PG - 151282 LID - 10.1155/2014/151282 [doi] LID - 151282 AB - Background and Aim. While aortic valve replacement for aortic stenosis can be performed safely in elderly patients, there is a need for hemodynamic and quality of life evaluation to determine the value of aortic valve replacement in older patients who may have age-related activity limitation. Materials and Methods. We conducted a prospective evaluation of patients who underwent aortic valve replacement for aortic stenosis with the Hancock II porcine bioprosthesis. All patients underwent transthoracic echocardiography (TTE) and completed the RAND 36-Item Health Survey (SF-36) preoperatively and six months postoperatively. Results. From 2004 to 2007, 33 patients were enrolled with an average age of 75.3 +/- 5.3 years (24 men and 9 women). Preoperatively, 27/33 (82%) were New York Heart Association (NYHA) Functional Classification 3, and postoperatively 27/33 (82%) were NYHA Functional Classification 1. Patients had a mean predicted maximum V O2 (mL/kg/min) of 19.5 +/- 4.3 and an actual max V O2 of 15.5 +/- 3.9, which was 80% of the predicted V O2 . Patients were found to have significant improvements (P
