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.
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 .
At present, there is no treatment via medication, making the timing of aortic valve replacement the most important decision to make for these patients. [4] Until recently, surgical aortic valve replacement was the standard treatment for adults with severe symptomatic aortic stenosis.
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 ...
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.
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 ...

An artificial heart valve is a one-way valve implanted into a person's heart to replace a heart valve that is not functioning properly (valvular heart disease).Artificial heart valves can be separated into three broad classes: mechanical heart valves, bioprosthetic tissue valves and engineered tissue valves.
