Fig. 1 Cardiopulmonary circuit and the cardioplegic circuit for continuous warm blood cardioplegia. The cardioplegic solution consisted of 200mL of St. Thomas’ solution mixed with 800mL of blood from a donor pig (final hematocrit, 22%). Heparin was added to a final concentration of 5,000IU/L, and potassium was adjusted to 24mmol/L. (Inf. v.cava = inferior vena cava; LA = left atrium; RA = right atrium; Sup. v.cava = superior vena cava.)

Fig. 2 Concentrations of glucose (A), total free fatty acids (B), lactate (C), and oleate (D) in the cardioplegic perfusate during 4 hours of warm continuous blood cardioplegia. The perfusate was composed as described in Figure 1. Note lack of arterial-coronary sinus difference for glucose and lactate. Results are mean±standard error of the mean (n = 8).
