Background: The aim of the study was to assess soluble ST2 (sST2) concentration and its dynamic changes in the periprocedural period in patients with chronic thromboembolic pulmonary hypertension (CTEPH) treated with balloon pulmonary angioplasty (BPA). Methods: We prospectively analyzed 57 procedures of BPA performed in 37 patients with CTEPH. Biomarkers, such as N-terminal pro B-type natriuretic peptide (NT-proBNP), troponin T (TnT), and sST2 were assessed at four time points: Before the BPA procedure, 24 h and 48 h after the procedure, and at the discharge from hospital. Each postprocedural period was assessed for complications. Results: Before the BPA procedure, median sST2 concentration was 26.56 ng/mL (IQR: 16.66–40.83 ng/mL). sST2 concentration was significantly higher 24 h and 48 h after the BPA compared to the baseline measurements (33.31 ng/mL (IQR: 20.81–62.56), p = 0.000 and 27.45 ng/mL (IQR: 17.66–54.45), p = 0.028, respectively). sST2 level 24 h after the BPA procedure was significantly higher in the group with complications compared to the group without complications in the postprocedural period (97.66 ng/mL (IQR: 53.07–126.18) vs. 26.86 ng/mL (IQR: 19.10–40.12), p = 0.000). Conclusions: sST2 concentration in patients with CTEPH treated with BPA changes significantly in the postprocedural period and is significantly higher in the group with complications in postprocedural period.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Chronic thromboembolic pulmonary hypertension (CTEPH) leads to a progressive increase in pulmonary vascular resistance (PVR) and pulmonary artery pressure (PAP) with the development of severe dysfunction of the right heart and heart failure. Mortality for three years with an average pressure in the pulmonary artery (PA) of more than 50 mmHg is more than 90%. Balloon pulmonary angioplasty (BPA) has a significant advantage over other methods of surgical treatment, but it requires the determination of additional non-invasive markers of effectiveness. Transthoracic echocardiography (TTE) remains the main method for assessing the morphology and function of the heart. Purpose Compare different indicators reflecting the severity of CTEPH with TTE indicators before and after BPA. To evaluate the effectiveness of using BPA for the treatment of patients with CTEPH using routine TTE and speckle tracking mode. Materials and methods For 18 months 30 patients without concomitant cardiovascular pathology were subjected to several BPA sessions. Before treatment, 50% of patients belonged to the 3 CTEPH functional class (FC), 40% to 2 FC, 10% to 1 FC. The average number of sessions was 4.7 ± 1.3. Before the first BPA and after the last, all the patients were performed: six-minute walk test (6MWT, metres), Borg scale (in points), test for NT-proBNP (pg/ml); TTE with assessment of the right ventricle (RV) and left ventricle (LV) including areas of the right atrium (aRA, cm2), mean pulmonary artery pressure (PUPM,mmHg),RV free wall strain (GLSFW, %), RV free wall strain rate (GLSRFW, sm/sec), RV free wall postsystolic shortening (PSSFW, %), tricuspid annular plane systolic excursion (TAPSE, sm), tricuspid annulus systolic velocity (TASV, sm/sec). Results. Before the first BPA session, the 6MWT in the patient group averaged 315.9 ± 9.08 metres, after - 439.5 ± 11.45 m; the Borg from 5.4 ± 0.94 points decreased to 4 ± 1.01 points; NT-proBNP before the treatment was 1513 ± 13.01 pg/ml, after - 171 ± 6.09; according to TTE the ratio of RV/ LV before and after treatment was 1.31 ± 0.02 and 0.97 ± 0.04; aRA was 29.3 ± 4.87 and 22.3 ± 3.53 cm2; basal RV - 52 ± 5.11 and 44 ± 7.26 mm; PUPM decreased from 76.6 ± 7.65 to 31.3 ± 3.78 mmHg; GLSFW from -14.69 ± 2.33 came to 17.5 ± 3.45 %; GLSRFW with -0.9 ± 0.09 to -1.7 ± 0.11 cm/sec; TAPSE from 16.7 ± 1.87 to 18.2 ± 2.34 cm; TASV from 10.11 ± 1.45 to 12.25 ± 1.98 cm/s, PSSFW before treatment was -18.4 ± 1.2%, after treatment in 66% of patients disappeared, in 34% became an average of 17.4 ± 0.9% The distribution of STEPH FC has also changed. Conclusion. BPA leads to an improvement in the tolerance of physical activity, clinical indicators, and parameters of central hemodynamics in the pulmonary circulation, evaluated according to direct manometry, and leads to reverse remodeling of the RV in the long term. Performing a staged BPA leads to an improvement in the functional parameters of contractility of the RV.

Introduction: Conventionally, angiographic classification has been used for chronic thromboembolic pulmonary hypertension (CTEPH). However, a classification based on lesion morphology is needed in the era of balloon pulmonary angioplasty (BPA). We sought to propose a classification of CTEPH based on lesion morphology detected by optical coherence tomography (OCT) and to evaluate its association with physiological stenosis assessed with a pressure wire and therapeutic efficacy in BPA. Methods: We analyzed 43 lesions in 17 patients who were treated with BPA under OCT and pressure-wire guidance from November 2012 to March 2015. OCT findings were classified into the following 4 categories: 1) mono-hole, 2) septum, 3) multi-hole with thin wall, and 4) multi-hole with thick wall. Results: Angiographic findings did not match the specific morphologic classification based on OCT findings. At the pre-BPA assessment, the pressure ratio of the septum type was significantly higher than that of the mono-hole and multi-hole with thick wall types (p = 0.026 and 0.047, respectively). Under the OCT-based classification, more than 50% of the septum and multi-hole with thin wall types could accomplish >0.8 of the mean pressure ratio assessed by a pressure wire, and these proportions were significantly higher than those of the other 2 types: mono-hole and multi-hole with thick wall (p = 0.044). Based on angiographic classification, accomplishment of this criterion was not significantly different among angiographic types. Conclusions: OCT-based morphologic lesion classifications in CTEPH were useful to predict whether the lesion stenosis could improve to the acceptable level mediated by BPA.

Abstract Introduction Pulmonary endarterectomy leads to a decrease in systemic inflammation and improvement in endothelial function in patients with chronic thromboembolic pulmonary hypertension (CTEPH). Balloon pulmonary angioplasty (BPA) improves pulmonary hemodynamics in patients with inoperable CTEPH. Aim To assess changes in systemic inflammation and endothelial dysfunction after a single BPA session and after completion of the treatment. Methods We enrolled consecutive, inoperable CTEPH patients who underwent BPA. Interleukin 6, 10 (IL-6, IL-10), and C-reactive protein (hsCRP) constituted markers of systemic inflammation. Endothelin-1 (ET-1) served as a marker of endothelial dysfunction. Serum concentration of selected markers was assessed in every patient before, 24 hours after the first BPA session and 6 months after completion of the BPA treatment. Age- and sex-matched healthy subjects served as a control group. Results We recruited 20 patients with inoperable CTEPH (6 males [30%]), aged 67 [61–74] years in New York Heart Association class III (n=19 [95%]) and II (n=1 [5%]). BPA treatment was completed with a median of 5 [2–8] BPA sessions per patient. Before starting the treatment CTEPH patients, as compared to controls (n=10), had raised serum level of IL-6 (3.82 [2.75 - 6.03] vs. 2.64 [0.88 - 4.75] pg/ml; p=0.04), hsCRP (2.47 [0.93 - 4.27] vs. 1.23 [0.48–3.21] ng/ml; p=0.02) and ET-1 (2.68 [2.24 - 3.64] vs. 1.47 [1.4 - 1.82] pg/ml; p=0.004). There was no difference in IL-10 level. 24 hours after a BPA session we observed an increased level of IL-6, IL-10 and hsCRP. (Tab.) 6 months after completion of the BPA treatment there was a reduced level of IL-6, hsCRP and ET-1 (Tab.) Table 1. Changes (Δ) in serum concentration of analyzed markers 24 hours after a single BPA session and at 6-months assessment after completion of the BPA treatment (n=20) Initial Δ at 24 hours after single BPA p Δ at 6-months follow-up p ET-1 [pg/ml] 2.68 [2.24; 3.64] −0.2 [−0.5; 0.23] 0.21 −0.47 [−0.96; 0.05] 0.004 IL-6 [pg/ml] 3.82 [2.75; 6.03] 3.67 [1.41; 7.16] 0.008 −0.82 [−3.11; 0.54] 0.04 IL-10 [pg/ml] 0.53 [0.44; 0.58] 0.32 [0.21; 0.87] 0.006 −0.11 [−0.33; 0.14] 0.94 hsCRP [ng/ml] 2.47 [0.93; 4.27] 5.4 [3.96; 10.59] 0.008 −0.36 [−0.94; 0.16] 0.02 ET-1, endothelin 1; hsCRP, C-reactive protein; IL-6, interleukin 6; IL-10, interleukin 10. Conclusions Patients with inoperable CTEPH, as compared to healthy controls, exhibit an increased systemic inflammation and endothelial dysfunction, which both improve after completion of the BPA treatment. At short-term follow-up after single BPA session there is an increase in systemic inflammatory response.
