CTICasesEmbolization of Ventricular Septal Defect Occluder Device
Imaging findings
Serial chest radiographs in a patient post-myocardial infarction with a ventricular septal defect (VSD) show placement of an Amplatzer occluder device. A subsequent radiograph demonstrates the device has embolized to the right main pulmonary artery. Following snare removal, a larger Amplatzer device is successfully deployed across the VSD, positioned in the ventricular septum.
Key takeaways
Transcatheter closure of post-infarction ventricular septal defects (VSDs) is a challenging procedure. Because the surrounding infarcted myocardial tissue is necrotic and fragile, the occluder device (such as an Amplatzer device) has a risk of tearing loose and embolizing into the pulmonary arterial bed. Large defects may require oversized devices or surgical patch repair.
