260 left atrial appendage (LAA) or right atrial appendage (RAA) biopsies were collected from 227 patients. Sixty‐six samples were not cryosectioned because of low tissue quantity. Nineteen samples were excluded due to poor tissue quality observed during microscopy. An additional 4 samples were excluded as a result of failure to pass built‐in quality control (QC) during analysis with JavaCyte. Reasons for exclusion were poor myocyte detection or poor thresholding of images.
