Aortic Annular Enlargement during Aortic Valve Replacement
In the surgery of aortic valve replacement is always attempted, as much as possible, to implant the larger prosthesis with the mains goals to enhance the potential benefits, to minimise transvalvular gradient, decrease left ventricular size and avoid the phenomenon of patient-prosthesis mismatch. Implantation of an ideal prosthesis often it is not possible, due to a small aortic annulus. A vari...
متن کاملRupture of equine pericardial aortic-root patch after aortic valve replacement with aortic annulus enlargement: a case report
There are no previous reports of rupture of a heterologous pericardial patch after aortic annulus enlargement. Our patient, a 72-year-old Japanese female, presented with congestive heart failure resulting from heart compression from pseudoaneurysm formation in the aortic root. At 57 years of age the patient had undergone replacement of the ascending aorta for Stanford type A acute aortic dissec...
متن کاملAortic Root Enlargement or Sutureless Valve Implantation?
Aortic valve replacement (AVR) in patients with a small aortic annulus is a challenging issue. The importance of prosthesis-patient mismatch (PPM) post aortic valve replacement (AVR) is controversial but has to be avoided. Many studies support the fact that PPM has a negative impact on short and long term survival. In order to avoid PPM, aortic root enlargement may be performed. Alternatively a...
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...
