BACKGROUND Hyperdense middle cerebral artery sign is an appearance of the middle cerebral artery on non-contrast-enhanced computed tomography. Embolic occlusion of the pulmonary arterial system is referred to as pulmonary embolism. When pulmonary embolism coexists with a patent foramen ovale, increased pressure in the right atrium may result in widening of the foramen and consequently, cause se...

An atrial septal aneurysm may be associated with a patent foramen ovale. When paradoxical emboli result, the shunt must be closed and the atrial septal aneurysm excised. A reversed buttoned occluder device was successfully used for the transcatheter treatment of this condition.

There is currently no consensus on the optimal management of cryptogenic stroke in the presence of a patent foramen ovale (PFO). Some physicians do not believe in the added value of PFO closure in cryptogenic stroke, whereas, for others, cryptogenic stroke represents a situation where PFO closure would be the best management. Because of a lack of well-designed randomized trials, guidelines do n...

Chiari networks are present in the right atrium in a minority of the population and are usually of no clinical significance. On the other hand it may associate some pathological changes, as patent foramen ovale, intraatrial thrombus or atrial arrhythmias. We present the case of an asymptomatic young woman diagnosed with Chiari network during a routine echocardiography.

We present two cases of decompression illness in women in whom the initial symptom causing distress after completion of the dives was breast pain. Both women were also subsequently found to have a patent foramen ovale. We postulate that breast pain may be an unusual under-recognized manifestation of decompression illness.
