Abstract
OBJECTIVES Ultrasonography is an essential examination performed in various clinical fields. The number of clinical sonographers has been increasing. However, the working environments and conditions at each facility are different, leading to diverse problems. Among them, the emerging issue is the sexual disagreement between the sonographer and patient at the time of echocardiography. Since the patient must expose their breast during echocardiography, female patients may refuse to undergo the examination when conducted by a male sonographer. This study aimed to conduct a questionnaire survey to understand the measures for sonographer-patient gender mismatch at different facilities. METHODS A questionnaire on the implementation of echocardiography by male sonographers for female patients was answered by representatives and specialist technicians of the Japanese Society of Echocardiography. RESULTS Questionnaire responses were obtained from 50 facilities (59 participants). A total of 70% of the facilities restricted male sonographers from conducting echocardiography examinations for female patients. Among them, 81% of the facilities serviced female patients aged 60 years or younger. CONCLUSIONS It has become clear that the gender selection of echocardiographic examiners varies from facility to facility, and providing a sufficient explanation before echocardiographic examination is necessary to avoid causing uncomfortable situations for female patients.

Abstract
INTRODUCTION There is no consensus on the adjustment of home oxygen therapy (HOT) and pulmonary hypertension (PH)-specific medications after balloon pulmonary angioplasty (BPA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH). We aimed to examine the status of de-escalation/discontinuation of HOT and PH-specific medications post-BPA and clarify its effect on hemodynamics, biomarkers, and long-term outcomes. METHODS AND RESULTS From November 2012 to May 2018, 135 consecutive CTEPH patients who underwent BPA at a single university hospital were enrolled (age, 63.5 ± 13.5 years; World Health Organization functional class [WHO-FC] II/III/IV, 34/92/9). The mean pulmonary arterial pressure decreased from 37.7 ± 11.3 to 20.4 ± 5.1 mmHg 1-year post-BPA (p<0.01). The proportion of patients who required HOT and combination medical therapy (≥2 PH-specific medications) decreased 1-year post-BPA (from 58.5% to 7.4% and from 40.0% to 10.4%, respectively). Baseline factors influencing the requirement of HOT and combination medical therapy post-BPA were almost identical (i.e., lower exercise capacity and pulmonary diffusion capacity, and worse hemodynamics). Regardless of their discontinuation, the improved hemodynamics, functional capacity (WHO-FC), and biomarkers (B-type natriuretic peptide and high-sensitivity troponin T) were almost maintained, and no adverse 1-year clinical outcomes (all-cause death and PH-related hospitalization) were observed. CONCLUSIONS Most CTEPH patients discontinued HOT and PH-specific combination medical therapy post-BPA, which was not associated with the deterioration of hemodynamics, functional capacity, or biomarkers. No long-term adverse outcomes were observed.

Abstract
BACKGROUND Treatment options for patients with chronic thromboembolic pulmonary hypertension ineligible for pulmonary endarterectomy (inoperable CTEPH) include balloon pulmonary angioplasty (BPA) and riociguat. However, these two treatment options have not been compared prospectively. We aimed to compare the safety and efficacy of BPA and riociguat in patients with inoperable CTEPH. METHODS This open-label, randomised controlled trial was conducted at four high-volume CTEPH centres in Japan. Patients aged 20-80 years with inoperable CTEPH (mean pulmonary arterial pressure ≥25 to <60 mm Hg and pulmonary artery wedge pressure ≤15 mm Hg) and WHO functional class II or III were randomly assigned (1:1) to BPA or riociguat via a computer program located at the registration centre using a minimisation method with biased-coin assignment. In the BPA group, the aim was for BPA to be completed within 4 months of the initial date of the first procedure. BPA was repeated until mean pulmonary arterial pressure decreased to less than 25 mm Hg. The frequency of BPA procedures depended on the difficulty and number of the lesions. In the riociguat group, 1·0 mg riociguat was administered orally thrice daily. When the systolic blood pressure was maintained at 95 mm Hg or higher, the dose was increased by 0·5 mg every 2 weeks up to a maximum of 2·5 mg thrice daily; dose adjustment was completed within 4 months of the date of the first dose. The primary endpoint was change in mean pulmonary arterial pressure from baseline to 12 months, measured in the full analysis set (patients who were enrolled and randomly assigned to one of the study treatments, and had at least one assessment after randomisation). BPA-related complications and indices related to clinical worsening were recorded throughout the study period. Adverse events were recorded throughout the study period and evaluated in the safety analysis set (patients who were enrolled and randomely assigned to one of the study treatments, and had received part of or all the study treatments). This trial is registered in the Japan Registry of Clinical Trials (jRCT; jRCTs031180239) and is completed. FINDINGS Between Jan 8, 2016, and Oct 31, 2019, 61 patients with inoperable CTEPH were enrolled and randomly assigned to BPA (n=32) or riociguat (n=29). Patients in the BPA group underwent an average of 4·7 (SD 1·6) BPA procedures. In the riociguat group, the mean maintenance dose was 7·0 (SD 1·0) mg/day at 12 months. At 12 months, mean pulmonary arterial pressure had improved by -16·3 (SE 1·6) mm Hg in the BPA group and -7·0 (1·5) mm Hg in the riociguat group (group difference -9·3 mm Hg [95% CI -12·7 to -5·9]; p<0·0001). A case of clinical worsening of pulmonary hypertension occurred in the riociguat group, whereas none occurred in the BPA group. The most common adverse event was haemosputum, haemoptysis, or pulmonary haemorrhage, affecting 14 patients (44%) in the BPA group and one (4%) in the riociguat group. In 147 BPA procedures done in 31 patients, BPA-related complications were observed in 17 procedures (12%) in eight patients (26%). INTERPRETATION Compared with riociguat, BPA was associated with a greater improvement in mean pulmonary arterial pressure in patients with inoperable CTEPH at 12 months, although procedure-related complications were reported. These findings support BPA as a reasonable option for inoperable CTEPH in centres with experienced BPA operators, with attention to procedure-related complications. FUNDING Bayer Yakuhin.

Abstract
BackgroundThe SARS-CoV-2 messenger RNA (mRNA) vaccines BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna) have benefitted all countries amid the coronavirus disease 2019 (COVID-19) crisis. Whereas both of them have shown efficacy in preventing COVID-19 illness in healthy participants, there is paucity of data about immunogenicity and safety of mRNA COVID-19 vaccines in patients with autoimmune, inflammatory rheumatic disease. Recent observational studies evaluated mainly BNT162b2, suggesting that glucocorticoids, immunosuppressive agents impair SARS-CoV-2 vaccine responses. However, difference in immune reactions and safety between BNT162b2 and mRNA-1273 have not been clarified in patients with inflammatory rheumatic diseases.ObjectivesTo assess humoral and T cell immune responses and safety profiles after two doses of different mRNA vaccine against SARS-CoV-2; BNT162b2 and mRNA-1273.MethodsWe enrolled consecutive, previously uninfected patients with inflammatory rheumatic diseases receiving mRNA vaccine including BNT162b2 and mRNA-1273. Healthy participants receiving BNT162b2 were also recruited as control. Blood samples were obtained 3weeks, 2 months, 3 months, 4 months, and 6 months after second dose of vaccines. We measured titres of neutralizing antibodies against SARS-CoV-2 and calculated seroconversion rates to evaluate humoral responses. We also assessed T-cell immunity responses by using interferon releasing assay against SARS-CoV-2 in a part of the patients. Answers to questionnaires about adverse reactions were obtained from participants.ResultsA total of 974 patients with inflammatory rheumatic diseases and healthy 630 control participants were enrolled. Among them, 796 patients received BNT162b2, 178 patients received mRNA-1273, and all control participants received BNT162b2. Seroconversion rates and neutralizing antibody titres 3 weeks after vaccination were significantly higher in patients with mRNA-1273 and healthy participants with BNT162b2 compared with patients with BNT162b2; seroconversion rates, 97.2% vs 99.5% vs 83.3%, p<0.001; titers of neutralizing antibodies, 29.4±33.9 IU/mL vs 23.9±14.2 IU/mL vs 10.8±16.5 IU/mL, p<0.001, respectively. On another front, T cell reaction against SARS-CoV-2 was similar in both patients with mRNA-1273 and BNT162b2; interferon gamma levels for antigen 1, 1.2±2.1 IU/mL vs 0.8±2.5 IU/mL, p=0.23; and for antigen 2, 1.4±1.9 IU/mL vs 1.0±2.1 IU/mL, p=0.11, respectively. Regarding adverse reaction of each mRNA vaccine, the frequency of systemic adverse reactions including fever and general fatigue are also significantly higher in patients with mRNA-1273 and healthy controls than patients with BNT162b2; fever, 48.0% vs 44.9% vs 10.2%, p<0.001; general fatigue, 70.4% vs 61.8% vs 31.2%, p<0.001, respectively). In longitudinal measurement, neutralizing antibody titres in patients with BNT162b2 were decreased more rapidly than those in healthy controls; 3.3±3.2 IU/mL in patients with BNT162b2 at 4 months and 3.2±4.7 IU/mL in healthy controls with BNT162b2 at 6 months. We identified age, glucocorticoid dose (prednisolone > 7.5mg), use of immunosuppressants including methotrexate, mycophenolate, cyclophosphamide, and tacrolimus are associated with rapid attenuation of humoral responses in patients with BNT162b2.ConclusionOur results demonstrated a significant higher humoral immunogenicity and frequency of systemic adverse reaction of the SARS-CoV-2 mRNA-1273 (Moderna) compared with the BNT162b2 (Pfizer-BioNTech) in inflammatory rheumatic disease patients. Glucocorticoid and immunosuppressive agents impaired induction and sustention of neutralizing antibody, and earlier third booster vaccination may be required within 4 months, especially for those receiving BNT162b2.References[1]Steensels D, Pierlet N, Penders J et al.

Abstract
BACKGROUND Riociguat is a soluble guanylate cyclase stimulator that improves hemodynamics in patients with pulmonary hypertension (PH). Accumulating evidence implicates the additional effect of riociguat on the increase in cardiac output. However, its mechanisms have not been fully understood. This study aimed to investigate whether riociguat could ameliorate right ventricular (RV) contraction as well as hemodynamics. METHODS We studied 45 patients with pulmonary arterial hypertension (14) or chronic thromboembolic pulmonary hypertension (31) and evaluated hemodynamics, using right-sided heart catheterization, before and after the administration of riociguat. RV function was assessed by echocardiography, including speckle-tracking echocardiography. RESULTS Riociguat significantly improved the WHO functional class and reduced the mean pulmonary arterial pressure and vascular resistance. In addition, the cardiac index increased. RV remodeling was ameliorated after riociguat administration as assessed by the echocardiographic parameters, such as RV diameter and RV area index. RV function, including RV fractional area change and RV global longitudinal strain, also significantly improved, and their improvement was even observed in patients with mild PH after pulmonary endarterectomy or balloon pulmonary angioplasty. Furthermore, covariance analysis revealed that RV global longitudinal strain and RV fractional area change improved after riociguat administration, even with the same mean pulmonary arterial pressure, implicating the improvement of RV contractile function by riociguat, regardless of RV loading. CONCLUSIONS Riociguat not only improved the hemodynamics of patients with PH but also ameliorated the echocardiographic parameters with RV function. RV strain could detect the subtle improvement in mild PH, and riociguat may have a benefit even after intervention, as assessed by speckle-tracking echocardiography.

Abstract
Background Right ventricular (RV) dysfunction is a prognostic factor for cardiovascular disease. However, its mechanism and pathophysiology remain unknown. We investigated RV function using RV‐specific 3‐dimensional (3D)‐speckle‐tracking echocardiography (STE) in patients with chronic thromboembolic pulmonary hypertension. We also assessed regional wall motion abnormalities in the RV and chronological changes during balloon pulmonary angioplasty (BPA). Methods and Results Twenty‐nine patients with chronic thromboembolic pulmonary hypertension who underwent BPA were enrolled and underwent right heart catheterization and echocardiography before, immediately after, and 6 months after BPA. Echocardiographic assessment of RV function included both 2‐dimensional‐STE and RV‐specific 3D‐STE. Before BPA, global area change ratio measured by 3D‐STE was significantly associated with invasively measured mean pulmonary artery pressure and pulmonary vascular resistance (r=0.671 and r=0.700, respectively). Dividing the RV into the inlet, apex, and outlet, inlet area change ratio showed strong correlation with mean pulmonary artery pressure and pulmonary vascular resistance before BPA (r=0.573 and r=0.666, respectively). Only outlet area change ratio was significantly correlated with troponin T values at 6 months after BPA (r=0.470), and its improvement after BPA was delayed compared with the inlet and apex regions. Patients with poor outlet area change ratio were associated with a delay in RV reverse remodeling after treatment. Conclusions RV‐specific 3D‐STE analysis revealed that 3D RV parameters were novel useful indicators for assessing RV function and hemodynamics in pulmonary hypertension and that each regional RV portion presents a unique response to hemodynamic changes during treatment, implicating that evaluation of RV regional functions might lead to a new guide for treatment strategies.

Abstract
Abstract
Introduction
Balloon pulmonary angioplasty (BPA) has been reported as an effective and safe treatment for patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, its safety and efficacy in elderly patients remains unknown.
Purpose
We investigated the effect of BPA on hemodynamics and respiratory parameters, functional capacity, and short- and long-term outcome in elderly patients.
Methods
From November 2012 to May 2018, 141 consecutive CTEPH patients who underwent BPA in a single university hospital were enrolled (age: 65 [54.5–74] years old, WHO functional class [WHO-FC] II/III/IV; 35/96/10). Patients were divided into two groups according to the age; elderly (≥75 years, N=32) and young groups (<75 years, N=109). Hemodynamics (right-sided heart catheterization), biomarkers (brain natriuretic peptide), respiratory function (spirometry and diffusion capacity measurement), and functional capacity (6-minute walk distance [6MWD] and WHO-FC) were evaluated at baseline and 1-year post BPA. Procedure-related complications (in hospital death, use of percutaneous cardiopulmonary support [PCPS], and pulmonary injury) and all cause death during the follow up period were also assessed.
Results
At baseline, although elderly group had less severe hemodynamics (mPAP: 33.1±6.7 vs 39.0±11.8 mmHg, p<0.05), they had poor exercise capacity and reduced pulmonary diffusion capacity, compared with young group (6MWD: 264.6±101.3 vs 369.7±105.2 m, %DLco: 42.0±12.0 vs 50.2±12.7%, all p<0.05). BPA improved hemodynamics, biomarkers, exercise capacity, and pulmonary diffusion capacity in both elderly and young groups (all p<0.05). There was no in-hospital death or use of PCPS in both groups, although the incidence of pulmonary injury was higher in elderly group (14.3% vs 5.3%, p<0.01). Under the normalized hemodynamics 1-year after BPA in both groups, exercise capacity and pulmonary diffusion capacity were worse in the elderly group than young groups (p<0.01). The incidence of all-cause death in the follow up period was higher in elderly group, all of which were due to non-pulmonary hypertension (PH)-related death (p<0.01).
Conclusion
BPA was effective in improving hemodynamics and respiratory parameters and functional capacity, in associated with no critical complication, regardless of the age. Elderly patients who were treated with BPA were associated with higher incidence of non-PH-related death.

Abstract
AIMS Balloon pulmonary angioplasty (BPA) improves hemodynamics and exercise tolerance in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, its diagnostic and predictive values remain unclear. We investigated the diagnostic and predictive values of BPA by assessing the mechanism of right ventricular (RV) dysfunction. METHODS AND RESULTS Hemodynamic improvement was maintained over 6 months in 99 patients with CTEPH who underwent BPA. Notably, 57 of 99 patients showed normalization of pulmonary vascular resistance (PVR) after BPA. The RV mid free wall longitudinal strain (RVMFS) was inversely correlated with the 6-min walk distance (r = -.35, P = .01) and serum levels of high-sensitivity cardiac troponin T (hs-cTNT) (r = -.39, P = .004) 6 months post-BPA in the PVR-normalized group. Among all variables analyzed, only the pre-BPA RVMFS was correlated with the post-BPA RVMFS (r = .40, P = .001), and the pre-BPA RVMFS (<-15.8%) was the strongest predictor of post-BPA normalization of RVMFS (area under the curve 0.80, P = .01, sensitivity 89%, and specificity 63%). The immediate post-BPA RVMFS showed worsening over 6 months after the procedure (-25.8% to -21.1%) in patients with high serum hs-cTNT levels (>0.0014 ng/mL). In contrast, we observed an improvement in these values in those with low serum hs-cTNT levels (-23.6% to -24.4%). CONCLUSION RVMFS of -15.8% may be a useful cutoff value to categorize the refractory and non-refractory stages of disease. Sustained serum hs-cTNT elevation post-BPA indicates subclinical RV myocardial injury, with resultant RVMFS deterioration and poor exercise tolerance.

Abstract
Background Pulmonary hypertension (PH) is a major comorbidity of chronic obstructive pulmonary disease (COPD). However, the association of PH detected by echocardiography and COPD-related outcome in longitudinal follow-up has not been elucidated. In this study, we aimed to investigate the relationship between clinical characteristics of COPD patients with PH detected by echocardiography and various outcome parameters such as COPD exacerbation and health status over a three-year observation period. Methods In this observational study, we analyzed patients with COPD who underwent chest computed tomography and echocardiography at baseline (n = 183). Results The prevalence of PH was 21.9% (40 patients). The median estimated systolic pulmonary artery pressure in patients with PH was 38.8 mmHg. COPD patients with PH were older, had a lower body mass index, scored worse in the COPD Assessment Test and St. George's Respiratory Questionnaire, and exhibited a lower diffusing capacity of the lung for carbon monoxide in comparison to patients without PH. In computed tomography images, the percentages of low-attenuation areas (LAA%) and interstitial abnormalities were higher in COPD patients with PH than in those without PH. Higher values for LAA% (LAA ≥ 30%) and interstitial abnormalities independently increased the risk of PH. The ratio of main pulmonary diameter to aortic artery diameter was significantly correlated with estimated systolic pulmonary artery pressure. In the follow-up analysis, the frequency of exacerbations in three years was significantly higher in patients with PH compared to patients without PH. Conclusion In this study, we identified the clinical characteristics of COPD patients with PH detected by echocardiography. The presence of PH assessed by echocardiography was related to future COPD exacerbations and closely related to radiographical emphysema.

Abstract
OBJECTIVES To explore the outcome of monochorionic monoamniotic (MCMA) twin pregnancies affected by twin-to-twin transfusion syndrome (TTTS). METHODS MEDLINE and EMBASE databases were searched for studies reporting the outcome of MCMA twin pregnancies complicated by TTTS. The primary outcome was intrauterine death (IUD); secondary outcomes were miscarriage, single IUD, double IUD, neonatal death (NND), perinatal death (PND), survival of at least one twin, survival of both twins and preterm birth (PTB) before 32 weeks' gestation. Outcomes were assessed in MCMA twins affected by TTTS not undergoing intervention and in those treated with amniodrainage, laser therapy or cord occlusion. Subgroup analysis was performed including cases diagnosed before 24 weeks. Random-effects meta-analysis of proportions was used to analyze the data. RESULTS Fifteen cohort studies, including 888 MCMA twin pregnancies, of which 44 were affected by TTTS, were included in the review. There was no randomized trial comparing the different management options in MCMA twin pregnancies complicated by TTTS. In cases not undergoing intervention, miscarriage occurred in 11.0% of fetuses, while the incidence of IUD, NND and PND was 25.2%, 12.2% and 31.2%, respectively. PTB complicated 50.5% of these pregnancies. In cases treated by laser surgery, the incidence of miscarriage, IUD, NND and PND was 19.6%, 27.4%, 7.4% and 35.9%, respectively, and the incidence of PTB before 32 weeks' gestation was 64.9%. In cases treated with amniodrainage, the incidence of IUD, NND and PND was 31.3%, 13.5% and 45.7% respectively, and PTB complicated 76.2% of these pregnancies. Analysis of cases undergoing cord occlusion was affected by the very small number of included cases. Miscarriage occurred in 19.2%, while there was no case of IUD or NND of the surviving twin. PTB before 32 weeks occurred in 50.0% of these cases. CONCLUSIONS MCMA twin pregnancies complicated by TTTS are at high risk of perinatal mortality and PTB. Further studies are needed in order to elucidate the optimal type of prenatal treatment in these pregnancies. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
Transcatheter aortic valve implantation (TAVI) is widely accepted as an alternative to surgical aortic valve replacement (SAVR) for the treatment of severe aortic stenosis (AS). Existing scientific evidence demonstrates that TAVI is superior to SAVR, and it is expected that indications for the clinical applications of TAVI will be expanded in the future. Echocardiography plays a key role in perioperative assessment of patients undergoing TAVI. Preprocedural echocardiographic evaluation is important to determine the severity of AS in addition to patients' anatomical suitability for TAVI. Furthermore, echocardiography is essential for intraoperative guidance, assessment of complications, postoperative evaluation, and prognostic prediction. Inaccurate echocardiographic measurements and evaluation can lead to less-than-optimal/inappropriate treatment strategies in patients with AS. Therefore, a thorough understanding of the limitations of echocardiographic evaluation is important. This review summarizes the role of echocardiographic evaluation in patients undergoing TAVI.

Abstract
The aortic valve (AV) is the most commonly affected site in multiple papillary fibroelastomas, but the frequency of embolism caused by the attachment side of the AV has not been elucidated. According to the review of the previous literature, 16 cases have been found attached to the AV. Of these, 6 of these have been found to be attached on the aortic side and 4 on the left ventricular side, 1 was bilateral, and 5 cases were unknown. Of the cases found on the aortic side, embolism occurred in 3 of them, and of the left ventricular side cases, embolism occurred in 2 of them. The frequency of embolism is equivalent even if papillary fibroelastoma attached to either side of the AV.

Abstract
Background:
The prevalence, patient profile, and outcomes of sleep-disordered breathing (SDB) in aortic stenosis (AS) remain unknown, especially in East Asia. Methods and Results:
One hundred and eighty-one AS patients undergoing transcatheter aortic valve implantation (TAVI) were enrolled. Sixty-one patients (33.7%) had SDB, and lower stroke volume index was an independent determinant of SDB. Incidence of in-hospital stroke after TAVI was higher in the SDB group. Conclusions:
SDB is associated with left ventricular systolic dysfunction in Japanese AS patients referred for TAVI. SDB was highly associated with the incidence of stroke as a procedural complication.

Abstract
Aims Increased stroke volume (SV) is a prognosticator of severe aortic stenosis (AS) after transcatheter aortic valve replacement (TAVR). This study aimed to investigate preprocedural echocardiographic predictors of increased SV after TAVR. Methods and results Clinical and echocardiographic data were retrospectively analysed in 129 patients with severe AS who underwent TAVR (2013-2015). We compared the echocardiographic data and cardiac events between the decreased SV group (n=28) and the increased SV group (n=101). Univariate and multivariate analyses were used to assess the predictors of increasing SV. AS severity significantly diminished, left and right ventricular function improved, and SV index (SVi) increased after TAVR: aortic valve area index (0.46±0.13 vs. 1.18±0.33 cm2, p<0.001); aortic regurgitation (AR) grade (1.85±0.55 vs. 1.60±0.54, p<0.001); left ventricular ejection fraction (59.9±12.7 vs. 64.1±12.0%, p<0.001); right ventricular fractional area change (RVFAC) (48.8±11.9 vs. 53.3±14.0%, p<0.001); SV index (SVi) (46.7±11.0 vs. 52.8±12.0 ml/m2, p<0.001). Kaplan-Meier survival estimates suggested that the SVi increase was associated with the decreased cardiovascular events one year after TAVR (hazard ratio 4.08, 95% confidence interval [CI]: 1.32-12.7, p=0.02). On multivariate analysis, preprocedural AR grade (odds ratio [OR] 7.00, 95% CI: 2.76-17.8, p<0.001) and preprocedural RVFAC (OR 1.05, 95% CI: 1.01-1.10, p=0.011) correlated with the SV increase. Conclusions Preprocedurally, greater AR and higher RVFAC could predict an increased SVi and thus the occurrence of fewer cardiac events. Preserved preprocedural RV systolic function is crucial for an increased SV after TAVR.

Abstract
Balloon pulmonary angioplasty (BPA) has emerged as an effective treatment for patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH). Renal function has been identified as a prognostic marker in patients with pulmonary hypertension in previous studies. We, therefore, aimed to investigate the clinical parameters associated with improvements in renal function in patients with CTEPH. A total of 45 consecutive patients with inoperable CTEPH undergoing BPA (mean age 62.2 ± 15.1 years) were included in the study. We evaluated the patients' clinical characteristics at baseline and at 1-year post-BPA, and investigated the association between renal function and hemodynamic parameters, including right heart function. Hemodynamics and renal function showed sustained improvements at 1 year after BPA in 64.4% of patients. Improved estimated glomerular filtration rate (eGFR) was significantly correlated with increased cardiac index (r = 0.433, p = 0.003) and mixed venous oxygen saturation (SvO2; r = 0.459, p = 0.002), and with decreased mean pulmonary arterial pressure (r = - 0.420, p = 0.004) and pulmonary vascular resistance (r = -- 0.465, p = 0.001). Multivariate analysis revealed that an increase in SvO2 immediately after the final BPA was associated with improved eGFR after the 1st year (odds ratio 1.041; 95% confidence interval 1.004-1.078; P = 0.027). The cut-off value for predicting improved eGFR was an increase in SvO2 after the final BPA of >125.4% over the baseline value (specificity 100%, sensitivity 24.1%). In conclusion, BPA improved symptoms, right heart function, hemodynamics, and renal function up to the chronic phase. Increasing SvO2 by >125.4% above baseline in the acute phase is important for improving renal function at 1 year after BPA in CTEPH patients.

Abstract
Background Transcatheter aortic valve implantation (TAVI) is an alternative therapy for surgically high-risk patients with severe aortic stenosis (AS). Although TAVI improves survival of patients with severe AS, the mechanism of this effect remains to be clarified. We investigated the effects of TAVI on left ventricular (LV) function and identified the predictive parameters for cardiac events after TAVI. Methods and results We studied 128 patients with severe symptomatic AS who underwent TAVI. Echocardiographic assessments were performed before and after TAVI. In addition to the conventional echocardiographic parameters such as LV ejection fraction (LVEF) and LV mass index (LVMI), the LV global longitudinal strain (GLS) and early diastolic peak strain rate (SR_E) using two-dimensional speckle tracking echocardiography were also evaluated. All patients were assessed for clinical events including major adverse cardiac events and stroke according to Valve Academic Research Consortium-2 criteria. GLS, early diastolic peak velocity (eʹ), aortic regurgitation (AR) severity, and SR_E were significantly improved after TAVI. Thirteen patients had an event during the observational period of 591 days (median). Patients with events had higher LVMI, more severe AR, and worse GLS compared to those without events. Furthermore, receiver-operating curve analysis revealed that GLS was the strongest predictor for clinical events (p = 0.009; area under the curve, 0.73). Conclusion Preoperative LV geometric deformation and dysfunction, as a consequence of the cumulative burden of pressure overload, improved after TAVI and could predict cardiac events after TAVI.

Abstract
Hypertrophic cardiomyopathy (HCM) is an extremely heterogeneous genetic disease that affects the left ventricle (LV) and has a varied clinical course and phenotypic expression. Here, we report a case of two sisters with HCM who developed a massive refractory left atrial appendage (LAA) thrombus and recurrent embolism. The older sister, who was at a high surgical risk due to progressive LV systolic dysfunction with an ejection fraction of 19%, underwent LAA plication in combination with implantation of an LV assist device after progression to treatment-refractory heart failure at the age of 49. The younger sister underwent surgical thrombectomy, LAA plication, and Maze surgery before deterioration of heart failure at the age of 47. She was free from embolism and atrial fibrillation for 2years after surgery. Individualized therapeutic approaches targeting the LAA at a relatively early stage are required in the subgroups of HCM patients with left atrial dysfunction.

Abstract
We investigated the effects of paraprobiotic Lactobacillus paracasei MCC1849 (LAC-Shield™) on symptoms of the common cold and mood states in healthy young adults. A total of 241 participants were randomised to receive 1×1010 heat-killed L. paracasei MCC1849 cell powder (10LP), 3×1010 heat-killed L. paracasei MCC1849 cell powder (30LP), or placebo powder without any L. paracasei cells once daily for 12 weeks based on the incidence of the common cold in the previous year, so that the risk of the incidence was equal among the groups. The incidence and severity of common cold symptoms were rated daily in a subject diary. Salivary secretory immunoglobulin A concentrations and saliva flow rates were analysed at 0 and 6 weeks. The Profile of Mood States (POMS) was assessed using POMS 2 0, 6, and 12 weeks after the intervention. No significant differences were observed in the incidence of the common cold among the groups. In a prespecified subgroup of subjects who had the common cold in the previous year, the incidence, total number of days of symptoms, and symptom scores of the common cold significantly improved in the 10LP-intake group, and were slightly lower in the 30LP-intake group than in the placebo group. The level of deterioration in the positive mood state caused by stress was less in the MCC1849-intake group than in the placebo group. These results indicate that L. paracasei MCC1849 has the potential to improve resistance to common cold infections in susceptible subjects and maintain a desirable mood state, even under mental stress conditions. Further randomised controlled trials are needed in order to investigate the possible beneficial effects of paraprobiotic L. paracasei MCC1849 on the common cold in susceptible populations.

Abstract
Exercise stress testing has been widely undertaken for the diagnosis of heart diseases. The accurate assessment of clinical conditions can be conducted by comparing the findings obtained from the results of stress echocardiography with the changes in the blood/heart rate and electrocardiograms. Numerous overseas studies have reported the utility of stress echocardiography in diagnosing myocardial ischemia; in Japan, the use of this modality for this purpose was included in the national health insurance reimbursable list in 2012. Nevertheless, stress echocardiography is far from being a widespread practice in Japan. This might be due to insufficient equipment (e.g., ergometers, space for test implementation) at each medical institution, shortage of technicians and sonographers who are well experienced and who are responsible for obtaining images during stress testing. The other possible reasons include the limited evidence available in Japan and the lack of a standardized testing protocol. Further dissemination of the practice of exercise stress echocardiography in this country is deemed necessary to establish satisfactory evidence for the use of stress echocardiography in the Japanese population. To this end, efforts are underway to develop a standardized protocol and report format to be adopted throughout Japan. We here present a guideline created by the Guideline Development Committee of the Japanese Society of Echocardiography that describes safe and effective stress echocardiography protocols and report formats. The readers are encouraged to perform exercise stress echocardiography using the proposed template for consensus document and report attached to this guideline.

Abstract
Background Balloon pulmonary angioplasty (BPA) is a treatment option for patients with chronic thromboembolic pulmonary hypertension (CTEPH). Methods and results In 60 patients with CTEPH, we examined the hemodynamic data before and after BPA. In addition, the sequential ECG findings for right ventricular hypertrophy (RVH) were assessed. The mean pulmonary arterial pressure (mPAP) decreased from 38 ± 11 to 20 ± 4 mm Hg (p < 0.05). The ROC analysis showed that the S waves in V5, R waves in V1 + S waves in V5, S waves in I, and QRS axis were significant predictors of an mPAP ≧ 30 mm Hg (AUC > 0.75, p < 0.01). The predictive values for the mPAP before the BPA were the S and R waves in lead V6, and P waves in lead II (33.417 + 0.078 × P in II − 0.10 × R in V6 + 0.012 × S in V6). The change in the mPAP (ΔmPAP) correlated with the change in the amplitudes of the ECGs: ΔS wave in lead I (R = 0.544, p < 0.001), ΔR in V1 + S in V5 (R = 0.476, p < 0.001), and ΔP wave in II (R = 0.511, p < 0.001). At 6 months of follow-up, the improvement in an R in V1 + S in V5 of ≧10 mm implied a better functional status. Conclusion BPA therapy reduced the pulmonary arterial pressure in patients with CTEPH and was associated with an improvement in the ECG findings related to RVH.

Abstract
Objectives To evaluate whether repeated brain natriuretic peptide (BNP) measurements after percutaneous transluminal septal myocardial ablation (PTSMA) provide prognostic information regarding the response to PTSMA in patients with drug-refractory hypertrophic obstructive cardiomyopathy (HOCM). Background Plasma BNP levels are associated with clinical outcomes in patients with HOCM. However, the prognostic value of plasma BNP level changes before and after PTSMA remains unclear. Methods We measured the plasma BNP levels serially before and after PTSMA, and evaluated the relationship between the changes in plasma BNP levels and clinical improvement in 47 patients. The patients were assigned to two groups based on the reduction in the New York Heart Association class ≥1 (good responder) or <1 (poor responder) before and after PTSMA. The Kansas City Cardiomyopathy Questionnaire (KCCQ) was used to measure health status. Results The plasma BNP levels gradually decreased after PTSMA, although the levels plateaued 3 months until 12 months after PTSMA. Although the plasma BNP levels and resting left ventricular outflow tract peak pressure gradient before PTSMA were comparable between the groups, the ratio of the BNP levels before and after PTSMA in the good responder group was significantly lower than that in the poor responder group (0.43 (range, 0.24–0.68) vs 0.78 (range, 0.62–0.93), p=0.002). The KCCQ score changes in the good responder group were significantly higher than those in the poor responder group. Conclusions The plasma BNP level ratio was associated with long-term clinical improvement of heart failure after PTSMA for drug-refractory HOCM.

Abstract
Background Right ventricular (RV) function is an independent predictor of clinical outcomes in patients with pulmonary arterial hypertension (PAH). However, it remains controversial which RV parameter should be measured as an appropriate index for the treatment of PAH. The aim of this study was to identify the most useful parameter that correlates with hemodynamics and predicts clinical outcomes in PAH. Results Most of the clinical and echocardiographic RV parameters were significantly correlated with pulmonary vascular resistance (PVR) as well as mean pulmonary arterial pressure (mPAP). Among these, three dimensional right ventricular ejection fraction (3DRVEF) showed the strongest hemodynamic correlation, followed by 6-minute walk distance. Receiver operating characteristic analysis of association with cardiac events including death, hospitalization, and intervention revealed a greater area under the curve for 3DRVEF than for mPAP (0.78 vs. 0.74). Kaplan-Meier analysis showed that patients with 3DRVEF less than 38% had significantly shorter event-free survival than those with greater than 38% (P = 0.0007). Finally, the Cox proportional hazards analysis revealed that 3DRVEF, but not mPAP, was an independent predictor of clinical events in PAH. Materials and Methods Eighty-six consecutive patients were enrolled in this study. RV hemodynamic parameters were measured by right heart catheterization (RHC). RV function was assessed using two-dimensional speckle-tracking echocardiography and three-dimensional transthoracic echocardiography (3DTTE) to evaluate RV free wall global strain (RVFS) and RVEF. Conclusions RVEF measured by 3DTTE could be a useful parameter for noninvasively assessing RV hemodynamics and predicting the clinical outcomes in PAH patients.

Abstract
Echocardiography plays a pivotal role as an imaging modality in the modern cardiology practice. Information derived from echocardiography is definitely helpful for a patient care. The Japanese Society of Echocardiography has promoted echocardiography for a routine clinical and research use. One of the missions of the Society is to provide information that is useful for high-quality examinations. To ensure it, we believe equipment in good conditions and a comfortable environment are important for both a patient and an examiner. Thus, the Committee for Guideline Writing, the Japanese Society of Echocardiography published brief guidance for the routine use of echocardiography equipment in 2015. Recently, the importance of international standardization has been emphasized in the medical laboratories. Accordingly, the committee has revised and updated our guidance for the routine use of echocardiography equipment.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) has a poor prognosis because of the associated progressive right heart failure. Accurate evaluation of right ventricular (RV) function would thus be useful to predict prognosis. However, the significance of RV diastolic function remains unclear. We aimed to identify which echocardiographic measures are most accurate, and potentially useful, in assessing RV diastolic function in patients with CTEPH, and to study the effects of balloon pulmonary angioplasty (BPA) on them. We enrolled 53 CTEPH patients who underwent BPA. Echocardiographic parameters, including two-dimensional speckle-tracking echocardiography, were compared to the hemodynamic parameters measured by right heart catheterization before and after BPA. RV strain rate during early diastole (SR_E), tricuspid e' and right atrial area (RAA) were ameliorated after BPA, concomitant with a decrease in the time constant of the RV pressure curve during diastole (tau), indicating the improvement of RV diastolic function. Among them, SR_E had the strongest correlation with tau (r = - 0.39, p < 0.001). Furthermore, the receiver operating characteristic analyses revealed that E/SR_E (AUC 0.704) and inferior vena cava diameter (AUC 0.726) had a stronger association with higher mean right atrial pressure than RAA (AUC 0.632). In contrast, RAA had a stronger correlation with 6 min-walk distances than SR_E (r = - 0.39, p < 0.001 vs. r = 0.30, p = 0.005). Taken together, echocardiographic assessment of RV diastolic function might be associated with hemodynamics as well as exercise tolerance in patients with CTEPH, indicating its benefits in evaluating the therapeutic effects of BPA.

Abstract
Riociguat is a soluble guanylate cyclase stimulator used for pulmonary hypertension (PH) treatment. We evaluated right ventricular (RV) contractile function in 27 PH patients receiving riociguat. A comparison of pre- and post-administration echocardiographic studies demonstrated significantly improved RV strain after riociguat treatment, even after adjusting for RV afterload.
