Abstract
For pre-procedural planning of left atrial appendage (LAA) closure, sizing is crucial. Although transesophageal echocardiography (TEE) is a standard modality, cardiac computed tomography (CT) is also widely used. The virtual TEE (V-TEE) that our group developed enables us to reconstruct images similar to TEE images from CT images. The software should be helpful to understand and plan the procedure strategy. Accordingly, we investigated the utility of V-TEE. Sixty-six patients at 4 participating sites who completed both CT and TEE prior to LAA closure were included. The LAA diameter at the landing zone (LZ) for WATCHMAN™ device implantation was statistically compared at 0°, 45°, 90°, and 135° between V-TEE and TEE. Among 66 cases, only 3 cases were excluded due to poor imaging quality, and 63 cases were analyzed. The device LZ diameters based on V-TEE were strongly correlated with those based on TEE, despite the significantly greater diameter based on V-TEE with mean differences of 2.4 to 3.0 mm (all of them: P < 0.001). The discordances (V-TEE/TEE ratio) at most angles were significantly larger in the elliptical LAAs. V-TEE provides a valuable method for the evaluation of the LAA diameters. V-TEE-based measurements were larger than conventional TEE-based measurements, especially in cases of elliptical LAAs. The assessment by V-TEE has the potential benefit of ensuring proper device sizing regardless of the LAA morphology.

Abstract
BACKGROUND Percutaneous left atrial appendage closure (LAAC) has increased for those who need alternative to long-term anticoagulation with non-valvular atrial fibrillation (NVAF). METHODS AND RESULTS From September 2019, after initiating WATCHMAN (Boston Scientific, Maple Grove, MN, USA) device implantation, we established Transcatheter Modification of Left Atrial Appendage by Obliteration with Device in Patients from the NVAF (TERMINATOR) registry. Utilizing 729 patients' data until January 2022, we analyzed percutaneous LAAC data regarding this real-world multicenter prospective registry. A total of 729 patients were enrolled. Average age was 74.9 years and 28.5 % were female. Paroxysmal AF was 37.9 % with average CHADS2 3.2, CHA2DS2-VASc 4.7, and HAS-BLED score of 3.4. WATCHMAN implantation was successful in 99.0 %. All-cause deaths were 3.2 %, and 1.2 % cardiovascular or unexplained deaths occurred during follow-up [median 222, interquartile range (IQR: 93-464) days]. Stroke occurred in 2.2 %, and the composite endpoint which included cardiovascular or unexplained death, stroke, and systemic embolism were counted as 3.4 % [median 221, (IQR: 93-464) days]. Major bleeding defined as BARC type 3 or 5 was seen in 3.7 %, and there was 8.6 % of all bleeding events in total [median 219, (IQR: 93-464) days]. CONCLUSIONS These preliminary data demonstrated percutaneous LAAC with WATCHMAN device might have a potential to reduce stroke and bleeding events for patients with NVAF. Further investigation is mandatory to confirm the long-term results of this strategy using this transcatheter local therapy instead of life-long systemic anticoagulation.

Abstract
BACKGROUND Reduced exercise capacity is a prognostic indicator of adverse outcomes in patients with acute myocardial infarction (AMI). However, few studies have evaluated the effectiveness of comprehensive cardiac rehabilitation (CR) in this population. This study aimed to clarify the efficacy of comprehensive CR in patients with AMI and reduced exercise capacity.Methods and Results: This cohort study included 610 patients with AMI who underwent percutaneous coronary intervention. Major adverse cardiovascular events (MACE) were compared between patients who participated in comprehensive outpatient CR for 150 days (CR group; n=430) and those who did not (non-CR group; n=180). During the mean (±SD) follow-up period of 6.1±4.0 years, the CR group exhibited a lower incidence of MACE (log-rank P=0.002). Multivariable analysis revealed that Killip classification, diuretics at discharge, and participation in comprehensive CR were independently associated with MACE. The CR group was further divided into 2 groups, namely reduced exercise capacity (% predicted peak V̇O2<80%; n=241) and preserved exercise capacity (≥80%; n=147), based on the initial cardiopulmonary exercise test. Despite distinct exercise capacities, the incidence of MACE was comparable and physical parameters improved similarly after comprehensive CR in both groups. CONCLUSIONS Comprehensive CR in patients with AMI effectively reduced the incidence of MACE regardless of initial exercise capacity. Cardiologists should actively encourage patients with low exercise capacity to participate in comprehensive CR.

Abstract
BACKGROUND When frailty is considered in patient selection, better outcomes are achieved in transcatheter aortic valve replacement (TAVR) procedures. This study investigated whether patient photographs could be utilized to qualitatively assess patient frailty and independently predict poor outcomes following TAVR. METHODS This study included 1345 patients with severe aortic stenosis who underwent TAVR at the Sakakibara Heart Institute, Japan, between 2013 and 2022. Patient photographs were taken prior to the initial outpatient clinic examination or at discharge in case the patient's first visit was unplanned admission. Frailty was assessed from patient photographs using a four-point photographic frailty scale; 1 (non-frail), 2 (vulnerable), 3 (mild frail), and 4 (frail). Photographic frailty scale of 3 and 4 were defined as high. The primary endpoint was all-cause mortality following TAVR. RESULTS Seven hundred ninety-six patients who had their facial photographs taken within six months before the TAVR procedure were analyzed. Patients with a higher photographic frailty scale belonged to New York Heart Association classes III/IV, and had higher Society of Thoracic Surgeons scores, higher incidence of wheelchair usage, lower hemoglobin, and smaller aortic valve areas. According to the frailty assessment, patients with a higher photographic frailty scale exhibited slower performance in the 5-m walk test, reduced hand grip strength, more severe dementia, had a higher clinical frailty scale, and lower serum albumin level. Multivariable Cox regression analysis revealed that the high photographic frailty scale was independently associated with all-cause mortality (adjusted hazard ratio 1.62, 95 % confidence interval 1.12-2.33, p = 0.010). Kaplan-Meier analysis indicated that patients with high photographic frailty scale had higher all-cause mortality rates compared to those with low scale (log-rank p = 0.011). CONCLUSIONS Patient registration photographs can be used to obtain qualitative assessments of frailty in severe aortic stenosis cases, and such assessments can independently predict poor outcomes following TAVR.

Abstract
Patients with hypertrophic cardiomyopathy (HCM) often have atrial fibrillation, and empiric anticoagulation is recommended in these patients, regardless of other risk factors. However, anticoagulation is not recommended for patients who require hemodialysis (HD) because of the high bleeding risk. We herein report a case of left atrial appendage closure (LAAC) using the Watchman FLX system for a dilated phase HCM patient complicated by persistent atrial fibrillation and requiring HD. LAAC with the Watchman FLX system may be an alternative to antithrombotic medications in patients with dilated HCM complicated by atrial fibrillation and requiring HD.

Abstract
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 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 BARC type 3 or 5, and the co-primary cardiovascular endpoint was a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, or ischemic stroke at 1 month. RESULTS 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%, HR 0.91, 95%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). CONCLUSIONS In patients with ACS undergoing PCI, the no-aspirin strategy compared to 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.

Abstract
The number of patients who underwent transcatheter aortic valve implantation (TAVI) with the potential for reintervention is steadily increasing; however, there is a risk of sinus sequestration (SS) during a redo TAVI. The prevalence, predictors, and risk stratification of the risk for SS remain uncertain. We analyzed computed tomography acquired from 263 patients who underwent TAVI between 2021 and 2022: balloon-expandable valve (BEV) (71%) and self-expandable valve (SEV) (29%). Patients were considered at risk for SS if they met the following: (1) BEV frame > sinotubular junction (STJ) or SEV neocommissure greater than the STJ and (2) valve-to-STJ <2 mm. The risk of left, right, and any SS in 51%, 50%, and 65%, respectively, did not differ between BEV and SEV. The predictors of any SS were the height of the left and right coronary cusp (odds ratio [OR] 0.81 and 0.71, cutoff 18.6 and 19.2 mm, respectively) and STJ minus the annulus diameter (OR 0.65, cutoff 3.7 mm) in BEV, and STJ diameter (OR 0.47, cutoff 27.6 mm) in SEV. The number of predictors stratified the risk of any SS: low risk with BEV at 0 predictors (14% at risk of SS), intermediate risk at 1 predictor (65%), high risk at 2 or 3 predictors (81% and 95%), and low risk with SEV at 0 predictors (33%) versus high risk at 1 predictor (91%). In conclusion, 2/3 of patients who underwent TAVI were at risk of SS. The height of the coronary cusp and the STJ diameter were associated with and adequately stratified the risk of SS.

Abstract
The 23-valent pneumococcal polysaccharide vaccine (PPSV23) has contributed to reducing pneumonia caused by Streptococcus pneumoniae. However, in Japan, invasive pneumococcal diseases caused by non-vaccine-covered serotypes have increased over the years. A 73-year-old man with a history of PPSV23 was referred to our hospital due to persistent fever and back pain following pneumococcal pneumonia. Contrast-enhanced computed tomography revealed an infectious aneurysm (IAA) at the distal part of the aortic arch. The patient was surgically treated with in situ aortic reconstruction and administered antibiotics. On pathogenic examination of the resected IAA, atherosclerotic changed aortic wall, neutrophil infiltration, and abscesses were observed. Although multiple blood culture tests were negative, tissue culture tests and 16S ribosomal RNA gene-based polymerase chain reaction identified S. pneumoniae. According to capsular polysaccharide synthesis B gene-based serotyping, the serotype was identified as 23A, which is not covered with PPSV23. Serotype 23 is among the most frequently identified serotypes in recent years and associated with in-hospital mortality. Although several pneumococcal serotypes are responsible for lethal infections, the association between these serotypes and disease is uncertain. Further studies on the association between pneumococcal serotypes and IAA, and the development of a broader-covered vaccine are required. Learning objective •To be able to make a differential diagnosis of invasive pneumococcal pneumonia in patients with persistent fever and newly emerging back pain following pneumococcal infection.•To understand the importance of combining culture tests and molecular analysis to diagnose invasive pneumococcal diseases accurately.•To understand the threat of non-vaccine-covered serotypes even in patients with vaccination histories because the vaccine is limited to only one-fourth of all pneumococcal serotypes.

Abstract
Low body weight and advanced age are reported to be among the best predictors of osteoporosis, and osteoporosis self-assessment tool (OST) values are calculated using a simple formula to identify postmenopausal women at increased risk of osteoporosis. In our recent study, we demonstrated an association between fractures and poor outcomes in postmenopausal women following transcatheter aortic valve replacement (TAVR). In this study, we aimed to investigate the osteoporotic risk in women with severe aortic stenosis and determined whether an OST could predict all-cause mortality following TAVR. The study population comprised 619 women who underwent TAVR. Compared to a quarter of patients with diagnosis of osteoporosis, 92.4% of participants were at high risk of osteoporosis based on OST criteria. When divided into tertiles based on OST values, patients in tertile 1 (lowest OST) displayed increased frailty, a higher incidence of multiple fractures, and greater Society of Thoracic Surgeons scores. Estimated all-cause mortality survival rates 3 years post-TAVR were 84.2 ± 3.0%, 89.5 ± 2.6%, and 96.9 ± 1.7% for OST tertiles 1, 2, and 3, respectively (p = 0.001). Multivariate analysis showed that the OST tertile 3 was associated with decreased risk of all-cause mortality compared with OST tertile 1 as the referent. Notably, a history of osteoporosis was not associated with all-cause mortality. Patients with high osteoporotic risk are highly prevalent among those with aortic stenosis according to the OST criteria. OST value is a useful marker for predicting all-cause mortality in patients undergoing TAVR.

Abstract
BACKGROUND Left heart abnormalities are risk factors for heart failure. However, echocardiography is not always available. Electrocardiograms (ECGs), which are now available from wearable devices, have the potential to detect these abnormalities. Nevertheless, whether a model can detect left heart abnormalities from single Lead I ECG data remains unclear.Methods and Results: We developed Lead I ECG models to detect low ejection fraction (EF), wall motion abnormality, left ventricular hypertrophy (LVH), left ventricular dilatation, and left atrial dilatation. We used a dataset comprising 229,439 paired sets of ECG and echocardiography data from 8 facilities, and validated the model using external verification with data from 2 facilities. The area under the receiver operating characteristic curves of our model was 0.913 for low EF, 0.832 for wall motion abnormality, 0.797 for LVH, 0.838 for left ventricular dilatation, and 0.802 for left atrial dilatation. In interpretation tests with 12 cardiologists, the accuracy of the model was 78.3% for low EF and 68.3% for LVH. Compared with cardiologists who read the 12-lead ECGs, the model's performance was superior for LVH and similar for low EF. CONCLUSIONS From a multicenter study dataset, we developed models to predict left heart abnormalities using Lead I on the ECG. The Lead I ECG models show superior or equivalent performance to cardiologists using 12-lead ECGs.

Abstract
Background: The number of octo- and nonagenarians admitted to cardiac care units (CCUs) has been increasing in the context of an aging society; however, clinical details and outcomes for these patients are scarce. 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). Conclusions: Approximately 40% of patients admitted to the CCU were octo- or nonagenarians, and being an octo- or nonagenarian, having AHF, a lower body mass index, and lower albumin concentrations were associated with 1-year mortality after CCU admission.

Abstract
Although cardiac rehabilitation (CR) has been shown to improve exercise tolerance and prognosis in patients with cardiovascular diseases, there remains low participation in outpatient CR. This may be attributed to the patients' busy schedules and difficulty in visiting the hospital due to distance, cost, avoidance of exercise, and severity of coronary disease. To overcome these challenges, many countries are exploring the possibility of remote CR. Specifically, there is increasing attention on the development of remote CR devices, which allow transmission of vital information to the hospital via a remote CR application linked to a wearable device for telemonitoring by dedicated hospital staff. In addition, remote CR programs can support return to work after hospitalization. Previous studies have demonstrated the effects of remote CR on exercise tolerance. However, the preventive effects of remote CR on cardiac events and mortality remain controversial. Thus, safe and effective remote CR requires exercise risk stratification for each patient, telenursing by skilled staff, and multidisciplinary interventions. Therefore, quality assurance of telenursing and multi-disciplinary interventions will be essential for remote CR. Remote CR may become an important part of cardiac management in the future. However, issues such as cost-effectiveness and insurance coverage still persist.

Abstract
Background The prognostic impact of optical coherence tomography-diagnosed culprit lesion morphology in acute coronary syndrome (ACS) has not been systematically examined in real-world settings. Methods and Results This investigator-initiated, prospective, multicenter, observational study was conducted at 22 Japanese hospitals to identify the prevalence of underlying ACS causes (plaque rupture [PR], plaque erosion [PE], and calcified nodules [CN]) and their impact on clinical outcomes. Patients with ACS diagnosed within 24 hours of symptom onset undergoing emergency percutaneous coronary intervention were enrolled. Optical coherence tomography-guided percutaneous coronary intervention recipients were assessed for underlying ACS causes and followed up for major adverse cardiac events (cardiovascular death, myocardial infarction, heart failure, or ischemia-driven revascularization) at 1 year. Of 1702 patients with ACS, 702 (40.7%) underwent optical coherence tomography-guided percutaneous coronary intervention for analysis. PR, PE, and CN prevalence was 59.1%, 25.6%, and 4.0%, respectively. One-year major adverse cardiac events occurred most frequently in patients with CN (32.1%), followed by PR (12.4%) and PE (6.2%) (log-rank P<0.0001), primarily driven by increased cardiovascular death (CN, 25.0%; PR, 0.7%; PE, 1.1%; log-rank P<0.0001) and heart failure trend (CN, 7.1%; PR, 6.8%; PE, 2.2%; log-rank P<0.075). On multivariate Cox regression analysis, the underlying ACS cause was associated with 1-year major adverse cardiac events (CN [hazard ratio (HR), 4.49 [95% CI, 1.35-14.89], P=0.014]; PR (HR, 2.18 [95% CI, 1.05-4.53], P=0.036]; PE as reference). Conclusions Despite being the least common, CN was a clinically significant underlying ACS cause, associated with the highest future major adverse cardiac events risk, followed by PR and PE. Future studies should evaluate the possibility of ACS underlying cause-based optical coherence tomography-guided optimization.

Abstract
BACKGROUND The optimal revascularization strategy in patients with multivessel disease and intermediate SYNTAX score (SS) has not been fully elucidated. This study aimed to investigate the clinical outcomes of optimal intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) stratified by SS. METHODS This was a substudy of the OPTIVUS-Complex PCI study Multivessel Cohort, which aimed to meet the prespecified criteria for optimal stent expansion after IVUS-guided PCI. A total of 1,005 patients were divided into 3 groups according to SS: low, ≤22; intermediate, 23 to 32; and high, ≥33. The primary end points were major adverse cardiac and cerebrovascular events (MACCE) defined as a composite of death, myocardial infarction, stroke, or coronary revascularization. RESULTS The cumulative 1-year incidence of the primary end point was significantly higher in patients with high SS than in those with intermediate or low SS (25.0%, 10.9%, and 9.5%, respectively; p = 0.003). This difference was mainly caused by the incidence of coronary revascularization. In the multivariable Cox proportional hazards models, the excess risk of patients with high versus low SS remained significant for the primary end point (hazard ratio 3.19, 95% confidence interval 1.65 to 6.16, p <0.001), whereas the excess risk of patients with intermediate versus low SS was no longer significant (hazard ratio 1.20, 95% confidence interval 0.72 to 2.01, p = 0.46). CONCLUSIONS After IVUS-guided multivessel PCI, patients with intermediate SS had a similar 1-year risk of MACCE to that of patients with low SS, whereas patients with high SS had a higher 1-year risk of MACCE than those with low SS.

Abstract
BACKGROUND The new sizing options of the MitraClip system (Abbott Vascular, Abbott Park, IL, USA) with extended clip arms were recently developed. Its applicability and effectiveness for ventricular functional mitral regurgitation (VFMR) are yet to be investigated. METHODS We retrospectively reviewed consecutive patients with symptomatic VFMR who underwent transcatheter edge-to-edge repair between 2018 and 2022 at the Sakakibara Heart Institute. Pre- and post-procedural mitral valve morphologies were assessed using three-dimensional transesophageal echocardiography. RESULTS In a total of 104 VFMR patients, the posterior mitral leaflet length was 12.8 ± 2.8 mm and 92 % was indicative of the extended arm (≥9 mm). Although baseline VFMR was more severe in the patients treated with the extended arms (n = 35, XT group) than the patients treated with the standard arms (n = 69, NT group), the decrease in VFMR was greater in the XT group (delta three-dimensional vena contracta area - 43 ± 33 mm2 vs. -31 ± 22 mm2, p = 0.030) and residual VFMR was similar between the groups, with a significantly greater reduction in the mitral annulus anterior-posterior diameter (-4.9 ± 2.2 mm vs -3.1 ± 2.1 mm, p < 0.001) and mitral annulus area in the XT group. The use of extended arms was independently associated with shorter procedure time (81 ± 26 min vs 108 ± 41 min) after adjustment for device generation and the number of clips (p = 0.017). CONCLUSIONS Most VFMR patients had enough leaflet lengths for transcatheter edge-to-edge repair using the MitraClip with the extended arms, which was associated with shorter procedure time and a greater decrease in the mitral annular size.

Abstract
Background Information regarding the outcomes of transcatheter aortic valve replacement (TAVR) in men is limited. This study aimed to investigate short- to mid-term outcomes and prognostic predictors in this population. Method and Results The data of 519 men were analyzed from 1,693 consecutive patients with symptomatic severe aortic stenosis who underwent TAVR at six hospitals between April 2010 and July 2020. The primary endpoint was all-cause mortality at 30 days after TAVR. The mean age and Society of Thoracic Surgeons (STS) score were 83.7 ± 5.9 years and 6.3 ± 4.7%, respectively. Overall, 23.5% of patients consumed alcohol with a frequency of > 1 drinks/week, and 12.1% consumed alcohol with a frequency of > 8 drinks/week, while 66.1% were former smokers and 4.2% were current smokers. Mortality at 30 days was 0.8%. During the median follow-up period of 448 days, the estimated survival rates at 1 year post-TAVR was 90.7 ± 1.4%. In multivariate analysis, the serum albumin level [hazard ratio (HR): 2.20, 95% confidence interval (CI):1.36-3.62, p = 0.001], atrial fibrillation (HR: 1.79, 95% CI: 1.13-2.82, p = 0.012), and STS score (HR: 1.33, 95% CI: 1.06-1.67, p = 0.015) were independently associated with all-cause mortality following TAVR. Adjusted hazard ratios of current smoking, heavy drinking, and presence of cancer were 1.05 (95% CI: 0.36-2.98),1.37 (95% CI: 0.75-2.48), and 1.13 (95% CI: 0.75-2.48), respectively. Conclusion Our study demonstrated that serum albumin levels, atrial fibrillation, and STS score were independently associated with all-cause mortality following TAVR in men.

Abstract
Even after successful revascularization with primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI), subsequent adverse events still occur. Previous studies have suggested potential benefits of intravascular imaging, including optical coherence tomography (OCT). However, the feasibility of OCT-guided primary PCI has not been systematically examined in these patients. The ATLAS-OCT (ST-elevation Acute myocardial infarcTion and cLinicAl outcomeS treated by Optical Coherence Tomography-guided percutaneous coronary intervention) trial was designed to investigate the feasibility of OCT guidance during primary PCI for STEMI in experienced centers with expertise on OCT-guided PCI as a prospective, multicenter registry of consecutive patients with STEMI who underwent a primary PCI. The sites' inclusion criteria are as follows: (1) acute care hospitals providing 24/7 emergency care for STEMI, and (2) institutions where OCT-guided PCI is the first choice for primary PCI in STEMI. All patients with STEMI who underwent primary PCI at participating sites will be consecutively enrolled, irrespective of OCT use during PCI. The primary end point will be the rate of successful OCT imaging during the primary PCI. As an ancillary imaging modality to angiography, OCT provides morphologic information during PCI for the assessment of plaque phenotypes, vessel sizing, and PCI optimization. Major adverse cardiac events, defined as a composite of all-cause death, myocardial infarction, and target vessel revascularization at 1 year, will also be recorded. The ATLAS-OCT study will clarify the feasibility of OCT-guided primary PCI for patients with STEMI and further identify a suitable patient group for OCT-guided primary PCI.

Abstract
Background Mitochondrial diseases are a group of genetic disorders caused by nuclear or mitochondrial DNA gene mutations and characterized by multiorgan disorders, including cardiomyopathy. Mitochondrial cardiomyopathy is occasionally complicated by hypertrophic cardiomyopathy with/without left ventricular systolic dysfunction, dilated cardiomyopathy, and left ventricular non-compaction. In such cases, the dilated left ventricle impairs coaptation of the mitral leaflets and leads to functional mitral regurgitation. To date, valvular interventions in patients with mitochondrial cardiopathy have not been investigated. Case summary A 64-year-old woman with mitochondrial cardiopathy was referred to our hospital owing to dyspnoea. She experienced her first admission with heart failure at age 60 years. At 62 years old, she was diagnosed with maternally inherited diabetes and deafness with mitochondrial cardiomyopathy based on mitochondrial DNA sequencing. Despite administration of guideline-directed medical therapy and high-dose taurine supplementation, she was repeatedly hospitalized for heart failure. At admission, transthoracic echocardiography revealed severe functional mitral regurgitation due to left ventricular dilatation. Surgical risk was considered high (Society of Thoracic Surgeons score of 12.6%); therefore, transcatheter edge-to-edge repair with the MitraClip system was performed. Two devices deployed at the middle segment of the anterior and posterior leaflet successfully reduced mitral regurgitation. The patient was free from cardiovascular events during the 2-year follow-up period. Discussion Transcatheter edge-to-edge repair is a less invasive and effective treatment for severe drug-refractory mitral regurgitation in patients with mitochondrial disease. Given the limited therapeutic options for mitochondrial cardiopathy, further studies are required to uncover the mechanism underlying mitochondrial diseases and establish disease-specific treatments.

Abstract
Hyperuricemia is reportedly associated with the progression of carotid intima-media thickness (IMT), a surrogate of cardiovascular risks and events. However, factors associated with carotid IMT progression in patients with asymptomatic hyperuricemia are largely unknown. In this post-hoc analysis of the multicenter, randomized PRIZE study, we analyzed data from a total of 326 patients who underwent carotid ultrasonography in a blind manner at baseline and 24 months to evaluate carotid IMT. Mean and maximum IMT at the common carotid artery (CCA) were measured at a central core laboratory. Factors related to the absolute change in mean and maximum IMT from baseline to 24 months were explored. Overall, the adjusted mean [0.0032 (- 0.0214 to 0.0278) mm] and maximum [0.0011 (- 0.0327 to 0.0351) mm] CCA-IMT increased numerically from baseline to 24 months. Multivariable analysis identified higher body mass index, history of atherosclerotic cardiovascular disease (ASCVD), and lower mean CCA-IMT at baseline as significant factors associated with the increase in mean CCA-IMT. In addition, older age and lower mean CCA-IMT at baseline were significant factors for an increased absolute change in the maximum CCA-IMT at 24 months. The present sub-analysis of the PRIZE study showed higher body mass index, history of ASCVD, and older age as significant factors associated with CCA-IMT progression in patients with asymptomatic hyperuricemia. These factors may be considered when identifying the possible risk of atherosclerotic progression in this specific patient population of hyperuricemia.Trial registration: UMIN000012911 and UMIN000041322.

Abstract
ABSTRACT There were few clinical studies on the relationship between sodium glucose cotransporter 2 inhibitors (SGLT2i) and hematopoiesis in patients with diabetes (DM) and heart failure (HF) with consideration of systemic volume status. A total of 226 DM patients with HF enrolled in the CANDLE trial, a multicenter, prospective, randomized open-label blinded-endpoint trial, were studied. Estimated plasma volume status (ePVS) was calculated based on a weight- and hematocrit-based formula. At baseline, there was no significant difference in hematocrit and hemoglobin between the canagliflozin (n = 109) and glimepiride (n = 116) groups. Hematocrit and hemoglobin at 24 weeks, changes in hematocrit and hemoglobin difference (24 weeks-baseline), and hematocrit and hemoglobin ratio (24 weeks/baseline) were significantly higher in the canagliflozin than in the glimepiride group, respectively. There was no significant difference in ePVS at baseline and 24 weeks between the 2 groups. After adjustment for baseline parameters, canagliflozin correlated positively with changes in hematocrit and hemoglobin difference, and hematocrit and hemoglobin ratio by multivariate linear regression analyses. The difference in hematocrit and hemoglobin between the 2 groups became statistically significant at 3 and 6 months after randomization. There was no heterogeneity between canagliflozin and the characteristics of the patients for hematocrit and hemoglobin difference and ratio. A correlation of the changes in hematocrit and hemoglobin with cardiac and renal improvement was not observed. In conclusion, canagliflozin was associated with an increased hematocrit and hemoglobin in patients with diabetes and HF regardless of their volume status and characteristics.

Abstract
BACKGROUND Echocardiography-based transvalvular mean pressure gradient (ECHO-mPG) used to assess the forward valve function and structural valve deterioration could overestimate the true pressure gradient. This study evaluated the discrepancy between invasive and ECHO-mPG after transcatheter aortic valve implantation (TAVI) with respective valve type and size, its impact on a device success criterion, and predictors of a pressure discrepancy. METHODS We analyzed 645 patients registered in a multicenter TAVI registry (balloon-expandable valve [BEV]: 500; self-expandable valve [SEV]: 145). The invasive transvalvular mPG was measured after valve implantation using two Pigtail catheters (CATH-mPG), while the ECHO-mPG was measured within 48 h after TAVI. Pressure recovery (PR) was calculated using the following formula: ECHO-mPG × effective orifice area (EOA)/ascending aortic area (AoA) × (1 - EOA/AoA). RESULTS ECHO-mPG was weakly correlated with (r = 0.29, p < 0.0001), and consistently overestimated CATH-mPG in both BEV and SEV, and respective valve sizes. The magnitude of the discrepancy was larger for BEV than SEV (p < 0.001) and smaller valves (p < 0.001). After the correction of PR using the above formula, the pressure discrepancy remained for BEV (p < 0.001) but not SEV (p = 0.10). The proportion of patients with an ECHO-mPG > 20 mmHg decreased from 7.0% to 1.6% after correction (p < 0.0001). Among the baseline and procedural variables, post-procedural ejection fraction, BEV versus SEV, and smaller valves were associated with a larger discrepancy in mPG. CONCLUSIONS ECHO-mPG could be overestimated after TAVI, especially in patients with a smaller BEV. A higher ejection fraction, BEV, and smaller valves were predictors of a pressure discrepancy between CATH- and ECHO-mPG.

Abstract
BACKGROUND Clinical outcomes and treatment selection after completing the randomized phase of modern trials, investigating antiplatelet therapy (APT) after percutaneous coronary intervention (PCI), are unknown. OBJECTIVES The authors sought to investigate cumulative 15-month and 12-to-15-month outcomes after PCI during routine care in the MASTER DAPT trial. METHODS The MASTER DAPT trial randomized 4,579 high bleeding risk patients to abbreviated (n = 2,295) or standard (n = 2,284) APT regimens. Coprimary outcomes were net adverse clinical outcomes (NACE) (all-cause death, myocardial infarction, stroke, and BARC 3 or 5 bleeding); major adverse cardiac and cerebral events (MACCE) (all-cause death, myocardial infarction, and stroke); and BARC type 2, 3, or 5 bleeding. RESULTS At 15 months, prior allocation to a standard APT regimen was associated with greater use of intensified APT; NACE and MACCE did not differ between abbreviated vs standard APT (HR: 0.92 [95% CI: 0.76-1.12]; P = 0.399 and HR: 0.94 [95% CI: 0.76-1.17]; P = 0.579; respectively), as during the routine care period (HR: 0.81 [95% CI: 0.50-1.30]; P = 0.387 and HR: 0.74 [95% CI: 0.43-1.26]; P = 0.268; respectively). BARC 2, 3, or 5 was lower with abbreviated APT at 15 months (HR: 0.68 [95% CI: 0.56-0.83]; P = 0.0001) and did not differ during the routine care period. The treatment effects during routine care were consistent with those observed within 12 months after PCI. CONCLUSIONS At 15 months, NACE and MACCE did not differ in the 2 study groups, whereas the risk of major or clinically relevant nonmajor bleeding remained lower with abbreviated compared with standard APT.

Abstract
Aims Coronary microvascular dysfunction (CMD) is related to the pathophysiology, mortality, and morbidity of heart failure with preserved ejection fraction (HFpEF). A novel single-photon emission computed tomography (SPECT) camera with cadmium zinc telluride (CZT) detectors allows for the quantification of absolute myocardial blood flow and myocardial flow reserve (MFR) in patients with coronary artery disease. However, the potential of CZT-SPECT assessing for CMD has never been evaluated in patients with HFpEF. Methods and results The clinical records of 127 consecutive patients who underwent dynamic CZT-SPECT were retrospectively reviewed. Rest and stress scanning were started simultaneously with 3 and 9 MBq/kg of 99mTc-sestamibi administration, respectively. Dynamic CZT-SPECT imaging data were analysed using a net-retention model with commercially available software. Transthoracic echocardiography was performed in all patients. The MFR value was significantly lower in the HFpEF group (mean ± SEM = 2.00 ± 0.097) than that in the non-HFpEF group (mean ± SEM = 2.74 ± 0.14, P = 0.0004). A receiver operating characteristic analysis indicated that if a cut-off value of 2.525 was applied, MFR could efficiently distinguish HFpEF from non-HFpEF. Heart failure with preserved ejection fraction had a consistently low MFR, regardless of the diastolic dysfunction score. Heart failure with preserved ejection fraction patients with MFR values lower than 2.075 had a significantly higher incidence of heart failure exacerbation. Conclusion Myocardial flow reserve assessed by CZT-SPECT was significantly reduced in patients with HFpEF. A lower MFR was associated with a higher hospitalization rate in these patients. Myocardial flow reserve assessed by CZT-SPECT has the potential to predict future adverse events and stratify the severity of disease in patients with HFpEF.

Abstract
Sodium-glucose cotransporter 2 inhibitors (SGLT2is) reduce the risk of heart failure progression and mortality rates. Moreover, osmotic diuresis induced by SGLT2 inhibition may result in an improved heart failure prognosis. Independent of conventional diuretics in patients with type 2 diabetes (T2D) and chronic heart failure, especially in patients with heart failure with preserved ejection fraction (HFpEF), it is unclear whether SGLT2i chronically reduces estimated plasma volume (ePV). As a subanalysis of the CANDLE trial, which assessed the effect of canagliflozin on N-terminal pro-brain natriuretic peptide (NT-proBNP), we examined the change (%) in ePV over 24 weeks of treatment based on the baseline level associated with diuretic usage. In the CANDLE trial, nearly all patients were clinically stable (NYHA class I-II), with approximately 70% of participants presenting a baseline phenotype of HFpEF. A total of 99 (42.5%) patients were taking diuretics (mostly furosemide) at baseline, while 134 (57.5%) were not. Relative to glimepiride, canagliflozin significantly reduced ePV without worsening renal function in patients in both groups: -4.00% vs. 1.46% (p = 0.020) for the diuretic group and -6.14% vs. 1.28% (p < 0.001) for the nondiuretic group. Furthermore, canagliflozin significantly reduced serum uric acid without causing major electrolyte abnormalities in patients in both subgroups. The long-term beneficial effect of SGLT2i on intravascular congestion could be independent of conventional diuretic therapy without worsening renal function in patients with T2D and HF (HFpEF predominantly). In addition, the beneficial effects of canagliflozin are accompanied by improved hyperuricemia without causing major electrolyte abnormalities.

Abstract
INTRODUCTION Spatial characteristics of localized sources of persistent atrial fibrillation (AF) identified by unipolar-based panoramic mapping software (CARTOFINDER) remain unclear. We evaluated spatial characteristics of bi-atrial AF localized sources in relation to complex fractionated atrial electrocardiograms (CFAEs) and atrial low voltage area (LVAs) (≤0.35 mV during AF). METHODS AND RESULTS Twenty consecutive patients with persistent AF underwent bi-atrial voltage, CFAE, and CARTOFINDER mapping before the beginning of ablation (18 [90%] patients, initial procedure; 2 [10%] patients, repeat procedure). CFAEs were recorded using the interval confidence level (ICL) mode and defined as sites with a confidence level of ≥80% of maximal ICL number. We elucidated the following: (1) differences in the rate of AF localized sources and CFAEs inside or outside the atrial LVAs; (2) distribution of AF localized sources and CFAEs; and (3) distance between the closest points of AF localized sources and CFAEs. A total of 270 AF localized sources and 486 CFAEs were identified in 20 patients. AF localized sources were confirmed more often outside atrial LVAs than CFAEs (71% vs. 46% outside LVA, p < .001). AF localized sources and CFAEs were diffusely distributed without any tendency in bi-atria. Mean distance between closest AF localized sources and CFAEs was 22 ± 8 mm. CONCLUSION AF localized sources identified by CARTOFINDER are different therapeutic targets as compared to CFAEs and could be confirmed both inside and outside atrial LVAs.

Abstract
Background Obesity is a major risk factor for cardiovascular disease; however, a paradoxical effect of obesity has been reported in patients with heart failure or myocardial infarction. Although several studies have suggested the same obesity paradox in patients undergoing transcatheter aortic valve replacement (TAVR), they included a limited number of underweight patients. Objectives This study aimed to clarify the effect of being underweight on TAVR outcomes. Methods We retrospectively analyzed 1,693 consecutive patients undergoing TAVR between 2010 and 2020. The patients were categorized according to body mass index: underweight (<18.5 kg/m2; n = 242), normal weight (18.5 to 25 kg/m2; n = 1,055), and overweight (>25 kg/m2; n = 396). We compared midterm outcomes after TAVR among the 3 groups; all clinical events were in accordance with the Valve Academic Research Consortium-2 criteria. Results Underweight patients were more likely to be women and have severe heart failure symptoms, peripheral artery disease, anemia, hypoalbuminemia, and pulmonary dysfunction. They also had lower ejection fractions, smaller aortic valve areas, and higher surgical risk scores. Device failure, life-threatening bleeding, major vascular complications, and 30-day mortality occurred more frequently in underweight patients. The midterm survival rate of the underweight group was inferior to those of the other 2 groups (P < 0.0001; average follow-up, 717 days). In the multivariate analysis, underweight was associated with noncardiovascular mortality (HR: 1.78; 95% CI: 1.16-2.75) but not cardiovascular mortality (HR: 1.28; 95% CI: 0.58-1.88) after TAVR. Conclusions Underweight patients had a worse midterm prognosis, demonstrating the obesity paradox in this TAVR population.

Abstract
OBJECTIVES We review our experience with 13 periprocedural aortic dissection (AD) cases caused by transcatheter aortic valve replacement (TAVR). BACKGROUND AD is a potentially lethal complication of TAVR; however, only sporadic case reports have been published to date. METHODS Among 1335 consecutive patients who underwent TAVR in 2013-2021, we retrospectively extracted 13 patients (1.0%) with TAVR-related AD (Stanford type A in 6 [46%], type B in 7 [54%]). AD was defined as a new-onset dissected layer of the aortic wall and diagnosed by aortography, computed tomography, or transesophageal echocardiography. RESULTS Five of the six type A AD cases (83%) were detected during TAVR versus only one of the seven type B AD cases (14%). Four of the seven type B AD cases (57%) were asymptomatic and incidentally detected on computed tomography. The presumed causes of AD were injury by the delivery sheath (39%), delivery catheter (23%), valve implantation (15%), stent edge (15%), and pre-dilation balloon (8%). Complicated AD occurred in only one patient (8%). Considering the patient's age and prohibitive surgical risk, all patients were treated conservatively and free of any aortic-related deaths or interventions during a follow-up of 1087 days. CONCLUSIONS TAVR-related AD is a rare but life-threatening condition that may be underdiagnosed. Its optimal therapy remains unclear, and conservative management might be an option for selected patients. Further studies are needed to elucidate the incidence, risk factors, effective screening, optimal therapy, and outcomes of TAVR-related AD.

Abstract
BACKGROUND More than half of the world's population lives in Asia. With current life expectancies in Asian countries, the burden of cardiovascular disease is increasing exponentially. Overcrowding in the emergency departments (ED) has become a public health problem. Since 2015, the European Society of Cardiology recommends the use of a 0/1-h algorithm based on high-sensitivity cardiac troponin (hs-cTn) for rapid triage of patients with suspected non-ST elevation acute coronary syndrome (NSTE-ACS). However, these algorithms are currently not recommended by Asian guidelines due to the lack of suitable data. METHODS The DROP-Asian ACS is a prospective, stepped wedge, cluster-randomized trial enrolling 4260 participants presenting with chest pain to the ED of 12 acute care hospitals in five Asian countries (UMIN; 000042461). Consecutive patients presenting with suspected acute coronary syndrome between July 2022 and Apr 2024 were included. Initially, all clusters will apply "usual care" according to local standard operating procedures including hs-cTnT but not the 0/1-h algorithm. The primary outcome is the incidence of major adverse cardiac events (MACE), the composite of all-cause death, myocardial infarction, unstable angina, or unplanned revascularization within 30 days. The difference in MACE (with one-sided 95% CI) was estimated to evaluate non-inferiority. The non-inferiority margin was prespecified at 1.5%. Secondary efficacy outcomes include costs for healthcare resources and duration of stay in ED. CONCLUSIONS This study provides important evidence concerning the safety and efficacy of the 0/1-h algorithm in Asian countries and may help to reduce congestion of the ED as well as medical costs.

Abstract
Background Nonagenarians are a growing age group in patients undergoing transcatheter aortic valve replacement (TAVR); however, the appropriate use of TAVR in this population remains discussed because of their limited life expectancy and worse outcome reported. Objectives The authors aimed to evaluate clinical characteristics and the prognostic impact of nonagenarians. Methods We analyzed consecutive patients undergoing transfemoral TAVR and were registered in the nationwide registry for TAVR in Japan (Japanese Transcatheter Valvular Therapies registry) between 2013 and 2018. The rate of 30-day and 1-year mortality and composite adverse event, comprising all-cause death, all stroke, and life-threatening/major bleeding, were assessed. Results Of the 15,028 registered patients during the study period, 2,215 (14.7%) were nonagenarians. Although the nonagenarians were less likely to have comorbid conditions (eg, diabetes mellitus and malignancy) than patients aged <90 y, they had a higher Society of Thoracic Surgeons risk score (8.8% vs 5.6%), mainly owing to their advanced age. The procedural characteristics were identical between 2 groups. The rate of 30-day mortality and composite endpoint was similar, whereas 1-year mortality and composite adverse events were increased among nonagenarians (10.3% vs 6.8% and 13.5% vs 9.2%, respectively), and nonagenarians were independently associated with these endpoints (HR: 1.21; 95% CI: 1.03-1.42; P = 0.023; HR: 1.24; 95% CI: 1.07-1.42; P = 0.004). Conclusions Of the 15,028 TAVR procedures performed in Japan between 2013 and 2018, 14.7% were performed in nonagenarians. These patients were carefully selected by a multidisciplinary heart team and showed 21% and 24% increase of 1-year mortality and composite adverse outcome.

METHODS AND RESULTS In this multicenter, prospective, randomized, open-label, and blinded-endpoint investigator-initiated clinical trial, adults with type 2 diabetes and haemoglobin A1C (HbA1c) of 6.0-10.0% (42-86 mmol/mol) were randomized equally to ipragliflozin (50 mg daily) and non-sodium-glucose cotransporter-2 (SGLT2) inhibitor use of standard-care (control group) for type 2 diabetes and were followed-up to 24 months. The primary endpoint was the change in mean common carotid artery IMT (CCA-IMT) from baseline to 24 months. A total of 482 patients were equally allocated to the ipragliflozin (N = 241) and control (N = 241) groups, and 464 patients (median age 68 years, female 31.7%, median type 2 diabetes duration 8 years, median HbA1c 7.3%) were included in the analyses. For the primary endpoint, the changes in the mean CCA-IMT from baseline to 24 months were 0.0013 [95% confidence interval (CI), -0.0155-0.0182] mm and 0.0015 (95% CI, -0.0155-0.0184) mm in the ipragliflozin and control groups, respectively, with an estimated group difference (ipragliflozin-control) of -0.0001 mm (95% CI, -0.0191-0.0189; P = 0.989). A group difference in HbA1c change at 24 months was also non-significant between the treatment groups [-0.1% (95% CI, -0.2-0.1); P = 0.359]. CONCLUSION Twenty-four months of ipragliflozin treatment did not affect carotid IMT status in patients with type 2 diabetes recruited in the PROTECT study, relative to the non-SGLT2 inhibitor-use standard care for type 2 diabetes.

Abstract
A 60-year-old woman with a history of hypothyroidism was referred to our hospital for shortness of breath and a left ventricular ejection fraction (LVEF) of 13%, which required continuous dobutamine injection with intra-aortic balloon pump support. An endomyocardial biopsy obtained from the right ventricle revealed an infiltration of giant cells and eosinophils, indicating giant cell myocarditis. In addition to heart failure treatment, combined immunotherapy with steroids, tacrolimus, and intravenous immunoglobulin was administered. Transthoracic echocardiography demonstrated a dramatic improvement in the LVEF after this therapy, and the patient was discharged home without symptoms on day 72.

Abstract
Platypnea-orthodeoxia syndrome (POS) is a rare disease characterized by dyspnea and hypoxemia in orthostatism that improves in the recumbent position. We herein report an 81-year-old woman with dyspnea in the upright position following thoracic vertebral compression fractures. After the patient's daughter brought a recording showing decreasing SpO2 (peripheral capillary oxygen saturation) in the upright position as measured by a portable pulse oximeter outside the hospital, a small atrial septal defect (ASD) was detected. A contrast echocardiogram and four-dimensional flow magnetic resonance imaging demonstrated a right-to-left shunt. The patient's symptoms dramatically improved after percutaneous ASD closure. In conclusion, such new technologies are useful for diagnosing POS.

Abstract
Objective: A working group (WG) of the Japanese Society of Nuclear Cardiology (JSNC) determined Japanese normal databases of myocardial perfusion single-photon emission computed tomography (SPECT) on semi-conductor gamma camera (D-SPECT), and the aim of this study was to validate its clinical utility. Materials and methods: The normal myocardial perfusion SPECT (MPS) databases of Japanese patients in the 201Tl stress/redistribution protocol (201Tl protocol), 99mTc stress/rest or rest/stress protocol (99mTc protocol), and rest 99mTc/stress 201Tl simultaneous acquisition dual-isotope protocol (SDI protocol) were created by JSNC WG. The WG collected clinical cases for the 201Tl protocol (male/female [m/f], 8/8), 99mTc protocol (m/f, 9/7), and SDI protocol (m/f, 10/10) from WG participating hospitals. Four WG members read those clinical cases on a 17-segment and 5-point scale (0-4). Using the most frequent values as the score for each segment, weighted κ values were calculated with the scores obtained from quantitative perfusion software (QPS). Results: Weighted κ values were as follows; 201Tl stress/female, 0.77; 201Tl rest/female, 0.74; 201Tl stress/male, 0.81; 201Tl rest/male, 0.68; 99mTc stress/female, 0.77; 99mTc rest/female, 0.62; 99mTc stress/male, 0.77; 99mTc rest/male, 0.75; SDI stress/female, 0.87; SDI rest/female, 0.82; SDI stress/male, 0.87; SDI rest/male, 0.85. Conclusions: The diagnostic accuracy of Japanese MPS normal databases on D-SPECT were comparable with nuclear cardiology expert reading and further clinical applications are expected.

Abstract
BACKGROUND Recent retrospective investigations have suggested that optical coherence tomography (OCT) enables the diagnosis of underlying acute coronary syndrome (ACS) causes such as plaque rupture, plaque erosion, and calcified nodule. The relationships of these etiologies with clinical outcomes, and the clinical utility of OCT-guided primary percutaneous coronary intervention (PCI) are not systematically studied in real-world ACS treatment settings. METHODS The TACTICS registry is an investigator-initiated, prospective, multicenter, observational study to be conducted at 21 hospitals in Japan. A total of 700 patients with ACS (symptom onset within 24 h) undergoing OCT-guided primary PCI will be enrolled. The primary endpoint of the study is to identify the underlying causes of ACS using OCT-defined morphological assessment of the culprit lesion. The key secondary clinical endpoints are hazard ratios of the composite of cardiovascular death, non-fatal myocardial infarction, heart failure, or ischemia-driven revascularization in patients with underlying etiologies at the 12- and 24-month follow-ups. The feasibility of OCT-guided primary PCI for ACS will be assessed by the achievement rates of optimal post-procedural results and safety endpoints. CONCLUSION The TACTICS registry will provide an overview of the underlying causes of ACS using OCT, and will reveal any difference in clinical outcomes depending on the underlying causes. The registry will also inform on the feasibility of OCT-guided primary PCI for patients with ACS.

Abstract
Background The lesion formation properties of a motorized rotational delivery (RAPID) mode, third-generation laser balloon (LB3) ablation compared to point-by-point laser ablation in patients with atrial fibrillation remain unclear. Objective The purpose of this study was to assess lesion characteristics and thermodynamics in LB3 ablation with a RAPID mode in vitro model. Methods Chicken muscles were cauterized using LB3 in RAPID mode with 13 W and 15 W and 50% overlapped point-by-point fashion with 7 W/30 seconds, 8.5 W/20 seconds, 10 W/20 seconds, and 12 W/20 seconds. Lesion depth, width, and continuity were compared. Lesion continuity was classified by the visible gap degree categorized from 1 (perfect) to 3 (poor). Thermodynamics and maximum tissue temperatures were assessed under infrared thermographic monitoring. Fifteen and 5 lesions were evaluated per ablation protocol for measurement of lesion size and continuity and for thermographic assessment, respectively. Results Lesion depth and width were smaller in RAPID mode laser ablation than point-by-point laser ablation (P <.001). However, RAPID mode laser ablation revealed sufficient mean lesion depth of 5 mm or more. Lesion continuity was 1 (perfect) in all samples in RAPID mode laser ablation and point-by-point laser ablation (P = 1). Infrared thermographic observation demonstrated fast and gapless linear lesion formation with thermal stacking in RAPID mode laser ablation. Maximum tissue temperature was lower in RAPID mode laser ablation than point-by-point laser ablation (P <.001). Conclusion RAPID mode LB3 ablation could provide fast, gapless, and acceptable lesion formation with thermal stacking and moderate tissue temperature rise.

Abstract
Background Functional follow-up modalities of hypertrophic cardiomyopathy (HCM) with left ventricular (LV) outflow tract obstruction (LVOTO) subjected to alcohol septal ablation (ASA) are limited. Methods This retrospective cohort study included patients of HCM with LVOTO who underwent ASA and four-dimensional (4D) flow cardiac magnetic resonance imaging (MRI) both before and after ASA. We analyzed energy loss in one cardiac cycle within the three-chamber plane of the LV and aortic root, and compared between pre- and post-ASA measurements. Results Of the 26 included patients, 10 (39%) were male, and median age was 71 (interquartile range 58–78) years. ASA significantly reduced not only LVOT pressure gradient (70 [19–50] to 9 [3–16], P < 0.001), but also energy loss during one cardiac cycle within the three-chamber plane of the LV and aortic root (80 [65–99] to 56 [45–70], P < 0.001). A linear association was observed between the reductions of energy loss and pressure gradient (R2 = 0.58, P < 0.001). Conclusions ASA significantly reduced energy loss within the LV and aortic root as quantified by 4D flow MRI, reflecting the decreased cardiac workload. This approach is a promising candidate for serial functional follow-up in patients undergoing ASA.

Abstract
Information regarding fracture in patients with transcatheter aortic valve replacement (TAVR) is limited. We investigated the prevalence and impact of fracture in patients with severe aortic stenosis who had undergone TAVR. Of 913 consecutive patients with symptomatic, severe aortic stenosis who underwent TAVR at the Sakakibara Heart Institute between October 2013 and April 2020, 633 women were enrolled. The primary endpoint was all-cause mortality following TAVR. Patients with a history of fracture displayed smaller body mass indices, increased frailty, a higher prevalence of osteoporosis, and stroke history. Notably, 61.7% of patients with a history of fracture reported to have not taken any osteoporosis medications. Estimated all-cause mortality survival rates post-TAVR were significantly lower in patients with fractures than those without fractures. In the multivariate analysis, history of fracture was independently associated with all-cause mortality following TAVR. Furthermore, fracture prevalence was significantly greater in those who had a higher clinical frailty scale score were slower in the 5-m walk test, had more severe dementia as per the revised Hasegawa dementia scale, and performed poorly in the hand grip strength test. History of fracture was an independent predictor for all-cause mortality in patients undergoing TAVR. In addition, our study demonstrated that osteoporotic fracture may be under-treated in this population. History of fracture may be one of the phenotypes of frailty given its significant relationship with frailty markers in this population.

Abstract
The prognostic predictors of death or heart failure hospitalization and the echocardiographic response after initial cardiac resynchronization therapy (CRT) device replacement (CRT-r) remain unclear. We evaluated the predictors and the echocardiographic time course in patients after CRT-r. Consecutive 60 patients underwent CRT-r because of battery depletion. Patients were divided into two groups depending on the chronic echocardiographic response to CRT (left ventricular end-systolic volume [LVESV] reduction of ≥ 15%) at the time of CRT-r: CRT responders (group A; 35 patients) and CRT nonresponders (group B; 25 patients). The primary endpoint was a composite of death from any cause or heart failure hospitalization. Changes in LVESV and left ventricular ejection fraction (LVEF) after CRT-r were also analyzed. During the mean follow-up of 46 ± 33 months after CRT-r, the primary endpoint occurred more frequently in group B (group A versus group B; 8/35 [23%] patients versus 19/25 [76%] patients, p < 0.001). No significant changes in LVESV and LVEF were observed at the mean of 46 ± 29 months after CRT-r in both groups. A multivariate analysis identified echocardiographic nonresponse to CRT, chronic kidney disease, atrial fibrillation, and New York Heart Association functional class III or IV at the time of CRT-r as independent predictors of the primary endpoint in all patients. Residual echocardiographic nonresponse, comorbidities, and heart failure symptoms at the time of CRT-r predict the subsequent very long-term prognosis after CRT-r. No further echocardiographic response to CRT was found after CRT-r.
