Fig 2 Macroscopic findings of left atrial ablation. (CS = coronary sinus; EnC = endocardium; EpC = epicardium.) The Annals of Thoracic Surgery 2012 93, 2053-2056DOI: (10.1016/j.athoracsur.2011.11.065) Copyright © 2012 The Society of Thoracic Surgeons Terms and Conditions
Fig 3 Histologic study of a transmural cross-section collected from the atrial wall. Damage to cardiomyocytes is evident over full thickness of the transmural sample (hematoxylin and eosin, ×40 [A]; Masson trichrome, ×40 [B]).
