ABSTRACT
The effects of antegrade and antegrade with retrograde delivery of cardioplegic solution were evaluated in 60 patients who underwent myocardial revascularisation. All patients had triple vessel coronary artery disease and underwent revascularisation using arterial and vein grafts. Myocardial protection consisted of administration of the St.Thomas′ Hospital cardioplegic solution, topical slushed ice and systemic hypothermia (28 degrees C-30 degrees C). The patients were categorised into: group A (n=30), who received antegrade cardioplegia alone, and group B (n=30), who received antegrade and retrograde cardioplegia. With the exception of the total dose of cardioplegic solution (′p′=0.02), there was no significant difference between the two groups. Cardiac function was assessed before and after the patient was weaned from the cardio-pulmonary bypass. There was a significant increase in the right atrial pressure and a significant decrease in the mean arterial pressure from the baseline (′p′
