_341_ _Objectives: _In patients with multivessel disease both the detection of the culprit lesion and the exact allocation are important preconditions for sufficient treatment and improved outcome. In a vessel based approach the combination of quantitative coronary angiography and fractional flow reserve measured by a pressure wire should be advantageous compared to myocardial SPECT, as morphological and functional information is delivered simultaneously. Therefore our aim was to evaluate MS in the detection and allocation of hemodynamically significant stenoses obtained by the (...) combined gold standard QCA plus FFR in patients with multivessel disease. _Methods: _FFR and QCA of 95 vessels in 80 patients have been evaluated. Hemodynamically significant target lesions were defined as intermediate stenoses between 50 and 75% with an FFR. (shrink)

A communities of practice framework views learning in terms of identity (trans)formation within and through participation, utilizing a set of shared resources, in a community organized around a joint endeavor, or practice. From an ethnomethodological perspective, however, the theoretical notions of community, shared resources, and identity constitute not explanatory resources, but rather topics requiring data-grounded exploration. In other words, the following empirical questions arise: If and how the participants (a) organize their group as community, (b) co-constitute a shared repertoire of (...) participatory resources, and (c) work up and manage identities as practitioners within that community. In the present study, I examine interactions at conversation analytic data sessions in Japan. The analyses focus on how the participants use terminology during their participation in doing data analysis, and how such terminology use is implicated in constituting their group as a community, and in working up and managing identities within that community.
