Common features of both techniques of the replacement process are the clamping of the aorta and the use of a length of Dacron tube (also known as an "aortic graft"), typically 5 cm, to constrict the aortic root to the normal diameter, while the patient is cooled to 20°C and placed on life support. The procedure typically takes 4 to 6 hours in ...
Prior to the advent of endovascular aneurysm repair (EVAR), OAS was the only surgical treatment available for aortic aneurysms. The shift away from open aortic surgery towards endovascular surgery since 2003 has been driven by worse perioperative mortality associated with OAS, particularly in patients in relatively frail health.

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."
The Bentall procedure is a type of cardiac surgery involving composite graft replacement of the aortic valve, aortic root, and ascending aorta, with re-implantation of the coronary arteries into the graft. This operation is used to treat combined disease of the aortic valve and ascending aorta, including lesions associated with Marfan syndrome.
Aortic aneurysm; Figure A shows a normal aorta. Figure B shows a thoracic aortic aneurysm (which is located behind the heart). Figure C shows an abdominal aortic aneurysm located below the arteries that supply blood to the kidneys. Specialty: Cardiology, Vascular surgery: Symptoms: abdominal pain and back pain: Complications: Hemorrhaging ...
The details of the aortic valve repair procedure depend on the possibility of congenital malformation of the valve, the type and degree of secondary deformation, and the existence of an aortic aneurysm. The goal of the procedure is the restoration of a normal form of the aortic valve, which will then lead to near-normal function and good ...
As of 2014, the Ross procedure comprises less than 1% of all aortic valve replacements in North America. [1] The procedure was first performed using the subcoronary method in 1967 by Donald Ross, for whom the procedure is named. [8] [11] The root replacement method was introduced in the early 1970s. [8]
Of operative risk factors, surgical site is the most important predictor of risk for PPCs (aortic, thoracic, and upper abdominal surgeries being the highest-risk procedures, even in healthy patients. [16] The value of preoperative testing, such as spirometry, to estimate pulmonary risk is of controversial value and is debated in medical literature.
