Abstract
Left atrial appendage occlusion (LAAO) is rapidly growing as valid stroke prevention therapy in atrial fibrillation. Cardiac imaging plays an instrumental role in preprocedural planning, procedural execution, and postprocedural follow-up. Recently, cardiac computed tomography (CCT) has made significant advancements, resulting in increasing use both preprocedurally and in outpatient follow-up. It provides a noninvasive, high-resolution alternative to the current standard, transesophageal echocardiography, and may display advantages in both the detection and characterization of device-specific complications, such as peridevice leak and device-related thrombosis. The implementation of CCT in the follow-up after LAAO has identified new findings such as hypoattenuated thickening on the atrial device surface and left atrial appendage contrast patency, which are not readily assessable on transesophageal echocardiography. Currently, there is a lack of standardization for acquisition and interpretation of images and consensus on definitions of essential findings on CCT in the postprocedural phase. This paper intends to provide a practical and standardized approach to both acquisition and interpretation of CCT after LAAO based on a comprehensive review of the literature and expert consensus among European and North American interventional and imaging specialists.

Abstract
Oral anticoagulation therapy (OAC) is a mainstay for mitigating stroke and other embolic events in patients with atrial fibrillation (AF). Despite the demonstrated efficacy of OAC in reducing events, many patients are unable to tolerate OAC due to bleeding risks. Left atrial appendage occlusion (LAAO) devices were developed as implantable technologies to moderate stroke risk in patients with intolerance to OAC. Despite clinical data supporting near-comparable protection against thromboembolic events with OAC, device-related thrombus formation has emerged as a critical complication following LAAO that remains a potential limitation to the safety and efficacy of LAAO. Improved biocompatibility of LAAO devices with fluoropolymers, a well-established stent-coating technology used to reduce thrombus formation and promote endothelialization, may optimize outcomes after LAAO.

Abstract
BACKGROUND Left atrial appendage closure (LAAC) is a treatment modality for stroke prevention in patients with atrial fibrillation (AF). One of the potential complications of LAAC is a peri-device leak (PDL), which could potentially increase the risk of thromboembolism formation. METHODS This systematic review was done according to PRISMA guidelines. Using four databases, all primary studies through April 2022 that met selection criteria were included. Outcomes of interest were studies reporting on PDL characteristics, risk factors and management. RESULTS A total of 116 studies met selection criteria (97 original studies and 19 case reports/series). In the original studies (n = 30,133 patients), the weighted mean age was 72.0 ± 7.4 years (57% females) with a HAS-BLED and CHA2DS2-VASc weighted means of 2.8 ± 1.1 and 3.8 ± 1.3, respectively. The most common definition of PDL was based on size; 5 mm: major, 3-5 mm: moderate, < 1 mm minor, or trivial. Follow up time for PDL detection was 7.15 ± 9.0 months. 33% had PDL, irrespective of PDL severity/size, and only 0.9% had PDL of greater than 5 mm. The main risk factors for PDL development included lower degree of over-sizing, lower left ventricular ejection fraction, device/LAA shape mismatch, previous radiofrequency ablation, and male sex. The most common methods to screen for PDL included transesophageal echocardiogram and cardiac CT. PDL Management approaches include Amplatzer Patent Foramen Ovale occluder, Hookless ACP, Amplatzer vascular plug II, embolic coils, and detachable vascular coils; removal or replacement of the device; and left atriotomy. CONCLUSION Following LAAC, the emergence of a PDL is a significant complication to be aware of. Current evidence suggests possible risk factors that are worth assessing in-depth. Additional research is required to assess suitable candidates, timing, and strategies to managing patients with PDL.

Abstract
BACKGROUND The MemoLefort is a new plug occluder for left atrial appendage closure (LAAC) in patients with atrial fibrillation (AF). This study compares the safety and efficacy of MemoLefort and the well-established Watchman occluder for LAAC. METHODS Between January 2021 and September 2022, a cohort of 189 consecutive patients who underwent LAAC with MemoLefort or Watchman at The Second Affiliated Hospital of Wenzhou Medical University were included. Patients with MemoLefort or Watchman devices were compared in terms of the primary safety endpoints encompassing major periprocedural complications and major bleeding events at follow-up, the primary efficacy endpoint of all-cause stroke, systemic embolism and cardiovascular/unexplained death, and the combined hazard endpoint, a composite of all the above-mentioned hazards. RESULTS Of the MemoLefort group (n = 83) and Watchman group (n = 106), the mean age, CHA2DS2-VASc score, and HAS-BLED score were 67.6 ± 9.2 vs. 69.0 ± 10.6 years, 3.9 ± 1.9 vs. 3.8 ± 1.9, and 1.6 ± 1.0 vs. 1.7 ± 1.2, respectively. After a median follow-up duration of 198 (99-329) vs. 334 (171-497) days, the primary endpoints of efficacy [2/49, 4.1% (MemoLefort) vs. 2/97, 2.1% (Watchman); hazard ratio (HR), 1.50; 95% confidence interval (CI), 0.20-11.08; P = 0.68] and safety (1/49, 2.0% vs. 5/97, 5.2%; HR, 0.26; 95% CI, 0.05-1.31; P = 0.19), as well as the combined hazard endpoint (3/49, 61% vs. 6/97, 6.2%; HR, 0.70; 95% CI, 0.18-2.58; P = 0.59) were similar between groups. CONCLUSIONS In the short term, LAAC with MemoLefort provided similar efficacy, safety, and net clinical benefit in comparison to Watchman devices.

Abstract
BACKGROUND In left atrial appendage closure using WATCHMAN FLX, accurate device measurement by transesophageal echocardiography (TEE) is important. We aimed to experimentally validate appropriate methods of device measurement with two-dimensional (2D) and three-dimensional (3D) TEE compared with actual size. METHODS We prepared a full range of device sizes (20, 24, 27, 31, 35 mm), each with five different compression rates. Each device was measured by 2D and 3D TEE at depths of 2, 4, and 6 cm in vitro using inner, outer, and middle line methods. We compared the difference between the actual size by caliper and measurements at each compression rate and depth by the three methods in 2D and 3D TEE. RESULTS A total of 450 patterns of measurements were analyzed. The differences using the middle line method were much less than those using the inner and outer line methods in 2D and 3D TEE (2D TEE: 0.45 ± 0.36 vs. 2.55 ± 0.99 vs. 2.59 ± 0.72 mm, p < 0.01; 3D TEE: 0.34 ± 0.27 vs. 2.38 ± 0.69 vs. 1.86 ± 0.77 mm, p < 0.01). Moreover, the differences in measurements by 3D TEE were more accurate than those of 2D TEE in the inner (2.47 ± 1.86 vs. 1.86 ± 0.77 mm, p < 0.01) and middle (0.58 ± 0.37 vs. 0.34 ± 0.27 mm, p < 0.01) line methods. CONCLUSIONS Middle line method by 3D TEE is the most reliable approach for device measurement at left atrial appendage closure using WATCHMAN FLX device.

Abstract
BACKGROUND Left atrial appendage closure (LAAC) usually requires contrast medium during the procedure. However, patients with chronic kidney disease (CKD) are at high risk of developing contrast nephropathy. This study aimed to assess the safety and feasibility of zero-contrast LAAC in patients with CKD. METHODS AND RESULTS Zero-contrast LAAC was attempted in 15 patients with CKD Stages 3b-5 who were not on hemodialysis. All procedures were performed successfully, without any periprocedural complications. At the 45-day follow-up, no device-related complications or acute kidney disease were observed. CONCLUSIONS The strategy of zero-contrast LAAC in patients with CKD can be an acceptable option.

Abstract
BACKGROUND New and refined catheter based left atrial appendage (LAA) closure devices have been introduced in the past decade. The procedure can be performed using either an endocardial occlusion device or an epicardial loop stitch. We aimed to analyzed recent procedural safety. METHODS Catheter based LAA closures were identified in a complete nationwide German dataset via ICD and OPS codes from 2016 to 2020. RESULTS From 2016 to 2020, 28,039 endocardial and 213 epicardial occlusions were performed. Numbers of endocardial procedures increased from 5259 in 2016 to 5917 in 2020 (p = 0.020) in 387 centers with shifting of patients' characteristics towards older age (β = 0.29, p < 0.001), more heart failure (β = 1.01, p < 0.001) and renal disease (β = 0.67, p = 0.001) and without a significant trend for in-hospital safety except more bleeding (β = 0.12, p = 0.05). In-hospital major adverse cardiac and cerebrovascular events (MACCE) or pericardial puncture were independent on center procedure numbers. The loop stitch procedure was performed in 15 centers. Patients were younger (76.17 ± 8.16 vs. 73.16 ± 8.99, p < 0.001) and had a lower comorbidity index (2.29 ± 1.93 vs. 1.92 ± 1.64, p = 0.005). Adjusted risk difference for pericardial effusion (8.04%; 95% CI 3.01-13.08%; p = 0.002) and pericardial puncture (6.60%; 95% CI 3.85-9.35%; p < 0.001) was higher for the loop stitch procedure, while risk of bleeding (- 1.85%; 95% CI - 3.01 to - 0.69%; p = 0.002), intracerebral bleeding (- 0.37%; 95% CI - 0.59 to - 0.15%; p = 0.001) and shock (- 1.41%; 95% CI - 2.44 to - 0.39%; p = 0.007) was lower. No significant difference was observed for in-hospital MACCE. CONCLUSIONS Endocardial occlusion was the major catheter based LAA closure procedure in Germany without improvements in in-hospital safety from 2016 to 2020. In-hospital MACCE was independent on endocardial LAAC center volumes. Conclusions on the comparison between the two procedure types must be made cautious as the LAA loop stitch occlusion was utilized limited in a minor number of centers.

Abstract
Background The interrelationships between left atrial appendage (LAA) dimensions and device following implantation are unknown. We aimed to analyze the impact of Watchman device implantation on LAA dimensions following its percutaneous closure and potential predictors of remodeling. Methods and Results All consecutive LAA closure procedures performed at 2 centers between November 2017 and December 2020 were included in the WATCH-DUAL (Watchman 2.5 Versus Watchman FLX in a Dual-Center Left Atrial Appendage Closure Cohort) registry. This study included patients who had pre- and postintervention computed tomography scan analysis. The LAA and device dimensions were measured in a centralized core lab by 3-dimensional computed tomography scan reconstruction methods, focusing on the device landing zone. This analysis included 104 patients (age, 76.0 [range, 72.0-83.0] years; 72% men; 53% Watchman FLX; 47% Watchman 2.5). The baseline characteristics were comparable between Watchman 2.5 and Watchman FLX groups, except for the higher use of oversizing in the latter group. The median delay for computed tomography control was 49 (range, 43-64) days. The landing zone area (median, 446 [range, 363-523] versus 290 [222-366] mm2; P<0.001) and minimal diameter (median, 23.0 [range, 20.7-24.8] versus 16.7 [14.7-19.4] mm; P<0.001) significantly increased after implantation. The absolute (median, 157 [range, 98-220] versus 85 [18-148] mm2, P<0.001) and relative (median, 50% [range, 32%-79%] versus 26% [4%-50%]; P<0.001) increases in landing zone area were more pronounced in patients with oversized device. Baseline LAA dimensions were smaller, landing zone eccentricity larger, and oversized device more frequent in patients with significant overexpansion compared with the others. Conclusions LAA dimensions increased at the site of the Watchman prosthesis after implantation, suggesting a local positive remodeling after the procedure. This phenomenon was more pronounced in the case of oversized devices.

Abstract
BACKGROUND The benefit related to the use of preprocedural computed tomography angiography (CCTA) on top of periprocedural echocardiography to plan percutaneous left atrial appendage closure (LAAC) procedures is still unclear. OBJECTIVES The authors sought to evaluate the impact of preprocedural CCTA on LAAC procedural success. METHODS In the investigator-initiated SWISS-APERO (Comparison of Amplatzer Amulet and Watchman Device in Patients Undergoing Left Atrial Appendage Closure) trial, patients undergoing echocardiography-guided LAAC were randomly assigned to receive the Amulet (Abbott) or Watchman 2.5/FLX (Boston Scientific) device across 8 European centers. According to the study protocol ongoing at the time of the procedure, the first operators had (CCTA unblinded group) or did not have (CCTA blinded group) access to preprocedural CCTA images. In this post hoc analysis, we compared blinded vs unblinded procedures in terms of procedural success defined as complete left atrial appendage occlusion as evaluated at the end of LAAC (short-term) or at the 45-day follow-up (long-term) without procedural-related complications. RESULTS Among 219 LAACs preceded by CCTA, 92 (42.1%) and 127 (57.9%) were assigned to the CCTA unblinded and blinded group, respectively. After adjusting for confounders, operator unblinding to preprocedural CCTA remained associated with a higher rate of short-term procedural success (93.5% vs 81.1%; P = 0.009; adjusted OR: 2.76; 95% CI: 1.05-7.29; P = 0.040) and long-term procedural success (83.7% vs 72.4%; P = 0.050; adjusted OR: 2.12; 95% CI: 1.03-4.35; P = 0.041). CONCLUSIONS In a prospective multicenter cohort of clinically indicated echocardiography-guided LAACs, unblinding of the first operators to preprocedural CCTA images was independently associated with a higher rate of both short- and long-term procedural success. Further studies are needed to better evaluate the impact of preprocedural CCTA on clinical outcomes.

Abstract
Left atrial appendage closure aims to eliminate the stasis component of Virchow triad by eliminating a cul-de-sac that favors thrombosis, particularly when atrial contractility becomes inefficient, such as in atrial fibrillation. Left atrial appendage closure devices have a common objective of sealing the appendage completely, with device stability and avoidance of device thrombosis. Two main device designs have been used to perform left atrial appendage closure: those that use a pacifier design (lobe + disk) and those that use a plug (single lobe) design. This review highlights the potential features and benefits of the single-lobe devices.

Abstract
Routine postprocedural imaging with transesophageal echocardiography or cardiac computed tomography angiography is the most commonly used imaging modality for follow-up surveillance usually performed 1 to 6 months after the procedure. Imaging enables recognition of well-suited and sealed devices in the left atrial appendage as well as of potential harmful complications such as peri-device leaks, device-related thrombus, and device embolization, which may lead to further surveillance observation with recurrent imaging, reinitiation of oral anticoagulants, or additional interventional procedures.

Abstract
Atrial fibrillation (AF) is a common heart rhythm disorder that increases the risk of stroke and other cardiovascular complications. The Watchman FLX device is a percutaneous device used for the closure of the left atrial appendage in patients with atrial fibrillation and prevents blood clots from forming, thereby decreasing the risk of stroke. However, device dislodgement during the procedure can occur and compromise the effectiveness of the device. In this case report, we present the experience of an 86-year-old man with a history of atrial fibrillation, coronary artery disease, hypertension, and recent gastrointestinal bleeding due to diverticulosis. During the procedure, the device became dislodged prior to the planned release from the shaft due to the difficult anatomy of the appendage, which caused the operator to over-torque and kink the delivery sheath. The kinked sheath prevented the transmission of torque to the appropriate region of the sheath and caused the device to unscrew prematurely. Fortunately, the device was self-deployed in a satisfactory position, and no further intervention was required. The patient did not experience any complications prior to discharge and follow-up echocardiography showed proper positioning of the device. This case highlights the importance of careful technique during the Watchman FLX procedure and the need to replace the delivery sheath if kinking is noted to prevent unintentional dislodgement of the device. In addition, the case was written with the aid of the artificial intelligence-powered language model ChatGPT and demonstrates its benefits as well as calls for caution while using it for medical writing.

Abstract
BACKGROUND The left atrial appendage (LAA) sealing properties of the Amplatzer Amulet and Watchman FLX devices were compared using cardiac computed tomography (CT) follow-up. METHODS Single-center cohort study of patients undergoing LAAO between 2017 and 2020. Two consecutive cohorts were enrolled, one treated with the Amplatzer Amulet (n = 150) up till 2019, and a second cohort treated with the Watchman FLX (n = 150) device from 2019. Cardiac CT was performed 2 months postprocedure. The primary outcome was complete LAA occlusion defined as no visible peri-device leak (PDL) and absence of contrast patency in the distal LAA. Secondary outcomes included PDL, contrast patency without visible PDL, PDL area, and periprocedural complications. RESULTS Complete occlusion was achieved in 39 (30.5%) of the Amulet group, compared to 89 (71.8%) of the FLX group, p < 0.001. A PDL at the Amulet disc was present in 65 (50.8%), at the lobe in 16 (12.5%), and at both the disc and lobe in 13 (10.2%). For FLX, a PDL was present in 20 (16.1%). Contrast patency without visible PDL was observed in 24 (18.8%) and 15 (12.1%) of the Amulet and FLX group, respectively. The PDL area at the Amulet mid-lobe was 92 mm2 (59-158) and 32 mm2 (IQR 28-96) for FLX, p = 0.019. Device-related thrombosis occurred in 1 (0.7%) and 2 (1.3%), respectively (p = 0.99), with periprocedural adverse events occurring in 6 (4%) and 8 (5.3%) of the Amulet and FLX group (p = 0.79). CONCLUSION Complete LAA occlusion was achieved in a significantly higher proportion treated with the Watchman FLX compared to the Amulet device. PDL was smaller with the FLX than the Amulet. Conceptual device design differences make interpretation of results complex, and additional studies with clinical outcomes are needed.

Abstract
BACKGROUND Data on the safety and efficacy of left atrial appendage occlusion (LAAO) in elderly patients are limited. OBJECTIVES We aimed to compare the outcomes of LAAO between patients ≥80 and <80 years of age. METHODS We included patients enrolled in randomized trials and nonrandomized registries of the Watchman 2.5 device. The primary efficacy endpoint was a composite of cardiovascular/unknown death, stroke, or systemic embolism at 5 years. Secondary endpoints included cardiovascular/unknown death, stroke, systemic embolism, and major and nonprocedural bleeding. Survival analyses were performed using the Kaplan-Meier, Cox proportional hazards, and competing risk analysis methods. Interaction terms were used to compare the 2 age groups. We also estimated the average treatment effect of the device with the use of inverse probability weighting. RESULTS We studied 2,258 patients, of whom 570 (25.2%) were ≥80 years old, and 1,688 (74.8%) were <80 years old. Procedural complications at 7 days were similar in both age groups. The primary endpoint occurred in 12.0% in the device group vs 13.8% in the control group (HR: 0.9; 95% CI: 0.6-1.4) among patients <80 years of age and in 25.3% vs 21.7%, respectively (HR: 1.2; 95% CI: 0.7-2.0) among patients ≥80 (interaction P value = 0.48). There was no interaction between age and treatment effect for any of the secondary outcomes. The average treatment effects of LAAO (compared with warfarin) were similar in the elderly population (compared with younger patients). CONCLUSIONS Despite the higher event rates, octogenarians derive similar benefits from LAAO as their younger counterparts. Age alone should not preclude LAAO in otherwise suitable candidates.

Abstract
Objectives This study aims to evaluate the diagnostic value of real-time four-dimensional transesophageal echocardiography (RT4D-TEE) for implant-related thrombus (IRT). Methods We collected 1,125 patients with atrial fibrillation from May 2019 to February 2022 in our hospital. All patients accepted transesophageal echocardiography (TEE) examination to exclude any thrombi before the LAAC procedure. Results There were 760 patients with LAAC, 66 patients with CIED, and 299 patients without any implantations. A total of 40 patients with an established diagnosis of IRT were further analyzed. The accurate detection rate of IRT by RT4D-TEE was 4.8% (40/826), which was higher than 3.8% (31/826) by 2D-TEE (P = 0.004). No IRT was found on TEE in the rest of the 786 patients. These 40 patients were divided into LAAC (n = 23) and CIED (n = 17) groups according to the results of RT4D-TEE. In the LAAC group, IRT distributed on different parts of the LAA occluder surface, 91.3% (21/23) with clumps of thrombi, and 8.7% (2/23) with a thin layer of thrombi covering the surface of the occluder. In the CIED group, thrombi were seen attached to the leads in the right atrium and right ventricle. The thrombi were beaded in 17.6% (3/17), corded in 17.6% (3/17), and clotted in the remaining 64.7% (11/17) of cases. After adjusting the anticoagulant dosage and following up for 6 months, 20% (8/40) of cases were successfully resolved, 67.5% (27/40) became smaller, and 12.5% (5/40) showed no changes. Conclusion The accurate detection rate of IRT by RT4D-TEE was significantly higher than that by 2D-TEE. 2D-TEE has limitations, but RT4D-TEE can be used as an effective complementary method. Imaging and some clinical features differ significantly between IRT on occluder and IRT on CIED lead.

Abstract
Introduction The Watchman FLX is a novel device for transcatheter left atrial appendage occlusion (LAAO) specifically designed to improve procedural performance in more complex anatomies with a better safety profile. Recently, small prospective non-randomized studies have shown good procedural success and safety compared with previous experiences. Results from large multicenter registries are needed to confirm the safety and efficacy of the Watchman FLX device in a real-world setting. Methods Italian FLX registry is a retrospective, non-randomized, multicentric study across 25 investigational centers in Italy including consecutive patients undergoing LAAO with the Watchman FLX between March 2019 and September 2021 (N = 772). The primary efficacy outcome was the technical success of the LAAO procedure (peri-device flow ≤ 5 mm) as assessed by intra-procedural imaging. The peri-procedural safety outcome was defined as the occurrence of one of the following events within 7 days after the procedure or by hospital discharge: death, stroke, transient ischemic attack, major extracranial bleeding (BARC type 3 or 5), pericardial effusion with tamponade or device embolization. Results A total of 772 patients were enrolled. The mean age was 76 ± 8 with a mean CHA2DS2-VASc score of 4.1 ± 1.4 and a mean HAS-BLED score of 3.7 ± 1.1. Technical success was achieved in 772 (100%) patients with the first device implanted in 760 (98.4%) patients. A peri-procedural safety outcome event occurred in 21 patients (2.7%) with major extracranial bleeding being the most common (1.7%). No device embolization occurred. At discharge 459 patients (59.4%) were treated with dual antiplatelet therapy (DAPT). Conclusions The Italian FLX registry represents the largest multicenter retrospective real-world study reporting periprocedural outcome of LAAO with the Watchman FLX device, resulting in a procedural success rate of 100% and a low incidence of peri-procedural major adverse events (2.7%).

FEops HEARTguide Patient-Specific Computational Simulations for WATCHMAN FLX Left Atrial Appendage Closure: A Retrospective Study. JACC. ADVANCES 2022; 1:100139.

Abstract
Background Three-dimensional transesophageal echocardiography (3D-TEE) is the primary imaging tool for left atrial appendage closure planning. The utility of cardiac computed tomography angiography (CCTA) and patient-specific computational models is unknown. Objectives The purpose of this study was to evaluate the accuracy of the FEops HEARTguide patient-specific computational modeling in predicting appropriate device size, location, and compression of the WATCHMAN FLX compared to intraprocedural 3D-TEE. Methods Patients with both preprocedural and postprocedural CCTA and 3D-TEE imaging of the LAA who received a WATCHMAN FLX left atrial appendage closure device were studied (n = 22). The FEops HEARTguide platform used baseline CCTA imaging to generate a prediction of device size(s), device position(s), and device dimensions. Blinded (without knowledge of implanted device size/position) and unblinded (implant device size/position disclosed) simulations were evaluated. Results In 16 (72.7%) patients, the blind simulation predicted the final implanted device size. In these patients, the 3D-TEE measurements were not significantly different and had excellent correlation (Pearson correlation coefficient (r) ≥ 0.90). No patients had peridevice leak after device implant. In the 6 patients for whom the model did not predict the implanted device size, a larger device size was ultimately implanted as per operator preference. The model measurements of the unblinded patients demonstrated excellent correlation with 3D-TEE. Conclusions This is the first study to demonstrate that the FEops HEARTguide model accurately predicts WATCHMAN FLX device implantation characteristics. Future studies are needed to evaluate if computational modeling can improve confidence in sizing, positioning, and compression of the device without compromising technical success.

Biomedicines 2022; 10:biomedicines10092268. [PMID: 36140368 PMCID: PMC9496262 DOI: 10.3390/biomedicines10092268] [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: 08/11/2022] [Revised: 09/03/2022] [Accepted: 09/09/2022] [Indexed: 11/17/2022] Open
Abstract
Atrial fibrillation (AF), the most common sustained arrhythmia in clinical practice, represents a major cause of morbidity and mortality, with an increasing prevalence. Pharmacologic treatment remains the cornerstone of its management through rhythm and rate control, as well as the prevention of thromboembolism with the use of oral anticoagulants. Recent progress in percutaneous interventional approaches have provided additional options in the therapeutic arsenal, however. The use of the different catheter ablation techniques can now lead to long arrhythmia-free intervals and significantly lower AF burden, thus reducing the rate of its complications. Particularly encouraging evidence is now available for patients with persistent AF or concomitant heart failure, situations in which catheter ablation could even be a first-line option. In the field of stroke prevention, targeting the left atrial appendage with percutaneous device implantation may reduce the risk of thromboembolism to lower rates than that predicted with conventional ischemic risk scores. Left atrial appendage occlusion through the approved Watchman or Amplatzer devices is a well-established, efficacious, and safe method, especially in high-ischemic and bleeding risk patients with contraindications for oral anticoagulation.

Abstract
The placement of a left atrial appendage occlusion (LAAO) device can be a technically challenging transcatheter-based procedure. Key challenges include accurate pre-procedural device sizing and proper device positioning at the LAA ostium to ensure sufficient device anchoring and avoid peri-device leaks. To address these challenges, 3D printing (3DP) of LAA models has recently emerged in the literature, first being described in 2015. We present a review of the benefits and drawbacks of employing this technology for LAAO procedures. Pre-procedurally the use of 3DP can consistently and accurately determine LAAO device size over standard of care approaches. Intra-procedurally 3DP's impact entailed a statistically significant decrease in the number of devices used per procedure, as well as in the fluoroscopic time and dose. Post-procedurally, there is some evidence that 3DP could reduce the rate of peri-device leaks, with limited data on its effect on complication rates. Based on existing evidence, we recommend the focused application of 3DP to cases of complex LAA anatomy and for the training of proceduralists. Lastly, we address the emergence of next generation LAAO devices and AR/VR systems that could limit even this narrow window of clinical benefit afforded by 3DP.

Abstract
BACKGROUND Left atrial appendage occlusion (LAAO) is an alternative to oral anticoagulation (OAC) to decrease the risk of stroke in patients with nonvalvular atrial fibrillation (NVAF); however, certain complications remain a concern. Amplatzer Amulet and Watchman are the two most popular used devices for preventing stroke in patients with NVAF. We assessed the safety and efficacy of LAAO using the Amplatzer Amulet and Watchman. METHODS A meta-analysis was conducted to compare the safety and efficacy outcomes associated with the use of the Amplatzer Amulet and Watchman 2.5. The Newcastle-Ottawa Scale has been utilized to assess the quality of study. RESULTS The meta-analysis includes seven studies involving 2,926 patients (1,418 patients with an amulet and 1,508 with a Watchman 2.5). Generally, adverse event rates for both systems were minimal. No significant differences between the two devices were found in safety (pericardial effusion, device embolization, and cardiac tamponade) or efficacy outcomes (death, TIA, stroke, major/minor bleeding, device leak, and thromboembolic events). CONCLUSIONS The data suggest LAAO is a safe procedure, regardless of which device was used. LAAO devices generally have low complication rates. Outcomes were comparable between the two groups with no significant differences in their safety or efficacy. This article is protected by copyright. All rights reserved.

Abstract
Background Device-associated thrombus are potential causes for thromboembolic events post left atrial appendage closure (LAAC), and correlated with the complete endothelialization of the device surface. Our aim was to evaluate the endothelialization of LAMax LAAC™ occluder surface and analyze the potential influence of the implantation technique on the healing response. Methods A total of 29 healthy dogs (28.0 ± 3.7 kg) were implanted with the devices successfully after ensuring COVER signs was met (Concavity of the disc, Oversizing by 20–50%, Verifying position, Ensuring stability, Residual flow < 5 mm by transesophageal echocardiographic (TEE) examination), and sacrificed at < 24 h, 1-, 2-, 3-, and 6-months. Gross examinations were conducted to evaluate healing response.
Results The mean diameters of LAA orifice measured by angiography and TEE were 19.0 ± 2.9 mm and 16.6 ± 2.9 mm (P < 0.05), respectively. TEE found that the discs in 18 dogs (62.1%) were completely pulled into the LAA with concavity and in 11 dogs incompletely pulled into the LAA with suboptimally concavity, while 5 of them had residual flow. Gross examinations showed that the complete endothelialization on the device surface with concaved disc was found at 1-month after LAAC. Microscopic examinations confirmed complete healing on the device with optimal closure effect. Conclusions The good healing response and the optimal closure effect were observed using the LAMax device in a canine model by following the COVER implantation technique.

Abstract
INTRODUCTION The Watchman-FLX left atrial appendage closure (LAAC) device presents innovative features: higher conformability, reduced length, closed distal "flex-ball" during deployment, and flattened surface. We report our real-world experience with the Watchman-FLX device in two centers with consolidated LAAC expertise. METHODS We enrolled 200 consecutive Watchman-FLX patients (2019-2021) in a nonrandomized double-center registry; procedural data and follow-up for midterm clinical outcomes were collected. A control group of 100 patients treated with first-generation Watchman (2.5) was included. RESULTS According to mean CHAD2 DS2 -VASc (5 ± 1.40) and HAS-BLED (3.8 ± 1.01) scores, the population included in this study was at high risk: 29% had a previous stroke and 56.5% a bleeding event. Main LAAC indications were symptomatic hemorrhage (39.5%), need for triple antithrombotic therapy (39%), gastrointestinal bleeding (32%), and oral anticoagulation intolerance (18%). Transesophageal echocardiography guidance was followed in 93% of cases (48% in general anesthesia and 45% under conscious sedation). Repositioning an FLX device was required in 20% of cases and no complication occurred. In 96% of patients, the first selected device was delivered, while in 4% a device size change was required after the first choice (7% with Watchman 2.5). Peridevice leaks (<5 mm) were found postimplant in two cases (1%). Overall, the procedural success rate was 99.5%. One patient's procedure was unsuccessful (0.5%), due to left atrial appendage (LAA) anatomy; differently, the mean failure rate with Watchman 2.5 was 2%. No device embolization was reported. Complications (8.5%) were mainly related to the access site (3%); major bleedings (1%), and in-hospital death (0.5%) rarely occurred. After a follow-up of 272 ± 173 days, 2.3% of cases experienced a non-device-related stroke and 0.6% fatal bleeding. CONCLUSION Our registry showed a high procedural success rate of the Watchman-FLX in a high-risk population. According to our experience, the main advantages include easy implanting and repositioning, absence of embolization, good LAA sealing, and low rate of complications in the follow-up period.

Novel Computed Tomography Angiography-Based Sizing Methodology for WATCHMAN FLX Device in Left Atrial Appendage Closure. J Cardiovasc Electrophysiol 2022; 33:1781-1787. [PMID: 35586899 DOI: 10.1111/jce.15548] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 02/14/2022] [Accepted: 03/10/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND While there is recent data suggesting an advantage of Computed Tomography Angiography (CTA) over transesophageal echocardiography (TEE) for pre-procedural left atrial appendage closure (LAAC) planning, there is limited published experience for sizing strategies. Device sizing for LAAC may be challenging and non-invasive algorithms that improve this selection process are warranted. OBJECTIVES We sought to evaluate the safety and the feasibility for the implementation of a novel CTA-based sizing methodology for WATCHMAN™ FLX device in a series of patients undergoing LAAC using the TruPlan™ software package. METHODS A prospective analysis of 136 consecutive patients who underwent LAAC over a 12-month period in a single, large academic hospital in the United States was conducted. CTA-guided pre-procedural planning and intracardiac echocardiography (ICE) was performed in all. Procedural success, adverse events, length of procedure, number of devices used, and length of stay were evaluated. RESULTS A total of 136 patients who underwent LAAC procedure with WATCHMAN™ FLX platform between October 1, 2020 until September 30, 2021 were included. The pre-specified protocol using CTA and ICE was implemented in all patients (100%). Mean CHA2 DS2 VASc score was 4.4 ± 1.3 and the mean HAS-BLED score was 3.9 ± 0.8. ICE-guided 100% transseptal puncture success rate was 100% with 98.5% of overall procedural success rate. Pre-procedural CTA sizing strategy accurately predicted the implanted size in 91.1% of patients. Ten patients (7.4%) required another sized device and 2 cases were aborted. At 45-day follow-up, only 1 patient (0.7%) had significant peri-device leak (≥ 5mm) on TEE. CONCLUSIONS CTA-based pre-procedural sizing methodology for WATCHMAN™ FLX in LAAC was safe, feasible and associated with excellent procedural outcomes. Further studies are warranted to confirm if the features specific to TruPlan™ may reduce the number of deployment attempts, the number of devices utilized in the procedure, and the risk of complications.

Abstract
Left atrial appendage closure aims to eliminate the stasis component of Virchow triad by eliminating a cul-de-sac that favors thrombosis, particularly when atrial contractility becomes inefficient, such as in atrial fibrillation. Left atrial appendage closure devices have a common objective of sealing the appendage completely, with device stability and avoidance of device thrombosis. Two main device designs have been used to perform left atrial appendage closure: those that use a pacifier design (lobe + disk) and those that use a plug (single lobe) design. This review highlights the potential features and benefits of the single-lobe devices.

Abstract
Routine postprocedural imaging with transesophageal echocardiography or cardiac computed tomography angiography is the most commonly used imaging modality for follow-up surveillance usually performed 1 to 6 months after the procedure. Imaging enables recognition of well-suited and sealed devices in the left atrial appendage as well as of potential harmful complications such as peri-device leaks, device-related thrombus, and device embolization, which may lead to further surveillance observation with recurrent imaging, reinitiation of oral anticoagulants, or additional interventional procedures.

Comparison in Short-Term Safety and Efficacy between New-Generation WATCHMAN FLX and Conventional WATCHMAN 2.5 for Percutaneous Left Atrial Appendage Closure. J Clin Med 2022; 11:jcm11061618. [PMID: 35329944 PMCID: PMC8949425 DOI: 10.3390/jcm11061618] [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: 02/16/2022] [Revised: 03/07/2022] [Accepted: 03/14/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Percutaneous left atrial appendage closure using the WATCHMAN system, to prevent thrombosis and minimize anti-coagulant use in patients with non-valvular atrial fibrillation, has recently been introduced. The safety and efficacy of new-generation WATCHMAN FLX, as compared to conventional WATCHMAN 2.5, remain unknown. Methods: Consecutive patients who received percutaneous left atrial appendage closure using the WATCHMAN system in our institute, between June 2020 and December 2021, were retrospectively analyzed. Safety and efficacy during the 45-day observational period were compared between the two devices. Results: A total of 93 patients (73.0 ± 7.3 years old, 63 men) who received WATCHMAN FLX (n = 44) or WATCHMAN 2.5 (n = 49) were included. The device implant success rate was 100% in the FLX device group and 98% in the 2.5 device group. There were no procedure-related complications in the FLX group, and one non-relevant pericardial effusion in the 2.5 device group. During the 45-day observational period, there were no procedure-related adverse events. No patients in the FLX group had a peri-device leak >3 mm, whereas two patients in the 2.5 device group had a peri-device leak >3 mm. Anti-coagulants could be terminated in most of the patients (85% versus 88%; p = 0.68). Conclusions: Percutaneous left atrial appendage closure using new-generation WATCHMAN FLX seemed to be as safe and effective as conventional WATCHMAN 2.5 during the short-term observational period.

Abstract
AIMS No studies have compared Watchman 2.5 (W2.5) with Watchman FLX (FLX) devices to date. We aimed at comparing the FLX with W2.5 devices with respect to clinical outcomes, left atrial appendage (LAA) sealing properties and device-related thrombus (DRT). METHODS AND RESULTS All consecutive left atrial appendage closure (LAAC) procedures performed at two European centres between November 2017 and February 2021 were included. Procedure-related complications and net adverse cardiovascular events (NACE) at 6 months after LAAC were recorded. At 45-day computed tomography (CT) follow-up, intra- (IDL) and peri- (PDL) device leak, residual patent neck area (RPNA), and DRT were assessed by a Corelab. Out of 144 LAAC consecutive procedures, 71 and 73 interventions were performed using W2.5 and FLX devices, respectively. There were no differences in terms of procedure-related complications (4.2% vs. 2.7%, P = 0.626). At 45-day CT, the FLX was associated with lower frequency of IDL [21.3% vs. 40.0%; P = 0.032; odds ratio (OR): 0.375; 95% confidence interval (CI): 0.160-0.876; P = 0.024], similar rate of PDL (29.5% vs. 42.0%; P = 0.170), and smaller RPNA [6 (0-36) vs. 40 (6-115) mm2; P = 0.001; OR: 0.240; 95% CI: 0.100-0.577; P = 0.001] compared with the W2.5 group. At 45 days, rate of DRT as detected by CT and/or transoesophageal echocardiography (TOE), was higher with W2.5 (6.0% vs. 0%, P = 0.045). At 6-month follow-up, NACE did not differ between groups. CONCLUSIONS In this cohort of consecutive LAACs, FLX as compared to W2.5, was associated with similar procedure-related complications and 6-month NACE, but with improved LAA neck coverage, and lower IDL and DRT.

The ALSTER-FLX Registry: 3-month outcomes following left atrial appendage occlusion employing a next-generation device, a matched-pair-analysis to EWOLUTION. Heart Rhythm 2022; 19:917-926. [PMID: 35181483 DOI: 10.1016/j.hrthm.2022.02.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 02/09/2022] [Accepted: 02/09/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND The new generation WATCHMAN FLX device for left atrial appendage occlusion has been modified in various aspects to improve procedural results. No comparison of the WATCHMAN FLX to the previous WATCHMAN device is available. OBJECTIVES We aimed to compare procedural results with WATCHMAN FLX in patients on dual antiplatelet therapy at around three months to data with WATCHMAN (EWOLUTION registry). METHODS 164 consecutive patients receiving the WATCHMAN FLX device in four European centers were included in the retrospective ALSTER FLX registry. As a control-group for a matched-pair-analysis, 1020 patients treated with the WATCHMAN device and data up to first follow-up (around three months) from the EWOLUTION registry were used. RESULTS Implantation was successful in all ALSTER FLX patients (100%) and similar to results in EWOLUTION (99%, p=0.2). We observed no stroke or device embolization in ALSTER FLX, similar to EWOLUTION (stroke 0.5%, device embolization 0.4%) at three months. Numerically less ALSTER FLX patients (2.4%) developed a device associated thrombus (DAT) compared to 3.7% EWOLUTION patients, yet without reaching statistical significance after matching (DAT pairwise event-difference median, 95% confidence interval 2(0/6), p=0.1). WATCHMAN FLX implantation was associated with a significant higher sealing rate compared to EWOLUTION at three months (ALSTER FLX 90% vs. EWOLUTION 79.4%, p=0.039 after matching). Major non-procedural bleeding events and mortality were similar after matching (event difference for bleeding 0(-3/3), p=0.6; death (1(-2/4), p=0.3). CONCLUSIONS Periprocedural, early 3-months outcomes with WATCHMAN FLX demonstrate a similar safety profile and an improved sealing rate compared to the WATCHMAN device.

Abstract
BACKGROUND The Watchman FLX is a device upgrade of the Watchman 2.5 that incorporates several design enhancements intended to simplify left atrial appendage occlusion (LAAO) and improve procedural outcomes. This study compares peri-procedural results of LAAO with Watchman FLX (Boston Scientific, Marlborough, Massachusetts) in centers with varying degrees of experience with the Watchman 2.5 and Watchman FLX. METHODS Prospective, multicenter, "real-world" registry including consecutive patients undergoing LAAO with the Watchman FLX at 26 Spanish sites (FLX-SPA registry). Implanting centers were classified according to the center's prior experience with the Watchman 2.5. A further division of centers according to whether or not they had performed ≤ 10 or > 10Watchman FLX implants was prespecified at the beginning of the study. Procedural outcomes of institutions stratified according to their experience with the Watchman 2.5 and FLX devices were compared. RESULTS 359 patients [mean age 75.5 (SD8.1), CHA2DS2-VASc 4.4 (SD1.4), HAS-BLED 3.8(SD0.9)] were included. Global success rate was 98.6%, successful LAAO with the first selected device size was achieved in 95.5% patients and the device was implanted at first attempt in 78.6% cases. There were only 9(2.5%) major peri-procedural complications. No differences in efficacy or safety results according to the centeŕs previous experience with Watchman 2.5 and procedural volume with Watchman FLX existed. CONCLUSIONS The Watchman FLX attains high procedural success rates with complete LAA sealing in unselected, real-world patients, along with a low incidence of peri-procedural complications, regardless of operatoŕs experience with its previous device iteration or the number of Watchman FLX devices implanted.

Abstract
BACKGROUND Residual peri-device leakage (PDL) is frequent after left atrial appendage occlusion (LAAO). Little is known about management strategies, procedural aspects and outcomes of interventional PDL closure. AIMS The aim of this study was to assess the safety and feasibility of PDL closure after LAAO. METHODS Fifteen centres contributed data on baseline characteristics, in-hospital and follow-up outcomes of patients who underwent PDL closure after LAAO. Outcomes of interest included acute success and complication rates and long-term efficacy of the procedure. RESULTS A total of 95 patients were included and a cumulative number of 104 leaks were closed. The majority of PDLs were detected within 90 days (range 41-231). Detachable coils were the most frequent approach (42.3%), followed by the use of the AMPLATZER Vascular Plug II (29.8%) and the AMPLATZER Duct Occluder II (17.3%). Technical success was 100% with 94.2% of devices placed successfully within the first attempt. There were no major complications requiring surgical or transcatheter interventions. During follow-up (96 days [range 49-526]), persistent leaks were found in 18 patients (18.9%), yielding a functional success rate of 82.7%, although PDLs were significantly reduced in size (pre-leak sizemax: 6.1±3.6 mm vs post-leak sizemax: 2.5±1.3 mm, p<0.001). None of the patients had a leak >5 mm. Major adverse events during follow-up occurred in 5 patients (2 ischaemic strokes, 2 intracranial haemorrhages, and 1 major gastrointestinal bleeding). CONCLUSIONS Several interventional techniques have become available to achieve PDL closure. They are associated with high technical and functional success and low complication rates.

Abstract
OBJECTIVE The aim of this study was to assess temporal changes and clinical implications of peridevice leak (PDL) after left atrial appendage closure. BACKGROUND Endocardial left atrial appendage closure devices are alternatives to long-term oral anticoagulation (OAC) for patients with atrial fibrillation. PDL > 5 mm may prohibit discontinuation of OAC. METHODS Patients included in the study had: 1) successful Watchman device implantation without immediate PDL; 2) new PDL identified at 45 to 90 days using transesophageal echocardiography; 3) eligibility for OAC; and 4) 1 follow-up transesophageal echocardiographic study for PDL surveillance. Relevant clinical and imaging data were collected by chart review. The combined primary outcome included failure to stop OAC after 45 to 90 days, transient ischemic attack or stroke, device-related thrombi, and need for PDL closure. RESULTS Relevant data were reviewed for 1,039 successful Watchman device implantations. One hundred eight patients (10.5%) met the inclusion criteria. The average PDL at 45 to 90 days was 3.2 ± 1.6 mm. On the basis of a median PDL of 3 mm, patients were separated into ≤3 mm (n = 73) and >3 mm (n = 35) groups. In the ≤3 mm group, PDL regressed significantly (2.2 ± 0.8 mm vs 1.6 ± 1.4 mm; P = 0.002) after 275 ± 125 days. In the >3 mm group, there was no significant change in PDL (4.9 ± 1.4 mm vs 4.0 ± 3.0 mm; P = 0.12) after 208 ± 137 days. The primary outcome occurred more frequently (69% vs 34%; P = 0.002) in the >3 mm group. The incidence of transient ischemic attack or stroke in patients with PDL was significantly higher compared with patients without PDL, irrespective of PDL size. CONCLUSIONS New PDL detected by transesophageal echocardiography at 45 to 90 days occurred in a significant percentage of patients and was associated with worse clinical outcomes. PDL ≤ 3 mm tended to regress over time.

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
BACKGROUND Device-related thrombus (DRT) has been considered an Achilles' heel of left atrial appendage occlusion (LAAO). However, data on DRT prediction remain limited. OBJECTIVES This study constructed a DRT registry via a multicenter collaboration aimed to assess outcomes and predictors of DRT. METHODS Thirty-seven international centers contributed LAAO cases with and without DRT (device-matched and temporally related to the DRT cases). This study described the management patterns and mid-term outcomes of DRT and assessed patient and procedural predictors of DRT. RESULTS A total of 711 patients (237 with and 474 without DRT) were included. Follow-up duration was similar in the DRT and no-DRT groups, median 1.8 years (interquartile range: 0.9-3.0 years) versus 1.6 years (interquartile range: 1.0-2.9 years), respectively (P = 0.76). DRTs were detected between days 0 to 45, 45 to 180, 180 to 365, and >365 in 24.9%, 38.8%, 16.0%, and 20.3% of patients. DRT presence was associated with a higher risk of the composite endpoint of death, ischemic stroke, or systemic embolization (HR: 2.37; 95% CI, 1.58-3.56; P < 0.001) driven by ischemic stroke (HR: 3.49; 95% CI: 1.35-9.00; P = 0.01). At last known follow-up, 25.3% of patients had DRT. Discharge medications after LAAO did not have an impact on DRT. Multivariable analysis identified 5 DRT risk factors: hypercoagulability disorder (odds ratio [OR]: 17.50; 95% CI: 3.39-90.45), pericardial effusion (OR: 13.45; 95% CI: 1.46-123.52), renal insufficiency (OR: 4.02; 95% CI: 1.22-13.25), implantation depth >10 mm from the pulmonary vein limbus (OR: 2.41; 95% CI: 1.57-3.69), and non-paroxysmal atrial fibrillation (OR: 1.90; 95% CI: 1.22-2.97). Following conversion to risk factor points, patients with ≥2 risk points for DRT had a 2.1-fold increased risk of DRT compared with those without any risk factors. CONCLUSIONS DRT after LAAO is associated with ischemic events. Patient- and procedure-specific factors are associated with the risk of DRT and may aid in risk stratification of patients referred for LAAO.

Abstract
Percutaneous mechanical closure of the left atrial appendage (LAA) is a valuable stroke prevention strategy in patients with atrial fibrillation and contraindication to oral anticoagulation. LAA thrombus is a common finding in patients with atrial fibrillation and frequently fails to resolve despite therapeutic anticoagulation. In this scenario, LAA occlusion device implant is generally discouraged due to the high risk of thrombus dislodgement and embolization; however, alternative management options are limited. We report the first case of a successful LAA occlusion device (Watchman-FLX) implant in the presence of a proximal thrombus.
