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...

A Huge Congenital Left Atrial Appendage Aneurysm

A 33‐year‐old female patient presented to us with intermittent chest discomfort for 2 years and sudden syncope 1 month before without coronary heart disease, hypertension, or valvular heart disease. She was diagnosed as pericardial cyst by a physician of local hospital with transthoracic echocardiography (TTE), and her thoracoscopic resection was discontinued when the surgeon observed the left ...

Left atrial appendage aneurysm and atrial septal defect.

We present a case of left atrial appendage (LAA) aneurysm and atrial septal defect in a 1-year-old child without cardiovascular symptoms referred for cardiac murmurs and cardiomegaly and diagnosed by 2and 3-dimensional transthoracic echocardiography. Subcostal and apical views showed a wide, fenestrated ostium secundum-type atrial septal defect with redundant septum (Fig. 1, arrow). The right-s...
