Reoperative Aortic Root Replacement in Patients with Previous Aortic Root or Aortic Valve Procedures
BACKGROUND Generalization of standardized surgical techniques to treat aortic valve (AV) and aortic root diseases has benefited large numbers of patients. As a consequence of the proliferation of patients receiving aortic root surgeries, surgeons are more frequently challenged by reoperative aortic root procedures. The aim of this study was to evaluate the outcomes of redo-aortic root replaceme...
متن کاملStentless Aortic Valve/Root Replacement
In-vitro, stentless valves have a larger effective orifice area than their stented counterparts. This is best exemplified by the fact that a 25-mm Mosaic valve, which is stented, is manufactured using a 23-mm Freestyle stentless valve. So, in order to end-up with similar effective orifice areas when implanting a stentless valve or a stented valve in the same size left ventricular outflow tract,...
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 کاملStructural Valve Deterioration After Aortic Valve Replacement with Medtronic Freestyle Stentless Porcine Aortic Root Bioprostheses
The Medtronic freestyle aortic root bioprosthesis (Medtronic, Inc., Minneapolis, MN, USA) is a stentless valve with an effective orifice area that is larger than that observed on other bioprostheses. However, there have been sporadic reports of structural valve deterioration (SVD), such as aortic root wall rupture, leaflet tearing, and pseudoaneurysm formation. We report five cases of SVD of fr...
متن کاملValve-sparing aortic root replacement and aortic valve repair in a patient with acromegaly and aortic root dilatation
Aortic regurgitation and dilatation of the aortic root and ascending aorta are severe complications of acromegaly. The current trend for management of an aortic root aneurysm is valve-sparing root replacement as well as restoring the diameter of the aortic sinotubular junction (STJ) and annulus. Our case report supports the recommendation that in patients with acromegaly, severe aortic root inv...
