To manage postcardiotomy patients with cardiopulmonary bypass support (CPS), it is very important to evaluate the native cardiac function. In 5 postcardiotomy cases without CPS, the alternative thermodilution outputs by right ventricular (RV) injection were compared with simultaneous thermodilution outputs by standard right atrial (RA) injection. Cardiac output determined by RV injections, ranging from 3.4 to 10.1 L/min, showed close agreement with the values by RA injections (r = 0.993). Four cases with postcardiotomy profound heart failure were placed on femoral venoarterial CPS and managed with monitoring native cardiac output determined by an RV injection thermodilution method. It was very easy and reasonable to decide the pump flow relative to native cardiac output. The cardiac output determined by RV injection provides a means of accurate evaluation for the failing heart in postcardiotomy cases with venoarterial CPS and optimizes the staged weaning off CPS or the change to a pneumatic pulsatile ventricular assist device for long‐term assist.
