A 44-year-old man who received left ventricular assist device (LVAD) implantation for end-stage heart failure due to dilated cardiomyopathy suffered from mediastinitis. Computed tomography confirmed mediastinitis. His mediastinum was reopened and irrigated. Negative pressure wound therapy (NPWT) was applied to the wound without closing the chest. This system enabled the patient to receive early physical rehabilitation. One year after LVAD implantation, under NPWT, the patient could walk in the general ward, and was waiting for cardiac transplantation. We used some useful materials for NPWT including a coatable non-alcoholic film, flexible sealing sheet, soft exudate absorber, in order to control wound clean, keep air-tight, prevent damage to the skin and to reduce mediastinal instability. LVAD implantation is usually performed as a bridge to transplantation or recovery. One of the most critical complications is intractable mediastinitis. We described a successful infection control of LVAD related mediastinitis with the NPWT.

Purpose: The purpose of this study was to examine the reliability and validity of the behavioral intention scale for end-of-life discussions. Methods: The scale items were developed according to the Theory of Planned Behavior. The drafts of the scale were created by Item-Level Content Validity Index (I-CVI) and a preliminary test. In the main study, we administered a cross-sectional questionnaire on the web to the participants 20–79 years of age (n=860), living in Tokyo and six surrounding prefectures, and a retest one week later (n=665). We examined item analysis, calculation of a reliability coefficient (intraclass correlation coefficient, Cronbach's alpha coefficient), construct validity, and concurrent validity of the scale. Results: Six factors identified by an exploratory factor analysis were; outcome evaluation, perceived power, control beliefs, motivation to comply, normative beliefs, and behavioral beliefs. The alpha coefficient of the overall scale was .96. The effect size that was determined based on known-groups validity and the correlation coefficient determined on the basis of concurrent validity were moderate. Conclusions: The reliability and validity of the scale were generally confirmed.
