BACKGROUND Atrial fibrillation (AF) is the most common clinically significant cardiac arrhythmia. However, diagnosis of intraventricular dyssynchrony in patients with AF is difficult due to beat-to-beat variation. Additionally, evaluation of mechanical dyssynchrony in the traditional method is based on average of 5 to 10 beats, which is exhausting and time consuming. Single-beat evaluation of a...

BACKGROUND AND PURPOSE Before the advent of MR imaging, intraventricular cysts were difficult to diagnose noninvasively. Among the invasive procedures used were contrast ventriculography and CT ventriculography. MR imaging, with its multiplanar imaging capabilities, excellent depiction of tissue contrast, and versatile parameters, is an important tool in the assessment of intraventricular cysti...

Intracranial silicone oil is a rare complication of intraocular endotamponade with silicone oil. We describe a case of intraventricular silicone oil fortuitously observed 38 months after an intraocular tamponade for a complicated retinal detachment in an 82 year-old woman admitted in the Department of Neurology for a stroke. We confirm the migration of silicone oil along the optic nerve. We dis...

Rats were infused with norepinephrine or saline intraventricularly in a free-field situation and while performing a continuous avoidance task (Sidman avoidance). The results indicate that central administration of norepinephrine may lead to behavioral activation in the rat.

Intraventricular hemorrhage with congenital cytomegalovirus (CMV) infection is rare and has been reported only in extremely premature infants or in association with thrombocytopenia. We report the first case of a full-term male infant with congenital CMV infection and intraventricular hemorrhage with a normal platelet count and coagulation profile. The infant also had a left subependymal cyst a...
