Patient and public involvement and engagement (PPIE) is an increasingly important component of research conduct to enhance processes and potential for impact, yet is rarely critically interrogated. This paper draws on Foucauldian analysis to highlight the disciplinary powers and tensions arising in PPIE. The paper draws on a nested evaluation interview study with three PPIE members and eight academics, who had been involved in an implementation science study focused on palliative care. PPIE members were involved in the whole study and are co‐authors of this article. Through shared values and commitments to the study, a team culture of equality was developed. Yet while power was dispersed and taken‐up by all team members, in so doing a self‐governance approach within the team was developed. The pace and focus of discussions was at times more subjugating than co‐production. Identities and positions were porous; the simplistic division of ‘academic’ and ‘PPIE’ did not stand up to scrutiny, with an increasing blurring of boundaries as people’s experiences and insights changed over time. Continual, subtle, negotiations of roles, inputs and identities were manifest throughout the project. PPIE in research involves subtle, complex and ongoing disciplinary practices enacted by all members of the team. [ABSTRACT FROM AUTHOR]

Reduction ascending aortoplasty has been advocated as a possible alternative to traditional graft replacement for treatment of aneurysms of the ascending aorta and root. We report a case of a 58-year-old Jehovah's Witness female, with a 5.5-cm ascending aortic aneurysm and critical aortic stenosis. She underwent aortic valve replacement and reduction aortoplasty buttressed with a Dacron graft. We reviewed the history and contemporary applications of this technique and concluded that aortic reduction with externally supported aortoplasty may represent a viable option to treat Jehovah's Witness patients with ascending aorta and root aneurysm. , (© 2011 Wiley Periodicals, Inc.)

Primary neurogenic tumors of the heart are extremely uncommon. We report the resection of a benign primary schwannoma of the right atrium found incidentally during an aortic valve replacement. , (© 2010 Wiley Periodicals, Inc.)
