Dr. Liviu Klein, a cardiologist at the UCSF Heart & Vascular Center, is director of Advanced Heart Failure Comprehensive Care Center and director of the Mechanical Circulatory Support Program. He specializes in caring for patients with heart failure and arrhythmias, including care before and after surgery for those receiving heart transplants. He also has expertise in cardiac resynchronization and mechanical therapies, such as ventricular assist devices for heart failure.

In his research, Klein studies the epidemiology of heart failure in women, including those at risk for sudden cardiac death. Together with colleagues in the Department of Bioengineering and Therapeutic Sciences, he is developing new technologies for monitoring and treating patients with heart failure and other kinds of cardiovascular disease, including those who use ventricular assist devices.

Klein earned a medical degree at the Carol Davila University of Medicine in Bucharest, Romania. He earned a master's of science degree in clinical investigation at Northwestern University. He completed a residency in internal medicine at the Advocate Illinois Masonic Medical Center in Chicago and a fellowship in cardiovascular epidemiology at Northwestern University's Feinberg School of Medicine. At Northwestern's McGaw Medical Center, he completed fellowships in cardiovascular disease, advanced heart failure and heart transplantation, and in clinical cardiac electrophysiology.

Klein is a member of the American Heart Association, Heart Failure Society of America and International Society for Lung and Heart Transplantation. He has published more than 100 peer-reviewed articles and books.

"You have to be like a detective and figure out which condition led to heart failure."

The future of cardiac care relies on ongoing connectivity with patients to delay disease progression and improve quality of life.
