“…Following mechanical MVR, van Doorn et al reported that young adults perceived their quality of life and level of functioning as normal or near normal in most areas compared with a reference population [14]. Similarly, good quality of life was reported by young patients several years after mechanical AVR [16,17]. Other authors have also found that the majority of young patients return to work after valve replacement, reporting an employment rate of 67-73% one year after surgery [18,19].…”

“…The reason for higher score for ''Emotional Role'' in mechanical group might be due to some personal differences with no relation to therapeutic method. Previous studies have used SF-36 questionnaire as a standard tool for surveying the quality of life in patients with heart diseases (Maliwa et al 2003;Rahnavard et al 2006). A study on cost-effectiveness of heart valve replacement surgery in old patients, mentioned that the use of NYHA classification instead of SF-36 or EQ-5D standard tools was a weak point for their study.…”

“…There are several standardized tools widely used to measure quality of life, such as the SF 36, EuroQol-5D, Quality of Well-Being Scale, Health Utilities Index, and Health and Activities Limitations Index (Kontodimopoulos et al 2008). A study by Maliwa et al (2003) evaluated the quality of life scores of long term survivors after mechanical aortic valve replacement by using SF36 and EuroQol (EQ-5D) and compared the obtaining results with NYHA score. They conclude that at long term follow-up (mean 30 years) of patients quality of life was relatively high and it was moderately to highly associated with their NYHA class.…”

Cost-effectiveness of homograft heart valve replacement surgery: an introductory study

The clinical effectiveness of heart valve replacement surgery has been well documented. Mechanical and homograft valves are used routinely for replacement of damaged heart valves. Homograft valves are produced in our country but we import the mechanical valves. To our knowledge the cost-effectiveness of homograft valve has not been assessed. The objective of the present study was to compare the cost-effectiveness of homograft valve replacement with mechanical valve replacement surgery. Our samples were selected from 200 patients that underwent homograft and mechanical heart valve replacement surgery in Imam-Khomeini hospital (2000-2005). In each group we enrolled 30 patients. Quality of life was measured using the SF-36 questionnaire and utility was measured in quality-adjusted life years (QALYs). For each group we calculated the price of heart valve and hospitalization charges. Finally the cost-effectiveness of each treatment modalities were summarized as costs per QALYs gained. Forty male and twenty female participated in the study. The mean score of quality of life was 66.06 (SD = 9.22) in homograft group and 57.85 (SD = 11.30) in mechanical group (P < 0.05). The mean QALYs gained in homograft group was 0.67 more than mechanical group. The incremental cost-effectiveness ratio (ICER) revealed a cost savings of 1,067 US$ for each QALY gained in homograft group. Despite limitation of this introductory study, we concluded that homograft valve replacement was more effective and less expensive than mechanical valve. These findings can encourage healthcare managers and policy makers to support the production of homograft valves and allocate more recourse for developing such activities.

Understanding the quality of life after aortic valve replacement has become increasingly important. As aortic valve replacement numbers increase, more patients, physicians and families are affected by the subsequent quality of life. Quality of life information can inform the decision to perform aortic valve replacement and the selection of replacement valve. When reviewing quality of life results, it is important to realize that the findings are affected by the selection and quality of instruments, as many studies have not used valid or reliable instruments. Studies have shown that aortic valve replacement appears to significantly improve the quality of life of survivors, including those older than 70 years of age and even decades after the procedure, quality of life remains high. Studies have suggested that the elderly may gain as much quality of life benefit as younger patients. No consistent differences in resulting total quality of life have been observed between mechanical and bioprosthetic valves. Only one study showed some quality of life benefits of pulmonary autograft over mechanical valves. It is unclear whether minimally invasive aortic valve replacements confer better quality of life than standard aortic valve replacements. While existing quality of life studies have provided important information, more studies are needed especially as valve technology and operative techniques continue to improve. Future studies should endeavor to use validated general and disease-specific instruments and quantify the effects of demographics, preoperative clinical conditions and intraoperative variables on quality of life outcomes.
