Cardiopulmonary bypass (CPB) is well known to induce a strong anti-inflammatory response. The investigators examined whether continued mechanical ventilation during CPB alters systemic immune activation.
Cardiopulmonary bypass is well known to induce a strong anti-inflammatory response. Studies had been shown that the contact of blood components with artificial surfaces, the surgical trauma, endotoxemia and a reperfusion injury are in part responsible for the seen immunological affect after surgery. The purpose of this study is to test the effect of continued mechanical ventilation during surgery on a blood marker called soluble ST2 in patients sera. Soluble ST2 acts as a decoy receptor of IL-33 and has anti-inflammatory effects. Elevated soluble ST2 concentrations are reported in patients with acute myocardial infarction, sepsis, congestive heart failure and elevates soluble ST2 levels are associated with adverse outcome.

| Lung Ventilation | Other | In the ventilated group, mechanical ventilation was done with the half of the initial tidal volume (i.e. 3-4 ml/kg, 250-300ml) during the aortic cross-clamp. |
| Measure | Description | Time Frame |
|---|---|---|
| Alteration of soluble ST2 concentration in serum | Concentration of soluble ST2 will be assessed in the serum of patient´s preoperativem, postoperative and the following five consecutive days after surgery. | Preoperative, postoperative, day 1, day 2, day 3, day 4, day 5 after surgery |
