AIMS: Percutaneous left atrial appendage (LAA) occlusion is occasionally incomplete, with residual permeability of the LAA on cardiac computed tomography. The cause for this is unclear. Our objective was to determine if residual permeability was related to incomplete endothelialization. METHODS: A total of 35 consecutive patients contraindicated for anticoagulant therapy admitted for LAA occlusion were included; 12 patients received a Watchman device (Boston Scientific) and 23 patients received an Amplatzer Cardiac Plug (St...

BACKGROUND: Left atrial appendage closure (LAAC) is an efficient alternative of oral anticoagulation to prevent stroke in patients with non-valvular atrial fibrillation (NVAF). Due to complexities of LAA anatomy, a complete closure may not always be obtained with a single device. The aim of this study was to evaluate the feasibility and safety of the staged 'kissing-Watchman' technology to occlude the LAA with complex anatomy. METHODS: In our center, among 300 cases underwent LAAC with Watchman device from February 2012 to December 2016, 7 complex LAAs were implanted double devices using the staged 'kissing-Watchman' technology...

Up to 6.1 million people in the United States have atrial fibrillation (AF), which is associated with an increased risk of stroke. Oral anticoagulants are the mainstay of stroke prevention in AF. For decades, warfarin was the only available drug, fraught with compliance limitations, a narrow therapeutic window, and a high risk of hemorrhage. Pharmacologic developments have produced new anticoagulants that have improved the rates of stroke related to AF; however, they still confer a high risk of bleeding, making them unsuitable for some patients...

BACKGROUND: Left atrial appendage closure (LAAC) for stroke prevention is an increasingly performed intervention. AIMS: This prospective study aims to evaluate the incidence of long-term magnetic resonance imaging (MRI)-detected brain lesions as well as potential changes of neurocognitive function after percutaneous LAAC. METHODS: Brain MRI at 3 T was performed within 24 hr before and after LAAC. A follow-up MRI was carried out after three months...

Background Percutaneous device closure of an ostium secundum atrial septal defect is associated with excellent outcomes and cosmetic results but at the cost of occasional serious and sometimes fatal complications as well as lifelong follow-up. Surgical intervention is required in cases of device-related complications, which carries a slightly higher risk compared to primary closure of an atrial septal defect. We present a surgical perspective of device closure of atrial septal defect. Methods Our database was searched over 4 years for complications related to percutaneous device closure of atrial septal defect, which required surgical retrieval of the device and closure of the defect...

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...

OBJECTIVES: Although percutaneous closure of the left atrial appendage is supported as a potential alternative to lifelong anticoagulation in patients with atrial fibrillation, comprehensive evidence on surgical left atrial appendage closure in heart surgery is limited. METHODS: We conducted a meta-analysis of studies comparing patients who underwent open cardiac surgery with or without left atrial appendage closure. A literature search was performed on PubMed, Embase, and Cochrane Trials databases...

BACKGROUND: Transcatheter left atrial appendage (LAA) occlusion is an alternative strategy for stroke prevention in patients with atrial fibrillation (AF). OBJECTIVES: This study sought to determine the incidence, predictors, and prognosis of thrombus formation on devices in patients with AF who were treated with LAA closure.

PURPOSE: We aimed to evaluate the late clinical outcomes of percutaneous LAA closure in patients with atrial fibrillation (AF) and contraindication to oral anticoagulation. METHODS: Consecutive AF patients with contraindications to oral anticoagulation who underwent successful LAA closure between December 2008 and March 2013 at four centers were included. RESULTS: A total of 101 patients (median age 76 [IQR 69-80] years, 48% women, mean CHA2 DS2 -VASc 5 ± 2; HAS-BLED 4 ± 1) were included...

Aims: Long-term freedom from atrial fibrillation (AF) after catheter ablation (CA) and consequently the potential for stroke reduction remain unpredictable. Percutaneous left atrial appendage closure (LAAC) is an effective mechanical alternative to oral anticoagulation (OAC) for stroke prevention in AF patients. This study aims to evaluate long-term clinical results of combined CA and LAAC in one single procedure. Methods and results: Patients with non-valvular AF who underwent combined CA and LAAC procedure were included in the retrospective compilation of independent prospective general LAAC registries at the individual centres...

BACKGROUND: Percutaneous left atrial appendage (LAA) closure is an emerging option for patients with atrial fibrillation at high risk for cerebrovascular events. The multicenter FLAAC registry (French Nationwide Observational LAA Closure Registry) was established to assess LAA closure outcomes in everyday practice. METHODS AND RESULTS: Four hundred thirty-six patients referred from April 2013 to September 2015 to 33 French interventional cardiology centers for percutaneous LAA closure were included prospectively in the FLAAC registry...

REVIEW

AMPLATZER devices preceded WATCHMAN occluder in 2002 for catheter-based left atrial appendage occlusion. The AMPLATZER technique facilitates simultaneous closure of atrial shunts using two devices through one gear. Randomized WATCHMAN follow-up data showed a mortality benefit over warfarin. AMPLATZER data make this likely valid for the strategy. Particularly young people with atrial fibrillation should be offered left atrial appendage occlusion because the risk is confined to the intervention and early postintervention period...

PURPOSE: The WATCHMAN device for Left Atrial Appendage Occlusion (LAAO) has proven to be an effective alternative to oral anticoagulation (OAC) in patients with atrial fibrillation (AF), and has now been adopted in clinical practice. In the present study, we analyzed the safety and efficacy profile of the LAAO procedure at mid-term follow-up. METHODS: The TRAPS Registry is an observational, multicenter registry involving four Italian centers. Consecutive patients who had undergone LAAO with WATCHMAN device were enrolled...

Atrial fibrillation is commonly coexistent with heart failure, and the management of the heart failure patient would be incomplete without an appreciation for atrial fibrillation management. There are many complications associated with oral anticoagulation in the prevention of stroke related to atrial fibrillation. In recent years, the advent of several percutaneous left atrial appendage (LAA) occlusion/closure strategies has sought to provide an alternative treatment modality. Here, we systematically review the published literature to investigate the efficacy and safety of percutaneous LAA occlusion/closure devices...

Atrial fibrillation is the most common arrhythmia associated with significant mortality and morbidity secondary to thrombo-embolism. To prevent this thrombo-embolism oral anticoagulation therapy is the recommended treatment. In patients with contraindications to oral anticoagulation therapy, percutaneous left atrial appendage occlusion device is indicated. TEE is essential to guide in all the stages of LAA device deployment. Right from pre-procedure screening, to guiding during deployment, to rule out any complications and post-procedure surveillance and monitoring long term outcomes...
