1. An example of balanced triple-vessel disease
An example of balanced triple-vessel disease. Shown is a 42-year-old man with no history of ischemic heart disease for whom the perfusion images show no perfusion defects at stress or rest. However, the left ventricle was dilated at stress compared with rest, so-called transient ischemic dilatation. Also, the ejection fraction (EF) decreased after the exercise test compared to rest because of postischemic stunning. These are signs of severe ischemia, and therefore, the test is not normal despite the lack of perfusion defects. Because of global ischemia, the perfusion is decreased homogenously, and no area of normal perfusion and thus no perfusion defects exist. The patient showed triple-vessel disease at coronary angiography and was treated with percutaneous coronary intervention. ANT, anterior; INF, inferior; SEPT, septal.
