**Abstract**

This chapter describes the use of ECMO for interventional cardiology procedures. In recent years, the rapid development of these techniques has allowed treatment of extremely complex patients, not subject to traditional cardiac surgery due to the very high operational risk which was, therefore, intended only for palliative medical therapy. These procedures are carried out by a multidisciplinary team composed of an interventional cardiologist, heart surgeon, anaesthetist, and perfusionist who collaborate closely during all phases of the patient's hospitalisation.
