Primary Graft Dysfunction after Orthothopic Heart Transplantation Associated to Acute Coronary Artery Vasospasm

s S121 and peripheral O2 extraction components of pVO2. Serial measurements of PCWP in relation to CO were particularly informative based on a 2-fold PCWP-CO slope (1.5 vs. 3.1 mmHg/L/min) in the patient not explanted. Summary: Our findings suggest that reliance on LVAD explant criteria of a pVO2 > 16 mL kg/min may not adequately reflect reserve capacity and sustained recovery potential of the native heart. Enhanced phenotyping during exercise merits further investigation to refine LVAD explant criteria.
