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.

Background: A new grading of tricuspid regurgitation (TR) beyond severe has been proposed. However, few studies assessing the validity of such a new grading scheme of TR have been conducted. Therefore, we evaluated associations of TR grades beyond severe with patient outcome and hemodynamics. Methods: We retrospectively studied patients who underwent 2-dimensional echocardiography and were diagnosed with severe TR between January 2014 and December 2015. According to the vena contracta width of TR (VC), the patients were classified into 2 groups: VC under 14 mm (VC<14 mm) and VC 14 mm or greater (VC≥14 mm). Hemodynamic parameters were estimated by echocardiography and were obtained by right heart catheterization. Cardiovascular events were defined as cardiovascular death or admission for heart failure. Results: A total of 679 patients (mean 72±17 years, 56% women) were included. During follow-up (median, 158 days; range, 29–891), 210 patients experienced cardiovascular events. By multivariate analysis, VC≥14 mm and left ventricular ejection fraction were independent predictors of cardiovascular events (hazard ratio, 1.57 [1.06–2.33]; hazard ratio, 0.99 [0.98–0.99], respectively). Patients with VC≥14 mm had significantly lower cardiac index (median, 1.8 versus 2.1 L/min per m 2 , P =0.001) and a higher prevalence of right atrial pressure 15 mm Hg (74% versus 60%, P <0.001) on echocardiography. Also, right heart catheterization confirmed higher right atrial pressure in patients with VC≥14 mm than those with VC<14 mm (16±8 versus 12±6 mm Hg, P =0.004). The new subset classification developed by cardiac index and right atrial pressure both on echocardiography predicted cardiovascular events (Log-rank P <0.001). Conclusions: The relationship of VC≥14 mm to adverse outcome and poor hemodynamics showed the clinical relevance and need of a new grading system beyond severe. The new hemodynamic subset classification provides additional prognostic value for cardiovascular events in patients with severe TR.

Introduction: Accurate intravascular volume status assessment is central to heart failure management, but current non-invasive bedside techniques remain a challenge. Visual inspection of jugular venous pulsation (JVP) is used as a surrogate for central venous pressure (CVP). Studies have shown variability and inaccuracy of the JVP exam in estimating CVP or right atrial pressure (RAP). Published methods of RAP estimation through internal jugular vein (IJV) ultrasonography are either complex or require offline analysis. We validated a simplified approach to ultrasonography of the JVP (uJVP) as a method to predict RAP. Methods: Adult patients undergoing right heart catheterization (RHC) were enrolled prior for IJV imaging with point of care ultrasound (POCUS) device, Butterfly iQ™. The IJV was identified on ultrasound with the patient reclined (head of bed between 30-45°) and followed cranially until tapering smaller than the adjacent carotid artery throughout the entirety of the respiratory cycle. The height of this collapse point from the sternal angle added to 5 centimeters was defined as ultrasound JVP (uJVP). Results: 77 participants underwent uJVP assessment on the same day prior to RHC. Average BMI was 33 kg/m 2 . The area under the curve (AUC) of uJVP and RAP greater than 10mmHg on RHC was 0.879 (95% CI 0.759-0.931, p<0.001), with AUC of 0.972 and 0.818 for non-obese and obese subgroups respectively, and AUC of 0.876 for elevated RAP and pulmonary capillary wedge pressure (PCWP). A uJVP cutoff of 9 or higher was 85% sensitive and 72% specific at identifying RAP greater than 10mmHg. Conclusion: We developed and validated a novel technique identifying the uJVP using POCUS which correlates with invasive RAP regardless of obesity. This technique predicted combined elevated left and right sided intracardiac pressures. The uJVP’s potential to enhance the diagnostic value of the bed-side examination in an increasingly obese heart failure population warrants further research.

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.

Introduction: The pulmonary artery pulsatility index (PAPi), calculated from the ratio of pulmonary artery pulse pressure to right atrial pressure, was initially described as a novel predictor of right ventricular failure after inferior myocardial infarction or left ventricular assist device implantation. Whether PAPi is associated with adverse outcomes in broader samples is unknown. Hypothesis: A lower PAPi is associated with mortality in a broad population referred for right heart catheterization. Methods: We examined consecutive patients undergoing right heart catheterization between 2005-2016 in a hospital-based cohort. The following exclusion criteria were applied: shock or cardiac arrest within 24 hours of catheterization, presence of mechanical circulatory support, prior cardiac transplant, prior valvular surgery, or those with missing key clinical covariates. Multivariable Cox models were utilized to examine the association between PAPi and mortality. Analyses were adjusted for age, sex, BMI, hypertension, diabetes, prior myocardial infarction, and prior heart failure. Results: We studied 8559 patients with mean age 63 years and 40% women. We found that patients in the lowest quartile of PAPi were younger, with greater proportion of men, and higher BMI, yet similar NT-proBNP compared with other quartiles ( Table 1 ). Over 12.5 years of follow-up, there were 2441 death events. Patients in the lowest PAPi quartile had a 31% greater risk of death compared with the highest quartile (multivariable adjusted HR 1.31, 95% CI 1.15-1.48, p<0.001), whereas no differences in survival were seen among individuals in quartile 2 or 3 (p>0.05 vs quartile 4 for both). Conclusions: Patients in the lowest PAPi quartile had a 31% increased risk of all-cause mortality in a broad population referred for right heart catheterization. These findings highlight a potential role for PAPi in identifying high-risk individuals across a spectrum of disease.

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.

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.

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 Introduction Since the mid-1970s, the diagnosis of acute cellular rejection (ACR) has been made by endomyocardial biopsy (EMB). Whether B-Type Natriuretic Peptide (BNP), transthoracic echocardiography (TTE) parameters and right heart catheterization (RHC) parameters can detect rejection in heart transplant (HT) patients have yielded conflicting results and did not overcome the use of EMB in the first year after HT. Purpose The aim of this study was to evaluate whether BNP, TTE and RHC parameters can be used to detect ACR in the first year after HT. Methods Prospective study of consecutive EMB performed in the first year after HT. Plasma BNP levels, TTE and RHC were performed at the same day. Clinical significant ACR was defined as ≥ 2R, according to the ISHLT 2004 grading. The area under the curve (AUC) was analysed for statistically significant associations to detect ACR. Results From 2017 to 2018, 50 EMB were performed with the following results: 2R - 5 (10.0%); 1R- 29 (58.0%); 0 – 16 (32%). Mean age was 48.7 ± 8.3 years, with mean BNP value of 964.4 ± 1114.7pg/ml. AUC results of BNP and several TTE and RHC parameters for the prediction of ACR are represented in the table. Right atrial pressure (RAP) value (p = 0.027) was the only significantly predictor of ACR, while isovolumic relaxation time measured by TTE revealed a borderline significant trend (p = 0.076). RAP &gt; 10mmHg had a sensitivity of 60.0% and a specificity of 84.4% for detecting ACR. Conclusion Detecting ACR without EMB remains a clinical challenge, but RAP measured by RHC was a significant predictor of ACR in the first year after HT, while BNP values did not correlate with ACR. AUC values PARAMETERS AUC p 95% CI BNP 0.658 0.251 0.405-0.911 Troponin I 0.591 0.507 0.260-0.923 Left ventricular ejection fraction 0.416 0.541 0.218-0.614 E/A 0.480 0.895 0.282-0.678 Deceleration time 0.463 0.463 0.161-0.765 Isovolumic relaxion time 0.745 0.076 0.427-1.000 Cardiac index 0.595 0.488 0.346-0.845 Pulmonary capillary wedge pressure 0.628 0.401 0.329-0.926 Mean pulmonary artery pressure 0.684 0.181 0.511-0.857 Right atrial pressure 0.804 0.027 0.631-0.978 AUC values

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 (+ 1.4 mmHg; 95% limits of agreement + 25 to − 22 mmHg) and PA mean pressures (+ 1.4 mmHg; 95% limits of agreement + 19 to − 16 mmHg). 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.
