Front Public Health 2022; 10:1016854. [PMID: 36407985 PMCID: PMC9669480 DOI: 10.3389/fpubh.2022.1016854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Accepted: 09/13/2022] [Indexed: 11/06/2022] Open
Abstract
Background In 2019, there were 28. 76 million patients with stroke in China, with ~25% of them suffering from cryptogenic stroke (CS). Patent foramen ovale (PFO) is related to CS, and PFO closure can reduce recurrent stroke. To date, no study has investigated the cost-effectiveness of PFO closure vs. medical therapy among such populations in China. Methods A Markov model with a cycle length of 3 months was established to compare the 30-year cost-effectiveness of PFO closure and medical therapy. The transition probability of recurrent stroke was derived from the RESPECT study, and the costs and utility were obtained from domestic data or studies conducted in China. The primary outcome of this study was the incremental cost-effectiveness ratio (ICER), which represents the incremental cost per quality-adjusted life year (QALY). PFO closure was considered cost-effective if the ICER obtained was lower than the willingness-to-pay (WTP) threshold of 37,654 USD/QALY; otherwise, PFO closure was regarded as not being cost-effective. One-way and probabilistic sensitivity analyses were performed to test the robustness of the results. Results After a simulation of a 30-year horizon, a cryptogenic stroke patient with PFO was expected to have QALY of 13.15 (15.26 LY) if he received PFO closure and a corresponding value of 11.74 QALY (15.14 LY) after medical therapy. The corresponding costs in both cohorts are US $8,131 and US $4,186, respectively. Thus, an ICER of 2783 USD/QALY and 31264 USD/LY was obtained, which is lower than the WTP threshold. One-way and probabilistic sensitivity analyses showed that the results were robust. Conclusion With respect to the WTP threshold of three times per capita GDP in China in 2021, PFO closure is a cost-effective method for Chinese cryptogenic stroke patients with PFO, as shown in the 30-year simulation.

Echocardiographic characteristics of transcatheter closure of patent foramen ovale with mallow biodegradable occluder: A single-center, phase III clinical study. Front Cardiovasc Med 2022; 9:945275. [PMID: 36035958 PMCID: PMC9411996 DOI: 10.3389/fcvm.2022.945275] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Accepted: 07/18/2022] [Indexed: 12/03/2022] Open
Abstract
Background Transcatheter occlusion of patent foramen ovale (PFO) has become a recognized treatment option for high-risk PFO-related diseases. However, traditional metal occluders have some disadvantages, such as permanent retention in the body, abrasion of tissues, and obstruction of access to the left side of the heart for interventional procedures. With biodegradable occluders that release non-toxic degradation products and are absorbable by the body, the risk of long-term complications could be greatly reduced. The experimental results of using a PFO-degradable occluder in beagle dogs in early stages, independently developed by Shanghai Mallow Medical Instrument Co., Ltd., showed that the occluding umbrella disc network was degraded 6 months after occlusion. The occluder also showed good memory, biocompatibility, and mechanical properties. Methods As one of the multi-center research units, this prospective Phase III clinical trial study included 16 patients with PFO-related complications who were treated with a degradable occluder. The follow-up period lasted for 12 months to analyze the echocardiographic characteristics and procedural feasibility. Results The immediate success rate of the procedure was 100% with no serious complications. Postoperative color Doppler transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) at 12 months showed that one patient with atrial septal aneurysm (ASA) had a residual shunt at the edge of the occluder, and contrast transcranial Doppler (cTCD) showed that all patients were grade I or 0 right-to-left shunts (RLS), indicating that the occlusion success rate was 100%. The occluder gradually degraded after the procedure, particularly when the umbrella disc structure became vague, and the size of the occluder decreased significantly 6 months after occlusion. Conclusions PFO closure with a Mallow degradable occluder has a high plugging success rate, is safe and effective, and has no serious complications. However, for PFO closure with special anatomical features, further research with a larger sample size is required. TTE can dynamically, conveniently, and accurately observe the entire degradation process of the occluder. Clinical Trial Registration ChiCTR1900024036.

Percutaneous Patent Foramen Ovale Closure in Patients with Cryptogenic Stroke or Transient Ischemic Attack: A Retrospective Study. BIOMED RESEARCH INTERNATIONAL 2022; 2022:2614225. [PMID: 35178445 PMCID: PMC8844344 DOI: 10.1155/2022/2614225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 12/06/2021] [Indexed: 11/17/2022]
Abstract
Background Patent foramen ovale (PFO) is associated with cryptogenic stroke (CS). Transcatheter closure of PFO is superior to pharmacotherapy for patients with CS or transient ischemic attack (TIA). More evidence is needed to evaluate the efficacy and safety of PFO closure in Chinese patients. Methods This study enrolled ten CS patients and two TIA patients (mean age of 40.8 ± 9.7 y), including seven males (58%) and five females (42%) who underwent PFO closure in our center from January 2017 to July 2019. Baseline data, imaging data, and RoPE (Risk of Paradoxical Embolism) score were collected retrospectively. The preprocedural assessment and percutaneous transcatheter PFO closure were described in detail. The perioperative complications and follow-ups were recorded from all patients. Results Among ten patients with CS, eight patients had a RoPE score of >6 and two patients had a RoPE score of 6. MRI confirmed multiple infarcts in seven cases, and infarct involving the cortex in nine cases. Abnormal ECG was found in three patients and abnormal Echo in four patients. Right-to-left shunt (RLS) was detected in all the patients by cTCD or cTTE. To be specific, RLS was observed in nine of the ten TEE-detected patients. No case had PFO complicated with atrial septal aneurysm (ASA). The success rate of PFO closure was 91.6%. No serious perioperative complications were observed. During a mean time of 26.5 ± 8 months (15-41 months) of follow-up, no recurrent cerebral infarction, TIA, or thromboembolism were detected in postoperative patients. Conclusions PFO closure is safe and effective in the treatment of Chinese patients with CS or TIA.

Abstract
PURPOSE OF REVIEW Device embolization is a rare but potentially life-threatening complication of transcatheter structural heart interventions and may require prompt intervention. The present work aims to provide an overview of strategies for device retrievals in order to better guide the evaluation and management of device embolization. RECENT FINDINGS Although the evolution of transcatheter device therapies has had a tremendous impact on the management in structural heart disease, availability of various retrieval devices, knowledge in how to use them, and multidisciplinary collaboration are key for successful device retrieval. Understanding the reasons for embolization, strategies to avoid embolization, and the techniques for retrieval of devices used in structural heart disease should be appreciated by the treating physician.

Abstract
Objective: This study aimed to develop and validate a nomogram to predict cessation of patent foramen ovale (PFO) patients with migraine headache after percutaneous closure. Methods: A total of 247 eligible patients with PFO and migraine after percutaneous closure between May, 2016 and May, 2018 were divided into a development cohort (n = 149) and a validation cohort (n = 98). The primary end point was cessation of migraine at follow-up of 1 year after the procedure measured by the Migraine Disability Assessment Score (MIDAS). In the development cohort, the LASSO regression was used data dimension reduction. A multivariable logistic regression analysis was used to develop the predicting nomogram. The performance of the nomogram was assessed by concordance index (C-index), calibration and clinical usefulness. The results were validated in the validation cohort. Results: Migraine with aura, history of antiplatelet, and the right-to-left shunt (RLS) at rest were identified as significant predictors based on the analysis of multivariate logistic regression. The nomogram incorporating these variables showed good calibration and discrimination in the development cohort with C-index of 0.906 (95% CI: 0.847–0.965), which was confirmed using the validation cohort with C-index of 0.827 (95% CI: 0.751–0.903). The nomogram showed good agreement between prediction by nomogram and actual observation. Furthermore, the decision curve indicated that the novel nomogram was clinically useful. Conclusion: The novel nomogram showed favorable predictive accuracy for cessation of migraine among patients with PFO after percutaneous closure and might provide constructive guidance in clinical decision making.

Abstract
OBJECTIVES To report long-term safety and efficacy of combined percutaneous LAA and PFO/ASD closure. METHODS A retrospective study of 370 consecutive patients undergoing LAAC procedures using the Watchman (WM) device. Data were compared between 330 cases only with LAAC procedure (Group I) and 25/5 (PFO/ASD) cases with sequential procedures of LAAC and PFO/ASD closure (Group II). RESULTS Compared to Group I, Group II had more males (86.7% vs. 65.8%, p < 0.05) and a higher rate of stroke (33.3% vs. 10.6%, p < 0.01), but there were no statistical differences in the remaining patient characteristics. During the follow-up period, there were no significant differences between the two groups in embolism events (6.1% vs. 0%, p = 0.39), device related thrombus (5.8% vs 3.3%, p = 1.0), major bleeding (9.4% vs. 6.7%, p = 1.0) and cardiac death (3.6% vs. 0%, p = 0.61). The observed rate of all thromboembolic events by Kaplan-Meier analysis was decreased by 39.9% and 100% and the observed annual rate of bleeding was reduced by 32.9% and 57.6% in Group I and Group II, respectively. CONCLUSIONS LAAC combined with PFO/ASD closure might be an ideal choice to prevent stroke and other thrombotic complications in patients with both NVAF and PFO/ASD.

Abstract
Objectives To describe the multidisciplinary assessment of patent foramen ovale (PFO) with substantial right‐to‐left shunting (RLS) and medium‐term follow‐up after PFO closure for stroke or transient ischemic attack (TIA). Background PFO closure is a therapeutic option to prevent recurrent ischemic event in patients with cryptogenic stroke and TIA. The apparent lack of benefit seen in previous studies was in part due to the inclusion of patients with alternate mechanisms of stroke/TIA. However, the long‐term follow‐up results of RESPECT trial confirmed that PFO closure could reduce the recurrence rate of stroke compared to medical therapy. The obvious difference between RESPECT and the other studies is that RESPECT recruited more relevant patients with substantial RLS. Methods From May 2013 to October 2015, all subjects diagnosed as cryptogenic stroke or TIA with substantial RLS who underwent PFO closure at our institution were included. All patients underwent multidisciplinary assessment to exclude stroke/TIA with definite etiology. Baseline characteristics, clinical manifestations, procedural, and follow‐up data were reviewed. Results A total of 219 consecutive patients with substantial RLS undergoing PFO closure were identified. There were no procedure‐related deaths, strokes, or TIA. Mean follow‐up was 2.0 ± 0.7 years. Early residual shunting was visible in 9 patients (4.1%); however, during follow‐up, only 3 patients (1.4%) had residual RLS detected by contrast transthoracic echocardiography (cTTE). The annual risk of recurrent ischemic stroke or TIA was 0.457%. Conclusions PFO closure can be performed safely and effectively in patients with cryptogenic stroke or TIA. In selected patients with substantial RLS, following appropriate multidisciplinary assessment, excellent results with low incidence of recurrent events may be achieved.
