Equipoise Does Not Exist for REVIVE IT Andrew Boyle, MD Heart and Vascular Center Director, Florida Chairman of Cardiology Medical Director of Heart Failure, Cardiac Transplantation, and Mechanical Circulatory Support Cleveland Clinic Florida Weston, FL
Put Another Way: Is this the right time, with the right device, with the right adverse event profile to move forward with REVIVE IT in a less ill population of patients?
Relevant Financial Relationship Disclosure Statement Equipoise with REVIVE IT Andrew Boyle, MD I will not discuss off label use and/or investigational use of drugs/devices The following relevant financial relationships exist related to my role in this session: Thoratec: Medical Advisory Board and Honoraria

And How Representative are These Patients Anyways? • Anticipating 2500 screening failures in the registry to find 100 eligible patients for the study • How meaningful is that to my clinical practice?
Who Are the Patients Who Would Consent to Such a Study? • Have to agree to be randomized to a VAD • Therefore will be a selected population of patients who are already interested in a VAD • Being randomized to OMM arm is not a benign event for these patients: remember patients assigned to the XVE arm of the HM II DT trial?
Conclusions • We should be moving to a less sick population which is the ambulatory Class IV patient • Data will be needed to convince MD’s to refer for MCS in IM 4 and 5 patients let alone IM 6 and 7 • The devices currently commercially available do not have a favorable adverse event profile that would justify moving to a Class III population • We will not get a DO OVER. If this is done poorly MCS will forever be banished to the inotrope dependent patient. We better do it right the first time.
