![]() ![]() ![]() reported a similar incidence of LAA thrombus in patients with non-valvular AF. Additionally, a meta-analysis by Mahajan et al. found that in AF patients with intracardiac thrombi, 90% of the thrombi originated in the LAA. ![]() Anticoagulation therapy is recommended for patients with a moderate or high score in order to reduce the risk of thromboembolism.Īnatomically, the left atrial appendage (LAA) is the major source of thrombus formation in patients with AF. To assess the stroke risk, there are two commonly used scoring systems: CHADS 2 (congestive heart failure, hypertension, age >75 years, diabetes 1 point each prior stroke or transient ischemic attack 2 points) and CHA 2DS 2-VASC (congestive heart failure, hypertension, age >65=1 point, > 75=2 points, diabetes mellitus, prior strokes 2 points, vascular disease, female gender 1 point each). The overall proportion of strokes thought to be due to AF was reported as 14.7%, a number that steadily increases with age from 6.7% (ages 50 to 59 years) to 36.2% (ages 80 to 89 years). The United States alone is estimated to have a prevalence of 7 million patients with new or recurrent stroke. The national incremental cost associated with sequelae of AF is estimated to range from $6 to $26 billion per year. The most serious complication, cardioembolic strokes, carries a high mortality risk.AF is estimated to contribute to more than 80,000 deaths annually according to the American Heart Association Statistics Committee 2009 update. Hospitalizations associated with AF as the primary diagnosis exceed 460,000 each year. Prevalence of AF increases with age, affecting approximately 9.0% of the population 80 years or older. It has been estimated that 2.3 million people in the United States have clinically recognized AF, with the number expected to increase to approximately 5.6 million by 2050. The preclinical studies and clinical trials, as well as the next generation of the device.Ītrial fibrillation (AF) is one of the most common arrhythmias seen in clinical cardiology practice. Nearly 6,000 patient-years of follow-up, the WATCHMAN LAAC Device is approved by FDA. On the robust WATCHMAN clinical program which consists of numerous studies, with more than 2,400 patients and High-risk patients with non-valvular atrial fibrillation who are seeking an alternative to long-term warfarin therapy. It offers a new stroke risk reduction option for The WATCHMAN device (Boston Scientific, MA) is a percutaneous left atrial appendage closureĭevice which has been tested prospectively in multiple randomized trials. The left atrial appendage is the major source of thrombus formation in patients Stroke risk in these patients are needed. Therefore, alternative means of treatment to reduce increased risk of bleeding), especially for aging patients. In AF patients is well established, its use is difficult due to narrow therapeutic windows and additional complications Although the potential of warfarin to reduce systemic embolization ![]() Cardioembolic strokes carry a high mortality risk. With non-valvular AF have an approximately 5-fold increase in the risk of stroke, with an exponential increase with advancingĪge. Atrial fibrillation (AF) is one of the most common arrhythmias seen in clinical cardiology practice. ![]()
