Abstract
INTRODUCTION Some previous studies have reported that a first-step ethanol infusion into the vein of Marshall (EIVOM) with touch-up radiofrequency (RF) ablation can facilitate mitral isthmus (MI) block and improves the ablation outcomes in persistent atrial fibrillation (PeAF) patients. However, the effect of an initial RF ablation with an adjunctive EIVOM has not been fully investigated. METHODS This study enrolled 233 PeAF patients undergoing pulmonary vein isolation and linear ablation including an MI, roof line, and cavotricuspid isthmus ablation. An EIVOM was performed when endocardial ablation with or without coronary sinus ablation failed to create MI block. RESULTS Bidirectional MI block was achieved in 224 patients (96.1%). Among them, MI block was obtained by only RF ablation in 174/224 patients (77.7%) (RF group) and an adjunctive EIVOM was needed in 50/224 (22.3%) (EIVOM group). During the follow-up, 113 (64.9%) RF group patients were free from AF/atrial tachycardia compared to 41 (82.0%) EIVOM group patients (log-rank p = .045). In a multivariate Cox regression analysis, an adjunctive EIVOM was associated with a lower recurrence rate (hazard ratio = 0.39, 95% confidence interval = 0.17-0.78, p = .006). CONCLUSION An initial RF ablation with an adjunctive EIVOM strategy improved MI ablation's acute success rate and was associated with better clinical outcomes.

Abstract
PURPOSE/OBJECTIVE(S) Salvage radiotherapy (SRT) to the prostate bed is the only curative treatment for patients with biochemical recurrence (BCR) after radical prostatectomy (RP). Although several systematic reviews indicated that a dose escalation in the range of 60-70 Gy improved biochemical control, the effects of radiation doses on clinical relapse after SRT remain unclear. Our aim was to investigate the relationship between radiation doses and clinical relapse-free survival (cRFS) after SRT. MATERIALS/METHODS We identified 295 eligible patients receiving SRT for biochemically recurrent prostate cancer after RP between 2005 and 2018 at 15 institutions. Sixteen patients (5%) received short-term (< 6 months) androgen deprivation therapy (ADT) following RP and/or concurrently with SRT. SRT was delivered to the prostate and seminal vesicle bed using photon beams at a median (range) dose of 66 Gy (61-85) in 1.8-3.0 Gy fractions. The primary outcome was cRFS. Clinical relapse was identified on radiological imaging and/or biopsy and included local recurrence, lymph node metastasis, and distant metastasis. In all analyses, doses were recalculated as an equivalent dose in 2-Gy fractions (EQD2) with α/β = 1.5 Gy. Clinical RFS between the EQD2 ≥ 66 Gy (n = 229) and EQD2 < 66 Gy (n = 66) groups were compared using the Log-rank test, followed by univariate and multivariate Cox regression analyses and a subgroup analysis. RESULTS The median follow-up duration was 73 months. Among patients with BCR (n = 119), 79 of 96 (82%) in the EQD2 ≥ 66 Gy group and 21 of 23 (91%) in the EQD2 < 66 Gy group received second salvage ADT (p = 0.36). Among all patients (n = 295), clinical relapse was identified in 22 (7%) patients after SRT. Six-year biochemical relapse-free survival (bRFS), cRFS, cancer-specific survival (CSS), and overall survival (OS) rates were 58%, 93%, 98%, and 94%, respectively. Six-year cRFS rates were 94% (95% confidence interval [CI], 90-97) in the EQD2 ≥ 66 Gy group and 87% (95% CI, 75-93) in the EQD2 < 66 Gy group (p = 0.020). The multivariate analysis revealed that EQD2 < 66 Gy, Gleason score ≥ 8, seminal vesicle involvement, and PSA at BCR ≥ 0.5 ng/ml correlated with clinical relapse (p = 0.0016, 0.014, 0.011, and 0.027, respectively). The subgroup analysis showed the consistent benefit of EQD2 ≥ 66 Gy in patients across most subgroups including PSA at BCR after RP, extracapsular extension, and age at SRT. CONCLUSION This large multi-institutional observational study demonstrated that a higher SRT dose (EQD2 ≥ 66 Gy) resulted in superior cRFS. The present result supports the dose recommendations in the 2023 National Comprehensive Cancer Network guidelines (64-72 Gy) even in terms of clinical relapse. Prospective trial is warranted to investigate an upper threshold for optimal SRT dose.

Abstract
Post-contrast acute kidney injury (PC-AKI) is a common complication after percutaneous coronary intervention (PCI). However, it is unclear whether or not the effects of PC-AKI on long-term clinical outcomes were different between emergent and elective procedures. Among patients enrolled in the CREDO-Kyoto PCI/CABG (Coronary Revascularization Demonstrating Outcome Study in Kyoto Percutaneous Coronary Intervention/Coronary Artery Bypass Grafting) registry cohort 3, we identified 10,822 patients treated using PCI (emergent PCI stratum: n = 5,022 [46%] and elective PCI stratum: n = 5,860 [54%]). PC-AKI was defined as ≥0.3 mg/100 ml absolute or 1.5-fold relative increase of serum creatinine within 72 hours after PCI. The incidence of PC-AKI was significantly higher after emergent PCI than after elective PCI (10.5% vs 3.7%, p <0.001). In the multivariable logistic regression model, emergent PCI was the strongest independent risk factor for PC-AKI in the entire study population. The excess adjusted risk of patients with PC-AKI relative to those without remained significant for all-cause death in both the emergent and elective PCI strata (hazard ratio 1.87, 95% confidence interval 1.59 to 2.21, p <0.001 and hazard ratio 1.31, 95% confidence interval 1.03 to 1.68, p = 0.03, respectively). There was a significant interaction between the PCI setting (emergent and elective) and the effect of PC-AKI on all-cause death, with a greater magnitude of effect in the emergent PCI stratum than in the elective PCI stratum (p for interaction = 0.01). In conclusion, the incidence of PC-AKI was 2.8 times higher after emergent PCI than after elective PCI. The excess mortality risk of PC-AKI relative to no PC-AKI was greater after emergent PCI than after elective PCI.

Abstract
The Juno Waves instrument measured plasma waves associated with Ganymede's magnetosphere during its flyby on 7 June, day 158, 2021. Three distinct regions were identified including a wake, and nightside and dayside regions in the magnetosphere distinguished by their electron densities and associated variability. The magnetosphere includes electron cyclotron harmonic emissions including a band at the upper hybrid frequency, as well as whistler-mode chorus and hiss. These waves likely interact with energetic electrons in Ganymede's magnetosphere by pitch angle scattering and/or accelerating the electrons. The wake is accentuated by low-frequency turbulence and electrostatic solitary waves. Radio emissions observed before and after the flyby likely have their source in Ganymede's magnetosphere.

Abstract
BACKGROUND A growing body of evidence suggests that non-viral hepatocellular carcinoma (HCC) might benefit less from immunotherapy. MATERIALS AND METHODS We carried out a retrospective analysis of prospectively collected data from consecutive patients with non-viral advanced HCC, treated with atezolizumab plus bevacizumab, lenvatinib, or sorafenib, in 36 centers in 4 countries (Italy, Japan, Republic of Korea, and UK). The primary endpoint was overall survival (OS) with atezolizumab plus bevacizumab versus lenvatinib. Secondary endpoints were progression-free survival (PFS) with atezolizumab plus bevacizumab versus lenvatinib, and OS and PFS with atezolizumab plus bevacizumab versus sorafenib. For the primary and secondary endpoints, we carried out the analysis on the whole population first, and then we divided the cohort into two groups: non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH) population and non-NAFLD/NASH population. RESULTS One hundred and ninety patients received atezolizumab plus bevacizumab, 569 patients received lenvatinib, and 210 patients received sorafenib. In the whole population, multivariate analysis showed that treatment with lenvatinib was associated with a longer OS [hazard ratio (HR) 0.65; 95% confidence interval (CI) 0.44-0.95; P = 0.0268] and PFS (HR 0.67; 95% CI 0.51-0.86; P = 0.002) compared to atezolizumab plus bevacizumab. In the NAFLD/NASH population, multivariate analysis confirmed that lenvatinib treatment was associated with a longer OS (HR 0.46; 95% CI 0.26-0.84; P = 0.0110) and PFS (HR 0.55; 95% CI 0.38-0.82; P = 0.031) compared to atezolizumab plus bevacizumab. In the subgroup of non-NAFLD/NASH patients, no difference in OS or PFS was observed between patients treated with lenvatinib and those treated with atezolizumab plus bevacizumab. All these results were confirmed following propensity score matching analysis. By comparing patients receiving atezolizumab plus bevacizumab versus sorafenib, no statistically significant difference in survival was observed. CONCLUSIONS The present analysis conducted on a large number of advanced non-viral HCC patients showed for the first time that treatment with lenvatinib is associated with a significant survival benefit compared to atezolizumab plus bevacizumab, in particular in patients with NAFLD/NASH-related HCC.

Abstract
BACKGROUND Transcatheter mitral valve repair with the MitraClip system has been established in selected high-risk patients. The MitraClip procedure results in a relatively large iatrogenic atrial septal defect (iASD). This study aimed to investigate the prevalence and clinical course of iASD requiring transcatheter closure following the MitraClip procedure.Methods and Results: This study was conducted at all 59 institutions that perform transcatheter mitral valve repair with the MitraClip system in Japan. The data of patients on whom transcatheter iASD closure was performed were collected. Of the 2,722 patients who underwent the MitraClip procedure, 30 (1%) required transcatheter iASD closure. The maximum iASD size was 9±4 mm (range, 3-18 mm). The common clinical course of transcatheter iASD closure was hypoxemia with right-to-left shunt or right-sided heart failure with left-to-right shunt. Of the 30 patients, 22 (73%) required transcatheter closure within 24 h following the MitraClip procedure, including 12 with hypoxemia and 5 with right-sided heart failure complicated with cardiogenic shock. Of the 5 patients, 2 required mechanical circulatory support devices. Twenty-one patients immediately underwent transcatheter iASD closure, and hemodynamic deteriorations were resolved; however, 1 patient died without having undergone transcatheter closure. CONCLUSIONS Transcatheter iASD closure was required in 1% of patients who underwent the MitraClip procedure. Many of these patients immediately underwent transcatheter iASD closure because of hypoxemia with right-to-left shunt or right-sided heart failure with left-to-right shunt.

Abstract
A 68-year old man underwent bare metal stent (BMS; Palmaz-Shatz stent) implantation in the distal right coronary artery (RCA; #4PL) and balloon angioplasity (BA) in the proximal left circumflex coronary artery (LCX; #11) for stable angina. After 5 years after initial stent implantation, de novo lesion located in mid RCA was treated by BMS (NIR stent) implantation additionally. After 16 years from first BMS implantation, the patient died from heart failure due to cardiac amyloidosis, and pathologic examination was performed for the specimen of stented RCA segment and LCX BA segment. An autopsy demonstrated that the lesions of stented site at RCA and BA site LCX were histopathologically different. In the stented segment, severe luminal stenosis is observed due to marked proliferation of the neointima in all stented sites. In addition, neovascularization and spotty calcification with mild lymphocyte infiltration were observed especially around the struts. In contrast, at the BA site of the proximal LCX lesion, in the neointima, the smooth muscle cells were rather atrophic and abundant collagen fibers were evident in the intercellular spaces, which showed very stable findings. Compared with these BMS implanted portions, the site of BA was associated with a trend for smaller late lumen loss. These findings suggested that in the stented site, chronic inflammatory reaction to the stent struts could evoke continuous proliferation of neointima resulting in severe late lumen loss. <Learning objective: Compared with BMS implantation, BA showed stable lesion with abundant collagen fiber proliferation. It could be possible that remaining inflammatory reactions to the metal of the stent caused the development of late lumen loss in BMS.>.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) treatment remains a big challenge in the field of oncology. The liver disease (viral or not viral) underlying HCC turned out to be crucial in determining the biologic behavior of the tumor, including its response to treatment. The aim of this analysis was to investigate the role of the etiology of the underlying liver disease in survival outcomes. PATIENTS AND METHODS We conducted a multicenter retrospective study on a large cohort of patients treated with lenvatinib as first-line therapy for advanced HCC from both Eastern and Western institutions. Univariate and multivariate analyses were performed. RESULTS Among the 1232 lenvatinib-treated HCC patients, 453 (36.8%) were hepatitis C virus positive, 268 hepatitis B virus positive (21.8%), 236 nonalcoholic steatohepatitis (NASH) correlate (19.2%) and 275 had other etiologies (22.3%). The median progression-free survival (mPFS) was 6.2 months [95% confidence interval (CI) 5.9-6.7 months] and the median overall survival (mOS) was 15.8 months (95% CI 14.9-17.2 months). In the univariate analysis for OS NASH-HCC was associated with longer mOS [22.2 versus 15.1 months; hazard ratio (HR) 0.69; 95% CI 0.56-0.85; P = 0.0006]. In the univariate analysis for PFS NASH-HCC was associated with longer mPFS (7.5 versus 6.5 months; HR 0.84; 95% CI 0.71-0.99; P = 0.0436). The multivariate analysis confirmed NASH-HCC (HR 0.64; 95% CI 0.48-0.86; P = 0.0028) as an independent prognostic factor for OS, along with albumin-bilirubin (ALBI) grade, extrahepatic spread, neutrophil-to-lymphocyte ratio, portal vein thrombosis, Eastern Cooperative Oncology Group (ECOG) performance status and alpha-fetoprotein. An interaction test was performed between sorafenib and lenvatinib cohorts and the results highlighted the positive predictive role of NASH in favor of the lenvatinib arm (P = 0.0047). CONCLUSION NASH has been identified as an independent prognostic factor in a large cohort of patients with advanced HCC treated with lenvatinib, thereby suggesting the role of the etiology in the selection of patients for tyrosine kinase treatment. If validated, this result could provide new insights useful to improve the management of these patients.

Abstract
OBJECTIVE Therapeutic strategies for atrial septal defect (ASD) with severe pulmonary arterial hypertension (PAH) are controversial. This study aimed to evaluate the efficacy of PAH-specific medications and subsequent transcatheter closure (ie, treat-and-repair strategy) on clinical outcomes. METHODS We enrolled 42 patients who were referred to 13 institutions for consideration of ASD closure with concomitant PAH and underwent the treat-and-repair strategy. The endpoint was cardiovascular death or hospitalisation due to heart failure or exacerbated PAH. RESULTS At baseline prior to PAH-specific medications, pulmonary to systemic blood flow ratio (Qp:Qs), pulmonary vascular resistance (PVR), and mean pulmonary artery pressure (PAP) were 1.9±0.8, 6.9±3.2 Wood units and 45±15 mm Hg. Qp:Qs was increased to 2.4±1.2, and PVR and mean PAP were decreased to 4.0±1.5 Wood units and 35±9 mm Hg at the time of transcatheter ASD closure after PAH-specific medications. Transcatheter ASD closure was performed without any complications. During a median follow-up period of 33 months (1-126 months) after transcatheter ASD closure, one older patient died and one patient was hospitalised due to heart failure, but the other patients survived with an improvement in WHO functional class. PAP was further decreased after transcatheter ASD closure. CONCLUSIONS The treat-and-repair strategy results in low complication and mortality rates with a reduction in PAP in selected patients with ASD complicated with PAH who have a favourable response of medical therapy.

Abstract
Abstract
Background
In recent years, the number of elderly congestive heart failure (CHF) cases has been increasing in Japan with the aging of the population. This tendency is particularly remarkable in rural areas where our facilities are located. After admission with CHF, the hospitalization period (PE) was prolonged due to various complications unique to the elderly, and re-exacerbation of CHF occurred shortly after discharge. Approximately 30% of them were readmitted within one year. From August 2015, for shortening of PE and reduction of CHF readmission through the efficiency of CHF treatment and comprehensive patient education, we had introduced a unique clinical pathway (PATH) that provided the immediate use of Tolvaptan and comprehensive education by multi-disciplinary staff after admission.
Purpose
In this study, we verified whether the improvement of clinical prognosis were achieved by introduction of PATH.
Methods
Between April 2014 and July 2019, 635 CHF cases (764 admissions) ware enrolled. We divided them to two groups, N-group before introducing PATH (198 cases, 262 admissions) and P-group applied PATH (437 cases, 502 admission). Between both groups, we compared the various acute care situation, PE and readmission rate with CHF within 1 year after discharge.
Results
There were no differences between P and N-group in mean age, distribution of underlying illness or daily activity level before admission. There ware not also differences about left ventricle function by echocardiography and various blood test data at admission. The enforcement rate of continuous infusion and the rate of urinary catheter placement were significantly lower in the P-group (71 vs 88%; p<0.0001, 52 vs 63%; p<0.01, respectively). And their enforcement duration was significantly shorter in P-group (4.6±5.3 vs 10.5±9.6 days; p<0.0001, 6.3±7.9 vs 12.8±13.1 days; p<0.0001 respectively). The enforcement rate of cardiac rehabilitation was significantly higher in group P (94 vs 84%; p<0.0001), and the starting time of rehabilitation was significantly earlier (2.9±1.5 vs 6.3±4.8th illness day; p<0.0001). As a result, the average HP was significantly shorter in group P (16.5±13.4 vs 28.6±24.1 days, p<0.0001). The readmission rate with CHF within one year after discharge was significantly lower in group P (23 vs 36%; p<0.001).
Conclusion
By the introduction of our original clinical pathway for congestive heart failure, the efficiency of medical care was achieved and the mean hospitalization period was widely shortened. In addition, by the through comprehensive patient education by multi-disciplinary staff involved in the pathway, the self-restraint life style after discharge seemed to be maintained and the readmission with worsening of heart failure was significantly suppressed.

Abstract
Abstract
Background
The relative apical sparing pattern (RASP) of left ventricular longitudinal strain (LS) is determined on the strain polar map, while global longitudinal strain (GLS) is measured using speckle-tracking echocardiography and is frequently associated with cardiac amyloidosis (CA). According to recent reports, some elderly patients with aortic stenosis (AS) suffer from transthyretin CA and have a poor prognosis. Accordingly, we aimed to investigate the association of RASP and outcome of patients with severe AS.
Methods
We retrospectively studied 157 consecutive patients (age: 81±10 years, 33% men) with severe AS (mean transaortic pressure gradient: 49 mmHg) and preserved ejection fraction (>50%). After measuring GLS, RASP was semi-quantitatively and quantitatively assessed. Semi-quantitative RASP (sRASP) was defined as reduction of LS (more than −10%), showing light red or blue in ≥5 segments out of the basal six segments, relative to apical LS (less than −15%) showing red. This analysis was independently performed in a blinded manner by two observers. Quantitative RASP (qRASP) was calculated using the following formula: average apical LS/(average basal LS + average mid-ventricle LS), then qRASP ≥1 was determined as positive according to the previous paper. Patients were followed up to determine their outcomes, i.e., sudden cardiac death or unexpected admission due to heart failure over a median duration of 1.9 years. Concordance of sRASP was assessed using the kappa statistic, and a Cox proportional hazards model was used to assess the association between the parameters and primary outcome.
Results
The consistency in the observations of the two sonographers in identifying sRASP was found to be excellent (κ = 1.00). sRASP and qRASP were observed in 24 (15%) and 42 (27%) patients, respectively, and were significantly associated with the primary outcome (n=44; 28%). The representative case is shown in figure (left panel). Further, positive sRASP was associated with the outcome after adjusting for the Euro score, NYHA ≥II, and GLS (hazard ratio = 2.69, p=0.01). The model based on these covariates significantly improved following the addition of sRASP (Figure; right panel). In addition, sRASP was observed in four patients out of 50 patients who underwent aortic valve replacement. Of these, one patient had the primary outcome (25%). On the other hand, in the remaining 46 patients without sRASP, four patients had the outcome (9%).

Conclusions
RASP was observed in some patients with severe AS and has been shown to have increasing importance in predicting adverse cardiac events in such patients.

Abstract
We compare electron and UV observations mapping to the same location in Jupiter's northern polar region, poleward of the main aurora, during Juno perijove 5. Simultaneous peaks in UV brightness and electron energy flux are identified when observations map to the same location at the same time. The downward energy flux during these simultaneous observations was not sufficient to generate the observed UV brightness; the upward energy flux was. We propose that the primary acceleration region is below Juno's altitude, from which the more intense upward electrons originate. For the complete interval, the UV brightness peaked at ~240 kilorayleigh (kR); the downward and upward energy fluxes peaked at 60 and 700 mW/m2, respectively. Increased downward energy fluxes are associated with increased contributions from tens of keV electrons. These observations provide evidence that bidirectional electron beams with broad energy distributions can produce tens to hundreds of kilorayleigh polar UV emissions.

Abstract
BACKGROUND Copeptin, a surrogate marker of pro-arginine vasopressin, is expected to be a marker in cardiovascular diseases. Its utility for predicting long-term clinical outcomes in heart failure (HF), however, has not been adequately evaluated in daily clinical practice in Japan. METHODS To assess the relationship of serum copeptin at admission with long-term clinical outcomes, we evaluated serum copeptin at admission in consecutive 107 patients hospitalized for HF between April 2011 and July 2012. The primary outcome measure was defined as a composite of all-cause death and re-admission for HF (all-cause death/HF). RESULTS In this study population, median serum copeptin at admission was 15.5 (6.7-32.0)pmol/L. As compared with the low-copeptin group (<18pmol/L, N=60), the high-copeptin group (≥18pmol/L, N=47) included more male patients and those with prior myocardial infarction, prior HF, low left ventricular ejection fraction, and chronic kidney disease. During median 4.5 (1.0-5.5) years of clinical follow-up, the cumulative incidence of all-cause death/HF was significantly higher in the high-copeptin than in the low-copeptin group (63.4% versus 33.0% at 1 year, and 85.2% versus 77.2% at 5 years, log-rank p=0.03). After adjusting for confounders, high-copeptin was still an independent predictor for all-cause death/HF [hazard ratio (95% confidence interval): 1.77 (1.04-3.01), p=0.03]. CONCLUSION Copeptin was suggested as a useful marker for predicting long-term clinical outcomes in patients with HF.

Abstract
BACKGROUND Biomarkers for detection of transient myocardial ischemia in patients with unstable angina (UA) or for very early diagnosis of acute myocardial infarction (AMI) are not currently available. METHODS AND RESULTS We performed two sequential screenings of autoantibodies elevated shortly after the onset of acute coronary syndrome (ACS), and focused on metalloendopeptidase nardilysin (NRDC) among 19 identified candidate antigens. In a retrospective analysis among 93 ACS and 117 non-ACS patients, the serum level of NRDC was significantly increased in patients with ACS compared with that in patients with non-ACS (2073.5±189.8pg/ml versus 775.7±63.4pg/ml, P<0.0001). The area under the curve of NRDC for the diagnosis of ACS was 0.822 by the receiver operating characteristic curves analysis. In the time course analysis in 43 consecutive ACS patients (AMI: N=35 and UA: N=8), serum concentration of NRDC was significantly increased even in UA patients with a peak serum NRDC levels reached at admission both in AMI and UA patients. In a mouse model of AMI, we found an acute increase in serum NRDC and reduced NRDC expression in ischemic regions shortly after coronary artery ligation. NRDC expression was also reduced in infarcted regions in human autopsy samples from AMI patients. Moreover, the short treatment of primary culture of rat cardiomyocytes with H2O2 or A23187 induced NRDC secretion without cell toxicity. CONCLUSION NRDC is a promising biomarker for the early detection of ACS, even in UA patients without elevation of necrosis markers.

Abstract
With the development of transplantation of hepatocytes into the spleen, interest has focused on the metabolic changes associated with hepatocyte proliferation. As these changes are important for drug metabolism in hepatocytes, we examined the expression and inducibility of the cytochrome P450 IIIA family within transplanted hepatocytes. Fetal hepatocytes were harvested at 20 days of gestation from spontaneously hypertensive rats (SHRs) and transplanted into recipient adult SHR spleens. Microscopic examination of the recipient spleens 4 and 10 wk after transplantation revealed masses of hepatocytes with cordlike structures in the red pulp. Proliferating hepatocytes were detected with a bromodeoxyuridine (BrdU) immunohistochemical stain. Immunochemical studies detected cytochromes (cytos) P450 p and P450 HLp in fetal hepatocytes before transplantation without prior induction. And although these cytos were not detected by 10 wk after transplantation, they were induced with dexamethasone. These results demonstrated that fetal hepatocytes can be transplanted successfully into recipient spleens and suggested that fetal hepatocytes grow in the spleen, similar to the adult hepatocyte response.

Abstract
Patients with open bite often show a weak occlusal force and temporomandibular disorders (TMDs). If these are the main cause of open bite, it may be hypothesized that both pre-pubertal and adult open-bite patients would show a weak occlusal force and abnormal condylar motion. The purpose of this study was to test this hypothesis. Test group subjects consisted of 13 consecutive pre-pubertal and 13 adult patients with anterior open bite. They were compared with age-matched normal subjects. The adult open-bite group showed a weaker occlusal force and a shorter range of condylar motion compared with the control subjects. In the pre-pubertal subjects, however, there were no significant differences in the occlusal force and range of condylar motion between the open-bite and control groups. Therefore, these results suggest that a weak occlusal force or TMDs may not be the main cause of open bite.

Abstract
A 68-year-old female underwent bare-metal stent (BMS) implantation in the right coronary artery (RCA) for ST-segment elevation myocardial infarction. Recurrent refractory restenosis with peri-stent contrast staining (PSS) formation was observed in the stented lesion at follow-up angiography at 7, 11, and 14 months after the index stent implantation. After 2 repeated interventions, this patient was referred to coronary artery bypass grafting due to occlusion of RCA and progression of proximal left anterior descending coronary artery lesion at 15 months after stent implantation. Pathologic examination of the surgically resected specimen of stented RCA segment revealed total occlusion with dense fibrous collagenous tissue and significant inflammatory cell infiltration including scattered eosinophils. Extensive loss of medial smooth muscle layer was observed in the vessel wall, which was likely to be the cause of PSS. In the course of treatment, this patient was found to have chromium allergy with positive patch test. Allergic reactions to chromium released from the stent might be one of the triggering mechanisms for in-stent restenosis and PSS after BMS implantation. <Learning objective: Peri-stent contrast staining (PSS) was an abnormal angiographic finding suggesting presence of contrast material outside the stent border after sirolimus-eluting stent implantation. However, PSS is rarely seen with bare-metal stents (BMSs), and PSS and refractory restenosis after BMS implantation suggests the relation with metal allergy. We must think of metal allergy after the development of refractory restenosis and PSS with BMS implantation.>.

Abstract
An 82-year-old woman with severe aortic stenosis was referred. She had previously undergone mitral valve replacement. We planned transcatheter aortic valve implantation (TAVI) with transfemoral approach. We planned to use the Safari-dedicated TAVI guidewire. No studies have reported clinical application of the dedicated TAVI guidewire in a patient with the previous mitral valve replacement. Thus, we conducted a simulation using a three-dimensional heart model to confirm the safety of the procedure. The procedure was successful without any complications. This case is the first to show that the dedicated TAVI guidewire can be safely used in patients with preexisting mitral valve.

Abstract
BACKGROUND AND PURPOSE Reversible cerebral vasoconstriction syndrome is characterized by thunderclap headache and diffuse segmental vasoconstriction that resolves spontaneously within 3 months. Previous reports have proposed that vasoconstriction first involves small distal arteries and then progresses toward major vessels at the time of thunderclap headache remission. The purpose of this study was to confirm centripetal propagation of vasoconstriction on MRA at the time of thunderclap headache remission compared with MRA at the time of reversible cerebral vasoconstriction syndrome onset. MATERIALS AND METHODS Of the 39 patients diagnosed with reversible cerebral vasoconstriction syndrome at our hospital during the study period, participants comprised the 16 patients who underwent MR imaging, including MRA, within 72 hours of reversible cerebral vasoconstriction syndrome onset (initial MRA) and within 48 hours of thunderclap headache remission. RESULTS In 14 of the 16 patients (87.5%), centripetal propagation of vasoconstriction occurred from the initial MRA to remission of thunderclap headache, with typical segmental vasoconstriction of major vessels. These mainly involved the M1 portion of the MCA (10 cases), P1 portion of the posterior cerebral artery (10 cases), and A1 portion of the anterior cerebral artery (5 cases). CONCLUSIONS This study found evidence of centripetal propagation of vasoconstriction on MRA obtained at the time of thunderclap headache remission, compared with MRA obtained at the time of reversible cerebral vasoconstriction syndrome onset. If clinicians remain unsure of the diagnosis during early-stage reversible cerebral vasoconstriction syndrome, this time point represents the best opportunity to diagnose reversible cerebral vasoconstriction syndrome with confidence.

Abstract
AIM Severe gastrointestinal bleeding sometimes occurs in patients with aortic stenosis (AS), known as Heyde's syndrome. This syndrome is thought to be caused by acquired von Willebrand syndrome and is characterized by reduced large von Willebrand factor (vWF) multimers. However, the relationship between the severity of AS and loss of large vWF multimers is unclear. METHODS We examined 31 consecutive patients with severe AS. Quantitative evaluation for loss of large vWF multimers was performed using the conventional large vWF ratio and novel large vWF multimer index. This novel index was defined as the ratio of large multimers of patients to those of controls. RESULTS Loss of large vWF multimers, defined as the large vWF multimer index <80%, was detected in 21 patients (67.7%). The large vWF multimer ratio and the large vWF multimer index were inversely correlated with the peak aortic gradient (R = -0.58, p=0.0007, and R=-0.64, p<0.0001, respectively). Anemia defined as hemoglobin <9.0 g/dl was observed in 12 patients (38.7%), who were regarded as Heyde's syndrome. Aortic valve replacement was performed in 7 of these patients, resulting in the improvement of anemia in all patients from a hemoglobin concentration of 7.5±1.0 g/dl preoperatively to 12.4±1.3 g/dl postoperatively (p<0.0001). CONCLUSIONS Acquired von Willebrand syndrome may be a differential diagnosis in patients with AS with anemia. The prevalence of AS-associated acquired von Willebrand syndrome is higher than anticipated.

Abstract
Percutaneous coronary intervention (PCI) for anomalous coronary arteries is often difficult because the support provided by the guide catheter is insufficient. We encountered a patient with severe three-vessel coronary disease including a totally occluded anomalous right coronary artery (RCA) originating from the left sinus of Valsalva. Initial PCI for the anomalous RCA via the transradial approach failed. Therefore, we constructed a three-dimensional (3D) aortocoronary model and conducted an in vitro simulation to plan the second PCI and found that a Judkins left (JL) 3.5 guide catheter in the power position yielded maximum backup support for the anomalous RCA. Thus, the second PCI was conducted using an 8 Fr JL 3.5 guide catheter in the power position via the transfemoral approach. The procedure was smooth and successful, without any adverse events. Our experience suggests that case-specific 3D models are useful for strategic planning of complex PCIs.

Abstract
In Japan, transcatheter aortic valve implantation (TAVI) with Edwards-SAPIEN XT valve (Edwards Lifesciences Inc., Irvine, CA, USA) started in October 2013. All institutions should undergo a training period to perform TAVI independently. Balloon aortic valvuloplasty (BAV) as a bridge to TAVI during the training period should be performed with caution to avoid severe aortic regurgitation (AR) because bailout TAVI is not possible. We present a case in which BAV was successfully performed as a bridge to TAVI during the training period. The patient was an 85-year-old man with medically uncontrollable congestive heart failure due to severe aortic valve stenosis. The aortic valve area was 0.60 cm2 with a left ventricular ejection fraction of 20%. TAVI was considered a safe but high-risk strategy owing to the unstable hemodynamic condition. We chose BAV as a bridge therapy to TAVI. The aortic annulus diameter was 25.3 mm on computed tomography scans. We chose a 20-mm balloon catheter to avoid BAV-induced AR. Transfemoral TAVI was performed successfully 16 days after BAV using a 26-mm SAPIEN XT valve. The postoperative course was uneventful. The case demonstrated BAV as a bridge therapy to TAVI can be safely and effectively performed during the training period. <Learning objective: All institutions should undergo a training period to start transcatheter aortic valve implantation (TAVI). Balloon aortic valvuloplasty (BAV) during the training period should be performed with caution. The present case suggests that BAV as a bridge therapy to TAVI can be safely performed during the training period. An accurate measurement of aortic annulus diameter and the use of an undersized balloon catheter might reduce the risk of BAV-related aortic regurgitation.>.

Abstract
BACKGROUND AND PURPOSE In major SAH, the only method to diagnose a preceding minor leak is to ascertain the presence of a warning headache by interview; however, poor clinical condition and recall bias can cause inaccuracy. We devised a neuroradiologic method to diagnose previous minor leak in patients with SAH and attempted to determine whether warning (sentinel) headaches were associated with minor leaks before major SAH. MATERIALS AND METHODS We retrospectively evaluated 127 patients who were admitted with SAH within 48 hours of ictus. Previous minor leak before major SAH was defined as T1WI-detected clearly bright hyperintense subarachnoid blood accompanied by SAH blood on FLAIR images that was distributed over a larger area than bright hyperintense subarachnoid blood on T1WI (T1-FLAIR mismatch). RESULTS The incidence of warning headache before SAH was 11.0% (14 of 127 patients, determined by interview). The incidence of T1-FLAIR mismatch (neuroradiologic diagnosis of minor leak before major SAH) was 33.9% (43 of 127 patients). Of the 14 patients with warning headache, 13 had a minor leak diagnosed by T1-FLAIR mismatch at the time of admission. Variables identified by multivariate analysis as significantly associated with minor leak diagnosed by T1-FLAIR mismatch included 80 years of age or older, rebleeding after admission, intracerebral hemorrhage on CT, and mRS scores of 3-6. CONCLUSIONS We conclude that warning headaches diagnosed by interview are not a product of recall bias but are the result of actual leaks from aneurysms.

Abstract
An 80-year-old male underwent a transcatheter aortic valve implantation (TAVI) for severe senile aortic stenosis. Six weeks after the surgery, he was readmitted to our institution because of a high-grade fever. Transesophageal echocardiography revealed thickening of all three leaflets of the aortic prosthesis and mobile mass on the leaflet, and Streptococcus sanguis was identified from his blood culture. Therefore, he was diagnosed with prosthetic valve endocarditis (PVE) and received intensive intravenous antibiotic therapy. Because he did not respond to the pharmacological therapy, surgical aortic valve replacement (AVR) was indicated although it was considered a relatively high-risk procedure. Herein, we report on the successful surgical AVR in this patient using a pericardial valve after removal of the infected prosthetic valve, and discuss some issues related to this rare complication after TAVI. <Learning objective: Transcatheter aortic valve implantation (TAVI) is a highly effective procedure for patients with symptomatic severe aortic stenosis who are at high risk or deemed inoperable. Because it only requires limited surgical invasiveness, the risk of prosthetic valve endocarditis (PVE) after TAVI is thought to be low. However, PVE can occur even early after TAVI. We present our recent such case and discuss some issues related to this rare complication.>.

Abstract
The quasiskutterudite superconductor Sr_{3}Rh_{4}Sn_{13} features a pronounced anomaly in electrical resistivity at T^{*}∼138 K. We show that the anomaly is caused by a second-order structural transition, which can be tuned to 0 K by applying physical pressure and chemical pressure via the substitution of Ca for Sr. A broad superconducting dome is centered around the structural quantum critical point. Detailed analysis of the tuning parameter dependence of T^{*} as well as insights from lattice dynamics calculations strongly support the existence of a structural quantum critical point at ambient pressure when the fraction of Ca is 0.9 (i.e., x_{c}=0.9). This establishes the (Ca_{x}Sr_{1-x})_{3}Rh_{4}Sn_{13} series as an important system for exploring the physics of structural quantum criticality without the need of applying high pressures.

Abstract
BACKGROUND Multifunction cardiogram (MCG) is a computer-enhanced, resting electrocardiogram analysis developed to detect hemodynamically relevant coronary artery disease (CAD). Based on data from previous studies suggesting excellent diagnostic accuracy in detecting CAD, MCG (approved by the Food and Drugs Administration) received a Current Procedure Terminology (CPT) code in 2010 in United States. However, there is no previous study validating MCG by using fractional flow reserve (FFR) as the reference standard. METHODS Multifunction cardiogram Evaluation in Diagnosis of Functional coronary Ischemia sTudy (MED-FIT) was designed as a single-center, prospective study enrolling 100 stable patients with suspected CAD scheduled for coronary angiography. The primary and secondary analyses evaluated the diagnostic performance of the MCG severity score to detect functional myocardial ischemia by FFR ≤0.80, and angiographically significant coronary stenosis (percent diameter stenosis ≥50%) by quantitative coronary angiography. RESULTS The current analysis set consisted of 91 patients in whom MCG data with adequate quality was obtained. The prevalence of positive functional myocardial ischemia and angiographically significant stenosis in the current study was 42.7% and 41.8%, respectively. Area under the receiver operating characteristics curve (AUC) of the MCG severity score for functional myocardial ischemia and angiographically significant stenosis was low (AUC 0.51, 95% confidence interval [CI] 0.38-0.63, and AUC 0.58, 95%CI 0.46-0.70, respectively). Sensitivity, and specificity of the MCG severity score for functional myocardial ischemia and angiographically significant stenosis was also low (32%/67%, and 37%/72%) using a cutoff value of 4.0. CONCLUSIONS Diagnostic performance of the MCG severity score was poor for both functional myocardial ischemia, and angiographically significant stenosis.

Abstract
BACKGROUND Recent randomized clinical trials have reported favorable clinical outcomes after the use of drug-eluting stents (DES) in patients with acute coronary syndrome (ACS). However, the long-term efficacy and safety outcomes, bleeding outcome in particular, after DES implantation in ACS patients have not been thoroughly evaluated in a real-world population. METHODS AND RESULTS We evaluated long-term clinical outcomes in 565 consecutive ACS patients who underwent DES implantation in an emergency setting between 2004 and 2011 (ST-segment elevation acute myocardial infarction [STEMI]: n=269, non-STEMI/unstable angina pectoris: n=296). Mean clinical follow-up period in this study was 4.6±2.0 years. The cumulative incidence of all-cause death, cardiac death, myocardial infarction, stent thrombosis and target-lesion revascularization was 6.9%, 4.0%, 2.2%, 1.3% and 8.4% at 1 year, and 19.6%, 6.7%, 5.6%, 3.0% and 13.9% at 5 years, respectively. The cumulative 5-year incidence of major bleeding events was 8.4% (n=42). Fatal bleeding events, however, occurred in only 4 patients, even including 2 patients who required resuscitation upon arrival at the hospital. Of the 42 patients with major bleeding events, 39 were taking dual antiplatelet therapy (DAPT) at the time of bleeding. CONCLUSIONS DES implantation provided favorable long-term clinical outcomes with an acceptably low incidence of fatal bleeding in a real-world population of ACS patients. However, prolonged DAPT seems to be associated with major bleeding after DES implantation.
