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 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 .
[31] [32] It was the first aortic valve device to receive FDA approval, in November 2011 for use in inoperable patients and in October 2012 for use in patients at high surgical risk. [33] The device is effective in improving functioning in patients with severe aortic stenosis. It is now approved in more than 50 countries. [citation needed]
Aortic valve repair may also be performed in the treatment of aortic aneurysm or aortic dissection if either aneurysm or dissection involves the aorta close to the valve. [4] Indications for aortic valve repair: Absence of relevant calcification and; Congenital and severe aortic stenosis with symptoms or decreased left ventricular function
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.
In 1962-63, Templeton implanted prostheses similar to those originally described by Sarnoff in five patients with severe aortic valve stenosis; one patient survived more than 10 years. In 1975, Bernhard and coworkers reported a reoperation in which a conduit was implanted between the left ventricle and the thoracic aorta. [ 3 ]
