PG - 2050-2056 LID - 10.1111/echo.14503 [doi] AB - PURPOSE: Right ventricular (RV) function is an important factor in the prognosis of chronic thromboembolic pulmonary hypertension (CTEPH) in patients. In our study, we aimed to evaluate the timing and magnitude of regional RV function before and after balloon pulmonary angioplasty (BPA) using speckle tracking echocardiography (STE) and their relation to clinical and hemodynamic parameters in patients with CTEPH. MATERIAL AND METHOD: We enrolled 20 CTEPH patients and 19 healthy subjects in our study. Enrolled patients underwent echocardiography, right heart catheterization (RHC), and 6-minute walk distance (6MWD) test at baseline and after the BPA. RESULTS: In hemodynamic RHC measurements and clinical evaluations, mean pulmonary artery pressure (median: 53.5 mm Hg vs 37.0 mm Hg, P = .001) and pulmonary vascular resistance (median: 12 Wood units [WU] vs 7 WU, P = .001) and pro-brain natriuretic peptide level decreased and 6MWD increased after BPA sessions. There was no statistically significant difference between before and after the BPA sessions in conventional echocardiographic measurements. In STE analysis, the electromechanical delay (EMD) between RV free wall (RVF) and LV lateral wall (LVL) (median: 65 ms vs 47.5 ms, P = .01) and RV peak systolic strain dispersion index (52 ms vs 29 ms, P = .001) were higher in patients with CTEPH than healthy controls before the BPA. Both these parameters decreased significantly after BPA. CONCLUSION: Chronic thromboembolic pulmonary hypertension was associated with RV electromechanical delay and dispersion based on the STE analysis. Balloon pulmonary angioplasty might have an important impact on the improvement of both RV function and hemodynamics. CI - (c) 2019 Wiley Periodicals, Inc.
