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 .
[11] [13] In 1967 Ross took the normal pulmonary valve of a person with severe aortic valve disease, and placed it in the aortic position where the diseased aortic valve was removed. [11] To reconstruct the missing pulmonary outflow tract, a homograft stored and sterilised from a cadaver was used to replace the removed pulmonary valve. [11]
The Bentall procedure is a type of cardiac surgery involving composite graft replacement of the aortic valve, aortic root, and ascending aorta, with re-implantation of the coronary arteries into the graft. This operation is used to treat combined disease of the aortic valve and ascending aorta, including lesions associated with Marfan syndrome.
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
The details of the aortic valve repair procedure depend on the possibility of congenital malformation of the valve, the type and degree of secondary deformation, and the existence of an aortic aneurysm. The goal of the procedure is the restoration of a normal form of the aortic valve, which will then lead to near-normal function and good ...
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 ...
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.
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 ...
