Abstract
Objective: To analyze the main heart diseases in pregnancy, emphasizing their interference and associations with complications and outcomes in the pregnancy-puerperal cycle. Methods: This is an integrative literary review study in which data collection was carried out in the databases of the Online Electronic Scientific Library (SciELO), Latin American and Caribbean Literature (LILACS) and PubMed, using “Heart Diseases” as descriptors, "Pregnancy" and "High-risk pregnancy". The data were analyzed and discussed with the current literature. Results: From the analysis of the articles, rheumatic and congenital heart diseases were identified among the main alterations. The most frequent complications were heart failure, arrhythmias and thromboembolic events. Hypertensive syndromes and hemorrhagic conditions were associated with increased morbidity and mortality in pregnant women. In view of these problems, some aspects of clinical management in pregnant women were scored. Final considerations: It is concluded that the heart diseases are an important cause of morbidity and mortality during pregnancy and increase the risk of obstetric complications. Thus, it is important to provide individualized, early and multidisciplinary care to these pregnant women, to minimize maternal-fetal complications.
