During the 25-year BJCVS celebrations in 2011, we had the first Impact Factor (IF) published by ISI-Thomson Reuters. The prime number of 0.963, almost 1, at first evaluation, shows the high degree of development of Brazilian cardiovascular surgery. In an attempt to check the SciELO database and verify if it coincides with the 25 years of the BJCVS, we observe the best academic performance of the BJCVS (Figure 1). It should be noted that this performance was independent of international collaboration (Figure 1B). This fact deserves careful evaluation to guide our editorial planning.
