Patent Foramen Ovale and Stroke–Current Status [PDF]

Journal of Stroke, 2015
Patent foramen ovale (PFO) is growing in clinical interest because of a renewed focus on embolic stroke of undetermined source (ESUS), the PFO attributable fraction (the 10-point Risk of Paradoxical Embolism score), technical advances in PFO diagnosis ...

Undiagnosed patent foramen ovale: a rare cause for acute pulmonary embolism and cryptogenic stroke

Asian Journal of Internal Medicine
Patent foramen ovale (PFO) is a congenital cardiac anomaly found in 25-30% of the population. Though often asymptomatic, it may lead to paradoxical embolism and cryptogenic stroke.

Bryozoan‐Rich Carbonate Units of the Erfoud Area (SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

Geological Journal, EarlyView.
In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

Paradoxical Embolism and a Patent Foramen Ovale.

, 1998
Patients who sustain an unexplained stroke or peripheral ischemic event should be examined for paradoxical embolism via right-to-left shunting. The confirmation of a patent foramen ovale by echocardiography is simple and noninvasive, and should suggest ...

Pulmonary Arteriovenous Malformation can be Associated with Embolic Stroke of Undetermined Source (ESUS)

European Journal of Case Reports in Internal Medicine, 2019
Pulmonary arteriovenous malformations (PAVMs) are rare vascular anomalies. Alternative designations are pulmonary arteriovenous fistulae or aneurysms. Although mostly asymptomatic, PAVMs can cause respiratory symptoms due to right-to-left shunt.

“Thinking Out Loud” and “Pivoting on the Fly”—An Empirical Review and Critical Incident Study of How Physicians Engage in Incidental Learning Amidst Complexity

Human Resource Development Quarterly, EarlyView.
ABSTRACT This study explores incidental learning among physicians navigating uncertainty during the COVID‐19 pandemic. Using a constructivist research design, we conducted a literature review of 13 empirical studies on incidental learning in complexity and analyzed critical incident interviews with 12 emergency medicine and intensive care physicians ...

High-Risk Pulmonary Embolism with Impending Paradoxical Embolism Successfully Treated with Percutaneous Catheter-Based Thrombectomy

, 2011
Impending paradoxical embolism is a rare condition defined as the presence of an entrapped thrombus through the patent foramen ovale. This diagnosis is usually made from echocardiography or a thoracic-CT scan performed in patients with suspected ...

The Paradox of Paradoxical Embolism and Recurrent Stroke

JACC: Cardiovascular Interventions, 2014
Ischemic stroke is a complex condition with multiple possible causes, but up to 30% to 40% of patients have no identifiable source despite a “thorough” evaluation; that is, the strokes are cryptogenic.
