Assessment of Biventricular Myocardial Function with 2-Dimensional Strain and Conventional Echocardiographic Parameters: A Comparative Analysis in Healthy Infants and Patients with Severe and Critical Pulmonary Stenosis.

The interaction effect (group × medial location) on LV strain values had a marginal significance ( p for interaction = 0.053), with the estimated marginal means showing a tendency towards having the greatest value of strain from the basal-to-LV medial region in PS patients when compared to controls (−18.86, 95% CI: (−27.81, −9.91) for PS group vs. −12.13, 95% CI: (−16.51, −7.74) for controls).
