Influence of large hiatus hernia on cardiac volumes. A prospective observational cohort study by cardiovascular magnetic resonance

The global heart function was significantly impaired by a standardized meal in the presence of a LHH. Restoration of the cardiac physiological status and improvement of clinical symptoms were noted after surgery. A multidisciplinary evaluation and CMR with a challenge meal may be added to routine pre-operative testing to select symptomatic patients for surgical hernia repair.
