Isolated left atrial appendage ostial stenosis.
A patient with atrial tachycardia presented with dyspnoea on exertion. Transoesophageal echocardiography revealed idiopathic left atrial appendage stenosis. The mouth of the atrial appendage was narrowed, and there was a high velocity to and fro jet between the left atrial body and the left atrial appendage. The study, therefore, suggested isolated left atrial appendage orifice stenosis.
متن کاملA Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
متن کاملLeft atrial appendage ostial stenosis associated with rheumatic mitral stenosis \
Isolated left atrial appendage (LAA) stenosis is a very rare entity that is almost always detected coincidentally with transesophageal echocardiography (TEE). The clinical consequences of this condition are still unknown, but thrombus formation is likely to occur in the narrowed area. A 51-year-old female was admitted to an outpatient clinic due to the complaint of dizziness. Physical examinati...
متن کاملA deadly mix - rheumatic mitral stenosis, preexcited atrial fibrillation, left atrial appendage thrombus and left atrial appendage accessory pathway
A 38-year-old female with rheumatic mitral stenosis on medical management presented with palpitations and presyncope since 10 days. Electrocardiogram showed an irregular rhythm at a rate of 160 bpm with preexcitation suggestive of atrial fibrillation with a left free wall accessory pathway (Fig. 1). Transthoracic echocardiography showed severe rheumatic mitral stenosis with a valve area of 1 cm...
متن کاملLeft Atrial Appendage Remodeling After Lariat Left Atrial Appendage Ligation.
BACKGROUND Left atrial appendage (LAA) ligation with the Lariat device is being used for stroke prevention in atrial fibrillation. Residual leaks into the LAA are commonly reported after the procedure. Little is known about the anatomic LAA remodeling after Lariat ligation. METHODS AND RESULTS In an exploratory study, we evaluated LAA 3-dimensional geometry via computed tomographic scan in 31...
