Background
Heart failure is a clinical condition characterized by the heart's inability to pump sufficient blood to meet the body's demands. Left ventricular assist devices (LVADs) have emerged as a vital therapeutic option for patients who suffer from advanced heart failure, bridging the gap between medical management and cardiac transplantation. As the utilization of LVADs has increase, so has the necessity for imaging to evaluate device placement, functionality, and potential complications. This educational exhibit aims to provide a comprehensive understanding of the role of imaging in assessing LVADs.
Educational Goals / Teaching Points
Appreciate the clinical indications for LVAD implantation. Acquaint with the various LVAD types in current clinical practice. Recognize standard appearances of LVAD on imaging modalities. Identify common LVAD-related complications on imaging.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The intricacies of heart failure, its progressive nature, and the heart's altered anatomy and physiology once an LVAD is in place are pivotal. LVADs, while alleviating symptoms and enhancing survival, present unique challenges due to potential complications such as fluid collections, the formation of biodebris around the device, infection, and device malfunction. Different imaging modalities, such as radiographs and chest CT, have distinct roles in LVAD assessment. The exhibit will discuss the importance of proper CT imaging in visualizing both standard LVAD placements and potential complications. Common LVAD types and their typical imaging characteristics, as well as imaging signs of complications, will be illustrated.
Conclusion
With LVADs becoming an integral part of heart failure management, radiologists must be familiar with the imaging evaluation of these devices. This education exhibit offers a structured approach to understanding the normal LVAD imaging as well as complications that arise with LVAD use, promoting improved patient care.
