INTRODUCTION: Left atrial appendage (LAA) closure has become of major interest for patients with atrial fibrillation intolerant to oral anticoagulation therapy (OAC). Patients with a contraindication to both OAC and antiplatelet therapy are not eligible for percutaneous LAA closure. We aimed to find an alternative treatment for these specific patients. METHODS: From March 2014 until December 2015 five patients were referred for percutaneous LAA closure. Alternative treatment was necessary due to an absolute contraindication to OAC and antiplatelet therapy (n = 4) or after previous failed percutaneous device implantation (n = 1)...

The relationship of stroke and atrial fibrillation seems to become more complex as we gain more knowledge of the issue. Recent studies have questioned the temporal relationship between the two, which also questions causation. Left atrial appendage closure is an attractive, but unproven technology when compared with the 50-year experience with warfarin. In a patient who is on warfarin and having no issues with bleeding, medication intolerance, or lack of efficacy, it is difficult to justify stopping the drug and placing a closure device as sole therapy to prevent a stroke...

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...

Oral anticoagulant therapy (OAT) is a mainstay of atrial fibrillation (AF) pharmacological treatment. Left atrial appendage closure is a possible treatment, when feasible, in patients with intracerebral hemorrhage during OAT. We report a case of right atrial appendage thrombosis in a patient with chronic AF admitted for syncope due to diuretic-induced orthostatic hypotension. Two years previously, he had undergone left atrial appendage closure with the Amplatzer Cardiac Plug device because of intracerebral hemorrhage during OAT...

OBJECTIVES: Occlusion of the left atrial appendage (LAA) has become an integral and important part of the surgical treatment of atrial fibrillation. Different methods of surgical occlusion of the LAA have been associated with varying levels of short- and long-term success for closure. The purpose of this study was to evaluate long-term results of epicardial placement and endocardial occlusion in patients undergoing cardiac operative procedures. METHODS: A total of 101 patients (average age 65...

Percutaneous left atrial appendage (LAA) closure is currently utilized for the prophylaxis of thromboembolic cerebrovascular accidents in patients with non-valvular atrial fibrillation. The presence of LAA thrombus is usually considered a contraindication for the procedure, since there is a high risk of thrombus embolization. While reports in the literature have shown the feasibility of LAA closure in the presence of LAA thrombus with certain cerebral embolic protection devices, we present the first-in-man LAA closure of a patient with LAA thrombus using the TriGuard Embolic Protection Device...

BACKGROUND A free-floating ball thrombus in the left atrium is a rare clinical condition. However, the diagnosis of this condition has been facilitated by the advent and development of echocardiography and multi-detector row computed tomography (MDCT) and several cases have been reported. CASE REPORT We report a case of a 75-year-old woman who had recurrent giant spherical thrombi in the left atrium. She was diagnosed with chronic atrial fibrillation at 52 years of age. A pacemaker implantation was performed at 54 years of age because of a complete atrioventricular block; and mitral valve replacement was performed for severe mitral regurgitation at 62 years of age...

Rhinophyma is considered the end stage in the development of rosacea, accompanied by hypertrophy of the sebaceous glands, which causes an enlargement of the nose. It is an uncommon condition that often results in both functional and cosmetic impairment. A large variety of surgical and nonsurgical treatments have been published to treat it. Closure is usually obtained by wound granulating in by secondary intention, skin grafting or local flaps. Rarely these lesions can attain a giant size and pose a challenge in surgical treatment...

Mesenchymal stem cells (MSCs) can affect the microenvironment of a wound and thereby accelerate wound healing. Wnt proteins act as key mediators of skin development and participate in the formation of skin appendages such as hair. The mechanisms of action of MSCs and Wnt proteins on skin wounds are largely unknown. Here, we prepared a Wnt7a-containing conditioned medium (Wnt-CM) from the supernatant of cultured human umbilical cord-MSCs (UC-MSCs) overexpressing Wnt7a in order to examine the effects of this CM on cutaneous healing...

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...

Non-valvular atrial fibrillation is associated with a significantly increased risk of embolic stroke due to blood clot forming predominantly in the left atrial appendage (LAA). Preventive measures to avoid embolic events are permanent administration of anticoagulants or surgical closure of the LAA. Various clinical trials provide evidence about safety, effectiveness and therapeutic success of LAA occlusion using various cardiac occluder devices. The use of such implants for interventional closure of the LAA is likely to become a valuable alternative for stroke prevention, especially in patients with contraindication for oral anticoagulation as safety, clinical benefit and cost-effectiveness of LAA occlusion has recently been demonstrated...

Ischemic stroke is a common complication of atrial fibrillation. Currently, oral anticoagulant drugs are the most commonly used method of stroke prevention. Left atrial appendage occlusion is thought to be the main source of thrombi in patients with AF. Percutaneous left atrial appendage is a valuable therapeutic option for selected high-risk patients with AF and contraindications for oral anticoagulation therapy. While complete closure of the left atrial appendage is the goal of a device implantation the variable nature of the left atrial appendage anatomy makes this goal difficult to achieve...

Atrial fibrillation (AF) is the most common cardiac arrhythmia, occurring in 1%-2% of the general population. An important aspect is the treatment of AF in terms of stroke prevention. In patients with absolute contraindication to long-term anticoagulation due to high bleeding risk, a valuable alternative exists in left atrial appendage (LAA) closure. Unfortunately, thrombus in the LAA is a contraindication to the procedure because of high risk of embolization. We describe a clinical case with permanent AF, absolute contraindication to long-term anticoagulation therapy, and persistent thrombus formation in the LAA that was treated with transcatheter LAA closure and supraaortic trunk protection system in order to avoid risk of periprocedural stroke...

We present the case of a patient with a high-output fistula between the right superficial femoral artery and femoral vein after left atrial appendage closure successfully treated with a PK-Papyrus covered coronary stent using a 6F guiding catheter. To the best of our knowledge this is the first time a PK-Papyrus coronary stent has been used in this setting.

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...

The rapidity with which epithelial cells cover a wound surface helps determine whether scarring or scar-less healing results. As methylene blue is a vital dye that is absorbed by damaged tissue but not undamaged epidermis, it can be used to assess wound closure. We sought to develop a quantitative methylene blue exclusion assay to estimate the timeframe for re-epithelialization in regenerating appendages in zebrafish and axolotls, two classic model systems of regeneration. Following application of methylene blue to the amputation plane and extensive washing, the regenerating tail was imaged in vivo until staining was no longer visible...

INTRODUCTION: Atrial fibrillation (AFib) is related to a high risk of stroke. The main role in etiopathogenesis is played by the left atrial appendage (LAA). As many as 95 % of thrombi in nonvalvular atrial fibrillation are located in the appendage. Prevention of stroke then consists in permanent anticoagulation which, however, has its limits and risks. An alternative method is the left atrial appendage occlusion. In our report, we would like to present a new possibility of the closure using the epicardial system AtriClip (AtriCure)...
