Left Atrial Fractional Shortening: A Simple and Practical “Strain” for Everyone

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 Myxoma: A Rare Tumor in a Child

Atrial myxomas are uncommon in the pediatric population but are very important due to pursuant atrioventricular valve obstruction and systemic embolic events. Concerning multiple symptoms ranging from congestive heart failure to neurological deficits, the diagnosis of this disease is complicated. This paper reports a case of left atrium myxoma in a child treated with a surgical excision o...
