Department of Internal Medicine, State University of New York: Downstate Medical Center, Brooklyn, New York, United States-11203.

Patent foramen ovale (PFO) is a common clinical entity that is encountered in 20-34% of the general population. In most individuals, this anatomical variation is asymptomatic and goes undetected throughout their lives or is only incidentally discovered on cardiac investigations. In situations when the conduit is large enough and when the right atrial pressure exceeds the left atrial pressure, right to left interatrial flow may occur in these individuals. Read More

Eustachian valve, interatrial shunt, and paradoxical embolism.

Echocardiography 2020 May 19. Epub 2020 May 19.

Division of Cardiology, University of Texas Medical Branch, Galveston, TX, USA.

Randomized clinical trials demonstrate that percutaneous closure of the patent oval foramen is a safe and effective treatment for secondary prevention of cryptogenic stroke in selected patients. The Eustachian valve is generally considered an incidental finding without any significant pathophysiological consequences in adults. However, a persistent Eustachian valve, particularly a prominent one, is significantly more prevalent in patients with patent oval foramen and cryptogenic stroke, and is associated with adverse outcomes following percutaneous closure.

Epidemiology of Patent Foramen Ovale in General Population and in Stroke Patients: A Narrative Review.

Front Neurol 2020 28;11:281. Epub 2020 Apr 28.

Second Department of Neurology, AHEPA University Hospital, Aristotle University of Thessaloniki, Thessaloniki, Greece.

Percutaneous closure of patent foramen ovale (PFO) in selected patients with cryptogenic cerebrovascular ischemic events (CEs) decreases the risk of recurrent stroke; however, optimal patient selection criteria are still under investigation. Candidates for PFO closure are usually selected from the pool of CE patients with a high risk of Paradoxical Embolism (RoPE) score. The RoPE score calculates the probability that PFO is causally related to stroke, based on PFO prevalence in patients with CE compared with that in healthy subjects. Read More

The Closure of Patent Foramen Ovale in Preventing Subsequent Neurological Events: A Bayesian Network Meta-Analysis to Identify the Best Device.

Cerebrovasc Dis 2020 14;49(2):124-134. Epub 2020 Apr 14.

Department of Neurology, San Bortolo Hospital, Vicenza, Italy.

Background: Randomized-controlled trials (RCTs) reported a finding on the safety and efficacy of percutaneous patent foramen ovale (PFO) closure to prevent stroke recurrence. It showed that the Amplatzer (AMP) device appears to be superior to medical therapy (MT) in preventing strokes and episodes of atrial fibrillation (AF), than other devices. We performed a network meta-analysis (NMA) to evaluate the closure of PFO in preventing subsequent neurological events while investigating the results obtained by specific devices. Read More

Clinical conundrum: concomitant high-risk pulmonary embolism and acute ischemic stroke.

Emerg Radiol 2020 Mar 24. Epub 2020 Mar 24.

Department of Thoracic Medicine and Surgery, Lewis Katz School Of Medicine, Temple University Hospital, Philadelphia, PA, USA.

High-risk PE can be complicated by the presence of a patent foramen ovale (PFO), which can lead to paradoxical systemic embolization, including cerebral embolism ultimately leading to acute ischemic stroke (AIS). Acute management is challenging given the competing benefits and risks of systemic thrombolysis. Herein, we aim to provide a review of clinical presentations, diagnostic findings, and treatment and outcome from the available literature, with the hopes of providing insight into treatment options.

[Cerebral embolism as an atypical presentation of May Thurner syndrome].

Medicina (B Aires) 2019 ;79(6):502-505

Servicio de Diagnóstico por Imágenes, Hospital Italiano de Buenos Aires, Argentina.

May-Thurner syndrome is an anatomic abnormality that predisposes patients to increase risk of paradoxical embolism and stroke. It consists of chronic compression of the left common iliac vein by the overlying right common iliac artery and lumbar spine. This may lead to deep venous thrombosis and paradoxical embolism that could provoke cerebral ischemia in patients with a cardiac shunt from right-to-left. Read More

Cardiac arrest in a healthy child due to paradoxical embolus across a previously unrecognised sinus venosus defect.

BMJ Case Rep 2019 Dec 5;12(12). Epub 2019 Dec 5.

Herma Heart Institute, Children's Wisconsin, Milwaukee, WI, USA.

A previously healthy, preadolescent female suffered an unwitnessed cardiac arrest with prompt return of circulation following bystander initiated resuscitation. Workup demonstrated the cause of her cardiac arrest to be distal left anterior descending coronary artery occlusion with small apical left ventricular transmural myocardial infarction, from a paradoxical embolus traversing a previously undiagnosed large sinus venous defect. This case demonstrates the value of cardiac magnetic resonance imaging may bring to the diagnosis of the pathophysiology leading to cardiac arrest. Read More

Association of the incidence of venous air embolism on coronary computed tomography angiography with the intravenous access route preparation process.

Medicine (Baltimore) 2019 Nov;98(45):e17940

Department of Diagnostic Radiology, Tohoku University Hospital, Sendai.

Venous air embolism (VAE) can be observed in the right heart system on contrast-enhanced computed tomography (CT), following injection of contrast media with a power injector system. Although most VAEs are mostly asymptomatic, they may result in paradoxical air embolism (PAE).To evaluate whether the incidence of VAE on coronary CT angiography is associated with the process of preparation of the intravenous access route.

Two cases of pericardial tamponade due to nitinol wire fracture of a gore septal occluder.

Catheter Cardiovasc Interv 2019 Nov 7. Epub 2019 Nov 7.

Division of Cardiology, Department of Medicine, University of California, Los Angeles, Los Angeles, California.

Percutaneous patent foramen ovale (PFO) closure is recommended for secondary prevention of paradoxical embolism through a PFO. In the United States, two Food and Drug Administration-approved PFO closure devices are currently available, and the choice depends on operator preference and PFO anatomy. Although these devices are easy to implant, there are several potential complications. Read More

An Elderly Man with Syncope, Hypoxia, and Confusion: A Case Report and Review of Literature.

Cureus 2019 Sep 4;11(9):e5567. Epub 2019 Sep 4.

Nephrology / Internal Medicine, Lynchburg General Hospital, Lynchburg, USA.

Controversies exist regarding the treatment of acute massive pulmonary embolism (PE) with anticoagulation alone or with thrombolytic therapy. Paradoxical embolism in the presence of a patent foramen ovale (PFO) is a rare but well-known entity and should always be looked for in case of a PE associated with systemic thromboembolism. We report a case of acute sub-massive PE treated with thrombolytic therapy in an elderly gentleman who had a paradoxical embolism and ischemic stroke as a result of a clot traversing through a PFO.

Antithrombotic Treatment in Cryptogenic Stroke Patients With Patent Foramen Ovale: Systematic Review and Meta-Analysis.

Stroke 2019 11 24;50(11):3135-3140. Epub 2019 Sep 24.

From the Department of Internal Medicine, Faculty of Medicine, School of Health Sciences, University of Thessaly, Larissa, Greece (D.S., K. Perlepe, K.M., G.N.).

Background and Purpose- It is unclear whether treatment with anticoagulants or antiplatelets is the optimal strategy in patients with stroke or transient ischemic attack of undetermined cause and patent foramen ovale that is not percutaneously closed. We aimed to perform a systematic review and meta-analysis of randomized controlled trials to compare anticoagulant or antiplatelet treatment in this population. Methods- We searched PubMed until July 16, 2019 for trials comparing anticoagulants and antiplatelet treatment in patients with stroke/transient ischemic attack and medically treated patent foramen ovale using the terms: "cryptogenic or embolic stroke of undetermined source" and "stroke or cerebrovascular accident or transient ischemic attack" and "patent foramen ovale or patent foramen ovale or paradoxical embolism" and "trial or study" and "antithrombotic or anticoagulant or antiplatelet.

Cerebrovascular accidents in Ebstein's anomaly.

Congenit Heart Dis 2019 Nov 23;14(6):1157-1165. Epub 2019 Sep 23.

Department of Cardiovascular Diseases, Mayo Clinic, Rochester, Minnesota.

Introduction: Mechanisms and risk factors for cerebrovascular accidents (CVAs) in Ebstein's anomaly (EA) are not well understood; hence, we aimed to clarify these in a large cohort of EA patients.

Methods: Patients with a confirmed diagnosis of EA were retrospectively reviewed. Baseline characteristics were compared between patients with and without a prior history of CVA using logistic regression modeling. Read More

Megestrol Acetate Induced Paradoxical Embolism in a Sickle Cell Disease Patient.

Cureus 2019 Jun 26;11(6):e5004. Epub 2019 Jun 26.

Internal Medicine, Orange Park Medical Center, Orange Park, USA.

We report a case of a 43-year-old African American female patient with otherwise stable sickle cell disease (SCD) in which use of megestrol acetate for appetite stimulation quickly potentiated her prothrombotic state within just a few days. This resulted in infarcts involving the bilateral cerebral hemispheres suggestive of embolic infarcts and the patient was subsequently confirmed to have a patent foramen ovale (PFO). A widespread literature search in PubMed revealed that this is a rare case in the literature and that the effects of megestrol acetate use in patients with SCD have not been well studied. Read More
