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 ...
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]
[1] [4] It is an alternative to a mechanical valve replacement, particularly in children and young adults. [7] It avoids the need for thinning the blood, has favourable blood flow dynamics and the valve grows as the person grows. [7] The most common reason for performing the Ross procedure in children and young adults is for bicuspid aortic ...
An aortic homograft is an aortic valve from a human donor, retrieved either after their death or from a heart that is removed to be replaced during a heart transplant. [12] A pulmonary autograft, also known as the Ross procedure , is where the aortic valve is removed and replaced with the patient's own pulmonary valve (the valve between the ...
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 .
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 an aortic aneurysm, less frequently for congenital aortic stenosis. [53]
Valve replacement surgery is the replacement of one or more of the heart valves with either an artificial heart valve or a bioprosthesis (homograft from human tissue or xenograft e.g. from pig). It is an alternative to valve repair .
St Jude Medical's Portico Transcatheter aortic valve received European CE mark approval in December 2013. The valve is repositionable before release to ensure accurate placement helping to improve patient outcomes. [12] Edwards' Sapien aortic valve is made from bovine pericardial tissue and is implanted via a catheter-based delivery system. It ...
