New two-dimensional global longitudinal strain and strain rate imaging for assessment of systemic right ventricular function

Objectives:

To determine the usefulness of new two-dimensional strain indices, based on speckle tracking imaging, for assessment of systemic right ventricular (RV) function after an atrial switch operation for transposition of the great arteries.

Design:

Cross-sectional study.

Setting:

Tertiary paediatric cardiac centre.

Methods:

26 patients, mean (SD) age 21.0 (3.6) years at 19.9 (3.2) years after an atrial...
