Abstract EN
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 O 2 (mL/kg/min) of 19.5 ± 4.3 and an actual max V O 2 of 15.5 ± 3.9, which was 80% of the predicted V O 2 .
Patients were found to have significant improvements ( P ≤ 0.01 ) in six of the nine SF-36 health parameters.
Conclusions.
In our sample of elderly patients with aortic stenosis, replacing the aortic valve with a Hancock II bioprosthesis resulted in improved hemodynamics and quality of life.
