May warrant urgent surgical consideration for obstructive pacemaker lead thrombus; leaves open optimal strategies pending higher-level evidence.
A 75-year-old man was admitted to our hospital with a complaint of progressive dyspnea with effort. The patient had a permanent pacemaker that was implanted 16 years ago. Transesophageal echocardiography revealed a large, mobile mass in the right atrium attaching to the insertion site of the atrial lead at the tricuspid valve level. Because of the size, mobility, and location of the mass, urgent surgical removal was considered. The mass was successfully removed. Histologic examination of the mass demonstrated a partially organized thrombus. The postoperative course was uneventful and the patient's symptoms improved remarkably after operation.

Tuğcu et al. (2009) conducted a case report in Right atrial pacemaker lead thrombosis causing tricuspid inflow obstruction (n=1). Urgent surgical removal of right atrial thrombus was evaluated on Thrombus removal and symptom resolution. Urgent surgical removal of a right atrial thrombus attached to a 16-year-old pacemaker lead successfully relieved tricuspid inflow obstruction and dyspnea in a 75-year-old man.
