We invited 4 experts to a telephone roundtable facilitated by guest editor Jim White, MD, PhD, on April 13, 2012, to discuss the results of the recent Phase III trial, the Imatinib in Pulmonary Arterial Hypertension (IMPRES) trial (NCT00902174). Investigators enrolled patients with pulmonary arterial hypertension with severe hemodynamic impairment at catheterization despite treatment with 2 background therapies. Patients were randomized to placebo or 200 mg imatinib twice daily for 6 months of therapy to assess efficacy. Participating in the discussion were Mardi Gomberg-Maitland, MD, MSc, Associate Professor of Medicine and Director, Pulmonary Hypertension Center, University of Chicago; Iona Preston, MD, Co-director, Pulmonary Hypertension Center, Tufts University Medical Center, Boston; Jeremy Feldman, MD, Director, Pulmonary Hypertension Program, Medical Director of Research, Arizona Pulmonary Specialists, Phoenix; Stephen Mathai, MD, MHS, Assistant Professor of Medicine, The Johns Hopkins School of Medicine, Baltimore.

Background The diagnosis of pulmonary arterial hypertension requires right heart catheterization (RHC) which is typically performed via proximal venous access (PVA). Antecubital venous access (AVA) is an alternative approach for RHC that can minimize complications, decrease procedural duration and allow for immediate patient recovery. A direct comparison between the two procedures in patients with pulmonary hypertension (PH) is lacking. Objectives To determine the feasibility, safety, and adoption rates of AVA-RHC as compared with ultrasound-guided PVA in a subpopulation of patients with PH. Methods All patients who underwent RHC for evaluation of PH between December 2014 and March 2017 at a single large academic medical center were included in this study. Demographic, procedural and outcomes data were retrieved from the medical records. Results In total, 159 RHC were included (124 AVA, 35 PVA). The duration of RHC was significantly shorter in the AVA compared with PVA group (53 (IQR 38–70) vs. 80 (IQR 56–95) min, respectively, p < 0.001). 19% of AVA (24/124) procedures were switched to PVA. Failed attempts at AVA were more common in scleroderma (50% failure rate). Success rate of AVA increased from 81.2% to 93.3% from the first to last quartile. Fluoroscopy time was similar in both groups, the difference between the groups in the radiation dose are not statistically significant (54.5 (IQR 25–110) vs. 84.5 (IQR 30–134)). Conclusion AVA-RHC is a feasible and safe alternative to PVA in patients with PH who are evaluated for pulmonary arterial hypertension diagnosis. Our experience and rapid adoption rate support the use of AVA as the preferred access site for RHC in uncomplicated PH patients.

Abstract Background Eisenmenger syndrome is a multisystem disorder, characterised by a significant cardiac defect, severe pulmonary hypertension and long-standing cyanosis. Despite the availability of pulmonary hypertension therapies and improved supportive care in specialist centres, Eisenmenger patients are still faced with significant morbidity and mortality. Case presentation We describe the case of a 44-year-old woman with Eisenmenger syndrome secondary to a large secundum atrial septal defect. Her pulmonary vascular disease was treated with pulmonary vasodilators, but she experienced a progressive decline in exercise tolerance, increasing atrial arrhythmias, resulting in referral for transplantation. Her condition was complicated by significant recurrent haemoptysis in the context of extremely dilated pulmonary arteries and in-situ thrombosis, which prompted successful heart and lung transplantation. She made a slow recovery but remains well 3 years post-transplant. Conclusions Patients with Eisenmenger syndrome secondary to a pre-tricuspid lesion, such as an atrial septal defect have a natural history that differs to patients with post-tricuspid shunts; the disease tends to present later in life but is more aggressive, prompting early and aggressive medical intervention with pulmonary arterial hypertension therapies. This case illustrates that severe recurrent haemoptysis can be an indication for expediting transplantation in Eisenmenger syndrome patients.

Pulmonary hypertension (PH) is a condition characterised by an abnormal elevation of pulmonary artery pressure caused by an increased pulmonary vascular resistance, frequently leading to right ventricular failure and reduced survival. Marked sexual dimorphism is observed in patients with pulmonary arterial hypertension, a form of pulmonary hypertension with a particularly severe clinical course. The incidence in females is 2–4 times greater than in males, although the disease is less severe in females. We review the contribution of the sex chromosomes to this sex dimorphism highlighting the impact of proteins, microRNAs and long non-coding RNAs encoded on the X and Y chromosomes. These genes are centrally involved in the cellular pathways that cause increased pulmonary vascular resistance including the production of reactive oxygen species, altered metabolism, apoptosis, inflammation, vasoconstriction and vascular remodelling. The interaction with genetic mutations on autosomal genes that cause heritable pulmonary arterial hypertension such as bone morphogenetic protein 2 (BMPR2) are examined. The mechanisms that can lead to differences in the expression of genes located on the X chromosomes between females and males are also reviewed. A better understanding of the mechanisms of sex dimorphism in this disease will contribute to the development of more effective therapies for both women and men.

Abstract Background Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare form of pulmonary hypertension caused by blood clots and scar tissue in the blood vessels of the lungs. Health-related quality of life is often significantly impaired in patients with CTEPH. However, a better understanding of how CTEPH symptoms affect patients’ lives is needed to optimally assess the impact of the disease and treatment. Objectives This qualitative study aimed to better understand the symptoms of CTEPH and how they affect patients’ lives, as well as to determine the appropriateness of the Pulmonary Arterial Hypertension – Symptoms and Impact (PAH-SYMPACT™) questionnaire for use in this patient population. Methods Adults diagnosed with CTEPH, recruited from two clinical sites in the US, participated in one-to-one qualitative telephone interviews. They described their experience of CTEPH symptoms and the impact these symptoms have on their lives. They also provided feedback on the comprehensibility and relevance of the PAH-SYMPACT™‘s instructions, items, and response options. Results Participants (N = 12) had a mean age of 62.5 years. Two thirds were female and most (83%) had undergone pulmonary endarterectomy and/or balloon pulmonary angioplasty. The most frequently endorsed symptoms were shortness of breath (endorsed by all 12 participants), fatigue (11 participants), and lightheadedness (10 participants). All participants identified shortness of breath as an “extremely important” symptom, and seven participants rated fatigue as “extremely important.” The most frequent impacts of CTEPH were on ability to walk quickly (endorsed by all 12 participants), ability to walk up inclines or stairs (11 participants), and ability to carry things (11 participants). The PAH-SYMPACT™ items were relevant to most participants and reflected their experience of CTEPH. All participants indicated that no important CTEPH symptoms were missing from the PAH-SYMPACT™. Overall, the instructions, items, and response options of the PAH-SYMPACT™ were clear and easy to understand. Conclusions The symptoms and impacts experienced by patients with CTEPH align with items included in the PAH-SYMPACT™. The PAH-SYMPACT™ appears to be fit for purpose for assessing disease status in patients with CTEPH.

Abstract Introduction Sleep disordered breathing (SDB) is a group of ventilatory disorders during sleep which includes obstructive sleep apnea (OSA), central sleep apnea (CSA), and sleep related hypoventilation. In patients with SDB, the prevalence of pulmonary hypertension (PH) ranges from 17% to 52%. While SDB is prevalent in the general population with recent estimates of 20% to 30%, in those with cardiovascular disease, particularly left ventricular failure, there is a higher reported prevalence of 47%. Aims The aims of this study were to determine the prevalence and prognostic relevance of sleep apnea in a cohort of patients with newly diagnosed pulmonary arterial hypertension (ESC/WHO Group 1 pulmonary hypertension). Methods We evaluated prospectively 76 patients with the pulmonary arterial hypertension (mean age 54±16 years; 45% male). All patients underwent right heart catheterisation, clinical assessments, sleep study, standard laboratory testing and evaluation of subjective sleepiness by the Epworth Sleepiness Scale. Sleep test was provided with an ApneaLink Plus, consisting of nasal pressure sensor, respiratory effort band, and pulse oximeter worn on the finger. Subjects previously treated for or diagnosed with SDB were excluded from the study. Results Sleep apnea (SA) – defined as apnea-hypopnea index (AHI) ≥5/h – was found in 59 (77.6%) of the pulmonary arterial hypertension (PAH) patients. Mean AHI in the cohort of PAH patients with SA was 26.1±16.6/h. Mean follow-up was 24 months, during which 15 (19.7%) patients died. Characteristics of parameters related to SA in groups of survivors and deceased are in table 1. From the sleep apnea-related parameters, only time with O2Sat &lt;90% – T90 was significantly associated with mortality (AUC 0.856; 95% CI 0.693 – 1.019; p&lt;0.001). Conclusions The presence of sleep apnea in pulmonary arterial hypertension patients is high. The prevalence of sleep apnea is higher in PAH patients than in the general population. The presence of sleep apnea in patients with PAH was not associated with worse prognosis, but noctural hypoxemia (time with O2Sat &lt;90%) was related to poor prognosis. Sleep apnea in patients with PAH should be screened for systematically. Funding Acknowledgement Type of funding source: None
