title: Chronic total occlusion of the left main coronary artery with normal left ventricular motion: the occluded site confirmed by three-dimensional computed tomography.
abstract: Total occlusion of the left main trunk (LMT) frequently results in sudden cardiac death. As a result, it is rarely observed on coronary arteriogram. There are only a few reports on chronic total occlusion of the LMT. Most patients present with recent, severe angina, but it is not easy to distinguish chronic total occlusion of the LMT from other types of severe coronary heart diseases. Here, we report a very rare case of chronic total occlusion of the LMT. The patient is a 38-year-old female with a history of three normal deliveries. Chronic total occlusion of the LMT was suspected on coronary arteriogram 2 years previously in the other hospital; however, she continued working as a part-time employee at a supermarket. She was referred to our hospital because of slightly increased effort angina and shortness of breath. The final diagnosis and the site of occlusion were determined by three-dimensional computed tomography (3-D CT). The patient underwent coronary artery bypass graft (CABG) surgery, and ischemic symptoms completely disappeared.
