Abstract

In this technical case report, we describe a 41-year-old female with a history of breast cancer who was found to have a right atrial clot attached to the tip of her Port-A-Cath. During transthoracic echocardiography to evaluate her clot, she was also noted to also have a patent foramen ovale. The decision was made to perform a simultaneous right atrial endovascular aspiration thrombectomy and patent foramen ovale closure. To minimize the risk for paradoxical embolus during clot manipulation, an intravascular embolic neuroprotection device was deployed. After the procedure, it was noted on visual inspection that the device filter contained several embolic fragments. The presence of macroscopic embolic fragments in the filter baskets highlights the role of prophylactic embolic protection when performing cardiac interventions in the setting of a patent foramen ovale, particularly in the presence of a right atrial thrombus or mass.
