Post-cardiac Injury Syndrome Following Permanent Dual-Chamber Pacemaker Implantation

Post-cardiac injury syndrome is a heterogeneous group of conditions that result from autoimmune-mediated inflammation of the pericardium, epicardium, and myocardium. Interventions such as pacemaker lead insertions, percutaneous coronary interventions, radiofrequency ablations, cardiac surgeries, and Swan-Ganz catheterizations can cause myocardial injury leading to post-traumatic pericarditis. This phenomenon can lead to chest pain, recurrent effusions, and fever along with possible complications of heart failure, arrhythmias, conduction abnormalities as well as cardiac tamponade. Herein, we present a case report of a 64-year-old female with a history of sick sinus syndrome managed with a dual-chamber pacemaker who presented with post-cardiac injury syndrome after three months of pacemaker implantation. She developed a recurrent syndrome of fever, chest discomfort, tachycardia with weakness, hemodynamic instability, hemorrhagic serositis, and cardiac tamponade. The mechanism of exudative inflammatory effusions initially remained inconclusive, as the workup for infectious and malignant processes was negative. However, post-cardiac injury syndrome akin to the Dressler syndrome related to screw-in dual-chamber pacemaker implantation remained a possibility. Her condition was acutely managed with a combination of colchicine and glucocorticoid therapy. She was placed on long-term aspirin and colchicine therapy to prevent any recurrences. This article illustrates a case of post-cardiac injury syndrome after dual-chamber pacemaker implantation, including details of evaluation, management, complications and monitoring of patient progress.
