The incidence of complications following temporary epicardial pacing wires implantation remains low. Although rare, their late results may be unfavorable for the long-term operative outcome. The authors present a case of a 53-year-old male who developed a deep peristernal infection complicated by the formation of a sterno-bronchial fistula. Diagnosis, course, and possible causative factors are discussed. Retention of epicardial pacing wires as well as lung pleura laceration due to inadvertent metallic suture handling may play a role in the formation of sterno-bronchial fistula. We recommend a classic fistulography, with a simple drain fixed in the entry of the skin fistula as a route to administer the contrast medium, the diagnostic tool of choice while considering the above diagnosis.
