine with aura. The article lays out the pre-procedural investigations and preparation for the procedure. Finally, the article gives an overview of the procedure itself, including discussion of closure devices.

Abstract
BACKGROUND Stroke is a common neurological disorder and may present with visual symptoms. A thorough workup is warranted to determine the underlying cause of stroke to optimize secondary prevention. Despite a full workup, a high-risk mechanism may not be identified. Optimal treatment in this patient population has been the subject of recent research, particularly with regard to low-risk stroke mechanisms such as patent foramen ovale (PFO). EVIDENCE ACQUISITION Using PubMed and published stroke guidelines, an evidence-based literature review was performed. RESULTS In this review, we compare cryptogenic stroke with the newer concept of embolic stroke of undetermined source, summarize the most common causes presumed to underlie these strokes, and review the evidence for optimal antithrombotic management. We also review recent clinical trials demonstrating a benefit for percutaneous closure of PFO for secondary stroke prevention in select patients. CONCLUSIONS Stroke management is based on evaluation of individual patient-risk factors. Evaluation and treatment is ideally directed by a vascular neurologist to ensure optimal secondary prevention, especially in cases where an underlying etiology is not identified on initial workup.

Abstract
Interventional patent foramen ovale (PFO) closure should be performed in patients aged 16 to 60 years (after extensive neurological and cardiological diagnostic work-up) with a history of cryptogenic ischaemic stroke and patent foramen ovale, with moderate or extensive right-to-left shunt. In patients with cryptogenic ischaemic stroke and patent foramen ovale, who reject a PFO closure, there is no evidence of superiority of oral anticoagulation over antiplatelet therapy. Therefore, secondary prevention should be performed with aspirin or clopidogrel. Atrial fibrillation, pericardial tamponade, and pulmonary embolism are reported complications during and after implantation of an occluder. However, these events are so rare that they should not influence the recommendation for implantation. This article is an abridged and translated version of the guideline published in Nervenarzt: Diener, HC., für die Deutsche Gesellschaft für Neurologie (DGN), Grau, A.J. et al. Nervenarzt (2018) 89: 1143. 10.1007/s00115-018-0609-y.

Abstract
Patent foramen ovale (PFO) is a common abnormality affecting between 20% and 34% of the adult population. For most people it is a benign finding; however, in some the PFO can open widely, enabling a paradoxical embolus to transit from the venous to arterial circulation, which is associated with stroke and systemic embolisation. Percutaneous closure of PFO in patients with cryptogenic stroke has been undertaken for a number of years, and a number of purpose-specific septal occluders have been marketed. Recent randomised controlled trials have demonstrated that closure of PFO in patients with cryptogenic stroke is associated with reduced rates of recurrent stroke. After a brief overview of the anatomy of a PFO, this review considers the evidence for PFO closure in cryptogenic stroke. The review also addresses other potential indications for closure, including systemic embolisation, decompression sickness, platypnoea-orthodeoxia syndrome and migraine with aura. It lays out the pre-procedural investigations and preparation for the procedure. Finally, it gives an overview of the procedure itself, including discussion of closure devices.

Abstract
The aim of our study is to compare patent foramen ovale (PFO) closure versus medical treatment and antiplatelet versus anticoagulant therapy in patients with cryptogenic stroke (CS) and PFO. We conducted a systematic review and meta-analysis with trial sequential analysis (TSA) of randomized trials. Primary outcomes are stroke or transient ischemic attack (TIA) and all-cause mortality. Secondary outcomes are peripheral embolism, bleeding, serious adverse events, myocardial infarction and atrial dysrhythmias. We performed an intention to treat meta-analysis with a random-effects model. We include six trials (3677 patients, mean age 47.3 years, 55.8% men). PFO closure is associated with a lower recurrence of stroke or TIA at a mean follow-up of 3.88 years compared to medical therapy [risk ratio (RR) 0.55, 95% CI 0.38-0.81; I2 = 40%]. The TSA confirms this result. No difference is found in mortality (RR 0.74, 95% CI 0.35-1.60; I2 = 0%), while PFO closure is associated with a higher incidence of atrial dysrhythmias (RR 4.55, 95% CI 2.16-9.60; I2 = 25%). The rate of the other outcomes is not different among the two groups. The comparison between anticoagulant and antiplatelet therapy shows no difference in terms of stroke recurrence, mortality and bleeding. There is conclusive evidence that PFO closure reduces the recurrence of stroke or TIA in patients younger than 60 years of age with CS. More data are warranted to assess the consequences of the increase in atrial dysrhythmias and the advantage of PFO closure over anticoagulants.

Abstract
Stroke is the second leading cause of death globally and can lead to significant adverse outcomes in patients following the acute illness. Due to this high morbidity and mortality, adequate interventions can play a significant role in health outcomes. Patent foramen ovale is one of the major proposed causes of cryptogenic strokes and can be present in up to 25% of general population. In cryptogenic strokes, the relation of this structural heart defect is inversely proportional to age of patient. Here, we present three cases of cryptogenic strokes in patients with patent foramen ovale where it possibly plays a significant role. We demonstrate that in the younger age spectrum, patent foramen ovale plays a more significant role and treatment could prevent future stroke episodes.

Abstract
Cryptogenic strokes account for about 25% to 40% of total ischemic strokes, and 1 of the 3 of these have a patent foramen ovale (PFO). A meta-analysis concerning the effectiveness and safety of PFO closure in cryptogenic strokes or transient ischemic attacks (TIAs) was performed. We systematically searched Medline, Embase, and the Cochrane Library through April 2018. Eligible studies were randomized clinical trials. Primary and secondary end points were, respectively, stroke or TIA and stroke recurrences. We calculated risk ratios (RRs) and 95% confidence intervals (CIs) for all end points using fixed- and random-effects meta-analyses. Data were included from 6 trials involving 3560 patients. In the pooled analysis, PFO closure was superior to medical treatment for both primary (RR: 0.39; 95% CI: 0.18-0.82; P < .02) and secondary end points (RR: 0.58; 95% CI: 0.44-0.76; P < .001). Transcatheter closure significantly increased the risk of new-onset atrial fibrillation (AF; RR: 5.74; P < .001). Percutaneous closure is superior to medical treatment in reducing stroke and TIA recurrence, even if with a significant risk increasing for new-onset AF. These findings suggest that transcatheter closure is indicated in patients with cryptogenic strokes and large PFO.

Abstract
BACKGROUND Approximately 40-50% of patients with cryptogenic stroke have a patent foramen ovale (PFO). A concomitant atrial septal aneurysm aggravates the risk of recurrent stroke. OBJECTIVE The most important changes regarding the evidence for interventional closure of a PFO in patients with cryptogenic stroke are described. This includes the prerequisites for making a diagnosis and the indications for interventional treatment. The article also provides an overview about platelet aggregation inhibitor treatment with and without oral anticoagulation. CURRENT DATA The balance between benefits and risks of interventional versus pharmaceutical treatment in patients with cryptogenic stroke and PFO has so far not been sufficiently proven. In 2017 two prospective randomized trials (CLOSE and REDUCE) and the long-term follow-up results of the RESPECT study were published, followed by the results of the DEFENSE-PFO study in 2018. A better assessment of the weighing up of the treatment options can now be made. All four studies showed that the interventional treatment of PFO is superior to pharmaceutical treatment alone for patients with cryptogenic stroke under 60 years of age. CONCLUSION There was a significant reduction in the incidence of recurrent stroke in patients with interventional PFO closure compared with pharmaceutical treatment. The complication rate of PFO closure is very low and younger patients (<60 years) in particular benefit from PFO closure.

Abstract
BACKGROUND Previous review from randomized controlled trials (RCT) showed that patients with cryptogenic stroke may benefit from patent foramen ovale (PFO) closure. However, the findings from the systematic review were not clear when observational studies were also included. METHODS We searched MEDLINE, Embase, and Cochrane databases. The primary endpoints were recurrent stroke or transient ischemic attack (TIA). The secondary outcomes were all-cause death, atrial fibrillation (AF), and hemorrhagic events. RESULTS Five randomized trials and fourteen observational studies (6301 participants) were eligible. PFO closure was superior to medical therapy for stroke prevention risk ratios ([RR], 0.38; 95% CI, 0.24-0.60), but showed increased risk of AF (RR, 4.96; 95% CI, 2.31-10.7). There was no significant difference in TIA recurrence, death, and hemorrhagic events. Subgroup analyses showed that patients with factors such as substantial residual shunt, the presence of atrial septal aneurysm (ASA), male, and age <45 years had a lower risk of recurrent stroke when PFOs were closed. CONCLUSIONS In patients with cryptogenic stroke, PFO closure does appeared to be superior to medical therapy in stroke prevention, with an increased incidence of AF. Male, age <45 years, substantial residual shunt, and the history of ASA are the factors that will predict the benefit when PFO is closed.

Abstract
A patent foramen ovale (PFO) is a highly prevalent finding in cryptogenic ischaemic stroke, particularly in young adults. A common challenge in clinical practice is to distinguish between incidental and pathogenic PFO. Some clinical features and tools such as the Risk of Paradoxical Embolism score may help determining the probability of a stroke-related PFO. Nonetheless, the best therapeutic option to reduce stroke recurrence after a cryptogenic stroke with PFO has been a matter of debate for a long time. We review the mechanisms of stroke-related PFO, together with its clinical features and diagnostic criteria. In addition, we focus on the methodological details and results from new studies in the field of secondary prevention. In contrast to prior evidence, the data from three recent clinical trials and an updated meta-analysis favour PFO closure over medical treatment after cryptogenic stroke/TIA for the prevention of stroke recurrence. The PFO closure device procedure is not associated with higher mortality or cardiovascular events, except for a small increase in the occurrence of transient atrial fibrillation. Furthermore, the benefit of PFO closure was higher among those with atrial septal aneurysm and PFO with large right-to-left shunt. Future studies should address pending issues such as the option for anticoagulants or antiplatelet in patients not undergoing closure, the duration of antiplatelet treatment after PFO closure and the role of PFO closure in patients older than 60.
