RESUMEN

Pacemaker lead-associated cardiac perforation is a rare phenomenon. Lead perforations can be acute, subacute, or chronic following lead placement. Symptoms are typically nonspecific and depend on the location of the displaced lead. Diagnostic workup requires interrogation of the pacemaker and imaging studies. Management of lead displacement is dependent on multiple risk factors such as age, gender, corticosteroid use, and anticoagulation therapy. A 74-year-old female with a history of myosin light chain kinase (MYLK) 2 hypertrophic cardiomyopathy, Sjogren's syndrome, Raynaud's disease, and sick sinus syndrome was evaluated for an abnormal finding on pacemaker interrogation. The patient's only symptom was tingling of her left breast. Imaging studies confirmed pacemaker lead perforation. Right ventricle perforation due to a pacemaker lead displacement can cause severe complications. Early identification and treatment by physicians can reduce the risk of mortality.
