Abstract
Background Since biological valve recipients are likely to need a redo procedure in the future
for valve deterioration, we hypothesized patients might be more fearful about the
progression of their disease than patients after aortic valve replacement (AVR) with
a mechanical valve. The aim of this study is to compare the quality of life (QOL)
and anxiety in patients who have undergone biological versus mechanical AVR.
Method A total of 56 patients after mechanical AVR (mean age: 64.4 ± 8.17 years) and 66
patients after biological AVR (mean age: 64.8 ± 11.05 years) received three questionnaires
5.66 (± 2.68) years after surgery, including: The short form-36 (SF-36) to assess
QOL, the fear of progression questionnaire (FOP), and the cardiac anxiety questionnaire
(CAQ) to assess general anxiety, anxiety related to cardiac symptoms, and anxiety
about progression of heart disease and valve and anticoagulation-specific questions.
Results No significant differences were found for all categories of the SF-36. The FOP showed
significantly favorable values for the biological AVR group. The CAQ showed a tendency
in the subscale “avoidance” (i.e., avoidance of pulse increase) and “attention” towards
more favorable values for the biological AVR group.
Conclusions In contrast to our hypothesis, patients after mechanical AVR show significantly higher
anxiety values for the FOP, and a tendency toward higher values for “avoidance” (i.e.,
avoidance of pulse increase). Partnership concerns, especially in terms of sexuality
can be explained by factors that are recognizable for the partner, such as valve sound.
These data provide evidence that factors that are continuously present after mechanical
AVR, such as valve sound or anticoagulation might affect wellbeing stronger than the
certainty of reoperation in the future after biological AVR. We conclude that implantation
of a biological prosthesis can be justified in younger patients with regards to QOL.
