Can imaging heart muscle strain help manage pediatric heart disease better?
Imaging heart muscle strain is a sensitive, non-invasive technique that measures how the heart muscle deforms during contraction and relaxation. In children with congenital heart disease, standard tests like ejection fraction often miss early signs of heart muscle problems. Strain imaging, especially using speckle-tracking echocardiography, can detect subtle dysfunction earlier, monitor how well treatments work, and help predict long-term outcomes. A 2025 narrative review of 40 studies confirms its clinical utility across many types of congenital heart disease 4.
What the research says
A 2025 narrative review found that strain imaging is useful for detecting early myocardial dysfunction, monitoring surgical outcomes, and predicting prognosis in various congenital heart diseases, including atrial and ventricular septal defects, Tetralogy of Fallot, single-ventricle physiology, and transposition of the great arteries 4. Right ventricular longitudinal strain and atrial strain showed prognostic value 4. This technique can identify problems before standard measures like ejection fraction change 4. Another study from 2007 noted that traditional pump indices like ejection fraction depend on loading conditions and heart rate, making them less reliable, while newer echocardiographic indices better reflect intrinsic myocardial contractility 9. A 2022 study using cardiac magnetic resonance feature-tracking in patients with Ebstein's anomaly (a rare congenital heart disease) found significantly impaired right ventricular strain compared to healthy controls, showing that strain imaging can detect early signs of systolic impairment even before surgery 10. While these sources focus on strain imaging, other research on congenital heart disease management highlights the importance of risk stratification and monitoring: a retrospective study linked congenital heart surgery to cerebral desaturation events in infants 1, and another study associated higher red cell distribution width-to-albumin ratio with increased in-hospital mortality 2. Machine learning applications are also being explored to improve detection and management 3. However, strain imaging directly addresses the question of better management by providing earlier and more detailed information about heart muscle function.
What to ask your doctor
- Could speckle-tracking echocardiography (strain imaging) help detect early heart muscle problems in my child's specific type of congenital heart disease?
- How does strain imaging compare to standard echocardiography for monitoring my child's heart function over time?
- Are there any risks or limitations of strain imaging that I should be aware of?
- Would strain imaging be useful before or after my child's planned heart surgery to guide treatment decisions?
- Is strain imaging available at your center, and if not, where could we get it done?
