This is a type of ultrasound scan which helps the team to make careful measurements of the heart valve. A small probe is moved around the chest and sends out sound waves that create echoes when they bounce off different parts of the body. These echoes are picked up by the probe and turned into a moving image on a monitor while the scan is carried out.
Some gel will be applied to your chest or directly to the ultrasound probe. You’ll be asked to lie on your left side and the probe will be moved across your chest.
The test takes 15 to 30 minutes and is usually carried out at a hospital or clinic by a cardiologist or a trained specialist called a cardiac physiologist.
