New patient guidelines for heart devices

Cardiac specialists will use new guidelines to determine who should receive a mechanical heart-pumping device. The guidelines have the potential to change clinical practice patterns for patients with severe heart failure. Dr. Morgan's presentation at the ISHLT annual meeting in San Diego highlights the importance of these changes.
