Introduction: Pulmonary hypertension is defined as being a haemodynamic state, wherein the mean pulmonary artery pressure measured during right heart catheterization is equal or greater than 25 mmHg. As a result, right ventricular heart failure develops and clinical symptoms such as dyspnea, fatigue, weakness, angina and fainting occur. The aim: To highlight the role of imaging techniques in diagnostic process for pulmonary hypertension. Review and Disscusion: The diagnosis of pulmonary hypertension is multistage and often requires a number of studies. Currently, imaging techniques play a significant role in the diagnostic algorithm for pulmonary hypertension due to the fact that they are non-invasive and readily available, and many of their parameters are closely related to pulmonary hemodynamics. Conclusions: The diagnosis of pulmonary hypertension requires a multistep approach and a number of imaging studies. The suspicion of the disease is based on medical history, clinical symptoms and chest radiogram. Echocardiography plays a crucial role in pulmonary hypertension detection. A computed tomography and cardiac magnetic resonanceare valuable methods in determining the cause of suspected or confirmed pulmonary hypertension.

Background: The development of right ventricular (RV) dysfunction in patients with pulmonary hypertension (PH) has been associated with adverse outcomes. Right atrial (RA) function could be a prognostic factors as well as RV function, but non-invasive evaluation of RA function is limited. Our objective was thus to test the hypothesis that RA function was associated with hemodynamic parameters of RV performance in PH patients. Methods: Eighty PH patients with mean pulmonary artery pressure (PAP) of 40±11mmHg (all≥25mmHg) were recruited in this study. RA function was assessed by using two-dimensional speckle-tracking strain from RV-focused apical 4-chamber view. RA strain was calculated with the reference point set at the P wave, which enabled the recognition of peak negative (RAneg), positive strain (RAposi), and the sum of those values (RAtotal), corresponding to RA contractile, conduit, and reservoir function, respectively. All patients underwent right-heart catheterization for measurement of mean PAP and pulmonary vascular resistance (PVR). Results: RAneg (r=0.24 and p=0.03), RAposi (r=0.31 and p=0.01) and RAtotal (r=0.35 and p=0.001) were significantly correlated with mean PAP. In addition, RAposi (r=0.41 and p<0.001) and RAtotal (r=0.44 and p<0.001) were also correlated with PVR. Conclusions: Non-invasively assessed RA strains were associated with mean PAP and PVR. RA strain may be of a valuable additive factor for the management of PH patients, and thus have potential clinical applications.

Pulmonary hypertension is a hemodynamic disorder defined by abnormally high pulmonary artery pressure that affects the arteries in your lungs and the right side of your heart. In this study, hepatic venous duplex will be done to diagnose and quantify the PH. So that Patients can avoid unnecessary invasive right heart catheterization. This practical demonstration is the key to enrich our experience and knowledge in the field of PH. Objectives of this study was to assess PH status by Hepatic venous Duplex (HVD) as well by right heart catheterization and to compare them. This study was conducted in the Department of Cardiology, BSMMU, Shahbagh, Dhaka extending from July 2018 to December 2019. Total 100 (One hundred) subjects were enrolled in this study. It was an Observational study and includes the subjects between 18 years to 45 years of age. Results of this study shows very close proximity to that of Right heart catheterization. Hemodynamic changes in Hepatic venous duplex study could be used as an alternative diagnostic tool for evaluating moderate to severe pulmonary hypertension. This method could counteract the weakness of the currently used diagnostic methods and improve the accuracy of assessing pulmonary hypertension when combined with other methods.

Systemic sclerosis is the most common autoimmune disease associated with pulmonary hypertension. Pulmonary hypertension is a potential predictor of early death, and therefore, recently, interest in a comprehensive study of the diagnosis of pulmonary hypertension associated with systemic sclerosis has been increasing among researchers. Aim. Consideration of current diagnostic issues, as well as the principles of using diagnostic algorithms to verify pulmonary hypertension associated with systemic sclerosis, applied in daily clinical practice. Material and methods. In order to study the literature data, a search was carried out for information on this problem up to 10 years in depth in the Web of Science, PubMed/MEDLINE. During the search, the following terms were used individually and in combination: "systemic sclerosis", "pulmonary hypertension", "DETECT algorithm", "catheterization of the right heart chambers". The main search criteria were studies based on the study of patients with pulmonary hypertension associated with systemic sclerosis: meta-analyzes, original studies, retrospective and cohort studies. Results and discussion. The clinical symptoms of pulmonary hypertension can be nonspecific, which greatly complicates the diagnosis of the disease in the early stages. The absence of a specific clinical picture before the development of an advanced stage of pulmonary hypertension leads to late verification of the diagnosis. Key algorithms used in the daily practice of a doctor make it possible to minimize the number of undiagnosed cases of pulmonary hypertension. Conclusions. Diagnosis of PH associated with systemic sclerosis is often challenging for clinicians to practice. Early diagnosis and therefore treatment of PH are of paramount importance as they improve survival rates in patients with systemic sclerosis. Keywords: systemic sclerosis, pulmonary hypertension, screening, DETECT algorithm, right heart catheterization.

Background * These authors contributed equally as last authors. Balloon pulmonary angioplasty is an evolving, interventional treatment option for inoperable patients with chronic thromboembolic pulmonary hypertension (CTEPH). Pulmonary hypertension at rest as well as exercise capacity is considered to be relevant outcome parameters. The aim of the present study was to determine whether measurement of pulmonary hemodynamics during exercise before and six months after balloon pulmonary angioplasty have an added value. Methods From March 2014 to July 2018, 172 consecutive patients underwent balloon pulmonary angioplasty. Of these, 64 consecutive patients with inoperable CTEPH underwent a comprehensive diagnostic workup that included right heart catheterization at rest and during exercise before balloon pulmonary angioplasty treatments and six months after the last intervention. Results Improvements in pulmonary hemodynamics at rest and during exercise, in quality of life, and in exercise capacity were observed six months after balloon pulmonary angioplasty: WHO functional class improved in 78% of patients. The mean pulmonary arterial pressure (mPAP) at rest was reduced from 41 ± 9 to 31 ± 9 mmHg (p < 0.0001). The mPAP/cardiac output slope decreased after balloon pulmonary angioplasty (11.2 ± 25.6 WU to 7.7 ± 4.1 WU; p < 0.0001), and correlated with N-terminal fragment of pro-brain natriuretic peptide (p = 0.035) and 6-minute walking distance (p = 0.01). Conclusions Exercise right heart catheterization provides valuable information on the changes of pulmonary hemodynamics after balloon pulmonary angioplasty in inoperable CTEPH patients that are not obtainable by measuring resting hemodynamics.

Pulmonary hypertension (PH) is a frequently encountered complication of chronic obstructive pulmonary disease (COPD) and is associated with worsened clinical symptoms and prognosis. The prevalence of PH-COPD is not concretely established as classification criteria vary historically, but the presence of severe disease out of proportion to underlying COPD is relatively rare. Right heart catheterization, the gold standard in diagnosis of PH, is infrequently performed in COPD, and the overlap in the clinical symptoms of PH and COPD presents diagnostic challenges. Proven treatments are limited. Trials exploring the use of vasodilator therapy in this patient group generally demonstrate improvements in hemodynamics accompanied by worsening gas exchange without clearly demonstrated improvements in clinically meaningful outcomes. In-depth workup of underlying pulmonary hypertension and use of pulmonary vasodilator medications may be appropriate on an individual basis. We present a case study and a review and discussion of the pertinent literature on this topic.

Sarcoidosis-associated pulmonary hypertension (SAPH) has been reported in 10% of all sarcoidosis patients. In the United States, the prevalence is similar to that reported for scleroderma. There are several possible mechanisms for SAPH, including vascular compression, granulomatous angiitis, left ventricular (LV) dysfunction, and fibrosis of lung tissue. The prognosis of those with LV dysfunction is significantly better than those with precapillary pulmonary hypertension. Screening for SAPH includes evaluation of dyspnea by 6-minute walk test, echocardiography, and measurement of pulmonary artery diameter on computer tomographic scan. Right heart catheterization remains the definitive test for characterizing SAPH. Treatment for precapillary hypertension has been shown to improve pulmonary hemodynamics. However, it is still unclear whether such treatments will change the natural course of the disease, especially in those with severe fibrosis.
