This paper aims at proposing a reflection on the process for elaborating a bilingual lexicon of cardiology. The methodology used is that of corpus-based translation studies; that of corpus linguistics; as well as that of terminology. The material used in this study was composed of papers of cardiology written in Portuguese and translated into English and articles originally written in Portuguese and in English. Based on the lexicon proposed we have seen that there are some differences and correspondences between the use of terms in the articles from the subcorpus of study composed of original and translated texts and the use of terms in the comparable corpora in Portuguese and in English. This difference indicates that the terms are not univocal in the medical language due to the differences in use by cardiologists to name the same referents.
