Conclusion
In conclusion, our data verify that RV systolic function is decreased in
patients with severe and very severe MS. TDI and VVI echocardiographic
features such as S’, TAPSE, RVFWS, and FAC are useful predictors of RV
dysfunction. We advise regular echocardiographic measurements for MS
patients in order to ensure early detection of RV dysfunction
predictors. If impairments in these parameters were recognized early in
the course of the disease, timely interventions might be able to
prevent, decrease, or reverse the adverse effects of MS such as PH or RV
dysfunction and drastically improve the prognosis of MS patients.
Further studies with larger cohorts of mild, moderate, severe, and very
severe MS cases are necessary to establish the extent of RV systolic
dysfunction using various echocardiographic measurements.
