Edward "Ted" B. Diethrich, MD (August 6, 1935 - February 23, 2017) was an American cardiovascular surgeon, author, and innovator.
He was known for his innovations in the field of vascular surgery as well as for founding the Arizona Heart Hospital in Phoenix, Arizona. [1]
Diethrich was born in Hillsdale, Michigan in 1935. He obtained his undergraduate (1956) and medical (1960) degrees from the University of Michigan. [2] He then completed his surgical residency at St. Joseph's Mercy Hospital in Ann Arbor, Michigan, and the Henry Ford Hospital in Detroit. He received his thoracic and cardiovascular surgery training at the Baylor College of Medicine in Houston, Texas, where he later worked with surgeon Michael DeBakey in the development of human heart transplantation. [3]
After moving to Arizona, Diethrich founded the Arizona Heart Institute in 1971, the nation's first freestanding clinic solely devoted to cardiac and vascular diseases. This expanded into the nation's first outpatient cardiac catheterization laboratory in 1979 and the world's first school of cardiac ultrasound in 1982. [4]
Diethrich later founded the Arizona Heart Hospital in 1998 and served as its medical director and Chief of Cardiovascular and Endovascular Surgery from 1998 to 2010. In 1996 Diethrich performed the first endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysm. In 1997 he co-founded, ENDOLOGIX based on the stent graft research and patents of Myles Douglas, MD a Cardiovascular Surgeon working on the AHI staff. Another first was the stent graft treatment of a Thoracic Aortic Dissection in 1997. Over the course of his career, he co-authored nearly 400 papers and trained over a thousand surgeons and other specialists in cardiovascular surgery and endovascular techniques, including several leaders in the fields of vascular and cardiac surgery, including Venkatesh Ramaiah, who succeeded him in 2010 as medical director of Abrazo Arizona Heart. [5] [3]
Diethrich achieved national recognition for performing surgery on live television, [6] including on then-Senator Barry Goldwater in 1982. [7] Later, after he developed glioma, a particularly lethal form of brain tumor, as a result of his frequent exposure to radiation, he worked with the Organization for Occupational Radiation Safety in Interventional Fluoroscopy, to be the model for a documentary about the ill effects that radiation can have on the human body. [3]
Diethrich received awards and recognition including the Frederick A. Coller Award, the presidency of the Denton A. Cooley Cardiovascular Surgical Society, the Medal for Innovation in Vascular Surgery from the Society for Vascular Surgery, and the establishment by his trainees of the Edward B. Diethrich Vascular Surgical Society. [3]
In his later years, Diethrich became an advocate for the dangers of radiation exposure incurred during his work. [8] [3] He passed away in 2017 at age 81 due to complications from a brain tumor. [9]
Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices. Diagnostic IR procedures are those intended to help make a diagnosis or guide further medical treatment, and include image-guided biopsy of a tumor or injection of an imaging contrast agent into a hollow structure, such as a blood vessel or a duct. By contrast, therapeutic IR procedures provide direct treatment—they include catheter-based medicine delivery, medical device placement, and angioplasty of narrowed structures.
Vascular surgery is a surgical subspecialty in which vascular diseases involving the arteries, veins, or lymphatic vessels, are managed by medical therapy, minimally-invasive catheter procedures and surgical reconstruction. The specialty evolved from general and cardiovascular surgery where it refined the management of just the vessels, no longer treating the heart or other organs. Modern vascular surgery includes open surgery techniques, endovascular techniques and medical management of vascular diseases - unlike the parent specialities. The vascular surgeon is trained in the diagnosis and management of diseases affecting all parts of the vascular system excluding the coronaries and intracranial vasculature. Vascular surgeons also are called to assist other physicians to carry out surgery near vessels, or to salvage vascular injuries that include hemorrhage control, dissection, occlusion or simply for safe exposure of vascular structures.
An aortic aneurysm is an enlargement (dilatation) of the aorta to greater than 1.5 times normal size. They usually cause no symptoms except when ruptured. Occasionally, there may be abdominal, back, or leg pain. The prevalence of abdominal aortic aneurysm ("AAA") has been reported to range from 2 to 12% and is found in about 8% of men more than 65 years of age. The mortality rate attributable to AAA is about 15,000 per year in the United States and 6,000 to 8,000 per year in the United Kingdom and Ireland. Between 2001 and 2006, there were approximately 230,000 AAA surgical repairs performed on Medicare patients in the United States.
A thoracic aortic aneurysm is an aortic aneurysm that presents primarily in the thorax.
Endovascular aneurysm repair (EVAR) is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair." EVAR involves the placement of an expandable stent graft within the aorta to treat aortic disease without operating directly on the aorta. In 2003, EVAR surpassed open aortic surgery as the most common technique for repair of AAA, and in 2010, EVAR accounted for 78% of all intact AAA repair in the United States.
Michael L. Marin is an American vascular surgeon. Together with Drs. Frank Veith, Juan C. Parodi and Claudio J. Schonholz, he was the first in the United States to perform minimally invasive aortic aneurysm surgery. In 2004, he was the first doctor to implant an intravascular telemetric monitor -- a device that alerts to physicians any leakage in aortic stent-grafts.
Peter Lin is an American vascular surgeon, medical researcher, specializing in minimally invasive endovascular treatment of vascular disease. He has published extensively in the area of vascular surgery and endovascular surgery.
Robert E. Michler is an American heart surgeon specializing in heart surgery, aortic and mitral valve repair, coronary artery bypass surgery, aneurysm surgery, and management of the failing heart. In 2017, Michler received the Vladimir Borakovsky Prize in Moscow from the Ministry of Health of the Russian Federation for “his personal contributions to the development of cardiovascular surgery”.

A hybrid cardiac surgical procedure in a narrow sense is defined as a procedure that combines a conventional, more invasive surgical part with an interventional part, using some sort of catheter-based procedure guided by fluoroscopy imaging in a hybrid operating room (OR) without interruption. The hybrid technique has a reduced risk of surgical complications and has shown decreased recovery time. It can be used to treat numerous heart diseases and conditions and with the increasing complexity of each case, the hybrid surgical technique is becoming more common.
Open aortic surgery (OAS), also known as open aortic repair (OAR), describes a technique whereby an abdominal, thoracic or retroperitoneal surgical incision is used to visualize and control the aorta for purposes of treatment, usually by the replacement of the affected segment with a prosthetic graft. OAS is used to treat aneurysms of the abdominal and thoracic aorta, aortic dissection, acute aortic syndrome, and aortic ruptures. Aortobifemoral bypass is also used to treat atherosclerotic disease of the abdominal aorta below the level of the renal arteries. In 2003, OAS was surpassed by endovascular aneurysm repair (EVAR) as the most common technique for repairing abdominal aortic aneurysms in the United States.
Juan Carlos Parodi is an Argentinian vascular surgeon who introduced the minimally invasive endovascular aneurysm repair (EVAR) to the world and performed the first successful endovascular repair of an abdominal aortic aneurysm on 7 September 1990 in Buenos Aires. In 1992 he was the first in the United States to perform minimally invasive aortic aneurysm surgery together with Drs. Frank Veith, Michael L. Marin and Claudio J. Schonholz. He continues to develop new techniques, including seat belt and air bag technique for cerebral protection during carotid stenting. He is recognized as a renowned pioneer in the specialty of endovascular repairs of the aorta.
