Averaged chest radiographs and overlaid saliency maps for tricuspid regurgitant velocity greater than 2.8 m/s. The top image shows the averaged chest radiographs from the test dataset, generated by averaging the top 10% of true positive images. The bottom image shows the average of the saliency maps associated with the chest radiographs overlaid onto the averaged chest radiographs. All saliency maps mainly highlight the cardiac shadow area.
