Immediate results of multiple minimally invasive coronary artery bypass grafting

Rationale: CABG is the gold standard of treatment for coronary artery disease. Surgery as a whole is based on the desire to optimize its results, which can be achieved by minimizing the traumatism of this operation. And in particular, the use of new minimally invasive methods is preferable with an increased risk of complications associated with artificial blood circulation, sternotomy and manipulation on the aorta. Objective: to compare the immediate results of patients operated according to the classical method through median sternotomy and patients operated through left-sided mini-thoracotomy, and to identify the advantages of one method over the other. Methods: The study group consisted of 90 patients who underwent CABG via leftsided mini-thoracotomy (group A). Control group B included 104 patients after isolated CABG via median sternotomy. The average age of patients was 63,8±7,2 years in group A and 59,9±8,1 years in group B. The body mass index in group A was 28,2±4,3 kg/m2 and in group B 31,2±4 kg/m2. All patients were diagnosed with multivessel CA lesion. The average left ventricular ejection fraction (LV EF) was 58,2±9,9% in group A and 55,7±9,1% in group B. In group A 27,8% patients and 39,4% in group B had previously performed coronary angioplasty. Results: The difference in the average duration of minimally invasive (251±88 min) and traditional (243±62,2 min) CABG was unreliable. The majority of patients in both groups operated without CPB - 92,5% in group A and 89,4% in group B. The revascularization index in the study groups was 2,6±0,9 and 3,1±0,85. The complex and longer harvesting of two IMA through a mini-step at the stage of mastering MICS CABG technology explains the less frequently performed BIMA CABG in group A (41,3%) compared to group B (71,1%, p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
