Aortic valve replacement is a cardiac surgery procedure whereby a failing aortic valve is replaced with an artificial heart valve. The aortic valve may need to be replaced because of aortic regurgitation (back flow), or if the valve is narrowed by stenosis .
Transcatheter aortic valve replacement (TAVR) is the implantation of the aortic valve of the heart through the blood vessels without actual removal of the native valve (as opposed to the aortic valve replacement by open heart surgery, surgical aortic valve replacement, AVR).
A thoracoabdominal aortic repair is a more extensive operation than either an isolated infrarenal or thoracic aortic repair. OAS is distinct from aortic valve repair and aortic valve replacement, as OAS describes surgery of the aorta, rather than of the heart valves.
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.
Valve sparing aortic root replacement (VSARR) is an alternative procedure to the composite aortic valve graft (CAGVR, Bentall procedure). A notable benefit of VSARR is the reduced need for anticoagulation, as the patient's own aortic valve is spared and does not need to be replaced with a mechanical or bioprosthetic valve. [11]
Guidelines and indications are specific to different patient populations. For adults with aortic stenosis, guidelines suggest that balloon aortic valvuloplasty (BAV) is to be used as a temporary procedure to improve blood flow through the aortic valve to alleviate symptoms and stabilize clinically before having more invasive procedures done, including aortic valve replacement (AVR) or ...
