Coupling estimation by Cardiac MRI as a potential biomarker in
patients with repaired Tetralogy of Fallot
T. Shimfessel, M. Gusseva, A. Tandon, A. Valente, T. Geva,
A. Marenco, P. Beerbaum, T. Pickardt, S. Sarikouch, R.
Chabiniok, G. Greil, T. Hussain
University of Texas Southwestern Medical Center, Dallas, United States
Impact: CMR-derived Ventriculo-Arterial Coupling (VAC)
ratio accurately reflects the invasively derived VAC and may
be used as an indicator for possible future cardiac events
and therefore improve risk stratification in patients with
repaired Tetralogy of Fallot.

3679. Subdivided
High-resolution Angiography with Reconstruction of Exchanged
Data (SHARED)
D. Lichthardt, M. Schmidt, J. Wetzl, A. Nagel, D. Giese
Friedrich-Alexander-University Erlangen-Nürnberg, Erlangen, Germany
Impact: Multiple breath-held scans with predictable
timings yield high-resolution angiography images. The first
scan is used for automatic view planning and, unlike
dedicated localizers, contributes to diagnostic images.
Online reconstruction after each breath-hold enables
increasing spatial resolution with every breath-hold.

3681. Cardiac
Motion-Resolved 3D Whole-Heart Myocardial T2* Mapping Reveals
Diminished Cyclic Response in Hypertrophic Cardiomyopathy at
1.5T
Y. Huang, C-H Yun, X. Guan, L-T Huang, S. Shalikar, F.
Rader, M. Ahmed ZakiAl-Ani, J. Wei, A. Kwan, C. Nguyen, X.
Bi, D. Li, T. Niendorf, M-C Ku, R. Dharmakumar, H-J Yang
Indiana University School of Medicine , Indianapolis, United States
Impact: This study applied a free-breathing,
cardiac-phase-resolved whole-heart T2* mapping technique for
assessing T2*variations across the cardiac cycle. Although
additional validation is needed, our early findings
demonstrate the approach's potential to assess changes in
myocardial oxygenation impairments associated with
hypertrophic cardiomyopathy.
