Introduction. In recent years, there has been a gradual increase in the use of circulatory support devices such as Extracorporeal Membrane Oxygenation (ECMO). This is due, among other factors, to the higher level of knowledge and training of the professional team responsible for its management. Within this team, the role of nursing is particularly noteworthy. This publication presents a care plan developed for a patient who, after undergoing surgical intervention on the mitral valve, experienced severe biventricular dysfunction requiring assistance with Veno-Arterial Extracorporeal Membrane Oxygenation. Case description. The nursing assessment was conducted following Virginia Henderson's fourteen basic needs theory, after which a care plan was developed using NANDA-NICNOC Taxonomy. Primary diagnoses included the risk of infection, as these patients undergo numerous invasive techniques. Risk of bleeding was also highlighted due to the need for cannulation of large vessels for the implantation of the Extracorporeal Circulatory Membrane, compounded by coagulation alterations. Discomfort is another key issue, emphasizing the importance of proper pain and anxiety management, as well as the vital role of the patient's family in this process. Discussion. The management of a patient with an Extracorporeal Circulatory Membrane requires adequate training by the nursing staff involved to address their specific needs, as well as potential complications that may arise during the process.
