Methods and Results: This study enrolled 35 patients who underwent TAVI. Thrombogenicity was evaluated using a total thrombus-formation analysis system (T-TAS) to compute the thrombus-formation area under the curve (PL18-AUC10 and AR10-AUC30). Periprocedural thrombogenic parameters including T-TAS were investigated at pre-TAVI, 2 days, 7 days, and 3 months post-TAVI. Hypoattenuated leaflet thickening (HALT) and maximum leaflet thickness (MLT) were evaluated using contrast-enhanced computed tomography 7 days and 3 months post-TAVI. The associations between thrombogenicity and HALT or MLT were assessed. T-TAS parameters consistently decreased at 2 and 7 days post-TAVI, followed by improvement at 3 months. HALT was detected in 20% and 17% of patients at 7 days and 3 months, respectively, post-TAVI. The median MLT value was 1.60 mm at 7 days and 3 months post-TAVI. A significant positive correlation was observed between the decrease in the AR10-AUC30 and MLT at 7 days post-TAVI. Univariate linear regression analysis revealed a decrease in the AR10-AUC30 and an increase in the D-dimer level as a significant predictor of MLT deterioration. Conclusions: The findings suggested that a transient decrease in thrombogenicity following TAVI predicts leaflet thrombosis, implying that monitoring thrombogenicity may be useful for predicting progression of leaflet thrombosis.","PeriodicalId":94305,"journal":{"name":"Circulation reports","volume":"5 12","pages":"450-458"},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10700031/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138815909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Disrupt CAD IV study enrolled patients with severe coronary artery calcification. The primary safety (30-day major adverse coronary events [MACE], 6.3%) and effectiveness (procedural success, 93.8%) endpoints were achieved. The present analysis evaluated the 2-year outcomes of the study. Methods and Results: Disrupt CAD IV (NCT04151628) was a prospective, single-arm, multicenter study designed for regulatory approval of the Shockwave Coronary C2 IVL system in Japan. Angiographic outcomes were analyzed by an independent core laboratory and adverse events were adjudicated by a Clinical Events Committee. Kaplan-Meier analysis was performed for MACE (composite of cardiac death, MI or target-vessel revascularization [TVR]), target lesion failure (TLF: composite of cardiac death, TV-MI, and target lesion revascularization [TLR]), and stent thrombosis (ST). At 2 years, 62 subjects had completed follow-up. MACE occurred in 12.6% (cardiac death 0.0%, MI 6.3%, TVR 7.9%) and TLF occurred in 7.8% of patients, with both rates driven by non-Q-wave MI events (6.3%). TLR was 3.2%; no ST occurred through 2 years. Conclusions: Treatment with IVL in patients with severely calcified coronary lesions was associated with low rates of MACE, TLR, and ST at 2 years, demonstrating continued durable safety and effectiveness of coronary IVL in a Japanese population.","PeriodicalId":94305,"journal":{"name":"Circulation reports","volume":"5 12","pages":"437-441"},"PeriodicalIF":0.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10700032/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138815903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the safety, usefulness, and patient satisfaction in outpatient care using telehealth with real-time electrocardiogram (ECG) monitoring after catheter ablation. Methods and Results: In all, 38 patients who underwent catheter ablation were followed up using telehealth. At the 3- and 6-month follow-up, a self-fitted Duranta ECG monitoring device was sent to the patient's home before the online consultation. Patients attached the devices themselves, and the doctors viewed the patients by video chat and performed real-time ECG monitoring. The frequency of hospital visits and the ECG monitoring duration were compared with conventional in-person follow-up data (n=102). The completion rate for telehealth follow-up was 32 of 38 patients (84%). The number of hospital visits during the 6 months was significantly lower with telehealth follow-up than with conventional follow-up (median [interquartile range] 1 [1-1] vs. 5 [3-5]; P<0.0001). However, the ECG monitoring duration was approximately 4-fold longer for the telehealth follow-up (median [interquartile range] 89 [64-117] vs. 24 [0.1-24] h; P<0.0001). No major adverse events were observed during the telehealth follow-up. Patient surveys showed high satisfaction with telehealth follow-up due to reduced hospital visits.

Methods and Results: Data from 2,242 consecutive patients admitted to the CCU between 2019 and 2021 (age <80 years, 1,390 [62%]; octogenarians, 655 [29%]; nonagenarians, 197 [8.7%]) were reviewed using the in-hospital database for the Tokyo CCU Network. The primary cause of admission was acute coronary syndrome in younger patients and octogenarians (58% and 49%, respectively) and acute heart failure (AHF) in nonagenarians (42%). The proportions of females, underweight, hypertension, atrial fibrillation, myocardial infarction, stroke, previous heart failure, anemia, and malnutrition were higher among octo- and nonagenarians than among younger patients. In-hospital and 1-year mortality rates were greater in octo- and nonagenarians (younger vs. octogenarian vs. nonagenarian, 2.0% vs. 3.8% vs. 5.6% and 4.1% vs. 11.9% vs. 19.0%, respectively). Multivariate analysis revealed that 1-year mortality was associated with octo-/nonagenarian status (odds ratio [OR] 2.24 and 2.64), AHF (OR 2.88), body mass index (OR per 1-kg/m2 0.91), and albumin concentration (OR per 1-g/dL 0.27).

Methods and Results: The World Alliance Society of Echocardiography (WASE) Normal Values Study was conducted to examine normal echocardiographic values in 15 countries. Using the WASE study database, we analyzed 2-dimensional echocardiographic parameters of RV size and systolic function in 192 healthy Japanese individuals and compared them with those obtained from 153 healthy American individuals. In the Japanese population, the absolute values of RV dimensions were smaller for women than men, although the difference disappeared after the data were adjusted for body surface area. RV dimensions, RV length and RV area were smaller in the elderly, but age did not affect RV systolic function. The absolute value, but not the adjusted value, of RV size tended to be smaller in Japanese than American individuals for both sexes. For men, RV systolic function parameters were lower in the Japanese population. This trend was not seen in women. Conclusions: The present study identified normal reference values for RV size and systolic function in a healthy Japanese population. Sex, age, and race had a significant impact on RV size; however, this trend was weak for RV systolic function.","PeriodicalId":94305,"journal":{"name":"Circulation reports","volume":"5 11","pages":"424-429"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10632071/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134650771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
