Neo-Left Atrium Construction on the Beating Heart After Extirpation of a Huge Mediastinal Tumor Invading Heart and Lung Miralem Pasic, MD, PhD, Evgenij Potapov, MD, PhD The Annals of Thoracic Surgery Volume 100, Issue 6, Pages 2350-2352 (December 2015) DOI: 10.1016/j.athoracsur.2015.02.109 Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions
Fig 1 Preoperative computed tomography of the chest demonstrates mediastinal tumor (yellow asterisk) invading lung and heart and “wrapping” descending aorta. Tumor has broken into left atrium (LA), affecting mitral annulus. A separate 4 × 6 cm tumor (red asterisk) fills left ventricle (LV). Red arrow shows previously implanted bileaflet mechanical mitral valve prosthesis. (Ao = descending aorta; RA = right atrium; RV = right ventricle.)

Fig 2 (A–C) Postoperative computed tomography of the chest shows the neo–left atrium (nLA) (yellow bracket in A; nLA in B; yellow arrow in C) constructed from 2 bovine pericardial patches after tumor removal in toto and implantation of new mitral bioprosthesis (blue arrow in B). (Ao = ascending aorta; AoD = descending aorta; LV = left ventricle; PA = pulmonary artery; PV = pulmonary veins; RA = right atrium; RV = right ventricle.)
