Abstract
The left atrial appendage (LAA) has gained increasing attention in the field of cardiology as a potential site for intervention in patients with atrial fibrillation (AF) and an elevated risk of thromboembolic events. Left atrial appendage occlusion (LAAO) has emerged as a promising therapeutic strategy to mitigate the risk of stroke and systemic embolism, especially in individuals who are unsuitable candidates for long-term anticoagulation therapy. This review aims to provide a comprehensive analysis of the current state of LAAO, encompassing its anatomic considerations, procedural techniques, clinical outcomes, and future directions.

Abstract
Atrial fibrillation (AF) is associated with an increased risk of stroke and systemic embolism, and the left atrial appendage (LAA) has been identified as a principal source of thromboembolism in these patients. While oral anticoagulation is the current standard of care, LAA closure (LAAC) emerges as an alternative or complementary treatment approach to reduce the risk of stroke or systemic embolism in patients with AF. Moderate-sized randomized clinical studies have provided data for the efficacy and safety of catheter-based LAAC, largely compared with vitamin K antagonists. LAA device iterations, advances in pre- and peri-procedural imaging, and implantation techniques continue to increase the efficacy and safety of LAAC. More data about efficacy and safety of LAAC have been collected, and several randomized clinical trials are currently underway to compare LAAC with best medical care (including non-vitamin K antagonist oral anticoagulants) in different clinical settings. Surgical LAAC in patients with AF undergoing cardiac surgery reduced the risk of stroke on background of anticoagulation therapy in the LAAOS III study. In this review, we describe the rapidly evolving field of LAAC and discuss recent clinical data, ongoing studies, open questions, and current limitations of LAAC.

Anesthetic Choice for Percutaneous Transcatheter Closure of the Left Atrial Appendage: A National Anesthesia Clinical Outcomes Registry Analysis. Ann Card Anaesth 2024; 27:220-227. [PMID: 38963356 DOI: 10.4103/aca.aca_14_24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Accepted: 03/09/2024] [Indexed: 07/05/2024] Open
Abstract
CONTEXT Left atrial appendage closure (LAAC) was developed as a novel stroke prevention alternative for patients with atrial fibrillation, particularly for those not suitable for long-term oral anticoagulant therapy. Traditionally, general anesthesia (GA) has been more commonly used primarily due to the necessity of transesophageal echocardiography. AIMS Compare trends of monitored anesthesia care (MAC) versus GA for percutaneous transcatheter LAAC with endocardial implant and assess for independent variables associated with primary anesthetic choice. SETTINGS AND DESIGN Multi-institutional data collected from across the United States using the National Anesthesia Clinical Outcomes Registry. MATERIAL AND METHODS Retrospective data analysis from 2017-2021. STATISTICAL ANALYSIS USED Independent-sample t tests or Mann-Whitney U tests were used for continuous variables and Chi-square tests or Fisher's exact test for categorical variables. Multivariate logistic regression was used to assess patient and hospital characteristics. RESULTS A total of 19,395 patients underwent the procedure, and 352 patients (1.8%) received MAC. MAC usage trended upward from 2017-2021 (P < 0.0001). MAC patients were more likely to have an American Society of Anesthesiologists (ASA) physical status of≥ 4 (33.6% vs 22.89%) and to have been treated at centers in the South (67.7% vs 44.2%), in rural locations (71% vs 39.5%), and with lower median annual percutaneous transcatheter LAAC volume (102 vs 153 procedures) (all P < 0.0001). In multivariate analysis, patients treated in the West had 85% lower odds of receiving MAC compared to those in the Northeast (AOR: 0.15; 95% CI 0.03-0.80, P = 0.0261). CONCLUSIONS While GA is the most common anesthetic technique for percutaneous transcatheter closure of the left atrial appendage, a small, statistically significant increase in MAC occurred from 2017-2021. Anesthetic management for LAAC varies with geographic location.

Abstract
3-dimensional (3D) intracardiac echocardiography (ICE) is emerging as a promising complement and potential alternative to transesophageal echocardiography for imaging guidance in structural heart interventions. To establish standardized practices, our multidisciplinary expert position statement serves as a comprehensive guide for the appropriate indications and utilization of 3D-ICE in various structural heart procedures. The paper covers essential aspects such as the fundamentals of 3D-ICE imaging, basic views, and workflow recommendations specifically tailored for ICE-guided structural heart procedures, such as transeptal puncture, device closure of intracardiac structures, and transcatheter mitral and tricuspid valve interventions. Current challenges, future directions, and training requirements to ensure operator proficiency are also discussed, thereby promoting the safety and efficacy of this innovative imaging modality to support expanding its future clinical applications.

Abstract
BACKGROUND Data regarding left atrial appendage closure (LAAC) in patients with left atrial appendage (LAA) thrombus are limited. Recently published cases have mostly been guided by transesophageal echocardiography. Intracardiac echocardiography (ICE) is now widely used during LAAC procedures. OBJECTIVE This is the first study to report the feasibility of LAAC in patients with LAA thrombus guided by ICE. METHODS Patients with persistent LAA thrombus despite anticoagulation or contraindications to anticoagulation who underwent a modified ICE-guided LAAC procedure between June 2021 and April 2023 were included. Periprocedural events and clinical outcomes during follow-up were recorded. RESULTS A total of 12 patients (mean age 65 ± 7 years; 92% male) were included: 10 with persistent LAA thrombus and 2 with contraindications to anticoagulation. Most of the thrombus was at the apex (n = 6), followed by the body (n = 3) and the ostium (n = 3). A LAmbre device was used and successfully implanted in all patients with the guidance of ICE. No thrombotic material was retrieved from patients with the protection of cerebral protection device (n = 11). No patient experienced severe periprocedural complications. All patients completed transesophageal echocardiography follow-up, and no device-related thrombus or peridevice leak > 3 mm was detected. None of the patients experienced stroke/transient ischemic attack, systemic embolism, or major bleeding events during a median follow-up of 147 days (interquartile range 80-306 days). CONCLUSION LAAC using the LAmbre device guided by ICE may be feasible in patients with LAA thrombus when performed by experienced operators.

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. [PMID: 38736248 DOI: 10.1002/ccd.31073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 04/24/2024] [Accepted: 04/29/2024] [Indexed: 05/14/2024]
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.

Safety and Efficacy of Mini-Invasive Left Atrial Appendage Closure: A Propensity-Score Analysis. Can J Cardiol 2024:S0828-282X(24)00289-7.

Abstract
BACKGROUND Left atrial appendage closure (LAAC) for prevention of stroke is validated in patients with nonvalvular atrial fibrillation (NVAF) contraindicated to oral anticoagulation. General anaesthesia (GA) is often used for procedural guidance by transesophageal echocardiography (TEE); however, its use may be challenging in some patients. The aim of the study was to evaluate the safety and the midterm efficacy of a mini-invasive LAAC strategy using micro-TEE under procedural sedation. METHODS Comparison by propensity score of 2 cohorts of consecutive patients who underwent LAAC: standard TEE-guided LAAC (3-dimensional [3D] TEE under GA) and mini-invasive LAAC strategy (micro-TEE under procedural sedation). The primary endpoint was a composite of embolic or bleeding events, significant per procedural complication, and cardiovascular deaths within 3 months after LAAC. RESULTS In total, 432 patients were included (78.7 ± 8 years old, 32.4% of women, CHA2DS2VASC score: 4.9 ± 1.1); 127 patients underwent mini-invasive LAAC strategy and were compared with 305 patients standard TEE-guided LAAC. The mini-invasive strategy was achieved in 122 of 127 (96.1%) planned patients. The primary endpoint occurred in 11.2% of patients from the mini-invasive LAAC strategy group and in 10.3% of patients from the standard TEE group (absolute difference = 0.9% [-6.4; 4.5], hazard ratio = 1.11 [0.56; 2.19], P = 0.76). Procedural times, fluoroscopy duration, and hospital stays were shorter in the mini-invasive LAAC strategy group (P < 0.001). CONCLUSIONS The mini-invasive LAAC strategy is safe and effective compared with the standard TEE-guided LAAC strategy. A mini-invasive LAAC strategy may also be an important tool to help physicians to treat more patients as LAAC indications evolve in the future.

Abstract
Background Device-related thrombosis (DRT) is a known complication to left atrial appendage closure (LAAC). The surface of a LAAC device should ideally have antithrombotic properties. The novel WATCHMAN FLX Pro (WFP) incorporates a fluoropolymer-coated fabric membrane designed to increase thromboresistance and facilitate endothelialization. Such features could potentially allow for a minimal post-procedural antithrombotic regimen. Radiopaque platinum markers at the device shoulders and a large 40 mm device are other novel features of the WFP. Case summary A 75-year-old man with atrial fibrillation was referred for LAAC due to prior subdural haemorrhage during direct-acting anticoagulation treatment. He underwent the first-in-human WFP implantation as part of the WATCHMAN FLX Pro CT study (NCT05567172). Computed tomography (CT) was used for pre-planning, and the procedure was performed under local analgesia guided by intracardiac echocardiography from the left atrium (LA) without any complications. Post-procedural antithrombotic treatment consisted of acetylsalicylic acid 75 mg/day only, and 45-day CT, transoesophageal echocardiography (TEE), and magnetic resonance imaging demonstrated optimal device position with complete LAAC. Hypoattenuated thickening (6 mm) appeared on the device as a smooth surface in continuity with the left atrial wall on CT and TEE. A specific magnetic resonance T1-weighted scan, used for visualization of fresh thrombus, suggested this to represent tissue ingrowth rather than thrombus. Discussion The advanced follow-up imaging protocol suggested a good WFP implantation result with signs of tissue ingrowth at 45 days. The added radiopaque markers facilitated optimal deployment, evaluation of device stability during tug test, and assessment of device protrusion into the LA.

Abstract
Contrast media are generally necessary for transcatheter left atrial appendage closure (LAAC), however, it should be avoided in patients with chronic kidney disease (CKD). The objective of this study was to evaluate the safety and feasibility of contrast-free LAAC with WATCHMAN FLX device for patients with CKD. Among 141 patients undergoing LAAC using the WATCHMAN FLX between May 2021 and March 2023, we performed LAAC without contrast media in 10 patients. Procedural and follow-up results were evaluated. The device size was selected based on the transesophageal echocardiographic (TEE) measurements. The device shape was assessed by fluoroscopy, and the device position was adjusted by TEE images. The mean age was 78 ± 4.9 years, CHADS2 score was 3.2 ± 1.1, and the estimated glomerular filtration rate (eGFR) was 28 ± 12 mL/min/1.73m2. The procedure was completed without contrast media in ten patients. Partial recapture of the device was required in four patients, but the initially selected device was finally implanted in all patients. Mean procedure time was significantly shorter in the contrast-free LAAC than in the contrast-use LAAC (41.6 ± 14.1 min vs 30.3 ± 7.6 min, p = 0.01). Postprocedural eGFR did not change from baseline, and there were no adverse events during the hospital stay. Follow-up TEE or cardiac computed tomography performed within 3 months after the procedure revealed no device-related thrombus or peri-device leak > 3 mm, and oral antithrombotic therapy was discontinued in all patients. Our experience shows that contrast-free LAAC using the WATCHMAN FLX device was safe and feasible. Non-contrast LAAC is one of the therapeutic options for patients with severe CKD.

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
Left atrial appendage occlusion (LAAO) is an increasingly used alternative to oral anticoagulation in patients with atrial fibrillation, especially in patients with absolute/relative contraindications to these therapies. This review will cover three main aspects of the procedure. In the fist part of the manuscript, we focus on patient selection. We describe three main categories of patients with primary indication to LAAO, namely patients with previous or at a high risk of intracerebral bleeding, patients with a history of major gastrointestinal bleeding and patients with end-stage renal disease and absolute contraindication to novel oral anticoagulants. Some other potential indications are also described. In the second part of the manuscript, we review available devices, trying to highlight different aspects and potential specific advantages. The last section overviews different ways for pre-, intra- and postprocedural imaging, in order to improve procedural safety and efficacy and ameliorate patient outcome. The characteristics of available contemporary devices and the role of imaging in procedural planning, intraprocedural guidance and follow-up are described.

Abstract
Over the past decade, engineering advances in intracardiac echocardiography (ICE) have improved the ability of an imager or interventionalist to guide not only interatrial septal procedures but now commonly left atrial appendage, tricuspid, and mitral procedures. When transesophageal echocardiography (TEE) is not possible because of anatomic limitations, ICE has proved a useful tool to safely complete structural interventions. ICE will play a growing, key role in structural interventions where anatomic factors strongly favor an intracardiac perspective or augment TEE when imaging is suboptimal.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a risk factor for embolic stroke, and many nonvalvular atrial fibrillation (NVAF) patients have concomitant CKD. Anticoagulation therapy can be challenging in CKD due to increased bleeding risk, and left atrial appendage occlusion (LAAO) may be a promising alternative. OBJECTIVE This systematic review aimed to consolidate current evidence on the safety and effectiveness of transcatheter LAAO in patients with CKD and end-stage renal disease (ESRD). METHODS Medline, Cochrane, and Embase databases were searched from inception to September 2, 2022. We conducted a meta-analysis if an outcome was evaluated in at least two similar studies. RESULTS We included 15 studies with 77,780 total patients. Of the 15 studies, 11 had a cohort design (five prospective and six retrospective), and four were case series. Patients with CKD were older and had a higher prevalence of comorbidities than non-CKD patients. The two groups did not differ in procedural failure rate, vascular complications, or pericardial tamponade. CKD patients exhibited higher odds of in-hospital acute kidney injury (AKI) and bleeding, longer-term bleeding, and mortality than those without CKD. The risk of in-hospital and longer-term cardioembolic events was similar between CKD and non-CKD populations (odds ratio = 1.01 [95% CI 0.70-1.15] and 1.05 [95% CI 0.55-2.00], respectively). Patients with ESRD had higher odds of in-hospital mortality and cardioembolic events than non-ESRD patients, with no differences in risk of pericardial tamponade. CONCLUSIONS Based on observational studies, LAAO may be an effective option to prevent cardioembolic events in CKD. However, CKD patients may have higher odds of AKI and in-hospital and long-term bleeding and mortality. The adverse clinical outcomes observed in CKD patients may be attributed to this population's high burden of comorbidities, especially among those with ERSD, rather than the LAAO procedure itself. To ensure maximum clinical benefit, careful patient selection, management, and surveillance involving multidisciplinary teams are essential for CKD patients undergoing LAAO. Transcatheter Left Atrial Appendage Occlusion (laao) Can Prevent Cardioembolic Events In Chronic Kidney Disease (ckd) Patients. However, Ckd Patients, Particularly Those With End-stage Renal Disease/dialysis (esrd), May Face Increased Odds Of Acute Kidney Injury, In-hospital And Long-term Bleeding, And Mortality. Notably, These Adverse Outcomes In Ckd Patients May Be Linked To Their High Comorbidity Burden, Particularly In Those With Esrd, Rather Than The Laao Procedure Itself.

Abstract
Anticoagulation therapy plays a crucial role in the management of atrial fibrillation (AF), considering the high morbidity and mortality of AF-related ischemic strokes. With the plausible hypothesis that left atrial appendage is the main source of thrombus in AF patients, left atrial appendage closure (LAAC) has been regarded as a potential substitute to oral anticoagulation in order to meet the unmet needs for stroke prevention, particularly in patients with high bleeding risk. Notable advancements in safety, efficacy, and device innovation have been made in recent years, albeit concerns still remain regarding the insufficient efficacy data, device-related complications, and the need for procedural optimization. We aim to review current knowledge about LAAC and provide potential future directions for the remaining key issues.

Abstract
PURPOSE OF REVIEW Intracardiac echocardiography (ICE) has emerged as a powerful imaging tool to guide percutaneous left atrial appendage closure (LAAC). Herein, we review an imaging protocol for ICE-guided LAAC and discuss the evidence for its use. RECENT FINDINGS Standardized imaging protocols have been proposed but have not been fully validated. ICE imaging yields similar procedural and clinical outcomes when compared to transesophageal echocardiography (TEE) to guide LAAC. Despite benefits of avoiding general anesthesia, TEE, and multiple physicians for LAAC procedures, ICE imaging remains under-utilized. Novel ICE catheters with 3D imaging capabilities may improve accuracy and efficiency of LAAC device implantation. ICE guidance is feasible, safe, and effective for LAAC. As the field evolves, further studies will be necessary to assess this technological advancement in imaging guidance.

Abstract
Non-valvular AF is a common clinical condition associated with an increased risk of thromboembolic complications. As a consequence, oral anticoagulant therapy (OAT) is the cornerstone of non-valvular AF management. Despite the well-established efficacy of OAT, many patients cannot receive this preventive therapy due to bleeding or a high risk of bleeding. The fact that more than 90% of thrombi are formed in the left atrial appendage has led to the development of alternative methods to reduce the embolic risk. Left atrial appendage occlusion (LAAO) is a non-pharmacological option for preventing cardioembolic events in patients with non-valvular AF with a contraindication to OAT. The demand for LAAO procedures is growing exponentially and clinicians should consider this alternative option when managing patients with a contraindication to OAT. This review summarises the current thinking about LAAO.

Abstract
BACKGROUND Left atrial appendage occlusion (LAAO) procedures are widely guided by standard transesophageal echocardiography (TEE) probes, requiring general anesthesia in most patients. The use of miniaturized TEE probes allows for LAAO guidance under local anesthesia and offers an attractive imaging alternative to standard TEE probes. OBJECTIVES The aim of this study was to assess the safety and efficacy of miniaturized TEE probes for procedural guidance of LAAO. METHODS Multicenter retrospective observational study of LAAO procedures performed under miniaturized TEE guidance and conscious sedation. The primary efficacy endpoint was technical success. The secondary efficacy endpoint was procedural success (technical success without major periprocedural complications). The safety outcome was a composite of major periprocedural complications. RESULTS A total of 546 consecutive LAAO procedures were performed in 5 European centers. Technical success was achieved in 534 (98.0%) patients. Sixteen major periprocedural complications occurred in 15 (2.9%) patients, yielding a procedural success rate of 97.0%. Conversion to general anesthesia was required in 4 (0.7%) patients. Short-term imaging follow-up was available in 422 patients with an incidence of major (>5 mm) TEE-detected residual leaks of 0.7%, complete LAA occlusion of 82.2% on cardiac computed tomography, and device-related thrombus of 5%. As compared with procedural 2-dimensional imaging for device sizing, preprocedural assessment by 3-dimensional imaging resulted in improved technical success (100% vs 95.0%; P < 0.001). CONCLUSIONS LAAO under conscious sedation and miniaturized TEE guidance is safe and feasible with a high rate of technical success and a low rate of periprocedural complications.

Abstract
BACKGROUND Transesophageal echocardiography (TEE) and cardiac computed tomography angiography (CCTA) are currently utilized for left atrial appendage closure (LAAC) planning. During the recent global iodine contrast media shortage in 2022, cardiac magnetic resonance imaging (CMR) was utilized for the first time for LAAC planning. This study sought to assess the utility of CMR versus TEE for LAAC planning. METHODS This single center retrospective study consisted of all patients who underwent preoperative CMR for LAAC with Watchman FLX or Amplatzer Amulet. Key measures were accuracy of LAA thrombus exclusion, ostial diameter, depth, lobe count, morphology, accuracy of predicted device size, and devices deployed per case. Bland-Altman Analysis was used to compare CMR versus TEE measurements of LAA ostial diameter and depth. RESULTS 25 patients underwent preoperative CMR for LAAC planning. A total of 24 (96%) cases were successfully completed with 1.2 ± 0.5 devices deployed per case. Among the 18 patients who underwent intraoperative TEE, there was no significant difference between CMR versus TEE in LAA thrombus exclusion (CMR 83% vs. TEE 100% cases, p = .229), lobe count (CMR 1.7 ± 0.8 vs. TEE 1.4 ± 0.6, p = .177), morphology (p = .422), and accuracy of predicted device size (CMR 67% vs. TEE 72% cases, p = 1.000). When comparing the difference between CMR and TEE measurements, Bland-Altman analysis demonstrated no significant difference in LAA ostial diameter (CMR-TEE bias 0.7 mm, 95% CI [-1.1, 2.4], p = .420), but LAA depth was significantly larger with CMR versus TEE (CMR-TEE bias 7.4 mm, 95% CI [1.6, 13.2], p = .015). CONCLUSIONS CMR is a promising alternative for LAAC planning in cases where TEE or CCTA are contraindicated or unavailable.
