This paper presents the development of a video-language model for automating the interpretation of echocardiographic images used for assessing cardiac function. To overcome the limitations of existing medical video-language models, which rely on single-frame (image) inputs and thus have limited accuracy in diagnosing diseases that can only be diagnosed through cardiac motion, we present a model that processes full echocardiographic video sequences in five standard views. Trained on 60,747 echocardiographic video-report pairs, we evaluate the improved retrieval performance due to video input and multi-view support, as well as the contribution of various pretrained models.
