Anteroposterior Contraction of the Systemic Right Ventricle: Underrecognized Component of the Global Systolic Function

Accurate echocardiographic evaluation of the systemic right ventricle is challenging because of its specific morphology and contraction patterns. We present a detailed multimodality assessment of the systemic right ventricle, analyze the relative contribution of the longitudinal, radial, and anteroposterior components of systolic function, and identify reasons for a potential discrepancy among imaging modalities. (Level of Difficulty: Intermediate.)
