Atrial fibrillation (AF) is leading cardiac arrhythmia with important clinical implications. Its diagnosis is usually made on the basis on 12-lead ECG or 24-hour Holter monitoring. More and more clinical evidence supports diagnostic use of cardiac event recorders and cardiovascular implantable electronic devices (CIED). Treatment options in patients with atrial fibrillation are extensive and are based on chosen rhythm and/or rate control strategy. The use and selected contraindications to AF related pharmacotherapy, including anticoagulants are shown...

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.

OBJECTIVES: We describe the use of trans-thoracic and trans-conduit puncture to access the atria and perform interventional procedures in patients who have undergone conduit total cavopulmonary anastomosis. BACKGROUND: Catheter access to the atria following intra or extra-cardiac Fontan is desirable when there is a need for trans-atrial interventions. METHODS: Between 2009 and 2014, 5 patients ages 7 to 28 years underwent this approach; three trans-thoracic and 2 trans-conduit punctures...

A 7-year-old female child presented with pyrexia of unknown origin. She had received an empirical regimen of antibiotic for possible endocarditis. Evaluation included multiple imaging supports and blood culture. She had left main coronary artery to right atrium coronary cameral fistula, restricted patent ductus arteriosus, vegetation at the right atrial exit of fistula and negative blood culture. Ongoing fever more than 2 weeks, oscillating vegetation in the echo and histopathological evidence of healing vegetation suggested definite diagnosis of infective endocarditis...

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...

Percutaneous left atrial appendage closure is an alternative treatment for stroke and systemic thromboembolism risk reduction in non-valvular atrial fibrillation (AF). However, the neurohormonal impact of epicardial exclusion of the left atrial appendage (LAA) with the LARIAT procedure is unknown. Evaluation of changes in atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) levels in AF patients underwent percutaneous LAA suture ligation. Sixty six patients underwent successfully percutaneous LAA suture ligation using LARIAT device...

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)...

REVIEW
Michael C Giudici, Prashant D Bhave
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...

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...

BACKGROUND: Amplatzer occluder and Cardio-O-fix occluder are currently used in percutaneous closure of patent foramen ovale. However, there is still a lack of relevant reports comparison the differences between them. The aim of this study was to evaluate the short-term and mid-term safety and efficacy of the Cardi-O-fix occluder in preventing recurrent cerebrovascular events in patients with a patent foramen ovale (PFO). METHODS: We enrolled 246 patients (105 men) with a PFO from May 30, 2013 to March 30, 2015 in this single-center prospective study...

A 43-year-old man who had had a history of atrial septal defect (ASD) device closure 31 months previously presented with abrupt chest and back pain along with progressive cardiogenic shock and cardiac arrest. After resuscitation, he was diagnosed with cardiac tamponade. Diagnostic and therapeutic surgical exploration revealed left atrium (LA) perforation due to LA roof erosion from a deficient aortic rim. Device removal, primary repair of the LA perforation site, and ASD patch closure were performed successfully...

BACKGROUND AND OBJECTIVES: Assessment of left ventricle (LV) function by using strain and strain rate is popular in the clinical setting. However, the use of these echocardiographic tools in assessing right ventricle (RV) failure, and the manner in which they both reflect the functional capacity of the patient, remains poorly understood. This study aimed to investigate the change in exercise capacity and strain between before and (1 month) after the transcatheter closure of atrial septal defects (ASDs)...

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...

Atrial septal defects can be closed surgically or percutaneously. However, percutaneous closure of atrial septal defects carries some risks. Embolization of the atrial septal occluder is the major adverse event. Embolization of the device into the main pulmonary artery, left atrium, right ventricle, aortic arch, descending aorta, abdominal aorta, iliac bifurcation, and iliac arteries can be seen. We report the case of a 19-year-old man with migration of an Amplatzer (St Jude Medical, St Paul, MN) atrial septal occluder into the iliac bifurcation with the development of abdominal aortic dissection 1 month after successful percutaneous closure...
