While you will be under the direction of the cardiologists, it is good to be familiar with the views and pre-empt where appropriate (such as turning on biplane) Hafiz to draw this diagram: They will want to visualise the catheter tip. With small movements of your wrist, you can bring the tip of the catheter into view. Biplane can really help at this stage. When they open the arms ready for deployment, they will be looking to check that both arms are lined up equally. Make sure you have both arms in view – you may have to turn your wrist very slightly to keep it in plane. They will go beyond the leaflets first, and then draw back. They rarely accept the first result, so be prepared to repeat this process several times while they perfect clip placement. 3D helps to ensure that the device is approaching the relevant valve segments at the correct angle.
