Abstract Funding Acknowledgements Type of funding sources: None. Background. Symptomatic rheumatic mitral stenosis (MS) results in elevation in left atrial (LA) pressure that is passively transmitted to derange pulmonary hemodynamics and subsequently elevate right ventricular afterload. We studied associations between LA to right atrial reservoir strain ratio (LA-RAs) and invasive pulmonary hemodynamics in addition to the ratio’s ability to identify subjects with elevated pulmonary vascular resistance (PVR). Methods.  Consecutive MS subjects undergoing right heart catheterization (RHC) and percutaneous transvenous mitral commissurotomy (PTMC) were enrolled. Subjects with atrial fibrillation, >mild mitral regurgitation, concomitant aortic valve or ischemic heart disease were excluded. LA-RAs was assessed by speckle-tracking echocardiography and stratified into high or low LA-RAs subgroups based on mean value. Correlations with invasive pulmonary hemodynamics was studied. ROC analysis was performed to identify pulmonary hypertension (PH) and PVR > 3 Wood Units. Results. 110 subjects were analysed (age: 32 ± 8; 72% female). LA and RA reservoir strain was feasible in 88 (80%) and 83 (75%) subjects respectively. Patients with low LA-RAs demonstrated more severe MS (0.8 ± 0.1 vs. 1.0 ± 0.2cm2), higher mean pulmonary artery (43 ± 13 vs. 33 ± 13mmHg) and capillary wedge pressure (28 ± 6 vs.23 ± 16mmHg) as compared with high LA-RAs (p < 0.001 for all). LA-RAs was associated with invasive PA systolic (r=-0.30;p = 0.05), diastolic (r=-0.28;p = 0.02) and mean (r=-0.33; p = 0.002) pressures, demonstrated modest ability to identify elevated PVR (AUC = 0.65;p = 0.03) and strong ability to identify PH (AUC = 0.75; p < 0.001). LA-RAs significantly increased after PTMC (0.43 ± 0.1 to 0.52 ± 0.1;p < 0.001). Conclusions. The novel atrial strain ratio is associated with measures of invasive pulmonary hemodynamics and demonstrates ability to identify PH and elevated PVR in MS.

Abstract Background Systolic pulmonary artery pressure (SPAP) can be estimated non-invasively as the sum of indices for right atrial (RA) pressure and tricuspid regurgitation (TR) pressure gradient. Although echocardiographic evaluation of inferior vena cava diameter and collapsibility is currently being used to estimate RA pressure (IVC method), RA strain may be an alternative since atrial strain is related to atrial pressure. Objective We tested if RA strain by speckle tracking echocardiography can be used as a surrogate of mean RA pressure (RA strain method), and by adding the TR pressure gradient, be used to estimate SPAP. Methods We retrospectively analyzed 91 patients (mean age, 58 years) referred to right heart catheterization due to unexplained dyspnea or suspected pulmonary hypertension. Echocardiography was performed within 24 hours of the invasive procedure. RA reservoir strain was calculated from apical four-chamber view. SPAP was calculated as the sum of peak TR pressure gradient and estimated RA pressure by the IVC or RA strain methods. Results Right heart catheterization showed SPAP and mean RA pressures of 51±20 mmHg and 9±6 mmHg, respectively. RA reservoir strain was inversely correlated with mean RA pressure (r=−0.61, p<0.01). Thus, we set mean RA pressure as 5, 10 and 15 mmHg depending on high (≥25%), middle (10–25%) and low (≤10%) values of RA reservoir strain. As shown in the figure, both the RA strain and IVC methods when combined with peak TR velocity, provided good estimates of invasively measured SPAP. Conclusions RA strain provides a semiquantitative measure of RA pressure, which can be used in combination with peak TR velocity to estimate SPAP. This approach can be used as an alternative when the IVC method is not available in cases with poor subcostal window.

Objective To determine if plasma exosomal microRNAs (miRNAs) can predict survival in patients with idiopathic pulmonary arterial hypertension (IPAH). Methods The study enrolled patients with IPAH that underwent right heart catheterization. Plasma was collected and exosomal miRNAs were extracted. Exosomes were evaluated using transmission electron microscopy, Western blot analysis and particle size distribution analysis. MiRNAs were evaluated using a miRNA microarray and validated using real-time polymerase chain reaction. Results This study included 12 patients with IPAH in the study group and 48 patients with IPAH in the validation group. The mean ± SD follow-up duration was 60.3 ± 35.4 months in the overall cohort. The levels of miR-596 were higher in the nonsurvivors compared with the survivors. The levels of miR-596 significantly correlated with survival time, mean right atrial pressure, pulmonary vascular resistance (PVR) and cardiac index. High levels of miR-596 and PVR were significantly associated with poor overall survival. Multivariate analysis demonstrated that exosomal miR-596 (hazard ratio [HR] = 2.119; 95% confidence interval [CI] 1.402, 3.203) and PVR (HR = 1.146; 95% CI 1.010, 1.300) were independent predictors of survival. Conclusions High levels of plasma exosomal miR-596 were significantly associated with disease severity and poor prognosis of patients with IPAH.

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.

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. The visual inspection of jugular venous pulsation (JVP) in a reclined position and measuring its height from the sternal notch has been used as a surrogate for right atrial pressure (RAP). There are no studies on the predictive value of a visible internal jugular vein (IJV) in the upright position (U 2 JVP). Hypothesis: Point of care ultrasound (POCUS) for volume assessment in the upright position is predictive of clinically significant hypervolemia. 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 and its size in comparison to the carotid artery was identified on ultrasound with the patient upright. Elevated RAP and PCWP was present if the IJV was still visible and not collapsed throughout the entirety of the respiratory cycle. Valsalva was used to confirm the position of a collapsed IJV. Results: 72 participants underwent U 2 JVP assessment on the same day prior to RHC. Average BMI was 31.9 kg/m2. The area under the curve (AUC) of U 2 JVP predicting RAP greater than 10 mmHg and PCWP of 15 mmhg or higher on RHC was 0.78 (95% CI 0.66-0.9, p<0.001), with AUC of 0.86 and 0.74 for non-obese and obese subgroups respectively, p= 0.38. The finding of a visible U 2 JVP in the upright position was 70.6 % sensitive and 85.5 % specific with a negative predictive value of 90.4% for identifying both RAP greater than 10 mmHg and PCWP equal or greater than 15 mmHg. Conclusions: The U 2 JVP is novel and pragmatic bed-side approach to the assessment of clinically significant elevated intra-cardiac pressures in our increasingly obese heart failure population.

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.

BackgroundPulmonary hypertension (PH/PAH) can have many possible causes in childhood. The aim of the COMPERA registry is the characterization of patients of all ages with PH/PAH and their treatment patterns.MethodsSince June 2013, paediatric patients can be included in the COMPERA registry (ClinTrials.gov: NCT01347216) which has originally been established for adult patients with pulmonary hypertension in 2007.ResultsUntil 2015, 78 patients <18 years (47 Pat <6 years) with pulmonary hypertension were enrolled, of whom 65.4% had PAH due to congenital heart disease (PAH-CHD), 25.6% had idiopathic PAH (iPAH), 3 had persistent PH of the newborn, 2 had PH associated with interstitial lung disease, and two had other PH. The patients were 6.1±6.0 years old, 52.6% girls; NYHA functional class I/II in 55.0%, and III in 42.3%. Mean disease duration after diagnosis was 37.7±55.8 months. Right heart catheterization data were available for 82.1% of the patients. Mean pulmonary artery pressure was 42.8±19.4 mmHg, right atrial pressure was 8.0±8.8 mmHg, cardiac index was 3.6±1.2 l/min/m2. Monotherapy was received by 65.4% of the patients whereas 33.4% of the patients had combination therapy. Phosphodiesterase-5 inhibitors (PDE5I) were administered to 76.9% of the patients, 35.9% of the patients received endothelin receptor antagonists and 3.8% received prostacyclins. About 24% of patients received anticoagulation therapy.ConclusionThe most common form of PH in this study cohort is PAH-CHD, followed by iPAH. Treatment options for children primarily comprise PDE5I. Only a small number of paediatric patients receive anticoagulation therapy.

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.
