Abstract Background There is an increasing number of elderly patients with pulmonary arterial hypertension, and their characteristics differ from those of young or middle-aged patients with this condition. Case Summary A 73-year-old woman with a history of myocardial infarction and cardiovascular risk factors was admitted to the hospital with 2-week exertional dyspnoea. Her initial diagnosis was heart failure with preserved ejection fraction, but the symptoms persisted despite receiving treatment with diuretics. Additional tests showed a significant decrease in diffusing capacity of carbon monoxide and findings suggestive of severe pulmonary hypertension. Contrast-enhanced computed tomography of the chest, and pulmonary angiography, showed no narrowing or obstruction of the pulmonary arteries. Right heart catheterization revealed hemodynamic data implying pre-capillary pulmonary hypertension. Her condition gradually deteriorated to World Health Organization functional class IV, and sequential combination therapy with tadalafil, macitentan, and selexipag was initiated with a pulmonary arterial hypertension diagnosis; however, she died 1 month later. Pathological findings in autopsy were consistent with pulmonary arterial hypertension, and some parts of the lungs revealed the presence of obstructive and interstitial lung disease. Discussion The majority of elderly patients with pulmonary arterial hypertension might have multimorbidity. However, there is no specific treatment strategy. It is associated with diagnostic delay and worse prognosis; therefore, early suspicion and comprehensive tests, including right heart catheterization, are essential for better management.

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.

Pulmonary arterial hypertension has been reported with a prevalence of 7.9% in patients with anti-synthetase syndrome; however, anti-synthetase syndrome associated with pulmonary veno-occlusive disease (PVOD) has never before been described in the literature. We present a novel case of anti-synthetase syndrome-associated PVOD in a patient who presented with hypoxic respiratory failure associated with right heart failure and was diagnosed with anti-synthetase syndrome based on his autoimmune serology and pre-capillary pulmonary hypertension on right heart catheterization. He was initiated on pulmonary arterial hypertension therapy, but with escalating dose of parenteral epoprostenol, experienced acute clinical worsening with chest imaging concerning for PVOD that was confirmed on autopsy. Anti-synthetase syndrome can be associated with PVOD, and it should be suspected in patients who have evidence of pre-capillary pulmonary hypertension and who deteriorate with the initiation of pulmonary hypertension-specific therapy.

Abstract Objectives Pulmonary hypertension (PH) in patients with CTD is a heterogeneous condition affected by left heart disease, chronic lung disease and thromboembolism as well as pulmonary vascular disease. Recent studies using cardiac magnetic resonance (CMR) have shown that right ventricular dysfunction is predictive for mortality in patients with PH, but limited to pulmonary arterial hypertension. This study aimed to analyse prognostic factors in PH-CTD. Methods This retrospective analysis comprised 84 CTD patients, including SSc, who underwent both CMR and right heart catheterization from 2008 to 2018. Demographics, laboratory findings, and haemodynamic and morphological parameters were extracted. The prognostic value of each parameter was evaluated by multivariate analysis using covariables derived from propensity score to control confounding factors. Results Of 84 patients, 65 had right heart catheterization-confirmed PH (54 pulmonary arterial hypertension, 11 non-pulmonary arterial hypertension). Nine out of these PH patients died during a median follow-up period of 25 months. In 65 patients with PH, right ventricular end-diastolic dimension index (RVEDDI) evaluated by CMR was independently associated with mortality (hazard ratio 1.24; 95% CI: 1.08–1.46; P = 0.003). In a receiver operating characteristic analysis, RVEDDI highly predicted mortality, with area under the curve of 0.87. The 0.5–2-year follow-up data revealed that RVEDDI in both survivors and non-survivors did not significantly change over the clinical course, leading to the possibility that an early determination of RVEDDI could predict the prognosis. Conclusion RVEDDI simply evaluated by CMR could serve as a significant predictor of mortality in PH-CTD. A further validation cohort study is needed to confirm its usability.

In our country when it comes to diagnosis and treatment of Pulmonary Hypertension (PH) especially Pulmonary Arterial Hypertension (PAH), it seems that it is still an Orphan Lung disease. Whether it is data about its prevalence in our country, available diagnostic services or treatment options, one may easily feel the scarcity in all mentioned areas. Most current classification of PH, categorizes it into 5 groups.1 However this categorization requires availability of diagnostic tools especially right heart catheterization data to classify and know the severity of PH and to offer targeted treatment to patients who belong to group 1 PH i.e. Pulmonary Arterial Hypertension (PAH). Studies done about PH prevalence in Pakistan have mainly focused on data in selected patients group e.g. in patients with Chronic Obstructive Pulmonary Diseases (COPD) or Systemic Lupus Erythematosus (SLE).2,3 All of these studies relied on diagnosis without using the diagnostic bench mark i.e. Right heart catheterization. Moreover, effects of targeted treatment for PAH have also been studied only in selected group of patients e.g. COPD.4,5 While above work by the learned colleagues has to be appreciated, it emphasizes the need to, Spread the awareness about PH more so to reduce inadvertent use of targeted treatment which may prove detrimental outside group 1 PH and should only be considered at specialized centers. Develop specialized centers with required diagnostic services especially Lung functional and anatomical evaluation and Right heart catheterization. Establish PH registries (at least one in each province) which can play a vital role to collect data and ensure effective evidence based patient management. This may be an uphill task however the right direction to move forward.   REFERENCES Simonneau G, Montani D, David SC, Christopher PD, Michael AG, Michael K, at el. Paul G.

Background: Pulmonary arterial hypertension (PAH) is a severe disease characterized by a progressive increase of pulmonary pressure and resistance leading to right heart failure. Pulmonary arterial hypertension is commonly diagnosed at a late stage of the disease and is associated with progressive clinical deterioration and premature death. The assessment of pulmonary artery pressure is important in clinical management and prognostic evaluation of patients with cardiovascular and pulmonary disease. Although PH can be detected invasively by right ventricular (RV) catheterization, accurate non-invasive assessment by echocardiography has many advantages. Reliable non-invasive evaluation of pulmonary pressure at present is still a problem as echocardiographic measurement of pulmonary hypertension relies on the presence of tricuspid regurgitation (TR). Objective: The purpose of this study was to determine whether right ventricular end diastolic diameter can predict the presence of pulmonary hypertension. Methods: Eighty consecutive patients with echo detectable tricuspid regurgitation who underwent right heart catheterization for either diagnostic or therapeutic procedure were recruited. They were divided into two groups on the basis of pulmonary artery systolic pressure (PASP). Group I consists of 40 patients with PASP >35 mm Hg and Group II 40 patients having PASP d• 35 mm Hg. Right ventricular end-diastolic diameter (RVD) was measured in the apical 4 chamber view. PASP was measured from right heart catheterization. Results: The RVD has strong correlation with catheter-derived PASP, at a cutoff value of >3 cm, predicted the presence of PAH with 78% sensitivity and 71% specificity. Conclusion: RVD is a good non-invasive predictor for PAH. RVD can predict the presence of PAH even in absence of TR and correlates well with PASP measured by RV catheterization.Bangladesh Heart Journal 2015; 30(2) : 48-52

Pulmonary arterial hypertension (PAH) is a disease of the lung blood vessels that results in right heart failure. PAH is thought to occur in about 5% to 10% of patients with hepatosplenic schistosomiasis, particularly due to S. mansoni. The lung blood vessel injury may result from a combination of embolization of eggs through portocaval shunts into the lungs causing localized Type 2 inflammatory response and vessel remodeling, triggering of autonomous pathology that becomes independent of the antigen, and high cardiac output as seen in portopulmonary hypertension. The condition is likely underdiagnosed as there is little systematic screening, and risk factors for developing PAH are not known. Screening is done by echocardiography, and formal diagnosis requires invasive right heart catheterization. Patients with Schistosoma-associated PAH show reduced functional capacity and can be treated with pulmonary vasodilators, which improves symptoms and may improve survival. There are animal models of this disease that might help in understanding disease pathogenesis and identify novel targets to screen and treatment. Pathogenic mechanisms include Type 2 immunity and activation and signaling in the TGF-β pathway. There are still major uncertainties regarding Schistosoma-associated PAH development, course and treatment.
