Project description:A 35 year old man with a history of transient ischaemic attack and atrial septal aneurysm underwent percutaneous closure of a patent foramen ovale (PFO) with a transcatheter device. After the procedure the patient developed effort angina not present previously. Transoesophageal echocardiography confirmed the absence of residual shunt but showed an abnormal linear image running behind the aortic root. Magnetic resonance imaging detected an anomalous origin of the circumflex coronary artery from the right coronary sinus. The anomalous artery was located between the aortic root and the PFO closing device, causing coronary insufficiency. This report describes a rare complication of transcatheter PFO closure.

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:BackgroundThe exact incidence and predictors of new-onset atrial fibrillation (AF) after percutaneous closure of patent foramen ovale (PFO) are unknown.ObjectiveWe sought to find post-procedural AF incidence rates and differences due to different screening strategies and devices.MethodsA systematic search was conducted in Cochrane, MEDLINE and EMBASE. Controlled trials fulfilling the inclusion criteria were included into this meta-analysis. The incidence of new-onset AF was the primary outcome. Further parameters were surveillance strategy, device type, AF treatment and neurological events. New AF was determined as early onset within one month after implantation and late thereafter.Results8 controlled trials and 16 cohort studies were eligible for quantitative analysis. 7643 patients received percutaneous PFO closure after cryptogenic stroke or transient ischaemic attack, 117 with other indications, whereas 1792 patients formed the control group. Meta-analysis of controlled trials showed an AF incidence of 5.1% in the interventional and 1.6% in the conservative arm, respectively (OR 3.17, 95% CI 1.46-6.86, P = 0.03, I2 = 55%). 4.7% received high-quality surveillance strategy with Holter-ECG or Loop recorder whereby AF incidence was overall higher compared to the low-quality group with 12-lead ECG only (3.3-15% vs. 0.2-4.3%). Heterogeneous results on time of AF onset were found, limited by different follow-up strategies. CardioSEAL and Starflex seemed to have higher AF incidences in early and late onset with 4.5% and 4.2%, respectively.ConclusionPercutaneous PFO closure led to higher AF post-procedural incidence compared to the conservative strategy. Heterogeneity in surveillance and follow-up strategy limited the generalizability.Trial registrationRegistered on PROSPERO (CRD42022359945).

Project description:Background Percutaneous closure of the patent foramen ovale (PFO) is primarily guided by fluoroscopy in the catheter room, during which procedure both the guidewire and sheath need to pass through the PFO. We performed PFO closure using a transesophageal echocardiography (TEE)-guided approach and only the sheath was passed through the PFO during the procedure. This study aimed to evaluate the feasibility and safety of PFO closure using this technique. Methods A retrospective observational study was performed. A total of 117 consecutive adult patients underwent percutaneous PFO closure without fluoroscopy, under the sole guidance of TEE in our hospital between December 2018 and December 2021. The data of each patient consisted of preoperative, operative, and postoperative variables collected. The primary outcome is that the occluder was successfully released. The secondary outcomes included perioperative and follow-up transthoracic echocardiography (TTE), Headache impact test-6 (HIT-6) score and clinical symptoms. Results Transvenous PFO closure under TEE guidance was successful in all cases. The sample consisted of 93 females and 24 males with an average age of 42.3±7.8 years. There were 28 patients with preoperative cerebral infarction [Risk of Paradoxical Embolism (RoPE) score >6 points] and 89 patients with migraine. All patients underwent a preoperative TEE to confirm the presence of PFO, and contrast-enhanced transcranial Doppler (c-TCD) acoustic contrast suggested grades 3 to 4. The average time of surgery for patients (puncture to removal of the sheath) was 32 minutes. Three cases of vagus nerve reflex manifestations during surgery and two cases of transient ventricular arrhythmia all improved after symptomatic treatment. There were no instances of metal allergy, hemolysis, or other acute vascular procedural complications. For all 89 patients with migraine, significant relief or resolution was achieved during the first six-month follow-up (P<0.001). Conclusions As a monotherapy, percutaneous closure of PFO guided by TEE where only the sheath passes through the PFO during the operation is an effective procedure with a high success rate and a low complication rate.

Project description:BackgroundThe benefit of patent foramen ovale closure (PFOC) ≤9 months after a cryptogenic stroke has been demonstrated in several randomised clinical trials. There is, however, insufficient data to support PFOC in non-recent cryptogenic strokes.AimsThe objective of the study was to evaluate the effectiveness of PFOC in relation to the time since the patient's most recent cryptogenic cerebrovascular event (CVE) or systemic embolism (SE).MethodsWe conducted a multicentre, retrospective cohort study with international participation, to assess the results of an early closure (EC, <9 months) for secondary prevention versus a delayed closure (DC, ≥9 months). Recurrence of CVE/SE following PFOC was evaluated as the primary endpoint.Results496 patients were included (65% in the EC and 35% in the DC group). With the exception of a larger defect size in the DC group (tunnel width 6 (4-14) vs 12 (6-16) mm, p=0.005), similar clinical and echocardiographic baseline features were observed between the groups. No differences were observed regarding the type of devices used for PFOC, procedural success rate (99.4 in EC vs 98.8% DC group) and periprocedural complications (2.1% vs 0.8%). Median follow-up was 2.0 (1.2-4.2) years in the whole study population. Recurrence of CVE/SE (3.9% vs 2.6%, p=0.443), death (1.4% vs 1.0%, p=0.697), residual shunt 12 months after PFOC, or antithrombotic treatment strategy were comparable in both groups during follow-up. A subanalysis comparing very delayed PFOC (≥24 months) also showed no differences in recurrence (4.2% in the <24-month vs 3.4% in the ≥24-month group, p=0.770).ConclusionPatients undergoing PFOC before and after 9 months after the index event had a comparable recurrence rate of CVE/SE. These findings suggest that PFOC might be recommended in cryptogenic CVE/SE which are more remote than 9 months.

Project description:IntroductionThe presence of patent foramen ovale (PFO) is considered a possible cause for cryptogenic stroke. The mechanism underlying the ischaemic neurological events in the presence of PFO has not been firmly established. The purpose of this study was to compare: (1) the mean platelet volume levels in PFO patients with and without a cryptogenic stroke, and (2) pre- and post-procedural mean platelet volumes (MPV) in patients undergoing percutaneous PFO closure.MethodsSixteen PFO patients undergoing percutaneous closure to prevent recurrent ischaemic events and 15 asymptomatic patients with PFO were enrolled in the study. Mean platelet volume was compared between patients with and without a history of stroke. We also compared pre- and post-procedural MPV levels in patients undergoing percutaneous PFO closure.ResultsMean platelet volume, which is a marker for platelet activity, was similar in PFO patients with and without stroke (9.34 ± 1.64 vs 9.1 ± 1.34 fl; p = 0.526). Interestingly, MPV decreased significantly after percutaneous closure compared to pre-procedural levels (9.34 ± 1.64 vs 8.3 ± 1.12 fl; p = 0.001).ConclusionOur findings suggest interatrial communication through a PFO may be related to increased MPV and increased platelet activity.

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.
