1 Extrinsic Compression of the Left Main Coronary Artery by Atrial Septal Defect 
Yusuke Jo, MD, Akio Kawamura, MD, Masahiro Jinzaki, MD, Takashi Kohno, MD, Toshihisa Anzai, MD, Shiro Iwanaga, MD, Kiyokazu Kokaji, MD, Tsutomu Yoshikawa, MD, Ryohei Yozu, MD, Sachio Kuribayashi, MD, Satoshi Ogawa, MD  The Annals of Thoracic Surgery  Volume 86, Issue 6, Pages (December 2008) DOI: /j.athoracsur Copyright © 2008 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Coronary angiographic scan revealed a 75% long, smooth stenosis of the left main coronary artery ostium without other evidence of coronary artery disease. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2008 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 (A) The extrinsic compression of the proximal left main coronary artery (LMCA) by the marked dilatation of main pulmonary artery (47 mm in diameter) was shown in a cardiac 64-slice multi-detector computed tomographic scan on admission. Any atherosclerotic plaque was absent inside LMCA. (B) The narrowing of LMCA disappeared 4 months after the operation. The pulmonary trunk diameter decreased to 38 mm.
