When people have aortic stenosis, the aortic valve does not open fully. This prevents blood from flowing normally from the left ventricle, through the aortic valve, and to the aorta. The direction of blood flow is shown by the black arrow. The aorta is a big blood vessel that carries blood to the rest of the body.

View OriginalTransthoracic echocardiogram (echo)
This picture shows a person getting an echocardiogram (or "echo"). To do an echo, a doctor or nurse puts some gel on a persons chest. He or she presses a thick wand (called a "transducer") against the chest and moves it around. An echo uses sound waves to create images of the heart that appear on a computer screen. A test called an ECG is done during an echo. For an ECG, patches (called "electrodes") are stuck to a person's chest. Wires run from the patches to a machine that records the electrical activity of the heart.

View OriginalPerson having an ECG
This drawing shows a man having an ECG (also called an electrocardiogram or EKG). He has patches, called "electrodes," stuck onto his chest, arms, and legs. Wires run from the electrodes to the ECG machine. An ECG measures the electrical activity in the heart.
