Left atrial appendage myxoma masquerading as left atrial appendage thrombus

Asian Cardiovascular and Thoracic Annals, 2013
Myxomas are the most common benign tumors of the heart. They can arise from any heart chamber, but have rarely been described as originating from the left atrial appendage. We describe a case of left atrial appendage myxoma mimicking a left atrial appendage thrombus, and presenting with microembolization to the coronaries.

Left atrial appendage occlusion [PDF]

Heart, 2014
Left atrial appendage (LAA) occlusion for stroke and thromboembolism prevention in patients with atrial fibrillation (AF) represents a significant advancement in the field of cardiovascular disease. Prevention and avoidance of the devastating consequences of thromboembolic complications from AF continues to be central in the management of these ...

Left Atrial Appendage Closure after Ablation for Atrial Fibrillation.

New England Journal of Medicine
BACKGROUND Oral anticoagulation is recommended after ablation for atrial fibrillation among patients at high risk for stroke. Left atrial appendage closure is a mechanical alternative to anticoagulation, but data regarding its use after atrial ...

Left atrial appendage morphology predicts the formation of left atrial appendage thrombus

Cardiovascular Electrophysiology, 2021
Nonchicken wing left atrial appendage (LAA) morphology is associated with higher risk for stroke in patients with atrial fibrillation (AF) than chicken wing (CW) morphology.

Left Atrial Appendage Closure

Current Cardiology Reports, 2010
Stroke prevention is the primary goal in atrial fibrillation (AF) given its clinical and socioeconomic impact. With AF, the prevalence of thromboembolic stroke continues to rise and there is an urgent need to develop better strategies of stroke prevention.

Band Occlusion of the Atrial Appendage

Journal of Cardiac Surgery, 2010
A new device has been developed for occlusion of the left atrial appendage (LAA). Previous investigations have been in the canine model. The canine atrial appendage does not vary in size and shape as much as the human. The goal of this study was to investigate band occlusion of right atrial appendages in the pig model, which are more broad based.The ...

Inverted left atrial appendage

The Japanese Journal of Thoracic and Cardiovascular Surgery, 2000
An unexpected left atrial mass was found during postoperative echocardiography in a 17-years old man following aortic valve replacement, suggesting thrombus, vegetation and neoplasm. Reoperation showed that the mass to be an inverted left atrial appendage. Left ventricular venting may cause such inversion.

Efficacy and safety of left atrial appendage electrical isolation during catheter ablation of atrial fibrillation: an updated meta-analysis.

Europace, 2020
AIMS Left atrial appendage electrical isolation (LAAEI) has been shown to improve freedom from all-atrial arrhythmia recurrence in patients with non-paroxysmal atrial fibrillation (AF).
