Clinical case of heart failure. A 29-year-old male with a history of heart failure and an ejection fraction of 33%. After a 10-min exercise CMR protocol with a 10-W resistance increase every 2 min, his heart rate increased from 80 to 116 bpm. Real-time tagging images were acquired pre- and post-exercise in short-axis and 2-chamber views. Tagging line quality for all acquisitions in both views was good (score = 2), defined as a well-defined pattern but with partial signal intensity in saturated lines. Tagging lines demonstrated a moderate increase in myocardial deformation post-exercise. CMR cardiac magnetic resonance
