27 Major Challenges 1.Accurate contemporary risk-adjusted depictions of survival after cardiac transplantation 2.Risk-adjusted contemporary survival after mechanical circulatory support 3.Effective analyses that unveil the shortcomings of MCS therapy How can INTERMACS help shape the Future of MCS? INTERMACS Annual Meeting March 2012

28 Major Challenges 4. Find “common ground” between Cardiac Transplantation and MCS analyses that accommodate the differing patient populations in Cardiac Transplantation, Destination Therapy – Transplant Ineligible, and Destination Therapy – Transplant Alternative How can INTERMACS help shape the Future of MCS? INTERMACS Annual Meeting March 2012

29 Major Challenges 5. Develop analyses that are sensitive to the evolution of individual devices and device categories as we allocate device therapies. How can INTERMACS help shape the Future of MCS? INTERMACS Annual Meeting March 2012

30 Specific Adverse Events that challenge the long-term implementation of MCS: Early mortality and its causes Infection of driveline and pump pockets Right Ventricular Failure Pump and Outflow Graft Thrombosis Renal Dysfunction Plus Quality of Life and Functional Capacity How can INTERMACS help shape the Future of MCS? INTERMACS Annual Meeting March 2012

31 Coordinator Training Session, March 11, Device Malfunction Device malfunction denotes a failure of one or more of the components of the MCSD system which either directly causes or could potentially induce a state of inadequate circulatory support (low cardiac output state) or death. The manufacturer must confirm device failure. A failure that was iatrogenic or recipient-induced will be classified as an Iatrogenic/Recipient-Induced Failure. Device failure should be classified according to which components fails as follows: 1)Pump failure (blood contacting components of pump and any motor or other pump actuating mechanism that is housed with the blood contacting components). In the special situation of pump thrombosis, thrombus is documented to be present within the device or its conduits that result in or could potentially induce circulatory failure. 2) Non-pump failure (e.g., external pneumatic drive unit, electric power supply unit, batteries, controller, interconnect cable, compliance chamber) The Adverse Event: Device Malfunction Form is to be collected at time of event. FDA has set forth regulations regarding these events. For the purposes of submitting adverse event device malfunction information to the FDA, you must enter any device malfunction event that occurs within 72 hours of the event.

34 Coordinator Training Session, March 11, Major Infection A clinical infection accompanied by pain, fever, drainage and/or leukocytosis that is treated by anti-microbial agents (non- prophylactic). A positive culture from the infected site or organ should be present unless strong clinical evidence indicates the need for treatment despite negative cultures. The general categories of infection are listed below: Localized Non-Device Infection Infection localized to any organ system or region (e.g. mediastinitis) without evidence of systemic involvement (See sepsis definition), ascertained by standard clinical methods and either associated with evidence of bacterial, viral, fungal or protozoal infection, and/or requiring empirical treatment. Percutaneous Site and/or Pocket Infection A positive culture from the skin and/or tissue surrounding the drive line or from the tissue surrounding the external housing of a pump implanted within the body, coupled with the need to treat with antimicrobial therapy when there is clinical evidence of infection such as pain, fever, drainage, or leukocytosis. Internal Pump Component, Inflow or Outflow Tract Infection Infection of blood-contacting surfaces of the LVAD documented by positive site culture. (There should be a separate data field for paracorporeal pump that describes infection at the percutaneous cannula site, e.g. Thoratec PVAD). Sepsis Evidence of systemic involvement by infection, manifested by positive blood cultures and/or hypotension. INTERMACS Protocol Mar 5, 2012 INTERMACS Annual Meeting March 2012

38 Coordinator Training Session, March 11, Neurological Dysfunction Any new, temporary or permanent, focal or global neurological deficit ascertained by a standard neurological examination (administered by a neurologist or other qualified physician and documented with appropriate diagnostic tests and consultation note). The examining physician will distinguish between a transient ischemic attack (TIA), which is fully reversible within 24 hours (and without evidence of infarction), and a stroke, which lasts longer than 24 hours (or less than 24 hours if there is evidence of infarction). The NIH Stroke Scale (for patients > 5 years old) must be re-administered at 30 and 60 days following the event to document the presence and severity of neurological deficits. Each neurological event must be subcategorized as: 1)Transient Ischemic Attack (acute event that resolves completely within 24 hours with no evidence of infarction) 2)Ischemic or Hemorrhagic Cardiovascular Accident/CVA (event that persists beyond 24 hours or less than 24 hours associated with infarction on an imaging study.)

After 7 days post implant  Any transfusion of packed red blood cells (PRBC) after 7 days following implant with the investigator recording the number of units given.
