A recipient of a dual-chamber pacing system, with a bipolar endocardial lead screwed into the right ventricular outflow tract (RVOT), developed intercostal muscle twitching. No lead perforation was identified. This observation suggests that meticulous attention should be paid to this potential complication when choosing the RVOT as a site of permanent endocardial pacing.

    ABSTRACT: The present case report describes a patient who underwent successful dual-chamber pacemaker implantation with active ventricular lead fixation at a high septal region in the right ventricular outflow tract. Unexpectedly, stimulation at a high output in the right ventricular outflow tract caused an unusual extracardiac stimulation, specifically, intercostal muscle twitching.

    ABSTRACT: A 76-year-old man received a dual-chamber implantable cardioverter defibrillator (ICD), with the defibrillator lead positioned within the right ventricular outflow tract. The lead parameters at the time of implantation were satisfactory and the post-procedure chest X-ray showed the leads were in place. The patient was cardioverted from atrial fibrillation during defibrillation threshold testing and commenced on anticoagulation immediately. One month post implantation, he experienced multiple ventricular tachycardia episodes all successfully treated with antitachycardia pacing and shocks by his ICD, but he fell and hit his chest against a hard surface during one of these attacks. He developed a massive pericardial effusion and computed tomography confirmed cardiac perforation by the defibrillator lead. Pericardiocentesis was performed and the defibrillator lead replaced with a different model positioned at the right ventricular apex. The patient made an uneventful recovery. The management and avoidance of delayed cardiac perforation by transvenous leads were discussed.

    ABSTRACT: A patient with a dilated cardiomyopathy underwent successful implantation of a cardiac resynchronization therapy defibrillator. The device system included an active fixation lead placed at the right ventricular (RV) apex. Pacing from the RV apex unexpectedly led to left-sided intercostal muscle stimulation and twitching. This intercostal muscle twitching resolved completely with movement of the lead to the RV outflow tract.
