Purpose: A temporary epicardial pacing wire (TEPW) has been routinely placed in patients undergoing cardiac surgery. However, its fixation or removal occasionally causes troublesome complications. The aim of this study is to develop a novel TEPW using biodegradable film to fix the electrode to the epicardium without needle stabbing. Description: A biodegradable film was prepared with poly(L-lactide-co-ε{lunate}-caprolactone). The film has a honeycomb-patterned structure that serves as a temporary adhesive for the myocardial surface, and the electrode was incorporated within the film. The novel TEPW was placed on the ventricular epicardium of dogs (group A, n = 5). As a control, conventional TEPW was inserted (group B, n = 6). The pacing threshold, R wave amplitude, impedance, and slew rate were measured at postoperative days 0, 1, 3, 5, 7, and 14, and complications after removal were checked. Evaluation: All measurements in both groups were identified and differences were not observed. In addition, the novel TEPWs could be easily removed without related complications. Conclusions: This novel TEPW is safe and feasible for postoperative management of cardiac surgeries.
