Successful percutaneous aortic valve implantation via a stenotic left subclavian artery access.
Summary of "Successful percutaneous aortic valve implantation via a stenotic left subclavian artery access."
Severe aortic valve stenosis may be tackled with percutaneous aortic valve replacement instead of surgical replacement. At present, two CE marked prosthetic valves are available. The CoreValve ReValving System is primarily designed to be introduced transfemorally, while implantation via subclavian arteries has been described in cases of unsuitable femoral access. However, this route has been used when subclavian artery is free of disease. In this case report we describe a successful CoreValve ReValving System implantation via a diseased and tortuous left subclavian artery after predilatation balloon angioplasty. The prosthesis was then advanced in the native aortic valve, deployed, and successfully implanted. Techniques and manipulations are provided.

Medical and Biotech [MESH] Definitions
The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.
Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).
A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE, anywhere between the aortic valve and the MITRAL VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle.
