AIMS: Trans-esophageal echocardiography (TEE) and MDCT currently serve as imaging modalities for left atrial appendage (LAA) occlusion pre-procedural planning. We assessed the feasibility of multi-detector CT (MDCT) based models to predict the correct size of device for LAA occlusion procedures. METHODS AND RESULTS: Patients planned for LAA occlusion underwent MDCT before implantation, which was used for creating and printing 3D LAA models. Three cardiologists evaluated the 3D models and predicted the correct size of the device by manual manipulation, these predictions were compared with the actual device implanted during the procedure...

The recommendations for antithrombotic treatment after left atrial appendage closure (LAAC) remain empirical, and no data exist on the changes in hemostatic markers associated with LACC. The objective of the present study is to determine the presence, degree, and timing of changes in the markers of platelet and coagulation activation after LAAC. Forty-three patients (mean age 76 ± 9 years, 23 men) with atrial fibrillation who underwent successful LACC with the Watchman (n = 27) or Amplatzer Cardiac Plug (n = 16) devices were included in the study...

Percutaneous left atrial appendage (LAA) closure using the WATCHMAN device is a novel option for prevention of stroke associated with atrial fibrillation. However, device-related thrombus (DRT) formation is a concern after WATCHMAN implantation and the predictors of DRT still remain unclear. We aimed to clarify the predictors of DRT after WATCHMAN implantation by analyzing 78 patients (50 males, 72 ± 8 years, average CHA2DS2-VASc score of 4.3 + 1.8) who had undergone WATCHMAN implantation. WATCHMAN was successfully implanted in all patients and four (5%) developed DRT...

We report two cases where left atrial appendage closure (LAA) with Watchman was successfully performed despite presence of definite LAA thrombus. Because there was the risk of thrombus dislodgement, we transiently placed an additional Watchman device in the ascending aorta for embolic protection. © 2017 Wiley Periodicals, Inc.

REVIEW

NOAC therapy has become the standard for stroke prevention in patients with atrial fibrillation. Yet some patients suffer extracranial bleeding events or have other reasons to seek non-pharmacologic stroke protection. LAA occlusion with the WATCHMAN device has been proven safe and effective for such patients and is now recommended in current guidelines for this patient group; other devices also seek approval.

More than 2.3 millions adults in the United States have atrial fibrillation (AF), which exposes them to a 5- fold increased risk of stroke. The left atrial appendage (LAA) appears to be the source of thrombus formation in the vast majority of these patients. Anticoagulation significantly reduces the risk of stroke, but often we encounter patients who have absolute or relative contraindication to anticoagulation. Percutaneous LAA exclusion offers an alternative to anticoagulation to decrease the risk of stroke...

The World Health Organization (WHO) has called for the development and adoption of national plans or strategies to guide public policy and set goals for services, supports, and research related to dementia. It called for distinct populations to be included within national plans, including adults with intellectual disability (ID). Inclusion of this group is important as having Down's syndrome is a significant risk factor for early-onset dementia. Adults with other ID may have specific needs for dementia-related care that, if unmet, can lead to diminished quality of old age...

BACKGROUND: The interventional left atrial appendage (LAA) closure represents an emerging alternative to oral anticoagulation for stroke prevention in certain atrial fibrillation patients. Preliminary results have suggested high procedural success rates and fewer peri-interventional complications; however, there persists an insufficient understanding of the role of many underlying confounding variables (e.g., anatomical characteristics). HYPOTHESIS: It was investigated whether varying LAA morphologies influence procedural success as well as in-hospital outcome...

Atrial fibrillation (AF) remains an important clinical problem with severe complications such as stroke, which especially harms those with risk factors as calculated by the CHADS2 or CHA2DS2-VASc. Until now, no therapy has proven 100% effective against AF. Since the left atrial appendage (LAA) is the most prominent nonvalvular AF-related thromboembolic source and (novel) oral anticoagulant [(N)OAC] carries the hazard of bleeding, LAA occlusion may be an alternative, especially in patients who are ineligible for (N)OAC therapy...

Loneliness is a common experience within long-term care and, to promote well-being and quality of life among people with dementia, it is important to draw upon a repertoire of strategies that provide social stimulation, companionship, and enjoyment. This paper describes and reflects on a program of co-operative social participatory research that sought to introduce football-focused (ie, soccer-based) reminiscence based in 4 community settings within Spain and Scotland. Findings are reported and inform an original conceptual model that supports the introduction of sustainable approaches to the development of football-focused reminiscence with and for people with dementia...

OBJECTIVE: This study sought to identify patient and left atrial morphology specific factors associated with early complications for left atrial appendage occlusion with the Watchman™ (Boston Scientific, Natick, MA) device. BACKGROUND: Oral anticoagulation (OAC) is recommended for patients with atrial fibrillation, however, long-term OAC compliance is poor. In randomized control trials, the Watchman™ device has demonstrated superiority over OAC with warfarin for all cause and cardiovascular mortality and hemorrhagic stroke...

Ischemic stroke is the most common complication of atrial fibrillation (AF). Anticoagulation therapy reduces the risk of systemic embolization in almost all patients with AF irrespective of the type of AF (paroxysmal, persistent or permanent). But, all patients are not suitable candidates for systemic anticoagulation mainly due to the risk of bleeding. Left atrial appendage closure (LAAC) devices have been found to be very effective non-pharmacologic alternative therapy for such patients. There are various types of LAAC devices but United States Food and Drug Administration (US-FDA) have approved only Watchman device...

BACKGROUND: In patients with nonvalvular atrial fibrillation (NVAF), embolic stroke is thought to be associated with left atrial appendage (LAA) thrombi. The WATCHMAN LAA Occlusion Device has been shown to be noninferior to conventional oral anticoagulation with warfarin for stroke prevention in patients with NVAF. This study aimed to evaluate the procedural feasibility, safety and 12-month outcomes of the WATCHMAN LAA Occlusion Device in NVAF patients with high risk for stroke in China...

Left atrial appendage closure (LAAC) is a promising site-directed therapy for stroke prevention in patients with non-valvular atrial fibrillation (AF) who are ineligible or contraindicated for long-term oral anticoagulation. A variety of LAAC modalities are available, including percutaneous endocardial occluder devices such as WATCHMAN(TM) (Boston Scientific Corp., Marlborough, MA, USA), and an ever-increasing body of evidence is helping to define the optimal use of each technique. Similarly increased experience with LAAC has revealed challenges such as device-related thrombi and peri-device leaks for which the long-term significance and appropriate management are areas of active investigation...
