Abstract
SANZ-PASCUAL, Elena et al. Speckle-tracking echocardiography and MCR-feature tracking in Fontan circulation. Differences between right and left ventricles. Rev. Colomb. Cardiol. [online]. 2022, vol.29, n.4, pp.412-420. Epub Nov 08, 2022. ISSN 0120-5633. https://doi.org/10.24875/rccar.21000009.
Introduction:
In patients with TCPC, the development of ventricular dysfunction is inevitable and is more precocious in SRVs. Myocardial deformation by STE and CMR-FT is promising.
Objective:
To analize ventricular function in patients with TCPC using STE and CMR-FT compared with conventional cMRI, depending on SV morphology, to determine their role in early diagnosis of ventricular dysfunction.
Method:
Sixty-four patients with TCPC were included. Longitudinal and circumferential strain by STE and CMR-FT and ventricular volume and EF were obtained.
Results:
Dysfunction analyzed by cMRI showed no association with ventricular morphology. SRVs had lower values in STE and CMR-FT compared with SLVs, with similar EF. While not equivalent, correlation was observed between the STE and the CMR-FT values, demonstrating good feasibility and reproducibility.
Conclusion:
The strain data in CMR-FT and STE could be useful for diagnosis and monitoring of ventricular function and as markers of early SRV dysfunction with preserved EF.
