Left subcostal insertion of the sutureless myocardial electrode.
This report describes the use of a left subcostal extrapleural supradiaphragmatic approach to the heart for myocardial sutureless electrode insertion. Electrode insertion by this approach has consistently produced low electrode thresholds, and the ability to insert electrodes into the left ventricle or septal area of the right ventricle is considered an advantage. This technique has now been used in 52 patients. Postoperative morbidity and complications have been minimal. The procedure appears to be well tolerated in the elderly, poor-risk patient and has been a useful technique for revision of failed pacemaker systems. We believe this procedure reduces the indications for permanent transvenous pacing.
