Aortic 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 کاملOperative implications of the small aortic root
Methods Our study comprises of 46 patients operated during the last 3 years in the IInd Cardiovascular Surgery Department who received 19 and 21 mm aortic valves. There were 20 males (43.48%) and 26 females (56.52%) in our cohort. The mean age was 57 years (ranging from 17 to 78).

متن کاملThe use of CorMatrix extracellular matrix for aortic root enlargement
This manuscript presents a published record of the use and efficacy of the extracellular matrix CorMatrix and why it may be superior to other materials used for aortic root enlargement. The potential benefits of an extracellular matrix are the natural ingrowth and development of native arterial cells and structure.
متن کاملAortic root dynamics are asymmetric.
BACKGROUND AND AIM OF THE STUDY The presence of conformational changes in the aortic root during the cardiac cycle is well known, but precise information on time-related changes at each level of the root is lacking. METHODS High-resolution, 3D sonomicrometry (200 Hz) was applied in an acute sheep model. Twelve crystals were implanted in eight sheep at each base (n = 3), commissure (n = 3), si...
