AIM: Transthoracic echocardiography (TTE) is a fundamental investigation for the noninvasive assessment of pulmonary hemodynamics and right heart function. The aim of this study was to assess the correlation and agreement of Doppler calculation of right ventricular systolic pressure (RVSP) and pulmonary vascular resistance (PVR) using "chin" and "beard" measurements of tricuspid regurgitant velocity (TRVmax ), with invasive pulmonary artery systolic pressure (PASP) and PVR...

A 66-year-old man with seronegative, erosive rheumatoid arthritis for 12 years presented with malaise, elevated alkaline phosphatase and gamma-glutamyl transferase, and leg oedema. He subsequently developed ascites. No liver pathology was found, but cardiac analysis including right heart catheterisation revealed constrictive pericarditis. Rheumatoid constrictive pericarditis is a rare condition, but, despite current effective treatment for rheumatoid arthritis, still occurs. Diagnostic delay is frequent. Although mortality of the intervention is high, pericardiectomy is needed for most patients...

Although fetal heart rate variability (FHRV) has long been recognised as a powerful predictor of fetal wellbeing, the mechanisms by which it is reduced in the chronically hypoxic fetus have yet to be established. In particular, the physiological mechanism underlying the reduction of short term variation (STV) in fetal compromise remains unclear. In this study, we present a longitudinal study of the development of autonomic control of FHRV, assessed by indirect indices, time domain (SDNN, RMSSD) and power spectral analysis (LF, HF, LF/HF), in normoxic and chronically hypoxic, chronically catheterised, singleton fetal sheep over the last third of gestation...

Chronic thromboembolic pulmonary hypertension (CTEPH) is a severe complication of pulmonary embolism (PE). Its incidence following PE is debated. An active screening for CTEPH in patients with acute PE is yet to be recommended.This prospective, multicentre, observational study (INPUT on PE; ISRCTN61417303) included patients with acute PE from 11 centres in Switzerland from March 2009 to November 2016. Screening for possible CTEPH was performed at 6, 12 and 24 months using a step-wise algorithm that included a dyspnoea phone-based survey, transthoracic echocardiography, right heart catheterisation and radiologic confirmation of CTEPH...

Current guideline-recommended screening for pulmonary hypertension in patients with systemic sclerosis has not been evaluated in systemic lupus erythematosus (SLE), which is disproportionately prevalent in Asians. This multicentre, cross-sectional screening study aims to study the prevalence of pulmonary hypertension among SLE patients using these guidelines, and identify independent predictors and develop a prediction model for pulmonary hypertension in SLE patients. SLE patients from participating centres will undergo an echocardiography- and biomarker-based pulmonary hypertension screening procedure as in the DETECT study...

BACKGROUND: Cardiac output (CO) is a prognostic factor in pulmonary hypertension (PH). Right heart catheterisation using the direct Fick method or thermodilution (TD) is the reference technique for CO measurement. Impedance cardiography (IPc) is a known non-invasive method of measuring CO. OBJECTIVES: In our study, we assume that the measurement of CO by IPc using the PHYSIOFLOW® system is as accurate as TD or using the direct Fick method in patients with PH in group 1 or group 4...

Elevated mean pulmonary arterial pressure (MPAP; ≥21 mmHg) is sometimes seen in patients with idiopathic pulmonary fibrosis (IPF) and has an adverse impact upon survival. Although early diagnosis is crucial, there is no established screening tool that uses a combination of noninvasive examinations.We retrospectively analysed IPF patients at initial evaluation from April 2007 to July 2015 and, using logistic regression analysis, created a screening tool to identify elevated MPAP. Internal validation was also assessed for external validity using a bootstrap method...

Pulmonary arterial hypertension (PAH) is a rare disorder that can be drug-induced, mostly following treatment by appetite-suppressant drugs. We report four cases of patients who developed PAH following a treatment by leflunomide for rheumatoid arthritis, psoriatic arthritis or undetermined connective tissue disease. All patients described a progressive dyspnea from grade II to IV of NYHA classification; clinical examination found signs of heart failure. PAH was finally diagnosed and confirmed by right heart catheterisation...

There is growing recognition of the clinical importance of pulmonary haemodynamics during exercise, but several questions remain to be elucidated. The goal of this statement is to assess the scientific evidence in this field in order to provide a basis for future recommendations.Right heart catheterisation is the gold standard method to assess pulmonary haemodynamics at rest and during exercise. Exercise echocardiography and cardiopulmonary exercise testing represent non-invasive tools with evolving clinical applications...

BACKGROUND: Reliable markers of early disease are needed in pulmonary arterial hypertension (PAH). As measures of the contribution of abnormal vascular compliance to overall vascular resistance, resting and exercise pulmonary capacitance-defined as the stroke volume divided by the change in pulmonary pulse pressure-may be sensitive markers of early disease. METHODS: We examined all patients in our pulmonary hypertension database with idiopathic PAH, who had undergone rest and exercise right heart catheterisation in one sitting...

Screening is important to determine whether patients with systemic sclerosis (SSc) have pulmonary hypertension because earlier pulmonary hypertension treatment can improve survival in these patients. Although decreased transfer factor of the lung for carbon monoxide (TLCO) is currently considered the best pulmonary function test for screening for pulmonary hypertension in SSc, small series have suggested that partitioning TLCO into membrane conductance (diffusing capacity) for carbon monoxide (DMCO) and alveolar capillary blood volume (VC) through combined measurement of TLCO and transfer factor of the lung for nitric oxide (TLNO) is more effective to identify pulmonary hypertension in SSc patients compared with TLCO alone...

- Chronic thromboembolic pulmonary hypertension (CTEPH), characterised by pulmonary hypertension and persistent perfusion defects despite adequate anticoagulation, causes significant morbidity and mortality.- Persistent dyspnoea after acute pulmonary embolism is frequent and an indication for additional diagnostics. Only a minority of these patients develop CTEPH.- Echocardiography and perfusion scintigraphy are the cornerstone of diagnostics when suspecting CTEPH. Right-heart catheterisation and pulmonary angiography should confirm the diagnosis...

OBJECTIVES: To determine the prevalence and factors associated with persistent pulmonary hypertension (PH) following transcatheter aortic valve replacement (TAVR) and its relationship with long-term mortality. METHODS: Consecutive patients who underwent TAVR from July 2011 through January 2016 were studied. The prevalence of baseline PH (mean pulmonary artery pressure ≥25 mm Hg on right heart catheterisation) and the prevalence and the predictors of persistent≥moderate PH (pulmonary artery systolic pressure (PASP)>45 mm Hg on 1 month post-TAVR transthoracic Doppler echocardiography) were collected...

BACKGROUND: B-type natriuretic peptide (BNP) has been found to be inversely related to peak oxygen consumption (peak VO2) in various patient populations. However, in these studies, circulating plasma BNP, i.e. the net effect of release and elimination, rather than cardiac BNP release has been measured. We assessed the relationship between the transcardiac BNP gradient [ΔBNPCS-A, i.e. the difference between BNP in coronary sinus (BNPCS) and arterial (BNPA) plasma] and peak VO2 in healthy subjects with a view to better understanding the regulation of cardiac BNP release in humans...
