Abstract
Methods We studied 15 pts with TOF (6 mon-45 y) post repair, 15 pts with ASD, VSD and CO (5 y-37 y) and 8 healthy adults (24-35 y). MR images were acquired with an ECG gated 1.5/3 T Magnet with segmented gradient-echo cine-loop sequences (short/long/rotated axis) to cover the entire RV and LV. Images were analyzed offline by VVI (Siemens). RV size and function was correlated for each patient). LV myocardial strain, direction of twist and untwisting, time to peak twist and length to peak diastolic untwisting were measured and compared for each patient.
Highlights
In patients with CHD (CO, ASD, VSD and ToF) satisfactory post-op outcome is not solely dependent on systolic RV and LV function
Diastolic untwisting is altered in patients with congenital heart disease: a novel MR speckle tracking method for cine-MRI
