The Right Ventricular Response to High Afterload: Comparison between Healthy Persons and Patients with Transposition of the Great Arteries: A 2D Strain Study

Abstract

Myocardial deformation parameters were significantly different in systemic and normal RV indicating a dependency of myocardial deformation parameters on right ventricular afterload. The use of myocardial deformation imaging identified a shift from longitudinal to circumferential contraction pattern in the systemic RV in comparison to the LV. This might demonstrate a response to the systemic load creating a myocardial hypertrophy.
