Project description:BackgroundThe presence of a patent foramen ovale (PFO) is associated with several medical conditions, including cryptogenic left circulation thromboembolism. PFO closure was demonstrated to reduce recurrent ischaemic stroke in patients with prior cryptogenic stroke. The presence of an inferior vena cava filter (IVCF), however, may impede a transfemoral PFO closure procedure.Case summaryWe describe the case of a 50-year-old man with a PFO suffering from ischaemic stroke from paradoxical thromboembolism originating from deep vein thrombosis and requiring an IVCF. After deep vein thrombosis resolution, due to the high risk of stroke recurrences, the patient was recommended PFO closure. IVCF retrieval by the interventional radiologist was first attempted but failed. A transfemoral PFO closure procedure was thus endeavoured with the IVCF in place and was successful. The patient was then discharged in good clinical status and no stroke recurrences were reported at 5 months follow-up.DiscussionAlbeit an IVCF provides benefit in patients with recurrent thromboembolic events despite adequate anticoagulation therapy, its presence may hinder interventional procedures necessitating delivery systems to advance through the inferior vena cava. We reported on a successful PFO closure procedure via a femoral venous access in a patient with an IVCF in place, thus demonstrating the feasibility of advancing delivery systems through an IVCF. As interventional procedures requiring the advancement of delivery systems through the inferior vena cava are becoming increasingly common, the feasibility of IVCF crossing with catheters and delivery systems alike paves the way for novel interventional possibilities.

Project description:In patients with challenging femoral vein anatomy, transcatheter patent foramen ovale (PFO) closure can be safely and effectively be done through the jugular veins guided by ICE from the arm. This novel technique can potentially save resources (anesthesia and TEE) and provide an option for patients without a femoral option.

Project description:Patent foramen ovale (PFO) is a common abnormality affecting between 20% and 34% of the adult population. For most people, it is a benign finding; however, in some people, the PFO can open widely to enable paradoxical embolus to transit from the venous to arterial circulation, which is associated with stroke and systemic embolisation. Percutaneous closure of the PFO in patients with cryptogenic stroke has been undertaken for a number of years, and a number of purpose-specific septal occluders have been marketed. Recent randomised control trials have demonstrated that closure of PFO in patients with cryptogenic stroke is associated with reduced rates of recurrent stroke. After a brief overview of the anatomy of a PFO, this article considers the evidence for PFO closure in cryptogenic stroke. The article also addresses other potential indications for closure, including systemic arterial embolisation, decompression sickness, platypnoea-orthodeoxia syndrome and migraine with aura. The article lays out the pre-procedural investigations and preparation for the procedure. Finally, the article gives an overview of the procedure itself, including discussion of closure devices.

Project description:Patent foramen ovale (PFO) concerns nearly a quarter of the general population and incidence may reach up to 50% in patients with cryptogenic stroke. Recent randomized clinical trials confirmed that percutaneous closure of PFO-related stroke reduces the risk of embolic event recurrence. PFO also comes into play in other pathogenic conditions, such as migraine, decompression sickness or platypnea-orthodeoxia syndrome, where the heterogeneity of patients is high and evidence for closure is less well-documented. In this review, we describe the current indications for PFO percutaneous closure and the remaining challenges, and try to provide future directions regarding the technique and its indications.

Project description:Background and purposeWe sought to evaluate the real-world rate of safety outcomes after patent foramen ovale (PFO) closure in patients with ischemic stroke or transient ischemic attack (TIA).MethodsWe performed a retrospective cohort study using administrative claims data on all hospitalizations from 2005 to 2013 in New York, California, and Florida. Using International Classification of Diseases, Ninth Revision, Clinical Modification codes, we identified patients who underwent percutaneous transcatheter PFO closure within 1 year of ischemic stroke or TIA. Our outcome was an adverse event occurring during the hospitalization for PFO closure, defined as in prior studies as atrial fibrillation or flutter, cardiac tamponade, pneumothorax, hemothorax, a vascular access complication, or death. Crude rates were reported with exact confidence intervals.ResultsWe identified 1887 patients who underwent PFO closure after ischemic stroke or TIA. The rate of any adverse outcome during the hospitalization for PFO closure was 7.0% (95% confidence interval [CI], 5.9%-8.2%). Rates of adverse outcomes varied by age and type of preceding cerebrovascular event. In patients >60 years of age, the rate of adverse outcomes was 10.9% (95% CI, 8.6%-13.6%) versus 4.9% (95% CI, 3.8%-6.3%) in patients ≤60 years of age. The rate of adverse outcomes was 9.9% (95% CI, 7.3%-12.5%) in patients with preceding ischemic stroke versus 5.9% (95% CI, 4.7%-7.1%) after TIA.ConclusionsApproximately 1 in 14 patients who underwent percutaneous transcatheter PFO closure after ischemic stroke or TIA experienced a serious periprocedural adverse outcome or death. The risk of adverse outcomes was highest in older patients and in those with preceding ischemic stroke.

Project description:Proof that percutaneous closure of the patent foramen ovale (PFO) is superior to medical treatment is still incomplete. Paradoxical embolism is a rare event occurring over decades rather than years. None of the 4 randomized trials published carried enough patients or was followed up for long enough to reach superiority endpoints. All data, however, point to a benefit of PFO closure. Free wall erosion (exceedingly rare) and triggering of atrial fibrillation (in about 1% of patients) are the only noteworthy complications. They are outweighed by the supposedly prevented events of paradoxical embolisms, such as stroke, transient ischemic attacks, myocardial infarctions, or other systemic embolisms. Medical treatment with perhaps the exception of lifelong oral anticoagulation provides less protection. During a 10-year follow-up of a comparative study the annual mortality was significantly lower in the patients with PFO closure (0.4%) than in those with medical treatment (1.1%, P < 0.03). PFO closure can be accomplished in less than 1 hour with immediate resumption of physical activity. It represents thus a kind of mechanical vaccination.

Project description:Background Transcatheter closure of patent foramen ovale (PFO) has reduced the risk of recurrent stroke in patients with cryptogenic strokes in randomized clinical trials. Whether PFO closure in clinical practice is associated with similar benefit remains unknown. Methods and Results We identified patients with PFO and a history of ischemic stroke or transient ischemic attack who were treated with PFO closure or medical therapy in the OptumLabs database. The primary end point was recurrent ischemic stroke or systemic embolization. Secondary outcomes included mortality, all stroke, transient ischemic attack, and major bleeding. A total of 6668 propensity-matched patients were included (PFO closure n=4111; medical therapy n=2557). The incidence of stroke or systemic embolization per 100 person-years was 2.38 after PFO cohort and 2.99 with medical therapy (hazard ratio [HR], 0.85 [95% CI, 0.68-1.05], P=0.13). Mortality was lower in the PFO closure cohort (1.78 versus 2.59 per 100 person-years: HR, 0.69 [95% CI, 0.55-0.87], P=0.002). Falsification end points showed that this difference is unlikely to be completely explained by residual confounders. There were no significant differences between the groups in secondary end points including intracranial hemorrhage and major bleeding except for an increase in nonintracranial hemorrhage bleeding among patients treated with oral anticoagulation (1.42 versus 2.16 per 100 person-years: HR, 0.69 [95% CI, 0.48-0.99], P=0.043). The main end point was consistent in subanalyses including patients <60 years of age, patients with prior stroke, and those treated after the publication of the positive PFO trials in 2017. Conclusions In contemporary US practice, PFO closure is not associated with lower rates of recurrent ischemic stroke or systemic embolization compared with medical therapy. Potential reasons for this discrepancy warrant further investigation.
