Meet Our Team
Washington Hospital Healthcare System first began offering open heart surgery
(coronary artery bypass surgery) to our community more than 30 years ago.
Today, we continue to provide world-class cardiac care and with our affiliation
with UCSF Health, we can provide academic-level care with the convenience
of local treatment. UCSF is ranked as one of the best hospitals in the
nation for Cardiology and Heart Surgery, according to
U.S. News & World Report. “Our collaboration gives the community direct access to a level
of specialized cardiac care rivaling the most advanced academic centers
in the country,” says cardiac surgeon Ramin E. Beygui, MD, Washington
Hospital’s medical director of Cardiac Surgery and a faculty member
at UCSF Medical Center.
