BACKGROUND AND PURPOSE A noninvasive technique of visualizing the left atrial appendage (LAA) and its thrombus in patients with atrial fibrillation would be of great interest. This study examined the utility of MRI for the assessment of thrombus in the LAA. METHODS We evaluated 50 subjects with nonrheumatic continuous atrial fibrillation and a history of cardioembolic stroke. Each patient rec...
The idea that mechanical intervention to close the left atrial appendage (LAA) might reduce complications from atrial fibrillation (AF) is at least 70 years old. Early attempts to test this idea in humans with surgical ligation were abandoned after only a few years for 2 reasons. First, proponents soon realized that they had no way to choose the candidates believed most likely to benefit withou...
A 46-year-old woman with a 7-year history of profoundly symptomatic daily paroxysmal atrial fibrillation had undergone two percutaneous catheter ablations and multiple medication trials. With informed consent, bilateral pulmonary vein isolation and left atrial appendage occlusion as well as ablation of ganglionated plexi were performed by a totally thoracoscopic technique employing a bipolar ra...
BACKGROUND Safety data on percutaneous left atrial appendage closure arises from centers with considerable expertise in the procedure or from clinical trial, which might not be reproducible in clinical practice. We sought to estimate the frequency and predictors of adverse outcomes and costs of percutaneous left atrial appendage closure procedure in the US. METHODS AND RESULTS The data were o...
Aim of the present study was to investigate far field R-wave sensing (FFRS) timing and characteristics in 34 Myotonic Dystrophy type 1 (DM1) patients undergoing dual chamber pacemaker implantation, comparing Bachmann's bundle (BB) stimulation (16 patients) site with the conventional right atrial appendage (RAA) pacing site (18 patients). All measurements were done during sinus rhythm and in sup...
JOHNSON, J* ALAN, WARD MT* MOORE, AND WILLIAM: E. SEGAR. Small changes in left atrial pressure and plasma antz’diuretic hormone titers in dogs. Am. J. Physiol. 217(l): 210-214. 1969.-Acute studies were conducted on 16 pentobarbital-anesthetized dogs to determine the effect of small increases in left atria1 pressure (LAP) 0x1 plasma ADH levels. The LAP was increased by inflating a balloon insert...
INTRODUCTION Atrial fibrillation (AF) is the most common clinically relevant arrhythmia and it is strongly associated with stroke. Left atrial appendage (LAA) is considered to be the most often source of thrombotic material. In recent decades a number surgical, percutaneous and hybrid approaches for LAA occlusion have been described revealing very different level of success and showing a variet...
Pulmonary vein (PV) ablation is increasingly used to treat highly symptomatic atrial fibrillation. Here, we present a case of infective endocarditis (IE) after PV ablation at the uncommon position of the left atrial appendage entrance. We conclude that iatrogenic intracardial manipulation may create predisposing lesions for IE.
BACKGROUND Randomized trials of left atrial appendage (LAA) closure with the Watchman device have shown varying results, and its cost effectiveness compared with anticoagulation has not been evaluated using all available contemporary trial data. METHODS AND RESULTS We used a Markov decision model to estimate lifetime quality-adjusted survival, costs, and cost effectiveness of LAA closure with...
INTRODUCTION Limited data exist on the outcomes after left atrial appendage closure (LAAC) with the Amplatzer™ Cardiac Plug (ACP; St. Jude Medical, Minneapolis, MN, USA) in patients with atrial fibrillation (AF) with very high stroke and bleeding risks, the subset expected to benefit most from this procedure. The objective of this study was to report clinical outcomes after LAAC with the ACP de...
