Current aortic valve replacement approaches include closed heart surgery, Very invasive cardiac surgery (VICS) and Very invasive, Scapulae-based aortic valve replacement. Catheter replacement of the aortic valve (called trans-aortic valve replacement or implementation [TAVR or TAVI]) is a minimally invasive option for those suffering from ...
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.
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 ...
The surgeon then connects the separated parts of the aorta together. The surgeon then transects the pulmonary artery and aorta and frees them from surrounding tissue, then makes an incision into the right ventricle to allow them to assess the ventricular septal defect and remove excess muscle bundles in cases of extensive right ventricular ...
Aortic valvuloplasty, also known as balloon aortic valvuloplasty (BAV), is a procedure used to improve blood flow through the aortic valve in conditions that cause aortic stenosis, or narrowing of the aortic valve. It can be performed in various patient populations including fetuses, newborns, children, adults, and pregnant women.
Diagram of the human heart. Several adaptations of the Ross procedure have evolved, but the principle is essentially the same; to replace a diseased aortic valve with the person's own pulmonary valve (autograft), and replace the person's own pulmonary valve with a pulmonary valve from a cadaver (homograft) or a stentless xenograft.
The aortic valve is opened during systole, the driving force for it to open is the difference in pressure between the contracting left ventricle of the heart and the aorta. During cardiac diastole (when the heart chamber gets bigger) the aortic valve closes. [5] Aortic stenosis most commonly is the result of calcification of the cusps.
The aorta is the largest artery in the body and the descending aorta has both a thoracic and an abdominal component. A thoracic aortic aneurysm is located in the chest, and an abdominal aortic aneurysm is located in the abdomen. Not pictured here are aneurysms which span both cavities and are referred to as thoracoabdominal aortic aneurysms.
