Intracardiac masses are a relatively rare phenomenon {1, 2}. Etiology can include benign or malignant primary or metastatic tumors, tricuspid valve vegetations, and thrombi {3}. Such masses warrant scrutiny due to their potential for outflow obstruction and/or embolization. Current medical and procedural management is etiology-dependent and includes prolonged antibiotic course (with/without surgical vegetectomy), anticoagulation therapy, systemic thrombolysis, catheter-directed thrombolysis, and open surgical thrombectomy {4-10}. New endovascular techniques present a minimally-invasive treatment modality; however, there is no consensus on indications for endovascular thrombectomy {3}. The purpose of this exhibit is to summarize literature surrounding medical, surgical, and endovascular management options for intracardiac masses and to review current endovascular thrombectomy devices and techniques.
Clinical Findings/Procedure Details:
This educational exhibit will include: 1) A review of etiology, risk factors, and diagnostic means for intracardiac masses 2) A pictorial representation of common intracardiac masses and potential complications 3) A review of current literature regarding medical, surgical, and endovascular management of intracardiac masses, with an emphasis on outcomes as they relate to blood loss, rates of transfusions, and morbidity/mortality 4) A table summarizing current endovascular techniques/devices with corresponding technical and clinical success rates.
Conclusion and/or Teaching Points:
While additional research is needed to determine the efficacy of endovascular approaches in the management of intracardiac masses, many studies demonstrate high rates of technical success and low rates of blood loss and transfusions {3}. After reviewing this exhibit, IRs will have improved knowledge of intracardiac mass etiology, risk factors, diagnostic and therapeutic options, and technical considerations.
