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...
