Dr. Liviu Klein, a cardiologist at the UCSF Heart and Vascular Center, is Director of the Mechanical Circulatory Support and Heart Failure Device Programs. He specializes in treating patients with heart failure and arrhythmias, including patients before and after heart transplants. He also has expertise in cardiac resynchronization and mechanical therapies such as ventricular assist devices for heart failure. In his research, he 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 at UCSF, he is developing new technologies for monitoring and treating patients with cardiovascular disease (including heart failure), and for those who use ventricular assist devices. At UCSF, Klein is the Director of the Cardiology Clinical Research.

Klein earned a medical degree at the Carol Davila School of Medicine in Bucharest, Romania, and earned a master's of science in clinical investigation at Northwestern University in Evanston, Ill. 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 in Chicago, he completed fellowships in cardiovascular disease, advanced heart failure and transplantation, and clinical cardiac electrophysiology. Klein is a member of the American Heart Association, Heart Failure Society of America, International Society for Mechanical Circulatory Support, and International Society for Lung and Heart Transplant.
