Abstract
BACKGROUND Among patients with pulmonary arterial hypertension (PAH), acute vasoreactivity testing during right heart catheterization may identify acute vasoresponders, for whom treatment with high-dose calcium channel blockers (CCBs) is recommended. However, long-term outcomes in the current era remain largely unknown. We sought to evaluate the implications of acute vasoreactivity response for long-term response to CCBs and other outcomes. METHODS Patients diagnosed with PAH between January 1999 and December 2018 at 15 pulmonary hypertension centers were included and analyzed retrospectively. In accordance with current guidelines, acute vasoreactivity response was defined by a decrease of mean pulmonary artery pressure by ≥10 mm Hg to reach <40 mm Hg, without a decrease in cardiac output. Long-term response to CCBs was defined as alive with unchanged initial CCB therapy with or without other initial PAH therapy and World Health Organization functional class I/II and/or low European Society of Cardiology/European Respiratory Society risk status at 12 months after initiation of CCBs. Patients were followed for up to 5 years; clinical measures, outcome, and subsequent treatment patterns were captured. RESULTS Of 3702 patients undergoing right heart catheterization for PAH diagnosis, 2051 had idiopathic, heritable, or drug-induced PAH, of whom 1904 (92.8%) underwent acute vasoreactivity testing. A total of 162 patients fulfilled acute vasoreactivity response criteria and received an initial CCB alone (n=123) or in combination with another PAH therapy (n=39). The median follow-up time was 60.0 months (interquartile range, 30.8-60.0), during which overall survival was 86.7%. At 12 months, 53.2% remained on CCB monotherapy, 14.7% on initial CCB plus another initial PAH therapy, and the remaining patients had the CCB withdrawn and/or PAH therapy added. CCB long-term response was found in 54.3% of patients. Five-year survival was 98.5% in long-term responders versus 73.0% in nonresponders. In addition to established vasodilator responder criteria, pulmonary artery compliance at acute vasoreactivity testing, low risk status and NT-proBNP (N-terminal pro-B-type natriuretic peptide) levels at early follow-up correlated with long-term response and predicted survival. CONCLUSIONS Our data display heterogeneity within the group of vasoresponders, with a large subset failing to show a sustained satisfactory clinical response to CCBs. This highlights the necessity for comprehensive reassessment during early follow-up. The use of pulmonary artery compliance in addition to current measures may better identify those likely to have a good long-term response.

Abstract
BACKGROUND While computed tomography pulmonary angiography (CTPA) is an integral part of the work-up in patients with suspected pulmonary hypertension (PH), there is no established CTPA-derived prognostic marker. We aimed to assess whether quantitative readouts of lung vessel morphology correlate with established prognostic indicators in PH. METHODS We applied a fully-automatic in-house developed algorithm for segmentation of arteries and veins to determine lung vessel morphology in patients with precapillary PH who underwent right heart catheterization and CTPA between May 2016 and May 2019. Primary endpoint of this retrospective study was the calculation of receiver operating characteristics for identifying low and high mortality risk according to the 3-strata risk assessment model presented in the current guidelines. RESULTS We analyzed 73 patients, median age 65 years (interquartile range (IQR): 54-76), female/male ratio 35/38, median mean pulmonary arterial pressure 37 mm Hg (IQR: 30-46), and found significant correlations with important prognostic factors in pulmonary arterial hypertension. N-terminal pro-brain natriuretic peptide, cardiac index, mixed venous oxygen saturation, and 6-minute walking distance were correlated with the ratio of the number of arteries over veins with vessel diameters of 6-10 mm (Spearman correlation coefficients ρ = 0.64, p < 0.001; ρ = -0.60, p < 0.001; ρ = -0.47, p = 0.005; ρ = -0.45, p = 0.001, respectively). This ratio predicted a low- and high-risk score with an area under the curve of 0.73 (95% confidence interval (CI): 0.56-0.90) and 0.86 (95% CI: 0.74-0.97), respectively. CONCLUSIONS The ratio of the number of arteries over veins with diameters between 6 and 10 mm is significantly correlated with prognostic markers in pulmonary hypertension and predicts low and high mortality risk.

Abstract
Patients with left heart disease (LHD) often display pulmonary hypertension (PH), which impacts morbidity and mortality. The pathophysiology of PH is complex and entails pulmonary congestion due to elevated left-sided filling pressures, pulmonary vasoconstriction as well as vascular remodeling. The recent ESC/ERS Guidelines on pulmonary hypertension updated the hemodynamic definitions of pulmonary hypertension in general, and the subclassification of post-capillary PH. This review summarizes recent advances in the diagnostic work-up and management strategies of PH associated with LHD. Specifically, we summarize revisited hemodynamic definitions and the characteristics of isolated post-capillary PH (IpcPH) and combined post- and pre-capillary PH (CpcPH). Furthermore, we review the current knowledge on the pathogenesis of PH-LHD, the prognostic relevance of hemodynamic parameters, and the management strategies, differentiating between treatment of the underlying left heart disease and therapies targeting the pulmonary circulation. The article emphasises the need for precise diagnostic work-up and individualized treatment strategies in patients with PH-LHD.

Abstract
In patients with pulmonary hypertension (PH) or with other pulmonary or cardiac diseases, the 6-minute walking test – accompanied by the Borg dyspnea score – is frequently utilised as a semi-quantitative measure of exercise capacity [1]. The 6-minute walking distance (6 MWD) also serves as primary or key secondary endpoint in numerous clinical trials assessing the efficacy of pharmacotherapies in various forms of PH [2, 3]. Furthermore, the 6MWD is among the key non-invasive measures of multi-modal risk assessment in pulmonary arterial hypertension (PAH) [4–6]. In this context, cut-off values of 440 m and 165 m have been validated to indicate low, intermediate and high mortality risk, respectively, in the 3-strata model proposed by the current ESC/ERS guidelines [1], with an additional cut-off of 320 m to discriminate between intermediate-high and intermediate-low risk in the recently introduced 4-strata approach [7, 8].

Abstract
Pulmonary hypertension (PH) is a common condition in patients with left heart disease (LHD) that is highly relevant for morbidity and mortality. While post-capillary in nature, the pathophysiology of PH in patients with LHD (heart failure/cardiomyopathy, valvular heart disease; other: congenital/acquired) is complex, and decisions about management strategies are challenging. Recently, the updated European Society of Cardiology/European Respiratory Society guidelines on the diagnosis and treatment of PH revisited hemodynamic definitions and the sub-classification of post-capillary PH, and provided numerous new recommendations on the diagnosis and management of PH associated with various types of LHD. Here, we review several novel aspects that focus on: (a) updated hemodynamic definitions, including the distinction between isolated post-capillary PH (IpcPH) and combined post- and pre-capillary PH (CpcPH); (b) the pathogenesis of PH-LHD, considering various components contributing to PH, such as pulmonary congestion, vasoconstriction, and vascular remodeling; (c) the prognostic relevance of PH and hemodynamic markers; (d) the diagnostic approach to PH-LHD; (e) management strategies in PH-LHD, distinguishing between targeting the underlying left heart condition, the pulmonary circulation, and/or impaired right ventricular function. In conclusion, precise clinical and hemodynamic characterization and detailed phenotyping are essential for prognostication and the management of patients with PH-LHD.

Abstract
AIMS Guideline recommendations highlight the critical role of combination therapy for the treatment of pulmonary arterial hypertension (PAH). Conversely, registry data demonstrate that a considerable number of PAH patients remain on monotherapy. The reasons for this discrepancy remain elusive. The aim of this study was to assess the patient profiles, treatment patterns, and disease characteristics of patients diagnosed with PAH who were kept on monotherapy at experienced pulmonary hypertension (PH) centres and to capture potential reasons for monotherapy. METHODS AND RESULTS We analysed the patient profiles of 182 patients on monotherapy with PAH-targeted drugs, managed at experienced PH expert centres (Cologne, Giessen, Heidelberg, and Dresden). Patients were identified based on their latest follow-up visit and analysed retrospectively from the time of PAH diagnosis to last follow-up. Patients were dichotomized by age, and patient characteristics, treatment patterns, response to therapy, change in risk status, and drug tolerability were recorded during the course of their disease. Patients' mean age was 69.1 ± 13.1 years at the most recent follow-up (Key Time Point 1) and 64.5 ± 14.9 years at the time of diagnosis (Key Time Point 2). The mean time on monotherapy was 60.7 ± 53.8 months; 35.7/64.3% of patients were male/female. The majority (66.5%) had idiopathic PAH, followed by PAH associated with connective tissue disease (17.0%) and portopulmonary PH (8.2%). Among patients on monotherapy, there were five main clusters: (i) patients with failed escalation attempts mostly because of intolerability (26.9%); (ii) low risk on monotherapy, favourable response, and no reason for escalation (24.2%); (iii) patients with mild PAH (36.3%); (iv) elderly patients with PAH and multiple co-morbidities (38.5%); and (v) patients with associated forms of PAH where the level of evidence for combination therapies is considered low (16.5%). There were substantial differences between patients above or below the median age (68 years). The most frequently used monotherapy for PAH was phosphodiesterase type 5 inhibitors (75.3%). CONCLUSIONS A considerable number of PAH patients are on monotherapy at large PH expert centres, characterized by specific reasons that justify this kind of treatment. Nevertheless, as comprehensive treatment strategies have shown improved long-term outcomes even in mildly symptomatic patients, each case of monotherapy should be justified.

Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) is a progressive disease with limited survival. Iron deficiency (ID) correlates with disease severity and mortality. While oral iron supplementation was shown to be insufficient in such patients, the potential impact of parenteral iron on clinical measures warrants further investigation. METHODS We retrospectively analysed the long-term effects of intravenous ferric carboxymaltose (FCM) on iron status and clinical measures in patients with PAH and ID [ferritin < 100 μg/L or ferritin 100-300 μg/L and transferrin saturation (TSAT) < 20%] who were on stable targeted PAH therapy, compared with matched controls without ID. Patients with ID received a single infusion of FCM (500 to 1000 mg). Clinical measures monitored included exercise capacity, World Health Organization (WHO) functional class, ESC/ERS risk status, and hospitalizations. The observation period was up to 18 months. RESULTS One hundred and seventeen patients (mean age 60.9 ± 16.1 years; 64.1% females) with confirmed PAH and on stable targeted therapy for ≥3 months were included (58 with and 59 patients without ID who did not receive FCM). In patients with ID, iron supplementation with FCM resulted in an immediate and sustained improvement of iron status for up to 18 months (serum iron, ferritin, TSAT, all P < 0.01). Fourteen patients in the FCM group received a second FCM infusion after 9.6 ± 4.8 months due to recurrent ID. At 6 and 18 months after FCM infusion, 6 min walk distance improved from 377.5 ± 15.9 at baseline to 412.5 ± 15.1 and 400.8 ± 14.5 m, respectively (both P < 0.05). WHO functional class (P < 0.05) and ESC/ERS risk status also improved, and there was a reduction of hospitalizations for worsening PAH in the 12 months post vs. prior to iron repletion (P = 0.029). No significant changes were observed in the control group. FCM was well tolerated in all patients, with no severe adverse events. CONCLUSIONS In addition to targeted therapy, correction of ID by parenteral iron supplementation with FCM appears feasible and safe, has sustained effects on iron status, and may improve the clinical status and hospitalization rates in patients with PAH. Larger controlled studies are required to confirm this finding.

Abstract
Pulmonary hypertension (PH) is an important contributor to morbidity and mortality in patients with left-sided heart disease, including valvular heart disease. In this context, elevated left atrial pressure primarily leads to the development of post-capillary PH. Despite the fact that repair of left-sided valvular heart disease by surgical or interventional approaches will improve PH, recent studies have highlighted that PH (pre- or post-interventional) remains an important predictor of long-term outcome. Here, we review the current knowledge on PH in valvular heart disease taking into account new hemodynamic PH definitions, and the distinction between post- and pre-capillary components of PH. A specific focus is on the precise characterization of hemodynamics and cardiopulmonary interaction, and on potential strategies for the management of residual PH after mitral or aortic valve interventions. In addition, we highlight the clinical significance of tricuspid regurgitation, which may occur as a primary condition or as a consequence of PH and right heart dilatation (functional). In this context, proper patient selection for potential tricuspid valve interventions is crucial. Finally, the article highlights gaps in evidence, and points toward future perspectives.
