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.
