Illustrative clinical case. A 60-year-old male with worsening upper chest heaviness and shortness of breath with exertion. Stress echo showed focal systolic dysfunction with hypokinesis of the left-ventricular basal inferoseptum and inferior walls at both rest and stress. Similarly, during an exercise CMR protocol, real-time cine with deep learning-based radial acceleration showed hypokinesis of the left-ventricular basal inferoseptal wall during rest and at post-exercise stress (arrows). Subsequent coronary angiography revealed a heavily calcified right coronary artery (arrow) with serial subtotal occlusions
