Arizona Heart Institute

Arizona Heart Institute (AHI) is a world-renowned center for the treatment of cardiovascular disease, established in 1971 by Dr. Edward Diethrich. Based in Phoenix, Arizona, the institute is recognized for pioneering numerous 'firsts' in cardiac care, including advanced minimally invasive endovascular procedures and the first freestanding outpatient clinic dedicated to heart health. AHI provides a comprehensive range of services including diagnostic imaging, interventional cardiology, and complex vascular surgery. Now a part of the Abrazo Health network under Tenet Healthcare, the institute continues to integrate clinical excellence with medical research and education, serving as a major referral center for complex cardiovascular cases globally.
