Incidental diagnosis of a large cardiac thrombus swinging through an interatrial communication in a COVID-19 patient: Case report and literature review. Ann Med Surg (Lond) 2021; 71:102967. [PMID: 34691408 PMCID: PMC8524807 DOI: 10.1016/j.amsu.2021.102967] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 10/14/2021] [Accepted: 10/15/2021] [Indexed: 12/13/2022] Open
Abstract
Introduction The hypercoagulability state induced by COVID-19 has been well established and various forms of subsequent thromboembolic events have been reported throughout literature including multiple cases of intracardiac thrombi, four of which in our center alone, this case being the fifth. Case report We report the case of a 38-year-old male with no prior cardiovascular history who -subsequently to a COVID-19 infection-developped a right atrial thrombosis associated to a pulmonary embolism, and in whom cardiography revealed an interatrial communication. Management relied upon curative doses of low molecular weight heparin (LMWH) with favourable outcome. Discussion In our discussion, we lay out the various physiopathological mechanisms incriminated throughout literature in the genesis of a hypercoagulability state distinctive of COVID-19, before highlighting the incidence of an interatrial communication (whether a Potent Foramen Ovale or Atrial Septal Defect) discovered in patients with COVID-19, and the potential paradoxical embolization risks they imply as well as reported cases. A mention of hemostatic parameters monitored was also warranted. Finally we discuss the guidelines in terms of prophylactic and therapeutic anticoagulation in hospitalized patients before discussing cardiac thrombosis's therapeutic options. Conclusion Our case highlights various key points which could change the prognosis of COVID-19 patients, whether related to the underdiagnosis of interatrial abnormalities or with regards to the diagnosis to thromboembolic events, but also the indisputable place of anticoagulation in COVID-19 management. Thromboembolic events complicating COVID-19 have been well described and are attributed to a hypercoagulability state distinctive of COVID-19. A pre-existing Potent Foramen Ovale (PFO) or Atrial septal Defect (ASD) in COVID-19 patients is unknown as only a handful of studies covered the subject. The association of a cardiac thrombosis with a pulmonary embolism and interatrial communication exposes patients to risks of paradoxical embolization and subsequent arterial thrombotic events. Prophylactic and curatrive anticoagulation is unrefutably a key pillar in the management of COVID-19.

Abstract
PURPOSE OF REVIEW The present review discusses in-depth about neurological complications following acute venous thromboembolism (VTE). RECENT FINDINGS Intracranial hemorrhage, acute ischemic cerebrovascular events, and VTE in brain tumors are described as central nervous system (CNS) complications of PE, while peripheral neuropathy and neuropathic pain are reported as peripheral nervous system (PNS) sequelae of PE. Syncope and seizure are illustrated as atypical neurological presentations of PE. Mounting evidence suggests higher risk of venous thromboembolism (VTE) in patients with neurological diseases, but data on reverse, i.e., neurological sequelae following VTE, is underexplored. The present review is an attempt to explore some of the latter issues categorized into CNS, PNS, and atypical complications following VTE.

Abstract
OBJECTIVE To determine if a clinical presentation indistinguishable from migraine can occur due to an underlying condition or pathology, that is, "symptomatic migraine." BACKGROUND It is currently not clear whether migraine truly can be caused by an underlying condition or pathology. Characterization of the etiology and clinical features of possible symptomatic migraine is of significant clinical importance and further may help elucidate the pathophysiology of migraine. METHODS We devised operational diagnostic criteria for "symptomatic migraine" and "possible symptomatic migraine" requiring strong evidence for a causal relation between underlying cause and migraine symptoms adhering strictly to diagnostic criteria. PubMed was searched for case reports of symptomatic migraine from inception to March 2020. Only articles published in English or German were included. No restrictions were placed on study design. Relevant references in the articles were also included. Papers were systematically reviewed by two independent reviewers for detailed clinical features of migraine as well as the proposed underlying conditions and the effects of treatment of these conditions. RESULTS Our search retrieved 1726 items. After screening, 109 papers comprising 504 cases were reviewed in detail. Eleven patients with migraine with aura (MWA) fulfilled our working criteria for symptomatic migraine, and 39 patients fulfilled our criteria for possible symptomatic migraine. The most common etiologies of symptomatic migraine were arteriovenous malformations, carotid stenosis, dissection or aneurysm, brain infarctions, meningioma, and various intra-axial tumors. CONCLUSIONS Symptomatic MWA, indistinguishable from idiopathic MWA, may occur due to cortical lesions or microembolization. We found no clear evidence supporting the existence of symptomatic migraine without aura although we did identify possible cases. Our findings are limited by the available literature, and we suggest that prospective studies are needed.

Abstract
Patent foramen ovale (PFO) is a common congenital atrial septal defect with an incidence of 15–35% in the adult population. The development of the interatrial septum is a process that begins in the fourth gestational week and is completed only after birth. During intrauterine life, the foramen ovale allows the passage of highly oxygenated blood from the right to the left atrium and into the systemic arteries, thus bypassing the pulmonary circulation. In 75% of the general population, the foramen ovale closes after birth, and only an oval depression, called fossa ovalis, remains on the right side of the interatrial septum. Patent foramen ovale can be associated with various clinically important conditions, including migraine and stroke, or decompression illness in divers. The aim of this review is to summarize the PFO developmental and anatomical features and to discuss the clinical risks associated with this atrial septal defect in adults.

Abstract
OBJECTIVE The management recommendations for patent foramen ovale (PFO) closure in cryptogenic stroke are rapidly evolving. The data has expanded recently with four major trials demonstrating superiority of percutaneous device closure over medical management in preventing cryptogenic stroke recurrence. This paper aims to review the current literature for referring physicians who may encounter patients with patent foramen ovale before referring these patients to stroke specialists and/or interventional cardiologists. METHOD For this Narrative review, we conducted a broad literature search with expert selection of relevant data. Our search included a review of the currently available trials, guideline statements, position papers, cost-effectiveness of device closure data, as well as the impact of device closure on quality of life. RESULTS Most European societies are now in favor of evaluating all patients aged 60 years or younger with recent cryptogenic stroke in the setting of a PFO after careful consideration of the patient's echocardiographic and clinical risk factors. On the other hand, American societies, except for the American Academy of Neurology, have not yet passed official updated recommendations. CONCLUSION PFO closure can be considered for the prevention of recurrent cryptogenic stroke in patients aged ≤60 years after a thorough evaluation and discussion about benefits and potential risks (including but not limited to atrial fibrillation) of the procedure. Accumulating evidence supports prognostic, quality of life, and economic benefit from percutaneous PFO closure with newer generation closure devices in the right subset of patients. HIGHLIGHTS Data from 4 major trials (RESPECT, CLOSE, DEFENSE-PFO, REDUCE) demonstrates the superiority of PFO closure over medical management alone in preventing cryptogenic stroke recurrence. Trials investigated mostly patients ≤60 years old, and therefore results may not be generalizable to the entire population. Further randomized trials evaluating the safety and efficacy of PFO closure in patients older than 60 years are warranted.Atrial fibrillation is one of the most common "occult" causes of cryptogenic stroke and should be excluded by ambulatory electrocardiographic monitoring. It is important to also rule out other causes of stroke, including hypercoagulable states, atherosclerotic lesions, other cardioembolic sources, and arterial dissection.Complications of PFO procedure include new-onset AF, development of scar tissue, risk of aortic root dilation and subsequent erosions, and potential thrombi formation on the device.PFO closure with medical therapy is more cost-effective than medical therapy alone.Patients who underwent PFO closure had lower rates of depression, anxiety, and stress compared to those who did undergo closure.Development of the RoPE score has helped clinicians identify patients with cryptogenic stroke and PFO who might be a candidate for PFO closure. A score of 7, 8, and 9-10 corresponds to a causal risk of 72%, 84%, and 88%, respectively, and defines a subset of patients who may benefit from PFO closure.Current guidelines recommend determining the need for PFO closure on a case-by-case basis, depending on risk factors, in patients age 60 or less with recent cryptogenic stroke in the setting of PFO.

Abstract
Patent foram ovale (PFO) is the most common anatomical cause of an interarterial shunt. It is usually asymptomatic but may cause paradoxical embolism and is a risk factor for non-lacunar cryptogenic cerebral ischemia in young adults. Although the first clinical trials did not show a significant superiority of PFO closure in the secondary prevention of cerebral ischemia as compared with standard antithrombotic treatment, six subsequent randomized clinical trials (CLOSURE I, PC Trial, RESPECT, CLOSE, REDUCE, and DEFENSE-PFO) performed in a sample of cryptogenic stroke in patients aged 60 years or younger provided evidence of a significant reduction of recurrent cerebral ischemia after percutaneous PFO closure. However, the use of percutaneous PFO closure cannot be generalized to the entire population of patients with cerebral ischemia and PFO, but it is indicated in highly selected patients with non-lacunar cryptogenic cerebral infarction with a large right-to-left shunt, an atrial septal aneurysm and no evidence of atrial fibrillation, as well as in association with antithrombotic treatment for an optimal secondary prevention of cerebral ischemia.

Abstract
Background and objective Eosinophils are associated with thromboembolic events. Since eosinophils are eliminated in the pulmonary vasculature, right-to-left shunt (RLS) through patent foramen ovale may increase eosinophils in the peripheral blood. In this report, we evaluated the eosinophils of patients with regard to the presence of RLS and its quantity. Patients and methods In this retrospective observational study, we analyzed the complete blood cell count (CBC) of patients with RLS (n=47) and without RLS (n=31) diagnosed by contrast echocardiography (CE). RLS was identified as mild (5-10 bubbles) and moderate shunt (10-25 bubbles). Results Age and CBC were not significantly different between the groups, with the exception of eosinophils. Patients with RLS had higher eosinophils percentage compared to patients without RLS (3.1 ±1.5 vs. 1.7 ±0.7, p=0.001). Additionally, eosinophils percentage was significantly higher in the mild RLS group (2.4 ±0.9 vs. 1.7 ±0.7, p=0.016) and the moderate RLS group (4.3 ±1.6 vs. 1.7 ±0.7, p=0.001) compared to normal subjects. Also, it was significantly higher in the moderate RLS group compared to the mild group (4.3 ±1.6 vs. 2.4 ±0.9, p=0.001). Conclusions Eosinophils percentage was higher in patients with mild and moderate RLS compared to normal individuals. Moreover, the eosinophil rate was higher in patients with moderate RLS than in patients with mild RLS.

Prevalence of patent foramen ovale in the Greek population is high and impacts on the interpretation of the risk of paradoxical embolism (RoPE) score. Ther Adv Neurol Disord 2021; 13:1756286420964673. [PMID: 33425013 PMCID: PMC7758802 DOI: 10.1177/1756286420964673] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2020] [Accepted: 09/14/2020] [Indexed: 11/16/2022] Open
Abstract
Background: The risk of paradoxical embolism (RoPE) score calculates the probability that
patent foramen ovale (PFO) is causally related to stroke (PFO attributable
fraction, PFOAF), based on PFO prevalence in patients with cryptogenic
stroke (CS) compared with that in the general population. The latter has
been estimated at 25%; however, PFO prevalence in nonselected populations
varies widely. Methods: Since PFO prevalence in Greece remains unknown, we evaluated it and we
calculated PFOAF stratified by RoPE score in a cohort of patients with
CS ⩽55 years old. PFO was detected according to the international consensus
transcranial Doppler (TCD) criteria in 124 healthy subjects (H), in 102
patients with CS, and in 56 patients with stroke of known cause (nonCS).
Each subject underwent unilateral middle cerebral artery recording after
infusion of agitated saline, at rest, and after a controlled Valsalva
maneuver. We characterized PFO as large (>20 microbubbles or curtain),
moderate (11–20), and small (⩽10). Results: PFO was detected in 42.7% of H, 49% of CS, and 25% of nonCS
(p = 0.013). Large PFOs were numerically higher in CS
[28.4% (29/102)] compared with H [19.3% (24/124); p = 0.1]
and to nonCS [7.1% (4/56), p = 0.04]. The median RoPE score
in patients with CS and PFO was seven. Even patients with very high RoPE
score (9–10) had moderate PFOAF (57%). For any individual stratum up to RopE
score 8, PFOAF was <33%. Conclusions: PFO prevalence in the Greek population is much higher than the widely
accepted 25%. PFO may be the cause of stroke in one out of nine Greek
patients with CS. Among Greek CS patients who harbor a PFO, the latter is
causal in one out of five. The established RoPE score cutoff of ⩾7 for
having a probable PFO-associated stroke may overestimate the probability in
patients deriving from populations with high PFO prevalence.

Abstract
The posterior cranial fossa with its complex anatomy houses key pathways regulating consciousness, autonomic functions, motor and sensory pathways, and cerebellar centers regulating balance and gait. The most common posterior fossa pathologies for which neurosurgical intervention may be necessary include cerebellopontine angle tumors, aneurysms, and metastatic lesions. The posterior cranial fossa can be accessed from variations of the supine, lateral, park-bench, prone, and sitting positions. Notable complications from positioning include venous air embolism, paradoxic air embolism, tension pneumocephalus, nerve injuries, quadriplegia, and macroglossia. An interdisciplinary approach with careful planning, discussion, and clinical management contributes to improved outcomes and reduced complications.

Abstract
Background: Thrombi identified on echocardiography at the time of straddling a patent foramen ovale (PFO) constitute a medical emergency with an associated imminent risk of death. Ischemic stroke (IS) and myocardial infarction (MI) occurring in patients with a thrombus straddling a PFO (TSPFO) may be associated with increased risk of in-hospital death. Variables associated with increased risk of death in women and men may be different. We will perform a systematic review of case reports and cases series of patients with a TSPFO to assess if IS and MI are associated with increased risk of in-hospital death and we will further stratify analyses by sex. Methods: This systematic review will include all case reports and case series of adult patients (18-year-old or older) with echocardiographic or pathological (e.g. at autopsy for older reports) evidence of a TSPFO published between inception and June 30, 2020, in any language. We will search in PubMed and Embase databases. Two reviewers will independently screen titles and abstracts, retrieve full texts, and extract the data in a predesigned form. We will apply a multivariable logistic regression analysis to estimate the association of IS and MI with in-hospital mortality. We will stratify analyses by sex. Discussion: IS and MI in patients with TSPFO could potentially be associated with worse outcomes if they are not timely identified or left untreated. Both acute IS and MI require specific treatment (e.g. thrombolysis, primary coronary intervention, or mechanical thrombectomy) that may be influenced by the therapy instituted for the TSPFO. Knowing the incidence of acute IS and MI among patients diagnosed with TSPFO and whether they are associated with an increased risk of death would help to improve the management of this medical emergency.

Knowing the incidence of acute IS and MI among patients diagnosed with TSPFO and whether they are associated with an increased risk of death would help to improve the management of this medical emergency.

Association between Migraine and Cryptogenic Ischemic Stroke in Young Adults. Ann Neurol 2020; 89:242-253. [PMID: 33078475 DOI: 10.1002/ana.25937] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Revised: 08/26/2020] [Accepted: 10/11/2020] [Indexed: 01/23/2023]
Abstract
OBJECTIVE To assess the association between migraine and cryptogenic ischemic stroke (CIS) in young adults, with subgroup analyses stratified by sex and presence of patent foramen ovale (PFO). METHODS We prospectively enrolled 347 consecutive patients aged 18 to 49 years with a recent CIS and 347 age- and sex-matched (±5 years) stroke-free controls. Any migraine and migraine with (MA) and migraine without aura (MO) were identified by a screener, which we validated against a headache neurologist. We used conditional logistic regression adjusting for age, education, hypertension, diabetes, waist-to-hip ratio, physical inactivity, current smoking, heavy drinking, and oral estrogen use to assess independent association between migraine and CIS. The effect of PFO on the association between migraine and CIS was analyzed with logistic regression in a subgroup investigated with transcranial Doppler bubble screen. RESULTS The screener performance was excellent (Cohen kappa > 0.75) in patients and controls. Compared with nonmigraineurs, any migraine (odds ratio [OR] = 2.48, 95% confidence interval [CI] = 1.63-3.76) and MA (OR = 3.50, 95% CI = 2.19-5.61) were associated with CIS, whereas MO was not. The association emerged in both women (OR = 2.97 for any migraine, 95% CI = 1.61-5.47; OR = 4.32 for MA, 95% CI = 2.16-8.65) and men (OR = 2.47 for any migraine, 95% CI = 1.32-4.61; OR = 3.61 for MA, 95% CI = 1.75-7.45). Specifically for MA, the association with CIS remained significant irrespective of PFO. MA prevalence increased with increasing magnitude of the right-to-left shunt in patients with PFO. INTERPRETATION MA has a strong association with CIS in young patients, independent of vascular risk factors and presence of PFO. ANN NEUROL 2021;89:242-253.

Systemic thromboemboli in patients with Covid-19 may result from paradoxical embolization. Thromb Res 2020; 196:206-208.

Abstract
There is increasing evidence that Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection causes an unusual pneumonia and a pro-coagulant state that significantly increases the risk of arterial and venous thromboembolism. We hypothesize that, in select patients, some complications of COVID-19 may be due to right-to-left (RTL) shunt. Shunt may be intra-pulmonary, or extra-pulmonary, and can cause paradoxical embolization, hypoxia and platypnoea orthodeoxia. Saline microbubble contrast echocardiography is a minimally invasive, inexpensive, bedside test that can detect, quantify, and define the anatomical substrate of intra-pulmonary and intra-cardiac shunts. The prevalence of patent foramen ovale (PFO) in the general population is high (20–30%) but is even higher in patients who have a stroke (50%). Thus, the striking absence of data on patients with PFO who develop COVID-19 suggests that this is being under-diagnosed. This may be because physicians and sonographers currently feel that screening for shunt is unnecessary. This could be an unintended consequence of guidance from several specialist societies to defer procedures to close PFO until after the pandemic. This may be counterproductive. Patients with shunt may be at particularly high risk of complications from COVID-19 and interventions to minimise RTL shunt could prevent paradoxical embolization and improve hypoxia in select high risk patients with COVID-19. There is significant variation in the neurological sequelae of Coronavirus 2019 (COVID-19). Patent foramen ovale (PFO) is present in 25-30% of the general population. Inter-atrial defects may account for some of the heterogeneity of COVID-19 Echocardiography with microbubble contrast should be used to screen for shunt in patients with COVID-19 Closure of PFO may prevent paradoxical embolism and improve hypoxia in select high risk patients with COVID-19

J Neuroimaging 2020; 31:165-170. [PMID: 32896963 DOI: 10.1111/jon.12783] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 07/29/2020] [Accepted: 08/22/2020] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND AND PURPOSE The identification of high-risk patent foramen ovale (PFO) is important for selecting suitable patients for PFO closure to prevent recurrent stroke in those with cryptogenic stroke. We aimed to evaluate the predictability of transcranial Doppler (TCD) in diagnosing high-risk PFO compared with that of transesophageal echocardiography (TEE), which is not feasible for some stroke patients. METHODS We retrospectively reviewed the data of 461 cryptogenic stroke patients who underwent TEE and TCD for PFO evaluation. High-risk PFO on TEE was defined as PFO with atrial septal aneurysm (phasic septal excursion ≥10 mm) or large PFO (≥2 mm). Spencer grading of right-to-left shunt was used to classify the amount of shunt on TCD. RESULTS PFO on TEE was observed for 242 (52.5%) patients, and high-risk PFO was detected for 123 (26.7%) patients. However, PFO on TCD was observed for 336 (72.9%) patients. Among patients with significant shunt (Spencer grade III or higher) who underwent TCD after Valsalva maneuver (VM), 60.0% of patients had high-risk PFO. However, only 5.3% of patients had high-risk PFO among those without significant shunt. Receiver operating characteristic curves showed that significant shunt after VM had higher predictability (AUC = .876, 95% CI: .843-.905) for detecting the high-risk PFO compared with the predictability based on significant shunt at rest (AUC = .718, 95% CI: .674-.759). (P<.0001 for the differences between two AUCs). CONCLUSIONS TCD is a good screening tool for evaluating high-risk PFO. VM is important for the evaluation of PFO. Patients with minimal or no shunt on TCD after VM are unlikely to have high-risk PFO.
