[Influence of patient-prosthesis mismatch in the octogenarian undergoing surgery for aortic valve replacement due to severe stenosis].

Introduction And Objectives: The clinical impact of patient-prosthesis mismatch on the outcome in octogenarians who undergo surgery for aortic valve replacement due to severe stenosis is unknown. Our objective was to quantify the frequency of some degree of patient-prosthesis mismatch and its impact on mortality and life quality.

Methods: We analyzed all the octogenarian patients who underwent surgery for aortic valve replacement due to severe stenosis in our center from February 2004 to April 2009.
