OBJECTIVES: Minimally invasive valve surgery (MIVS) is associated with improved clinical outcome but longer cardiopulmonary bypass (CPB) time. The aim of the present study is to compare inflammatory and coagulation parameters in patients undergoing minimally invasive or standard valve surgery. METHODS: A prospective non-randomized study was performed enrolling 79 patients undergoing mitral (20 right mini-thoracotomy and 18 standard sternotomy) and aortic valve (20 mini-sternotomy and 21 standard sternotomy) procedures. Blood samples were collected perioperatively to measure prothrombin fragment 1.2 (PF1.2, thrombin generation), plasmin antiplasmin complex (PAP, fibrinolysis), interleukin-6 (IL-6, inflammation). Plasma free haemoglobin (f-Hb) was assessed to evaluate haemolysis. RESULTS: Patients in the minimally invasive group were younger and had less comorbidities CPB and cross-clamp times were comparable considering both aortic and mitral procedures, but longer in the mini-thoracotomy group. IL-6 and PAP were reduced in the minimally invasive group, particularly 2 h after CPB (respectively 102 ± 114 vs 34 ± 49 pg/ml, P < 0.001 and 2137 ± 1046 vs 1207 ± 675 ng/ml, P < 0.001), PF1.2 was also reduced during and after the operation (688 ± 514 vs 571 ± 470, P = 0.02; 1600 ± 1185 vs 1042 ± 548, P < 0.001; 1487 ± 676 vs 1042 ± 541). Despite the use of vacuum-assisted active venous drainage (VAVD) f-Hb was significantly reduced in the minimally invasive group. The other routine biomarkers such as C-reactive protein, fibrinogen and cTnI were also reduced in the minimally invasive group. CONCLUSIONS: In a selected cohort of patients MIVS is associated to reduced inflammatory reaction and coagulopathy, supporting the clinical evidence of reduced postoperative bleeding and lower transfusion rate. Our data offer further suggestion supporting the adoption of minimally invasive approaches.
