One-year clinical outcome after minimally invasive direct coronary artery bypass.

BACKGROUND: Minimally invasive coronary artery bypass (MIDCAB) is a new surgical technique by which the left internal mammary artery is anastomosed under direct visualization to the left anterior descending artery without cardiopulmonary bypass. METHODS AND RESULTS: We followed all 274 patients who underwent MIDCAB from the time it was introduced at a single center. In-hospital and 1-year clinical events were source-documented and adjudicated. The in-hospital major acute cardiac event rate was 2.2%; this included a 1.1% mortality rate. At 1 year, the respective rates were 7.8% and 2. 5%. When compared with the initial 100 procedures, the subsequent 174 procedures had shorter vessel occlusion times (10+/-5 versus 14+/-6 minutes; P:=0.009), times to extubation (6+/-3 versus 14+/-10 hours; P:<0.001), and lengths of hospital stay (2.1+/-1.9 versus 3. 2+/-3.1 days; P:=0.04). Cumulative 1-year adverse cardiac events were 11% in the initial 100 cases and 6% in the subsequent 174 cases (P:=0.17). CONCLUSIONS: Excellent clinical results can be achieved with the MIDCAB technique. The clinical adverse event rate may decrease with accumulated experience.

The immature-to-total neutrophil ratio (IT ratio) is a sensitive indicator of sepsis after paediatric cardiopulmonary bypass.

Cardiopulmonary bypass (CPB) causes a systemic inflammatory response syndrome (SIRS) with activation of neutrophils (increased immature-to-total neutrophil ratio, IT ratio). Does an additional inflammatory response induced by sepsis further increase the IT ratio, so that it can still be used as an indicator of sepsis? In 160 children we analysed retrospectively the IT ratios from the day before CPB to the 10th day after the operation (controls). The 95% confidence limits of the controls were plotted against postoperative day and compared with the IT ratio courses in all children of a 4-year period who developed sepsis during the first 10 days after CPB. All septic children (n = 9) had IT ratios above the upper 95% confidence limits of the controls on the day of positive culture or on the following day. The IT ratio remains a sensitive indicator of sepsis even after CPB.
