Iron deficiency, ischaemic strokes, and right-to-left shunts: From pulmonary arteriovenous malformations to patent foramen ovale?
Has the recent identification of iron deficiency as a risk factor for ischaemic stroke in patients with pulmonary arteriovenous malformations (AVMs) unmasked a new paradigm for stroke/infarct pathogenesis? This commentary reviews evidence that spans associations between iron deficiency and ischaemic strokes, iron deficiency enhancement of platelet aggregation in response to serotonin/5HT, setti...
متن کاملImaging characteristics of ischemic strokes related to patent foramen ovale.
BACKGROUND AND PURPOSE Subclinical atrial fibrillation (AF) and patent foramen ovale (PFO) are the major causes of cryptogenic stroke, and neuroimaging may help distinguish the cause. We compared the imaging characteristics of ischemic stroke caused by PFO (PFO-stroke) and AF (AF-stroke). METHODS We recruited 117 patients with PFO-stroke and 358 patients with AF-stroke after excluding other c...
متن کامل[A right-to-left shunt through a patent foramen ovale without pulmonary hypertension].
We report the case of a man 67-years-old with right-to-left shunt through a patent foramen ovale in absence of pulmonary hypertension. The contrast and transesophageal echocardiography showed significant right-to-left shunt and provided insight about the mechanisms that cause it. The aortic root was enlarged compressing the right atrium. Surgical repair was performed, the foramen ovale was clos...
متن کاملIschaemic Strokes in Patients with Pulmonary Arteriovenous Malformations and Hereditary Hemorrhagic Telangiectasia: Associations with Iron Deficiency and Platelets
BACKGROUND Pulmonary first pass filtration of particles marginally exceeding ∼7 µm (the size of a red blood cell) is used routinely in diagnostics, and allows cellular aggregates forming or entering the circulation in the preceding cardiac cycle to lodge safely in pulmonary capillaries/arterioles. Pulmonary arteriovenous malformations compromise capillary bed filtration, and are commonly associ...
متن کاملTransient right-to-left shunting through a patent foramen ovale secondary to unilateral diaphragmatic paralysis.
A 57 year old patient presented with unilateral diaphragmatic paralysis and severe hypoxaemia secondary to transient right-to-left interatrial shunting through a patent foramen ovale. The final diagnosis was made because of the initial detection of a shunt while the patient was breathing 100% oxygen.
