Feasibility of conductance catheter-derived pressure–volume loops to investigate ventricular mechanics in shunted single ventricles

  • Ryan J. Butts (a1), Tain-Yen Hsia (a2) and G. Hamilton Baker (a1)

We present pressure–volume loops obtained from two patients with single-ventricle physiology, one with a modified Blalock–Taussig shunt and one with a right ventricle-to-pulmonary artery shunt. The dissimilarities in pressure–volume loop contour and related indices highlight potentially important differences in ventricular mechanics between the shunt types.
