Pulmonary artery pressure may be a predictor of closed aortic valve in patients managed by venoarterial extracorporeal membrane oxygenation.

Pulmonary artery pressure may be a predictor of closed aortic valve in patients managed by venoarterial extracorporeal membrane oxygenation. Int J Artif Organs. 2020 Jan 31;:391398820901841 Authors: Yamaguchi S, Sawamura A, Okumura T, Kato H, Oishi H, Arao Y, Haga T, Kuwayama T, Yokoi T, Hiraiwa H, Kondo T, Morimoto R, Murohara T Abstract In the management of venoarterial extracorporeal membrane oxygenation, some patients present persistently closed aortic valve. However, little is known about the variables that contribute to persistently closed aortic valve. We investigated the factors that could predict persistently closed aortic valve at the time of venoarterial extracorporeal membrane oxygenation initiation. We investigated 17 patients who presented closed aortic valve immediately after the introduction of venoarterial extracorporeal membrane oxygenation. Patients who presented closed aortic valve 24 h after introduction of venoarterial extracorporeal membrane oxygenation were defined as the Closed-AV group (n = 8), while those whose aortic valve remained opened after 24 h were defined as the Open-AV group (n = 9). All patients were managed by concomitant use of intra-aortic balloon pumping. At baseline, there were no significant differences between mean arterial blood pressure, central venous pressure, and left ventricular ejection fraction. However, Closed-AV group had significantly lower mean pulmonary artery press...
