Does suture technique affect hemodynamic performance of the small supra-annular Trifecta bioprosthesis?
The suture method did not affect hemodynamic performance of supra-annular bioprostheses in patients with small aortic annulus sizes. Choice of suture technique should be determined by surgeon experience and local anatomic features.
Several contextual and personal conditions consistently influenced learners' perceptions of the extent to which assessment activities were useful in informing self-assessments of performance. Although learners are not guaranteed to be accurate in their perceptions of which factors influence their efforts to improve performance, their perceptions must be taken into account; assessment strategies that are perceived as providing untrustworthy information can be anticipated to have negligible impact.
