Incorporation of robotic automated transcranial Doppler to screen for patent foramen ovale (PFO) and quantify right-to-left shunt severity in the evaluation of ischemic stroke patients for etiology and PFO management. Front Neurol 2025; 15:1481817. [PMID: 40017730 PMCID: PMC11866324 DOI: 10.3389/fneur.2024.1481817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2024] [Accepted: 12/18/2024] [Indexed: 03/01/2025] Open
Abstract
Background Right-to-left shunt (RLS) associated with patent foramen ovale (PFO) is common among cryptogenic strokes. Current diagnostic tools have limitations. Transthoratic echocardiography (TTE) is not as sensitive as Transesophageal echocardiography (TEE), TEE is invasive, and manual transcranial Doppler (TCD) requires trained staff to operate. Robotic automated TCD (raTCD) may be feasible and comparable to manual TCD. The study's purpose was to determine the rate of RLS detection using raTCD and combine the Spencer Logarithmic Scale (SLS) with the Risk of Paradoxical Embolism (RoPE) to identify patients at risk of PFO associated stroke or TIA. Methods This single-center retrospective cohort study included adult patients (≥18 y/o) admitted from December 2021 to December 2022 with a stroke or transient ischemic attack. Those with no bone window or stroke mimics were excluded. Patients with an RLS on raTCD received a second scan at the physician's discretion. The SLS combined with the RoPE score was used to generate a modified screening PFO-Associated Stroke Causal Likelihood (msPASCAL) classification. Results Of 212 patients who received raTCD, the mean age was 56, 14% were >65 years old, most were white (72%), predominantly male (59%), 52% had cryptogenic strokes, and 59% had an RLS. Most patients were able to perform Valsalva (89%) during raTCD. Of those with an RLS, 56% had an SLS of 1-2, while 44% had an SLS of 3-5. There were no significant differences in characteristics by SLS. Most patients with SLS grades 1-2 were classified using msPASCAL as unlikely to have PFO as stroke etiology (n = 55, 44%). A small number of large SLS grades 3-5 were considered probable for having a PFO-associated stroke while the rest were classified as possible (n = 38, 30.4%). Eight patients with positive RLS on raTCD had a negative TTE with bubbles; most of those had small RLS on raTCD (n = 5, 63%) or could not Valsalva due to sedation ((n = 6, 75%). Discussion This study supports the feasibility of utilizing raTCD for RLS detection. The modified screening PASCAL classification can be generated for RLS patients and may be used to guide subsequent evaluation and management.

Cardiovasc Diagn Ther 2024; 14:1048-1057. [PMID: 39790191 PMCID: PMC11707468 DOI: 10.21037/cdt-24-288] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2024] [Accepted: 11/05/2024] [Indexed: 01/12/2025]
Abstract
Background About 30% of ischemic strokes do not have a clear cause, which is called cryptogenic stroke (CS). Increasing evidence suggests a potential link between CS and right-to-left shunt (RLS). RLS may lead to CS via paradoxical embolic mechanism. Hence, current study aims to explore the correlation between different RLS indexes and the occurrence of CS and its clinical diagnostic value in CS. Methods A total of 117 patients diagnosed with CS from October 2020 to June 2024 were randomly collected, and 93 patients with only headache and dizziness were randomly collected as the control group. All patients underwent agitated saline contrast echocardiography (ASCE) and the semi-quantitative classification, type and duration of RLS were analyzed. Spearman correlation analysis was used to analyze the correlation between RLS grade and type and the occurrence of CS, and the correlation between RLS duration and RLS grade and type. The efficacy of different RLS grades, types and durations in the diagnosis of CS were analyzed by receiver operating characteristic (ROC) curve. Results The included population ranged in age from 20-73 years, with 90 males and 120 females. There was no significant difference in basic data (e.g., gender, smoking history, drinking history, and the number of people with hypertension and diabetes) and serum biological indicators [triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL) and low-density lipoprotein (LDL)] between the CS group and the control group (all P>0.05). The proportion of RLS (77.78%) in the CS group was significantly higher than that in the control group (35.48%) (P<0.001). Spearman correlation analysis showed that RLS grade (r=0.569) and type (r=0.346) were significantly correlated with the occurrence of CS (both P<0.001). In addition, RLS duration was significantly correlated with RLS type (r=0.902, P<0.001), but not with RLS size (P>0.05). ROC curve analysis showed that RLS grade had the highest area under the curve (AUC) in CS diagnosis, which was 0.807 [95% confidence interval (CI): 0.748-0.866], the diagnostic sensitivity was 68.4%, and the specificity was 87.1%. In addition, the diagnostic AUC of RLS type and RLS duration in CS were similar, at 0.700 (95% CI: 0.626-0.773) and 0.707 (95% CI: 0.634-0.780), respectively. Conclusions RLS grade and RLS type are significantly correlated with the occurrence of CS. As an auxiliary means of CS diagnosis, RLS grade can effectively reduce the misdiagnosis rate of CS, which is of great clinical significance for early detection of CS risk.

Abstract
Background The closure of a patent foramen ovale (PFO) using transseptal puncture has particular advantages and disadvantages. Thus, transseptal puncture should be re-evaluated in detail. Aims We aimed to assess the effectiveness of the detailed transseptal puncture technique in patients who underwent PFO closure due to cryptogenic stroke or transient ischemic attack in terms of residual shunts and atrial fibrillation. Methods We prospectively analyzed 144 consecutive patients who underwent PFO closure by the detailed transseptal puncture technique between February 2013 and April 2023 in two centers. All of the patients had a >10 mm long-tunnel PFO. Results The procedural success rate was 100%. However, after the procedure, moderate pericardial effusion developed in one patient (0.7%) and an acute pulmonary embolism related to femoral vein thrombosis was observed in one patient (0.7%) during the first month. Complications related to the procedure were noted in two patients (1.4%) during the first month of follow-up. Residual shunts were observed in 1.4% of cases after PFO closure. Conclusion We demonstrated that the detailed transseptal technique is safe and effective for PFO closure. The detailed transseptal PFO closure technique significantly reduced the risk of atrial fibrillation, and the occurrence of residual shunts was significantly low following the closure.

Graefes Arch Clin Exp Ophthalmol 2024; 262:3577-3587.

Abstract
PURPOSE To understand the etiology, work-up, and secondary systemic and ocular events of retinal artery occlusion (RAO) in young patients (≤ 45 years old) without typical cardiovascular risk factors. METHODS Retrospective longitudinal case series of 18 young patients with RAO and without typical cardiovascular risk factors evaluated at the University of Michigan Medicine Health System between the year 2000 and 2022. Laboratory and imaging studies performed at the time of RAO diagnosis, along with systemic and ocular events during follow-up, were recorded. These data were combined with data from a literature review of 74 similar patients experiencing a RAO. RESULTS Fifteen (83%) of patients were female and 10 (56%) suffered a branch retinal artery occlusion (BRAO). 56% of patients had one risk factor associated with cryptogenic stroke, most commonly a migraine history (33%). The most frequent etiology of RAO was vasculitis (28%), followed by idiopathic (22%) and patent foramen ovale (PFO, 17%). Three out of four patients with idiopathic RAOs developed new migraines around the time of RAO diagnosis, whereas none of the patients with a clear etiology had new onset migraines (n = 14). No patients suffered a stroke or myocardial infarction (MI) in the follow-up period (average 3.6 years ± 3.2 years). Two patients (11%) suffered a repeat RAO, both of whom were diagnosed with a vasculitis. Patients with isolated retinal vasculitis required repeat fluorescein angiograms for up to 2 years after the initial event to definitively identify the vasculitic etiology of the RAO. When our data are pooled with similarly healthy patients from previously published RAO series, structural/functional cardiac abnormalities and vasculitides are the most common identifiable etiologies for RAOs in this group. CONCLUSION The most common identifiable etiologies of RAO in young patients with low cardiovascular risk are structural/functional cardiac abnormalities and vasculitides, with a small range of additional causes/associations accounting for remaining cases. We suggest a focused work-up algorithm to rapidly identify etiologies in this group while minimizing unnecessary testing. The long-term risk of systemic or ocular secondary events in these patients is low regardless of the etiology of their RAO.

Abstract
Transoesophageal echocardiography (TOE) is a well-established and valid imaging modality, providing more accurate and of higher quality information than transthoracic echocardiography (TTE) for several specific diagnoses and recently a useful guide of an increasing number of catheter-based and surgical interventions. The present paper represents an effort by the Echocardiography Working Group (WG) of the Hellenic Society of Cardiology to state the essential steps of the TOE exam performed beyond the echo lab: a) in the operating rooms intraoperatively during either transcatheter interventions, or cardiothoracic surgery and b) in the intensive care unit for critically ill patients' monitoring. This paper includes information and tips and tricks about the pre-procedural evaluation, the procedural echocardiographic guidance, and post-procedural evaluation of the result and potential complications.

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.

JOURNAL OF THE SOCIETY FOR CARDIOVASCULAR ANGIOGRAPHY & INTERVENTIONS 2024; 3:101930. [PMID: 39132008 PMCID: PMC11308160 DOI: 10.1016/j.jscai.2024.101930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 02/26/2024] [Accepted: 03/04/2024] [Indexed: 08/13/2024]
Abstract
Background Patent foramen ovale (PFO) is seen in 25% of the general population but in up to 50% of patients ≤60 years old with cryptogenic strokes. Trials have shown that PFO closure vs medical therapy reduces the risk of future strokes. PFO closure may cause atrial fibrillation (AF), with prior trials reporting an incidence of 2% to 11.9%. However, the true incidence of AF after PFO closure is unknown due to limitations in prior studies for long-term monitoring. Methods This is a retrospective observational study at a single center. Patients who underwent PFO closure and had an implantable loop recorder prior to PFO closure were included. The final review included 38 patients who had at least 2 months of implantable loop recorder data post-PFO closure. Results Ten out of 38 (26%) patients developed AF post-PFO closure. The median time to the first episode of AF was 3.95 weeks, with 40% having their first AF episode after 3 months. Median duration of AF episodes was 1 hour. One hundred percent had spontaneous termination of AF. Of the AF patients, 70% were started on oral anticoagulant therapy. Conclusions Our review shows a higher incidence of AF post-PFO closure as compared with most reported prior studies. We recommend larger prospective studies to explore the true incidence of AF post-PFO closure, its clinical impact, and subsequent stroke risk.

Abstract
Patent foramen ovale (PFO) is a prevalent congenital cardiac anomaly associated with a persistent opening between the atrial septum, allowing communication between the left and right atria. Despite often being asymptomatic, PFO can lead to various clinical presentations, including cryptogenic stroke and other embolic events. Transient visual disturbances, alterations in the visual field, migraine with aura, impaired eye movement and endogenous eye infections may prompt patients to seek ophthalmological consultation. Understanding these diverse clinical scenarios is crucial for early detection, appropriate management and mitigating the morbidity burden associated with PFO. This narrative review aims at examining the spectrum of clinical presentations of ocular pictures associated with PFO. The pathophysiology, diagnosis and treatment methods for PFO will be described, emphasizing the importance of a multidisciplinary approach involving ophthalmologists, cardiologists, neurologists and imaging specialists. In the future, prospective studies and clinical trials are warranted to provide further insights into the preventive role and optimal therapeutic strategies for managing PFO-related ocular complications, ultimately guiding clinical decision making and optimizing patient care.

Abstract
Stroke ranks among the prevalent factors contributing to child mortality. Cryptogenic stroke has been linked with patent foramen ovale (PFO), which has been suggested as a possible route for thrombus, gas bubble, or another particulate that comes through systemic venous circulation to the brain artery. Yet, the most effective approach for managing cryptogenic stroke involving a PFO remains uncertain. This case aims to report a PFO patient with complications of stroke. A 5-year-old girl was admitted to the emergency department at Dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia, after experiencing numbness and weakness on her right side and a sudden onset of slurred speech three days before admission. Laboratory findings only showed leukocytosis, while coagulation tests were normal. Non-contrast brain CT revealed an occurrence of cerebral infarction in the left hemisphere. Transcranial Doppler showed no atherosclerosis in cerebral arteries, and carotid Doppler ultrasound results were reported normal. Transthoracic echocardiography showed a PFO with the right-to-left shunt. The patient was treated with an intravenous infusion of citicoline 250 mg twice daily, oral aspirin 80 mg daily, and oral mecobalamin 250 mg daily and was planned to undergo a PFO closure procedure. However, the patient's parents rejected the plan to perform a PFO closure procedure. PFO has the potential to be a contributing factor to cryptogenic stroke among children. PFO closure followed by antiplatelet therapy for a couple of months has been shown to outperform medical therapy alone. However, additional evaluation should be done to cautiously consider the PFO closure procedure in children.

Abstract
A South Asian male in his early 60s presented with acute-onset dyspnoea on postoperative day 4 after undergoing middle hepatic vein sacrificing partial liver resection for epithelioid angiomyolipoma. The patient's SpO2 on presentation was 65% in standing position which improved to 90% in left lateral decubitus. He was suspected of having platypnea-orthodeoxia syndrome (POS) which was confirmed on echocardiogram with microbubble contrast showing a large intracardiac right-to-left shunt. The patient was taken up for transcatheter closure of patent foramen ovale (PFO). A 30 mm Amplatzer PFO Occluder was deployed across the PFO which reduced the intracardiac shunt resulting in an improved arterial saturation as well as immediate relief of patient's symptoms. This case illustrates the importance of suspecting and recognising POS clinically as well as the efficacy of transcatheter closure of PFO in such cases leading to resolution of hypoxaemia in a short span of time.

Abstract
Paradoxical embolism occurs when a thrombus crosses an intracardiac defect into the systemic circulation. Here, we present the case of a 35-yearold male kidney transplant recipient with a cerebral paradoxical embolism associated with a spontaneous venous thromboembolism. This patient had recurrent deep venous thrombosis and showering emboli to the lung and paradoxically to the brain through patent foramen ovale, and we treated him successfully. The role of bubble echocardiography was essential in diagnosis to avoid contrast-induced nephropathy. This is the first successfully managed case of a kidney transplant recipient with recurrent idiopathic deep vein thrombosis, pulmonary embolism, and cerebral paradoxical embolism. Bubble echocardiography was an excellent alternative to contrast angiography to avoid nephrotoxicity. Vitamin K antagonists are superior to direct oral anticoagulants, especially among nonadherent/noncompliant patients.

Abstract
Atrial fibrillation (AF) and stroke remain a major cause of morbidity and mortality. The two conditions shared common co-morbidities and risk factors. AF-related strokes are associated with worse clinical outcomes and higher mortality compared to non-AF-related. Early detection of AF is vital for prevention. While various scores have been developed to predict AF in such a high-risk group, they are yet to incorporated into clinical guidelines. Novel markers and predictors of AF including coronary and intracranial arterial calcification have also been studied. There are also ongoing debates on the management of acute stroke in patients with AF, and those who experienced breakthrough stroke while on oral anticoagulants. We provided an overview of the complex interplay between AF and stroke, as well as the treatment and secondary prevention of stroke in AF. We also comprehensively discussed the current evidence and the ongoing conundrums, and highlighted the future directions on the topic.

Transcatheter closure of patent foramen ovale using the Cocoon occluder: A multicenter retrospective study. Hellenic J Cardiol 2024; 75:21-25. [PMID: 37127207 DOI: 10.1016/j.hjc.2023.04.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 03/28/2023] [Accepted: 04/28/2023] [Indexed: 05/03/2023] Open
Abstract
BACKGROUND The Cocoon patent foramen ovale (PFO) occluder is a new device especially designed for transcatheter closure of PFO. This occluder has some distinctive structural modifications aimed at reducing the risk of major complications of transcatheter PFO closure. In this report we present our initial experience to evaluate the efficacy and safety of the Cocoon PFO occluder in 253 patients who underwent transcatheter PFO closure. METHODS The study cohort included 253 patients (median age 45 years) with embolic stroke of undetermined source who underwent attempted transcatheter closure of PFO for secondary prevention of paradoxical embolism. Patients were enrolled retrospectively from five sites in Greece and one in Romania between December 2016 and January 2021, and the median follow-up period was 28 months (range 12-48 months). Clinical and laboratory data from each participating center were sent to an electronic registry for evaluation and statistical analysis. RESULTS The Cocoon PFO occluder was permanently implanted in all patients. At 6 months, complete occlusion of PFO was observed in 251/253 (99.2%) patients. Three (1.2%) patients had a trivial residual shunt. Thrombus formation on the device, which was successfully treated with recombinant tissue plasminogen activator infusion, was observed in one (0.4%) patient. No other complications occurred. During a median follow-up period of 28 months, 3 (1.2%) patients, aged 64-67 years, developed new onset paroxysmal atrial fibrillation. No neurologic events, cardiac erosions, allergic reactions to nickel, or thrombus formation occurred. CONCLUSION The Cocoon PFO occluder is an effective and safe device that adds to our armamentarium for transcatheter closure of PFO.

Abstract
Over 750,000 individuals suffer from stroke annually in the United States, with 87% of these strokes being ischemic in nature. Roughly 40% of ischemic strokes occur in individuals 60 years of age or under. A quarter of all ischemic strokes have no identifiable cause despite extensive workup and are deemed cryptogenic in nature. Patent Foramen Ovales (PFO) has been postulated in stroke causation by either paradoxical embolization or platelet activation in the tunnel of the defect. The incidence of PFO is reported to be 15-25% in the general population but rises to 40% in patients with cryptogenic stroke. While the initial trials evaluating PFO closures were non-revealing, subsequent long-term follow-ups, as well as recent trials evaluating PFO closures in cryptogenic stroke patients 60 years of age or under, demonstrated the superiority of percutaneous closure compared to medical therapy alone, leading to FDA approval of PFO closure devices. In this review, we review the diagnosis of PFO, postulated stroke mechanisms, literature supporting PFO closure, patient selection for percutaneous closure, procedural considerations, and associated procedural complications.

Abstract
AIMS Atrial fibrillation (AF) is detected in over 30% of patients following an embolic stroke of undetermined source (ESUS) when monitored with an implantable loop recorder (ILR). Identifying AF in ESUS survivors has significant therapeutic implications, and AF risk is essential to guide screening with long-term monitoring. The present study aimed to establish the role of left atrial (LA) function in subsequent AF identification and develop a risk model for AF in ESUS. METHODS AND RESULTS We conducted a single-centre retrospective case-control study including all patients with ESUS referred to our institution for ILR implantation from December 2009 to September 2019. We recorded clinical variables at baseline and analysed transthoracic echocardiograms in sinus rhythm. Univariate and multivariable analyses were performed to inform variables associated with AF. Lasso regression analysis was used to develop a risk prediction model for AF. The risk model was internally validated using bootstrapping. Three hundred and twenty-three patients with ESUS underwent ILR implantation. In the ESUS population, 293 had a stroke, whereas 30 had suffered a transient ischaemic attack as adjudicated by a senior stroke physician. Atrial fibrillation of any duration was detected in 47.1%. The mean follow-up was 710 days. Following lasso regression with backwards elimination, we combined increasing lateral PA (the time interval from the beginning of the P wave on the surface electrocardiogram to the beginning of the A' wave on pulsed wave tissue Doppler of the lateral mitral annulus) [odds ratio (OR) 1.011], increasing Age (OR 1.035), higher Diastolic blood pressure (OR 1.027), and abnormal LA reservoir Strain (OR 0.973) into a new PADS score. The probability of identifying AF can be estimated using the formula. Model discrimination was good [area under the curve (AUC) 0.72]. The PADS score was internally validated using bootstrapping with 1000 samples of 150 patients showing consistent results with an AUC of 0.73. CONCLUSION The novel PADS score can identify the risk of AF on prolonged monitoring with ILR following ESUS and should be considered a dedicated risk stratification tool for decision-making regarding the screening strategy for AF in stroke.

Abstract
INTRODUCTION Patent foramen ovale (PFO) occurs in 25% of the general population and in 40% of cryptogenic ischemic stroke patients. Recent trials support PFO closure in selected patients with cryptogenic stroke. We examined the outcomes of transcatheter PFO closure in a real-world study cohort with cryptogenic stroke. METHODS Consecutive ischemic stroke patients who were classified as cryptogenic on the TOAST aetiology and diagnosed with a PFO were included. All patients underwent either transcatheter PFO closure or medical therapy. A 2:1 propensity score matching by sex and Risk-of-Paradoxical-Embolism (RoPE) score was performed. Multivariable regression models adjusted for sex and RoPE score. RESULTS Our cohort comprised 232 patients with mean age 44.3 years (SD 10.8) and median follow-up 1486.5 days. 33.2% were female. PFO closure (n=84) and medical therapy (n=148) groups were well-matched with <10% mean-difference in sex and RoPE score. Two patients in the treated group (2.4%) and seven in the control group (4.7%) had a recurrent ischemic stroke event. Multivariable Cox regression demonstrated a hazard-ratio of 0.26 (95%CI 0.03-2.13, P=0.21) for PFO closure compared to control. The incidence of atrial fibrillation (AF) detected post-PFO closure was similar between the treated and control (1.19% vs 1.35%, multivariable logistic regression odds-ratio 0.90, 95%CI 0.04-9.81, P=0.94). There were no major periprocedural complications documented. The difference in restricted mean survival-time free from stroke at two years between treated and control was 26.2 days (95%CI 5.52-46.85, P=0.013). CONCLUSIONS In this Asian cohort, we report a low incidence of ischemic stroke recurrence and new-onset AF in patients who underwent PFO closure. When compared to the medical therapy group, there was no significant difference in the incidence of stroke recurrence and new-onset AF. Further studies involving larger real-world cohorts are warranted to identify patients who are more likely to benefit from PFO closure.

Abstract
Background and Objectives Multidisciplinary clinics have been shown to improve care. Patients with patent foramen ovale (PFO)-associated stroke need evaluation by cardiology and neurology specialists. We report our experience creating a multidisciplinary Structural Heart Brain Clinic (HBC) with a focus on patients with PFO-associated stroke. Methods Demographic and clinical data were retrospectively collected for patients with PFO-associated ischemic stroke. Patients with PFO-associated stroke were divided into a standard care group and Heart Brain Clinic group for analysis. Outcome measures included time from stroke to PFO closure and number of clinic visits before decision regarding closure. Nonparametric analysis evaluated differences in median time to visit and clinical decision, while the chi square analysis compared differences in categorical variables between groups. Results From February 2017 to December 2021, 120 patients were evaluated for PFO-associated stroke. The Structural HBC began in 12/2018 with coordination between Departments of Neurology and Cardiology. For this analysis, 41 patients were considered in the standard care group and 79 patients in the HBC group. During data analysis, 107 patients had received recommendations about PFO closure. HBC patients required fewer clinic visits (p = 0.001) before decision about closure; however, among patients who underwent PFO closure, there was no significant difference in weeks from stroke to PFO closure. Clinicians were more likely to recommend against PFO closure among patients seen in HBC compared with those seen in standard care (p = 0.021). Discussion Our data demonstrate that a multidisciplinary, patient-centered approach to management of patients with PFO-associated ischemic stroke is feasible and may improve the quality of care in this younger patient population. The difference in recommendation to not pursue PFO closure between groups may reflect selection and referral bias. Additional work is needed to determine whether this approach improves other aspects of care and outcomes.

Comparative evaluation of intracardiac, transesophageal, and transthoracic echocardiography in the assessment of patent foramen ovale: A retrospective single-center study. Catheter Cardiovasc Interv 2023; 102:1348-1356. [PMID: 37681474 DOI: 10.1002/ccd.30825] [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: 04/23/2023] [Revised: 08/18/2023] [Accepted: 08/24/2023] [Indexed: 09/09/2023]
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.

Coronary air embolism during transcatheter patent foramen ovale closure for platypnea-orthodeoxia syndrome in a patient with severe respiratory disorder: a case report. Eur Heart J Case Rep 2023; 7:ytad521. [PMID: 37942356 PMCID: PMC10629690 DOI: 10.1093/ehjcr/ytad521] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 10/03/2023] [Accepted: 10/16/2023] [Indexed: 11/10/2023]
Abstract
Background Coronary air embolism (CAE) is a rare and life-threatening complication of endovascular procedures, mostly due to procedure-related causes. Case summary A 70-year-old man with severe respiratory disorder presented with patent foramen ovale (PFO)-related platypnea-orthodeoxia syndrome (POS). Transcatheter PFO closure was performed under local anaesthesia and intracardiac echocardiographic guidance. After a 5-Fr catheter was passed through the PFO via a 7-Fr femoral vein sheath, the patient suddenly coughed and breathed deeply. Thereafter, intracardiac echocardiography showed massive microbubbles in all cardiac chambers and the ascending aorta, and an electrocardiogram showed ST-segment elevations in the anterior and inferior leads. Emergency coronary angiography confirmed occlusion of the mid-left anterior descending artery, suggesting CAE. As the intracoronary infusion of saline, nitroglycerine, and nicorandil was ineffective, we performed air aspiration using a thrombectomy device, achieving coronary blood flow improvement and ST-segment resolution. Thereafter, positive pressure support using manual bag-valve-mask ventilation under intravenous sedation supported successful transcatheter PFO closure without further air embolization. Discussion In this case with severe respiratory dysfunction, spontaneous deep breathing (spontaneous Valsalva manoeuvre) caused negative intrathoracic pressure and large drops in intravascular pressure. This phenomenon might have induced air contamination during device advancement, either by entrapping or leaving residual air in the gaps between the catheter and the sheath. Additionally, PFO with right-to-left shunts is more likely to cause paradoxical air embolization. Thus, the spontaneous Valsalva manoeuvre should be avoided with appropriate respiratory management to prevent paradoxical air embolization, including CAE, during transcatheter PFO closure under local anaesthesia in severe respiratory dysfunction patients.

Abstract
Objectives Strokes are a major cause of morbidity and mortality. This study aimed to evaluate the effectiveness of routine cardiac investigations in identifying a cardioembolic aetiology for ischaemic strokes. Methods This retrospective study involved patients who presented with a stroke to the Sultan Qaboos University Hospital, Muscat, Oman, between January and December 2019. Results A total of 183 patients (mean age = 66.2 ± 13.5 years), the majority of which were male (n = 109, 59.6%), were included. The common risk factors included hypertension (74.9%), diabetes (61.7%) and hyperlipidaemia (54.6%). The middle cerebral artery was the most common artery affected, in 44 patients (24.0%). On admission, 14 (7.6%) patients were in atrial fibrillation (AF), while the rest were in sinus rhythm. The 24-hour electrocardiogram (ECG) Holter monitoring revealed no abnormalities in 135 patients. AF was observed in 15 (8.1%) patients (inclusive of the 14 who had AF on resting ECG). Furthermore, 32 (17.4%) patients had evidence of non-sustained atrial arrhythmia, and nine (4.9%) had non-sustained ventricular tachycardia. Frequent supraventricular ectopics (>30/hour) was noted on 30 patients (16.3%), while five (2.7%) patients had a high ventricular ectopic burden (>10% burden). No significant abnormalities were noted in the echocardiograms of the patients; however, 10 out of 132 (7.5%) patients presented a positive bubble echo. Enlarged left atria were found in 24 (13.1%) patients. Conclusion The overall diagnostic yield of the abnormalities from routine cardiac testing for patients with stroke appears to be low. Targeted screening of patients with cryptogenic stroke, as suggested by newer guidelines, is recommended.

Abstract
BACKGROUND Sclerotherapy is a non-invasive procedure commonly used to treat superficial venous disease, vascular malformations and other ectatic vascular lesions. While extremely rare, sclerotherapy may be complicated by serious adverse events. OBJECTIVES To categorise contraindications to sclerotherapy based on the available scientific evidence. METHODS An international, multi-disciplinary panel of phlebologists reviewed the available scientific evidence and developed consensus where evidence was lacking or limited. RESULTS Absolute Contraindications to sclerotherapy where the risk of harm would outweigh any benefits include known hypersensitivity to sclerosing agents; acute venous thromboembolism (VTE); severe neurological or cardiac adverse events complicating a previous sclerotherapy treatment; severe acute systemic illness or infection; and critical limb ischaemia. Relative Contraindications to sclerotherapy where the potential benefits of the proposed treatment would outweigh the risk of harm or the risks may be mitigated by other measures include pregnancy, postpartum and breastfeeding; hypercoagulable states with risk of VTE; risk of neurological adverse events; risk of cardiac adverse events and poorly controlled chronic systemic illness. Conditions and circumstances where Warnings and Precautions should be considered before proceeding with sclerotherapy include risk of cutaneous necrosis or cosmetic complications such as pigmentation and telangiectatic matting; intake of medications such as the oral contraceptive and other exogenous oestrogens, disulfiram and minocycline; and psychosocial factors and psychiatric comorbidities that may increase the risk of adverse events or compromise optimal treatment outcomes. CONCLUSIONS Sclerotherapy can achieve safe clinical outcomes provided that (1) patient-related risk factors and in particular all material risks are (1a) adequately identified and the risk benefit ratio is clearly and openly discussed with treatment candidates within a reasonable timeframe prior to the actual procedure; (1b) when an individual is not a suitable candidate for the proposed intervention, conservative treatment options including the option of 'no intervention as a treatment option' are discussed; (1c) complex cases are referred for treatment in controlled and standardised settings and by practitioners with more expertise in the field; (1d) only suitable individuals with no absolute contraindications or those with relative contraindications where the benefits outweigh the risks are offered intervention; (1e) if proceeding with intervention, appropriate prophylactic measures and other risk-mitigating strategies are adopted and appropriate follow-up is organised; and (2) procedure-related risk factors are minimised by ensuring the treating physicians (2a) have adequate training in general phlebology with additional training in duplex ultrasound, procedural phlebology and in particular sclerotherapy; (2b) maintain their knowledge and competency over time and (2c) review and optimise their treatment strategies and techniques on a regular basis to keep up with the ongoing progress in medical technology and contemporary scientific evidence.

Abstract
BACKGROUND Patent foramen ovale (PFO) is a congenital heart defect associated with an increased risk of cryptogenic stroke. We aimed to evaluate real-world outcomes of adult patients undergoing transcatheter PFO closure with the Amplatzer PFO Occluder. METHODS In this single centre, retrospective cohort study, we linked a detailed clinical registry with provincial administrative databases to obtain short and long-term outcomes. Validated algorithms were used to established baseline comorbidities and adverse outcomes. RESULTS Between 1999 and 2017, 479 patients had PFO closure with an Amplatzer PFO Occluder. The average age of the patients was 47.3 years (standard deviation (SD) = 12.4), and 54.7% were males. The procedural success was 100%, and 96% of patients were discharged on the same day. Any in-hospital complication was observed in 2.5% (n = 12) of patients. At 30 days post-discharge, 18% of patients had an ED visit and 5% a hospitalization. Over a mean follow-up of 9.1 (SD = 3.8) years, 4% experienced TIA, 1.5% stroke, and 7.6% atrial fibrillation. The composite outcome of stroke/TIA/death was observed in 10.9% of patients (1.22 events per 100 person-years). Patients >60 years old experienced higher rates of adverse events than younger patients. CONCLUSIONS In this large real-world cohort of patients with cryptogenic stroke, we observed excellent safety and effectiveness outcomes for PFO closure conducted with Amplatzer PFO Occluder, similar to randomized controlled trials or other long-term cohort studies. New onset atrial fibrillation was one of the most commonly adverse events. Future studies should investigate early post-discharge management of patients to prevent readmissions.

Abstract
Introduction Atrial Septal Defect/Patent Foramen Ovale (ASD/PFO) occlusion is performed to prevent paradoxical embolism and reduce the risk of recurrent ischemic stroke. Left atrial appendage (LAA) closure is used as an alternative to medical therapy of non-valvular atrial fibrillation for prevention of stroke. Multiple studies have examined performing LAA and ASD/PFO occlusion. However, the feasibility and safety of combined occlusion of the left atrial appendage and ASD/PFO are not clear, furthermore, these studies are limited by their small sample sizes and retrospective analysis. In this study, we aimed to systematically review and meta-analyze the feasibility and safety of combining left atrial appendage and ASD/PFO closure. Methods PubMed, Web of Science, CNKI, Cochrane Library, Embase, and WanFang database were searched up to April 2022 to identify peer-reviewed human studies on assessing the feasibility, safety, and efficacy of combining left atrial appendage and ASD/PFO closure. The primary outcome was calculated: procedural feasibility outcome and procedural safety outcome. Results A total of 10 articles, including 340 patients from multiple countries, were included in the analysis. The principal findings of our study are: compared with single LAA closure, (i) combining PFO/ASD occlusion and LAA closure had similar procedural success proportion (98.43%, 95% CI: 96.67-100.00%), (ii) similar safety event incidences developed (1.67%, 95% CI: 0.24-3.92%), subgroup analyzed safety event incidences in death was 0.00 (95% CI: 0.00-0.33%), cardiac tamponade was 0.87% (95% CI: 0.00-2.77%), device embolization was 0.00 (95% CI: 0.00-0.60%), major bleeding was 0.00 (95% CI: 0.00-0.33%), stroke was 0.00 (95% CI: 0.00-0.02%). Conclusion Although this systematic review and meta-analysis demonstrate the technical feasibility and safety of combining closure of PFO/ASD and LAA, further studies of sufficient sample size, long-term follow-up, and rigor endpoint criteria are yet needed to fully evaluate this combination procedure for its role in clinical outcomes.

[PMID: 36455524 PMCID: PMC10627487 DOI: 10.1159/000527791] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Accepted: 10/24/2022] [Indexed: 10/04/2023] Open
Abstract
INTRODUCTION A patent foramen ovale (PFO) may coexist with other potential embolic sources (PESs) in patients with embolic stroke of undetermined source (ESUS), leading to difficulty in attributing the stroke to either the PFO or other PESs. We aimed to investigate the prevalence and predictors of concomitant PESs in ESUS patients with PFOs. METHODS A retrospective cohort study was conducted in a tertiary stroke centre. Consecutive patients with ESUS and a concomitant PFO admitted between 2012 and 2021 were included in the study. Baseline characteristics and investigations as a part of stroke workup including echocardiographic and neuroimaging data were collected. PESs were adjudicated by 2 independent neurologists after reviewing the relevant workup. RESULTS Out of 1,487 ESUS patients, a total of 309 patients who had a concomitant PFO with mean age of 48.8 ± 13.2 years were identified during the study period. The median Risk of Paradoxical Embolism (RoPE) score for the study cohort was 6 (IQR 5-7.5). Of the 309 patients, 154 (49.8%) only had PFO, 105 (34.0%) patients had 1 other PES, 34 (11.0%) had 2 PES, and 16 (5.2%) had 3 or more PES. The most common PESs were atrial cardiopathy (23.9%), left ventricular dysfunction (22.0%), and cardiac valve disease (12.9%). The presence of additional PESs was associated with age ≥60 years (p < 0.001), RoPE score ≤6 (p ≤0.001), and the presence of comorbidities including diabetes mellitus (p = 0.004), hypertension (p≤ 0.001), and ischaemic heart disease (p = 0.011). CONCLUSION A large proportion of ESUS patients with PFOs had concomitant PESs. The presence of concomitant PESs was associated with older age and a lower RoPE score. Further, large cohort studies are warranted to investigate the significance of the PES and their overlap with PFOs in ESUS.

Abstract
We present a case of a woman with past medical history notable for mild COVID-19 infection who presented with dyspnea on exertion, then developed progressively worsening exertional desaturations and was found to have a patent foramen ovale (PFO). Extensive cardiopulmonary testing revealed no clear alternate etiology for her symptoms. After much discussion, she underwent successful closure of the PFO with complete resolution of her symptoms and significantly improved exertional desaturation.

Abstract
Disorders involving the vascular system of the brain are numerous and sundry. Atherosclerotic thromboembolism of large vessels and lacunar infarctions of small vessel disease are well known. Brain infarction due to cardioembolism is common as well, and even more so when diligently sought. Rupture of intracranial blood vessels results in subarachnoid and intraparenchymal hemorrhage. We present four cases of stroke of uncommon cause and remind clinicians to be open minded to the many possible causes of stroke, in particular because early recognition and treatment is often critical. Case 1 discusses a patient with inflammatory cerebral amyloid angiopathy. The presentation, ability to recur, and current treatment considerations are reviewed. Case 2 discusses microangiopathic thrombotic angiopathy. Diagnosis and treatment are considered. An association with interferon therapy and the evolving terminology of this and related conditions are discussed. Case 3 discusses intracranial hemorrhage secondary to acute promyelocytic leukemia. Patients with acute leukemias require aggressive management of their coagulopathy, thrombocytopenia, and the disease itself. Finally, Case 4 discusses ischemic stroke due to a paradoxical embolism in the setting of a patent foramen ovale (PFO). Both medical and surgical management of a PFO for stroke prevention are considered.

Abstract
Terminology for PFO tunnel sizing remains unstandardized. Device size selection for transcatheter PFO closure is highly variable. Tunnel width measurements may be a better descriptor of PFO size. Wire sizing may be a useful technique for assessment of PFO dimensions. PFO sizing strategies based on tunnel width need to be better studied.

Abstract
Ischemic stroke, which occurs following blockage of the blood supply to the brain, is a leading cause of death worldwide. Its main cause is atherosclerosis, a disease of the arteries characterized by the deposition of plaques of fatty material on the inner artery walls. Multiple proteins involved in the inflammation response have been identified as diagnosing biomarkers of ischemic stroke. One of these is lipoprotein-associated phospholipase A2 (Lp-PLA2), an enzyme that can hydrolyze circulating oxidized phospholipids, generating proinflammatory lysophosphatidylcholine and promoting the development of atherosclerosis. In the last two decades, a number of studies have revealed that both the concentration and the activity of Lp-PLA2 are independent biomarkers of ischemic stroke. The US Food and Drug Administration (FDA) has approved two tests to determine Lp-PLA2 mass and activity for predicting stroke. In this review, we summarize the biological properties of Lp-PLA2, the detection sensitivity and limitations of Lp-PLA2 measurement, the clinical significance and association of Lp-PLA2 in ischemic stroke, and the prospects of therapeutic inhibition of Lp-PLA2 as an intervention and treatment.

Abstract
Although seemingly benign, the presence of a patent foramen ovale (PFO) may play an important role in the pathophysiology of disease, specifically a paradoxical embolism leading to cryptogenic stroke. The European Society of Cardiology recently published guidelines detailing how PFOs are associated with paradoxical embolism and how they are diagnosed and managed. This review guides physicians in the diagnostic and referral process to a multidisciplinary team involved in PFO closure. It reviews the clinical trials comparing device closure with medical therapy and highlights the current NHS England commissioning process on PFO management. Finally, we give an overview of other conditions where PFO device closure may need to be considered.

Abstract
Background Patent foramen ovale (PFO) is a common anatomic variant associated with intermittent right-to-left shunting. Transcatheter PFO closure has been proposed to address multiple clinical conditions including stroke, transient ischemic attack, migraine, and decompression illness. Methods A systematic review was conducted using the GRADE approach to address 5 questions formulated by the Society for Cardiovascular Angiography and Interventions (SCAI) Guideline Panel in patient, intervention, comparator, outcome (PICO) format. Medical literature from January 2015 through May 2021 was searched. Extracted data underwent review and risk-of-bias assessment by 2 independent researchers. Pooled effect estimates were calculated. Certainty of evidence was determined for each query. Results Our search identified 2701 titles and abstracts, of which 30 met eligibility criteria and informed the technical review. Data were abstracted to address outcomes of PFO closure for patients with and without prior stroke, in comparison to antiplatelet therapy, in comparison to anticoagulation, and with various post-procedure antithrombotic regimens. Conclusion In appropriately selected patients with prior stroke, transcatheter PFO closure reduces the risk of recurrent stroke more than antiplatelet therapy alone. Evidence to support PFO closure is weaker regarding older patients, anticoagulation, thrombophilia, transient ischemic attack, migraine, and decompression illness. Data from this technical review will inform the SCAI Guideline for Transcatheter Patent Foramen Ovale Closure.

Abstract
This case report describes the 2‐dimensional transthoracic (2D‐TTE), 3‐dimensional transthoracic (3D‐TTE) and intracardiac echocardiographic (ICE) characterization of the fossa ovalis region in 2 horses. The first case was presented for poor performance and showed an anechoic zone in the interatrial septum on 2D‐TTE. Based on 3D‐TTE a deepened fossa ovalis could be identified and using ICE the presence of an interatrial shunt could be excluded. The second case was referred for a cardiac murmur and the presence of turbulent flow in and around the interatrial septum on 2D‐TTE color flow Doppler. The complementary use of 2D‐TTE, 3D‐TTE, and ICE allowed detailed characterization of a patent foramen ovale, with evidence of a left‐to‐right shunt in a dorsocranial to ventrocaudal direction with limited hemodynamic implications. These 2 cases underline the feasibility of 3D‐TTE and ICE in horses and especially show the added value of ICE in a clinical setting.

Abstract
Intravenous drug use (IVDU) is a growing public health crisis worldwide. A known complication of IVDU is right-sided infective endocarditis (RSIE) involving the tricuspid valve. As the tricuspid valve is burdened with infectious vegetations, it becomes a potential source of pulmonary and, very rarely, paradoxical systemic emboli. We report two patients with RSIE involving the tricuspid valve presenting with acute change in mental status. Subsequent imaging demonstrated embolisation to the brain in the setting of elevated right atrial pressures and the presence of a patent foramen ovale (PFO) with right-to-left shunting. We employed a strategy of percutaneous closure of PFO, to prevent further embolisation, as a successful bridge to definitive surgical management of RSIE. We emphasise that clinicians should evaluate for intracardiac shunting and pursue transesophageal echocardiography when encountering systemic emboli of unknown origin, particularly in patients with RSIE.

Abstract
The role of patent foramen ovale (PFO) in stroke was debated for decades. Randomized clinical trials (RCTs) have shown fewer recurrent events after PFO closure in patients with cryptogenic stroke (CS). However, in clinical practice, treating stroke patients with coexisting PFO raises some questions. This brief review summarizes current knowledge and challenges in handling stroke patients with PFO and identifies issues for future research. The rationale for PFO closure was initially based on the concept of paradoxical embolism from deep vein thrombosis (DVT). However, RCTs did not consider such details, limiting their impact from a pathophysiological perspective. Only a few studies explored the coexistence of PFO and DVT in CS with varying results. Consequently, the PFO itself might play a role as a prothrombotic structure. Transesophageal echocardiography thus appears most appropriate for PFO detection, while a large shunt size or an associated atrial septum aneurysm qualify for a high-risk PFO. For drug-based treatment alone, studies did not find a definite superiority of oral anticoagulation over antiplatelet therapy. Remarkably, drug-based treatment in addition to PFO closure was not standardized in RCTs. The available literature rarely considers patients with transient ischemic attack (TIA), over 60 years of age, and competing etiologies like atrial fibrillation. In summary, RCTs suggest efficacy for closure of high-risk PFO only in a small subgroup of stroke patients. However, research is also needed to reevaluate the pathophysiological concept of PFO-related stroke and establish strategies for older and TIA patients and those with competing risk factors or low-risk PFO.

Abstract
BACKGROUND Patent foramen ovale (PFO) is a common congenital cardiac abnormality. Risk of stroke increases perioperatively; however, the association of PFO with perioperative stroke risk remains unclear. We conducted a systematic review to inform the risk of perioperative stroke in patients with PFO undergoing surgery. METHODS EMBASE, MEDLINE, and Cochrane databases were searched from inception to January 2020. We described methods used for establishing PFO and perioperative stroke diagnosis. We conducted meta-analyses to obtain pooled estimates for risk of stroke in patients with and without PFO in different surgical populations. RESULTS Ten articles with a total of 20,858,011 patients met the eligibility criteria. Prevalence of PFO ranged from 0.06-1.4% based on ICD code diagnosis and 10.4-40.4% based on echocardiography diagnosis. Perioperative stroke was observed in 0-25% of patients with PFO, and 0-16.7% without PFO. Studies that use echocardiography to diagnose PFO found no association between PFO and perioperative stroke. Studies that used ICD codes, found strong association but were highly heterogenous. PFO was not associated with a risk of perioperative stroke in cardiac and transplant surgeries. While the adjusted odds ratios for stroke were substantial for orthopedic, general, genitourinary, neuro, and thoracic surgeries (with PFO status established based on ICD codes), data heterogeneity and quality of data create significant uncertainty. CONCLUSION In conclusion, PFO is likely a risk factor for perioperative stroke in select types of surgeries. However, this is based on a very low-quality evidence. Rigorous, prospective studies are needed to further investigate this relationship.

Abstract
A patent foramen ovale (PFO) is a frequent incidental finding during echocardiography in otherwise healthy children. In most healthy children with a diagnosis of isolated incidental PFO, no further follow-up or intervention is necessary. In some children, PFO is associated with certain clinical syndromes such as cryptogenic stroke, decompression sickness, migraine, and platypnea-orthodeoxia syndrome. This review discusses PFO anatomy, diagnostic imaging, PFO-associated clinical situations, management options, and the role of PFO in certain congenital heart disease. This review also highlights the current deficiency of pediatric data guiding management of these uncommon but important PFO-associated conditions. Future multicenter randomized controlled studies are necessary to guide the management of these unique and challenging PFO-associated conditions.

Abstract
Cryptogenic stroke (CS) represents one-third of all ischaemic strokes. Studies have shown approximately that half of patients with CS have concomitant patent foramen ovale (PFO), with clear data supporting paradoxical embolization as an aetiology of CS. This article is the first of a multi-part review and will detail the history of PFO closure and the clinical trials that have evaluated the efficacy of PFO device closure. Data favour PFO closure in CS for reducing stroke in appropriate patients and should be considered as a treatment modality.

Abstract
Arterial thrombotic events in younger patients without a readily apparent etiology present significant diagnostic and management challenges. We present a structured approach to diagnosis with consideration of common causes, including atherosclerosis and embolism, as well as uncommon causes, including medications and substances, vascular and anatomic abnormalities, systemic disorders, and thrombophilias. We highlight areas of management that have evolved within the past 5 years, including the use of dual-pathway inhibition in atherosclerotic disease, antithrombotic therapy selection in embolic stroke of undetermined source and left ventricular thrombus, the role of closure of patent foramen ovale for secondary stroke prevention, and the thrombotic potential of coronavirus disease 2019 infection and vaccination. We conclude with a representative case to illustrate the application of the diagnostic framework and discuss the importance of consideration of bleeding risk and patient preference in determining the appropriate management plan.

Abstract
Ischemic stroke is a leading cause of morbidity and mortality worldwide. Embolic stroke of undetermined source has been recently proposed to categorize nonlacunar ischemic strokes without confirmed etiology after adequate investigation with a likely embolic stroke mechanism. A strategy of empirical anticoagulation for embolic stroke of undetermined source patients is attractive but may only be beneficial in a select subset of patients. Strategies which would help identify the subset of embolic stroke of undetermined source patients most likely to have cardioembolic origin of stroke, and hence benefit from anticoagulation, are needed. This article will review current evidence which may be useful in the development of a risk stratification approach based on arrhythmia monitoring, cardiac imaging, and clinical risk stratification. This approach may be beneficial in clinical practice in improving patient outcomes and reducing stroke recurrence in this population; however, further work is required with active trials underway.

Abstract
A 59-year-old male with a history of gallbladder adenocarcinoma receiving chemotherapy and on therapeutic anticoagulation for portal vein thrombosis presented to the emergency department via ambulance after being found unresponsive and in cardiac arrest. Initial workup upon return of spontaneous circulation revealed a large right atrial mass, patent foramen ovale (PFO), and bilateral acute cortical infarctions. This constellation of findings were concerning for PFO-related paradoxical embolic strokes. Given the risk of recurrent paradoxical embolic events and the absolute contraindication to thrombolysis due to recent cerebral infarction, the decision was made to proceed with percutaneous vacuum-assisted thrombectomy using the AngioVac device. To prevent intraoperative thrombus propagation, PFO-closure was performed immediately prior to thrombectomy. Aspiration thrombectomy and PFO-closure were successful with complete thrombus removal and no intraoperative thrombus propagation. This case presents a minimally invasive and rapid treatment for a complex problem. An efficient and effective interdisciplinary team-based approach allowed the patient to resume cancer treatment relatively unabated.

Abstract
A patent foramen ovale (PFO) is an interatrial shunt, with a prevalence of 20-34% in the general population. While most people do not have secondary manifestations of a PFO, some reported sequelae include ischaemic stroke, migraine, platypnoea-orthodeoxia syndrome and decompression illness. Furthermore, in some cases, PFO closure should be considered for patients before neurosurgery and for patients with concomitant carcinoid syndrome. Recent trials support PFO closure for ischaemic stroke patients with high risk PFOs and absence of other identified stroke mechanisms. While PFOs can be associated with migraine with auras, with some patients reporting symptomatic improvement after closure, the evidence from randomised controlled trials is less clear in supporting the use of PFO closure for migraine treatment. PFO closure for other indications such as platypnoea-orthodeoxia syndrome, decompression illness and paradoxical embolism are based largely on case series with good clinical outcomes. PFO closure can be performed as a day surgical intervention with high procedural success and low risk of complications.

Abstract
Background Due to its low incidence and diverse manifestations, paradoxical embolism (PDE) is still under-reported and is not routinely considered in differential diagnoses. Concomitant acute myocardial infarction (AMI) and acute pulmonary embolism (PE) caused by PDE has rarely been reported.
Case presentation
A 45-year-old woman presented with acute chest pain and difficulty with breathing. Multiple imaging modules including ECG, echocardiography, emergency cardioangiogram (CAG), and CT angiography of the pulmonary arteries showed acute occlusion of the posterolateral artery and acute PE.
After coronary aspiration, no residual stenosis was observed. One month later, a bubble study showed inter-atrial communication via a patent foramen ovale (PFO). The AMI in this patient was finally attributed to PDE via the PFO. PFO closure was performed, and long-term anticoagulation was prescribed to prevent recurrent thromboembolic events. Conclusions PDE via PFO is a rare etiology of AMI, especially in patients with concomitant AMI and PE. Clinicians should be vigilant of this possibility and close the inter-atrial channel for secondary prevention.

Abstract
BACKGROUND Pulmonary embolism (PE) and acute ischemic stroke (AIS) are common disorders with high morbidity and mortality, rarely presenting simultaneously. There is a paucity of data regarding the management of this uncommon presentation. The treatment of these two entities is complex in the acute phase due to the concomitant need for thrombolysis in AIS and anticoagulation for PE. METHODS We retrospectively reviewed confirmed ischemic stroke cases to identify patients presented with simultaneous PE from June 2018 to May 2019. Additionally, a literature review was performed. Two reviewers assessed the manuscripts' quality, and relevant data regarding clinical course and management was extracted. RESULTS We reviewed 439 patient charts, identifying two cases of concomitant AIS and PE. Additionally, twelve articles (n = 15 subjects) fulfilled our literature review criteria for a total of 17 cases, including ours. Intravenous anticoagulation (70.5%) was the most frequent intervention targeting both disorders. Therapies such as intravenous thrombolysis (23.53% (n = 4)) and mechanical thrombectomy (23.53% (n = 4)) were specific in AIS. Catheter-directed thrombolysis (5.88%) was used for PE. Clinical outcomes were favorable (asymptomatic or mild disable symptoms) in 47.05% (N = 8) of patients, while 41.17% had poor outcomes (severe disable symptoms or death). CONCLUSIONS AIS and PE stand for a challenge when they present simultaneously. The evaluation of risks and benefits of therapies such as intravenous thrombolysis, mechanical thrombectomy, and catheter-directed-thrombolysis in the clinical context is essential. According to our review, the ischemic stroke burden guides systemic anticoagulation decisions over interventional procedures when the hemodynamic status remains unaffected.

Abstract
A 52-year-old woman with cystic fibrosis presented to the emergency department with expressive aphasia and right-sided hemiparesis. CT scan of the brain revealed a left middle cerebral artery territory infarct. A diagnosis of cerebral paradoxical embolisation associated with patent foramen ovale and a history of deep venous thrombosis was made. The patient underwent endovascular thrombectomy and percutaneous closure of patent foramen ovale. Current literature, including five published case reports, pertaining to the subject is discussed. The unique aspects of the case are highlighted, including the particular risk of cerebral paradoxical embolisation in patients with cystic fibrosis. The result of this case report, in context to previously reported literature, suggests that clinicians should be aware of paradoxical embolisation in patients with cystic fibrosis via an intracardiac shunt, particularly with implanted vascular access devices and a history of deep venous thrombosis.
