A comparable efficacy and safety between intracardiac echocardiography and transesophageal echocardiography for percutaneous left atrial appendage occlusion

Project description:Background Accumulated clinical studies utilized intracardiac echocardiography (ICE) to guide percutaneous left atrial appendage occlusion (LAAO). However, its procedural success and safety compared to traditional transesophageal echocardiography (TEE) remained elusive. Therefore, we performed a meta-analysis to compare efficacy and safety of ICE and TEE for LAAO. Methods We screened studies from four online databases (including the Cochrane Library, Embase, PubMed, and Web of Science) from their inception to 1 December 2022. We used a random or fixed-effect model to synthesize the clinical outcomes and conducted a subgroup analysis to identify the potential confounding factors. Results A total of twenty eligible studies with 3,610 atrial fibrillation (AF) patients (1,564 patients for ICE and 2,046 patients for TEE) were enrolled. Compared with TEE group, there was no significant difference in procedural success rate [risk ratio (RR) = 1.01; P = 0.171], total procedural time [weighted mean difference (WMD) = −5.58; P = 0.292], contrast volume (WMD = −2.61; P = 0.595), fluoroscopic time (WMD = −0.34; P = 0.705; I2 = 82.80%), procedural complications (RR = 0.82; P = 0.261), and long-term adverse events (RR = 0.86; P = 0.329) in the ICE group. Subgroup analysis revealed that ICE group might be associated with the reduction of contrast use and fluoroscopic time in the hypertension proportion <90 subgroup, with lower total procedure time, contrast volume, and the fluoroscopic time in device type subgroup with multi-seal mechanism, and with the lower contrast use in paroxysmal AF (PAF) proportion ≤50 subgroup. Whereas, ICE group might increase the total procedure time in PAF proportion >50 subgroup and contrast use in multi-center subgroup, respectively. Conclusion Our study suggests that ICE may have comparable efficacy and safety compared to TEE for LAAO.

Left atrial appendage perforation during appendage angiography treated by percutaneous left atrial appendage closure: a case report.

Project description:BackgroundPericardial 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 summaryA 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.DiscussionThis case report describes an atypical cause of pericardial effusion and a technique for bleeding control with LAA closure device deployment.

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.

Periprocedural Pericardial Effusion Complicating Transcatheter Left Atrial Appendage Occlusion: A Report From the NCDR LAAO Registry.

Project description:BackgroundPericardial effusion (PE) is a potential complication of transcatheter left atrial appendage occlusion. The objective of this study was to investigate the incidence, associated characteristics, and outcomes of PE following left atrial appendage occlusion.MethodsPatients in the NCDR LAAO Registry who underwent a Watchman procedure between January 1, 2016 and December 31, 2019 were included. The primary outcome was in-hospital PE requiring intervention (percutaneous drainage or surgery). Odds ratios (ORs) were calculated for adverse event rates associated with PE.ResultsThe study population consisted of 65 355 patients. The mean patient age was 76.2±8.1 years, and the mean CHA2DS2-VASc score was 4.6±1.5. PE occurred in 881 patients (1.35%). Clinical variables independently associated with PE included older age, female sex, left ventricular function, paroxysmal atrial fibrillation, prior bleeding, lower serum albumin, and preprocedural dual antiplatelet therapy; procedural variables included number of delivery sheaths used, sinus rhythm during the procedure, and moderate sedation rather than general anesthesia. PE was associated with increased risk of in-hospital stroke (OR, 6.58 [95% CI, 3.32-13.06]; P<0.0001), death (OR, 56.88 [95% CI, 39.79-81.32]; P<0.0001), and the composite of death, stroke, or systemic embolism (OR, 28.64 [95% CI, 21.24-38.61]; P<0.0001). PE during the index hospitalization was associated with increased risk of death (OR, 3.52 [95% CI, 2.23-5.54]; P<0.0001) and the composite of death, stroke, or systemic embolism (OR, 3.42 [95% CI, 2.31-5.07]; P<0.0001) between discharge and 45-day follow-up.ConclusionsIn-hospital PE during transcatheter left atrial appendage occlusion is infrequent but associated with a substantially higher risk of adverse events, including in-hospital and early postdischarge mortality. Strategies to minimize PE are critical to improve the risk-benefit ratio for this therapy.

Percutaneous left atrial appendage occlusion discrepancy between randomised trials and clinical practice.

Project description:In patients with atrial fibrillation and previous episodes of bleeding on oral anticoagulant treatment, left atrial appendage occlusion (LAAO) has emerged as an alternative way to decrease the risk of stroke.The use of the procedure has been on the rise, and the news coverage has been dominated by an uncritical acceptance of the benefit of this procedure, which probably have contributed to the increasing number of procedures.This commentary is a presentation and critical appraisal of the available evidence on the efficacy and safety of left atrial appendage closure as stroke prophylaxis.We illustrate that LAAO is supported by limited randomised data risk of serious complications, which we do not believe supports the current widespread use.

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

Project description:BackgroundTranscatheter 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 summaryIn this report, we describe a case of peri-Watchman device leak treated successfully with percutaneous device closure using an Amplatzer Vascular Plug II device.DiscussionThe 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.

Intracardiac or transesophageal echocardiography for left atrial appendage occlusion: an updated systematic review and meta-analysis.

Project description:BackgroundIntracardiac echocardiography (ICE) appears to be a potential alternative for percutaneous left atrial appendage occlusion (LAAO) to transesophageal echocardiography (TEE). Thus, a meta-analysis was performed comparing ICE vs. TEE for LAAO guidance.MethodsA comprehensive literature search was performed using MEDLINE, Scopus and Web of Science electronic databases from their inception to November 2023.Results18 studies (124,230 patients) were included. Technical success was higher in ICE- compared to TEE-guidance (OR: 1.36, 95% CI 1.14 to 1.63, p = 0.006) and fewer devices employed (SMD: -0.22, 95% CI -0.43 to -0.01, p = 0.04, I2 = 62%). ICE guidance related with more pericardial effusion/tamponade and iatrogenic residual shunts (logRR: 0.62, 95% CI 0.36 to 0.89, p < 0.001 and RR: 1.53, 95% CI 1.12 to 2.09, p = 0.02, I2 = 1%, respectively). More vascular complications were noted in ICE group (logRR: 0.45, 95% CI 0.11 to 0.78, p = 0.009).ConclusionICE-guided imaging is an effective alternative to TEE in LAAO, as it shows better efficacy than TEE, considering technical success. However, the higher rates of adverse events should be carefully considered.
