Stroke is the most feared complication of atrial fibrillation. To prevent stroke, left atrial appendage exclusion has been targeted, as it is the prevalent site for formation of heart thrombi during atrial fibrillation. We review the historic development of methods for exclusion of the left atrial appendage and the evidence to support its amputation during routine cardiac surgery.

The left atrial appendage (LAA) in the setting of non-valvular atrial fibrillation (NVAF) is the predominant location for intracardiac thrombus formation. An absent LAA is a very rare congenital cardi...
Atrial fibrillation (AF) triggers within the coronary sinus (CS)/great cardiac vein (GCV) and the left atrial appendage (LAA) have been recognized as non-pulmonary veins (PV) triggers of AF.
What is the most likely diagnosis?Mitral stenosis.Pericardial cyst.Left atrial appendage aneurysm.Left atrial myxoma.Atrial septal defect.
Patients with atrial fibrillation (AF) undergoing cardiac surgery are at substantially increased risk for stroke. Increasing evidence has suggested that surgical left atrial appendage occlusion (S-LAA...
The purpose of this study was to determine whether surgical left atrial appendage (LAA) exclusion performed during mitral valve surgery is associated with a reduction in cerebrovascular events in pati...
Surgical amputation of the left atrial appendage (LAA) is an established intervention during surgical atrial fibrillation (AF) therapy. However, its effects on the endocrine function of th...
The purpose of the study is to collect data regarding ligation of the left atrial appendage at least 12 months after surgery for patients that had exclusion of the left atrial appendage as...
After obtaining a consent, bed side cardiac ultrasonography will be performed for cases undergoing transesophageal echocardiography to evaluate the correlation between left atrium volume a...
Stroke is a major cause of morbidity in western society, and an infrequent complication of cardiac surgery. The majority of thromboembolic strokes arise from the left atrium, in particular...
The proposed work seeks to further understand the effects of LAA occlusion on cardiac structure and function, and in homeostasis. Numerous studies have implicated the left atrial appendag...

The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).
Loss of a limb or other bodily appendage by accidental injury.
The removal of a limb or other appendage or outgrowth of the body. (Dorland, 28th ed)
Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann's bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
