The quality of life after aortic valve replacement with homografts or prosthetic valves.

BACKGROUND AND AIM OF THE STUDY

The study aim was to evaluate the quality of life in patients after homograft or prosthetic aortic valve implantation. Evaluation was based on clinical and echocardiographic examinations, and on analysis of data from patient questionnaires.

METHODS

Patients undergoing either homograft (HV, n = 220) or prosthetic (PV, n = 220) aortic valve replacement were investigated. The patients groups were similar in age, sex, follow up period, risk factors and type of heart defect, and did not demonstrate any dysfunction of the replacement valve.

RESULTS

During both pre- and postoperative periods, no significant inter-group differences were identified with regard to the occurrence of retrosternal pain, dyspnea, palpitation, fear reaction and circulatory efficiency based on NYHA classification, and self-evaluation of physical activity assessed by patient questionnaires. The majority of patients in both groups noticed on increase in their quality of life and physical activity. The reduced sexual activity (50%) and fear reaction (30%) in both groups did not correlate with their improved sense of well-being. Up to 14.6% of PV patients did not accept the implanted valve, and 65 (29.5%) would have preferred an HV, despite the need for reoperation. Following surgery, 21% of HV patients resumed work, compared with only 7.7% of PV patients. The frequency of claims for disability pension after surgery did not correlate with the considerate clinical and subjective improvement.

CONCLUSIONS

In patients receiving either homograft or prosthetic valves, the subjective evaluation of life quality is comparable with the clinical evaluation, though the homograft valve was better accepted than its prosthetic counterpart.
