Abstract
<p style="text-align:justify"><strong>Introduction</strong>: Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare and distinct entity of pulmonary hypertension. Pulmonary endarterectomy (PE) is a potential curative strategy in this setting. However, it is a delicate procedure requiring significant expertise. There’s no data regarding pre-procedural imagiological data by CT scan and hemodynamical response after PE.</p> <p style="text-align:justify"><strong>Objective</strong>: We aimed to correlate data from imagiological evaluation by CT scan with hemodynamic improvements after pulmonary angioplasty.</p> <p style="text-align:justify">Methods: Retrospective single-center study of consecutive CTEPH patients with clinical that underwent PE. Demographic, clinical, laboratorial, imagiological and hemodynamic data were collected. For statistical analysis, Spearman correlation was used to continuous variables and Mann-Whitney test if the variables were categorical.</p> <p style="text-align:justify"><strong>Results</strong>: We included 24 patients with mean age of 59.7±12.9 years, 54.2% were female. The majority (87.5%) of patients were under specific vasodilatory therapy. The functional class at baseline was WHO II in 33% and WHO III in 67%. There was hemodynamic improvement after surgery, with changes in mean pulmonary artery pressure (mPAP) (49 (42-59) vs 26 (21,3- 46,3), p 0,001), right atrial pressure (RAP) (11,5 (10-16) vs 6 (4-11), p 0,002), cardiac output (CO) (3,6 (3,2-4,2) vs 10,0 (8-12), p 0,0001) and pulmonary vascular resistance (PVR) (11,0 (7,3-15,1) vs 4,2 (2,5-6,2), p 0,001). We found an association between right ventricle to left ventricle (RV/LV) basal diameters ratio and RV/LV areas ratio in axial view and a decrease in pulmonary vascular resistance (p 0.006), with a RV/LV basal diameters ratio cut-off >1.3 (AUC 0.848 p=0.013) being the best predictor (sensivity 100% and specifity 70.6%). We also found the same association with RV/LV basal diameters ratio and RV/LV areas ratio obtained in 4-chamber view (p=0.048 vs p=0.047). There was a strong correlation between the RV/LV diameter ratio measured on the standard axial view and in 4-chamber view (R 0,882 p=0.0001).</p> <p style="text-align:justify"><strong>Conclusions</strong>: In conclusion, we were able to prove that non invasive measurements in CT scan can predict a good outcome after PEA, particularly RV/LV basal diameters ratio with a cut-off of >1,3 as the best predictor for a significant decrease in PVR. Moreover, axial determinations were able to provide good correlations, being much less time consuming, when compared to the determinations obtained by 4-chamber view.</p>
