Right atrial pacemaker lead thrombosis causing tricuspid inflow obstruction.
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.
