Abstract Background: Although Doppler echocardiography is routinely used to assess left
ventricle cardiac output, there are limited data about the feasibility of Doppler echo‐
cardiography for right ventricular (RV) cardiac output assessment in patients with
left‐to‐right shunt. The purpose of the study was to determine the correlation be‐
tween Doppler‐derived and Fick‐derived RV cardiac index (CI), and the interobserver
correlation in Doppler‐derived RV CI assessment.
Methods: Retrospective study of patients (age ≥18 years) with unrepaired atrial septal
defect who underwent cardiac catheterization and echocardiography (within 3 days),
2004‐2017. RV CI was calculated using the hydraulic orifice formula: [.785… More >
