BACKGROUND AND AIM: The clinical utility of transesophageal echocardiography (TEE) after brain ischemia (BI) remains a matter of debate. We aimed to evaluate the clinical impact of TEE and to build a score that could help physicians to identify which patients should better benefit from TEE. METHODS: This prospective, multicenter, observational study included patients over 18 years old, hospitalized for BI. TEE findings were judged discriminant if the results showed important information leading to major changes in the management of patients...

BACKGROUND: Transcatheter closure of patent foramen ovale (PFO) after cryptogenic stroke has long been a contentious issue. Herein, we pool aggregate data examining safety and efficacy of transcatheter closure of PFO compared with medical therapy following initial cryptogenic stroke. METHODS: We searched for randomized clinical trials (RCT) that compared device closure with medical management and reported on subsequent stroke and adverse events. Stroke was considered as the primary efficacy endpoint, whereas bleeding and atrial fibrillation were considered primary safety endpoints...

INTRODUCTION: The concept of embolic stroke of undetermined source (ESUS) has recently appeared to better characterise patients with cryptogenic stroke. PATIENTS AND METHODS: A systematic review of studies published since 2014 was performed to evaluate the epidemiology, clinical features and prognosis of patients with ESUS and their proportion among patients with cryptogenic stroke. RESULTS: Ten studies were identified with a total of 14,810 patients...

Brain abscess (BA) is an encapsulated infection and can be the consequence of head and cranio-maxillo-facial surgery or trauma, or may be secondary to cavernous thrombophlebitis, but is most frequently due to hematogenous septic dissemination from an adjacent site of infection, such as the paranasal sinuses, middle ear or oral cavity. We report a rare and unfortunate case of multiple BA caused by dental procedures in a young man with undiagnosed patent foramen ovale (PFO). Simple routine dental procedures, such as tooth brushing and professional oral hygiene, can predispose to life-threatening conditions...

A patent foramen ovale (PFO) is a common variant in cardiac anatomy found in 25% to 30% of U.S. adults. While PFOs are a normal part of fetal development and commonly seen in asymptomatic adults, they have been implicated in a variety of pathophysiologic conditions. The most clinically important of these is paradoxical embolization of venous thrombus resulting in stroke or systemic embolism. Various devices can be used to close PFOs via a transcatheter approach to prevent recurrent stroke. Data regarding the safety and effectiveness of these devices is rapidly evolving, with recent long-term results suggesting efficacy in preventing secondary stroke in carefully selected patients...

Platypnoea Orthodeoxia syndrome is defined by dyspnoea and hypoxaemia exacerbated by orthostatic positioning and alleviated in recumbency. This condition has been reported in association with pulmonary, hepatic and cardiac disease. We describe a case herein of a 79 year old female who developed severe hypoxaemia and dyspnoea post laparoscopic cholecystectomy. A difference in arterial blood gas oxygen tension was demonstrated in the supine and erect positions on arterial blood gas analysis. A Patent Foramen Ovale (PFO) with a right to left shunt was evident on echocardiogram employing colour doppler and agitated normal saline studies...

Paradoxical embolism through a patent foramen ovale is a very unusual event considering that this cardiac anomaly may be present in as much as 26% of the general population. We describe the case of a 68-year-old man with a pulmonary and paradoxical coronary embolism in the presence of a patent foramen ovale. The finding of a worm-shaped thrombus though the atrial septum together with the risk of further embolization through the atrial septum prompted surgical treatment.

OBJECTIVES: To examine long-term clinical outcomes with transcatheter patent foramen ovale (PFO) closure versus medical therapy alone in patients with cryptogenic stroke. BACKGROUND: A long-standing debate regarding the optimal approach for the management of patients with PFO after a cryptogenic stroke exists. METHODS: An electronic search was performed for randomized clinical trials (RCTs) reporting clinical outcomes with PFO closure vs. medical therapy alone after stroke...

An 81-year-old female developed dyspnea only upon assuming a sitting position. Trans-esophageal echocardiography demonstrated left-to-right shunt flow across the atrial septum when the patient was sitting, and right-to-left shunt flow when she was supine, along with severe aortic insufficiency. She was diagnosed as having platypnea-orthodeoxia syndrome and her symptoms were completely resolved following aortic valve replacement, closure of a patent foramen ovale, and shortening of an elongated ascending aorta...

The term cryptogenic stroke refers to a stroke for which there is no specific attributable cause after a comprehensive evaluation. However, there are differences between the diagnostic criteria of etiological classifications used in clinical practice. An improvement in diagnostic tools such advances in monitoring for atrial fibrillation, advances in vascular imaging and evidence regarding the implication of patent foramen oval on the risk of stroke specially in young patients are reducing the proportion of stroke patients without etiological diagnosis...

Atlantoaxial dislocation is a disorder that is characterized with loss of stability of the atlas and axis (C1-C2) with consequential loss of usual articulation. Although this condition is very common, no one has reported a case as young as our patients. We present a 7-month infant with bilateral paralysis of the lower limbs for four (4) months with no history of trauma. Computer tomographic (CT-scan) imaging revealed alantoaxial dislocation with severe cervical spinal cord compression. The odontoid process is displaced outwardly with no bone destruction...

BACKGROUND AND PURPOSE: Percutaneous transcatheter closure of patent foramen ovale (PFO closure) plus antiplatelet therapy has been shown to reduce the risk of recurrent stroke compared with medical therapy alone in carefully selected patients after cryptogenic stroke presumed to be from paradoxical embolism. Our objective was to determine the cost-effectiveness of PFO closure after cryptogenic stroke compared with conservative medical management from a US healthcare payer perspective...

A 72-year-old man was admitted to our hospital because of right upper limb monoplegia 8 hours after the initial intravitreal injection of aflibercept, which is an inhibitor of vascular endothelial growth factor. Magnetic resonance diffusion-weighted images showed recent ischemic lesions in the left corona radiata and the right superior frontal gyrus. Laboratory findings showed mild hyperfibrinolysis. A patent foramen ovale was diagnosed on transesophageal echocardiography; however, lower-extremity ultrasonography did not detect deep vein thrombosis...

AIMS: About one-third of ischemic stroke are cryptogenic. Paradoxical embolism through patent foramen ovale (PFO) has been identified as a possible cause of cryptogenic stroke. Therefore, PFO closure has been considered for secondary prevention of cryptogenic stroke. However, randomized clinical trials (RCTs) comparing PFO closure versus medical therapy led to conflicting results. Our objectives were to examine if PFO closure is superior to medical therapy alone for secondary prevention of cryptogenic stroke and to investigate whether PFO closure is associated with an increased incidence of atrial fibrillation/atrial flutter (AFL)...

The semi-sitting position is preferred in some surgeries of the posterior fossa and the cervical spine. At the same time, it is associated with the risk of air embolism. In the presence of a patent foramen ovale (PFO) with intracardial right-to-left shunt, an air embolism can result in a paradoxical embolism to the heart or brain. It is unclear whether the risk-benefit ratio favors the semi-sitting position in this scenario. Therefore, we conducted a systematic review of the relevant studies published after 2007 by searching the databases PubMed, Science Direct and the Cochrane Database of Systematic Reviews for relevant articles...

Atrial septal pouch is a recently described anatomical entity. We describe webbed left atrial septal pouch (LSP), a new variant in the spectrum of fusion of septum primum and septum secundum. In the continuum of the natural history of atrial septal closure from patent foramen ovale (PFO) to complete fusion of the septum, we propose the septal anatomy in our patient to be secondary to partially developed adhesions or septa. Potential association of LSP with stroke due to in situ thrombosis and atrial fibrillation has been described...
