The aim of our study was to determine when foramen ovale recordings add useful information to scalp EEG recordings and magnetic resonance imaging (MRI) with hippocampal measurements. We evaluated the outcome of 79 patients with non-lesional partial epilepsy with presumed temporal seizure onset. Ictal foramen ovale recordings were performed in 16 patients with normal MRI (MRI-negative group) and 41 patients with lateralizing MRI but non-lateralizing scalp EEG (discordant group). 22 patients with concordant MRI and scalp EEG were not investigated with foramen ovale recordings (concordant group). The seizure-free rate was higher in concordant than discordant patients despite additional investigation with foramen ovale electrodes (71 and 55% seizure free, respectively). No useful localizing information was added with foramen ovale recordings in MRI-negative patients.

The foramen ovale is an important communication between the two sides of the heart prenatally, allowing the left ventricle to carry its share of the prenatal circulation and providing flow for growth of left ventricular structures. Restriction of the foramen ovale appears to be a serious disorder of the fetus and can be associated with fetal hydrops, arrhythmias, and other signs of major fetal compromise. This article reviews our experience with restriction of the foramen ovale and provides a summary of the pathologic and echocardiographic literature related to the etiology and effects of restrictive foramen ovale in the fetus. ...

Atrial septal defects (ASD) are one of the most prevalent congenital heart malformations, with an estimated 56 cases per 100,000 births.[52] This heart defect involves a communication between the left and right atria, and can be subdivided into five main types based on the nature of the defect. The most common ASD is a patent foramen ovale. Throughout fetal development, the foramen ovale functions to shunt oxygenated blood from the right atrium into the left atrium.[53] After birth, the now functioning respiratory system of the newborn results in elevated pressure in the left atrium relative to that of the right.[54] This induces fusion of the septum primum and septum secundum which closes the foramen ovale, leaving a remnant known as the fossa ovalis.[53] Incomplete closure results in a patent foramen ovale. This condition is present in nearly all newborns and typically closes within the first month, however complete closure is achieved in only 70-75% of adults.[52] A patent foramen ovale is ...

The port entry, therefore, must be detected. In our case, it seemed to be the colonic adenoma. Scarce literature underlines the plausibility for our theory and is sequentially presented here to explain the bubbles journey from the port of entry to the cardiac cavities.. The first stage is the way to the portal venous system, the venous drainage of the colonic cancer described. Hepatic portal venous gas, is a rare finding, but is described in a variety of intestinal pathologies such as infections, ulcers or ileus.6 Li et al describe hepatic portal gas in a patient with colonic cancer,7 suggesting that neoplastic pathologies can also serve as a port of entry.. The transition of the bubbles from the portal venous system to the cardiac cavities must have been facilitated by the metastases: air usually can be cleared from all organs within minutes to hours, as shown in a study after cardiac surgery.8 The liver also seems to effectively clear hepatic portal gas.9 However, portosystemic and ...

A total of 817 foramina ovalia (411 left-sided, 406 right-sided) from cranial base images of 424 dry crania were included in the study. The centroid point of each foramen ovale was identified. A sagittal plane through the posterior-most molar (molar plane) and a coronal plane passing through the articular eminences of the temporal bones (inter-eminence plane) were superimposed on images. The distances of the planes from the centroids of the foramina were measured. Also, counts were taken to assess how often the planes and their intersections crossed the boundary of the foramen ovale. ...

The embryological aetiology of LASP is incomplete fusion of the septum primum and septum secundum during the closure of foramen ovale. Fusion limited to the caudal portion of the zone of overlap leads to creation of the LASP.1 Mazur et al reported the presence of LASP in 40.8% of 294 healthy adult hearts in postmortem examination. The mean volume of the LASP was 0.31±0.11 mL, which makes up only 13.6%±9.4% (range: 3.1%-44.9%) of the appendage, and the average depth of the LASP was 8.4±5.1 mm.2 Hence, the LASP is a relatively small structure. However, in our case, the depth of LASP with a giant flap spreading to LA cavity (the white arrows in figure 1) was 30 mm. As the LASP cavity is surrounded by transverse muscle, it was difficult to insert catheters from the septal wall and isolate the right pulmonary veins. We consider that (1) the presence of LASP may also cause blood stasis in the LASP cavity, increasing the risk of blood clots formation and potentially lead to ischaemic stroke,3 (2) ...

A method for closing a patent foramen ovale in the heart tissue of a patient may include percutaneously advancing a connector applicator to the patent foramen ovale, registering the connector applicator with the patent foramen ovale, deploying connectors into heart tissue to close the patent foramen ovale; and percutaneously removing the connector applicator from the heart. One or more anchors may be used to register the connector applicator with the patent foramen ovale. The connector applicator may include a driver having a longitudinal passage therein, where at least part of at least one connector is positioned within the passage.

The CT examination when done showed a small epidural enhanced left petrous collection with downward extension to the superior pharyngeal mucosal space, extensive destruction of the ipsilateral petrous apex and opacification of the tympanic cavity and mastoid air cells, with mastoidal sclerosis. The MRI showed the left petrous apex lesion, which was hypointense as seen on T1-weighted images, hyperintense when seen on T2-weighted images and enhanced by using gadolinium, and also demonstrated the small infracranial extension. CT and MRI are highly sensitive in detecting petrous apex lesions. As in this case, they permit the identification of apical osteomyelitis surrounded by a phlegmon collection. When the petrous apicitis is large enough, it can injure the VI cranial nerve where it passes through the petrous apex in Dorellos canal, on its way to the orbit via the cavernous sinus. Then, the patient presents with the symptoms of Gradenigos syndrome: otitis media, deep facial pain along the ...

This defect is present in every newborn baby. It is a gap in the wall between the upper two chambers of the heart, which should close soon after birth.. Whilst a baby is in the womb, oxygen is supplied by the placenta via the umbilical cord and the babys lungs are not expanded and require only a small amount of blood for them to grow. The patent foramen ovale is one of a number of natures short circuits which allows blood to bypass the babys lungs whilst in the womb.. Usually the ductus arteriosus (a connection between the aorta and the lung artery) and the other short circuits close within a few days of birth, and the connections between the two sides of the heart no longer exist. The resistance to blood flow quickly falls with the onset of breathing and the left side pressures become greater than the right, this pushes the flap of the Patent Foramen Ovale closed and in most people it seals over.. ...

Patent foramen ovale (PFO) is an anatomical interatrial communication with potential for right-to-left shunt. Foramen ovale has been known since the time of Galen.

Patent foramen ovale (PFO) is the most common anatomical cause of an interatrial shunt. It is usually asymptomatic but may cause paradoxical embolism, manifesting as stroke, myocardial infarction or visceral/peripheral ischaemia. PFO is a risk factor for stroke and may be associated with migraine with aura. New evidence suggests PFO closure reduces the risk of recurrent ischaemic stroke in a highly selected population of stroke survivors: those aged 60 years or younger with a cryptogenic stroke syndrome, a large right-to-left shunt, an atrial septal aneurysm and no evidence of atrial fibrillation. They benefit from percutaneous PFO closure in addition to antiplatelet therapy, rather than antiplatelet therapy alone. Current evidence does not support PFO closure in the treatment of migraine ...

We read with great interest the article by Bonanni et al1 containing images of a patient with a fluttering thrombus in a patent foramen ovale. This entity has more frequently been called impending paradoxical embolism,2,3 because the thrombus is found trapped within the atrial septum on its way to a paradoxical systemic embolism.4 It would be interesting to understand why the authors chose to treat this fluttering thrombus by anticoagulation alone in a young patient (56 years old) with apparently no major previous medical or surgical history.. In a systematic review of the literature including 174 patients with impending paradoxical embolism published between 1985 and 2008,5 we previously reported a 30-day mortality of 15.5% (27 of 174) and systemic embolism after treatment initiation of 6.8% (12 of 174) in this patient population. Both of these end points were significantly increased in patients treated with anticoagulation (early mortality, 25.6%; systemic embolism after diagnosis, 13%) ...

The random placement of pacing lead in the left ventricle (LV) is a rare and late diagnosed complication of the permanent heart stimulation. In most cases the intracardiac electrode moves through the interatrial septum or through the patent foramen ovale to the LV. On ECG the sets of QRS have morphology of right bundle branch block. The decisive survey used to identify this complication is echocardiography, especially transesophageal study. The malposition of the pacing electrode is associated with the risk of thromboembolic complications. The treatment consists of early lead removal. In case of lack of such a possibility the chronic anticoagulation treatment has to be started. The paper presents a case of incorrect position of pacing electrode in LV in a patient with PFO. ...

Methods, devices and systems for treating patent foramen ovale (PFO) involve advancing a catheter device to a position in a heart for treating a PFO, bringing tissues adjacent the PFO at least partially together, and applying energy to the tissues to substantially close the PFO acutely. Catheter devices generally include an elongate catheter body, at least one tissue apposition member at or near the distal end for bringing the tissues together, and at least one energy transmission member at or near the distal end for applying energy to the tissues. In some embodiments, the tissue apposition member(s) also act as the energy transmission member(s). Applied energy may be monoploar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like.

The presence of patent foramen ovale was assessed by contrast echocardiography, performed blinded for type of stroke. The association between patent foramen ovale and type of stroke was ...

The foramen ovale is a normal opening between the upper two chambers of an unborn babys heart. It usually closes soon after the babys birth - when it doesnt, its called a patent foramen ovale.

The lingual nerve and its adjacent structures were observed and measured on 32 adult cadavours. Its length was 69.7 mm and it was divided, bounded by the internal pterygoid muscle, into three segments and the length and diameter of them were respectively measured. According to its relationship with the lingual nerve, the submandibular ganglion can be classified into fusion type (being 46.9%) and free type (being 53.1%), and its superoinferior and transeversal diameters were separately measured to be 2.7 and 2.9 mm. The lingual nerve and its lingual branches were closely related to submandibular duct and there were two intersects. The relation and clinical significance of the third segment of lingual nerve and its neighbor structures were studied.

We read with interest the review paper on paradoxical embolism by Windecker et al. (1). It was suggested, on the basis of available evidence from published reports, that device closure of patent foramen ovale (PFO) should be considered in patients with first-time cryptogenic stroke, particularly in those with high-risk criteria, such as presence of an atrial septal aneurysm (ASA), large PFO, Eustachian valve, or Chiari network. The viewpoints of Windecker et al. on those with high-risk criteria should be discussed and clarified.. With routine clinical application of intracardiac echocardiography (ICE) in more than 3,000 cases of left heart ablation, it has been proven that ICE is an excellent ultrasound modality that can be used for diagnosis of an ASA, PFO, variant Eustachian valve, or Chiari network (2). A statistical analysis of 938 consecutive cases with left heart ablation from 2012 to August 2014 showed that the incidence of ASA was 6.9% and the incidence of PFO was 6.4%. A variant ...

During the fourth week of gestation, a pair of anterior cardinal veins form that drain the cephalic part of the embryo and a pair of posterior cardinal veins form that drain the rest. Anterior and posterior cardinal veins join to form a short common cardinal vein (duct of Cuvier), which opens into the respective horns of sinus venosus. The proximal portions of the right anterior cardinal veins and right common cardinal vein form the RSVC. The left anterior cardinal veins normally obliterate to form the ligament of Marshall, whereas the left horn of the sinus venosus and adjacent portion of the left common cardinal vein form the CS. Persistence of the left anterior cardinal vein forms the left SVC, which always continues with the CS as the left common cardinal vein that is part of both the CS and left SVC. Flow of PLSVC blood into the CS results in its enlargement, and a dilated CS is often the first clue for the diagnosis of PLSVC during echocardiography. In 82% to 90% of cases, PLSVC is ...

These develop at the lower end of the truncus arteriosus. At this level there are four swellings of sub-endocardial tissue - the right and left bulbar swellings and two acessory dorsal and ventral swellings.

In certain situations, despite normal RA pressure, right-to-left shunt may develop. These situations may be caused by transient, rather than mean, interatrial right-to-left pressure gradients resulting from a Valsalva-like activity, such as coughing, or they may be caused by contraction of the RA against a stiff right ventricle. Further preferential flow from the IVC toward the fossa ovalis may be the mechanism responsible for right-to-left shunt in some cases (1). For example, Gallaher et al. (21) described three patients with a PFO, normal RA pressure, and a large eustachian valve and postulated that the eustachian valve was responsible for directing IVC flow toward the PFO, as is the case in prenatal life. Several other case reports describe hypoxemia occurring in association with a PFO in otherwise healthy subjects. Strunk et al. (1) described four patients with PFO who experienced decreased oxygen saturation and dyspnea. One patient had mild chronic obstructive pulmonary disease, and the ...

Nevertheless, the most novel thing about this intercavity application is its treatment of the patent foramen ovale. It is estimated that up to 20% of the public have PFO, although not all need or are suitable for treatment. This is why we await some symptom as there are no studies indication which PFOs should be closed or not if there have been no previous symptoms.
