Objective: Clinical benefit of mitral valve reconstruction (MVR) is well documented, but comparative data of long term follow-up (> 12months period) in postoperative quality of life (QoL) and mental power are missing. We hypothesised that mitral valve reconstruction with isolated mitral valve disease have neuropsychological benefits in 1-years follow-up.
Methods: Since 2011 40 patients (mean 60years, 75% male) after non-emergent MVR were enrolled. In a prospective trial, psychological measurements like SF-36 with 8 scaled scores about physical and mental health, depressive analysis (BDI), neuropsychological tests like Mini-Mental test (KMS), Trial A, B tests and 6-minute-walk (6MWT) for exercise tolerance was assessed before (n=38), 9days (n=34) and 12months (n=19) after surgical intervention.
Results: In a paired t-test model correcting for physical function SF-36 headings were detected significant lower scores, especially in period before vs. 9 days after the operation (p>0,001) and vs. after 12 months (p>0,001) without significances in mental power scores during the time. The 6-minute-walk measure decreased to hospital discharge date: 516m preOP vs. 438m postOP (p>0,038) vs. 526m 12months later (n.s.). Significant differences showed Part B in postoperatively period: 88min pre OP vs. 111min post OP (p>0,001) vs. 100min 12 months after OP (p>0,01).
Conclusions: The differences of QoL and neurological testing in patients with MVR in 1-years period outcome showed significant improvement as well in physical fitness (6MWT) as in SF-36 measures.
