Multivessel arterial revascularization via left anterior thoracotomy.

To present the technique and to evaluate the outcomes of the multivessel minimally invasive coronary revascularization through the left anterior thoracotomy. From July 2017 to March 2019 in 229 consecutive patients with isolated multivessel coronary artery disease we performed complete coronary revascularization through the left anterior minithoracotomy (6-8 cm skin incision). In 47 of them we performed multiarterial revascularization using left internal mammary artery (LIMA) and T-shunt with left radial artery or right internal mammary artery (RIMA). Cardiopulmonary bypass (CPB), Chitwood clamp and blood cardioplegia were used in all patients. Heart strings, encircling tapes and Chitwood clamp were used to reduce the distance from skin to coronary targets. Usual coronary instruments were used. The perioperative outcomes of multiarterial graft strategy group were compared with uniarterial graft strategy group. There were no mortality, no perioperative myocardial infarcts, and no conversion to sternotomy with either graft strategy groups. The mean number of distal anastomoses, CPB time, and total hospital stay were not different between the groups. Aortic cross-clamp time ((83.8±17.4 (45;121) vs. 67.8±17.4 (35;146), p< 0.0001) and total operation time (283.5±45 (205;495) vs. 254.3±48.6 (175;590), p=0.0003) were longer in patients with multiarterial revascularization compared to uniarterial revascularization using LIMA and veins. Multivessel coronary bypass grafting using CPB and cardioplegia can be routinely performed minimally invasively through the left anterior thoracotomy. In selected patients multiarterial revascularization could be done with excellent procedural outcomes.
