Incidental detection of single coil right ventricular lead perforation during aortic valve surgery.

It is unknown how many pacemaker and implantable cardioverter defibrillator (ICD) leads perforate during lead placement. Symptoms of a perforated lead include shortness of breath and chest pain. Signs of perforation can include a high pacing threshold, reduced lead sensing, and a high lead impedance. We present the case of a patient where perforation of the single coil right ventricular lead was not evident in imaging but incidentally detected during operative aortic valve replacement. The lead perforation rate during device implantation is around 1%-ICD leads have a higher perforation rate.
