Efficacy and safety of "2-staged" Hybrid Coronary Revascularization Using Bilateral Internal Thoracic Artery Y Graft for Patients With Multivessel Coronary Artery Disease / 中国循环杂志

ABSTRACT

Objectives: To explore the feasibility and safety of "2-staged" hybrid coronary revascularization using bilateral internal thoracic artery (BITA) for the treatment of multivessel coronary artery disease. Methods: Data of 65 patients who underwent "2-staged" hybrid technique (HCR) using BITA (BITA-HCR group) in our heart center because of multivessel coronary artery lesions during 2014.05-2017.05 were retrospectively analyzed. Results were compared with 96 patients who underwent "2-staged" HCR with single ITA (SITA-HCR group) by the same surgeon over the same time period. Results: There was no significant difference of preoperative characteristics between two groups. Operation time was significantly longer [(204.6±28.7) min vs (147.9±31.6) min, P<0.05], number of distal anastomoses was significantly higher [(2.2±0.5) vs (1.0±0.0), P<0.05], number of stents was significantly lower [(1.90±0.67) vs (2.40±0.49), P<0.05] in BITA-HCR group than in SITA-HCR group. Bleeding volume [(520.1±120.3) ml vs (532.2±350.3)ml, P>0.05], mechanical ventilation time [(7.7±3.2) h vs (6.9±2.3) h, P>0.05] and blood transfusion required [5(7.7%)vs 8(8.3%), P>0.05] were similar between the two groups. Conclusions: The "2-staged" hybrid procedure using BITA is safe and feasible for the revascularization of multiple coronary artery lesions.
