Abstract
Although there are extensive published data regarding venous-arterial (VA) ECMO, particularly in the pediatric population, there is a paucity of data (mainly including case reports and observational studies) delineating the role of echocardiography in the management of adult patients supported by venous-venous (VV) ECMO. The present review is aimed at specifically addressing the rationale for echocardiography use in patients supported by VV-ECMO and at summarizing the available evidence on this topic. Based on the available evidence and on the experience of our group, practical considerations on the use of echocardiography in adult patients on VV-ECMO support are reported. To date, echocardiography is mainly used for selecting the type of ECMO (VA vs VV), monitoring cannulation and the early detection of complications, but it is underused in patients supported by VV-ECMO. Nevertheless, in these patients, this methodology can provide useful information in monitoring cardiac function, cannula positioning, pericardial fluid (for early detection of tamponade) during ECMO support, and therefore it can contribute to the integrated assessment and management of these complex patients. There is a clinical need to elaborate shared protocols for echocardiography use during VV ECMO support, particularly at this time when advanced echocardiography is gaining interest among intensivists.
