Aortic valve stenosis occurs when the valve located between the heart’s left ventricle and aorta does not fully open. This causes blood to build pressure in the hear and may lead to several health problems. The diagram above does an excellent job utilizing color, explainers, and structure to explain the problem and list potential solutions. First, the pop of red, draws the eye to the Aorta, the main focus of the diagram. Labels in the right column identify essential features of the hearts, yet demonstrates restraint by only providing further explanation when necessary information is required. This allows the diagram to service the viewer, without becoming cluttered. Overall, the structure of the diagram is very strong. The eye is drawn to the aorta, and the natural shape of the artery leads the eyes to the labels in the right column. The diagram is anchored with surgical solution displayed over four columns. This provides an equal distribution of weight throughout the diagram.
