What is it indicated for?
ATLAAS is indicated for the exclusion of the heart's Left Atrial Appendage, performed under direct visualization, in conjunction with other cardiac surgical procedures. Direct visualization, in this context, requires that the surgeon is able to see the heart directly, with or without assistance from a camera, endoscope, etc., or other appropriate viewing technologies.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
