Contribution and performance of multimodal imaging in the diagnosis and management of cardiac masses

To evaluate the contribution and performance of multimodal imaging in the diagnostic and therapeutic management of cardiac masses. We carried out a monocentric retrospective study on patients referred for cardiac mass assessment between 2006 and 2019, and analyzed the respective contribution of transesophageal echocardiography (TEE), cardiac computed tomography (CT), cardiac magnetic resonance (CMR) and 18F-fluorodeoxyglucose positron emission tomography coupled with CT (18F-FDG PET-CT). For each test, we determined strategy before and after its completion (need for another imaging or decision-making) as well as result on benign, malignant or indeterminate nature. For the 119 patients included, all imaging modalities increased decision-making rates, which rose from 2 to 54%, 23 to 62%, 31 to 85% and 49 to 100% before and after TEE, CT, CMR and 18F-FDG PET-CT, respectively (P
