Abstract Purpose: Studies in the context of research have shown a significant disagreement between the echocardiographic measurement of the systolic pulmonary artery pressure (sPAP) and right atrial pressure (RAP) and that obtained by right heart catheterization (RHC). We compare measurements of sPAP and RAP, verified by transthoracic echocardiogram (TTE) with those detected by RHC in patients being investigated for pulmonary hypertension (PH). Methods: Cross-sectional study was performed in a context of usual clinical practice in the public referral center for PH, including patients with high or intermediate echocardiographic probability of pulmonary arterial hypertension and chronic thromboembolic PH. Bland-Altman test was used to assess the agreement amongthe values and ROC curve to identify sPAP and tricuspid regurgitation velocity (TRV) values ​​with better accuracy. Clinically acceptable differences of 10 mmHg for sPAP and 5 mmHg for RAP were considered.Results: Ninety-five patients were included. The Bland-Altman analysis showed a bias of 8.03 mmHg for sPAP and -3.30 mmHg for RAP. Area under the curve for sPAP and TRV measured by TTE were 0.936(95% CI: 0.836-1.0) and 0.919(95% CI: 0.837-1.0), respectively. According to the pre-defined pressure differences, only 33.4% of the echocardiographic estimate of sPAP and 55.1% of RAP were accurate, as compared to the measurements obtained by RHC. Conclusions: Real life study revealed that echocardiographic evaluation demonstrated a high discriminatory power for diagnosis of PH, but sPAP and RAP measurements showed significant disagreements in relation to hemodynamic measures. The technical improvement of diagnostic services may contribute to the earlier recognition of this condition by TTE.

Abstract BACKGROUND. Accurate assessment of pulmonary artery (PA) pressures is integral to diagnosis, follow-up and therapy selection in pulmonary hypertension (PH). Despite wide utilization, the accuracy of echocardiography to estimate PA pressures has been debated. We aimed to evaluate echocardiographic accuracy to estimate right heart catheterization (RHC) based PA pressures in a large, dual-centre hemodynamic database. METHODS. Consecutive PH referrals that underwent comprehensive echocardiography within 3 hours of clinically indicated right heart catheterization were enrolled. Subjects with absent or severe, free-flowing tricuspid regurgitation (TR) were excluded. Accuracy was defined as mean bias between echocardiographic and invasive measurements on Bland-Altman analysis for the cohort and estimate difference within ±10mmHg of invasive measurements for individual diagnosis. RESULTS. In 419 subjects, echocardiographic PA systolic and mean pressures demonstrated minimal bias with invasive measurements (+2.4 and +1.9mmHg respectively) but displayed wide limits of agreement (-20 to +25 and -14 to +18mmHg respectively) and frequently misclassified subjects. Recommendation-based right atrial pressure (RAP) demonstrated poor precision and was falsely elevated in 32% of individual cases. Applying a fixed, median RAP to echocardiographic estimates resulted in relatively lower bias between modalities when assessing PA systolic (+1.4mmHg; 95% limits of agreement +25 to –22mmHg) and PA mean pressures (+1.4mmHg; 95% limits of agreement +19 to -16mmHg).CONCLUSIONS. Echocardiography accurately represents invasive PA pressures for population studies but may be misleading for individual diagnosis owing to modest precision and frequent misclassification. Recommendation-based estimates of RAPmean may not necessarily contribute to greater accuracy of PA pressure estimates.

Background We investigated changes in right atrial pressure (RAP) during exercise and their prognostic significance in patients assessed for pulmonary hypertension (PH). Methods and Results Consecutive right heart catheterization data, including RAP recorded during supine, stepwise cycle exercise in 270 patients evaluated for PH, were analyzed retrospectively and compared among groups of patients with PH (mean pulmonary artery pressure [mPAP] ≥25 mm Hg), exercise‐induced PH (exPH; resting mPAP <25 mm Hg, exercise mPAP >30 mm Hg, and mPAP/cardiac output >3 Wood Units (WU)), and without PH (noPH). We investigated RAP changes during exercise and survival over a median (quartiles) observation period of 3.7 (2.8–5.6) years. In 152 patients with PH, 58 with exPH, and 60 with noPH, median (quartiles) resting RAP was 8 (6–11), 6 (4–8), and 6 (4–8) mm Hg ( P <0.005 for noPH and exPH versus PH). Corresponding peak changes (95% CI) in RAP during exercise were 5 (4–6), 3 (2–4), and −1 (−2 to 0) mm Hg (noPH versus PH P <0.001, noPH versus exPH P =0.027). RAP increase during exercise correlated with mPAP/cardiac output increase ( r =0.528, P <0.001). The risk of death or lung transplantation was higher in patients with exercise‐induced RAP increase (hazard ratio, 4.24; 95% CI, 1.69–10.64; P =0.002) compared with patients with unaltered or decreasing RAP during exercise. Conclusions In patients evaluated for PH, RAP during exercise should not be assumed as constant. RAP increase during exercise, as observed in exPH and PH, reflects hemodynamic impairment and poor prognosis. Therefore, our data suggest that changes in RAP during exercise right heart catheterization are clinically important indexes of the cardiovascular function.

BackgroundAccording to current guidelines, the diagnosis of pulmonary hypertension (PH) relies on echocardiographic probability followed by right heart catheterization. How echocardiography predicts PH recently re-defined by a mean pulmonary artery pressure (mPAP) >20 mmHg instead of ≥25 mmHg and pulmonary vascular disease defined by a pulmonary vascular resistance (PVR) >3 or >2 Wood units has not been established.MethodsA total of 278 patients referred for PH underwent a comprehensive echocardiography followed by a right heart catheterization. Fifteen patients (5.4%) were excluded because of insufficient quality echocardiography.ResultsWith PH defined by a mPAP >20 mmHg, 23 patients had no PH, 146 had pre-capillary and 94 post-capillary PH. At univariate analysis, maximum velocity of tricuspid regurgitation (TRV) ≥2.9 and ≤3.4 m s−1, left ventricle (LV) eccentricity index >1.1, right ventricle (RV) outflow tract (OT) notching or acceleration time <105 ms, RV-LV basal diameter >1 and PA diameter predicted PH, whereas inferior vena cava diameter and right atrial area did not. At multivariable analysis, only TRV ≥2.9 m s−1 independently predicted PH. Additional independent prediction of PVR >3 Wood units was offered by LV eccentricity index >1.1 and RVOT acceleration time <105 ms and/or notching, but with no improvement of optimal combination of specificity and sensibility or positive prediction.ConclusionsEchocardiography as recommended in current guidelines can be used to assess the probability of re-defined PH in a referral center. However, the added value of indirect signs is modest and sufficient quality echocardiographic signals may not be recovered in some patients.

Abstract Background Pulmonary hypertension is a serious complication that can develop in patients with secundum Atrial Septal Defect (ASD) and based on Euro Heart Survey, 24,77% of ASD patients develop PH. The gold-standard for the diagnosis of pulmonary hypertension in ASD is right heart catheterization. However, in low-middle income country like Indonesia, right heart catheterization only available in a few centers while Indonesia is often referred as the world’s largest archipelago. Thus, there is a huge number of undiagnosed and untreated patients with ASD-PH in Indonesia, especially in patients who lives in rural and isolated area. This research was initiated to investigate the diagnostic value of simple 12-lead ECG in the diagnosis of pulmonary hypertension in ASD with the intention to help doctors in isolated area. Method We performed a cross-sectional study analyzing the 12-lead ECG and mean arterial pressure collected from right heart catheterization from 120 patients with secundum ASD aged &gt; 18 years old. The 12-lead ECG collected within 24 hours before RHC procedure. Results We analyzed the ECG and RHC from 60 subjects diagnosed with pulmonary hypertension and 60 subjects without pulmonary hypertension. We found that R in lead V1 + S in lead V6&gt; 12,5 mV, right axis deviation (RAD), and RV strain were independent predictors of pulmonary hypertension in secundum ASD. Based on Receiver Operator Characteristics (ROC), we obtained that R in V1 + S in V6&gt; 12,5 mm, right axis deviation (RAD), and RV strain has an Area Under of Curve (AUC) of 80,8%, 70,5%, and 85,6% respectively. We developed a scoring system and a score of &gt;5 have a sensitivity of 90%, specificity of 84,4%, positive predictive value of 84,4%, negative predictive value of 90%, and accuracy of 87,1%. We also developed a predictor for pulmonary vascular disease (low flow and high resistance PH) to predict wether the defect can be closed. We obtained that R in V6 + S in V6 &gt; 27,5 mm can predict a low flow high resistance pulmonary hypertension in secundum ASD with an AUC of 77,1% (CI 95% 58-96,1%) Conclusion ECG score of 12-lead ECG derived from this study can be used to predict PH in secundum ASD. It may help cardiologists or general practitioners in rural and isolated area to diagnose pulmonary hypertension in ASD and plan the best management for the patients.

Right heart catheterization is a unique tool not only in the diagnosis but also in the management of patients with a wide range of cardiovascular diseases. The technique dates back to the 18th century, but the biggest advances were made in the 20th century. This review focuses on pulmonary hypertension for which right heart catheterization remains the diagnostic gold standard. Right heart catheterization-derived parameters help classify pulmonary hypertension into several subgroups, assess risk of adverse events or mortality and make therapeutic decisions. According to the European Society of Cardiology guidelines pulmonary hypertension (PH) is defined as an increase in mean pulmonary artery pressure (PAPm) > 25 mmHg, whereas a distinction between pre- and post-capillary PH is made based on levels of pulmonary artery wedge pressure (PAWP). Moreover, right atrial pressure (RAP), cardiac index (CI) and mixed venous oxygen saturation (SvO2) are the only parameters recommended to assess prognosis and only in patients with pulmonary arterial hypertension (PAH). Patients with RAP > 14 mmHg, CI < 2.0 l/min/m2 and SvO2 < 60% are at high (> 10%) risk of death within the next year. The purpose of this paper is to show that RHC-derived parameters can be used on a considerably larger scale than currently recommended. Several prognostic parameters, with specific thresholds have been identified for each subtype of pulmonary hypertension and can be helpful in everyday practice for treatment of PH.

Background: Data on exercise pulmonary hemodynamics in healthy people and patients with pulmonary hypertension (PH) are rare. We analyzed exercise right heart catheterization (RHC) data in a symptomatic collective referred with suspected PH to characterize the differential response by diagnostic groups, to correlate resting with exercise hemodynamics, and to evaluate safety. Methods: This is a retrospective single-center study reviewing data from patients in whom an exercise RHC was performed between January 2006 and January 2013. Patients with follow-up RHC under PH -therapy were excluded. Results: Data from 101 patients were analyzed, none of them had an adverse event. In 35% we detected a resting PH (27.8% precapillary, 6.9% postcapillary). Exercise PH (mean pulmonary arterial pressure (mPAP) >30 mmHg at exercise) was found in 38.6%, whereas in 25.7% PH was excluded. We found a remarkable number of exercise PH in scleroderma patients, the majority being postcapillary. 83% of patients with mPAP-values between 20 and 24.9 mmHg at rest had exercise PH. Patients with resting PH had worse hemodynamics and were older compared with exercise PH ones. Conclusion: In this real-life experience in symptomatic patients undergoing exercise RHC for suspected PH, we found that exercise RHC is safe. The facts that the vast majority of patients with mPAP-values between 20 and 24.9 mmHg at rest had exercise PH and the older age of patients with resting PH may indicate that exercise PH is a precursor of resting PH. Whether earlier treatment start in patients with exercise PH would stabilize the disease should be addressed in future studies.

Various parameters reflecting right heart size, right ventricular function and capacitance have been shown to be prognostically important in patients with pulmonary hypertension (PH). In the advanced disease, patients suffer from right heart failure, which is a main reason for an impaired prognosis. Right heart size has shown to be associated with right ventricular function and reserve and is correlated with prognosis in patients with PH. Right ventricular reserve, defined as the ability of the ventricle to adjust to exercise or pharmacologic stress, is expressed by various parameters, which may be determined invasively by right heart catheterization or by stress-Doppler-echocardiography as a noninvasive approach. As the term “right ventricular contractile reserve” may be misleading, “right ventricular output reserve” seems desirable as a preferred term of increase in cardiac output during exercise. Both right heart size and right ventricular reserve have been shown to be of prognostic importance and may therefore be useful for risk assessment in patients with pulmonary hypertension. In this article we aim to display different aspects of right heart size and right ventricular reserve and their prognostic role in PH.

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.
