<qa>  What is the effect of RV failure early after pump implantation?Exercise capacity in continous-flow left ventricular assist device CF-LVAD patients remains severely reduced post-implant. While the effect of right ventricular RV failure early after pump implantation, and its effect on outcome has been extensively studied, the effects of late RV failure on exercise capacity and quality of life QOL has been sparsely described. Thus the purpose of this study is to examine RV function and the association to exercise capacity in CF-LVAD patients.
