Effect of prior sternotomy on mortality and morbidity after heart transplantation. Cardiac Transplant Team.
A retrospective analysis to evaluate the impact of prior sternotomy on the outcome of cardiac transplantation was undertaken. Some 165 patients who received primary heart transplantation were classified into three groups. There were 102 patients in group 1 (no prior sternotomy), 47 in group 2 (one prior sternotomy), and 16 in group 3 (more than one prior sternotomy). The three groups were demographically similar. Coronary artery bypass was the indication for prior sternotomy in 77% of patients in group 2 and in 94% in group 3. Mortality within 30 days post-transplant was significantly different among the three groups (group 1, 7.8%; group 2, 8.5%; group 3, 31%; P = 0.0148). The 1-year actuarial survival was also significantly lower in group 3 (52%) compared with groups 1 (83%) and 2 (81%) (P = 0.0311). Multivariate analysis identified more than one prior sternotomy and pulmonary hypertension as risk factors for death within 30 days post-transplant. Patients who had prior sternotomy also had a higher incidence of coagulopathy (group 1, 17%; group 2, 49%; group 3, 38%; P = 0.0002), and re-exploration due to excessive bleeding (group 1, 5%; group 2, 11%; group 3, 25%; P = 0.0225). Requirement for blood products for transfusion was also higher in groups 2 and 3. There was no significant difference among the three groups in the incidence of early infections (50% versus 53% versus 44%), renal failure (6% versus 11% versus 19%), or allograft rejection in patients who survived the first 30 days (95% versus 86% versus 82%).(ABSTRACT TRUNCATED AT 250 WORDS)
