Objective: To determine the e cacy of a sternal wire system in secondary sternal dehiscence after repeat closure of the sternum, following surgical revision after open heart surgery. Place and Duration of Study: Department of Cardiovascular Surgery, Zonguldak Bülent Ecevit University, Zonguldak, Turkey; and Turkey Yuksek Ihtisas Training and Research Hospital, Turkey, from January 2015 to May 2019. Methodology: Patients, who underwent open heart surgery with median sternotomy, were included in this retrospective study. The patients were divided into two groups, according to the sternal closure material. The time of the sternal reconstruction surgery, because of sternal dehiscence, fracture, broken sternal wire(s) or cable(s) after the rst revision surgery, was noted for each patient. Results: A total of 389 patients were identi ed. Group 1 included 72 (50%) patients whose sternums were closed with a sternal cable system; and Group 2 included 72 (50%) patients whose sternums were closed with conventional steel wires after propensity matching. The duration of cardiopulmonary bypass, number of intra-aortic balloon pumps used, and number of extracorporeal membrane oxygenators used were signi cantly higher in Group 1 (p = 0.007, p = 0.034, and p = 0.028, respectively). The number of emergency operations was signi cantly higher in Group 2 (p = 0.021). There was no signi cant di erence in terms of secondary sternal dehiscence between the groups (p = 0.366). Conclusion: Application of the sternal wire system in revisional open heart surgery is not more e ective than conventional steel wire at preventing secondary sternal dehiscence.
