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.
Objective: To determine and compare the prevalence of patent foramen ovale in patients with stroke of undetermined origin (cryptogenic) and in patients with stroke of determined origin to assess the possible role of patent foramen ovale as a risk factor for cryptogenic stroke.. ▪ Design: Cross-sectional study with nested case-control analysis.. ▪ Patients: A total of 146 patients (73 men, 73 women) with acute ischemic stroke referred to the echocardiography laboratory for evaluation.. ▪ Setting: Neurovascular Unit and Echocardiography Laboratory, Columbia-Presbyterian Medical Center, New York, New York.. ▪ Measurements: Patients were considered to have strokes of determined origin or cryptogenic strokes according to National Institute of Neurological Disorders and Stroke (NINDS) Stroke Data Bank criteria. 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 ...
In a 22-year-old woman suffering from ischemic stroke affecting the posterior cerebral artery, clinical work-up ruled out cardiovascular and neurological pathologies except patent foramen ovale (PFO) with septal aneurysm and complete bubble filling of the left atrium as demonstrated by echocardiography. The patient was scheduled for transcatheter PFO closure. Peri-interventional 3-dimensional transesophageal echocardiography revealed a PFO tunnel and a left atrial chord keeping the PFO open, with consequent continuous left to right shunting (A to C; Online Video 1). Balloon sizing demonstrated a tunnel diameter of 16 mm (D). A 16-mm Amplatzer ASD occluder (St. Jude Medical, St. Paul, Minnesota) was implanted (E and F, Online Video 2) adhering to the atrial chord. Intraprocedural imaging was extremely helpful for device selection and positioning of the left atrial occluder disk to facilitate partial coverage and slightly lifting of the chord, yet no longer directly adjacent to the interatrial ...
Devices and methods are disclosed herein for closing a patent foramen ovale. The devices are deployed at the foramen ovale to secure the septum secundum and septum primum together, thus sealing the foramen ovale. Disclosed are devices that may be inserted through a piercing in the septum secundum and septum primum to secure the septa together. Also disclosed is a delivery device to be used in connection with the devices and methods described. In some embodiments, the devices include an expandable member that secures at least one side of either the septum secundum or septum primum to secure the two septa together.
This advisory, published at the end of July in Neurology, is an update from the 2004 AAN guideline on secondary stroke in PFO patients, which concluded that the "optimal therapy" for this patient population was "unknown". Additional studies prompted the AAN to analyse whether percutaneous closure of PFO is superior to medical therapy alone and anticoagulation is superior to antiplatelet therapy for the prevention of recurrent stroke in patients who have had a cryptogenic ischaemic stroke or transient ischaemic attack (TIA).. In order to update the 2004 guidelines, a panel of neurologists, cardiologists, and an internist with expertise in stroke and PFO who had no financial conflicts performed a literature search on the subject. Messé et al identified three key studies on percutaneous PFO closure. The first was CLOSURE I, a multicentre randomised, open-label trial of percutaneous closure, which compared the StarFlex device (NMT Medical) with medical therapy alone in adult patients with PFO and a ...
TY - JOUR. T1 - Patent foramen ovale and infarct volume in cryptogenic stroke. AU - Jung, Jin-Man. AU - Lee, Jong Young. AU - Kim, Hye Jin. AU - Do, Youngrok. AU - Kwon, Sun U.. AU - Kim, Jong S.. AU - Song, Jae Kwan. AU - Kang, Dong Wha. PY - 2013/1/1. Y1 - 2013/1/1. N2 - Background: The causal relationship between patent foramen ovale (PFO) and stroke is controversial. We hypothesized that if PFO is a pathway of embolic source, there might be a correlation between PFO characteristics (ie, size or extent of shunt) and ischemic lesion burden (ie, infarct volume and number). Methods: From ischemic stroke patients admitted to Asan Medical Center between January 2000 and October 2007, we identified those who had (1) acute ischemic lesion on diffusion-weighted imaging within 5 days of symptom onset and (2) cryptogenic stroke and only PFO detected by transesophageal echocardiography. PFO characteristics on echocardiographic studies included size, shunt grade, shunt pattern, and the presence of atrial ...
Rationale The utility of patent foramen ovale (PFO) closure for secondary prevention in patients with prior cryptogenic stroke is uncertain despite multiple randomized trials completed to date. Aims The Gore REDUCE Clinical Study (REDUCE) aims to establish superiority of patent foramen ovale closure in conjunction with antiplatelet therapy over antiplatelet therapy alone in reducing the risk of recurrent clinical ischemic stroke or new silent brain infarct in patients who have had a cryptogenic stroke. Methods and design This controlled, open-label trial randomized 664 subjects with cryptogenic stroke at 63 multinational sites in a 2:1 ratio to either antiplatelet therapy plus patent foramen ovale closure (with GORE® HELEX® Septal Occluder or GORE® CARDIOFORM Septal Occluder) or antiplatelet therapy alone ...
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.. ...
Numerous transcatheter PFO closure systems are commercially available or under investigation. Some of the double umbrella devices leave a relatively large amount of foreign material in the atria, which can lead to thrombus formation on the device (9,10). We reported in a study with 1,000 patients that the incidence of thrombus formation is 2% (9). Furthermore, distortion of the septum due to a wire might be the cause of atrial fibrillation in some patients.. One of the advantages of the SeptRx device is the minimal material in the left atrium. So far, no thrombus formation has occurred, and the unique design of the device might help to minimize chronic complications such as thrombus formation or atrial fibrillation. A few other new devices are designed to minimize the incidence of thrombus formation. The BioSTAR device (NMT Medical, Boston, Massachusetts), reported by Mullen et al. (11), is a bioabsorbable septal repair device that is mostly replaced with healthy native tissue. According to the ...
The primary objective is to determine if patent foramen ovale (PFO) closure with the GORE® HELEX® Septal Occluder / GORE® CARDIOFORM Septal Occluder plus antiplatelet medical management is safe and effective and reduces the risk of recurrent stroke or imaging-confirmed transient ischemic attack (TIA) when compared to antiplatelet medical management alone in patients with a PFO and history of cryptogenic stroke or imaging-confirmed TIA.. A co-primary objective is to demonstrate that medical management plus closure with the study device reduces the risk of new brain infarct compared to medical management alone ...

Sukernik and Bennett-Guerrero (1) present a thorough and complete review of anatomy and physiology of patent foramen ovale (PFO), followed by an excellent discussion of echocardiographic techniques for diagnosing it. Subsequently, they analyze the pros and cons of surgical closure of an intraoperatively diagnosed "incidental" PFO.. Their article is remarkable because it discusses the indication for PFO closure from an uncommon viewpoint. Most literature dealing with adult PFO revolves around the risk of recurrent paradoxical embolism. The therapeutic options are anticoagulation or interventional PFO closure to prevent recurrency, and the relative ease of interventional closure has led to increasing numbers of such procedures performed by interventional cardiologists. The dilemma is the nearly always putative nature of paradoxical embolism across a PFO. Frequently, neither the embolic nature of the neurologic event nor the absence of other potential sources (e.g., paroxyxsmal atrial fibrillation) ...
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 ...
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.
BACKGROUND: Migraine is a prevalent and disabling disorder. Patent foramen ovale (PFO) has been associated with migraine, but its role in the disorder remains poorly understood. OBJECTIVES: This study examined the efficacy of percutaneous PFO closure as a therapy for migraine with or without aura. METHODS: The PREMIUM (Prospective, Randomized Investigation to Evaluate Incidence of Headache Reduction in Subjects With Migraine and PFO Using the AMPLATZER PFO Occluder to Medical Management) was a double-blind study investigating migraine characteristics over 1 year in subjects randomized to medical therapy with a sham procedure (right heart catheterization) versus medical therapy and PFO closure with the Amplatzer PFO Occluder device (St ...

Background: Paradoxical embolism via a patent foramen ovale (PFO) is a rare event in the puerperium as a cause of stroke. Case: We report a 21-year-old, G4P3A1 woman with the symptoms of convulsion, stroke and unconsciousness 1 week after cesarean delivery. An infarction was detected in both frontal lobes, and echocardiography and MRI confirmed the PFO. Her follow-up course with low-molecular weight heparin and then warfarin for 6 months was uneventful. Conclusion: Patients with an unexplained arterial event should be screened for PFO and possible paradoxical embolism. Copyright (c) 2008 S. Karger AG, Basel. ...
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%) ...

It is estimated that 25% to 30% of the worlds population, or 1.7 to 2.0 billion individuals, have patent foramen ovale (PFO). The vast majority of these people will have no problem associated with this condition. Very rarely, the pathogenesis of stroke or peripheral arterial embolization includes paradoxical embolization related to a thrombus formed in the systemic venous system or the right atrium and its crossing the interatrial septum via a PFO (1). In recent years, it has been suggested that patients with cryptogenic strokes or transient ischemic attacks (TIA) have a higher prevalence of PFO (2,3). Furthermore, the presence of PFO has been implicated in many other pathological entities, such as migraine headaches, orthodeoxia-platypnea syndrome, decompression illness, refractory hypoxemia, and sleep apnea syndrome (4,5).. The ingenuity and creativity of physicians, inventors, and the medical device industry have led to the design of systems capable of closing PFOs using a percutaneous ...
TY - JOUR. T1 - Transesophageal contrast echocardiography is not always the gold standard method in the identification of a patent foramen ovale: A clinical case. AU - Novo, Salvatore. AU - Costa, Francesco. AU - Lunetta, Monica. PY - 2015. Y1 - 2015. N2 - In the embryo, Eustachian valve is a crescent-shaped membrane extending from the lower margin of the inferior vena cava and the ostium of the coronary sinus into the right atrium toward fossa ovalis and tricuspid valve. At birth, after the functional closure of the foramen ovale, the Eustachian valve loses its function, reducing to an embryo remnant. According to growing evidence, a persistent Eustachian valve is a frequent finding in patients with a patent foramen ovale (PFO). By directing the blood from the inferior cava to the interatrial septum, it may prevent the spontaneous closure of PFO after birth and indirectly predispose to paradoxical embolism. Transesophageal contrast enhanced echocardiography (cTEE) is considered the gold ...

FREIBURG, Germany -- Its not just young patients with patent foramen ovale who are at elevated risk for cryptogenic stroke, according to a study conducted here.
Background: Haemodialysis (HD) circuits are known to produce microemboli. Patent foramen ovale (PFO) may be important in HD patients by allowing right to left intracardiac shunting of microemboli (blood clots or microbubbles), which may pass into the cerebral circulation.. Methods: We undertook bubble contrast transthoracic echocardiography to identify PFO in HD patients and in a control population of peritoneal dialysis patients. We interrogated draining arteriovenous fistulae to confirm that microemboli are created during HD. We then undertook transcranial Doppler scanning of the middle cerebral artery before and during dialysis, with and without Valsalva augmentation, to detect cerebral microemboli in HD patients and in the control group.. Results: Eighty patients (age 60.4 ± 15.0 years) were recruited to the study. In 12 of 51 HD patients and five of 29 peritoneal dialysis patients a PFO was found (21.3%). Ultrasound scanning of draining arteriovenous fistulae showed a significant ...
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.

PFO has been linked to stroke, transient ischaemic attacks, heart attacks, migraine with aura, peripheral embolism, shortness of breath (platypnea orthodeoxia), decompression sickness in divers and high-altitude sickness. There are certain anatomical features that make some PFOs higher risk than others. Dangerous PFOs are ones that are large, have an atrial septal aneurysm, a Eustachian valve or a promiant Chiari network. This features can be diagnosed using a transoesophageal echocardiogram.. A PFO can be closed using an umbrella device. The procedure is performed under general anaesthesia or conscious sedation. After a small incision is made in the groin, a long think tube called a catheter is inserted into a vein in the leg. The PFO closure device is then guided through the catheter to the heart and once there it is implanted. A couple of months after the PFO closure device is implanted, tissue begins to cover the device. You will generally be discharged from hospital within 24 hours of the ...
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.
In this multicentre cohort study of nearly 2000 patients who received a diagnosis of ischemic stroke or TIA, 68% had an echocardiogram (most often a transthoracic echocardiogram), and the results were normal 86% of the time. Overall, the 2 most common clinically actionable findings for secondary stroke prevention were cardiac thrombus and patent foramen ovale. Among patients with cryptogenic stroke, the prevalence of patent foramen ovale on echocardiography was more than 3 times higher than patients without cryptogenic stroke.. Previous studies have provided a wide range of estimates (2%-37%) for how often "clinically relevant" findings are detected on echocardiogram for patients with an ischemic stroke.10-12,22 The wide range is partially related to changing criteria for what is considered clinically relevant. For example, 1 study published in 2003, of 853 patients with stroke, found on transthoracic echocardiogram that nearly 20% had dilated cardiomyopathy.12 Based on the dilated ...

An updated recommendation from the American Academy of Neurology (AAN) states that catheter-based closure should not be routinely recommended for people who have had stroke and also have a heart defect called a patent foramen ovale (PFO), a channel between the top two chambers in the heart. To develop the advisory, researchers reviewed all available scientific studies on people with PFO who also had an ischemic stroke, which was a stroke caused by a blood clot, or a transiet eschemic attack, which is an episode of temporary stroke symptoms. "Compared with other way to prevent a second stroke, such as medications to reduce blood clots, the devices used to close a patent foramen ovale have limited evidence to support their use," said practice advisory author Steven R. Messe, MD, with the Perelman School of Medicine at the University of Pennsylvania in Philadelphia and a Fellow of the AAN. "Its still uncertain how effective these devices are in reducing stroke risk, and the procedure is associated ...
Transesophageal echocardiography was performed to verify the expected intracardiac shunt. Because of inadequate Valsalva maneuver, it was not possible to exclude a patent foramen ovale); however, intracardiac shunts of other origin were excluded. Following a positive transcranial Doppler test, a right heart catheterization was performed without any evidence of either a patent foramen ovale by catheter exploration or a pulmonary arteriovenous malformation by pulmonary angiography.. Because the patient refused further investigations, she was discharged on oral anticoagulant therapy for the symptomatic antiphospholipid syndrome without aspirin, because atherosclerosis was not present in the coronary arteries.. Acute myocardial infarction (AMI) in women of childbearing age is rare. Pregnancy, however, increases the risk of AMI 3- to 4-fold.1 The incidence of pregnancy-related AMI ranges between 1:16 000 and 35 000, and a mortality rate of 5% to 11% has been reported.2 The presence of ...

He completed fellowships in cardiology, interventional cardiology and heart failure and cardiac transplantation at the Ochsner Clinic Foundation as well. He specializes in carotid stenting and the closure of the atrial septal defect and patent foramen ovale. Both procedures are innovative stroke prevention strategies that provide patients minimally invasive alternatives to surgery. Carotid stenting provides patients who are a high risk for surgery an alternative to the carotid endarterectomy procedure. The closure of the atrial septal defect and patent foramen ovale provides patients with an alternative to open heart surgery. Because both procedures are less invasive than traditional surgeries, patients are usually discharged the next day. He also serves as the head of the Legacy Heart Center Vein and

An important part of these trials was that phycicians treating the pateints were allowed to use antithrombotics as needed in terms of therapy so the medical therapy group was actually comprised of both antiplatelets as well as antithrombotics. In the sub group analyses of these trials, PFO closure was noted to be significant superior to antiplatelet therapy alone. This observation led to two new trials which were recently published in NEMJ. These trials namely, CLOSE and GORE REDUCE trial used antiplatelets exclusively for comparison and thus produced results in favor of PFO closure. In short, based on these trials, PFO closure was found to have significant preventative strength in terms of recurrent strokes in patients with history of cryptogenic stroke. These findings can lead to changes in the guidelines when it comes to secondary prevention of stroke after a cryptogenic stroke episode ...

I had a PFO closure in Dec. 2007, and I just took plavix and asprin for 6 months. Ive been on 325 mg aspirin ever since, and proably will stay on it for life due to the stroke. I was fortunate also, and have no lasting affects from my stroke. However, I am having some issues with my heart possibly, which I incurred after my PFO closure. Just recently I found out my EKG is abnormal. No one had told me this before, but it doesnt match the EKG reading I had before the PFO procedure. My primary dr tells me not to worry, that it is ok, and normal for me, but Im still concerned. Especially since I think I feel a little different at times, like feeling my heart beat a time or two, and having some twinges of slight pain in different places. Ive had major tests and have been told Im ok in the past years. No tests in about 2 years. I was wondering if anyone else has had any side affects after the PFO closure ...

Swedish pioneered the PFO treatment, which involves using a special device - a tiny, double-umbrella apparatus - to seal a small congenital defect in the heart known as a patent foramen ovale (PFO). A PFO results from incomplete closure after birth in the atrial septum, which is a thin wall separating the upper chambers of the heart. It has been implicated as a potential cause for unexplained strokes in young adults. Repairing the defect may therefore reduce the patients future stroke risk.. Like PFO, an atrial septum defect (ASD) results from incomplete closure after birth in the wall between the left and right atria. About 7 percent of congenital heart defects fall into this category, and if the defect is large enough, oxygen-rich blood from the left atrium flows back into the right side of the heart and is pumped back to the lungs instead of to the rest of the body. This results in more work for the heart. Patients with large ASDs experience shortness of breath with physical exertion. ...
Its not uncommon for migraines to make you sensitive to light or leave jagged lines across your field of view. But some patients experience the visual symptoms of migraine without the headache. These "visual migraines" have recently been linked to a heart abnormality known as Patent Foramen Ovale (PFO).. PFO is a birth defect in which the walls between the two upper chambers of the heart dont close completely. An estimated 1 in 5 adults have PFO but since the defect doesnt typically cause symptoms, many people may not discover they have the defect until theyre struck with a transient ischemic attack, or a stroke lasting under 24 hours. Fortunately less than 1% of people with PFO experience these strokes as a result of this defect.. In patients with this disorder, the opening between the chambers of the heart can either be a right to left shunting or a left to right shunting. Right to left shunting is considered more dangerous than left to right, and has been associated with migraine with ...
A device for sealing a patent foramen ovale (PFO) in the heart is provided. The device includes a left atrial anchor adapted to be placed in a left atrium of the heart, a right atrial anchor adapted to be placed in a right atrium of the heart, and an elongate member adapted to extend through the passageway and connect the left and right atrial anchors. The right atrial anchor preferably includes a plurality of arms and a cover attached to the arms. The left atrial anchor preferably also includes a plurality of arms and preferably does not include a cover. Preferably, the elongate member has a first end fixedly connected to the left atrial anchor and a portion, proximal to the first end, passing through the right atrial anchor. Preferably, the elongate member is flexible.
The combination of trastuzumab and chemotherapy is considered the standard of care for patients with HER2-positive advanced gastric cancer on the basis of the results of a pivotal phase-III trial, which showed the efficacy of trastuzumab combined with cisplatin plus capecitabine or 5-FU as a first-line therapy [1]. The toxicity profile is mild, and no severe thromboembolisms such as cerebral infarction have been reported to date. In the present case, the patient presented with MCA embolism on the fourth day of the first cycle of chemotherapy with 5-FU, cisplatin, and trastuzumab. The mechanism underlying the cerebrovascular event caused by a chemotherapy regimen is likely multifactorial, including tumor microemboli and thromboembolism. The proposed mechanism of tumor embolization is invasion of the pulmonary veins, with or without left atrial invasion [2]. In rare cases, a tumor may invade the venous circulation and spread to the left side of the heart through a patent foramen ovale, leading to ...
