Aortic Valve Sparing Operations
The treatment of aortic root and ascending aortic aneurysms often requires addressing concomitant aortic valve pathology. In the setting of aortic stenosis secondary to cusp degeneration, aortic valve replacement (AVR) is performed. However, when patients present with aortic insufficiency and normal cusp anatomy, a dilemma arises. Historically valve replacement has been performed; however, curr...
متن کاملAortic Valve Sparing Operation
A standard approach in the surgical treatment of severe aortic regurgitation and/or aortic root dilatation is Bentall procedure, it means replacement of the aortic valve and ascending aorta with a composite graft including mechanical or biological valve. The original technique described by Bentall and De Bono in 1968 (5). This is a „safe“ method with low mortality, but patients have to accept t...
متن کاملValve-sparing aortic root replacement.
The aortic root has a unique 3-dimensional configuration and the distinctive function of supporting the aortic valve and blood vessels. The sinuses of Valsalva are crucial to create appropriate eddy currents that are important in initiating and coordinating aortic valve closure and promoting coronary artery blood flow. Most aneurysms in the aortic root are associated with degenerative changes i...

متن کاملAortic Valve Sparing Operations: A Review
Aortic valve sparing operations were developed to preserve the native aortic valve during surgery for aortic root aneurysm as well as surgery for ascending aortic aneurysms with associated aortic insufficiency. There are basically two types of aortic valve sparing oprations: remodeling of the aortic root and reimplantation of the aortic valve. These operations have been performed for over two d...
