Cardio Vascular Services, formerly Echo Services was established initially to provide specialist diagnostic services in echoc ... ardiography - a non-invasive approach to diagnose heart problems, that uses sound waves to look at the structure and function of the heart. Echo Services became CVS - Cardio Vascular Services to better reflect the services we now are offering to patients. Cardiologists and Vascular/Endovascular surgeons work together at CVS to care for patient's cardiac and vascular health. CVS now has sites across Western Australia and Victoria.
