Bilateral anterior thoracotomy, extrapericardial patches, and endocardial
sensing lead placement have been used in 40 patients with previous
sternotomy. The mean defibrillation threshold was 15 J, and in all patients
the defibrillation threshold was less than 20 J. The surgical procedure is
simplified with less risk by avoiding dissection of previously operated
regions. Serious pulmonary complications have been avoided by adequate pain
control with epidural analgesia and early mobilization. This technique has
successfully been used in patients with underlying chronic obstructive
pulmonary disease and amiodarone- induced pulmonary fibrosis. All patients
have been extubated by the first postoperative day.
