Your cardiologist's office will schedule your vascular ultrasound, echocardiogram or venous ablation at the Prairie Diagnostic Center at HSHS St. John's Hospital (PDC). Someone from St. John's pre-registration department will call to register you before your scheduled procedure date. 

You may return to normal activity after leaving PDC. Within 72 hours of your testing your cardiologist will discuss the results of your procedure and provide a treatment plan for you.

If you must cancel your appointment, please notify your doctor's office at least 24 hours in advance.
