 The objective of this study was to share the experience of endovascular interventions in pregnant women and women in labor gained by a national team of obstetric cardiologists. The algorithm of medical support was presented, including the cases of cardiac surgery interventions performed based on actual recommendations and the author's own experience. During 6.5 years, 2013 to 2020, 145 women and patients were admitted to the hospital, of whom 79 had cardiosurgical interventions performed. Endovascular cardiosurgical procedures were performed in 36 patients and hybrid procedures in two. Urgent and emergency endovascular interventions were performed in 17 women patients with various gestational ages 15 to 35 weeks and in two women in labor. Conditionally elective cardiosurgical interventions were performed in 17 women patients at different gestational ages, typically in the second trimester and in two women in labor. In 34 patients, the interventions were performed with the fetus in utero. This article was authored by S. Osiromica, U. V. Davidova, A. Ulymanska, and others.
