Left ventricular blood flow characteristics in children with premature ventricular contractions by 4D flow CMR
Motivation: A novel imaging method was developed to diagnose children with premature ventricular contractions (PVCs), thereby preventing heart failure or cardiomyopathy. Goal(s): To determine the changes in the blood flow composition of LV in children with PVCs, a free breathing 4D flow CMR was performed. The relationship of PVC load with LV function was explored. Approach: The children with PVCs underwent 24-hour dynamic ECG and CMR examination within 3 days. Thus, we determined their cardiac function and hemodynamic parameters. Results: Children with PVCs had reduced direct blood flow in LV, which showed a significant negative correlation with PVC load. Impact: In this study, we analyzed the characteristics of the left ventricular blood flow in children with premature ventricular contractions (PVCs). Thereafter, we elucidated the pathophysiological mechanism of PVCs, which provided the basis for clinical treatment and prognostic evaluation.
