Epicardial pacing wire (EPW) insertion is an integral part of open heart surgery. However, the use of EPW insertion is also associated with complications such as bleeding, tamponade, arrhythmias, and occasionally even death of the patient. Various techniques have been described for preparing, placing, and removing EPW. We present our simple, yet effective technique of preparing, inserting, and removing EPW where the incidence of complications is nil.

| Introduction|| |
Epicardial pacing wire (EPW) insertion is an integral part of open heart surgery. However, the use of EPW insertion is also associated with complications such as bleeding, tamponade, arrhythmias, and occasionally even death of the patient. Various techniques have been described for the usage of EPW. Herein, we present our simple, yet effective technique of preparing, inserting, and removing EPW; with its use, the incidence of complications is nil.

Commercially disposable EPW is available with an insulating layer which encloses the wire which is supplied with a curved metallic needle, on the one end, for the passage through the myocardium and a straight needle, on the other end, for the passage through the chest wall [Figure 1]a.

Under all sterile precautions, the insulated portion of the distal 1–1.5 cm of the EPW is circumferentially partially cut using 15 knives to expose the underlying metallic wire [Figure 1]b. The noninsulated wire along with its needle is cut from the base of the distal insulated portion [Figure 1]c. The partially cut insulated portion of the wire is now gently slid distally on the noninsulated wire for 2–3 mm [Figure 2]a. The distal insulated portion of EPW should be kept up to 5–8 mm, not longer. Consequent to this, the distal end of the EPW tip will now be covered by an insulated atraumatic material [Figure 2]a. Consequent to this, there will be 3–4 mm bare metal wire between the proximal and the distal insulated portion of the EPW [Figure 2]a. This bare noninsulated portion of the wire is atraumatic and can be fixed on to the myocardium with 6-0 or 7-0 proline suture [Figure 2]b and [Figure 3]. As a consequence of this, the distal portion of the wire is now fully covered with the insulated rubber/plastic sheath and is atraumatic to the adjacent structures [Figure 2]b and [Figure 3]. Because of the small portion of bare wire that is in contact with heart, threshold problem resulting from a larger area of contact is minimized. Hence, with this technique, there is no chance of any injury to any adjacent structures. The wires are removed by constant gentle traction, allowing the motion of the heart to assist the dislodgement. We have observed that the distal end of insulation is absent on removal of the wire. However, we have never observed any complication attributable to retained distal insulation cover, and we have never experienced a wire that could not be removed. All patients are subjected to 12-lead electrocardiogram following wire removal, and none of them had any ventricular arrhythmias.

| Discussion|| |
Epicardial pacing is often the best and sometimes the only method for treating temporary rhythm disturbances that often occur in the postoperative management of critically ill cardiac patients. There is a small but definite risk of injury to adjacent structures due to the placement of EPWs. Further, the removal of these wires postoperatively can potentially lead to serious bleeding episodes necessitating surgical intervention. Bougioukas et al. have reported in a series that the removal of EPW could be recognized as a definite cause of bleeding in eight cases of the total of 4244 patients (0.2%), accounting for 3.6% of all re-explorations for bleeding. The outcome in two patients was fatal, wherein the intraoperative findings confirmed acute pericardial hemorrhagic effusion. The other complications of EPW include infection, myocardial damage, ventricular arrhythmias, perforation, and tamponade.,
Several serious and somewhat bizarre complications have been described in the literature after the removal of EPW.,,, A major problem with all techniques of EPW placement is the development of an inflammatory reaction around the wire/myocardium interface, and EPW usually fails to sense and capture after 5–6 days. We have never come across issue with our technique. Only 2–3 mm (size of small clip) of distal covering of insulated part of pacing wire remains in the pericardial cavity. We have not encountered any problem due to this foreign body till now. We believe that our technique of placing EPW is atraumatic and does not create any inflammatory reaction within myocardium.
Every year, we perform nearly 5000 cardiac surgeries. We initially had complications due to injury to adjacent cardiac structures by EPW needing emergency re-explorations. For the past 12 years, we are using our modified technique for preparing and placing EPWs. With this modified technique, we have never had any re-exploration due to injury from EPW.
| Conclusion|| |
We conclude that our modified technique of preparing and fixing the EPW is very simple and safe and is free from any untoward complications.
