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 .
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 aortic valve stenosis. TAVR is commonly performed by guiding a catheter from the groin to the narrowed valve via the aorta using realtime x-ray technology.
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 ...
Aortic valve repair or aortic valve reconstruction describes the reconstruction of both form and function of the native and dysfunctioning aortic valve. Most frequently it is applied for the treatment of aortic regurgitation. It can also become necessary for the treatment of aortic aneurysm, or less frequently for congenital aortic stenosis. [8]
The Hancock Aortic Tissue Valve is commonly used in patients requiring aortic valve replacement due to conditions such as aortic stenosis or aortic regurgitation. [7] The choice between a mechanical or bioprosthetic valve depends on various factors, including the patient's age, lifestyle, and medical history.
Björk–Shiley valve, as depicted in patent #US003824629. The Björk–Shiley valve is a mechanical artificial heart valve. The valve was co-invented by American engineer Donald Shiley and Swedish heart surgeon Viking Björk. Beginning in 1971, it has been used to replace aortic valves and mitral valves. It was the first successful tilting ...
