Should I have IV antibiotics prior to colonoscopy?

I am scheduled for a colonoscopy. One cardiologist says yes to antibiotic treatment IV style (which requires my being there two hours ahead of procedure so I can have required meds) while another doctor says new protocol says meds are not required. Had biologic aortic valve surgery in 2004 and heart ablation in 2008. Which is the course to be followed in this case? I am postponing colonoscopy until I can be certain, since using IV antibiotics after all the colon cleansing agents will be hard on the body.

Michael J. Mihalick, MDThe current guidelines recommend no antibiotic prophylaxis prior to GI endoscopy because the risk is so low. Previous recommendations were based on theoretical estimates that have not been confirmed.
