ABSTRACT
A 9-year-old boy was suspected of having acute myocardial infarction and emergency coronary angiogram was performed. No signs of flow limitation in either coronary artery was detected. We performed intravascular ultrasonography from the ascending aorta, which showed a ridge on the left main trunk acting like a valve, resulting in significant stenosis. Percutaneous coronary intervention with stent deployment was performed with good result.

BACKGROUND: The impact of very low baseline levels of low-density lipoprotein cholesterol (LDL-C) on patients with coronary artery disease remains unclear. METHOD: We enrolled 39,439 patients of the pooled population from the CREDO-Kyoto registries Cohorts 1, 2, and 3. The study population consisted of 33,133 patients who had undergone their first coronary revascularization. We assessed the risk for mortality and cardiovascular events according to quintiles of the baseline LDL-C levels. RESULTS: Patients in the very low LDL-C quintile (<85â¯mg/dL) had more comorbidities than those in the other quintiles. Lower LDL-C levels were strongly associated with anemia, thrombocytopenia, and end-stage renal disease. The cumulative 4-year incidence of all-cause death increased as LDL-C levels decreased (very low: 19.4â¯%, low: 14.5â¯%, intermediate: 11.1â¯%, high: 10.0â¯%, and very high: 9.2â¯%; pâ¯<â¯0.001), which was driven by both the early and late events. After adjusting for baseline characteristics, the adjusted risks of the very low and low LDL-C quintiles relative to the intermediate LDL-C quintile remained significant for all-cause death (very low: HR 1.29, 95â¯% CI 1.16-1.44, pâ¯<â¯0.001; low: HR 1.15, 95â¯% CI 1.03-1.29, pâ¯=â¯0.01). The excess adjusted risks of the lowest LDL-C quintile relative to the intermediate LDL-C quintile were significant for clinical outcomes such as cardiovascular death (HR 1.17, 95â¯% CI 1.01-1.35), non-cardiovascular death (HR 1.35, 95â¯% CI 1.15-1.60), sudden death (HR 1.44, 95â¯% CI 1.01-2.06), and heart failure admission (HR 1.11 95â¯% CI 1.01-1.22), while there was no excess risk for the lowest LDL-C quintile relative to the intermediate LDL-C quintile for myocardial infarction and stroke. CONCLUSIONS: Lower baseline LDL-C levels were associated with more comorbidities and a significantly higher risk of death, regardless of cardiovascular or non-cardiovascular causes, in patients who underwent coronary revascularization.

A 73-year-old Japanese man with a history of distal biliary cancer treated by pancreatoduodenectomy developed pancreatic acinar cell carcinoma (PACC) treated by remnant pancreatectomy and adjuvant chemotherapy. Thirteen months after surgery, multiple liver metastases developed and FOLFOX chemotherapy was initiated. Based on the PACC diagnosis and a positive family history for breast and ovarian cancer genetic testing was performed which revealed a pathogenic germline BRCA2 variant (c.8629G > T, p.Glu2877Ter). Olaparib therapy was initiated and the metastases responded well (partial response). PACC is a BRCA2-associated cancer which may respond well to PARP inhibitors.

The purpose of preoperative biliary drainage (PBD) is to reduce complications during the perioperative period. The extrahepatic bile duct comprises distal and hilar bile ducts and assessing the need for PBD must be considered separately for each duct, as surgical procedures and morbidities vary. The representative disease-causing distal bile duct obstruction is pancreatic cancer. A randomized controlled trial has revealed that PBD carries the risk of recurrent cholangitis and pancreatitis before surgery, thus eliminating the need for PBD when early surgery is feasible. However, neoadjuvant therapy has seen a rise in recent years, resulting in longer preoperative waiting periods and an increased demand for PBD. In such cases, metal stents are preferable to plastic stents due to their lower stent occlusion rates. When endoscopic transpapillary biliary drainage (EBD) is not viable, endoscopic ultrasound-guided biliary drainage may be a suitable substitute. In the hilar bile duct, the representative disease-causing obstruction is hilar cholangiocarcinoma. PBD's necessity has long been a subject of contention. In spite of earlier criticisms of routine PBD, recent views have emerged recommending PBD, particularly when major hepatectomy is required, to prevent postoperative liver failure. Given the risk of tumor seeding associated with percutaneous transhepatic biliary drainage, EBD is preferable. Nevertheless, as its shortcomings involve recurrent cholangitis until surgery due to stent or tube obstruction, it is necessary to seek out novel approaches to circumvent complications. In this review we summarize the current evidence for PBD in patients with distal and hilar biliary obstruction.
ABSTRACT
A 31-year-old man with neurofibromatosis type 1 (NF-1) had undergone resection of a malignant peripheral nerve sheath tumor (MPNST) on the buttock 3 months previously. He subsequently underwent mechanical thrombectomy for a hyperacute left middle cerebral artery embolism. Histopathologically, the emboli comprised neurofilament-positive pleomorphic tumor cells with geographic necrosis and conspicuous mitosis and were identified as MPNST. The patient died of respiratory failure due to lung MPNST metastasis on day 15 of hospitalization. To our knowledge, this is the first report of a spontaneous cerebral embolism due to MPNST in a NF-1 patient.
ABSTRACT
BACKGROUND: Hypertrophic cardiomyopathy (HCM) is often concomitant with sleep-disordered breathing (SDB), which can cause adverse cardiovascular events. Although an appropriate approach to SDB prevents cardiac remodelling, detection of concomitant SDB in patients with HCM remains suboptimal. Thus, we aimed to develop a machine learning-based discriminant model for SDB in HCM. METHODS: In the present multicentre study, we consecutively registered patients with HCM and performed nocturnal oximetry. The outcome was a high Oxygen Desaturation Index (ODI), defined as 3% ODI >10, which significantly correlated with the presence of moderate or severe SDB. We randomly divided the whole participants into a training set (80%) and a test set (20%). With data from the training set, we developed a random forest discriminant model for high ODI based on clinical parameters. We tested the ability of the discriminant model on the test set and compared it with a previous logistic regression model for distinguishing SDB in patients with HCM. RESULTS: Among 369 patients with HCM, 228 (61.8%) had high ODI. In the test set, the area under the receiver operating characteristic curve of the discriminant model was 0.86 (95% CI 0.77 to 0.94). The sensitivity was 0.91 (95% CI 0.79 to 0.98) and specificity was 0.68 (95% CI 0.48 to 0.84). When the test set was divided into low-probability and high-probability groups, the high-probability group had a higher prevalence of high ODI than the low-probability group (82.4% vs 17.4%, OR 20.9 (95% CI 5.3 to 105.8), Fisher's exact test p<0.001). The discriminant model significantly outperformed the previous logistic regression model (DeLong test p=0.03). CONCLUSIONS: Our study serves as the first to develop a machine learning-based discriminant model for the concomitance of SDB in patients with HCM. The discriminant model may facilitate cost-effective screening tests and treatments for SDB in the population with HCM.

Tight junctions (TJs) are important factors constituting the physical barriers of the skin, and their suppression has been described in various conditions, such as aged skin and atopic dermatitis lesions. However, the methods for improving skin TJ function remain insufficient. Therefore, to obtain compounds that can improve TJ function, we developed a novel high-throughput screening system termed live-cell immunostaining to evaluate cell surface-localized claudin-1 (CLDN1) with high selectivity using normal human epidermal keratinocytes (NHEKs). Heparinoid and phospho-pyridoxal (p-Pyr), a metabolite of pyridoxine, were identified as hit compounds. In addition, heparinoid was strongly suggested to increase CLDN1 expression by inhibiting epidermal growth factor receptor signaling. By contrast, p-Pyr did not enhance CLDN1 expression, but it accelerated the translocation of CLDN1 to the cell surface. Finally, we confirmed that heparinoid and p-Pyr improved barrier function in NHEKs in a transepithelial electrical resistance assay. In conclusion, heparinoid and p-Pyr could potentially ameliorate skin conditions by improving TJ function.

BACKGROUND AND AIMS: High bleeding risk (HBR) and acute coronary syndrome (ACS) subtypes are critical in determining bleeding and cardiovascular event risk after percutaneous coronary intervention (PCI). METHODS AND RESULTS: In 4476 ACS patients enrolled in the STOPDAPT-3, where the no-aspirin and dual antiplatelet therapy (DAPT) strategies after PCI were randomly compared, the pre-specified subgroup analyses were conducted based on HBR/non-HBR and ST-segment elevation myocardial infarction (STEMI)/non-ST-segment elevation ACS (NSTE-ACS). The co-primary bleeding endpoint was Bleeding Academic Research Consortium (BARC) type 3 or 5, and the co-primary cardiovascular endpoint was a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, or ischaemic stroke at 1 month. Irrespective of the subgroups, the effect of no-aspirin compared with DAPT was not significant for the bleeding endpoint (HBR [N = 1803]: 7.27 and 7.91%, hazard ratio (HR) 0.91, 95% confidence interval (CI) 0.65-1.28; non-HBR [N = 2673]: 3.40 and 3.65%, HR 0.93, 95% CI 0.62-1.39; Pinteraction = 0.94; STEMI [N = 2553]: 6.58 and 6.56%, HR 1.00, 95% CI 0.74-1.35; NSTE-ACS [N = 1923]: 2.94 and 3.64%, HR 0.80, 95% CI 0.49-1.32; Pinteraction = 0.45), and for the cardiovascular endpoint (HBR: 7.87 and 5.75%, HR 1.39, 95% CI 0.97-1.99; non-HBR: 2.56 and 2.67%, HR 0.96, 95% CI 0.60-1.53; Pinteraction = 0.22; STEMI: 6.07 and 5.46%, HR 1.11, 95% CI 0.81-1.54; NSTE-ACS: 3.03 and 1.71%, HR 1.78, 95% CI 0.97-3.27; Pinteraction = 0.18). CONCLUSION: In patients with ACS undergoing PCI, the no-aspirin strategy compared with the DAPT strategy failed to reduce major bleeding events irrespective of HBR and ACS subtypes. The numerical excess risk of the no-aspirin strategy relative to the DAPT strategy for cardiovascular events was observed in patients with HBR and in patients with NSTE-ACS.

PURPOSE: The purpose of this study was to evaluate the changes in membranous septum (MS) length during the cardiac cycle and by measurement methods using the preoperative computed tomography (CT) images for transcatheter aortic valve replacement (TAVR). METHOD: Among 34 consecutive patients who underwent preoperative contrast-enhanced CT for TAVR, we measured MS lengths by three measurement methods (coronal, stretched, and reformatted coronal view method) at 10% intervals in the cardiac cycle. RESULT: MS lengths differed between the three measurement methods in all cardiac phases. Moderate correlations were observed between the MS lengths measured by the coronal view method and the other two methods. In contrast, strong correlations were observed between the MS lengths measured by the stretched view method and the reformatted coronal view method. The frequencies of the minimum and maximum MS lengths during the cardiac cycle tended to be highest at R-R 90% and R-R 30%, respectively. The median MS lengths at R-R 90% were smaller than those at R-R 30% in all measurement methods. CONCLUSION: The MS length in patients undergoing contrast-enhanced CT for TAVR varies notably depending on the cardiac cycle and measurement methods. When evaluating MS length, it is crucial to consider the measurement method and to perform measurements during diastole in order to evaluate the minimum value during the cardiac cycle.

BACKGROUND: It remains unclear whether clopidogrel is better suited than aspirin as the long-term antiplatelet monotherapy following dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI). OBJECTIVES: This study compared clopidogrel monotherapy following 1 month of DAPT (clopidogrel group) with aspirin monotherapy following 12 months of DAPT (aspirin group) after PCI for 5 years. METHODS: STOPDAPT-2 (Short and Optimal Duration of Dual Antiplatelet Therapy 2) is a multicenter, open-label, adjudicator-blinded, randomized clinical trial conducted in Japan. Patients who underwent PCI with cobalt-chromium everolimus-eluting stents were randomized in a 1-to-1 fashion either to clopidogrel or aspirin groups. The primary endpoint was a composite of cardiovascular outcomes (cardiovascular death, myocardial infarction, stroke, or definite stent thrombosis) or major bleeding (TIMI major or minor bleeding). RESULTS: Among 3,005 study patients (age: 68.6 ± 10.7 years; women: 22.3%; acute coronary syndrome: 38.3%), 2,934 patients (97.6%) completed the 5-year follow-up (adherence to the study drugs at 395 days: 84.7% and 75.9%). The clopidogrel group compared with the aspirin group was noninferior but not superior for the primary endpoint (11.75% and 13.57%, respectively; HR: 0.85; 95% CI: 0.70-1.05; Pnoninferiority < 0.001; Psuperiority = 0.13), whereas it was superior for the cardiovascular outcomes (8.61% and 11.05%, respectively; HR: 0.77; 95% CI: 0.61-0.97; P = 0.03) and not superior for major bleeding (4.44% and 4.92%, respectively; HR: 0.89; 95% CI: 0.64-1.25; P = 0.51). By the 1-year landmark analysis, clopidogrel was numerically, but not significantly, superior to aspirin for cardiovascular events (6.79% and 8.68%, respectively; HR: 0.77; 95% CI: 0.59-1.01; P = 0.06) without difference in major bleeding (3.99% and 3.32%, respectively; HR: 1.23; 95% CI: 0.84-1.81; P = 0.31). CONCLUSIONS: Clopidogrel might be an attractive alternative to aspirin with a borderline ischemic benefit beyond 1 year after PCI.

BACKGROUND: There is a scarcity of data evaluating the effect of peripheral artery disease (PAD) on long-term mortality after percutaneous coronary intervention (PCI) relative to coronary artery bypass grafting (CABG) in patients with severe coronary artery disease in real-world practice. METHODS: Among 14,867 consecutive patients who underwent their first coronary revascularization with PCI or isolated CABG between 2011 and 2013 in the CREDO-Kyoto PCI/CABG registry Cohort-3, the current study population consisted of 3380 patients with three-vessel coronary artery disease or left main coronary artery disease. Long-term clinical outcomes were compared between PCI and CABG stratified by the presence or absence of PAD. Median clinical follow-up was 5.9 (IQR: 5.1-6.8) years. RESULTS: There were 461 patients with PAD (PCI: Nâ¯=â¯307, CABG: Nâ¯=â¯154), and 2919 patients without PAD (PCI: Nâ¯=â¯1823, CABG: Nâ¯=â¯1096). The cumulative 5-year mortality after coronary revascularization was 31.2â¯% in patients with PAD and 16.2â¯% in those without PAD (pâ¯<â¯0.0001). There was a higher risk of PCI relative to CABG for all-cause death in patients with and without PAD (adjusted HR, 1.59; 95%CI, 0.99-2.53; pâ¯=â¯0.054, and HR, 1.25; 95%CI, 1.01-1.56; pâ¯=â¯0.04) without interaction (p interaction pâ¯=â¯0.48); Nevertheless, there was no excess risk of PCI relative to CABG for cardiovascular death regardless of PAD. CONCLUSIONS: The long-term mortality after coronary revascularization was significantly higher in severe CAD patients with PAD than those without PAD. There was a higher mortality risk of PCI relative to CABG in patients with and without PAD without interaction, which was mainly driven by excess non-cardiovascular deaths.

In this case, we successfully repositioned the transcatheter heart valve (THV) by pulling it with a snare inserted via the right brachial artery. Attempting to pull the THV via the femoral approach was not successful, due to the vector of the pulling force not being coaxial. Changing the direction of the force by switching to an approach from the right brachial artery successfully prevented perivalvular leakage. While there are previous case reports of repositioning an implanted transcatheter valve in a native valve using a gooseneck snare, to our knowledge, this is the first case of successfully repositioning an implanted transcatheter valve in a valve-in-valve procedure using the precise assessment that can be achieved with intra-procedural transesophageal echocardiography. Learning objective: Perivalvular leakage (PVL) is a major problem after transcatheter aortic valve replacement. In this case, we experienced PVL after implantation of self-expandable transcatheter heart valve (THV) inside the previously inserted Mosaic bioprosthetic valve. Depth of the implanted valve was too low into left ventricle accessed with transesophageal echocardiogram. It is barely known whether THV in surgical implanted aortic valve could be repositioned using snare maneuver, but we successfully pulled the valve via brachial artery and PVL was controlled.
ABSTRACT
Regulatory B cells (Bregs) may play a pivotal role in maintaining human pregnancy. For the first time, to the best of our knowledge, this study noted that cell percentages of CD24hiCD38hi Bregs and CD24hiCD27+ Bregs, which can potentially produce IL-10, are increased in human decidua compared with the mid-luteal phase endometrium. In each case of decidua, the correlation between Bregs and dendritic cell (DC) or natural killer (NK) cell expression was further explored. A positive correlation between the percentage of CD24hiCD38hi Bregs and CD123-CD11c+ myeloid DCs (mDCs) was noted. Furthermore, a significant positive correlation was also observed between the percentage of CD24hiCD27+ Bregs and CD94+CD56brightCD16- suppressive NK cells. These findings regarding decidual Bregs deepen the understanding of the harmonious immunological microenvironment that sustains early human pregnancy.

BACKGROUND: Polypharmacy was reported to be associated with major bleeding in various populations. However, there are no data on polypharmacy and its association with bleeding in patients undergoing percutaneous coronary intervention (PCI).MethodsâandâResults: Among 12,291 patients in the CREDO-Kyoto PCI Registry Cohort-3, we evaluated the number of medications at discharge and compared major bleeding, defined as Bleeding Academic Research Consortium Type 3 or 5 bleeding, across tertiles (T1-3) of the number of medications. The median number of medications was 6, and 88.0% of patients were on ≥5 medications. The cumulative 5-year incidence of major bleeding increased incrementally with increasing number of medications (T1 [≤5 medications] 12.5%, T2 [6-7] 16.5%, and T3 [≥8] 20.4%; log-rank P<0.001). After adjusting for confounders, the risks for major bleeding of T2 (hazard ratio [HR] 1.21; 95% confidence interval [CI] 1.08-1.36; P=0.001) and T3 (HR 1.27; 95% CI 1.12-1.45; P<0.001) relative to T1 remained significant. The adjusted risks of T2 and T3 relative to T1 were not significant for a composite of myocardial infarction or ischemic stroke (HR 0.95 [95% CI 0.83-1.09; P=0.47] and HR 1.06 [95% CI 0.91-1.23; P=0.48], respectively). CONCLUSIONS: In a real-world population of patients undergoing PCI, approximately 90% were on ≥5 medications. Increasing number of medications was associated with a higher adjusted risk for major bleeding, but not ischemic events.
ABSTRACT
Background: There are no studies comparing single-session vs staged multivessel intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in patients with chronic coronary syndrome (CCS) or non-ST-segment-elevation acute coronary syndrome (NSTE-ACS). Objectives: The authors aimed to compare single-session vs staged multivessel IVUS-guided PCI in patients with CCS or NSTE-ACS. Methods: The OPTIVUS-Complex PCI study multivessel cohort was a prospective multicenter single-arm trial enrolling 1,021 patients with CCS or NSTE-ACS undergoing multivessel PCI including left anterior descending coronary artery using IVUS aiming to meet the prespecified OPTIVUS criteria for optimal stent expansion. We compared single-session vs staged multivessel PCI. The primary endpoint was a composite of death, myocardial infarction, stroke, or any coronary revascularization. Results: There were 246 patients (24.1%) undergoing single-session multivessel PCI, and 775 patients (75.9%) undergoing staged multivessel PCI. There was a wide variation in the prevalence of single-session multivessel PCI across the participating centers. The staged multivessel PCI group more often had complex coronary anatomy such as 3-vessel disease, chronic total occlusion, and calcified lesions requiring an atherectomy device compared with the single-session multivessel PCI group. The rates of PCI success, procedural complications, and meeting OPTIVUS criteria were not different between groups. The cumulative 1-year incidence of the primary endpoint was not different between single-session and staged multivessel PCI groups (9.0% vs 10.8%, log-rank P = 0.42). After adjusting confounders, the effect of single-session multivessel PCI relative to staged multivessel PCI was not significant for the primary endpoint (HR: 0.95; 95% CI: 0.58-1.55; P = 0.84). Conclusions: Single-session and staged multivessel IVUS-guided PCI had similar 1-year outcomes.
ABSTRACT
AIMS: The use of tolvaptan is increasing in clinical practice in Japan. However, the characteristics of patients who used tolvaptan and the timing of its use in patients with acute heart failure (AHF) are not fully elucidated. METHODS AND RESULTS: Among consecutive 4056 patients in the Kyoto Congestive Heart Failure registry, we analysed 3802 patients after excluding patients on dialysis, prior or unknown tolvaptan use at admission, and unknown timing of tolvaptan use, and we divided them into two groups: tolvaptan use (N = 773) and no tolvaptan use (N = 3029). The prevalence of tolvaptan use varied widely from 48.7% to 0% across the participating centres. Factors independently associated with tolvaptan use were diabetes, poor medical adherence, oedema, pleural effusion, hyponatraemia, estimated glomerular filtration rate < 30 mL/min/1.73 m2 , moderate/severe tricuspid regurgitation, dobutamine infusion within 24 h, and additional inotropes infusion beyond 24 h after admission. The mortality rate at 90 days after admission was significantly higher in the tolvaptan use group than in the no tolvaptan use group (14.3% vs. 8.6%, P = 0.049). However, after adjustment, the excess mortality risk of tolvaptan use relative to no tolvaptan use was no longer significant (hazard ratio = 1.53, 95% confidence interval = 0.77-3.02, P = 0.22). Patients with tolvaptan use had a longer hospital stay [median (interquartile range): 22 (15-34) days vs. 15 (11-21) days, P < 0.0001] and a higher prevalence of worsening renal failure (47.0% vs. 31.8%, P < 0.0001) and worsening heart failure (24.8% vs. 14.4%, P < 0.0001) than those without. CONCLUSIONS: AHF patients with tolvaptan use had more congestive status with poorer in-hospital outcomes and higher short-term mortality than those without tolvaptan use.

ABSTRACT
It is important to clarify the precise impact of mitral regurgitation (MR) on long-term outcomes in acute myocardial infarction (AMI) patients who underwent percutaneous coronary intervention (PCI). In the Coronary Revascularization Demonstrating Outcome study in Kyoto Acute Myocardial Infarction (CREDO-Kyoto AMI) Registry Wave-2, the study population consisted of 5,266 patients with AMI who underwent PCI. The clinical outcomes of all-cause death, cardiovascular death, and hospitalization for heart failure (HF) were compared according to the severity of MR. Mild and moderate/severe MR were identified in 2,112 (40%) and 531 patients (10%), respectively. Patients with greater severity of MR were more likely to be old, had more co-morbidities, and more often presented with large myocardial infarction with HF. During median follow-up duration of 5.6 (interquartile range: 4.2 to 6.6) years, as the MR severity increased from no, mild, to moderate/severe MR, the cumulative 5-year incidences of all-cause death, cardiovascular death and hospitalization for HF incrementally increased ([15.3%, 19.6%, 33.3%], [8.9%, 11.7%, 21.0%] and [5.9%, 12.4%, 23.9%], respectively, P for all<0.001). After adjusting for confounders, however, mild and moderate/severe MR were not independently associated with the higher risks for all-cause death (hazard ratio [95% confidence interval]:1.05 [0.92 to 1.19], p = 0.51, and 1.10 [0.92 to 1.32], p = 0.28) and cardiovascular death (1.01 [0.85 to 1.21], p = 0.89, and 0.93 [0.73 to 1.18], p = 0.54) as compared with no MR. Both mild and moderate/severe MR were independently associated with the higher risks for hospitalization for HF (1.73 [1.42 to 2.11], p <0.001, and 2.23 [1.73 to 2.87], p <0.001). In a large population of patients with AMI who underwent PCI, MR was not independently associated with higher long-term mortality risk but was independently associated with higher risk for hospitalization for HF.
