ICD implantation via thoracoscopy without the need for sternotomy or thoracotomy.
After development of the technique in mongrel dogs, implantable cardioverter defibrillator (ICD) patch and sensing lead implantation was attempted via thoracoscopy, without sternotomy or thoracotomy, in three patients. Two large titanium mesh defibrillator patches and two "screw-in" epicardial sensing leads were applied without difficulty in each of two patients. In a third patient, satisfactory placement of the defibrillator patches could not be achieved via thoracoscopy, necessitating thoracotomy. Defibrillation threshold (DFT), cardioversion energy requirement (CER), and rate and morphology signals in those patients with successful thoracoscopic implantation were comparable to those achieved by open technique. We conclude that ICD patch and sensing lead implantation via thoracoscopy is feasible.
