Inverted left atrial appendage masquerading as a left atrial mass

Inverted Left Atrial Appendage Masquerading as a Left Atrial Mass

An inverted left atrial appendage after cardiac surgery is a rare finding and can be misinterpreted as a thrombus, mass, or vegetation. We report a case where intraoperative transesophageal echocardiography assisted in making an accurate diagnosis.

Inverted 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 ...

A 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...

left atrial and left atrial appendage mass diagnosed by cardiac imaging: a case report

introduction left atrial thrombi are present in one third of patients with severe rheumatic mitral stenosis and atrial fibrillation. a left atrial mass can be diagnosed as a thrombus by transthoracic echocardiography in the presence of the predisposing factors for a thrombus such as mitral stenosis and atrial fibrillation. the sensitivity of transthoracic echocardiography for detecting left atr...
