Minimally invasive extracorporeal circulation in end-stage coronary artery disease patients undergoing myocardial revascularization

Abstract

Abstract Background Patients with coronary artery disease and concomitant heart failure (left ventricular ejection fraction 3 mmol/L were reported in 7 MiECC patients vs 20 cECC patients (p = 0.038), with blood glucose peak. Mean nadir hemoglobin values during cardiopulmonary bypass (CPB) were 9.7 g/dL in the MiECC group vs 7.8 g/dL in the cECC group (p = 0.044). Cardiac index during CPB was 2.4 L/min/m2 in both groups. Red blood cell units administered were 8 vs 21 units in the MiECC vs cECC group (p = 0.022). A glycemic peak was recorded in 7 patients of the MiECC group and in 20 patients of the cECC group (p = 0.037). Conclusion In end-stage coronary artery disease, the MiECC technique was associated with a higher DO2i compared to cECC. MiECC patients showed a significant reduction in red blood cell unit administration and peak intraoperative lactate levels, which correlated with better postoperative outcome.
