Left atrial mass. Thrombus mimicking myxoma.
A 31-year-old woman underwent elective transthoracic echocardiography for paroxysmal atrial fibrillation, which showed a large left atrial mass. A two-dimensional echocardiogram showed a large left atrium mass. Subsequent transesophageal echocardiography showed a 3 cm x 3 cm circular mass with smooth contours. The differential diagnosis included myxoma versus thrombus, but because of morphology...

a 51-year-old man was admitted to the emergency department with palpitation and atypical chest pain. he had a history of percutaneous mitral valve commissurotomy 20 years previously. he did not use any drugs. physical examination was unremarkable except for a loud s1 on auscultation. the surface electrocardiogram (ecg) showed atrial fibrillation rhythmwith rapid ventricular response and right b...
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 کاملComplex left atrial appendage morphology and left atrial appendage thrombus formation in patients with atrial fibrillation.
BACKGROUND In patients with atrial fibrillation (AF), most thrombus forms in the left atrial appendage (LAA). However, the relation of LAA morphology with LAA thrombus is unknown. METHODS AND RESULTS We prospectively enrolled 633 consecutive patients who were candidates for catheter ablation for symptomatic drug-resistant AF. Transesophageal echocardiography (TEE) was performed to assess LAA ...
متن کاملInverted left atrial appendage masquerading as myxoma.
A39-year-old woman was evaluated for an intra-atrial mass after having suffered a CT-verified stroke. She experienced a total remission of her neurological symptoms within 6 weeks. A search for embolic foci was conducted. Transthoracic echocardiography revealed a mass in the left atrium. MRI confirmed the diagnosis. At surgery, instead of the suspected myxoma, an inverted left atrial appendage ...
