          Abstract

          Objective: Transcatheter aortic valve implantation (TAVI) is occasionally associated with stroke and silent cerebral ischemia, which may affect cognitive and functional performance. The aim of this study was to evaluate the changes in cognitive performance and functional status following TAVI. Methods: We performed a comprehensive prospective functional, cognitive and quality of life (QOL) evaluation in consecutive patients who underwent TAVI using the CoreValve device (Medtronic Inc.).The evaluation was performed at baseline and 1 month after the procedure and included the 36-item Short-Form Health Survey for QOL assessment, Mini-Mental State Examination (MMSE), quantitative clock drawing test (Rouleau), color trails test, Cognistat evaluation, Barthel Index and Duke Activity Status Index. Results: A total of 36 patients completed the full pre- and post-TAVI evaluation. Mean age was 82.2 ± 4.2 years (52.8% men); 94.5% of patients had low functional class (New York Heart Association III/IV), and 13.9% had prior stroke. After the procedure, all patients had improved functional status and valve hemodynamics. At 1 month, there was a significant improvement in the MMSE and Cognistat evaluations (from 25.9 ± 3.3 to 27.6 ± 2.4, p < 0.001, and from 5 ± 1 to 5.7 ± 0.7, p = 0.001, respectively). Conclusions: Our preliminary results of a comprehensive assessment of patients undergoing TAVI indicate favorable results for both functional performance and cognitive function early after the procedure.

            Preferences for quality of life or survival expressed by patients with heart failure.

            Eldrin Lewis, Paula Johnson, Wendy Johnson … (2001)
            As many patients with heart failure develop symptoms limiting daily life, newer therapies may be found to improve functional status without concomitant survival benefit. As some of these therapies may actually increase mortality, it is increasingly relevant to assess patients' preferences for survival vs improvement in symptoms. We enrolled 99 patients with advanced heart failure (ejection fraction 24 +/- 10, duration 6 +/- 5 years). Each patient completed time trade-off and standard gamble instruments, Minnesota Living with Heart Failure questionnaires and visual analog scales for dyspnea and overall health. Jugular venous pressure was assessed in all patients and peak oxygen consumption was measured during bicycle exercise in 60 patients. Strong polarity of preference toward either survival or quality of life was expressed by 60% of patients. There was good correlation between time trade-off and standard gamble utility scores (r = 0.64), and between preference and functional class (r = 0.60). Higher jugular venous pressure and lower peak oxygen consumption were associated with poorer utility scores (p <.05). Higher dyspnea scores and worse Living with Heart Failure scores were also associated with preference to trade time or take risks for better health. These findings suggest that heart failure patients express meaningful preferences about quality vs length of life. High jugular venous pressure, low peak oxygen consumption and poor Living with Heart Failure scores were related to low utility scores. These cannot be assumed, however, to predict the intensity of individual preference to trade nothing or virtually everything for better health.

              Health-related quality of life after transcatheter aortic valve replacement in inoperable patients with severe aortic stenosis.

              Ryan G. Webb, Anthony Smith, Vasilis Babaliaros … (2011)
              Background- Transcatheter aortic valve replacement (TAVR) has been shown to improve survival compared with standard therapy in patients with severe aortic stenosis who cannot have surgery. The effects of TAVR on health-related quality of life have not been reported from a controlled study. Methods and Results- The Placement of Aortic Transcatheter Valves (PARTNER) trial randomized patients with symptomatic, severe aortic stenosis who were not candidates for surgical valve replacement to TAVR (n=179) or standard therapy (n=179). Health-related quality of life was assessed at baseline and at 1, 6, and 12 months with the Kansas City Cardiomyopathy Questionnaire (KCCQ) and the 12-item Short Form-12 General Health Survey (SF-12). The primary end point was the KCCQ overall summary score (range, 0-100; higher=better). At baseline, mean KCCQ summary scores (35±20) and SF-12 physical summary scores (28±7) were markedly depressed. Although the KCCQ summary score improved from baseline in both groups, the extent of improvement was greater after TAVR compared with control at 1 month (mean between-group difference, 13 points; 95% confidence interval, 8-19; P<0.001) with larger benefits at 6 months (mean difference, 21 points; 95% confidence interval, 15-27; P<0.001) and 12 months (mean difference, 26 points; 95% confidence interval, 19-33; P<0.001). At 12 months, TAVR patients also reported higher SF-12 physical and mental health scores with mean differences compared with standard care of 5.7 and 6.4 points, respectively (P<0.001 for both comparisons). Conclusions- Among inoperable patients with severe aortic stenosis, compared with standard care, TAVR resulted in significant improvements in health-related quality of life that were maintained for at least 1 year.
