Right Ventricular Assist Devices: Radiographic and CT Findings with Illustrations.

Right ventricular dysfunction is a critical predictor of mortality, often progressing to right heart failure, contributing to 3%-9% of heart failure admissions. Acute right heart failure is the primary cause of death in conditions such as right ventricular myocardial infarction and massive pulmonary embolism. Mechanical circulatory support with right ventricular assist devices (RVADs) has become essential in managing both acute and chronic right heart failure. Such devices provide hemodynamic support by assisting the failing right ventricle. This review outlines the mechanisms, clinical indications, and complications of these RVADs. Chest radiography and echocardiography are the primary modalities used for confirming the correct positioning of these devices, and CT is useful for evaluating intra- and extracardiac complications. These imaging modalities are vital for identifying complications and ensuring optimal device performance. As the use of RVADs grows, radiology's role in optimizing outcomes will continue to expand.
