Résumé
Patients with large hiatal hernias (HH) frequently experience postprandial dyspnea. The aim of this study was to evaluate whether feeding induced cardiac compression in these patients using echocardiography. Transthoracic echocardiography was performed during fasting and 30 min after feeding (300 g rice pudding) in patients with HHs (n = 32; mean age, 72 ± 9 years). A subset of patients (n = 15; mean age, 76 ± 6 years) were evaluated postoperatively. Preoperatively, feeding decreased left atrial (LA) volumes (maximal 27.4 ± 11.3 vs 19.2 ± 9.7 mL/m Feeding produces marked LA compression in patients with HHs, inducing compensatory exaggerated responses in cardiac inflow and hemodynamic status. These compensatory mechanisms improve postoperatively following resolution of LA compression, likely explaining the debility noted preoperatively.

BACKGROUND
Patients with large hiatal hernias (HH) frequently experience postprandial dyspnea. The aim of this study was to evaluate whether feeding induced cardiac compression in these patients using echocardiography.
METHODS
Transthoracic echocardiography was performed during fasting and 30 min after feeding (300 g rice pudding) in patients with HHs (n = 32; mean age, 72 ± 9 years). A subset of patients (n = 15; mean age, 76 ± 6 years) were evaluated postoperatively.
RESULTS
Preoperatively, feeding decreased left atrial (LA) volumes (maximal 27.4 ± 11.3 vs 19.2 ± 9.7 mL/m
CONCLUSIONS
Feeding produces marked LA compression in patients with HHs, inducing compensatory exaggerated responses in cardiac inflow and hemodynamic status. These compensatory mechanisms improve postoperatively following resolution of LA compression, likely explaining the debility noted preoperatively.
