Sildenafil Administration Improves Right Ventricular Function on 4D Flow MRI in Young Adults Born Premature

CONCLUSIONS: Despite reduced right atrial workload, metoprolol significantly depressed overall cardiac systolic function. Sildenafil, however, increased CI and improved RV function, as quantified by the direct flow fraction. The preterm heart appears dependent on HR, but sensitive to RV afterload manipulations.PMID:33861148 | DOI:10.1152/ajpheart.00824.2020
