Nitinol wire mesh fracture and traumatic left atrial thrombus in a patient with atrial septal defect amplatzer occluder.

Although wire device frame fracture associated with thrombus formation has been reported in some types of atrial septal defect occluders, it has not been detected in patients with Amplatzer devices. Here, we describe an unusual case of Nitinol wire mesh fracture associated with left atrial endocardial damage and thrombus formation in an adult with Amplatzer septal occluder.
