Surgical techniques for implanting the automatic implantable defibrillator

Since February 1980, the automatic defibrillator was implanted in 77 survivors of multiple cardiac arrest. The subxiphoid technique was used in 28 patients and the thoracotomy technique was used in 20 patients with previous cardiac surgery. Median sternotomy was used in 29 patients undergoing open heart procedures as well as defibrillator implantation. While the subxiphoid is the most benign procedure employed, all are safe and well tolerated. The method used is determined by the clinical picture. Survival studies indicate improved survival in this high risk population.
