ABSTRACT

OBJECTIVE:

The aim of the study was to evaluate the early myocardial dysfunction detected by strain echocardiography in children with multisystem inflammatory syndrome related to SARS-CoV-2 infection.

METHODS:

This cross-sectional study was conducted with 47 patients diagnosed with MIS-C and 32 healthy age- and gender-matched children. All patients underwent two-dimensional, colour, pulsed, and tissue Doppler, and 2D speckle tracking echocardiography examination at admission, 2 weeks, and 2 months after discharge. The MIS-C patient group was compared with the control group. Echocardiographic changes in MIS-C patients during follow-up were evaluated.

RESULTS:

Of 47 patients, 30 (63.8%) were male and 17 (36.2%) were female. The mean age at diagnosis was 9.1 ± 4.3 (1.25-17) years. At admission, 25 patients had abnormal findings on conventional echocardiography. Among them, eight patients had left ventricular systolic dysfunction. Ejection fraction and fractional shortening were significantly lower in the patient group at admission compared to controls (p = 0.013, p = 0.010, respectively). While the ejection fraction was <55% in eight patients, and global longitudinal strain was lower than -2SD in 29 patients at admission. Global longitudinal strain z-score <-2SD persisted in 13 patients at 2-month follow-up. Ejection fraction increased above 55% in 3.42 ± 0.53 days in 7 of 8 patients with left ventricular systolic dysfunction, ejection fraction was 51% at discharge in one patient, and left ventricular systolic dysfunction persisted at the 6-month of follow-up.

CONCLUSION:

These results confirmed that speckle tracking echocardiography is more likely to detect subclinical myocardial damage compared to conventional echocardiography. In addition, it is a valuable method for follow-up in this patient group.
