RESUMEN
RATIONALE: Transcatheter interventional closure therapy is the main treatment method for patent foramen ovale (PFO). However, occluder abscission is a serious complication in PFO interventional therapy. Thus, timely and effective management of the occluder detachment is crucial for improving patient prognosis. PATIENT CONCERNS: A 52-year-old female patient was admitted to the Department of Neurology mainly due to "right upper limb weakness for two days, which aggravated for eight hours." The patient had no history of any other diseases. DIAGNOSES: The patient was diagnosed with an atrial septal defect (foramen ovale type) and cerebral infarction. INTERVENTIONS AND OUTCOMES: The occluder abscission was successfully removed after several attempts with the help of the snare device. LESSONS: When the PFO occlusion device is detached, interventional treatment would lead to minimal trauma, fast postoperative recovery, and a definite therapeutic effect. Based on mastering the indications and standardizing the operational process, this is a safe and effective minimally invasive treatment method.

BACKGROUND: The patent foramen ovale (PFO) and interatrial block (IAB) are associated with cryptogenic stroke (CS). However, the role of the interaction between PFO and IAB in CS remains unclear. METHODS: This case-control study enrolled 256 patients with CS and 156 individuals without a history of stroke or transient ischemic attack. IAB was defined as P wave duration > 120 ms. PFO was evaluated by contrast transesophageal echocardiography, and classified as no-PFO, low-risk PFO and high-risk PFO. Multiplicative and additive interaction analysis were used to assess the interaction between PFO and IAB in CS. RESULTS: Multiplicative interaction analysis unveiled a significant interaction between IAB and low-risk PFO in CS (OR for interaction = 3.653, 95% CI, 1.115-12.506; P = 0.037). Additive interaction analysis indicated that 68.4% (95% CI, 0.333-1.050; P < 0.001) of the increased risk of CS related to low-risk PFO was attributed to the interaction with IAB. The results were robust in multivariate analysis. However, but no significant multiplicative or additive interaction was observed between IAB and high-risk PFO. When stratified by IAB, high-risk PFO was associated with CS in both patients with IAB (OR, 4.186; 95% CI, 1.617-10.839; P = 0.003) and without IAB (OR, 3.476; 95% CI, 1.790-6.750; P < 0.001). However, low-risk PFO was only associated with CS in patients with IAB (OR, 2.684; 95% CI, 1.007-7.149; P = 0.048) but not in those without IAB (OR, 0.753; 95% CI, 0.343-1.651; P = 0.479). CONCLUSION: The interaction between IAB and PFO might play an important role in CS, particularly in cases with low-risk PFO.

OBJECTIVE: Deep vein thrombosis (DVT) is discussed as a source of embolism for cerebral ischemia in the presence of patent foramen ovale (PFO). However, previous studies reported varying rates of DVT in stroke patients, and recommendations for screening are lacking. This study aimed to characterize patients with stroke or transient ischemic attack (TIA) and concomitant PFO and explore the rate of DVT and associated parameters. METHODS: Medical records were screened for patients with stroke or TIA and echocardiographic evidence of PFO. Concomitant DVT was identified according to compression ultrasonography of the lower limbs. A variety of demographic, clinical, and laboratory parameters, the RoPE and Wells scores were compared between patients with and without DVT. RESULTS: Three-hundred-thirty-nine patients (mean age 61.2 ± 15.4 years, 61.1% male) with stroke or TIA and PFO, treated between 01/2015 and 12/2020, were identified. Stroke and TIA patients did not differ for demographic and vascular risk factors. DVT was found in 17 cases out of 217 (7.8%) with compression ultrasonography. DVT was associated with a history of DVT, cancer, previous immobilization, calf compression pain, calf circumference difference, and a few laboratory abnormalities, e.g., increased D-dimer. A multivariate regression model with stepwise backward selection identified the Wells score (odds ratio 35.46, 95%-confidence interval 4.71-519.92) as a significant predictor for DVT. CONCLUSION: DVT is present in a relevant proportion of patients with cerebral ischemia and PFO, which needs to be considered for the individual diagnostic workup. The Wells score seems suitable for guiding additional examinations, i.e., compression ultrasonography.

OBJECTIVE: This study aims to evaluate the application value of contrast-enhanced transthoracic echocardiography (cTEE) in the diagnosis of patent foramen ovale (PFO) under different states of stimulation, with the goal of enhancing the accuracy and efficiency of PFO diagnosis. METHODS: This research consecutively enrolled patients suspected of having PFO from October 2022 to February 2024, presenting primary clinical symptoms such as unexplained syncope, headache, dizziness, and stroke. Patients underwent standard transthoracic echocardiography (TTE) and cTEE under three different states of stimulation (resting state, coughing, and Valsalva maneuver). Based on the presence of microbubbles in the left heart and their initial appearance time, patients were classified into PFO and control groups, with further diagnostic confirmation via transesophageal echocardiography (TEE) or foramen ovale closure procedures. RESULTS: The study results revealed significant differences between the PFO and control groups regarding age (p = 0.034) and headache symptoms (p = 0.001). In the PFO group, TTE showed a higher positivity rate both at rest and during coughing, highlighting the association between PFO and specific clinical symptoms. The number of microbubbles observed during TTE increased significantly under various stimulation states, particularly during the Valsalva maneuver (p < 0.05). This increase became more pronounced as the duration of the maneuver was extended, underscoring the differential response of PFO patients under varied physiological testing conditions, especially during prolonged Valsalva maneuvers. CONCLUSION: The study confirms the significant value of cTEE in diagnosing PFO under different stimulation states, particularly emphasizing the application of the Valsalva maneuver to significantly improve the sensitivity and specificity of PFO detection. Thus, incorporating cTEE examinations under various stimulation states holds significant clinical importance for enhancing the accuracy and efficiency of PFO diagnosis.

The foramen ovale plays a vital role in sustaining life in-utero; however, a patent foramen ovale (PFO) after birth has been associated with pathologic sequelae in the systemic circulation including stroke/transient ischemic attack (TIA), migraine, high altitude pulmonary edema, decompression illness, platypnea-orthodeoxia syndrome (POS) and worsened severity of obstructive sleep apnea. Importantly, each of these conditions is most commonly observed among specific age groups: migraine in the 20 to 40s, stroke/TIA in the 30-50s and POS in patients >50 years of age. The common and central pathophysiologic mechanism in each of these conditions is PFO-mediated shunting of blood and its contents from the right to the left atrium. PFO-associated pathologies can therefore be divided into (1) paradoxical systemic embolization and (2) right to left shunting (RLS) of blood through the PFO. Missing in the extensive literature on these clinical syndromes are mechanistic explanations for the occurrence of RLS, including timing and the volume of blood shunted, the impact of age on RLS, and the specific anatomical pathway that blood takes from the venous system to the left atrium. Visualization of the flow pattern graphically illustrates the underlying RLS and provides a greater understanding of the critical flow dynamics that determine the frequency, volume, and pathway of flow. In the present review, we describe the important role of foramen ovale in in-utero physiology, flow visualization in patients with PFO, as well as contributing factors that work in concert with PFO to result in the diverse pathophysiological sequelae.

BACKGROUND: Young patients suffering from cryptogenic stroke alongside a patent foramen ovale (PFO) are often considered for percutaneous device closure to reduce the risk of stroke recurrence. Residual right-to-left shunt after device closure may persist in approximately a quarter of the patients at 6 months, and some may close at a later time point. This study aimed to assess the prevalence and persistence of residual right-to-left shunt after percutaneous PFO closure. METHODS: Consecutive patients undergoing transoesophageal echocardiography-guided PFO closure for cryptogenic stroke between 2006 and 2021, with echocardiographic follow-up including contrast bubble study and Valsalva manoeuvre, were enrolled. Follow-up transthoracic echocardiography was performed at 6 months and repeated at 12 months in case of residual right-to-left shunt. Primary outcomes included the prevalence and grade of residual right-to-left shunt at 6 and 12 months after percutaneous PFO closure. RESULTS: 227 patients were included with a mean age of 43±11 years and 50.2% were women. At 6-month follow-up, 72.7% had no residual right-to-left shunt, 12.3% small residual right-to-left shunt, 6.6% moderate residual right-to-left shunt and 8.4% large residual right-to-left shunt. At 12-month follow-up, the presence of residual right-to-left shunt in all patients was 12.3%, of whom 6.6% had small residual right-to-left shunt, 2.6% had moderate residual right-to-left shunt and 3.1% had large residual right-to-left shunt. CONCLUSIONS: Residual right-to-left shunts are common at 6 months after percutaneous closure of PFO. However, the majority are small and two-thirds of residual right-to-left shunts achieve complete closure between 6 and 12 months.

A 15-year-old male patient presented with a 3-year history of recurrent dizziness and headaches and was initially diagnosed with patent foramen ovale. A transcatheter closure procedure was planned and conducted under general anesthesia, utilizing ultrasound guidance through the femoral vein. Preadmission echocardiography confirmed the presence of a patent foramen ovale. However, further investigation with transesophageal echocardiography (TEE) performed under general anesthesia, revealed that the observed atrial septal anomaly was not a patent foramen ovale. Instead, real-time TEE identified it as the left atrial opening of the coronary vein. Subsequent detailed TEE tracking confirmed a rare case of coronary sinus ostium atresia with left atrial reflux of the coronary vein, leading to a significant revision of the initial diagnosis and planned treatment.

BACKGROUND AND AIMS: Transjugular intrahepatic portosystemic shunt (TIPS) is an established procedure for the treatment of several complications of portal hypertension (PH), including non-neoplastic portal vein thrombosis (PVT). Selection criteria for TIPS in PVT are not yet well established. Despite anecdotal, cases of thromboembolic events from paradoxical embolism due to the presence of patent foramen ovale (PFO) after TIPS placement have been reported in the literature. Therefore, we aimed at describing our experience in patients with non-neoplastic splanchnic vein thrombosis (SVT) who underwent TIPS following PFO screening. METHODS: We conducted a single-centre retrospective study, including consecutive patients who underwent TIPS for the complications of cirrhotic and non-cirrhotic portal hypertension (NCPH) and having SVT. RESULTS: Of 100 TIPS placed in patients with SVT, 85 patients were screened for PFO by bubble-contrast transthoracic echocardiography (TTE) with PFO being detected in 22 (26%) cases. PFO was more frequently detected in patients with non-cirrhotic portal hypertension (NCPH) (23% in the PFO group vs. 6% in those without PFO, p = .04) and cavernomatosis (46% in the PFO group vs. 19% in those without PFO, p = .008). Percutaneous closure was effectively performed in 11 (50%) after multidisciplinary evaluation of anatomical and clinical features. No major complications were observed following closure. CONCLUSIONS: PFO screening and treatment may be considered feasible for patients with SVT who undergo TIPS placement.

BACKGROUND: Limited data are available on transcatheter patent foramen ovale (PFO) closure outcomes in the elderly. AIMS: Through this study, we aimed to determine the incidence and predictors of adverse events (recurrent cerebrovascular events [CVE] and atrial fibrillation [AF]) post-PFO closure in older patients with cryptogenic events. METHODS: This multicentre international study included patients over 60 years undergoing PFO closure for cryptogenic thromboembolic events. A dedicated database compiled baseline, procedural, and follow-up data. Competing risk and adjusted outcome predictor analyses were conducted. RESULTS: A total of 689 patients were included (median age 65 years, 41.2% female, mean Risk of Paradoxical Embolism [RoPE] score 4.5). The procedural success rate was 99.4%. After a median follow-up of 2 (interquartile range 1-5) years, 66 patients (9.6%) had died. CVE and stroke rates were 1.21 and 0.55 per 100 patient-years, respectively. Diabetes (hazard ratio [HR] 3.89, 95% confidence interval [CI]: 1.67-9.07; p=0.002) and atrial septal aneurysm (ASA; HR 5.25, 95% CI: 1.56-17.62; p=0.007) increased the CVE risk. New-onset AF occurred at a rate of 3.30 per 100 patient-years, with 51.3% within one month post-procedure. Older age (HR 1.05 per year, 95% CI: 1.00-1.09; p=0.023) and the absence of hypertension (HR 2.04, 95% CI: 1.19-3.57; p=0.010) were associated with an increased risk of AF. CONCLUSIONS: Older patients undergoing PFO closure had a relatively low rate of CVE and new-onset AF after a median follow-up of 2 years. The presence of diabetes, ASA, and a more advanced age determined an increased risk of adverse clinical events. These factors may be considered in the clinical decision-making process regarding PFO closure in this challenging population.

A patient presenting with acute ischemic stroke associated with patent foramen ovale (PFO) had concurrent deep vein thrombosis, pulmonary embolism, and new-onset atrial fibrillation. Upon initiation of anticoagulation therapy, the patient developed hemorrhagic transformation of the stroke. The patient's multiple potential sources of embolic stroke were treated with concomitant left atrial appendage occlusion and PFO closure through the PFO, made possible by using the Steerable Amulet Sheath under 3D-intracardiac echocardiography guidance.

BACKGROUND: Patent foramen ovale (PFO)-associated stroke is diagnosed more frequently in young patients with infrequent vascular risk factors and embolic appearing infarcts. The risk of paradoxical embolism (RoPE) score is used to identify PFO-associated stroke. Patients with symptomatic carotid artery web (CaW) share a very similar risk profile and these lesions are frequently overlooked. In this study, we evaluate the RoPE score profile in patients with suspected symptomatic CaW. METHODS: Retrospective analysis of prospectively collected data of patients with symptomatic CaW as the presumed cause of stroke presenting to 2 comprehensive stroke centers from 2014 to 2021. CaW was diagnosed using computed tomography angiography (CTA) of the neck & head. Shunt study was done using a transthoracic, transesophageal, and/or transcranial-Doppler with bubbles. RoPE score ≥7 was considered high. RESULTS: Seventy-five patients had stroke from a symptomatic ipsilateral CaW. Mean age was 49.7±11.2 years and 74.7â¯% were females. Median RoPE score was 7 [5-8], and 52.0â¯% had a high RoPE score. PFO was detected in 13.3â¯% of the patients and 20.5â¯% within the high RoPE score group. Ten percent of the cases would have been misclassified as PFO-associated strokes based on RoPE score. CONCLUSION: High RoPE scores were observed in the majority of patients with CaW-attributed stroke, and it should not be used to differentiate CaW- versus PFO-associated stroke. Careful extracranial internal carotid artery evaluation for CaW is warranted in cryptogenic strokes, including in PFO positive patients before defining stroke etiology.

BACKGROUND: The morphology of a patent foramen ovale (PFO) with a high-risk for cryptogenic ischemic stroke (CS) is an important factor in the selection of patients for transcatheter closure, but the morphological features of PFO in older patients with a history of CS are less known because the most data are obtained from younger patients. METHODS AND RESULTS: The study included 169 patients who had a history of CS and PFO. The prevalence of high-risk morphologies of PFO assessed by transesophageal echocardiography was compared between patients aged ≥60 years and patients aged <60 years. We also assessed the presence of septal malalignment of PFO on the aortic wall. The probability of CS due to PFO was evaluated using the PFO-Associated Stroke Causal Likelihood classification system. Patients aged ≥60 years had a significantly higher prevalence of atrial septal aneurysm than patients aged <60 years. The prevalence of large right-to-left shunt, long-tunnel of PFO, or Eustachian valve or Chiari's network was similar between patients aged ≥60 years and <60 years. Septal malalignment was observed more frequently in patients aged ≥60 years than in those <60 years old. Nearly 90% of patients aged ≥60 years were classified as 'possible' in the PFO-Associated Stroke Causal Likelihood classification system. CONCLUSIONS: High-risk morphologies of PFO are common in older patients with a history of CS, as well as in younger patients.

Racial and ethnic differences in the prevalence of patent foramen ovale have been suggested, but there are insufficient data to confirm the situation. Studies have also not investigated detailed morphological changes in the fossa ovalis by age. This study therefore aimed to clarify the characteristics of the fossa ovalis and determine the frequency of patent foramen ovale in Japanese people, using materials from forensic autopsies. A total of 359 hearts were obtained during forensic autopsies (from 223 males and 136 females, aged from 0 to 94 years). Overall, prevalence of patent foramen ovale was 12.5%, but it was significantly higher among those under 20 years old (66.7% in males, 38.5% in females). The area of the fossa ovalis linearly increased with age in both sexes. The prevalence of patent foramen ovale was lower in Japanese adults than previously found in either White or Black people. The ratio of the area of the fossa ovalis to the heart weight was nearly constant.
