Atrial Cardiopathy and Likely Pathogenic Patent Foramen Ovale in Embolic Stroke of Undetermined Source.

Atrial Cardiopathy and Likely Pathogenic Patent Foramen Ovale in Embolic Stroke of Undetermined Source. Thromb Haemost. 2020 Sep 02;: Authors: Leventis IA, Sagris D, Strambo D, Perlepe K, Sirimarco G, Nannoni S, Korompoki E, Manios E, Makaritsis K, Vemmos K, Michel P, Ntaios G Abstract BACKGROUND:  Atrial cardiopathy and likely pathogenic patent foramen ovale (PFO) are two potential embolic sources in patients with embolic stroke of undetermined source (ESUS). The relationship between these two mechanisms among ESUS patients remains unclear. METHODS:  Atrial cardiopathy was defined as increased left atrial diameter index (> 23 mm/m2) or left atrial volume index (> 34 mL/m2), or PR prolongation (≥ 200 ms), or presence of supraventricular extrasystoles in the electrocardiograms performed during hospitalization for the index stoke. The presence of PFO was assessed by transthoracic echocardiography with microbubble test or by transesophageal echocardiography. The presence of PFO was considered as likely pathogenic if the Risk of Paradoxical Embolism score was 7 to 10. RESULTS:  Among 367 ESUS patients with available information about the presence of PFO and the presence of atrial cardiopathy (median age: 61 years, 40.6% women), likely pathogenic PFO was diagnosed in 62 (16.9%) and atrial cardiopathy in 122 (33.2%). Only 4 patients (1.1%) had both likely pathogenic PFO and atrial cardiopathy. The prevalen...

AbstractPatent foramen ovale (PFO) is a potential conduit for paradoxical embolization to the systemic atrial circulation of a thrombus originating in the venous system. In a selected group of subjects, the prevalence of deep vein thrombosis (DVT) was assessed. Subjects were identified if they underwent magnetic resonance venography (MRV) pelvis and lower extremity doppler (LE-VDU) for assessment of DVT with PFO. The primary outcome measure was to report the number of patients with paradoxical embolization as their suspected etiology of stroke due to the presence of DVT, which then will be considered as determined stroke. ...

Conclusions: This is the first reported case of intraoperative paradoxical embolism in the setting of RCC with cavoatrial extension and PFO. The presence of PFO may be a risk factor for severe cerebrovascular complications in the surgical management of RCC with venous involvement.

Conclusion: In patients with CS and PFO, the likelihood of prior stroke is associated with both, PFO-related and PFO-unrelated factors.

Abstract Cardiogenic stroke (CS), characteristic causes of which include atrial fibrillation (AF) and right-to-left shunting due to a patent foramen ovale (PFO), has a well-known tendency to be associated with a more extensive ischemic area. This may result in severe neurological damage, and require strict life-long antithrombotic therapy. However, the fact that some patients have problems complying with the requirement for extended oral antithrombotic treatment has motivated the development of alternative approaches for stroke prevention. Heart structures such as the left atrial appendage (LAA) and PFO are potent...

We present a case report of a patient with a pulmonary embolus placed on venoarterial extracorporeal membrane oxygenation who developed venous cannula migration through an undiagnosed patent foramen ovale causing an ischemic stroke due to a thrombus and requiring thrombectomy and device closure of the atrial defect.

Conclusion: VTE can be detected in patients with CS linked to PFO. While –based on the presented literature–routine screening for VTE in patients with CS linked to PFO does not appear justified, history taking, and clinical exam should consider concomitant VTE. Whenever clinically suspected, the threshold to trigger ancillary testing for VTE should be low. Among patients with an acute PE and PFO, vigilance for new neurologic deficits should be increased, with a low threshold for brain imaging.

Rationale: Patent foramen ovale (PFO) is not considered to be the main cause of stroke and is classified as the infarction of undetermined cause. The relationship between PFO and cerebral embolism is still unclear and cerebral embolism accompanied with coronary artery embolization in PFO patient is rare. In this case, we reported a patient with PFO suffered acute cerebral and myocardial infarction simultaneously, and analyzed the source of emboli and potential pathogenesis. Patient concerns: A 53-year-old female presented with chief complaints of intermittent palpitations and chest tightness for 6 years, aggravated fo...

Paradoxical embolism refers to a potential condition in which an embolus arising from a venous source crosses into the systemic circulation through a right-to-left cardiac shunt causing an arterial embolism.A 39-year-old woman carrier of a central venous catheter (CVC) without evident risk factors for stroke, developed an acute right homonymous hemianopia during hemodialysis. On neuroimaging, an infarct in the territory of the left posterior cerebral artery was demonstrated. Transesophageal echocardiography revealed a patent foramen ovale (PFO) and a large fluctuating thrombus in the right atrium on the tip of the CVC, thu...

Abstract OBJECTIVE/BACKGROUND: Migraine is associated with ischemic stroke. Women are 3-fold as likely as men to have migraine, and high estrogen states increase the risk of migraine with aura (MWA), venous thromboembolism (VTE), and of stroke. We review the epidemiological and mechanistic evidence of the migraine-stroke relationship and its risk factors, with a focus on women and conditions that exclusively or predominantly affect them.  METHODS: We performed a search of MEDLINE/PubMed database, then a narrative review of the epidemiological evidence of the migraine-stroke relationship as...

Rationale: Paradoxical embolism (PE) is an important cause of cryptogenic stroke, particularly in young patients, which usually have a relation with an unexpected route in circulation. Here we report a rare case of cryptogenic stroke carried 2 uncommon malformations. Patient concerns: A 48-year-old female experienced double neurological events in just 2 months. Diagnosis: Patent foramen ovale was diagnosed with transesophageal echocardiography and successfully occluded in the first admission due to stroke. In the second admission, chest tomographic angiography found a chordae shadow in the right middle lobe, was th...
