Cardiac Fiber Imaging with 3D Ultrasound and MR Diffusion Tensor Imaging
Published in Ayman El-Baz, Jasjit S. Suri, Cardiovascular Imaging and Image Analysis, 2018
Cardiac fiber orientations play important roles in determining both electrical and mechanical functions of the heart. Their abnormality causes cardiac dysfunction that may results in heart failure or sudden death. Thus, the estimation of fiber orientations will be valuable for the clinical diagnosis of cardiac diseases. Considering the wide application of ultrasound in cardiology, ultrasound-derived cardiac fiber orientations would provide useful information for the diagnosis of cardiac abnormality. In addition, when the fiber information is combined with electrophysiological modeling it might also play a key role in both surgical plans and ablation guidance for the treatment of ventricular tachycardia and ventricular arrhythmia. Thus, our proposed method and its future improvements will contribute to better understanding of cardiac physiology and also provide a tool for diagnosis of heart diseases and prediction of their treatments.

The aim to restore a normal cardiac physiology in patients with conduction system disease is still ongoing after 60 years of cardiac pacing, in a quest of truly physiologic stimulation that stems from suboptimal outcome, namely occurrence of symptomatic LV dysfunction/heart failure, in 12–20% patients despite maintenance of atrio-ventricular (AV) synchrony [3].
