Implication

Regional RV differences in normals warrant no clinical change; leaves open their alteration and utility in pathology.

Key Points

To evaluate regional differences in right ventricular systolic performance between the sinus and infundibulum using acoustic quantification echocardiography and cine magnetic resonance imaging.
Evaluated regional right ventricular function in healthy individuals using acoustic quantification echocardiography and cine MRI.
Quantified and compared regional contributions to stroke volume, fiber shortening extent, and the timing of mechanical activation across right ventricular regions.
Significant regional differences exist between the sinus and infundibular components in their relative contribution to total right ventricular stroke volume.
The sinus and infundibulum exhibit distinct degrees of myocardial fiber shortening and follow a different sequence of mechanical activation.

Outcome

Regional differences between the sinus and infundibulum components of the right ventricle with regard to contribution to stroke volume, extent of fiber shortening, and sequence of mechanical activationsurrogate

This study establishes baseline regional differences in right ventricular systolic function in normal individuals, providing a reference for future research on pathological conditions.
