Abstract

Recent years have witnessed exponential growth in cardiac imaging technologies, allowing better visualization of complex cardiac anatomy and improved assessment of physiology. These advances have become increasingly important as more complex surgical and catheter-based procedures are evolving to address the needs of a growing congenital heart disease population. This state-of-the-art review presents advances in echocardiography, cardiac magnetic resonance, cardiac computed tomography, invasive angiography, 3-dimensional modeling, and digital twin technology. The paper also highlights the integration of artificial intelligence with imaging technology. While some techniques are in their infancy and need further refinement, others have found their way into clinical workflow at well-resourced centers. Studies to evaluate the clinical value and cost-effectiveness of these techniques are needed. For techniques that enhance the value of care for congenital heart disease patients, resources will need to be allocated for education and training to promote widespread implementation.

Abstract

Background: A previous multicenter study showed that longitudinal changes in standard cardiac functional parameters were associated with the development of cardiomyopathy in childhood cancer survivors (CCS). Evaluation of the relationship between global longitudinal strain (GLS) changes and cardiomyopathy risk was limited, largely due to lack of quality apical 2‐ and 3‐chamber views in addition to 4‐chamber view. We sought to determine whether apical 4‐chamber longitudinal strain (A4LS) alone can serve as a suitable surrogate for GLS in this population. Methods: A4LS and GLS were measured in echocardiograms with acceptable apical 2‐, 3‐, and 4‐chamber views. Correlation was evaluated using Pearson and Spearman coefficients, and agreement was evaluated with Bland–Altman plots. The ability of A4LS to identify normal and abnormal values compared to GLS as the reference was evaluated. Results: Among a total of 632 reviewed echocardiograms, we identified 130 echocardiograms from 56 patients with adequate views (38% female; mean age at cancer diagnosis 8.3 years; mean follow‐up 9.4 years). Correlation coefficients between A4LS and GLS were.89 (Pearson) and.85 (Spearman), with Bland–Altman plot of GLS—A4LS showing a mean difference of −.71 ± 1.8. Compared with GLS as the gold standard, A4LS had a sensitivity of 86% (95% CI 79%–93%) and specificity of 82% (69%–95%) when using normal range cutoffs and 90% (82%–97%) and 70% (58%–81%) when using ±2 standard deviations. Conclusion: A4LS performs well when compared with GLS in this population. Given the more recent adoption of apical 2‐ and 3‐chamber views in most pediatric echocardiography laboratories, A4LS is a reasonable stand‐alone measurement in retrospective analyses of older study cohorts and echocardiogram biorepositories.

Abstract

Background: Elevated left ventricular outflow tract (LVOT) gradients during exercise can occur in patients with hypertrophic cardiomyopathy (HCM) as well as in athletes and normal controls. The authors' staged exercise protocol calls for imaging at rest and during each stage of exercise to evaluate the mechanism of LVOT obstruction at each stage. They investigated whether this staged approach helps differentiate HCM from athletes and normal controls. Methods: They reviewed pediatric exercise stress echocardiograms completed between January 2009 and October 2017 at their center and identified those with gene-positive HCM, athlete's heart, and normal controls. Children with inducible obstruction (those with no LVOT gradient at rest who developed a LVOT peak gradient > 25 mm Hg during exercise) were included. LVOT peak gradient, velocity time integral, acceleration time, and deceleration time were measured at rest, submaximal stages, and peak exercise. Results: Compared with athletes, HCM patients had significantly higher LVOT peak gradients at rest (P = .019), stage 1 of exercise (P = .002), and peak exercise (P = .051), as well as a significantly higher change in LVOT peak gradient from rest to stage 1 (P=.016) and from rest to peak (P = .038). The acceleration time/deceleration time ratio of the LVOT Doppler was significantly lower in HCM patients compared with normal controls at peak exercise. Conclusions: The HCM patients who develop elevated LVOT gradients at peak exercise typically manifest early obstruction in the submaximal stages of exercise, which helps to differentiate them from athletes and normal controls.
