Low cardiac output due to acute right ventricular dysfunction and cardiopulmonary interactions in congenital heart disease (2013 Grover Conference series)

摘要

The importance of right ventricular dysfunction, as a driver of symptoms and outcomes in the normal biventricular circulation, is increasingly recognized. However, the pathophysiologic mechanisms underlying the role of the right ventricle in acute and chronic hemodynamic deterioration are less well understood. This review aims to clarify the impact of acute right ventricular dysfunction on biventricular interactions and, in turn, to discuss the role of cardiopulmonary interactions in the normal circulation and when modified by the presence of associated structural malformations. Such interactions may be adverse or beneficial, and a more complete understanding of their importance may result in novel therapeutic strategies and improved outcomes.
