Comparison of the health related quality of life of patients following mitral valve surgical procedures in the 6-months follow-up: a prospective study.

PURPOSE: The aim of the present study is to evaluate the health-related quality of life of the patients who underwent mitral valve repair (MvRp) and mitral valve replacement (MVR). METHODS: Within the scope of this prospective study design, 56 patients who had mitral valve operation between the years of 2011-2012 were enrolled in the study. 24 (42.8%) of these patients had MVR while 32 (57.1%) of them had MvRp. The health-related quality of life was evaluated according to the Turkey norms of Short Form 36 Quality-Of-Life Measures (SF-36), which were filled in by the patients before and 6 months after the operation. Moreover, preoperative risk factors affecting the quality of life (age, gender, functional capacity, rhythm, hypertension, diabetes, applied surgical method and echocardiographic results) were investigated for all the patients (n = 56) by using independent sample t test analysis. RESULTS: When the pre and postoperative changes were compared between the two groups, it was found out that there were no significant difference between the groups in terms of restraints on physical role functioning (PR), and the social role functioning values (SF) (respectively; p = 0.097, p = 0.105). However, in the comparison of pre-/postoperative changes between the groups, the changes in physical functioning (PF), bodily pain (BP), general health (GH), vitality (VT) and restraints on emotional role functioning (RE) and mental health (MH) values were found out to be significantly superior in the MvRp group than in the MVR group (respectively; p <0.01, p <0.05, p <0.01, p <0.01, p <0.05 and p <0.01). It was also confirmed that female gender, atrial fibrillation (AFR), and MVR method negatively affected the physical and mental components (respectively; p = 0.033, p = 0.003, p = 0.015). CONCLUSION: RESULTS of the SF-36 quality of life measures show that quality of life may be better in patients that have had MvRp. It should be considered that the planned surgical treatment method can affect the patient's quality of life, and this effect can indicate the success of the surgical treatment.
