[PMID: 39323850 PMCID: PMC11421997 DOI: 10.1016/j.heliyon.2024.e37730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 08/30/2024] [Accepted: 09/09/2024] [Indexed: 09/27/2024] Open
Abstract
Background Stroke, which is mainly caused by thrombus formation in the left atrial appendage, represents the most prevalent complication of atrial fibrillation (AF). Both percutaneous left atrial appendage occlusion (p-LAAO) and surgical LAAO (s-LAAO) are used to treat AF and prevent stroke events. However, no head-to-head randomized controlled trials (RCTs) compared these strategies. Objective To examine the efficacy and safety of diverse strategies for reducing stroke risk using a network meta-analysis (NMA). Methods PubMed, EMBASE, and Cochrane repositories were explored to identify RCTs involving p-LAAO or s-LAAO, and five were included for NMA. This investigation adhered to the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-analyses. The NMA was pooled using the Bayesian random effect framework. All findings were expressed as odds ratios accompanied by a 95 % confidence interval.The primary efficacy endpoint was any stroke (AS), and the secondary efficacy endpoint was combined AS and systematic embolism (AS/SE). The primary and secondary safety endpoints were major bleeding (MB) and all-cause death (ACD), respectively. Results Our meta-analysis incorporated 6337 individuals diagnosed with AF. The NMA demonstrated a reducing trend in AS and AS/SE for s-LAAO versus p-LAAO, while p-LAAO showed a benefit in reducing MB and ACD. Conclusions and Relevance: s-LAAO could potentially benefit individuals at elevated risk for stroke, whereas p-LAAO may be linked to a reduced likelihood of bleeding.

Single-Operator Left atrial appendage Occlusion utilizing Conscious sedation TEE, Lack of Outpatient pre-imaging, and Same-day Expedited discharge (SOLO-CLOSE): A comparison with conventional approach. Catheter Cardiovasc Interv 2024; 104:330-342.

Abstract
BACKGROUND Left atrial appendage occlusion (LAAO) with WATCHMAN currently requires preprocedural imaging, general anesthesia, and inpatient overnight admission. We sought to facilitate simplification of LAAO. AIMS We describe and compare SOLO-CLOSE (single-operator LAA occlusion utilizing conscious sedation TEE, lack of outpatient pre-imaging, and same-day expedited discharge) with the conventional approach (CA). METHODS A single-center retrospective analysis of 163 patients undergoing LAAO between January 2017 and April 2022 was conducted. The SOLO-CLOSE protocol was enacted on December 1, 2020. Before this date, we utilized the CA. The primary efficacy endpoint was defined as successful LAAO with ≤5 mm peri-device leak at time of closure. The primary safety endpoint was the composite incidence of all-cause deaths, any cerebrovascular accident (CVA), device embolization, pericardial effusion, or major postprocedure bleeding within 7 days of the index procedure. Procedure times, 7-day readmission rates, and cost analytics were collected as well. RESULTS Baseline characteristics were similar in both cohorts. Congestive heart failure (37.5% vs. 11.1%) and malignancy (28.8% vs. 12.5%) were higher in SOLO-CLOSE. Median CHA2D2SVASc score was 5 in both cohorts. The primary efficacy endpoint was met 100% in both cohorts. Primary safety endpoint was similar between cohorts (p = 0.078). Mean procedure time was 30 min shorter in SOLO-CLOSE (p < 0.01). Seven-day readmissions for SOLO-CLOSE was zero. After SOLO-CLOSE implementation, there was a 188% increase in positive contribution margin per case. CONCLUSIONS The SOLO-CLOSE methodology offers similar efficacy and safety when compared to the CA, while improving clinical efficiency, reducing procedural times, and increasing economic benefit.

Front Cardiovasc Med 2024; 11:1389811. [PMID: 38841258 PMCID: PMC11150762 DOI: 10.3389/fcvm.2024.1389811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Accepted: 04/29/2024] [Indexed: 06/07/2024] Open
Abstract
Objective The effect of atrial fibrillation (AF) patterns on outcomes remains controversial. This study aims to evaluate the influence of AF type on the risk of cardiocerebrovascular events after left atrial appendage closure (LAAC) at long-term follow-up. Methods AF was categorized as paroxysmal AF (PAF) and non-PAF (NPAF). The baseline characteristics, procedural data, peri-procedural complications, and long-term outcomes between patients with PAF and NPAF after LAAC were compared. Results We analyzed 410 AF patients (mean age 74.8 ± 8.2 years; 271 male; 144 with PAF, 266 NPAF). The NPAF group tended to be older (≥75 years), male, and have chronic kidney disease (CKD) compared with the PAF group. The procedural data and peri-procedural complications were comparable. During 2.2 ± 1.5 years of follow-up, the incidences of thromboembolism, major bleeding, and device-related thrombus (DRT) did not differ between the two groups. The observed risk of thromboembolism and major bleeding was significantly lower than the estimated risk based on the CHA2DS2-VASc and HAS-BLED scores, respectively, in patients who underwent LAAC, regardless of the AF type. NPAF patients were associated with a higher risk of all-cause mortality, non-cardiovascular mortality, and combined efficacy endpoints. This association disappeared after propensity score matching (PSM) analysis. Conclusions The risk of thromboembolism and major bleeding was lower in patients who underwent LAAC, regardless of the AF type. Although NPAF often coexists with multiple risk factors, it was not associated with worse long-term outcomes after LAAC when compared with PAF.

BMC Cardiovasc Disord 2024; 24:175. [PMID: 38515032 PMCID: PMC10956221 DOI: 10.1186/s12872-024-03843-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 03/13/2024] [Indexed: 03/23/2024] Open
Abstract
BACKGROUND Approximately 90% of intracardial thrombi originate from the left atrial appendage in non-valvular atrial fibrillation patients. Even with anticoagulant therapy, left atrial appendage thrombus (LAAT) still occurs in 8% of patients. While left atrial appendage closure (LAAC) could be a promising alternative, the current consensus considers LAAT a contraindication to LAAC. However, the feasibility and safety of LAAC in patients with LAAT have yet to be determined. METHODS This systematic review synthesizes published data to explore the feasibility and safety of LAAC for patients with LAAT. RESULTS This study included a total of 136 patients with LAATs who underwent successful LAAC. The Amulet Amplatzer device was the most frequently utilized device (48.5%). Among these patients, 77 (56.6%) had absolute contraindications to anticoagulation therapy. Cerebral protection devices were utilized by 47 patients (34.6%). Transesophageal echocardiography (TEE) is the primary imaging technique used during the procedure. Warfarin and novel oral anticoagulants were the main anticoagulant medications used prior to the procedure, while dual antiplatelet therapy was primarily used post-procedure. During a mean follow-up period of 13.2 ± 11.5 months, there was 1 case of fatality, 1 case of stroke, 3 major bleeding events, 3 instances of device-related thrombus, and 8 cases of peri-device leakage. CONCLUSIONS This review highlights the preliminary effectiveness and safety of the LAAC procedure in patients with persistent LAAT. Future large-scale RCTs with varied LAAT characteristics and LAAC device types are essential for evidence-based decision-making in clinical practice.

Abstract
BACKGROUND We sought to evaluate respiratory complications in heart failure patients undergoing left atrial appendage occlusion (LAAO) for stroke prevention in atrial fibrillation. METHODS Adult admissions (>18 years) undergoing LAAO during 2016-2020 were identified from the National Inpatient Sample. Heart failure (HF) was stratified into systolic (SHF) and diastolic heart failure (DHF) and were compared to those without HF. Outcomes of interested included acute respiratory failure, use of non-invasive and invasive mechanical ventilation, and in-hospital mortality. RESULTS Of 74,440 admissions for atrial fibrillation undergoing LAAO, SHF and DHF were noted in 8335 (11.2%) and 10,925 (14.7%), respectively. The SHF cohort was predominantly male (78%) whereas DHF cohort were female (53%). Compared to those without HF, presence of SHF (2.3% vs. 0.6%; adjusted odds ratio [OR] 1.61 [95% confidence interval {CI} 1.10-2.36]; p = 0.01) and DHF (2.8% vs. 0.6%; adjusted OR 2.20 [95% CI 1.58-3.06]; p < 0.001) were associated with higher rates of acute respiratory failure. SHF (1.7% vs. 0.6%; adjusted OR 1.70 [95% CI 1.07-2.71]; p = 0.02) group but not DHF (1.2% vs. 0.6%; adjusted OR 1.21 [95% CI 0.78-1.89]; p = 0.39) was associated with higher rates of non-invasive ventilation, whereas the DHF group (0.9% vs. 0.2%; adjusted OR 1.91 [95% CI 1.08-3.34]; p = 0.02) but not SHF (0.8% vs. 0.2%; adjusted OR 1.54 [95% CI 0.83-2.84]; p = 0.17) was associated with higher rates of invasive mechanical ventilation use. In-hospital mortality was comparable between cohorts. CONCLUSION Compared to those without HF, atrial fibrillation admissions with HF undergoing LAAO had higher rates of acute respiratory failure and mechanical ventilation rates without differences in in-hospital mortality.

Abstract
BACKGROUND Transesophageal echocardiography (TEE) is the gold standard test for the diagnosis of left atrial appendage (LAA) thrombus. Nonetheless, computerized tomography angiography (CTA) is readily used to exclude LAA thrombus before pulmonary vein isolation (PVI) and LAA closure procedures. We aimed to assess the comparability of LAA thrombus diagnosis using chest CTA scans in patients with atrial fibrillation who underwent TEE. METHODS Retrospective collection of consecutive patients with atrial fibrillation who underwent TEE and chest CTA within 30 days and had evidence of spontaneous echo contrast (SEC) or LAA thrombus on TEE. Clinical, demographic, and echo data were collected. Prospective analysis of the CTA for evidence of LAA thrombus in the same group of patients was performed. We compared the findings of the two modalities. RESULTS Out of 1550 patients with atrial fibrillation who underwent TEE examinations in the study period, 63 patients underwent TEE within 30 days of a chest CTA scan. Twenty-three patients had LAA thrombus and 40 had some degree of SEC according to TEE. On CTA, 11 were interpreted as positive with a high level of suspicion for the presence of an LAA thrombus. Six patients (26.1%) had LAA thrombus according to both CT and TEE. Therefore, low concordance was found between test results (chi-squared continuity correction = 5.5, df = 1, and P -value = 0.01902). CONCLUSION The discrepancy between CTA and TEE results suggests these examinations might be more suitable as complementary examinations to exclude LAA thrombus.

Abstract
BACKGROUND Left atrial appendage occlusion (LAAO) may be a viable option for stroke prevention in patients with non-valvular atrial fibrillation and a contraindication for oral anticoagulation. No evidence evaluating the safety of this procedure in patients with a cardiac implantable electronic device (CIED) exists. The aim of this study was to evaluate whether CIED function is affected by LAAO and to explore LAAO procedural characteristics and complications in patients with a CIED. METHODS This single-center cohort study included consecutive patients scheduled for percutaneous LAAO. Patients with a CIED prior to LAAO were selected and compared to the patients without CIED, concerning procedural characteristics and peri-procedural complications. In the group of patients with CIEDs, essential pacemaker integrity parameters were compared before and after the procedure to detect possible micro and macro lead displacements. RESULTS Thirty-one patients with CIED were scheduled for LAAO (age 73.7 ± 5.4 years, 65% males, CHA2DS2-VASc 4.3 ± 1.5, and HAS-BLED 3.3 ± 1.0). The 245 patients without CIED were younger, and HAS-BLED-score was slightly lower (69.4 ± 8.2 years, p < 0.001; 2.8 ± 1.0, p = 0.022). Patients without CIED more frequently underwent LAAO combined with catheter ablation (p = 0.002). All other procedural characteristics were comparable between both groups. No visible lead displacement was observed on chest X-ray after LAAO. Additionally, no differences in impedance, threshold, or intracardiac sensing in various CIED lead locations were found prior versus post LAAO. CONCLUSION This study supports the feasibility and safety of LAAO in patients with a CIED.

Cureus 2023; 15:e47444. [PMID: 38021921 PMCID: PMC10659817 DOI: 10.7759/cureus.47444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 10/21/2023] [Indexed: 12/01/2023] Open
Abstract
Background The WATCHMAN™ device is a Food and Drug Administration (FDA)-approved device that reduces the risk of stroke from atrial fibrillation (AF) in those who have a contraindication to taking oral anticoagulation. A key aspect of this device implantation is the choice of medical therapy in the months after device implantation with Vitamin K antagonist oral anticoagulants (OAC) being the mainstay of therapy but dual antiplatelet therapy (DAPT) poses as a potential alternative to patients who have a contraindication to OAC use. Methods Our single-center study retroactively followed 150 patients post-WATCHMAN™ implantation and evaluated outcomes at 12 months post-implantation in two cohorts, those treated with OAC or DAPT. Our results were obtained via chart review of a single-center electronic medical records system. Results In our study, 67.33% of study patients were males and 49.33% were on OAC compared to 36.00% that were on DAPT. Ten patients were not able to undergo device implantation. With this analysis, we found similarly low rates of complications such as stroke and device-associated thrombosis (DAT) in both groups. Our DAPT cohort did have a higher number of gastrointestinal (GI) bleeding but this was not significant in our analysis. Discussion Our study compares to larger trials that show similar outcomes between OAC and DAPT post-implantation of the WATCHMAN™ device. The increased number of GI bleeding in our DAPT cohort could be the result of the underlying advanced age and comorbidity of that patient cohort. Conclusion Our results suggest that DAPT is a safe alternative to OAC for patients undergoing WATCHMAN™ implantation.

Atrial fibrillation is a major risk factor for stroke. Left atrial appendage closure (LAAC) has emerged as an alternative to anticoagulation for patients with high risk of bleeding. Diabetes mellitus (DM) is associated with adverse events after cardiac procedures. We sought to compare procedural and hospital outcomes in patients who underwent LAAC with and without DM. The Nationwide Inpatient Database was queried for patients with atrial fibrillation who underwent LAAC between January 1, 2016, and December 31, 2019. The primary outcome was all adverse events that included in-hospital death, acute myocardial infarction, cardiac arrest, stroke, pericardial effusion, pericardial tamponade, pericardiocentesis, pericardial window, and postprocedural hemorrhage requiring blood transfusion. Analysis included 62,220 patients who underwent LAAC from 2016 to 2019; 34.9% of patients had DM. There was a slight increase in the percentage of patients who underwent LAAC who had DM during the study period, from 29.92% to 34.93%. In unadjusted and adjusted analysis, there was no significant difference in all adverse events between patients with and without DM who underwent LAAC (9.18% vs 8.77%, respectively, adjusted p = 0.63), and no difference in length of stay. Patients with DM have higher risk of acute kidney injury (3.75 vs 1.96%, p <0.001). This nationwide retrospective study demonstrates that DM is not associated with an increase in adverse event rates in patients who underwent LAAC.

Abstract
Atrial fibrillation (AF) is the most common cardiac arrhythmia in adults. The left atrial appendage (LAA) is the most likely source of thrombus formation in patients with non-valvular atrial fibrillation (NVAF). Left atrial appendage closure (LAAC) represents an effective alternative to NOAC in patients with NVAF. Expert consensus documents recommend intraprocedural imaging by means of either transesophageal echocardiography (TEE) or intracardiac echocardiography (ICE) in addition to standard fluoroscopy to guide LAAC. TEE-guided LAAC usually requires general anesthesia. The ICE technique is a "minimalist approach", without general anesthesia, but ICE imaging techniques are not yet simplified and standardize, and the ICE may result in inferior image quality compared with that of TEE. Another "minimalist approach" can be the use of ICE via the esophageal route (ICE-TEE), that jet is validated to identify the presence of LAA thrombi in patients and to perform other procedures. In our cath laboratory ICE-TEE to guide LAAC is used in some complex patients. Indeed, our single center experience suggests that ICE-TEE could be a good alternative imaging technique to guide LAAC procedure without general anesthesia.

Abstract
Cardiac medical devices (CMDs) are required when the patient's cardiac capacity or activity is compromised. To guarantee its correct functionality, the building materials in the development of CMDs must focus on several fundamental properties such as strength, stiffness, rigidity, corrosion resistance, etc. The challenge is more significant because CMDs are generally built with at least one metallic and one polymeric part. However, not only the properties of the materials need to be taken into consideration. The biocompatibility of the materials represents one of the major causes of the success of CMDs in the short and long term. Otherwise, the material will lead to several problems of hemocompatibility (e.g., protein adsorption, platelet aggregation, thrombus formation, bacterial infection, and finally, the rejection of the CMDs). To enhance the hemocompatibility of selected materials, surface modification represents a suitable solution. The surface modification involves the attachment of chemical compounds or bioactive compounds to the surface of the material. These coatings interact with the blood and avoid hemocompatibility and infection issues. This work reviews two main topics: 1) the materials employed in developing CMDs and their key characteristics, and 2) the surface modifications reported in the literature, clinical trials, and those that have reached the market. With the aim of providing to the research community, considerations regarding the choice of materials for CMDs, together with the advantages and disadvantages of the surface modifications and the limitations of the studies performed.

Abstract
Viscoelastic testing (VET), such as thromboelastography, can measure whole blood coagulation dynamics in real time and is used across a range of clinical settings, including cardiac surgery, liver transplant, and trauma. The use of modified thromboelastography with platelet function assessment (TEG(R) PlateletMapping(R) Assay) can provide an analysis of platelet contribution to hemostasis, including the contribution of the P2Y12 receptor and thromboxane pathway to platelet function. The TEG PlateletMapping Assay has shown high correlation with the current gold standard test of platelet function, light transmission aggregometry, to measure arachidonic acid and adenosine diphosphate agonist-induced platelet activation. Studies have also shown comparable results with other whole blood platelet function tests. In this review, we explore the clinical applications of modified thromboelastography with platelet function assessment. This includes guiding dual antiplatelet therapy in relation to cardiac procedures, such as percutaneous coronary interventions, transcatheter aortic valve replacement, and left atrial appendage closure. We also explore the developing use of thromboelastography in the emergency care setting of coronavirus disease 2019, which is commonly associated with a hypercoagulable and hypofibrinolytic state. Despite a general lack of high-quality, grade 1 evidence regarding the use of modified thromboelastography with platelet function assessment in these disease areas, the ability of the TEG PlateletMapping Assay to measure global hemostasis and platelet reactivity rapidly and to view and evaluate results at the point of care makes it a promising area for further study for managing patient treatment and optimizing hemostatic therapy.

Abstract
Atrial fibrillation (AF) is one of the most common cardiac arrhythmias encountered. Aggressive and appropriate management, along with identification and modification of risk factors, remains at the forefront of evidence-based practice. Thrombus formation (primarily in the left atrial appendage) and consequent thromboembolism are risks associated with AF. Anticoagulation is utilized to prevent and reduce AF-induced complications such as stroke, heart failure, and death. However, in instances when the risk of bleeding from anticoagulation outweighs the benefits of stroke prevention, other modalities such as left atrial appendage closure (LAAC) devices like the WATCHMAN device (Boston Scientific, MA) are utilized. LAAC devices, such as the WATCHMAN device, are also not without significant risks, one of them being device-related thrombus (DRT) formation. We present a case of device-related thrombus formation post WATCHMAN implantation and a subsequent embolic cerebrovascular accident (CVA).

Abstract
ABSTRACT Transient ischemic attack (TIA) is defined as a transient episode of neurological dysfunction resulting from focal brain, spinal cord, or retinal ischemia, without associated infarction. Consequently, a TIA encompasses amaurosis fugax (AF) that is a term used to denote momentary visual loss from transient retinal ischemia. In this review, we use the word TIA to refer to both cerebral TIAs (occurring in the brain) and AF (occurring in the retina). We summarize the key components of a comprehensive evaluation and management of patients presenting with cerebral and retinal TIA.All TIAs should be treated as medical emergencies, as they may herald permanent disabling visual loss and devastating hemispheric or vertebrobasilar ischemic stroke. Patients with suspected TIA should be expeditiously evaluated in the same manner as those with an acute stroke. This should include a detailed history and examination followed by specific diagnostic studies. Imaging of the brain and extracranial and intracranial blood vessels forms the cornerstone of diagnostic workup of TIA. Cardiac investigations and serum studies to evaluate for etiological risk factors are also recommended.The management of all TIAs, whether cerebral or retinal, is similar and should focus on stroke prevention strategies, which we have categorized into general and specific measures. General measures include the initiation of appropriate antiplatelet therapy, encouraging a healthy lifestyle, and managing traditional risk factors, such as hypertension, dyslipidemia, and diabetes. Specific management measures require the identification of a specific TIA etiology, such as moderate-severe (greater than 50% of stenosis) symptomatic extracranial large vessel or intracranial steno-occlusive atherosclerotic disease, aortic arch atherosclerosis, and atrial fibrillation.

Abstract
BACKGROUND Thromboembolism-associated stroke is the most feared complication of Atrial fibrillation (AF). Percutaneous left atrial appendage closure (pLAAC) is indicated for stroke prevention in patients with AF who can't tolerate long-term anticoagulation. We aim to study gender differences in peri-procedural and readmissions outcomes in pLAAC patients. METHODS Using the national readmission database from January 2016 to December 2018, AF patients undergoing the pLAAC procedure were identified. We used multivariate logistic regression analyses and time-to-event Cox regression analyses to conduct the study. Propensity matching with the Greedy method was done for the accuracy of results. RESULT 28,819 patients were included in our study. Among them 11,946 (41.5%) were women and 16,873 (58.6%) were men. The mean age of overall population was 76.1 ± 8.5 years, with women ~ 1 year older than men. The overall rate of complications was higher in women (8.6% vs 6.6%, P<0.001), primarily driven by bleeding-related complications i.e., Major bleed (OR: 1.32 95% CI: 1.03-1.69, p=0.029), blood transfusion (OR: 1.45, 95% CI: 1.06-1.97, p=0.019) and cardiac tamponade (OR: 1.80, 95% CI: 1.13-2.89, p=0.014). Women had two times higher peri-procedural ischemic stroke. There was no difference in peri-procedural mortality. Women remained at 20% and 13% higher risk for readmission at 30 days and 6 months of discharge. CONCLUSION Women had higher peri-procedural complications and were at higher risk of readmissions at 30 days and six months. However, there was no difference in mortality during the index hospitalization. Further studies are necessary to determine causality. This article is protected by copyright. All rights reserved.
