Echocardiography and Cardiac Magnetic Resonance-Based Feature Tracking in the Assessment of Myocardial Mechanics in Tetralogy of Fallot: An Intermodality Comparison.
We investigated intermodality agreements of strains from two-dimensional echocardiography (2 DE) and cardiac magnetic resonance ( CMR) feature tracking ( FT) in the assessment of right ( RV) and left ventricular ( LV) mechanics in tetralogy of Fallot ( TOF). Patients were prospectively studied with...

Patients were prospectively studied with 2 DE and CMR performed contiguously. LV and RV strains were computed separately using 2 DE and CMR- FT. Segmental and global longitudinal strains ( GLS) for the LV and RV were measured from four-chamber views; LV radial (global radial strain [ GRS]) and circumferential strains ( GCS) measured from short-axis views. Intermodality and interobserver agreements were examined. In 40 patients (20 TOF, mean age 23 years and 20 adult controls), LV, GCS showed narrowest intermodality limits of agreement (mean percentage error 9.5%), followed by GLS (16.4%). RV GLS had mean intermodality difference of 25.7%. GLS and GCS had acceptable interobserver agreement for the LV and RV with both 2 DE and CMR- FT, whereas GRS had high interobserver and intermodality variability. In conclusion, myocardial strains for the RV and LV derived using currently available 2 DE and CMR- FT software are subject to considerable intermodality variability. For both modalities, LV GCS, LV GLS, and RV GLS are reproducible enough to warrant further investigation of incremental clinical merit. pubtype: Academic Journal doctype: diagnostic images research tables/charts tracings Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
