Global Longitudinal Strain Right Ventricle (GLS RV) as a Predictor for Mean Pulmonary Artery Pressure (MPAP) on Secundum Atrial Septal Defect (ASD) with Pulmonary Hypertension.

Objectives: The objectives of the study were to determine the association between global longitudinal strain right ventricle (GLS-RV) and mean pulmonary artery pressure (mPAP) on secundum atrial septal defect (ASD) with pulmonary hypertension (PH).

Methods: This study was an analytic observational with the cross-sectional approach. This study was conducted with secundum ASD patients who underwent right heart catheterization (RHC) from February 2019 to July 2019 at Sardjito General Teaching Hospital Yogyakarta. Demographic data were collected and echocardiographic parameters were evaluated based on the standard examination. The results were statistically analyzed using the correlation hypothesis test. If the data were normally distributed, the Pearson's correlation test was used, if the data were not normally distributed, Spearman's correlation test was used to analyze the correlation.

Results: Thirty-four patients were enrolled in this study. There was strongly significant positive correlation between GLS-RV and mPAP found in patients with Secundum ASD (P = 0.0001, r = 90.5%).

Conclusions: This is the first study in Indonesia that analyzed the association between GLS-RV and mPAP in Secundum ASD patients. There was a strongly significant positive correlation between GLS-RV and mPAP in patients with Secundum ASD after RHC. We assume that the association is influenced by progressivity and degree of disease severity.
