Murat Yuce, Vedat Davutoglu, Ibrahim Sari and Orhan Ozer Atrial Septal Defect Occluder Device Huge Thrombus in Patient with Low Ejection Fraction Echocardiography 27
Successful Amplatzer occluder device implantation was performed to a 45-year-old male with atrial septal defect (ASD) and heart failure (EF:30%). Two months after discharge, huge device thrombus and left atrium spontaneous echo contrast (SEC) were detected. He had discontinued aspirin and clopidogrel 1 month after the procedure. Unfractionated heparin was commenced and tirofi ban was added. After 7 days, thrombus completely disappeared but SEC persisted. Thrombus of ASD occluder device usually resolves after anticoagulation therapy. This is fi rst report of device thrombus, which evolved possibly due to atrial stasis stemming from cessation of shunt in setting of low ejection fraction.
