 Mark Ratcliffe, M.D. Professor and Vice-Chair, UCSF Department of Surgery 4150 Clement Street Dr. Ratcliffe received his B.A. in physics from Denison University and received his M.D. from Case Western Reserve University. Following his intern and residency in general surgery at Johns Hopkins Hospital, Dr. Ratcliffe became a Culpepper Fellow at the U. Penn Harrison Department of Surgical Research. In 1987 Dr. Ratcliffe became Chief Resident of general surgery at the Hospital of the University of Pennsylvania and in the following years became a Fellow of Cardiothoracic surgery there. Presently Dr. Ratcliffe is the Chief of Surgery and Cardiothoracic Surgery at the SFVA, is the Cardiac Biomechanics lab director and is a Professor in Residence at UCSF. |

She has a special interest in the endovascular treatment of thoracic aortic diseases, including descending thoracic aortic aneurysms, acute and chronic type B aortic dissection. She also has a special interest in aortic valve surgery, ascending aortic and arch surgery, mitral valve repair, reoperative cardiac surgery, off-pump coronary artery bypass, and Maze procedure for atrial fibrillation. |
 Art Wallace, M.D. PhD Staff Physician, Anesthesiology
Service, SFVAMC SFVAMC Phone: 415-750-2069 Email: wallacea@anesthesia.ucsf.edu Arthur Wallace has spent the last thirty years focused on prevention and treatment of cardiovascular disease. His initial work began with methods to use CT scans to image coronary anatomy and ventricular function. He then studied autonomic control of the vasculature. At UCSF he has continued to focus on cardiovascular research. The primary research focus is in the prevention of perioperative myocardial infarctions conducting numerous clinical trials of anti-ischemic agents. Dr. Wallace was a co-investigator on the initial perioperative beta blocker study which demonstrated a reduction in long term mortality. He then was PI of a clinical study of the alpha-2 agonist clonidine and demonstrated a reduction in both 30-day and 2-years perioperative mortality. Since the completion of these clinical studies the American Heart Association and American College of Cardiology have made perioperative beta blockade a level-1 standard of care. Dr. Wallace then set up a program to assist hospitals and hospital systems implement perioperative beta blocker programs designed to reduce perioperative morbidity and mortality. Dr. Wallace has conducted four large scale epidemiologic studies of perioperative risk identifying a number of practice patterns that increased morbidity and mortality. Dr. Wallace has a long standing research collaboration with Dr. Mark Ratcliffe, a cardiac surgeon and the chief of surgery at the VA San Francisco, and has been an investigator on Dr. Ratcliffe's NIH grants for the last 15 years.
