OBJECTIVES: The purpose of this study is to compare the long-term outcomes of patent foramen ovale (PFO) closure using angiography or transesophageal echocardiography as procedural guidance. BACKGROUND: The interventional treatment is emerging as a safe and efficient option for patients with high likelihood of PFO-related cryptogenic stroke and high risk of recurrence. The "gold-standard" guidance technique remains an issue. METHODS: Two cohorts of patients undergoing PFO closure for cryptogenic stroke in two catheterization laboratories of the same institution, using similar inclusion criteria but different guidance, were compared with propensity score matching...

OBJECTIVE: Percutaneous closure of patent foramen ovale (PFO) and atrial septal defect (ASD) is routinely performed under general anesthesia or deep sedation and use of transesophageal (TEE) or intracardiac echocardiography, incurring longer duration and higher cost. We have used a simplified, economical, fluoroscopy-only guided approach with local anesthesia, and herein report our data. METHODS: The study includes 112 procedures in 110 patients with PFO (n=75) or ASD (n=35), with use of an Amplatzer occluder, heparin and prophylactic antibiotics...

OBJECTIVE: Idiopathic Parkinson's disease (IPD) is the second most common neurodegenerative disorder, often complicated by dementia. Cardiovascular risk factors and spontaneous cerebral emboli (SCE) are strongly associated with Alzheimer's (AD) and vascular dementia (VaD). We measured SCE in the middle cerebral artery and arterial wall volume in the extracranial arteries in patients with IPD and controls, and explored the relationships with structural and physiological MRI brain neurovascular measures...

In this article, we have demonstrated a method for producing hollow particles and microcapsules using oil droplets consisting of hydrocarbon oil (styrene) and fluorocarbon oil (perfluoro-n-octane, PFO) in aqueous surfactant (sodium dodecylsulfate, SDS) solutions. Since fluorocarbon oils are immiscible with hydrocarbon oils, the two oils are separated. Emulsions are prepared by stirring styrene/PFO/aqueous SDS solution mixtures at 80 °C. The type of emulsions and the morphology of droplets in the emulsions are observed by light microscope and scanning confocal fluorescence microscope...

OBJECTIVE: To describe the early hemodynamic changes after fetal aortic valvuloplasty (FAV) for evolving hypoplastic left heart syndrome due to mid-gestational aortic stenosis and to assess whether these early changes predict biventricular (BiV) circulation at neonatal discharge. METHOD: We retrospectively reviewed all technically successful FAV cases resulting in live birth between 2000 and 2015 (n=93, 45% BiV circulation at neonatal discharge). Paired testing methods were used to compare pre- and post-intervention measures of left ventricular hemodynamics...

AIMS: Despite the widespread use of percutaneous closure of patent foramen ovale (PFO) in patients after a cryptogenic stroke, little is known about its impact on health-related quality of life (HRQoL). The aim of this study was to assess HRQoL in these patients compared to PFO patients not considered candidates for percutaneous closure, and to a normal population. METHODS AND RESULTS: A total of 402 patients with cryptogenic stroke or transient ischaemic attack (TIA) who had been referred to our center for PFO closure were invited to a long-term clinical follow-up (mean follow-up 5...

A paradoxical embolism is defined as a systemic arterial embolus due to passage of a venous thrombus through a right to left shunt. We describe a case of acute cerebral vascular accident (CVA), right subclavian arterial embolus, and pulmonary emboli in the setting of a large patent foramen ovale (PFO). A 74-year-old woman with multiple comorbidities presented to the emergency department with acute onset of shortness of breath, weakness, and right arm pain. She was found to have bilateral pulmonary emboli, left CVA, and a right subclavian arterial embolus on computed tomography (CT)...

RATIONALE: The differential diagnosis of acute chest pain is very important, and can sometimes be challenging. Related diseases share a number of risk factors, and occasionally, 1 condition causes another disease to develop. PATIENT CONCERNS: We described a 59-year-old man who presented to emergency department complaining of chest pain. DIAGNOSES: He was suffered acute myocardial infarction (MI) and pulmonary embolism (PE) simultaneously. INTERVENTIONS: Dual antiplatelet therapy, statin, and low molecular weight heparin were administrated during his stay...

BACKGROUND: Transesophageal echocardiography (TEE) plays a unique role in transcatheter closure of atrial septal defects (ASD) and patent foramen ovale (PFO). However, problems such as the need for general anesthesia, possible trauma from endotracheal intubation, presence of "blind spots," and occasional inadequate imaging of some cardiac structures have necessitated better imaging techniques. Our study aimed to compare the findings of TEE during the initial diagnostic examination with those from intracardiac echocardiography (ICE) acquired during the interventional procedure...

PURPOSE: Hip and knee arthroplasty surgeries are associated with embolism of materials such as air, cement, and fat. Patent foramen ovale (PFO) is a common congenital cardiac condition that has been reported to lead to paradoxical embolism. This observational study aimed to investigate if the presence of a PFO was associated with an increased risk of postoperative delirium in patients undergoing primary elective hip or knee arthroplasties. METHOD: This was a prospective cohort study at a tertiary teaching hospital...

A series of recent acute blindness cases following non-complicated retinal detachment surgery caused the release of several health alerts in Spain. The blindness was attributed to certain lots of perfluoro-octane (PFO; a volatile and transient medical device). Similar cases have been reported in other countries. This has raised questions regarding the validity of cytotoxicity test methods currently used to certify the safety of PFO lots. The tests were performed according to the International Organization for Standardization (ISO) norms, using the extract dilution method or the indirect contact method as applied to L929 cells, a line derived from mouse fibroblasts...

Paradoxical embolization is the most commonly proposed mechanism for ischemia in patients with patent foramen ovale (PFO). We hypothesize that these patients can experience a microembolic genesis of cochleovestibular dysfunction, with a peripheral vestibular syndrome and simultaneous cochlear signs. Hence, we report the first case in literature associating PFO and acute transitory audiovestibular loss, which occurred in a male who had had an ischemic mesencephalic stroke several months ago. The patient's history and duration of the current event of less than 24 hours following complete functional recovery without any damage highlight the vascular cause in cochleovestibular dysfunction and support the existence of a clinical entity that could be named "cochleovestibular transient ischemic attack"...

BACKGROUND: PFO is more common in cases with cryptogenic stroke compared to cases with no stroke or stroke of identified etiology. Several randomized controlled trials (RCTs) comparing PFO closure with medical therapy have been published with controversial findings. METHODS: PubMed, Embase and Cochrane library databases were searched for RCT comparing PFO closure with medical therapy including antiplatelet therapy (aspirin or clopidogrel or combination) or anticoagulation...

INTRODUCTION: Patient foramen ovale (PFO) is a common and often incidental intraoperative finding during lung transplantation (LTx). We sought to characterize the potential outcomes related to the decision-making of whether the PFO was repaired or left unrepaired. METHODS: We retrospectively evaluated bilateral LTx recipients between 2005 and 2015 from our prospective database. Incidence of postoperative stoke, 90-day mortality, and overall survival was compared between the PFO-positive and PFO-negative groups, and secondly compared between repaired PFO (rPFO) and non-repaired PFO (nrPFO) groups...

BACKGROUND: Little is known regarding changes in treatment effect over time associated with patent foramen ovale (PFO) closure among patients with embolic stroke of unknown origin. METHODS: We reconstructed Kaplan-Meier curves for stroke from individual randomized trials comparing PFO closure vs. medical therapy among patients with embolic stroke. Random effects Cox-regression analyses were performed in order to estimate hazard ratios (HRs) with 95% confidence intervals (95%CIs)...

An electrochemiluminescencent (ECL) biosensor was designed for the determination of insulin using a novel ECL resonance energy transfer (ECL-RET) strategy. In this strategy, carboxyl poly(9,9-dioctyfluorenyl-2,7-diyl) dots (PFO dots) were worked as ECL donor and 3,4,9,10-perylenetetracar-boxylic acid (PTCA) exploited as ECL acceptor, and hydrogen peroxide (H2O2) employed as the coreactant. The ECL donor and ECL acceptor were separately labeled with primary antibody (Ab1) and secondary antibody (Ab2), forming a sensing interface to the analyte target, insulin...
