Abstract
Methods 28 Fontan subjects (median age 16.6 years, 14/28 morphologic left ventricle, 14/28 morphologic right ventricle) underwent a resting and exercise CMR. Standard high resolution, segmented balanced steady state free precession (SSFP) images were acquired with breath holds at rest. Cartesian real time (RT) cine images were acquired at rest then repeated at exercise, targeting the HR at anaerobic threshold on a recent metabolic exercise stress test (EST). Ventricular volumes and cardiac output were calculated offline. Off-line strain analysis was performed (TomTec 2D CPA, v. 1.0) on the “4-chamber” and shortaxis views at basal, mid, and apical levels.
