Abstract Background Percutaneous left atrial appendage (LAA) closure may reduce the risk of cardioembolic stroke in patients with non-valvular atrial fibrillation. Given the prophylactic nature of the procedure, identifying and managing complications are paramount. Case summary A 73-year-old man presented 14 months after percutaneous LAA closure with syncope and acute pericardial tamponade which required surgical exploration and haemostasis; the most temporally remote account of this complication albeit amongst very few case reports. Tissue erosion by the Amplatzer™ Amulet™ LAA closure device (Abbott, Plymouth, MN, USA) was noted at two separate anatomical locations, corresponding to the device disc and lobe, which has not been described previously. Discussion This case report highlights the anatomical relationship between the LAA and its surrounding structures, and the importance of recognizing the risk of late device erosion.

Abstract Background Pericardial effusion is a common complication of percutaneous left atrial appendage (LAA) closure. Acute management is the cornerstone of pericardial effusion treatment and interrupting the intervention is often required. Case summary A 65-year-old man presented an acute 10 mm pericardial effusion following pigtail contrast appendage injection. A rapid Watchman Flex 24 mm (Boston Scientific) deployment permitted bleeding interruption. A needle pericardiocentesis was achieved in order to prevent any haemodynamical instability. Discussion This case report describes an atypical cause of pericardial effusion and a technique for bleeding control with LAA closure device deployment.

Abstract Aims  We evaluated the feasibility of left atrial appendage (LAA) closure guided by the image fusion of integrating fluoroscopy into 3D computed tomography (CT). Methods and results  A total of 117 consecutive patients who underwent LAA closure with or without the image fusion were matched (1:2). Each LAA closure step of the Image fusion group was guided by the preprocedure CT and image fusion, especially in the plan of LAA measurement and transseptal puncture. All patients were successfully implanted with a WATCHMAN closure device. Comparing the two groups, the mean number of recapture times and the number of devices per patient of the Image fusion group were significantly lower (0.4 ± 0.5 vs. 0.7 ± 0.8, P = 0.031 and 1.0 ± 0.2 vs. 1.1 ± 0.3, P = 0.027, respectively). The one-time successful deployment rate by the support of the image fusion was higher than in the control group (66.7% vs. 44.9%, P = 0.026). Each case of the Image fusion group was completely occluded with one transseptal puncture, while five of the Non-image fusion group required redo transseptal punctures. During the 45-day follow-up, both group cases presented occlusion efficiency and no major adverse cardiac events were observed. Conclusion  Image fusion technique integrating fluoroscopy into the 3D CT is safe and feasible which can be easily incorporated into the procedural work-flow of percutaneous LAA closure. The fusion image can play an important alternative role in the plan of LAA measurement and transseptal puncture site for improving the LAA closure procedure.

Abstract Background  Left atrial appendage (LAA) closure with the WATCHMAN device is an alternative to anticoagulation therapy for the prevention of stroke in selected patients with atrial fibrillation (AF). Infrequently, left atrial (LA) device-related thrombus formation occurs and it is poorly understood. Thrombus formation due to incomplete covering of the LAA is even rarer and may occur within the first few months after device implantation. Case summary  Here, we present a case of a 68-year-old male patient with permanent AF, drug- and hepatitis induced liver cirrhosis (CILD Score B), and prior aortic valve replacement. The patient had a history of percutaneous LAA closure using a WATCHMAN device. He developed massive peri-device leak and thrombus arising from the space between the device and appendage cleft 2 years after implantation. Because of the high bleeding risk with a HAS-BLED score of 5 points, surgery was chosen as the therapy of choice instead of long-term anticoagulation. The patient was discharged in good clinical condition and has been scheduled for a yearly follow-up. Discussion  This case emphasizes the importance of choosing appropriately sized LAA occluder devices and planning for regular post-interventional follow-ups to minimize the risk of per-device leaks and thrombi.

Introduction: The Transcatheter Leak Closure With Detachable Coils Following Incomplete Left Atrial Appendage Closure Procedures (TREASURE) is a prospective, nonrandomized, single-center study. This study was undertaken to investigate the efficacy of transcatheter leak closure with endovascular coils in patient with incomplete percutaneous/epicardial left atrial appendage (LAA) closure procedures and high thromboembolic (TE)- and bleeding-risk. Hypothesis: We report the efficacy of transcatheter leak closure with endovascular coils in patients with incomplete LAA closure. Methods: Sixty-five consecutive patients with a clinically relevant residual leak (mean age: 72±8 years; 73.8% males; CHA 2 DS 2 -VASc: 4.7±1.1; HAS-BLED: 3.7±0.7) underwent percutaneous closure of the LAA patency via embolization coils. Trans-esophageal echocardiography (TEE) was performed at 60±15 days post-procedure. Results: LAA closure had been previously attempted with a Watchman device in 62 patients, and a LARIAT in 3. Baseline TEE documented a moderate or severe leak in 14 (21.5%) and 51 (78.5%) patients, respectively. Procedure and fluoroscopy times were 69±37min and 22±15min, respectively; the mean volume of iodinated contrast medium used was 82±43mL. Coil deployment was successful in all cases [median n. of coils attempted: 3 (IQR:2-5); median n. of coils deployed: 3 (IQR: 2-4)]. The overall complication rate was 3.1% (1 pericardial tamponade, 1 pericardial effusion). Peri-procedural angiographic and TEE outcomes demonstrated complete obliteration or a negligible residual opacification with a trivial residual jet in 62 cases (95.4%), and a partial occlusion with moderate residual jet in 3 (6.4%). Follow-up TEE after 67±12 days revealed complete LAA sealing or a negligible residual leak in 63 cases (96.9%). Coil deployment led to an average reduction of 90.1% in leak size (p<0.001). After an overall follow-up of 17±4 months, no TE events were documented; 3 patients died from non-cardiovascular and one from cardiovascular causes (heart failure). Conclusions: Transcatheter LAA leak occlusion via endovascular coils appears to be a safe, effective, and promising approach in high TE-risk patients with incomplete LAA closure.

Atrial fibrillation (AF) is an independent risk factor for stroke. Anticoagulation therapy has a risk of intracerebral hemorrhage. The use of percutaneous left atrial appendage (LAA) closure devices is an alternative to anticoagulation therapy. Echocardiography has a leading role in LAA closure procedure in patient selection, during the procedure and during followup. A comprehensive echocardiography study is necessary preprocedural in order to identify all the lobes of the LAA, evaluate the size of the LAA ostium, look for thrombus or spontaneous echo contrast, and evaluate atrial anatomy, including atrial septal defect and patent foramen ovale. Echocardiography is used to identify potential cardiac sources of embolism, such as atrial septal aneurysm, mitral valve disease, and aortic debris. During the LAA occlusion procedure transeosophageal echocardiography provides guidance for the transeptal puncture and monitoring during the release of the closure device. Procedure-related complications can be evaluated and acceptable device release criteria such as proper position and seating of the occluder in the LAA, compression, and stability can be assessed. Postprocedural echocardiography is used for followup to assess the closure of the LAA ostium. This overview paper describes the emerging role of LAA occlusion procedure with transeosophageal echocardiography guidance as an alternative to anticoagulation therapy in patients with AF.

Abstract Background Pulmonary artery (PA) injury is a rarely reported complication following percutaneous left atrial appendage closure (LAAC). This study aims to systematically review all reported cases of PA injury associated with LAAC. Methods PubMed/Medline, SCOPUS, EMBASE, Google Scholar and the MAUDE databases were searched to find studies reporting PA injury during or after LAAC with the Amplatzer Amulet (AA), Amplatzer Cardiac Plug (ACP) or Watchman device through October 2019. Categorical data were reported in terms of numbers and/or percentages (%). Results We found 13 cases (mean age 71.4 yrs) with reported PA injury associated with LAAC. Of these, 9 were case reports, 3 were reported in observational studies, and 1 was in the MAUDE database. Most cases (n=8) were reported in Europe followed by Australia (n=2) and Asia (n=2). The indication for device implantation in all patients was a high bleeding risk with anticoagulation for atrial fibrillation. Five cases were reported with the ACP (1/5 patients died), 5 with AA (2/5 patients died), and 3 with the Watchman (1/2 patients died). Acute and late presentations following implantation were reported for all three devices. 69.2% of cases (9/13) occurred acutely (during or within 24 hours of intervention). Of these, 3/9 occurred during device implantation. 2/4 of the delayed cases occurred &gt;2 weeks following implantation. The mortality rate for acute and delayed cases was 22% (2/9 patients) and 50% (2/4 patients), respectively. A majority of the cases were attributable to barb/strut/hook injury of the PA. PA injury was associated with a mortality rate of approximately 31%. All surviving patients were managed with surgical intervention. Conclusion PA injury is an infrequently reported complication following LAAC and is associated with high mortality. Cases can present acutely (intra-procedurally or within 24 hours) or delayed (&gt;24 hours post-implantation). A majority of cases are due to direct injury of the PA by the struts/hooks/barbs of the device. Practitioners should be cognizant of this life-threatening complication, which requires a high index of suspicion for diagnosis and can occur weeks after device implantation.

BackgroundOptimal preprocedural planning is essential to ensure successful device closure of the left atrial appendage (LAA).DesignThe PREDICT-LAA study is a prospective, international, multicentre, randomised controlled trial (ClinicalTrials.gov NCT04180605). Two hundred patients eligible for LAA closure with an Amplatzer Amulet device (Abbott, USA) will be enrolled in the study. Patients will be allocated to a computational simulation arm (experimental) or standard treatment arm (control) using a 1:1 randomisation. For patients randomised to the computational simulation arm, preprocedural planning will be based on the analysis of cardiac computed tomography (CCT)-based patient-specific computational simulations (FEops HEARTguide, Ghent, Belgium) in order to predict optimal device size and position. For patients in the control arm, preprocedural planning will be based on local practice including CCT analysis. The LAA closure procedure and postprocedural antithrombotic therapy will follow local practice in both arms. The primary endpoint of the study is incomplete LAA closure and device-related thrombus as assessed at 3 months postprocedural CCT. Secondary endpoints encompass procedural efficiency (number of devices used, number of repositioning, procedural time, radiation exposure, contrast dye), procedure-related complications within 7 days postprocedure and a composite of all-cause death and thromboembolic events at 12 months.ConclusionThe objective of the PREDICT-LAA study is to test the hypothesis that a preprocedural planning for LAA closure with the Amplatzer Amulet device based on patient-specific computational simulations can result in a more efficient procedure, optimised procedural outcomes and better clinical outcomes as compared with a standard preprocedural planning.Trial registration numberClinicalTrials.gov Registry (NCT04180605).
