It was with great interest that I read this work by Lacour-Gayet and colleagues [1] outlining a proposed conformational change for the extracardiac Fontan coupled with an axial-flow pump as a strategy for optimizing hemodynamics during mechanical cavopulmonary assistance of the univentricular circulation, the "artificial right ventricle (ARV)."
The paradox of the Fontan is the presence of simultaneous systemic venous hypertension and pulmonary arterial hypotension [2]. This current work builds upon the first experiments outlining mechanical cavopulmonary assistance for failing univentricular circulation, published by Rodefeld and colleagues in 2003 [3], which assessed the use of axial-flow pumps positioned in both the superior and inferior
