Microanigiographlic examinatioin of the pulmoniary arterial svstem in 12 n1ewborn in1fants with conicomitanit steniosis or atresia of the aortic anid mitral orifices showed that the intrapulmonary arterial pattern is inifluenced by the state of the forameni ovale. In inifanlts with aortic atresia with a prematuirely closed foramein ovale, that is cases in which the left side of the heart is a c...
The mean percentage of cryptogenic strokes among ischemic strokes is 31%, of which one-third may be associated with patent foramen ovale. The foramen ovale is required for blood flow through the fetal atrial septum. It is formed as of the fourth week of gestation, and this leads to right-left interatrial shunt that allows the passage of oxygenated blood to systemic circulation. In 75% of cases,...
BACKGROUND Many have proposed a relation between presence of a patent foramen ovale, with or without atrial septal aneurysm, and cryptogenic stroke. The effect of foramen ovale closure on the risk for subsequent strokes is unknown. METHODS AND RESULTS Transcatheter closure of a patent foramen ovale was undertaken in 36 patients with known right-to-left atrial shunting and presumed paradoxical...
INTRODUCTION AND OBJECTIVES To investigate the relationship between patent foramen ovale and cryptogenic stroke in patients aged > or =55 years. METHODS This prospective study determined the presence of patent foramen ovale and atrial septal aneurysm using transesophageal echocardiography in 262 consecutive patients with a diagnosis of probable cryptogenic stroke. Data from 44 patients aged >...
BACKGROUND Right-to-left shunt through a patent foramen ovale is frequently diagnosed by contrast echocardiography and can be particularly prominent in the presence of elevated pressures in the right side of the heart. Its prognostic significance in patients with pulmonary thromboembolism, however, is unknown. METHODS AND RESULTS The present prospective study included 139 consecutive patients...
background: percutaneous transcatheter closure has been proposed as an alternative to surgical closure or long-term anticoagulation in patients with presumed paradoxical embolism and patent foramen ovale (pfo). methods: there were two symptomatic patients (29 and 47 years old) who underwent percutaneous transcatheter closure of pfo after at least two events of cerebral ischemia; one embolic eve...
The correct radiographic identification of ossification of the pterygospinous and pterygoalar ligaments plays an important role in surgical procedures for the treatment of trigeminal neuralgia. Most of these procedures are performed through the foramen ovale, a site where these ligaments can be found to be partially or completely ossified. We studied the radiographic features of these ossified ...
background: one of the important etiologies for cryptogenic stroke is paradoxical embolization secondary to patent foramen ovale (pfo). foramen ovale can secondarily reopen due to pulmonary arterial hypertension (pah) which is common among the older age. pah is known as a frequent and life threatening complication of copd. the aim of this study was to determine the prevalence of pfo between cop...
BACKGROUND Malaria in humans is caused by apicomplexan parasites belonging to 5 species of the genus Plasmodium. Infections with Plasmodium ovale are widely distributed but rarely investigated, and the resulting burden of disease is not known. Dimorphism in defined genes has led to P. ovale parasites being divided into classic and variant types. We hypothesized that these dimorphs represent dis...
It has been proposed that ovale malaria in humans is caused by two closely related but distinct species of malaria parasite, Plasmodium ovale curtisi and Plasmodium ovale wallikeri. It was recently shown that these two parasite types are sympatric at the country level. However, it remains possible that localised geographic, temporal or ecological barriers exist within endemic countries which pr...
