The Utility of the Pulmonary Artery Catheter in Veno-arterial Extracorporeal Membrane Oxygenation: A Review Article
Year: 2026
Type: article
Abstract: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a life-saving intervention for refractory cardiogenic shock, yet it introduces complex alterations to cardiovascular mechanics.The management of patients supported by VA-ECMO requires precise hemodynamic assessment to navigate the complex interactions between native cardiac function and retrograde extracorporeal flow.While the routine use of the pulmonary artery catheter (PAC) has declined in general critical care, its utility in the specific context of VA-ECMO remains a subject of renewed interest and debate.This narrative review examines the physiological rationale, clinical advantages, and technical limitations of PAC monitoring in this population.We highlight the prognostic value of pulmonary artery pulse pressure (PAPP) in assessing right ventricular (RV) recovery, the critical role of pulmonary artery wedge pressure (PAWP) in detecting left ventricular (LV) distension, and the utility of invasive monitoring during weaning trials.Conversely, we discuss the significant limitations regarding thermodilution cardiac output measurement accuracy and the risks of invasive instrumentation.Current evidence supports a multiparametric approach, where PAC data is integrated with echocardiography and metabolic indices to guide precision management.
