Case report: percutaneous closure of residual leak following left atrial appendage occlusion.

ABSTRACT:

Background

Transcatheter left atrial appendage occlusion (LAAO) using Watchman device has been demonstrated to be efficacious in decreasing stroke risk in patients with atrial fibrillation who are not suitable for long-term anticoagulation. Residual leaks are frequently encountered following LAAO procedures and their clinical implications and optimal management remain controversial.

Case summary

In this report, we describe a case of peri-Watchman device leak treated successfully with percutaneous device closure using an Amplatzer Vascular Plug II device.

Discussion

The clinical implications of peri-device leaks remain controversial with general consensus to continue anticoagulation along with serial imaging for larger leaks (>5 mm). As an alternative strategy, percutaneous closure of these leaks has been attempted in hope of avoiding anticoagulation and minimizing the risk of stroke and should be studied further.

Frailty in patients undergoing percutaneous left atrial appendage closure.

Project description:BackgroundFrailty is associated with significant morbidity and mortality in older adults. Whether frailty predicts adverse outcomes after percutaneous left atrial appendage closure (LAAC) remains uncertain.ObjectiveThe purpose of this study was to examine the association between frailty and clinical outcomes after percutaneous LAAC.MethodsWe identified patients 65 years and older in Medicare fee-for-service claims who underwent LAAC between October 1, 2016, and December 31, 2019. Patients were identified as frail on the basis of the Hospital Frailty Risk Score (HFRS), a validated frailty measure centered on health resource utilization, with the cohort stratified into low (<5), intermediate (5-15), and high (>15) risk groups.ResultsOf the 21,787 patients who underwent LAAC, 10,740 (49.3%) were considered frail (HFRS >5), including 3441 (15.8%) in the high-risk group. The mortality rate (up to 1095 days) were 16.1% in the low-risk group, 26.7% in the intermediate-risk group, and 41.1% in the high-risk group (P < .001). After adjusting for age, sex, and comorbidities, HFRS >15 (compared with HFRS <5) was associated with a higher risk of long hospital stay (odds ratio [OR] 8.29; 95% confidence interval [CI] 5.94-11.57), 30-day readmission (OR 1.80, 95% CI 1.58-2.05), 30-day mortality (OR 5.68, 95% CI 3.40-9.40), and 1-year mortality (OR 2.83, 95% CI 2.39-3.35). In restricted cubic spline models, the adjusted OR for all outcomes monotonically increased with increasing HFRS.ConclusionFrailty is common in patients undergoing LAAC and is associated with increased risks of long hospital stay, readmissions, and short-term mortality.

Percutaneous left atrial appendage closure: beyond the classic indications.

Project description:Percutaneous left atrial appendage closure (LAAC) has proven to be an effective alternative to oral anticoagulation (OAC) for stroke prevention in patients with non-valvular atrial fibrillation (NVAF). International guidelines traditionally recommend LAAC for NVAF patients at high thromboembolic risk and contraindication to or at high risk for OAC. However, there are many other clinical situations in which this procedure may also be beneficial. This paper discusses the potential role of LAAC in specific haemorrhagic diseases (cerebral amyloid angiopathy, age-related macular degeneration, hereditary haemorrhagic telangiectasia, and Moyamoya disease), after left atrial appendage (LAA) electrical isolation, in cases of persistent thrombus inside the LAA, in end-stage renal disease and in special groups of patients for whom low compliance and persistence to OAC may be anticipated.

Percutaneous left atrial appendage closure in a patient with haemophilia and atrial fibrillation: a case report.

Project description:BackgroundAtrial fibrillation (AF) is the most common cardiac arrhythmia and is a major cause of embolic stroke. In patients with hereditary bleeding disorders such as haemophilia, management of AF particularly anticoagulation can be quite challenging. Left atrial appendage (LAA) closure is an emerging option in AF patients who are not eligible for oral anticoagulation therapy because of contraindications or high bleeding risk.Case summaryA 67-year-old man with permanent AF and haemophilia was referred for further evaluation of our cardiology clinic by his primary haematologist. The CHA2DS2-VASc score was estimated to be 3 and the HAS-BLED score was 3. Due to high risk of bleeding, we decided to perform percutaneous LAA closure instead of oral anticoagulation. Pre-procedural cardiac computerized tomography angiography and transoesophageal echocardiography were performed for measurements of LAA dimensions and exclude LAA thrombus. Percutaneous LAA occlusion was performed using a 28-mm AmplatzerTM AmuletTM device. The final result was excellent without significant residual leak, pericardial effusion, and embolic complication. Clopidogrel 75?mg/day and aspirin 81?mg/day for 1?month with adequate FVIII prophylaxis and then only aspirin 81?mg/day for 2 months were recommended. No antiplatelet was given after 3 months. The patient did not report any thrombotic or haemorrhagic adverse events and there were no complications related to implanted device after 1 year of follow-up.DiscussionIn patients with hereditary bleeding disorders such as haemophilia, management of AF particularly anticoagulation can be quite challenging. In this report, we present a case of percutaneous LAA occlusion using AmplatzerTM AmuletTM device in a patient who has haemophilia and permanent AF. LAA closure has the potential to be more cost effective as compared to oral anticoagulation therapy due to lesser necessity of clotting factor infusion.

Temporal changes and clinical significance of peridevice leak following left atrial appendage occlusion with Amplatzer devices.

Project description:BackgroundThe natural history of peridevice leak (PDL) following left atrial appendage occlusion (LAAO) is unknown. This study sought to investigate changes of PDL from 2 until 12 months after LAAO, using cardiac computed tomography (CT), and to assess the potential association between persistent PDL and clinical outcomes METHODS: Single-center observational study of Amplatzer LAAO implants between 2010 and 2017 (n = 206). Patients with 2 and 12 months cardiac CT were included in the study (n = 153). Images were blindly analyzed. PDL was characterized by frequency and size at the device disc, lobe, and left atrial appendage contrast patency. Patients were followed for the composite outcome of ischemic stroke, transient ischemic attack, systemic embolism, or all-cause death. Median follow up from LAAO was 3.1 (2.3-4.3) years.ResultsContrast patency was present in 101 (66%) and 72 (47%) (p < 0.001) at 2 and 12 months, respectively. PDL was identified at the disc in 103 (67%) patients at 2 months versus 93 (61%) at 12 months (p = 0.08), and at the lobe in 29 (19%) at both time points. PDL area at the disc did not change significantly over time, ∆$\unicode{x02206}$ area: -8.95 mm (95% confidence interval [CI]: -18.9; 1.01) p = 0.08. Permanent atrial fibrillation was independently associated with persistent PDL. Persistent versus no PDL was associated with a 62% worse clinical outcome, however not statistically significant, hazard ratio (HR): 1.62 (95% CI: 0.9-2.93), p = 0.11.ConclusionPersistent PDL was frequently observed following LAAO with Amplatzer devices. The PDL frequency and size appeared unchanged between 2 and 12 months. Persistent PDL was not significantly associated with worse clinical outcomes, yet this needs further delineation in future studies.

Percutaneous left atrial appendage closure using the LAmbre device in patients with atrial fibrillation and left atrial appendage thrombus.

Project description:BackgroundLeft atrial appendage closure (LAAC) is considered a valid alternative for the prevention of thromboembolic stroke in patients with persistent left atrial appendage thrombus (LAAT) despite adequate anticoagulation. However, the data on LAAC using the LAmbre device for patients with LAAT is limited. This study was performed to explore efficacy and safety as well as to share the experience of the modified LAAC procedure with the LAmbre device.Materials and methodsA total of 7 patients with persistent LAAT despite adequate anticoagulation underwent modified LAAC with the LAmbre device between November 2019 and April 2022. Transesophageal echocardiography was performed 3 months postoperatively to detect device-related thrombosis and peridevice leak. The patients' clinical events were evaluated during the perioperative and follow-up periods.ResultsThe median age, CHA2DS2-VASc score, and HAS-BLED score of all patients were 71 [53-73], 3 [2-4], and 2 [2-3], respectively. In the procedure, a cerebral protection system was used in two patients. LAAC with the LAmbre device was successfully performed in all patients without perioperative events. During the median follow-up of 383 [325-865] days, postoperative transesophageal echocardiography was performed in six (85.7%) patients. Device-related thrombosis was detected in one (16.7%) patient, and no significant peridevice leak was observed. No thromboembolic event or bleeding event occurred in any patients.ConclusionLAAC with the LAmbre device is effective and safe when performed by experienced operators in highly selected patients with LAAT after adequate anticoagulation.

Percutaneous Left Atrial Appendage Occlusion: A View From the UK.

Project description:AF is associated with an increased risk of thromboembolic events, which is usually managed with oral anticoagulation therapy. However, despite a broad range of anticoagulant options and improved uptake in anticoagulation over the past decade, there are some limitations to this approach. Percutaneous left atrial appendage occlusion has been shown to be an effective alternative in this setting, and population data suggest a clear demand for this procedure. Over the past decade, several important changes to the commissioning and delivery of this service have occurred in the UK. In this article, the authors describe the use of percutaneous left atrial appendage occlusion in the UK and discuss the challenges that lie ahead.

Percutaneous Closure of Left Atrial Appendage significantly affects Lipidome Metabolism.

Project description:Patients with non-valvular atrial fibrillation (AF) and a high risk for oral anticoagulation can be treated by percutaneous implantation of left atrial appendage occlusion devices (LAAC) to reduce the risk of cardio-embolic stroke. This study evaluates whether LAAC may influence lipid metabolism, which has never been investigated before. Patients with successful LAAC were included consecutively. Venous peripheral blood samples of patients were collected immediately before (T0, baseline) and 6 months after (T1, mid-term) LAAC. A targeted metabolomics approach based on electrospray ionization liquid chromatography-mass spectrometry (ESI-LC-MS/MS) and MS/MS measurements was performed. A total of 34 lipids revealed a significant change from baseline to mid-term follow-up after successful LAAC. Subgroup analysis revealed confounding influence by gender, age, diabetes mellitus type II, body mass index, left ventricular ejection fraction, creatinine and NT-proBNP. After multivariable adjustment within logistic regression models, these 34 lipids were still significantly altered after LAAC. Successful percutaneous LAAC may affect lipid metabolism and thereby may potentially affect pro-atherogenic and cardio-toxic effects.

Case report: peri-device leakage after percutaneous left atrial appendage occlusion: plug, clip, or amputate?

Project description:Abstract Background Although peri-device leakage is frequently observed after left atrial appendage occlusion (LAAO), there is no consensus on the optimal management strategy. It is unknown whether additional plugging should be preferred over surgical exclusion of the LAA, as experience with additional plugging is limited. Case summary In this case report, we demonstrate the clinical implications of additional plugging and surgical exclusion in a 65-year-old male patient with peri-device leakage and recurrent thromboembolic events. After the recurrence of paroxysmal atrial fibrillation (AF) and a transient ischaemic attack despite adequate anticoagulation, the patient was opted for re-do pulmonary vein isolation and LAAO with a Watchman device. Due to multiple ischaemic strokes and recurrent AF in combination with significant peri-device leakage, additional plugging with a second device was performed. Post-procedurally, the patient had another ischaemic stroke and persisting peri-device leakage was observed during follow-up. Due to progressive symptoms of AF and patient’s preference to discontinue DOAC, he underwent a Cox MAZE IV procedure, including amputation of the LAA with both devices. Within six months after surgery, the patient experienced two more ischaemic events. In the following two years, the patient remained free of any cerebrovascular accidents or recurrence of AF. Discussion Additional plugging of peri-device leakage is not always successful in stroke prevention. In combination with recurrent AF, progressive symptoms, contraindication for oral anticoagulation, and patient’s preference, surgical LAA exclusion could be preferred over additional plugging.
