Background: This study aims to investigate the effects of reoperative sternotomy on early and long-term outcomes after heart transplantation.

Methods: We retrospectively reviewed data of a total of 92 patients (72 males, 20 females; mean age 36 years; range, 3 to 61 years) who underwent orthotopic heart transplantation between May 1998 and July 2014. The patients were divided into three groups. Group A (n=23) included patients who underwent previous cardiac surgery with sternotomy other than ventricular assist device implantation; Group B (n=12) included patients who were bridged-to-transplant with a ventricular assist device; and Group C (n=57) included patients who for the first time underwent heart transplantation without previous sternotomy. Preoperative and operative data of the three groups were compared. The short- and long-term outcomes of all groups were analyzed.

Results: There was no significant difference among the groups, except for the age and preoperative international normalized ratio. Total ischemia time in the ventricular assist device group was longer than Group C. The length of intensive care unit stay was also longer in the ventricular assist device group than the other groups. The amount of postoperative chest tube drainage and blood transfusion was higher in Group A. Early mortality rate was significantly higher in Group A. There was no significant difference in survival among the three groups in the long-term. According to the logistic regression analysis, no variable was found to be a significant risk factor for mortality.

Conclusion: Reoperative sternotomy other than ventricular assist device implantation was found to be a risk factor for early mortality; however, mid and long-term survival rates were similar to patients in whom transplantation was the primary procedure. In patients with reoperative sternotomy, heart transplantation can be performed with similar risks to patients without resternotomy with careful selection and accurate pre- and intraoperative surgical approach.
