In this article, we present the case of a 38-year-old female who suffered from serious respiratory distress. After an extensive pulmonary artery imaging diagnostic work-up (CTPA, MRA and PET), we were unable to differentiate between chronic thromboembolic pulmonary hypertension (CTEPH) vs. pulmonary artery sarcoma (PAS) due to extensive filling defects and extraluminal findings. Although surgery was postponed for nine months due to the COVID-19 pandemic, CTEPH diagnosis, due to a high-thrombus burden, was finally confirmed after pulmonary endarterectomy (PEA). Conclusively, imaging findings of rare cases of CTEPH might mimic PAS and the surgical removal of the lesion are both needed for a final diagnosis. What is Already Known about This Topic? Pulmonary artery sarcoma (PAS) is a rare but aggressive malignancy, which originates from the intimal layer of the pulmonary artery (PA); Chronic thromboembolic pulmonary hypertension (CTEPH) is based on chronic, organized flow-limiting thrombi inside PA circulation and subsequent pulmonary hypertension. What Does This Study Contribute? Since radiological findings of CTEPH cases might rarely mimic PAS, pulmonary artery endarterectomy and subsequent histopathologic study are needed for a final diagnosis.

Balloon pulmonary angioplasty (BPA) is an emerging treatment for patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH).We report on a prospective series of 56 consecutive patients who underwent 266 BPA interventions (median, five per patient) at two German institutions. All patients underwent a comprehensive diagnostic work-up including right heart catheterisation at baseline and 24 weeks after their last intervention.BPA resulted in improvements in WHO functional class, 6 min walk distance (mean change, +33 m), right ventricular function and haemodynamics, including a decline in mean pulmonary artery pressure by 18% and in pulmonary vascular resistance by 26%. Procedure-related adverse events occurred in 9.4% of the interventions. The most common complications were related to pulmonary vascular injury and consecutive pulmonary bleeding. Most of these events were asymptomatic and self-limiting, but one patient died from pulmonary bleeding, resulting in a mortality rate of 1.8%.BPA resulted in haemodynamic and clinical improvements but was also associated with a considerable number of complications, including one fatal pulmonary bleeding. As the effects of BPA on survival are unknown, randomised controlled outcome trials comparing BPA with approved medical therapies in patients with inoperable CTEPH are required to allow for appropriate risk–benefit assessments.

Wedge Pressure

Chronic thromboembolic pulmonary hypertension (CTEPH) is defined as a mean pulmonary artery pressure ≥25 mm Hg and pulmonary artery wedge pressure ≤15 mm Hg in the presence of occlusive thrombi within the pulmonary arteries. Surgical pulmonary thromboendarterectomy (PTE) is considered the best treatment option for CTEPH.

Abstract Background In chronic thromboembolic pulmonary hypertension (CTEPH), pulmonary artery obstruction leads to impaired pulmonary hemodynamics and secondary right heart failure, which is highly predictive of outcome. Thus, the extent of myocardial -especially right heart- remodelling is an indicator of disease severity. Purpose The aim of the present study was to assess growth differentiation factor-15 (GDF-15), galectin-3, and suppression of tumorigenicity 2 (ST2) as non-invasive biomarkers of myocardial remodelling in patients suffering from CTEPH. Methods We analysed the serum levels of GDF-15, galectin-3 and ST2 in a cohort of 64 CTEPH patients and in a control group of 25 patients without cardiovascular disease. The biomarker levels were further correlated with clinical, laboratory, and hemodynamic data, including 6-minute walking distance (6-MWD), N-terminal pro-brain natriuretic peptide (NT-proBNP), mean pulmonary artery pressure (meanPAP), pulmonary vascular resistance (PVR), and right atrial pressure (RAP). Results The biomarker levels in the control group were: galectin-3: 3.5 ng/l (IQR 2.7–4.0), GDF-15: 92.6 pg/ml (IQR 78.5–129.1), and ST2: 48.65 ng/l (IQR 35.5–57.0). CTEPH patients had higher levels of GDF-15 (196.7 pg/ml; IQR 128.4–302.8; p<0.001) and ST2 (52.6 ng/l; IQR 44.5–71.9; p=0.05) but not galectin-3 (3.4 ng/l; IQR 2.7–4.3; p=0.84). In the CTEPH cohort, patients with a meanPAP >35 mmHg (GDF-15: p=0.01; ST2: p=0.04) and patients with a PVR >500 dyn sec cm–5 (GDF-15: p=0.004; ST2: p=0.002) had significantly increased biomarker levels. For the detection of a meanPAP >35mmHg, ROC analysis revealed an AUC of 0.71 for GDF-15 and 0.67 for ST2. The level of GDF-15 correlated with the level of NT-proBNP (rrs=0.69; p≤0.001) and the RAP (rrs=0.54; p≤0.001) and inversely with the 6-MWD (rrs=−0.47; p≤0.001). The level of ST2 correlated with the level of NT-proBNP (rrs=0.67; p≤0.001) and the RAP (rrs=0.54; p≤0.001) and inversely with the 6-MWD (rrs=-0.31; p=0.02). Conclusion Our results demonstrate that GDF-15 and ST2, non-invasive biomarkers of myocardial remodelling, are significantly elevated in patients suffering from CTEPH. The correlation of biomarker levels with established outcome predictors suggests a use as indicators of disease severity.
