Background: Although there are reports on the recurrence prevention in the chronic phase using direct oral anticoagulants (DOACs) for deep vein thrombosis (DVT) in patients with cancer, acute thrombus regression effect using DOACs has not been assessed. This study aimed to assess the thrombus regression effect of initial treatment using edoxaban for acute lower-extremity DVT in patients with active cancer.
Methods and results: In this observational study, among the inpatients with cancer and lower-extremity DVT who underwent initial treatment with edoxaban at our hospital from November 2019 to December 2021, 34 consenting patients were recruited in this study. The quantitative ultrasound thrombus (QUT) score of thrombus volume was calculated at baseline (before administration) and 7-14 days after the start of edoxaban administration, using lower-extremity venous ultrasound to evaluate changes in thrombus volume. The primary and secondary endpoints were the acute thrombus regression effect of edoxaban and the impact of patients' clinical frailty on the thrombus regression effect, respectively. Anticoagulant therapy with edoxaban significantly reduced QUT score (p < 0.001). In addition, regardless of the Clinical Frailty Scale scores, QUT score decreased significantly.
Conclusion: Initial treatment with edoxaban was effective for lower-extremity DVT in patients with cancer. In addition, the effect was the same independent of the degree of frailty.

Background: Assessment of the pattern of the RV outflow tract Doppler provides insights into the hemodynamics of chronic thromboembolic pulmonary hypertension (CTEPH). We studied whether pre-operative assessment of timing of the pulmonary flow systolic notch by Doppler echocardiography is associated with long-term survival after pulmonary endarterectomy (PEA) for CTEPH.
Methods: Fifty-nine out of 61 consecutive CETPH patients (mean age 53 ± 14 years, 34% male) whom underwent PEA between June 2002 and June 2005 were studied. Clinical, echocardiographic and hemodynamic variables were assessed pre-operatively and repeat echocardiography was performed 3 months after PEA. Notch ratio (NR) was assessed with pulsed Doppler and calculated as the time from onset of pulmonary flow until notch divided by the time from notch until end of pulmonary flow. Long-term follow-up was obtained between May 2021 and February 2022.
Results: Pre-operative mean pulmonary artery pressure (mPAP) was 45 ± 15 mmHg and pulmonary vascular resistance (PVR) was 646 ± 454 dynes.s.cm-5. Echocardiography before PEA showed that 7 patients had no notch, 33 had a NR < 1.0 and 19 had a NR > 1.0. Three months after PEA, echocardiography revealed a significant decrease in sPAP in long-term survivors with a NR < 1.0 and a NR > 1.0, while a significant increase in TAPSE/sPAP was only observed in the NR < 1.0 group. Mean long-term clinical follow-up was 14 ± 6 years. NR was significantly different between survivors and non-survivors (0.73 ± 0.25 vs. 1.1 ± 0.44, p < 0.001) but no significant differences were observed in mPAP or PVR. Long-term survival at 14 years was significantly better in patients with a NR < 1.0 compared to patients with a NR > 1.0 (83% vs. 37%, p = < 0.001).
Conclusion: Pre-operative assessment of NR is a predictor of long-term survival in CTEPH patients undergoing PEA, with low mortality risk in patients with NR < 1.0. Long-term survivors with a NR < 1.0 and NR > 1.0 had a significant decrease in sPAP after PEA. However, the TAPSE/sPAP only significantly increased in the NR < 1.0 group. In the NR < 1.0 group, the 6-min walk test increased significantly between pre-operative and at 1-year post-operative follow-up. NR is a simple echocardiographic parameter that can be used in clinical decision-making for PEA.

The aim of this study was to identify anatomical and clinical factors associated with limb-based patency (LBP) loss, major adverse limb events (MALEs), and poor amputation-free survival (AFS) after an infrapopliteal arterial bypass (IAB) surgery according to the Global Limb Anatomic Staging System. A retrospective analysis of patients undergoing IAB surgery between January 2010 and December 2021 at a single institution was performed. Two-year AFS, freedom from LBP loss, and freedom from MALEs were assessed using the Kaplan-Meier method. Anatomical and clinical predictors were assessed using multivariate analysis. The total number of risk factors was used to calculate risk scores for subsequent categorization into low-, moderate-, and high-risk groups. IABs were performed on 103 patients. The rates of two-year freedom from LBP loss, freedom from MALEs, and AFS were 71.3%, 76.1%, and 77.0%, respectively. The multivariate analysis showed that poor run-off beyond the ankle and a bypass vein caliber of < 3 mm were significantly associated with LBP loss and MALEs. Moreover, end-stage renal disease, non-ambulatory status, and a body mass index of < 18.5 were significantly associated with poor AFS. The rates of freedom from LBP loss and MALEs and the AFS rate were significantly lower in the high-risk group than in the other two groups (12-month low-risk rates: 92.2%, 94.8%, and 94.4%, respectively; 12-month moderate-risk rates: 58.6%, 84.6%, and 78.3%, respectively; 12-month high-risk rates: 11.1%, 17.6%, and 56.2%, respectively; p < 0.001, p < 0.001, and p < 0.001, respectively). IAB is associated with poor clinical outcomes in terms of LBP, MALEs, and AFS in high-risk patients. Risk stratification based on these predictors is useful for long-term prognosis.

Although serum troponin level is the gold standard under the universal definition of acute myocardial infarction (AMI), serum creatinine kinase (CK) and creatine kinase-myocardial band (CK-MB) is still measured in clinical practice as the compliment of troponin level. The purpose of this retrospective study is to illustrate the dramatic change of CK-MB/CK ratio by comparing CK-MB/CK ratio in patients with ST-segment elevation myocardial infarction (STEMI) among ≤ 24 h before reaching peak CK, peak CK, ≤ 24 h after reaching peak CK, and 24-48 h after reaching peak CK. We included 502 patients with STEMI. We calculated each average CK-MB/CK ratio at ≤ 24 h before reaching peak CK, peak CK, ≤ 24 h after reaching peak CK, and 24-48 h after reaching peak CK. The average values were compared using Friedman test. The average CK-MB/CK ratio at ≤ 24 h before reaching peak CK, peak CK, ≤ 24 h after reaching peak CK, and 24-48 h after reaching peak CK was 0.096 (9.6% of CK), 0.098 (9.8% of peak CK), 0.076 (7.6% of CK), and 0.028 (2.8% of CK), respectively. The Friedman test suggested that the CK-MB/CK ratio significantly declined after reaching peak CK (p < 0.001). In conclusion, the CK-MB/CK ratio was around 0.1 (10% of CK) until CK-MB and CK reached the peak, but dropped sharply after reaching peak CK. The CK-MB/CK ratio less than 0.1 (10% of CK) cannot be used to rule out the possibility of AMI, when the onset of symptom is unclear or late presentation.
尽管根据急性心肌梗死(AMI)的通用定义,血清肌钙蛋白水平是金标准,但在临床实践中,血清肌酸激酶(CK)和肌酸激酶-心肌带(CK-MB)仍被作为肌钙蛋白水平的补充指标进行测量。这项回顾性研究的目的是通过比较 ST 段抬高型心肌梗死(STEMI)患者在肌酸激酶达到峰值前≤24 小时、肌酸激酶达到峰值、肌酸激酶达到峰值后≤24 小时和肌酸激酶达到峰值后 24-48 小时的肌酸激酶/肌酸激酶比值,说明肌酸激酶/肌酸激酶比值的巨大变化。我们纳入了 502 名 STEMI 患者。我们计算了达到 CK 峰值前 ≤ 24 小时、达到 CK 峰值、达到 CK 峰值后 ≤ 24 小时和达到 CK 峰值后 24-48 小时的平均 CK-MB/CK 比值。平均值的比较采用 Friedman 检验。达到峰值前≤24小时、达到峰值后≤24小时和达到峰值后24-48小时的平均CK-MB/CK比值分别为0.096(占CK的9.6%)、0.098(占峰值的9.8%)、0.076(占CK的7.6%)和0.028(占CK的2.8%)。Friedman 检验表明,在达到 CK 峰值后,CK-MB/CK 比值明显下降(p

The effect of drug-coated balloons (DCB) on hemodialysis (HD) in patients with femoropopliteal (FP) disease remains uncertain. This study aimed to investigate the outcomes of DCB therapy in patients with FP artery disease on HD. A total of 185 patients with FP lesions (140 HD patients) who underwent DCB treatment were included in the study. The incidence of restenosis and target lesion revascularization (TLR) at 12 months were measured. Risk factors for TLR were also investigated. The mean age was 71.7 years, and diabetes was observed in 82.3% of patients. The mean duration of receiving dialysis was 8.8 years. The mean lesion length was 11.0 cm, and approximately half of the lesions were severely calcified. Severe dissection after DCB therapy was observed in 19.5% of patients. During the follow-up period, 74 restenosis, 68 TLRs, 8 major amputations, and 28 deaths were observed. The freedom rates from restenosis and TLR at 12 months were 63.8% and 71.3%, respectively. The freedom rates after low- and high-dose DCB at 12 months were 61.9% and 70.6% for restenosis (P = 0.49) and 66.4% and 79.4% for TLR (P = 0.095), respectively. Independent risk factors for TLR at 12 months of age were diabetes, chronic limb-threatening ischemia, and severe calcification. When patients were divided into four groups according to the number of these three risk factors, the rates of freedom from TLR at 12 months were 100%, 94.8%, 76.7%, and 30.3% in the groups with no risk factors, any one risk factor, any two risk factors, and all risk factors, respectively (P < 0.0001). Clinical outcomes after endovascular therapy in HD patients with FP disease remain unsatisfactory, even if they are treated with DCB. In particular, patients on HD with diabetes, chronic limb-threatening ischemia, and severe calcification have poor outcomes.

Background: Ablation techniques have evolved greatly with advances in high-density 3D mapping systems over the last few years. Some patients develop atypical atrial flutter (AAFL) after pulmonary vein isolation (PVI). The data regarding follow-up after AAFL ablation as well as predictors of arrhythmia recurrence are lacking. This analysis aims to report procedure success rates and establish predictors of long-term success.
Methods and results: This retrospective cohort study included 45 patients (median age: 69 years; 40% female) who qualified for their first AAFL after PVI. The procedures were performed with the use of conventional ablation-index-guided ThermoCool Smarttouch SF and QDOT MICRO catheters. Freedom from arrhythmia recurrence was used as a primary end point. After 52 weeks of follow-up, 60% of patients suffered from arrhythmia recurrence, but over 70% of the studied cohort reported symptom improvement. In multivariate analysis, class I antiarrhythmics prescription (HR = 0.24 [95% CI 0.06-0.94], p = 0.04) was associated with the lack of arrhythmia recurrence during the follow-up, while cardioversion during procedure was associated with increased risk of arrhythmia recurrence (HR = 7.05 [95% CI 2.09-23.72], p = 0.002).
Conclusions: Long-term success of AAFL ablation procedures is not satisfactory despite improvement in symptoms. Class I antiarrhythmics prescription at the discharge contributes to higher chances of sinus rhythm maintenance, whereas cardioversion during the procedure is related to increased risk of arrhythmia recurrence.

This study aimed to determine the normal reference values and distribution of global longitudinal strain (GLS) in the right and left ventricles of healthy Japanese fetuses during pregnancy. This multi-institutional cohort study included healthy Japanese fetuses during normal pregnancies without maternal or fetal complications between 18 and 40 weeks of gestation. Two-dimensional fetal echocardiographic images of the four-chamber view with a high frame rate were acquired and stored as DICOM clips. Data were collected and analyzed in a central laboratory to measure the left ventricular (LV) and right ventricular (RV) GLS using two-dimensional speckle tracking. In total, 513 fetuses were enrolled. The mean LV-GLS and RV-GLS were - 24.3% ± 3.5% and - 23.5% ± 3.7%, respectively. The magnitude of the GLS, with normal limits in both ventricles, decreased with advancing gestation. LV values were r = 0.34 (95% confidence interval, 0.27-0.42) and p < 0.0001; RV values were r = 0.33 (95% confidence interval, 0.25-0.41) and p < 0.0001. The normal values of healthy Japanese fetuses in healthy pregnancies is the first to be established by the large-scale, multi-institutional cohort study as LV-GLS of 24.3% ± 3.5% and RV-GLS of - 23.5% ± 3.7%, respectively. This can serve as a basic reference for assessing the cardiac functions in Japanese fetuses with various heart diseases.

In 2021, Japan approved transcatheter aortic valve replacement (TAVR) for end-stage renal disease patients on hemodialysis (ESRD-HD). Yet, clinical/anatomical differences and outcomes between patients with and without ESRD-HD remain underexplored. This single-center study enrolled consecutive patients who underwent TAVR with the SAPIEN 3 between 2021 and 2023. Baseline characteristics and outcomes up to 1 year were compared. Inverse probability treatment weighting (IPTW) approach and Cox regression were used. Among 287 eligible patients, 59 had ESRD-HD. Patients with ESRD-HD were predominantly male (59.2% vs. 40.7%; p = 0.01), younger (78.0 [73.5-83.5] vs. 84.0 [79.8-88.0]; < 0.001), with lower body mass index (21.4 [19.6-23.3] vs. 22.9 [20.3-25.3]; p = 0.02], higher surgical risk (Society of Thoracic Surgeons Predicted Risk of Mortality ≧8%: 28 [47.5%] vs. 34 [14.9%]; p < 0.001), and more peripheral artery disease (25.4% vs. 4.8%; p < 0.001). Patients with ESRD-HD had a significantly higher prevalence of severely calcified femoral arteries (12.5% vs. 2.6%; p < 0.001). However, there were no differences in the computed-tomographic (CT) anatomical characteristics of the aortic valve complex (AVC), including the aortic valve calcium score (1995 [1372-3374] vs. 2195 [1380-3172]; p = 0.65) or the presence of moderate or severe left ventricular outflow tract calcification (4.3% vs. 5.2%; p > 0.99). Major vascular complications were rare, and technical (98.3% vs. 98.7%; p > 0.99) and device success (75.9% vs. 82.4%; p = 0.26) rates were high in both. At 1 year, there were no significant differences in a composite endpoint of death, stroke, major bleeding, or myocardial infarction (32.4% vs. 33.2%; HR 1.12; 95% CI 0.45-2.80; p = 0.81), nor its components after baseline adjustment.
2021 年,日本批准为接受血液透析的终末期肾病患者(ESRD-HD)实施经导管主动脉瓣置换术(TAVR)。然而,对于ESRD-HD患者与非ESRD-HD患者之间的临床/解剖学差异和预后仍缺乏深入研究。这项单中心研究招募了在 2021 年至 2023 年期间接受 SAPIEN 3 TAVR 的连续患者。研究比较了基线特征和一年内的疗效。研究采用了逆概率治疗加权(IPTW)法和 Cox 回归法。在287名符合条件的患者中,59人患有ESRD-HD。ESRD-HD患者主要为男性(59.2% vs. 40.7%; p = 0.01)、年轻(78.0 [73.5-83.5] vs. 84.0 [79.8-88.0]; 0.99)。主要血管并发症罕见,两者的技术成功率(98.3% vs. 98.7%;p > 0.99)和装置成功率(75.9% vs. 82.4%;p = 0.26)都很高。1年后,死亡、中风、大出血或心肌梗死的复合终点(32.4% vs. 33.2%;HR 1.12;95% CI 0.45-2.80;p = 0.81)及其组成部分经基线调整后无显著差异。

Radiofrequency (RF) catheter ablation is a well-established therapeutic approach for treating arrhythmias, where lesion size and safety are critical for efficacy. This study explored the impact of varying irrigation flow rates on lesion characteristics using the TactiFlex™ SE Ablation Catheter (TF) in an ex vivo porcine heart model, focusing on the size and safety outcomes associated with low versus standard flow rates. Myocardial slabs from porcine hearts were subjected to ablation using two types of irrigated catheters. Lesion formation was compared between low (8 mL/min for TF) and standard irrigation flow rates (13 mL/min for TF) across different power settings (30, 40, and 50 W). Outcome measures included lesion dimensions, incidence of steam pops, and impedance drops. A total of 210 lesions were generated under various settings. At low flow rates, the TF catheter safely formed larger lesions compared to the standard flow rates without a significant increase in steam pops or impedance drops. Lesions at low flow rates were comparable in size to those formed using other catheters under the standard settings. Conversely, the standard flow settings for TF produced smaller lesions but exhibited higher safety profiles, as evidenced by fewer steam pops and impedance drops. Lower irrigation flow rates using a TF catheter can achieve larger lesions without compromising safety, offering an optimization strategy for RF ablation procedures that balances efficacy and safety. These findings may guide clinicians in tailoring ablation strategies according to individual patient needs.
