Heart and coronary artery evaluation. Coloured 3D computed tomography (CT) angiography scan of the heart (left) and coronary arteries (right) of a 49-year-old man. The scan is done to evaluate the state of the coronary arteries. Blockages of these arteries cause heart attacks. This is an anterior view. In the foreground is the right coronary artery (far right). At far right is the left coronary artery and its major branch the left anterior interventricular artery (also called the left anterior descending artery). For this heart from a left anterior oblique view, see image C037/1799.
